Compare any two graphics cards:
GeForce 8400 GS 512MB vs GeForce GTX 1060 3GB
IntroThe GeForce 8400 GS 512MB features a GPU core speed of 650 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 64-bit bus. It also is made up of 16 Stream Processors, 8 TAUs, and 4 ROPs.
Compare all that to the GeForce GTX 1060 3GB, which has a core clock frequency of 1506 MHz and a GDDR5 memory frequency of 2000 MHz. It also uses a 192-bit memory bus, and uses a 16 nm design. It features 1152 SPUs, 72 TAUs, and 48 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB, in theory, should be quite a bit faster than the GeForce 8400 GS 512MB overall. (explain)
Texel RateThe GeForce GTX 1060 3GB should be much (approximately 1985%) faster with regards to AF than the GeForce 8400 GS 512MB. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be quite a bit (more or less 2680%) more effective at anti-aliasing than the GeForce 8400 GS 512MB, and will be capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 can be processed in one second. This is calculated by multiplying the total amount of 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 handling 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 record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
