GeForce GTX 1070 vs Radeon RX 6650 XT

Intro

Compare that to the Radeon RX 6650 XT, which comes with core speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

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

Texel Rate

The Radeon RX 6650 XT will be much (about 46%) more effective at AF than the GeForce GTX 1070. (explain)

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

Pixel Rate

The Radeon RX 6650 XT is quite a bit (more or less 36%) better at FSAA than the GeForce GTX 1070, and capable of handling higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write 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 card's clock speed. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
