GeForce 8600 GT 1GB DDR2 vs GeForce GT 130

Intro

The GeForce 8600 GT 1GB DDR2 has a clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 ROPs.

Compare all of that to the GeForce GT 130, which uses a 55 nm design. nVidia has clocked the core speed at 500 MHz. The DDR2 RAM runs at a speed of 250 MHz on this particular card. It features 48 SPUs as well as 24 TAUs and 16 Rasterization Operator Units.

The GeForce 8600 GT 1GB DDR2, in theory, should be a small bit faster than the GeForce GT 130 in general. (explain)

GeForce 8600 GT 1GB DDR2 12800 MB/sec
GeForce GT 130 12000 MB/sec
Difference: 800 (7%)

Texel Rate

The GeForce GT 130 should be a lot (more or less 39%) better at anisotropic filtering than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce GT 130 12000 Mtexels/sec
GeForce 8600 GT 1GB DDR2 8640 Mtexels/sec
Difference: 3360 (39%)

Pixel Rate

The GeForce GT 130 is much (more or less 85%) more effective at full screen anti-aliasing than the GeForce 8600 GT 1GB DDR2, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GT 130 8000 Mpixels/sec
GeForce 8600 GT 1GB DDR2 4320 Mpixels/sec
Difference: 3680 (85%)

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 information (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the 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 write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
