Compare any two graphics cards:
GeForce GTX Titan vs Geforce GTX 780
IntroThe GeForce GTX Titan comes with 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 Texture Address Units, and 48 Raster Operation Units.
Compare all of that to the Geforce GTX 780, which makes use of a 28 nm design. nVidia has set the core speed at 863 MHz. The GDDR5 RAM is set to run at a speed of 1502 MHz on this specific card. It features 2304 SPUs along with 192 TAUs and 48 Rasterization Operator Units.
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 perform the same. (explain)
Texel RateThe GeForce GTX Titan should be a small bit (approximately 13%) better at texture filtering than the Geforce GTX 780. (explain)
Pixel RateThe Geforce GTX 780 should be a small bit (about 3%) faster with regards to FSAA than the GeForce GTX Titan, and capable of handling higher screen 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 (measured in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, 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 anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
