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 | 668 MHz | 750 MHz |
| Number of transistors | 666 million | 514 million |
| Manufacturing process technology | 55 nm | 55 nm |
| Power consumption (TDP) | 75 Watt | 59 Watt |
| Texture fill rate | 10.69 | 24.00 |
| Floating-point performance | 427.5 gflops | 480.0 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 | AGP 8x |
