GeForce 8600 GT 1GB GDDR3 vs GeForce GT 315

Intro

The GeForce 8600 GT 1GB GDDR3 has a GPU clock speed of 540 MHz, and the 1024 MB of GDDR3 memory runs at 700 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.

Compare all of that to the GeForce GT 315, which features a GPU core clock speed of 625 MHz, and 512 MB of DDR3 RAM set to run at 790 MHz through a 128-bit bus. It also is comprised of 48 Stream Processors, 16 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB GDDR3 47 Watts
GeForce GT 315 52 Watts
Difference: 5 Watts (11%)

Memory Bandwidth

Performance-wise, the GeForce GT 315 should theoretically be a little bit superior to the GeForce 8600 GT 1GB GDDR3 overall. (explain)

GeForce GT 315 25280 MB/sec
GeForce 8600 GT 1GB GDDR3 22400 MB/sec
Difference: 2880 (13%)

Texel Rate

The GeForce GT 315 is a little bit (approximately 16%) more effective at texture filtering than the GeForce 8600 GT 1GB GDDR3. (explain)

GeForce GT 315 10000 Mtexels/sec
GeForce 8600 GT 1GB GDDR3 8640 Mtexels/sec
Difference: 1360 (16%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 315 is the winner, though not by far. (explain)

GeForce GT 315 5000 Mpixels/sec
GeForce 8600 GT 1GB GDDR3 4320 Mpixels/sec
Difference: 680 (16%)

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 (measured in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
