Compare any two graphics cards:
GeForce 8500 GT vs Radeon R7 M260
IntroThe GeForce 8500 GT has core clock speeds of 450 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 16 SPUs as well as 8 TAUs and 4 ROPs.
Compare those specifications to the Radeon R7 M260, which features a core clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit memory bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.
Power Usage and Theoretical Benchmarks
Theoretically speaking, the Radeon R7 M260 is 25% faster than the GeForce 8500 GT overall, because of its higher bandwidth. (explain)
Texel RateThe Radeon R7 M260 will be quite a bit (more or less 377%) better at AF than the GeForce 8500 GT. (explain)
Pixel RateThe Radeon R7 M260 will be quite a bit (about 218%) more effective at full screen anti-aliasing than the GeForce 8500 GT, and also will be able to handle higher 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 moved past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
