GeForce GTX 650 Ti vs Radeon R9 M295X

Intro

Compare all that to the Radeon R9 M295X, which has core clock speeds of 750 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

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

Texel Rate

The Radeon R9 M295X should be quite a bit (more or less 62%) better at AF than the GeForce GTX 650 Ti. (explain)

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

Pixel Rate

If using a high resolution 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		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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
