GeForce 8500 GT vs Radeon R7 M260

Intro

The GeForce 8500 GT features a GPU clock speed of 450 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is comprised of 16 Stream Processors, 8 Texture Address Units, and 4 ROPs.

Compare those specs to the Radeon R7 M260, which features core speeds of 715 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 M260 should in theory be a lot superior to 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 is much (more or less 377%) more effective at texture filtering 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 high levels of AA is important to you, then the Radeon R7 M260 is a better choice, and very much so. (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 max amount of data (in units of MB per second) that can be transferred 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. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
