Compare any two graphics cards:
GeForce GTX 1050 vs GeForce GTX 260 216SP 55 nm
IntroThe GeForce GTX 1050 features a GPU core speed of 1354 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1750 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 32 Raster Operation Units.
Compare all that to the GeForce GTX 260 216SP 55 nm, which comes with a core clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also features a 448-bit bus, and uses a 55 nm design. It is comprised of 216 SPUs, 72 Texture Address Units, and 28 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 1050 should in theory be a little bit superior to the GeForce GTX 260 216SP 55 nm in general. (explain)
Texel RateThe GeForce GTX 1050 is much (more or less 31%) faster with regards to AF than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateThe GeForce GTX 1050 will be much (approximately 169%) faster with regards to FSAA than the GeForce GTX 260 216SP 55 nm, and able to handle higher resolutions without losing too much performance. (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 (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount 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 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 graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
