Technical specs
General performance parameters such as number of shaders, GPU core base clock and boost clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results. Note that power consumption of some graphics cards can well exceed their nominal TDP, especially when overclocked.

| Core clock speed | 650 MHz | 625 MHz |
| Number of transistors | 292 million | 370 million |
| Manufacturing process technology | 40 nm | 40 nm |
| Power consumption (TDP) | 19 Watt | 18 Watt |
| Texture fill rate | 5.200 | 5.000 |
| Floating-point performance | 104 gflops | 200 gflops |
Size and compatibility
Information on compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For desktop graphics cards it's interface and bus (motherboard compatibility), additional power connectors (power supply compatibility).
| Interface | PCIe 2.0 x16 | PCIe 2.0 x16 |
| Length | 170 mm | 168 mm |
| Width | 1-slot | 1-slot |
| Supplementary power connectors | None | None |
Memory
Parameters of VRAM installed: its type, size, bus, clock and resulting bandwidth. Integrated GPUs have no dedicated video RAM and use a shared part of system RAM.
| Memory type | DDR2 | GDDR3 |
| Maximum RAM amount | 2 GB | 512 MB |
| Memory bus width | 64 Bit | 64 Bit |
| Memory clock speed | 800 MHz | 1066 MHz |
