Compare any two graphics cards:
GeForce GTX 880M vs Radeon RX 460
IntroThe GeForce GTX 880M uses a 28 nm design. nVidia has clocked the core frequency at 954 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this card. It features 1536 SPUs along with 128 Texture Address Units and 32 Rasterization Operator Units.
Compare those specifications to the Radeon RX 460, which features a clock speed of 1090 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit bus, and makes use of a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 880M should theoretically be just a bit superior to the Radeon RX 460 overall. (explain)
Texel RateThe GeForce GTX 880M should be much (approximately 100%) faster with regards to AF than the Radeon RX 460. (explain)
Pixel RateThe GeForce GTX 880M should be much (more or less 75%) faster with regards to FSAA than the Radeon RX 460, and will be capable of handling higher resolutions without slowing down too much. (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 max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should 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 anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. 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 get to the max fill rate.
