GeForce GTX 970M vs Radeon RX 460


Intro

The GeForce GTX 970M uses a 28 nm design. nVidia has set the core speed at 924 MHz. The GDDR5 memory works at a speed of 1000 MHz on this particular model. It features 1280 SPUs along with 80 Texture Address Units and 48 ROPs.

Compare all that to the Radeon RX 460, which features a GPU core clock speed of 1090 MHz, and 4096 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also features 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 460, in theory, should be a bit faster than the GeForce GTX 970M in general. (explain)

Radeon RX 460 112000 MB/sec
GeForce GTX 970M 96000 MB/sec
Difference: 16000 (17%)

Texel Rate

The GeForce GTX 970M is quite a bit (more or less 21%) more effective at AF than the Radeon RX 460. (explain)

GeForce GTX 970M 73920 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 12880 (21%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 970M is superior to the Radeon RX 460, by a large margin. (explain)

GeForce GTX 970M 44352 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 26912 (154%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
