Compare any two graphics cards:
GeForce RTX 2070 Super vs Radeon RX 5700
IntroThe GeForce RTX 2070 Super comes with a GPU core speed of 1605 MHz, and the 8192 MB of GDDR6 memory is set to run at 14000 MHz through a 256-bit bus. It also is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.
Compare those specs to the Radeon RX 5700, which features a clock frequency of 1465 MHz and a GDDR6 memory frequency of 14000 MHz. It also uses a 256-bit bus, and makes use of a 7 nm design. It features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce RTX 2070 Super is much (approximately 22%) faster with regards to texture filtering than the Radeon RX 5700. (explain)
Pixel RateThe GeForce RTX 2070 Super should be a little bit (about 10%) better at FSAA than the Radeon RX 5700, and will be able to handle higher screen resolutions without losing too much performance. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
