Compare any two graphics cards:
Nvidia Titan X vs Radeon R9 295X2
IntroThe Nvidia Titan X makes use of a 16 nm design. nVidia has set the core speed at 1417 MHz. The GDDR5X memory is set to run at a speed of 1251 MHz on this particular card. It features 3584 SPUs as well as 224 Texture Address Units and 96 ROPs.
Compare those specs to the Radeon R9 295X2, which uses a 28 nm design. AMD has clocked the core speed at 1018 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this specific card. It features 2816 SPUs as well as 176 Texture Address Units and 64 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon R9 295X2 should theoretically be much superior to the Nvidia Titan X in general. (explain)
Texel RateThe Radeon R9 295X2 is a small bit (about 13%) more effective at anisotropic filtering than the Nvidia Titan X. (explain)
Pixel RateThe Nvidia Titan X is a little bit (more or less 4%) more effective at AA than the Radeon R9 295X2, and should 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.
One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.
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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
