Radeon R9 295X2 vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which has core speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 95296 (36%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6650 XT is a better choice, not by a very large margin though. (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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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