Radeon R9 M375 vs Radeon R9 M395X

Intro

Compare all that to the Radeon R9 M395X, which uses a 28 nm design. AMD has set the core frequency at 723 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this specific card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M395X should be 355% quicker than the Radeon R9 M375 in general, due to its greater bandwidth. (explain)

Radeon R9 M395X		160000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 124800 (355%)

Texel Rate

The Radeon R9 M395X should be much (approximately 128%) more effective at AF than the Radeon R9 M375. (explain)

Radeon R9 M395X		92544 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 51944 (128%)

Pixel Rate

The Radeon R9 M395X is quite a bit (more or less 42%) faster with regards to AA than the Radeon R9 M375, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M395X		23136 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 6896 (42%)

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 (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its 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 the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
