Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 9600 GT 1GB features a core clock speed of 650 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It features 64 SPUs, 32 TAUs, and 16 ROPs.
Compare those specifications to the GeForce GT 430 1GB, which features a GPU core clock speed of 700 MHz, and 1024 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also features 96 SPUs, 16 TAUs, and 4 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce 9600 GT 1GB is 100% quicker than the GeForce GT 430 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce 9600 GT 1GB will be much (approximately 86%) more effective at AF than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce 9600 GT 1GB is a lot (approximately 271%) better at FSAA than the GeForce GT 430 1GB, and also should be capable of handling 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
