Radeon R9 295X2 vs Radeon RX 6600 XT

Intro

The Radeon R9 295X2 features core clock speeds of 1018 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 memory. It features 2816 SPUs as well as 176 TAUs and 64 Rasterization Operator Units.

Compare all of that to the Radeon RX 6600 XT, which comes with clock speeds of 1968 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR6 memory. It features 2048 SPUs along with 128 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT 160 Watts
Radeon R9 295X2 500 Watts
Difference: 340 Watts (213%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 295X2 should be 144% faster than the Radeon RX 6600 XT overall, due to its higher bandwidth. (explain)

Radeon R9 295X2 640000 MB/sec
Radeon RX 6600 XT 262144 MB/sec
Difference: 377856 (144%)

Texel Rate

The Radeon R9 295X2 should be a lot (approximately 42%) more effective at texture filtering than the Radeon RX 6600 XT. (explain)

Radeon R9 295X2 358336 Mtexels/sec
Radeon RX 6600 XT 251904 Mtexels/sec
Difference: 106432 (42%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 295X2 is a better choice, not by a very large margin though. (explain)

Radeon R9 295X2 130304 Mpixels/sec
Radeon RX 6600 XT 125952 Mpixels/sec
Difference: 4352 (3%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few 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.
