Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 5450
IntroThe GeForce GTX 965M makes use of a 28 nm design. nVidia has clocked the core speed at 944 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.Compare all that to the Radeon HD 5450, which has a clock frequency of 650 MHz and a DDR3 memory frequency of 800 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It features 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 965M should theoretically be quite a bit better than the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce GTX 965M will be much (approximately 1062%) more effective at AF than the Radeon HD 5450. (explain)
Pixel RateThe GeForce GTX 965M should be quite a bit (approximately 1062%) better at full screen anti-aliasing than the Radeon HD 5450, and will be able to handle 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across 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 type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 number of texture units of the card by the core clock speed of the chip. The better this number, 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 number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
