Note: The Asus Q550LF-BSI7T21 has the same hardware as the older Q550LF-BBI7T07 model. The only difference between these two laptops appears to be their OS versions, with the former having Windows 8.1 pre-installed instead of Win 8.0 (which is upgradeable to 8.1 for free).

The Q550LF-BBI7T07 is a 15.6-inch touchscreen laptop which packs the latest higher-end components in a sleek design.

There’s plenty to like on it. The most remarkable features, besides the touch-enabled display with full HD 1080p resolution, are the latest 4th Generation Intel Core i7 processor with good performance and low power consumption, the Nvidia GeForce GT 745M dedicated video card with 2GB of DDR3 video memory, 8GB of RAM, and a 1,000GB (1TB) hard disk drive, all encased in an brushed “hairline” aluminum 1.1″-thin 6-pound chassis in dark gray color. The notebook is equipped with a silverish LED-backlit chiclet keyboard with numeric pad and a spacious seamless trackpad with integrated click buttons.

The included i7-4500U has two cores and runs at 1.8GHz default or up to 3GHz in TurboBoost mode. According to PassMark, it isn’t faster than the previous generation i7-3517U at 1.9GHz-3GHz. That’s a kind of expected because the 4th Generation i7 ultra-low voltage parts are designed primarily with power efficiency in mind, not high-performance. However, the i7-4500U is a higher-end part in the world of thin-and-light laptops and is suitable for daily tasks (social networking, web, office) as well as multimedia creation (video and image editing).

Intel Core i7-4500U Benchmark

Nvidia’s GT 745M isn’t a gaming-level graphics card, but it certainly passes playability threshold for many of the latest 3D games, even on high settings on some game titles.

8GB of RAM and 1TB of hard drive space are double the amounts found in the ordinary notebooks with usual 4GB and 500GB. Although even 4GB is enough for all daily tasks, in the era of large-size HD video files it’s always good to have as much storage space as possible and the Asus Q550LF-BSI7T21 has the maximal storage capacity on the market if you don’t count multi-HDD laptops. The laptop also has a DVD burner for even more storage and you additionally has three USB 3.0 ports for Flash drives and other peripherals, as well as an SD/MMC reader for media cards. Other ports and slots are VGA and HDMI video outputs, a headphone/mic combo jack, and Gigabit LAN port. For wireless connectivity, there’s a built-in 802.11n Wi-Fi module and Bluetooth. The battery is quite large, with 59WHr. It should last more than five hours.

All of the listed features of this well armed notebook make it more expensive than many of the touchscreen 15.6-inch laptops. This Asus costs $1,000, whereas some of its touch-enabled competitors cost almost a half less.

  1. Joseph

    Not sure if this has already been mentioned, but the other difference between this and the BBI7T07 is that this has Wireless AC vs. Wireless N. Other than that and the OS, they are identical.

  2. Sara

    I am looking for a laptop to do multiple tasks at a ranch. It will be used to view, store and crop pictures from game cameras; Microsoft Office programs and for fun, ability to play Facebook games such as Pogo and Hit It Rich. The laptop needs to have a disk drive to view and copy equipment repair manuals.

    Talked with BB tech and he said the Asus Q550LF-BS17T21 is what I need. I am not knowledgeable on laptops but want to be sure this is a good fit for what I need and will last a few years. Any info or suggestions are greatly appreciated.

      Sara, the Q550LF-BS17T21 is a higher-end laptop while your tasks seem to be quite light. The chances are you won’t notice big difference in these tasks between the Asus and many of the much cheaper models for let’s say $500 or more. The Q550LF clearly has its advantages, such as the sharp display with wide viewing angles and backlight keyboard.
      But, this Dell laptop for example has almost the same specs (but has no DVD drive) and costs noticeably less:

      The Nvidia 745M graphics card in the Asus is an extra feature if you compare it to the average laptop. It will make 3D gamers run smoother than on the ordinary notebook, but if you don’t plan to play these it’s an additional cost with no good reason.

      If you want to stick to Asus brand, take a look at a model which is a kind of an updated version of the Q550LF-BSI7T21, with convertible design and newer CPU & video card:

    great idea.. thanks for your help

  4. steve

    Thanks for your answer. for those who like to know its an usb 2.0 with realtek driver. which now makes me wonder. can I swap that out for a usb 3.0 reader? im not finding any conversions on google. lol one thing leads to another.

    • Danijel Z

      Danijel Z

      Really don’t know. For sure, it wouldn’t be as easy as replacing RAM or HDD. Even if you can, the question is will it void the warranty. Have you considered a USB 3.0 flash drive instead?

  5. steve

    Thank you for the review. I have a question….and ill post a personal review.
    I bought this open box from BB and got a good deal. I needed it because it had a relatively good graphics card and an i7 processor that I needed to use to work on adobe LR5, CC2014,PP2014 and After Effects 2014. after purchase I found three things: the i7 is only dual core, the graphics card could be better( but usable), and the 1TB HD is painfully slow. and sometimes using the keyboard you don’t know exactly what just happened but it did something lol.

    To remedy this I installed a Samsung 840 SSD (not the pro version) 256GB. I took out the dvd drive and put in a drive holder for the SSD, Kept the 1TB drive in for a backup. The HD really kept the laptop running very slow. I took it out, ran with just the SSD and then put the HD back in and wiped it. This speeded things up tremendously , especially with the rapid mode in Samsung magician. so now my laptop boots up in 3 Seconds ! another 2 seconds to sign in windows and im on. WOW.

    So now the 1TB drive is reformatted and used as storage. This is the fastest boot-up computer I own now. and I use it on the road to store lots of photos.

    My question now is. I think id like to remove the 1TB drive and re-install a new Blu-ray burner. Then just get a 512 GB SD card and pop it in the side as my storage. But I cant find specs on what size SD card the side card reader can handle. will it handle fast large 512 gb SDXC cards? I believe a SDXC card is faster than the 5400 rpm HD inside, your thoughts on this please?

    • Danijel Z

      Danijel Z

      I don’t have info on the card reader, but I would use Control Panel > Device Manager > Memory Technology Devices then Properties > Details > Hardware IDs or HWInfo app (easier way) to find out the card reader product name, then do Google Search for specs of the device. Keep in mind that read/write speeds will depend not only on the speed of the card, but also on speed of the card reader. Some laptops have slow readers, so using fast cards with them doesn’t make sense.

  6. Rub

    Could this laptop be good for photo editing?
    Thank you for the help.

  7. Robert

    This laptop is perfect for me. I am a college math major, and it can run complex programs with ease 🙂
    Do buy!

  8. Rated 5 out of 5


    I’ve been looking for a laptop, that is good for animation(both 2d & 3d) and gaming, specifically Sims 3. I also need it for long tedious home work. I found the Asus g55olf bsi7t21 and am wondering if its a good choice.

    • Danijel Z

      Cat, in one of the comments above I’ve recommended the Lenovo Y50 instead of the Asus for tasks similar to yours. “I advise you to take a look at the Lenovo Y50. It’s available here: for only 50 bucks more than the Q550LF-BSI7T21 and has way better components…”. I can recommend you the same, if a built-in DVD isn’t a must. You can also take into consideration other models with a quad-core i7 CPU and the Nvidia 850M GPU or above.

  9. Juls

    Thanks so much for your expertise and opinion on these. The info you provides and explained helped me a lot. When I buy one I’ll be sure to let ya know how it’s doing. Thanks again!

  10. Juls

    I looked up the one you recommended and that is a good option I also looked up a similar one that had more memory, the Asus G750JM-DS71. Out of those we have discussed that have a DVD burner how would rate them for my intended use and why?

    • Danijel Z

      Danijel Z

      Well, for the tasks you’ve mentioned I would certainly recommend a model with a quad-core i7-4700HQ/4710HQ (Asus G750, G550) instead of dual-core i7-4500U (Asus Q550). The former have double the score of the latter in many benchmarks. For instance, in PassMark the results are around 8,000 versus 4,000 points in favor of the quad-core i7 chips. That can make a major difference, since you do video & photo editing and that can be quite demanding hardware-wise.

      Another difference is related to gaming. The 860M in the Asus G750 is noticeably better than the 850M in the G550JK, but even the 850M can handle Skyrim on 1080p and high settings perfectly. The higher performance of the 860M can be of use in other games. You can check out some benchmarks here: . The GT 745M in the Asus Q550 lags between both 800M-series GPUs a lot.

      As for RAM memory, I don’t think you’ll see any benefit from getting 12GB of RAM instead of 8GB, since 8GB is already quite enough even for demanding tasks. I use a laptop with 4GB for my daily work including photo and video editing and had no RAM size related issues so far. And you can upgrade RAM later if you wish, since is it can be easily done on the G750.

      As for the touchscreen, I don’t think it’s very usable on a classic laptop. I personally use it only for the simplest things like program launching and closing. For everything else, my opinion is that the keyboard and mouse do a better job, because of keyboard shortcuts, mouse pointer which is more precise than finger, scroll-wheel for web browser scrolling on the mouse etc.

      So, if you’re fine with the bigger size and heavier weight of the G750, I think the best choice among the mentioned laptops for your tasks is the g750jm-bs17n23.

  11. Juls

    What’s your opinion on this one? asus model# g750jm-bs17n23 It’s 300 more. But I’m just not sure if the better component and higher expandable memory are worth the added cost being it’s not touch screen and doesn’t have the cool added software addition that the original Asus laptop has that I asked you about. I saw both units today at BestBuy and the sales rep thought I’d be happier with the faster larger one. But I’m not convinced yet because of its weight difference and not touch screen and no added software. But I guess I really don’t know the true benefits of having a touch screen either. So I guess that’s why I’m a little confused as to what would be a better deal and work better for me in the long run. Your opinion is greatly appreciated

  12. Juls

    Of the Lenovo Y50 doesn’t have an optical drive? At least that’s what the comparison menu said if I understood it correctly. Id like to have a DVD/CD burner. I’m now looking to see if any of the Y50’s have one and what that price difference would be.

    • Danijel Z

      Danijel Z

      In that case, the Y50 isn’t for you, since there’s no Y50 model with DVD. Unless you’re willing to buy an external DVD drive. Here’s another similarly priced option: . It has IPS screen, DVD, quad-core i7, and GeForce 850M.

      Update: It appears to be out of stock everywhere at this time.

  13. Juls

    I am looking to buy the Asus Q550LF-BSI7T21 but want your opinion if this will work for what I want to do with it. It will be used for games like Skyrim & COD, working with pics and videos, would need to install Microsoft Office and “maybe” Quickbooks or something similar at some point in time and of course general surfing the web. I want something that’s gonna be snappy that I can see clearly without braking the bank. Thanks

    • Danijel Z

      Danijel Z

      I advise you to take a look at the Lenovo Y50. It’s available here: for only 50 bucks more than the Q550LF-BSI7T21 and has way better components. Both the CPU and video card (quad-core i7, Nvidia 860M) are class ahead of those in the Asus and that’s of a great importance for the tasks you mentioned. Especially gaming. In my opinion, the only advantage of the Asus are wider viewing angles since it has IPS screen technology. The Asus also has a bigger hard drive, but the Lenovo has hybrid HDD/SSD storage so it should respond faster than the Asus.

    Hello. To whom it may concern.

    I bought at BestBuy a ASUS Q550LF-BBi7TO7 Laptop. I want to upgrade the RAM to 16GB but BestBuy does not carry the type I need and I understand it is a specific type. I presume it is a low Voltage type and probably Crucial makes it. BUT obviously I need the specific model and part number. Please help….I am very stressed. Thanks. Bart.

      Hi, you can install this free application and run it to find out which exact RAM module your laptop has. It’ll also display RAM specs, so you can know which RAM modules are matching.

  15. Ken Sperry

    I just purchased this machine but they were out of stock at the store. Will have it in a few days. Wife is a graphic designer. Assuming it will be great for her. Comes with a dedicated graphics card.

  16. Erica Schulze

    How does it differ from the N series?

  17. Darryl Gardner

    @Danijel: If you’re having a problem with overheating on your laptops, consider the ASUS ROG series.

    A couple of years ago, when we purchased a laptop for one of our grandkids, the first thing I checked was to lift each model (which had been running all day) and feel the entire bottom of the case to see which was the coolest. And the ROG model was by far the coolest.

    Granted, this may not be a completely valid method of comparison, nevertheless is is one easy way to determine which operated coolest under the circumstances.

    Upon looking at the cooling method, ROG did not use the bottom to transfer air. It uses the front (intake) and back (exhaust), so setting it on a soft surface won’t block the ports.

    They are a bit pricey, starting at about $1250 at Best Buy and elsewhere.

    Features: i7 CPU, at least 12Gb RAM and 1TB HD, separate video card, dedicated space for a second drive in 17.3″ models.

    One last comment: The 17.3″ ROG models are LARGE, particularly the front to back dimension and to a lesser extent the height or thickness. So not just any 17″ bag will fit. We searched several places before finding a bag to accommodate such a large laptop and give it excellent protection. The one we chose was a leather Targus model (I just now looked at their site and they have several to choose from) that will accommodate the largest of 17″ or 17.3″ laptops, and they cost about $85.

    Hope this helps.

    Acquired in Miami this computer, very satisfied, in Russia such costs three times more expensive. Great value, would recommend.

  19. xXGrizZ

    Thanks for the response. I have since come across something about this laptop that is a deal breaker for me sadly. I have gone through too many laptops because of heating issues. I use a laptop all day during work and then take it home and use it during the evening – It essentially is being used all day – every day. This laptop only has 2 small air intake vents on the bottom and no exhaust vent. Additionally, I discovered that its battery is integrated and can’t be removed without voiding the warranty (which I like to do and just run the laptop via the A/C adapter- again for cooling.)

    I think I’m now going to go with the lower-end G750 which easily allows me to upgrade to 32GB of RAM and has an available separate bay for an SSD.

  20. xXGrizZ

    I am considering getting this laptop as well but had a few questions. Is it possible to either switch out the HDD for or add a SSD? Also, I read in someones purchase review that while it is expandable to 16GB of RAM, it is only a specific type of RAM that best buy (where it was purchased) doesn’t even carry. I would appreciate any info you can give.

  21. Danijel

    Yes, it will run it easily, but I think this model isn’t optimized for that. This is rather an entertainment machine. The Nvidia graphics card in it adds to the price, but you won’t need it for Quickbooks. For improved performance, it would be nice to have a solid state drive instead of the traditional HDD, or at least SSD/HDD hybrid. If you need an advice about alternatives to this, please tell me what you’ll use the laptop for except Quickbooks, your budget, and prefered screen size.

  22. Kitkat

    Would this be a smart laptop to run Quickbooks with?

  23. A guy with this laptop

    @brian: Yes, at least with the student version it runs smoothly with out much lag I had some installation troubles but it was my fault not the computers. I highly recomend it.

  24. dyseman

    (Quoted in article) All of the listed features of this well armed notebook make it more expensive than many of the touchscreen 15.6-inch laptops. The Q550LF-BBI7T07 costs $1,000, whereas some of its touch-enabled competitors cost almost a half less. A nice one is Lenovo’s P500 Touch 59374199 with a $650 price tag and 1 pound lower weight (5lbs). (End Quote)

    (My Argument)
    Yeah, $650 is a lower price. But it is a MUCH lower spec’d computer. It’s a 3rd Gen i5, not 4thj Gen i7. No nVidia card and only 720p vs 1080p. So not Apples to Apples. You get what you pay for. No included Subwoofer port or Included Subwoofer to plug in to said port. Backlit Keyboart at various intensities.
    (End Rant)

    (My Review)
    I’ve had this laptop over a month and can’t find anything comparable to this price point. Games play AWESOME on it! RIFT/EQ2/Skyrim/Might Quest Epic Loot etc… All on Max Settings. Edit’s Video nicely. Touch screen is VERY responsive and the WIDI works like a champ!

  25. Robby

    i bought this a week ago it can play skyrim on max settings and max settings on Battlefield 3 and it only use’s the video card when needed it runs on intel hd 4400 graphics otherwise

  26. brian

    looking to buy this laptop, is it compatible with Solidworks 2013-14?

  27. Ronald

    How is it as far as gaming? Or photo editing?

  28. Nitsuj

    In response to your battery query: I recently bought one of these and a typical moderate-usage session with about 60% backlight in power-save mode can go 5-6 hours.

    The Nvidia card is only used on demand. The laptop is also equipped with integrated graphics, and this chipset is used whenever possible to maximize battery life.

  29. miranda

    Is it a good laptop? I’m planning purchase for my son. He plays Angry Birds type of games and Netflix. And Word and Excel for school.

    • Danijel Z

      Danijel Z

      It’s good for light games, Netflix, and Office apps. In fact, this laptop speed-wise is an overkill for these tasks. You can do the same on almost every other model on the market, even the much cheaper ones. If you don’t plan to do anything complex (video processing, Photoshop etc), you’ll be fine with any cheap laptop with an let’s say Intel Pentium processor. As a side note, the Q550LF-BSI7T21 has an excellent screen with resolution higher than on budget laptops (1080p) and with IPS technology for wider viewing angles and better picture. For Netflix and movie watching in general this is a great advantage.

  30. Rated 3 out of 5


    @dariel: True, they’ve gone too far with dedicated GeForce in tiny base. If you’re not into gaming than it can be OK laptop.

  31. dariel

    this is a very tricky machine….you cant play you cant render anything in 3D in less than 20 minutes( a basical Vray render) its just an empty shell at a very high cost….try MSI GP70, sheeper and better!!!! ahhhh it get so ****** hot when gaming!!!! 40fps down to 19fps~21fps….a bag full of lie…i strongly recomend not to buy this pice of…

  32. Danijel


    This is a brand new model without reviews yet, but given it’s the same as the older Q550LF-BBI7T07 hardware-wise, the battery should last more than 4.5 hours when used for light tasks. That’s what reviews say.
