GeForce 8800 GS vs GeForce GTS 150

Intro

The GeForce 8800 GS makes use of a 65 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM runs at a speed of 800 MHz on this card. It features 96 SPUs as well as 48 Texture Address Units and 12 Rasterization Operator Units.

Compare those specifications to the GeForce GTS 150, which comes with a GPU core clock speed of 740 MHz, and 1024 MB of GDDR3 memory running at 500 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically, the GeForce 8800 GS should perform just a bit faster than the GeForce GTS 150 in general. (explain)

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

Texel Rate

The GeForce GTS 150 should be a lot (approximately 79%) better at anisotropic filtering 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 lots of anti-aliasing is important to you, then the GeForce GTS 150 is superior to the GeForce 8800 GS, by far. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 amount of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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 memory bandwidth is, the lower the ability to get to the max fill rate.
