Compare any two graphics cards:
GeForce GTX 1050 3GB vs Radeon R7 250X
IntroThe GeForce GTX 1050 3GB makes use of a 14 nm design. nVidia has set the core frequency at 1392 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this particular card. It features 768 SPUs along with 48 TAUs and 24 ROPs.
Compare those specs to the Radeon R7 250X, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 1050 3GB should theoretically be a bit better than the Radeon R7 250X in general. (explain)
Texel RateThe GeForce GTX 1050 3GB will be quite a bit (approximately 67%) faster with regards to texture filtering than the Radeon R7 250X. (explain)
Pixel RateThe GeForce GTX 1050 3GB should be quite a bit (more or less 109%) better at anti-aliasing than the Radeon R7 250X, and will be able to handle higher resolutions more effectively. (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 in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 applied in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
