GeForce GTX 295 vs Radeon RX 460

Intro

The GeForce GTX 295 has a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 ROPs.

Compare all of that to the Radeon RX 460, which features a GPU core clock speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 Raster Operation Units.

Radeon RX 460 112000 MB/sec
Difference: 111776 (100%)

Texel Rate

The GeForce GTX 295 should be much (about 51%) more effective at anisotropic filtering than the Radeon RX 460. (explain)

GeForce GTX 295 92160 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 31120 (51%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 295 is the winner, by a large margin. (explain)

GeForce GTX 295 32256 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 14816 (85%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at 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 could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
