GeForce 8500 GT vs Radeon R7 M260

Intro

The GeForce 8500 GT uses a 80 nm design. nVidia has set the core speed at 450 MHz. The DDR2 RAM runs at a frequency of 400 MHz on this particular model. It features 16 SPUs as well as 8 TAUs and 4 ROPs.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 M260 will be 25% quicker than the GeForce 8500 GT in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon R7 M260 is a lot (approximately 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 quite a bit (more or less 218%) more effective at full screen anti-aliasing than the GeForce 8500 GT, and also should be able to handle 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
