GeForce 8600 GTS vs Radeon R7 240

Intro

The GeForce 8600 GTS comes with a clock frequency of 675 MHz and a GDDR3 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the Radeon R7 240, which uses a 28 nm design. AMD has set the core frequency at 730 MHz. The DDR3 RAM is set to run at a frequency of 900 MHz on this card. It features 320 SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

GeForce 8600 GTS 10800 Mtexels/sec
Difference: 3800 (35%)

Pixel Rate

The Radeon R7 240 is a small bit (approximately 8%) faster with regards to full screen anti-aliasing than the GeForce 8600 GTS, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon R7 240 5840 Mpixels/sec
GeForce 8600 GTS 5400 Mpixels/sec
Difference: 440 (8%)

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 (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video 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 that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
