Compare any two graphics cards:
GeForce GTX 590 vs Radeon RX 470 4GB
IntroThe GeForce GTX 590 features a core clock frequency of 607 MHz and a GDDR5 memory frequency of 855 MHz. It also makes use of a 384-bit bus, and uses a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 ROPs.
Compare those specs to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory works at a frequency of 1650 MHz on this particular card. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 590 should be 55% faster than the Radeon RX 470 4GB in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon RX 470 4GB should be quite a bit (more or less 53%) better at anisotropic filtering than the GeForce GTX 590. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 590 is superior to the Radeon RX 470 4GB, and very much so. (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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.
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 data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
