GeForce RTX 3070 Ti vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has clocked the core speed at 2055 MHz. The GDDR6 RAM runs at a frequency of 2190 MHz on this card. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Radeon RX 6650 XT		176 Watts
GeForce RTX 3070 Ti		290 Watts
	Difference: 114 Watts (65%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 3070 Ti should in theory be quite a bit superior to the Radeon RX 6650 XT overall. (explain)

GeForce RTX 3070 Ti		622899 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 335827 (117%)

Texel Rate

The GeForce RTX 3070 Ti is a small bit (about 15%) faster with regards to AF than the Radeon RX 6650 XT. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 39360 (15%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 3070 Ti is the winner, though not by far. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon RX 6650 XT		131520 Mpixels/sec
	Difference: 19680 (15%)

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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
