GeForce 8800 GS vs GeForce GTS 150

Intro

The GeForce 8800 GS features core speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 RAM. It features 96 SPUs as well as 48 TAUs and 12 ROPs.

Compare those specs to the GeForce GTS 150, which features core clock speeds of 740 MHz on the GPU, and 500 MHz on the 1024 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

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

Texel Rate

The GeForce GTS 150 should be a lot (more or less 79%) more effective at texture filtering than the GeForce 8800 GS. (explain)

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

Pixel Rate

The GeForce GTS 150 should be quite a bit (about 79%) more effective at FSAA than the GeForce 8800 GS, and capable of handling higher screen resolutions while still performing well. (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 maximum amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
