Compare any two graphics cards:
GeForce GTX 1050 3GB vs GeForce GTX 970M
IntroThe GeForce GTX 1050 3GB comes with core clock speeds of 1392 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 RAM. It features 768 SPUs along with 48 TAUs and 24 Rasterization Operator Units.
Compare that to the GeForce GTX 970M, which features GPU clock speed of 924 MHz, and 3072 MB of GDDR5 memory set to run at 1000 MHz through a 192-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 48 Raster Operation Units.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
The GeForce GTX 970M, in theory, should perform a little bit faster than the GeForce GTX 1050 3GB overall. (explain)
Texel RateThe GeForce GTX 970M should be a little bit (more or less 11%) faster with regards to anisotropic filtering than the GeForce GTX 1050 3GB. (explain)
Pixel RateThe GeForce GTX 970M will be a lot (about 33%) better at anti-aliasing than the GeForce GTX 1050 3GB, and also will be capable of handling higher screen 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 maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
