Radeon R9 295X2 vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which has a GPU core clock speed of 2200 MHz, and 4096 MB of GDDR6 memory running at 2250 MHz through a 64-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Radeon RX 6500 XT		147456 MB/sec
	Difference: 492544 (334%)

Texel Rate

The Radeon R9 295X2 should be much (approximately 155%) more effective at texture filtering than the Radeon RX 6500 XT. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 217536 (155%)

Pixel Rate

The Radeon R9 295X2 is quite a bit (about 85%) better at AA than the Radeon RX 6500 XT, and should be able to handle higher resolutions more effectively. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 59904 (85%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
