GeForce GTX 650 vs Radeon RX 6950 XT

Intro

Compare all of that to the Radeon RX 6950 XT, which has a core clock speed of 1925 MHz and a GDDR6 memory frequency of 2250 MHz. It also features a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 Texture Address Units, and 128 Raster Operation Units.

GeForce GTX 650		80000 MB/sec
	Difference: 509824 (637%)

Texel Rate

The Radeon RX 6950 XT is much (more or less 1719%) faster with regards to texture filtering than the GeForce GTX 650. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 582144 (1719%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6950 XT is the winner, and very much so. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
GeForce GTX 650		16928 Mpixels/sec
	Difference: 229472 (1356%)

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 largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
