Radeon R7 370 4G vs Radeon R9 M370X

Intro

Compare those specifications to the Radeon R9 M370X, which has a core clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Theoretically speaking, the Radeon R7 370 4G will be 149% quicker than the Radeon R9 M370X overall, because of its greater data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 107200 (149%)

Texel Rate

The Radeon R7 370 4G will be a lot (more or less 95%) more effective at AF than the Radeon R9 M370X. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 30400 (95%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 370 4G is a better choice, by a large margin. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 18400 (144%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
