GeForce GTX 650 Ti 2GB vs Radeon R9 M265X

Intro

The GeForce GTX 650 Ti 2GB comes with a GPU core speed of 928 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1350 MHz through a 128-bit bus. It also features 768 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core frequency at 575 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti 2GB should theoretically perform a bit faster than the Radeon R9 M265X overall. (explain)

GeForce GTX 650 Ti 2GB 86400 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be a lot (more or less 158%) better at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 650 Ti 2GB 59392 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 36392 (158%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 650 Ti 2GB is superior to the Radeon R9 M265X, by far. (explain)

GeForce GTX 650 Ti 2GB 14848 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 5648 (61%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
