GeForce GTX 650 Ti 2GB vs Radeon R9 M295X

Intro

Compare those specifications to the Radeon R9 M295X, which has a GPU core clock speed of 750 MHz, and 4096 MB of GDDR5 memory running at 1375 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 89600 (104%)

Texel Rate

The Radeon R9 M295X will be much (more or less 62%) more effective at anisotropic filtering than the GeForce GTX 650 Ti 2GB. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
	Difference: 36608 (62%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M295X is a better choice, by far. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 9152 (62%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 maximum fill rate.
