Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 1060 3GB
IntroThe GeForce 8600 GT 512MB DDR2 comes with core 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 Texture Address Units and 8 ROPs.
Compare those specs to the GeForce GTX 1060 3GB, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1506 MHz. The GDDR5 memory is set to run at a frequency of 2000 MHz on this particular model. It features 1152 SPUs along with 72 TAUs and 48 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 1060 3GB should theoretically perform a lot faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GTX 1060 3GB is quite a bit (about 1155%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GTX 1060 3GB should be a lot (about 1573%) faster with regards to AA than the GeForce 8600 GT 512MB DDR2, and will be able to handle higher resolutions without slowing down too much. (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 transported across the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
