Compare any two graphics cards:
GeForce GTX 960M vs Radeon HD 4850 2GB
IntroThe GeForce GTX 960M uses a 28 nm design. nVidia has set the core speed at 1096 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the Radeon HD 4850 2GB, which makes use of a 55 nm design. AMD has clocked the core frequency at 625 MHz. The GDDR4 RAM works at a speed of 993 MHz on this model. It features 800(160x5) SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 960M should in theory be a little bit better than the Radeon HD 4850 2GB in general. (explain)
Texel RateThe GeForce GTX 960M is quite a bit (more or less 75%) better at texture filtering than the Radeon HD 4850 2GB. (explain)
Pixel RateThe GeForce GTX 960M is much (more or less 75%) better at FSAA than the Radeon HD 4850 2GB, and should be able to handle higher screen resolutions without losing too much performance. (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 largest amount of data (measured in megabytes per second) that can be transferred 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 the card has DDR RAM, 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 AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
