Compare any two graphics cards:
Radeon RX 6750 XT vs Radeon RX Vega 64
IntroThe Radeon RX 6750 XT has a GPU clock speed of 2150 MHz, and the 12288 MB of GDDR6 RAM is set to run at 2250 MHz through a 192-bit bus. It also features 2560 Stream Processors, 160 TAUs, and 64 ROPs.
Compare those specs to the Radeon RX Vega 64, which comes with core speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Radeon RX Vega 64 should perform a little bit faster than the Radeon RX 6750 XT overall. (explain)
Texel RateThe Radeon RX 6750 XT will be just a bit (more or less 8%) more effective at AF than the Radeon RX Vega 64. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon RX 6750 XT is a better choice, by far. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
