Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 780
IntroThe GeForce GTX Titan has a GPU core clock speed of 837 MHz, and the 6144 MB of GDDR5 RAM is set to run at 1502 MHz through a 384-bit bus. It also is comprised of 2688 Stream Processors, 224 TAUs, and 48 ROPs.
Compare those specs to the Geforce GTX 780, which features a GPU core clock speed of 863 MHz, and 3072 MB of GDDR5 RAM set to run at 1502 MHz through a 384-bit bus. It also is made up of 2304 Stream Processors, 192 Texture Address Units, and 48 ROPs.
BenchmarksThese are real-world performance benchmarks that were submitted by Hardware Compare users. The scores seen here are the average of all benchmarks submitted for each respective test and hardware.
3DMark Fire Strike
Grand Theft Auto V | 1920x1080 | Very High
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Both cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce GTX Titan should be a little bit (more or less 13%) better at texture filtering than the Geforce GTX 780. (explain)
Pixel RateThe Geforce GTX 780 is just a bit (approximately 3%) more effective at anti-aliasing than the GeForce GTX Titan, and also will be able to handle higher screen 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 (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 maximum fill rate.
