GeForce GTX 650 Ti 2GB vs Radeon R7 260X

Intro

The GeForce GTX 650 Ti 2GB uses a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory runs at a speed of 1350 MHz on this particular model. It features 768 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Compare that to the Radeon R7 260X, which features clock speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB 110 Watts
Radeon R7 260X 115 Watts
Difference: 5 Watts (5%)

Memory Bandwidth

In theory, the Radeon R7 260X should be just a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)

Radeon R7 260X 104000 MB/sec
GeForce GTX 650 Ti 2GB 86400 MB/sec
Difference: 17600 (20%)

Texel Rate

The Radeon R7 260X will be just a bit (more or less 4%) more effective at texture filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon R7 260X 61600 Mtexels/sec
GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Difference: 2208 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 260X is the winner, but not by far. (explain)

Radeon R7 260X 17600 Mpixels/sec
GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Difference: 2752 (19%)

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 MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 also depends 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.
