GeForce 8800 GS vs GeForce GTS 150

Intro

The GeForce 8800 GS comes with a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also makes use of a 192-bit bus, and makes use of a 65 nm design. It is made up of 96 SPUs, 48 TAUs, and 12 Raster Operation Units.

Compare all that to the GeForce GTS 150, which has a clock speed of 740 MHz and a GDDR3 memory speed of 500 MHz. It also features a 256-bit bus, and uses a 55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Power Consumption (Max TDP)

GeForce 8800 GS 105 Watts
GeForce GTS 150 141 Watts
Difference: 36 Watts (34%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GS should be 20% faster than the GeForce GTS 150 in general, due to its greater bandwidth. (explain)

GeForce 8800 GS 38400 MB/sec
GeForce GTS 150 32000 MB/sec
Difference: 6400 (20%)

Texel Rate

The GeForce GTS 150 will be quite a bit (more or less 79%) better at AF than the GeForce 8800 GS. (explain)

GeForce GTS 150 47360 Mtexels/sec
GeForce 8800 GS 26400 Mtexels/sec
Difference: 20960 (79%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTS 150 is a better choice, by a large margin. (explain)

GeForce GTS 150 11840 Mpixels/sec
GeForce 8800 GS 6600 Mpixels/sec
Difference: 5240 (79%)

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 moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
