GeForce RTX 3070 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which comes with a core clock frequency of 2055 MHz and a GDDR6 memory speed of 2190 MHz. It also makes use of a 128-bit bus, and makes use of a 7 nm design. It features 2048 SPUs, 128 Texture Address Units, and 64 ROPs.

GeForce RTX 3070		(Unknown) MB/sec
	Difference: 287072 (-100%)

Texel Rate

The GeForce RTX 3070 is a bit (approximately 5%) better at AF than the Radeon RX 6650 XT. (explain)

GeForce RTX 3070		276000 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 12960 (5%)

Pixel Rate

The GeForce RTX 3070 is a small bit (more or less 9%) faster with regards to AA than the Radeon RX 6650 XT, and will be capable of handling higher resolutions more effectively. (explain)

GeForce RTX 3070		144000 Mpixels/sec
Radeon RX 6650 XT		131520 Mpixels/sec
	Difference: 12480 (9%)

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 max amount of information (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of 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 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 amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the clock 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 fill rate also depends on many 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.
