GeForce 8500 GT		12800 MB/sec
	Difference: 91200 (713%)

Texel Rate

The Radeon R7 360 is quite a bit (more or less 1300%) more effective at AF than the GeForce 8500 GT. (explain)

Radeon R7 360		50400 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 46800 (1300%)

Pixel Rate

The Radeon R7 360 is quite a bit (approximately 833%) faster with regards to full screen anti-aliasing than the GeForce 8500 GT, and able to handle higher screen resolutions while still performing well. (explain)

Radeon R7 360		16800 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 15000 (833%)

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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
