GeForce GTX 650 Ti vs Radeon RX 460 2GB

Intro

The GeForce GTX 650 Ti has a core clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon RX 460 2GB, which makes use of a 14 nm design. AMD has set the core frequency at 1090 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 460 2GB 75 Watts
GeForce GTX 650 Ti 110 Watts
Difference: 35 Watts (47%)

Memory Bandwidth

The Radeon RX 460 2GB, in theory, should perform quite a bit faster than the GeForce GTX 650 Ti overall. (explain)

Radeon RX 460 2GB 112000 MB/sec
GeForce GTX 650 Ti 86400 MB/sec
Difference: 25600 (30%)

Texel Rate

The Radeon RX 460 2GB should be a small bit (more or less 3%) faster with regards to texture filtering than the GeForce GTX 650 Ti. (explain)

Radeon RX 460 2GB 61040 Mtexels/sec
GeForce GTX 650 Ti 59392 Mtexels/sec
Difference: 1648 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 460 2GB is a better choice, but not by far. (explain)

Radeon RX 460 2GB 17440 Mpixels/sec
GeForce GTX 650 Ti 14848 Mpixels/sec
Difference: 2592 (17%)

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 data (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
