GeForce GTX 880M vs Radeon R7 370 4G

Intro

Compare all of that to the Radeon R7 370 4G, which features GPU core speed of 975 MHz, and 4096 MB of GDDR5 RAM set to run at 1400 MHz through a 256-bit bus. It also features 1024 SPUs, 64 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 4G		110 Watts
GeForce GTX 880M		130 Watts
	Difference: 20 Watts (18%)

Memory Bandwidth

In theory, the Radeon R7 370 4G will be 40% faster than the GeForce GTX 880M in general, due to its greater data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GTX 880M		128000 MB/sec
	Difference: 51200 (40%)

Texel Rate

The GeForce GTX 880M is a lot (more or less 96%) more effective at AF than the Radeon R7 370 4G. (explain)

GeForce GTX 880M		122112 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 59712 (96%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 370 4G is the winner, but not by far. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GTX 880M		30528 Mpixels/sec
	Difference: 672 (2%)

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 max amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
