GeForce 8600 GTS vs GeForce GT 230

Intro

The GeForce 8600 GTS features core speeds of 675 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.

Compare all that to the GeForce GT 230, which comes with a core clock frequency of 550 MHz and a DDR3 memory frequency of 800 MHz. It also makes use of a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 230 65 Watts
GeForce 8600 GTS 75 Watts
Difference: 10 Watts (15%)

Memory Bandwidth

In theory, the GeForce GT 230 should be 20% faster than the GeForce 8600 GTS overall, because of its higher data rate. (explain)

GeForce GT 230 38400 MB/sec
GeForce 8600 GTS 32000 MB/sec
Difference: 6400 (20%)

Texel Rate

The GeForce 8600 GTS is quite a bit (approximately 23%) faster with regards to texture filtering than the GeForce GT 230. (explain)

GeForce 8600 GTS 10800 Mtexels/sec
GeForce GT 230 8800 Mtexels/sec
Difference: 2000 (23%)

Pixel Rate

The GeForce 8600 GTS is quite a bit (about 23%) faster with regards to FSAA than the GeForce GT 230, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 8600 GTS 5400 Mpixels/sec
GeForce GT 230 4400 Mpixels/sec
Difference: 1000 (23%)

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 information (counted in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR RAM, the result should 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
