GeForce GTX 560 Ti vs Radeon RX 460

Intro

The GeForce GTX 560 Ti features clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

Compare that to the Radeon RX 460, which has a clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit bus, and uses a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 75 Watts
GeForce GTX 560 Ti 170 Watts
Difference: 95 Watts (127%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti should be a small bit faster than the Radeon RX 460 overall. (explain)

GeForce GTX 560 Ti 128256 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 16256 (15%)

Texel Rate

The Radeon RX 460 is just a bit (about 16%) faster with regards to AF than the GeForce GTX 560 Ti. (explain)

Radeon RX 460 61040 Mtexels/sec
GeForce GTX 560 Ti 52608 Mtexels/sec
Difference: 8432 (16%)

Pixel Rate

The GeForce GTX 560 Ti should be a lot (more or less 51%) more effective at AA than the Radeon RX 460, and should be able to handle higher resolutions better. (explain)

GeForce GTX 560 Ti 26304 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 8864 (51%)

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 (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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 max fill rate.
