Radeon R9 295X2 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this model. It features 5120 SPUs as well as 320 TAUs and 128 Rasterization Operator Units.

Texel Rate

The Radeon RX 6900 XT should be quite a bit (approximately 63%) more effective at anisotropic filtering than the Radeon R9 295X2. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R9 295X2		358336 Mtexels/sec
	Difference: 225664 (63%)

Pixel Rate

The Radeon RX 6900 XT will be quite a bit (more or less 79%) better at AA than the Radeon R9 295X2, and should be capable of handling higher resolutions better. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R9 295X2		130304 Mpixels/sec
	Difference: 103296 (79%)

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 information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to reach the maximum fill rate.
