GeForce GTX 870M vs Radeon R7 M360

Intro

Compare those specifications to the Radeon R7 M360, which makes use of a 28 nm design. AMD has clocked the core speed at 1125 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this specific model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 870M should be 500% quicker than the Radeon R7 M360 in general, because of its greater bandwidth. (explain)

GeForce GTX 870M		96000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The GeForce GTX 870M is a lot (more or less 290%) better at texture filtering than the Radeon R7 M360. (explain)

GeForce GTX 870M		105392 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 78392 (290%)

Pixel Rate

The GeForce GTX 870M is a lot (more or less 151%) more effective at AA than the Radeon R7 M360, and able to handle higher resolutions while still performing well. (explain)

GeForce GTX 870M		22584 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 13584 (151%)

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 information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied in one second. This number is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per 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 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
