Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 7770
IntroThe GeForce GTX 965M features core clock speeds of 944 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.Compare those specifications to the Radeon HD 7770, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 7770 should be 13% faster than the GeForce GTX 965M overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 965M is quite a bit (approximately 51%) more effective at anisotropic filtering than the Radeon HD 7770. (explain)
Pixel RateThe GeForce GTX 965M is a lot (about 89%) better at anti-aliasing than the Radeon HD 7770, and capable of handling higher resolutions while still performing well. (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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
