GeForce 8800 GT 1GB vs GeForce GTS 450

Intro

Compare all of that to the GeForce GTS 450, which has core clock speeds of 783 MHz on the GPU, and 902 MHz on the 512 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTS 450		106 Watts
	Difference: 1 Watts (1%)

Memory Bandwidth

The GeForce GTS 450, in theory, should perform a small bit faster than the GeForce 8800 GT 1GB overall. (explain)

GeForce GTS 450		57728 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 128 (0%)

Texel Rate

The GeForce 8800 GT 1GB will be quite a bit (more or less 34%) better at AF than the GeForce GTS 450. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 8544 (34%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTS 450 is a better choice, by a large margin. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 2928 (31%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 output rate also depends on lots of 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.
