Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GTS 450 1GB
IntroThe GeForce 9600 GT 1GB uses a 65/55 nm design. nVidia has set the core speed at 650 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular model. It features 64 SPUs as well as 32 Texture Address Units and 16 ROPs.
Compare those specs to the GeForce GTS 450 1GB, which features GPU core speed of 783 MHz, and 1024 MB of GDDR5 memory running at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTS 450 1GB is 0% faster than the GeForce 9600 GT 1GB in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTS 450 1GB will be a bit (more or less 20%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe GeForce GTS 450 1GB is a small bit (more or less 20%) more effective at FSAA than the GeForce 9600 GT 1GB, and also able to handle higher resolutions better. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
