Compare any two graphics cards:
GeForce GTX 860M vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 860M comes with clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 750 MHz. The GDDR5 memory works at a frequency of 900 MHz on this model. It features 160 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 860M should theoretically be much better than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 860M is much (more or less 1175%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 860M is superior to the Radeon HD 6450 (OEM) 1GB, and very much so. (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 information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied 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 better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
