Compare any two graphics cards:
GeForce 9600 GSO 1.5GB vs GeForce GT 230
IntroThe GeForce 9600 GSO 1.5GB features a clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 192-bit bus, and makes use of a 65 nm design. It features 96 SPUs, 48 Texture Address Units, and 12 Raster Operation Units.
Compare those specifications to the GeForce GT 230, which comes with a GPU core clock speed of 550 MHz, and 1536 MB of DDR3 memory running at 800 MHz through a 192-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)
Texel RateThe GeForce 9600 GSO 1.5GB is a lot (about 200%) faster with regards to anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateThe GeForce 9600 GSO 1.5GB should be quite a bit (more or less 50%) more effective at FSAA than the GeForce GT 230, and capable of handling higher resolutions while still performing well. (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 information (measured in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 that the graphics chip can 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 the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
