GeForce RTX 3070 vs Radeon RX 6650 XT

Intro

The GeForce RTX 3070 has core speeds of 1500 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 5888 SPUs as well as 184 Texture Address Units and 96 ROPs.

Compare that to the Radeon RX 6650 XT, which comes with a GPU core clock speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6650 XT 287072 MB/sec
GeForce RTX 3070 (Unknown) MB/sec
Difference: 287072 (-100%)

Texel Rate

The GeForce RTX 3070 is a little bit (approximately 5%) more effective at texture filtering than the Radeon RX 6650 XT. (explain)

GeForce RTX 3070 276000 Mtexels/sec
Radeon RX 6650 XT 263040 Mtexels/sec
Difference: 12960 (5%)

Pixel Rate

The GeForce RTX 3070 is a small bit (about 9%) more effective at anti-aliasing than the Radeon RX 6650 XT, and should be capable of handling higher resolutions while still performing well. (explain)

GeForce RTX 3070 144000 Mpixels/sec
Radeon RX 6650 XT 131520 Mpixels/sec
Difference: 12480 (9%)

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: Bandwidth is the max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to get to the maximum fill rate.
