GeForce 8800 GT 1GB vs GeForce GTS 150

Intro

Compare those specs to the GeForce GTS 150, which features a GPU core clock speed of 740 MHz, and 1024 MB of GDDR3 memory set to run at 500 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTS 150		141 Watts
	Difference: 36 Watts (34%)

Memory Bandwidth

Performance-wise, the GeForce 8800 GT 1GB should in theory be quite a bit better than the GeForce GTS 150 overall. (explain)

GeForce 8800 GT 1GB		57600 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 25600 (80%)

Texel Rate

The GeForce GTS 150 should be quite a bit (about 41%) more effective at AF than the GeForce 8800 GT 1GB. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 13760 (41%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTS 150 is a better choice, and very much so. (explain)

GeForce GTS 150		11840 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 2240 (23%)

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 (measured in megabytes per second) that can be transferred past 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 RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
