GeForce GTX 460 1GB vs Radeon RX 460

Intro

The GeForce GTX 460 1GB has a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Compare all that to the Radeon RX 460, which has GPU core speed of 1090 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Radeon RX 460 112000 MB/sec
Difference: 3200 (3%)

Texel Rate

The Radeon RX 460 should be quite a bit (more or less 61%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 460 1GB 37800 Mtexels/sec
Difference: 23240 (61%)

Pixel Rate

The GeForce GTX 460 1GB should be quite a bit (approximately 24%) more effective at anti-aliasing than the Radeon RX 460, and should be able to handle higher screen resolutions better. (explain)

GeForce GTX 460 1GB 21600 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 4160 (24%)

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 largest 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 card's bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
