Radeon R9 M385X vs Radeon R9 M395X

Intro

The Radeon R9 M385X makes use of a 28 nm design. AMD has set the core speed at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this model. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M395X, which has GPU core speed of 723 MHz, and 4096 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Radeon R9 M395X 160000 MB/sec
Radeon R9 M385X 96000 MB/sec
Difference: 64000 (67%)

Texel Rate

The Radeon R9 M395X should be quite a bit (about 50%) better at texture filtering than the Radeon R9 M385X. (explain)

Radeon R9 M395X 92544 Mtexels/sec
Radeon R9 M385X 61600 Mtexels/sec
Difference: 30944 (50%)

Pixel Rate

The Radeon R9 M395X is a lot (about 31%) more effective at AA than the Radeon R9 M385X, and able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M395X 23136 Mpixels/sec
Radeon R9 M385X 17600 Mpixels/sec
Difference: 5536 (31%)

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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number 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 fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
