GeForce GTX 650 Ti vs Radeon R9 M280X

Intro

The GeForce GTX 650 Ti has a GPU clock speed of 928 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1350 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 64 TAUs, and 16 ROPs.

Compare that to the Radeon R9 M280X, which has GPU core speed of 900 MHz, and 4096 MB of GDDR5 RAM running at 1375 MHz through a 128-bit bus. It also features 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 M280X 75 Watts
GeForce GTX 650 Ti 110 Watts
Difference: 35 Watts (47%)

Memory Bandwidth

In theory, the Radeon R9 M280X should be just a bit faster than the GeForce GTX 650 Ti overall. (explain)

Radeon R9 M280X 88000 MB/sec
GeForce GTX 650 Ti 86400 MB/sec
Difference: 1600 (2%)

Texel Rate

The GeForce GTX 650 Ti should be a small bit (more or less 18%) more effective at anisotropic filtering than the Radeon R9 M280X. (explain)

GeForce GTX 650 Ti 59392 Mtexels/sec
Radeon R9 M280X 50400 Mtexels/sec
Difference: 8992 (18%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is a better choice, but not by far. (explain)

GeForce GTX 650 Ti 14848 Mpixels/sec
Radeon R9 M280X 14400 Mpixels/sec
Difference: 448 (3%)

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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
