GeForce 8500 GT vs Radeon R7 M260

Intro

The GeForce 8500 GT comes with a GPU core clock speed of 450 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is made up of 16 SPUs, 8 TAUs, and 4 ROPs.

Compare those specs to the Radeon R7 M260, which features a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260 should in theory be quite a bit better than the GeForce 8500 GT overall. (explain)

Radeon R7 M260 16000 MB/sec
GeForce 8500 GT 12800 MB/sec
Difference: 3200 (25%)

Texel Rate

The Radeon R7 M260 will be a lot (approximately 377%) more effective at AF than the GeForce 8500 GT. (explain)

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

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R7 M260 is a better choice, by far. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
