Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs Radeon RX 6800
IntroThe GeForce 8600 GT 512MB DDR2 uses a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 RAM works at a frequency of 400 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.
Compare those specs to the Radeon RX 6800, which features a clock speed of 1700 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is comprised of 3840 SPUs, 240 Texture Address Units, and 96 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 6800 should in theory be quite a bit better than the GeForce 8600 GT 512MB DDR2 in general. (explain)
Texel RateThe Radeon RX 6800 is a lot (more or less 4622%) faster with regards to anisotropic filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe Radeon RX 6800 will be quite a bit (about 3678%) faster with regards to AA than the GeForce 8600 GT 512MB DDR2, and will be capable of handling higher resolutions more effectively. (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 data (counted in MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
