Compare any two graphics cards:
GeForce GTX 1050 vs GeForce GTX 275
IntroThe GeForce GTX 1050 uses a 14 nm design. nVidia has clocked the core frequency at 1354 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 32 Rasterization Operator Units.
Compare those specs to the GeForce GTX 275, which makes use of a 55 nm design. nVidia has set the core frequency at 633 MHz. The GDDR3 RAM is set to run at a frequency of 1134 MHz on this specific model. It features 240 SPUs along with 80 Texture Address Units and 28 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 275 should theoretically be a little bit better than the GeForce GTX 1050 overall. (explain)
Texel RateThe GeForce GTX 1050 will be a bit (about 7%) better at AF than the GeForce GTX 275. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 1050 is superior to the GeForce GTX 275, 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: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core 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 processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
