GeForce GTX 460 2GB vs Radeon RX 460


Intro

The GeForce GTX 460 2GB comes with a GPU core clock speed of 675 MHz, and the 2048 MB of GDDR5 memory runs at 900 MHz through a 256-bit bus. It also is made up of 336 SPUs, 56 TAUs, and 32 ROPs.

Compare those specifications to the Radeon RX 460, which uses a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 896 SPUs along with 56 Texture Address Units and 16 ROPs.

The Radeon RX 460 will be much (about 61%) more effective at AF than the GeForce GTX 460 2GB. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 23240 (61%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 460 2GB is superior to the Radeon RX 460, by a large margin. (explain)

GeForce GTX 460 2GB 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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once 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 is worked out by multiplying the total number of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 output 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 max fill rate.
