VS

GeForce GTX 560 vs Radeon RX 480 4GB

Intro

The GeForce GTX 560 comes with core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

Compare those specs to the Radeon RX 480 4GB, which comes with a clock speed of 1120 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the Radeon RX 480 4GB should in theory be a lot superior to the GeForce GTX 560 in general. (explain)

Radeon RX 480 4GB 229376 MB/sec
GeForce GTX 560 128128 MB/sec
Difference: 101248 (79%)

Texel Rate

The Radeon RX 480 4GB will be much (more or less 256%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)

Radeon RX 480 4GB 161280 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 115920 (256%)

Pixel Rate

The Radeon RX 480 4GB should be a lot (approximately 38%) more effective at FSAA than the GeForce GTX 560, and will be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 480 4GB 35840 Mpixels/sec
GeForce GTX 560 25920 Mpixels/sec
Difference: 9920 (38%)

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 (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
