GeForce RTX 4080 vs Radeon VII

Intro

The GeForce RTX 4080 has a core clock frequency of 2205 MHz and a GDDR6X memory speed of 1400 MHz. It also makes use of a 256-bit bus, and makes use of a 4 nm design. It is comprised of 9728 SPUs, 304 TAUs, and 112 Raster Operation Units.

Compare those specs to the Radeon VII, which has a GPU core clock speed of 1400 MHz, and 16384 MB of HBM2 RAM set to run at 1000 MHz through a 4096-bit bus. It also features 3840 Stream Processors, 240 TAUs, and 64 ROPs.

Radeon VII 336000 Mtexels/sec
Difference: 334320 (100%)

Pixel Rate

The GeForce RTX 4080 should be a lot (about 176%) better at anti-aliasing than the Radeon VII, and also will be able to handle higher resolutions without slowing down too much. (explain)

GeForce RTX 4080 246960 Mpixels/sec
Radeon VII 89600 Mpixels/sec
Difference: 157360 (176%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at 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 card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
