Compare any two graphics cards:
GeForce 9600 GSO 512MB vs Radeon HD 3850 1GB
IntroThe GeForce 9600 GSO 512MB has core speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 96 SPUs as well as 48 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 3850 1GB, which features core clock speeds of 668 MHz on the GPU, and 828 MHz on the 1024 MB of GDDR3 memory. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce 9600 GSO 512MB is 9% faster than the Radeon HD 3850 1GB in general, due to its higher data rate. (explain)
Texel RateThe GeForce 9600 GSO 512MB will be a lot (about 192%) faster with regards to anisotropic filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateThe Radeon HD 3850 1GB will be a small bit (approximately 3%) better at full screen anti-aliasing than the GeForce 9600 GSO 512MB, and will be capable of handling higher screen 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 max amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses 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 high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
