Radeon R9 M295X vs Radeon RX 6500 XT

Intro

Compare all that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core speed at 2200 MHz. The GDDR6 memory works at a frequency of 2250 MHz on this card. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon R9 M295X		125 Watts
	Difference: 18 Watts (17%)

Memory Bandwidth

In theory, the Radeon R9 M295X should be 19% faster than the Radeon RX 6500 XT overall, due to its higher bandwidth. (explain)

Radeon R9 M295X		176000 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 28544 (19%)

Texel Rate

The Radeon RX 6500 XT should be much (approximately 47%) faster with regards to texture filtering than the Radeon R9 M295X. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R9 M295X		96000 Mtexels/sec
	Difference: 44800 (47%)

Pixel Rate

The Radeon RX 6500 XT will be quite a bit (approximately 193%) faster with regards to full screen anti-aliasing than the Radeon R9 M295X, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 46400 (193%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
