Value for money

Performance to price ratio. The higher, the better.

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.

Pipelines / CUDA cores	1280	512
Boost clock speed	1050 MHz	1600 MHz
Number of transistors	2,800 million	2,400 million
Manufacturing process technology	28 nm	7 nm
Power consumption (TDP)	180 Watt	15 Watt
Texture fill rate	84.00	51.20
Floating-point performance	2,688 gflops	no data

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).
