Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GTS 450
IntroThe GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this particular model. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.
Compare all of that to the GeForce GTS 450, which features core speeds of 783 MHz on the GPU, and 902 MHz on the 512 MB of GDDR5 memory. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTS 450 will be 0% quicker than the GeForce 9600 GT 1GB in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTS 450 is a little bit (about 20%) faster with regards to anisotropic filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe GeForce GTS 450 is just a bit (more or less 20%) faster with regards to AA than the GeForce 9600 GT 1GB, and capable of handling higher resolutions more effectively. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
