Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce GTX 1630
IntroThe GeForce 8600 GT 512MB DDR2 has a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 RAM is set to run at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.
Compare those specifications to the GeForce GTX 1630, which has a clock frequency of 1740 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 64-bit memory bus, and uses a 12 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 1630 should perform quite a bit faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce GTX 1630 will be quite a bit (about 544%) better at anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce GTX 1630 will be quite a bit (more or less 544%) more effective at full screen anti-aliasing than the GeForce 8600 GT 512MB DDR2, and capable of handling higher 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 maximum amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics chip could possibly write to its local memory per 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 sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
