GeForce GTX 870M vs Radeon RX 460 2GB

Intro

The GeForce GTX 870M uses a 28 nm design. nVidia has clocked the core frequency at 941 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this particular model. It features 1344 SPUs along with 112 TAUs and 24 ROPs.

Compare all of that to the Radeon RX 460 2GB, which uses a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

Radeon RX 460 2GB 112000 MB/sec
GeForce GTX 870M 96000 MB/sec
Difference: 16000 (17%)

Texel Rate

The GeForce GTX 870M should be quite a bit (approximately 73%) better at texture filtering than the Radeon RX 460 2GB. (explain)

GeForce GTX 870M 105392 Mtexels/sec
Radeon RX 460 2GB 61040 Mtexels/sec
Difference: 44352 (73%)

Pixel Rate

The GeForce GTX 870M should be quite a bit (approximately 29%) more effective at anti-aliasing than the Radeon RX 460 2GB, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce GTX 870M 22584 Mpixels/sec
Radeon RX 460 2GB 17440 Mpixels/sec
Difference: 5144 (29%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 processed in one second. This figure is worked out 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
