Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs GeForce GTS 250 1GB
IntroThe GeForce 8800 GTS (G80) 640MB uses a 90 nm design. nVidia has set the core speed at 513 MHz. The GDDR3 RAM works at a speed of 792 MHz on this model. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.Compare those specifications to the GeForce GTS 250 1GB, which has a GPU core clock speed of 738 MHz, and 1024 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 250 1GB will be 11% quicker than the GeForce 8800 GTS (G80) 640MB overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTS 250 1GB is a lot (about 92%) more effective at AF than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTS 250 1GB is a better choice, though only just barely. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many 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.

2 Responses to “GeForce 8800 GTS (G80) 640MB vs GeForce GTS 250 1GB”I like this post n I want to buy the Geforce GTS 250 1GB buh u dont actually show the prizes from amazone at all, u only show prizes on different items altogether. So check on that pls
That's Amazon's fault, nothing I can do about it.
