Compare any two graphics cards:
Radeon RX 6900 XT vs Radeon RX 6950 XT
IntroThe Radeon RX 6900 XT features core clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.
Compare those specifications to the Radeon RX 6950 XT, which features a clock speed of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also makes use of a 256-bit bus, and uses a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Radeon RX 6950 XT should be a small bit faster than the Radeon RX 6900 XT in general. (explain)
Texel RateThe Radeon RX 6950 XT will be a bit (more or less 5%) better at anisotropic filtering than the Radeon RX 6900 XT. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon RX 6950 XT is a better choice, but it probably won't make a huge difference. (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 largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
