Radeon R9 M370X vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which has GPU core speed of 1015 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon R9 M375X is quite a bit (approximately 27%) more effective at AF than the Radeon R9 M370X. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 8600 (27%)

Pixel Rate

The Radeon R9 M375X will be much (approximately 27%) more effective at AA than the Radeon R9 M370X, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 3440 (27%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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.
