Radeon R9 295X2 vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which features GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 RAM set to run at 2190 MHz through a 128-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 64 ROPs.

Radeon RX 6650 XT		287072 MB/sec
	Difference: 352928 (123%)

Texel Rate

The Radeon R9 295X2 should be quite a bit (approximately 36%) more effective at texture filtering than the Radeon RX 6650 XT. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 95296 (36%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6650 XT is the winner, though only just barely. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon R9 295X2		130304 Mpixels/sec
	Difference: 1216 (1%)

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 (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the clock 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
