VS

GeForce GTX 970M vs Radeon RX 460 2GB

Intro

The GeForce GTX 970M features a clock speed of 924 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 192-bit memory bus, and makes use of a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 48 Raster Operation Units.

Compare all of that to the Radeon RX 460 2GB, which has GPU core speed of 1090 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 460 2GB should in theory perform a small bit faster than the GeForce GTX 970M overall. (explain)

Radeon RX 460 2GB 112000 MB/sec
GeForce GTX 970M 96000 MB/sec
Difference: 16000 (17%)

Texel Rate

The GeForce GTX 970M will be quite a bit (about 21%) faster with regards to AF than the Radeon RX 460 2GB. (explain)

GeForce GTX 970M 73920 Mtexels/sec
Radeon RX 460 2GB 61040 Mtexels/sec
Difference: 12880 (21%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 970M is a better choice, and very much so. (explain)

GeForce GTX 970M 44352 Mpixels/sec
Radeon RX 460 2GB 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. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few 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.
