GeForce RTX 3070 Ti vs Radeon RX 6650 XT

Intro

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 is set to run at a speed of 2190 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3070 Ti should be much faster than the Radeon RX 6650 XT in general. (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 should be just a bit (approximately 15%) more effective at texture filtering 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 using high levels of AA is important to you, then the GeForce RTX 3070 Ti is a better choice, but it probably won't make a huge difference. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
