GeForce GTX 275 vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which has core clock speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 RAM. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Texel Rate

The Radeon RX 6500 XT will be a lot (approximately 178%) faster with regards to anisotropic filtering than the GeForce GTX 275. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 90160 (178%)

Pixel Rate

The Radeon RX 6500 XT should be much (about 297%) more effective at full screen anti-aliasing than the GeForce GTX 275, and also able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 52676 (297%)

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 data (in units of megabytes per second) that can be transferred across 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 type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better 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 one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
