Compare any two graphics cards:
GeForce 8300 GS (OEM) vs GeForce 9600 GSO 1.5GB
IntroThe GeForce 8300 GS (OEM) comes with clock speeds of 450 MHz on the GPU, and 400 MHz on the 128 MB of DDR2 memory. It features 8 SPUs along with 4 Texture Address Units and 2 Rasterization Operator Units.
Compare that to the GeForce 9600 GSO 1.5GB, which features a GPU core clock speed of 550 MHz, and 1536 MB of GDDR3 RAM running at 800 MHz through a 192-bit bus. It also is comprised of 96 SPUs, 48 Texture Address Units, and 12 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce 9600 GSO 1.5GB should theoretically be much better than the GeForce 8300 GS (OEM) overall. (explain)
Texel RateThe GeForce 9600 GSO 1.5GB is quite a bit (more or less 1367%) better at AF than the GeForce 8300 GS (OEM). (explain)
Pixel RateThe GeForce 9600 GSO 1.5GB will be a lot (approximately 633%) more effective at FSAA than the GeForce 8300 GS (OEM), and should be capable of handling higher screen 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 MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
