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	640	448
Core clock speed	1218 MHz	no data
Boost clock speed	1218 MHz	1900 MHz
Number of transistors	2,200 million	9,800 million
Manufacturing process technology	14 nm	7 nm
Power consumption (TDP)	50 Watt	45 Watt
Texture fill rate	38.98	53.20

Size and compatibility

Information on Radeon RX 640 and Radeon Vega 7 Mobile compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
