Compare any two graphics cards:
GeForce GTX 1050 3GB vs Radeon R9 M270X
IntroThe GeForce GTX 1050 3GB makes use of a 14 nm design. nVidia has clocked the core frequency at 1392 MHz. The GDDR5 memory is set to run at a frequency of 1750 MHz on this particular model. It features 768 SPUs along with 48 TAUs and 24 ROPs.
Compare those specifications to the Radeon R9 M270X, which features a clock speed of 725 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Theoretically, the GeForce GTX 1050 3GB should be just a bit faster than the Radeon R9 M270X in general. (explain)
Texel RateThe GeForce GTX 1050 3GB will be much (approximately 130%) more effective at anisotropic filtering than the Radeon R9 M270X. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 1050 3GB is superior to the Radeon R9 M270X, 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.
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 (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
