Compare any two graphics cards:
GeForce GTX 1050 3GB vs GeForce GTX 970M
IntroThe GeForce GTX 1050 3GB features core clock speeds of 1392 MHz on the GPU, and 1750 MHz on the 3072 MB of GDDR5 memory. It features 768 SPUs along with 48 TAUs and 24 ROPs.
Compare all of that to the GeForce GTX 970M, which comes with a clock frequency of 924 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 48 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
As far as performance goes, the GeForce GTX 970M should in theory be a little bit superior to the GeForce GTX 1050 3GB overall. (explain)
Texel RateThe GeForce GTX 970M is a little bit (about 11%) better at anisotropic filtering than the GeForce GTX 1050 3GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 970M is a better choice, by a large margin. (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 data (counted in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
