Cost-effectiveness evaluation

Performance to price ratio. The higher, the better.

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	1100 MHz	920 MHz
Boost clock speed	1183 MHz	980 MHz
Number of transistors	2,200 million	1,550 million
Manufacturing process technology	14 nm	28 nm
Power consumption (TDP)	50 Watt	no data
Texture fill rate	37.86	22.08
Floating-point performance	1,211 gflops	no data

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).

Interface	PCIe 3.0 x8	PCIe 3.0 x8
Length	145 mm	no data
Width	2-slot	no data
