GeForce GTX 1070 Ti vs Radeon RX 6650 XT

Intro

The GeForce GTX 1070 Ti comes with a GPU clock speed of 1607 MHz, and the 8192 MB of GDDR5 memory is set to run at 2000 MHz through a 256-bit bus. It also features 2432 SPUs, 152 Texture Address Units, and 64 ROPs.

Compare those specifications to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has clocked the core frequency at 2055 MHz. The GDDR6 memory works at a speed of 2190 MHz on this card. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Radeon RX 6650 XT 176 Watts
GeForce GTX 1070 Ti 180 Watts
Difference: 4 Watts (2%)

Memory Bandwidth

Performance-wise, the Radeon RX 6650 XT should in theory be a little bit superior to the GeForce GTX 1070 Ti overall. (explain)

Radeon RX 6650 XT 287072 MB/sec
GeForce GTX 1070 Ti 262144 MB/sec
Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT is a little bit (about 8%) better at AF than the GeForce GTX 1070 Ti. (explain)

Radeon RX 6650 XT 263040 Mtexels/sec
GeForce GTX 1070 Ti 244264 Mtexels/sec
Difference: 18776 (8%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is a better choice, and very much so. (explain)

Radeon RX 6650 XT 131520 Mpixels/sec
GeForce GTX 1070 Ti 102848 Mpixels/sec
Difference: 28672 (28%)

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 data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs 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 also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
