Detailed specifications

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	810 MHz	600 MHz
Number of transistors	292 million	720 million
Manufacturing process technology	40 nm	80 nm
Power consumption (TDP)	30 Watt	200 Watt
Texture fill rate	6.480	9.600
Floating-point performance	155.5 gflops	384.0 gflops

Form factor & 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).
