GeForce 8500 GT vs Radeon R7 M260

Intro

The GeForce 8500 GT comes with a core clock frequency of 450 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit memory bus, and uses a 80 nm design. It features 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare all of that to the Radeon R7 M260, which features a core clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also uses a 64-bit memory bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

GeForce 8500 GT 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 is much (more or less 377%) faster with regards to AF than the GeForce 8500 GT. (explain)

Radeon R7 M260 17160 Mtexels/sec
GeForce 8500 GT 3600 Mtexels/sec
Difference: 13560 (377%)

Pixel Rate

The Radeon R7 M260 should be a lot (approximately 218%) more effective at anti-aliasing than the GeForce 8500 GT, and will be capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 M260 5720 Mpixels/sec
GeForce 8500 GT 1800 Mpixels/sec
Difference: 3920 (218%)

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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are applied per second. This number is worked out by multiplying the total texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
