Radeon R9 M295X vs Radeon R9 M390X

Intro

The Radeon R9 M295X features a GPU core speed of 750 MHz, and the 4096 MB of GDDR5 RAM is set to run at 1375 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Compare those specs to the Radeon R9 M390X, which features core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon R9 M295X will be 10% quicker than the Radeon R9 M390X in general, due to its higher bandwidth. (explain)

Radeon R9 M295X 176000 MB/sec
Radeon R9 M390X 160000 MB/sec
Difference: 16000 (10%)

Texel Rate

The Radeon R9 M295X is a bit (about 4%) faster with regards to AF than the Radeon R9 M390X. (explain)

Radeon R9 M295X 96000 Mtexels/sec
Radeon R9 M390X 92544 Mtexels/sec
Difference: 3456 (4%)

Pixel Rate

The Radeon R9 M295X should be a bit (more or less 4%) more effective at AA than the Radeon R9 M390X, and should be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 M295X 24000 Mpixels/sec
Radeon R9 M390X 23136 Mpixels/sec
Difference: 864 (4%)

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: Bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
