Radeon R9 295X2 vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this model. It features 1792 SPUs as well as 112 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
Radeon R9 295X2		500 Watts
	Difference: 368 Watts (279%)

Memory Bandwidth

In theory, the Radeon R9 295X2 should be quite a bit faster than the Radeon RX 6600 overall. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 410624 (179%)

Texel Rate

The Radeon R9 295X2 is a lot (about 97%) more effective 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 is much (more or less 25%) faster with regards to anti-aliasing than the Radeon RX 6600, and also should be able to handle higher 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 data (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
