VS

Radeon R9 M375 vs Radeon RX 6900 XT

Intro

The Radeon R9 M375 has core clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 6900 XT should be 1389% quicker than the Radeon R9 M375 overall, due to its higher data rate. (explain)

Radeon RX 6900 XT 524288 MB/sec
Radeon R9 M375 35200 MB/sec
Difference: 489088 (1389%)

Texel Rate

The Radeon RX 6900 XT will be a lot (more or less 1338%) better at texture filtering than the Radeon R9 M375. (explain)

Radeon RX 6900 XT 584000 Mtexels/sec
Radeon R9 M375 40600 Mtexels/sec
Difference: 543400 (1338%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is the winner, and very much so. (explain)

Radeon RX 6900 XT 233600 Mpixels/sec
Radeon R9 M375 16240 Mpixels/sec
Difference: 217360 (1338%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
