Compare any two graphics cards:
GeForce GTX 1050 3GB vs Radeon RX 550
IntroThe GeForce GTX 1050 3GB has a core clock speed of 1392 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 96-bit memory bus, and makes use of a 14 nm design. It features 768 SPUs, 48 TAUs, and 24 Raster Operation Units.
Compare those specs to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon RX 550 is 33% faster than the GeForce GTX 1050 3GB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 1050 3GB is quite a bit (about 90%) more effective at anisotropic filtering than the Radeon RX 550. (explain)
Pixel RateThe GeForce GTX 1050 3GB is a lot (more or less 90%) more effective at FSAA than the Radeon RX 550, and will be capable of handling higher resolutions better. (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 information (in units of MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
