Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 1060 3GB
IntroThe GeForce 8600 GT 512MB DDR2 features clock speeds of 540 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 1060 3GB, which comes with clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 3072 MB of GDDR5 memory. It features 1152 SPUs as well as 72 Texture Address Units and 48 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB should theoretically be quite a bit faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GTX 1060 3GB is a lot (more or less 1155%) better at AF than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be a lot (approximately 1573%) better at anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also 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 (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core clock 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 per second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
