GeForce GTX 1070 vs Radeon RX 6650 XT

Intro

The GeForce GTX 1070 uses a 16 nm design. nVidia has clocked the core frequency at 1506 MHz. The GDDR5 memory is set to run at a speed of 2000 MHz on this card. It features 1920 SPUs along with 120 Texture Address Units and 64 Rasterization Operator Units.

Compare those specifications to the Radeon RX 6650 XT, which features a clock speed of 2055 MHz and a GDDR6 memory speed of 2190 MHz. It also makes use of a 128-bit bus, and uses a 7 nm design. It features 2048 SPUs, 128 TAUs, and 64 ROPs.

GeForce GTX 1070 262144 MB/sec
Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT is a lot (more or less 46%) more effective at anisotropic filtering than the GeForce GTX 1070. (explain)

Radeon RX 6650 XT 263040 Mtexels/sec
GeForce GTX 1070 180720 Mtexels/sec
Difference: 82320 (46%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6650 XT is the winner, by a large margin. (explain)

Radeon RX 6650 XT 131520 Mpixels/sec
GeForce GTX 1070 96384 Mpixels/sec
Difference: 35136 (36%)

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 max amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, 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 that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
