Radeon R9 M395X vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which comes with a core clock frequency of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 64-bit memory bus, and makes use of a 6 nm design. It is made up of 1024 SPUs, 64 TAUs, and 32 ROPs.

Radeon RX 6500 XT		147456 MB/sec
	Difference: 12544 (9%)

Texel Rate

The Radeon RX 6500 XT is a lot (about 52%) better at AF than the Radeon R9 M395X. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R9 M395X		92544 Mtexels/sec
	Difference: 48256 (52%)

Pixel Rate

The Radeon RX 6500 XT is much (more or less 204%) more effective at full screen anti-aliasing than the Radeon R9 M395X, and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 47264 (204%)

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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
