Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 1060 3GB
IntroThe GeForce 8600 GT 512MB DDR2 features a GPU clock speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.
Compare those specs to the GeForce GTX 1060 3GB, which has a GPU core clock speed of 1506 MHz, and 3072 MB of GDDR5 RAM running at 2000 MHz through a 192-bit bus. It also features 1152 Stream Processors, 72 TAUs, and 48 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 1060 3GB should in theory be much better than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe GeForce GTX 1060 3GB should be much (more or less 1155%) faster with regards to AF than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be much (approximately 1573%) more effective at anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also able to handle 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 information (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
