GeForce GTX 870M vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which comes with core clock speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 870M will be 33% faster than the Radeon R9 M370X overall, due to its higher data rate. (explain)

GeForce GTX 870M		96000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 24000 (33%)

Texel Rate

The GeForce GTX 870M is much (approximately 229%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce GTX 870M		105392 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 73392 (229%)

Pixel Rate

The GeForce GTX 870M is quite a bit (about 76%) better at AA than the Radeon R9 M370X, and also able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 870M		22584 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 9784 (76%)

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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
