GeForce GTX 295 vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which has GPU clock speed of 1626 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 1792 SPUs, 112 Texture Address Units, and 64 ROPs.

Texel Rate

The Radeon RX 6600 should be much (approximately 98%) more effective at AF than the GeForce GTX 295. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 89952 (98%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6600 is superior to the GeForce GTX 295, by a large margin. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 71808 (223%)

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 megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of 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 fill rate also depends 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.
