Radeon R9 295X2 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which features a clock speed of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 64 Raster Operation Units.

Radeon RX 6600		229376 MB/sec
	Difference: 410624 (179%)

Texel Rate

The Radeon R9 295X2 is quite a bit (approximately 97%) better at texture filtering than the Radeon RX 6600. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon RX 6600		182112 Mtexels/sec
	Difference: 176224 (97%)

Pixel Rate

The Radeon R9 295X2 should be a lot (more or less 25%) faster with regards to AA than the Radeon RX 6600, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 295X2		130304 Mpixels/sec
Radeon RX 6600		104064 Mpixels/sec
	Difference: 26240 (25%)

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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
