Compare any two graphics cards:
GeForce GTX 650 Ti 2GB vs Radeon HD 7770
IntroThe GeForce GTX 650 Ti 2GB makes use of a 28 nm design. nVidia has clocked the core frequency at 928 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this particular card. It features 768 SPUs along with 64 TAUs and 16 ROPs.
Compare those specs to the Radeon HD 7770, which has core speeds of 1000 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 650 Ti 2GB, in theory, should be just a bit faster than the Radeon HD 7770 overall. (explain)
Texel RateThe GeForce GTX 650 Ti 2GB is quite a bit (approximately 48%) better at AF than the Radeon HD 7770. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 7770 is superior to the GeForce GTX 650 Ti 2GB, but not by far. (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.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many 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.
