Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon RX 470 4GB
IntroThe GeForce 8800 GT 512MB comes with a core clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and makes use of a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.
Compare those specs to the Radeon RX 470 4GB, which has GPU clock speed of 926 MHz, and 4096 MB of GDDR5 RAM running at 1650 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 470 4GB should in theory be a lot superior to the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe Radeon RX 470 4GB will be much (more or less 253%) faster with regards to anisotropic filtering than the GeForce 8800 GT 512MB. (explain)
Pixel RateThe Radeon RX 470 4GB will be much (about 209%) more effective at FSAA than the GeForce 8800 GT 512MB, and also able to handle 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 are applied in one second. This figure is worked out by multiplying the total texture units 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 in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
