The AMD E-450 is a refresh of the E-350 Fusion Accelerated Processing Unit, both aimed at cheap full-size notebooks, netbooks, and small form factor desktop computers.
AMD E-450 & AMD Radeon HD 6320 Specifications
The E-450 doesn’t bring any revolutionary improvement over the E-350, both belonging to the AMD “Zacate” E series. Its dual CPU cores are clocked at 1.65GHz versus 1.6GHz in the E-350. As for its ingegrated graphics, the E-450 includes the AMD Radeon HD 6320 instead of the 6210. The graphics refresh is the biggest improvement in the new APU. The 6320 GPU can run in Turbo mode, dynamically adjusting graphics clock speed in a range from 508MHz to 600MHz, in order to deliver better performance and lower power consumption.
Another upgrade is regarding memory clock. The E-450 supports up to 1333Hz RAM, versus previous maximal 1066Mhz. However, not many E-450-based laptops will be able to support the increased memory speed, because they come with 1066MHz memory modules.
Here are the specifications of the AMD E-450 with the Radeon HD 6320 graphics:
- dual CPU cores at 1.65GHz, with 512KB of L2 cache per core
- 80 graphics shader units; clock speed of 508MHz to 600MHz, adjusted by Turbo technology
- UVD3 full HD video decoder
- Thermal Design Power of 18W
- 64-bit computing and virtualization supported
- support for 1066 and 1333MHz memory
- 40-nanometer production technology
Our test system is the recently reviewed Asus K53U 15.6-inch laptop with the AMD E-450, 4GB of DDR3 1066MHz RAM, a 500GB 5,400rpm hard drive, 1366×768 screen resolution, and Windows 7 Home Premium OS.
AMD E-450 CPU Performance Benchmark
The dual CPU cores are not fast, even when compared to budget-class Intel counterparts, such as the latest Celeron processors. On the other side, it is faster than the fastest Intel Atom processor – the N570, and is way better in terms of performace than the 8W “Ontario” C-series AMD APUs.
AMD Radeon HD 6320 Gaming Graphics Benchmark
The AMD E-450 with its AMD Radeon HD 6320 integrated graphics is good for playing older, less hardware demanding games, such as Quake 4 or Half Life 2: Lost Coast. You can play Quake 4 at 1280×720 resolution at High Settings at 45 frames per second. Half Life 2 at laptop’s native resolution of 1366×768 with all settings set to max, including anti-aliasing and anti-strophic filtering, scores 42fps. With AA and AF disabled, it scores 46fps.
Newer games which require better hadrware specs – like Crysis, Lost Planet 2, and Far Cry 2 – are playable only on minimal settings at 1280×720. Crysis at its lowest settings runs at 26fps on average, while for Lost Planet 2 and Far Cry 2 it’s 24 and 23fps, respectively.
HD 1080p Video Decoding
One of the important features on the E-450 is the Unified Video Decoder 3, which provides hardware decoding of high-definition videos. Without it, HD video decoding would throttle the CPU cores, but with it the CPU load during decoding increases only between 6 and 14 percent. So, with the APU, you have ample of processor capacity for other tasks and smooth full HD video playback.
Conclusion About AMD E-450 & AMD Radeon HD 6320
This single-die CPU/GPU combination is good for usual computer tasks, which doesn’t demand high-end hardware. The E-450 is good for Web, e-mail, light work in office suites, and fully supports 1080p video playback thanks to the UVD3. It’s Radeon HD 6320 integrated graphics is good for playing older game titles. It is also possible to play newer games, but only on lowest settings. When compared to the E-350, performance improvement exists, although it’s not big. However, the main advantage of the E-450 over many other chips is its affordability, enabling full-size laptop prices of as low as $400.
