GeForce GTX 980M vs Radeon RX 460


Intro

The GeForce GTX 980M features core clock speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1536 SPUs as well as 96 Texture Address Units and 64 ROPs.

Compare that to the Radeon RX 460, which comes with GPU clock speed of 1090 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon RX 460 112000 MB/sec
Difference: 16000 (14%)

Texel Rate

The GeForce GTX 980M should be much (more or less 63%) faster with regards to texture filtering than the Radeon RX 460. (explain)

GeForce GTX 980M 99648 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 38608 (63%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 980M is a better choice, by far. (explain)

GeForce GTX 980M 66432 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 48992 (281%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
