Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 4830 512MB
IntroThe GeForce GTX 965M has a GPU core clock speed of 944 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon HD 4830 512MB, which has a core clock frequency of 575 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 55 nm design. It features 640(128x5) SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 965M should be just a bit faster than the Radeon HD 4830 512MB overall. (explain)
Texel RateThe GeForce GTX 965M is quite a bit (about 228%) more effective at anisotropic filtering than the Radeon HD 4830 512MB. (explain)
Pixel RateThe GeForce GTX 965M will be a lot (about 228%) better at AA than the Radeon HD 4830 512MB, 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 maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
