Compare any two graphics cards:
GeForce GTX 1660 Ti vs GeForce GTX 590
IntroThe GeForce GTX 1660 Ti features core clock speeds of 1500 MHz on the GPU, and 12000 MHz on the 6144 MB of GDDR6 RAM. It features 1536 SPUs along with 96 TAUs and 48 Rasterization Operator Units.
Compare all that to the GeForce GTX 590, which has a clock speed 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 is made up of 512 SPUs, 64 TAUs, and 48 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 590, in theory, should be a small bit faster than the GeForce GTX 1660 Ti in general. (explain)
Texel RateThe GeForce GTX 1660 Ti will be much (approximately 85%) more effective at AF than the GeForce GTX 590. (explain)
Pixel RateThe GeForce GTX 1660 Ti will be a lot (approximately 24%) more effective at AA than the GeForce GTX 590, 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.
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: Bandwidth is the max amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
