Radeon R7 370 4G vs Radeon R9 M395X

Intro

Compare all of that to the Radeon R9 M395X, which has core speeds of 723 MHz on the GPU, and 1250 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Radeon R7 370 4G		179200 MB/sec
Radeon R9 M395X		160000 MB/sec
	Difference: 19200 (12%)

Texel Rate

The Radeon R9 M395X should be quite a bit (more or less 48%) faster with regards to AF than the Radeon R7 370 4G. (explain)

Radeon R9 M395X		92544 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 30144 (48%)

Pixel Rate

The Radeon R7 370 4G should be much (approximately 35%) more effective at anti-aliasing than the Radeon R9 M395X, and able to handle higher resolutions without losing too much performance. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 8064 (35%)

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 megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
