GeForce GTX 460		86400 MB/sec
	Difference: 89600 (104%)

Texel Rate

The Radeon R9 M295X will be quite a bit (approximately 154%) more effective at anisotropic filtering than the GeForce GTX 460. (explain)

Radeon R9 M295X		96000 Mtexels/sec
GeForce GTX 460		37800 Mtexels/sec
	Difference: 58200 (154%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M295X is a better choice, and very much so. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 7800 (48%)

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 (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
