Radeon R9 M295X vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which comes with a clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M295X		125 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 175 Watts (140%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should be 198% faster than the Radeon R9 M295X in general, because of its greater bandwidth. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R9 M295X		176000 MB/sec
	Difference: 348288 (198%)

Texel Rate

The Radeon RX 6900 XT will be quite a bit (about 508%) better at anisotropic filtering than the Radeon R9 M295X. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R9 M295X		96000 Mtexels/sec
	Difference: 488000 (508%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6900 XT is superior to the Radeon R9 M295X, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 209600 (873%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many 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.
