GeForce 8600 GTS vs GeForce GTX 465

Intro

The GeForce 8600 GTS uses a 80 nm design. nVidia has clocked the core frequency at 675 MHz. The GDDR3 RAM works at a frequency of 1000 MHz on this card. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare those specifications to the GeForce GTX 465, which makes use of a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 memory runs at a speed of 802 MHz on this particular card. It features 352 SPUs as well as 44 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GTS 75 Watts
GeForce GTX 465 200 Watts
Difference: 125 Watts (167%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 465 is 221% faster than the GeForce 8600 GTS in general, due to its greater bandwidth. (explain)

GeForce GTX 465 102592 MB/sec
GeForce 8600 GTS 32000 MB/sec
Difference: 70592 (221%)

Texel Rate

The GeForce GTX 465 should be quite a bit (about 147%) more effective at anisotropic filtering than the GeForce 8600 GTS. (explain)

GeForce GTX 465 26708 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 15908 (147%)

Pixel Rate

The GeForce GTX 465 will be a lot (more or less 260%) more effective at AA than the GeForce 8600 GTS, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 465 19424 Mpixels/sec
GeForce 8600 GTS 5400 Mpixels/sec
Difference: 14024 (260%)

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 data (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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