VS

GeForce GTX 1070 Ti vs Radeon RX 6600 XT

Intro

The GeForce GTX 1070 Ti comes with a core clock frequency of 1607 MHz and a GDDR5 memory frequency of 2000 MHz. It also features a 256-bit memory bus, and makes use of a 16 nm design. It features 2432 SPUs, 152 TAUs, and 64 Raster Operation Units.

Compare all of that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has set the core frequency at 1968 MHz. The GDDR6 memory is set to run at a frequency of 2000 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT 160 Watts
GeForce GTX 1070 Ti 180 Watts
Difference: 20 Watts (13%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon RX 6600 XT is just a bit (more or less 3%) faster with regards to texture filtering than the GeForce GTX 1070 Ti. (explain)

Radeon RX 6600 XT 251904 Mtexels/sec
GeForce GTX 1070 Ti 244264 Mtexels/sec
Difference: 7640 (3%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6600 XT is superior to the GeForce GTX 1070 Ti, by far. (explain)

Radeon RX 6600 XT 125952 Mpixels/sec
GeForce GTX 1070 Ti 102848 Mpixels/sec
Difference: 23104 (22%)

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 megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
