Compare any two graphics cards:
GeForce GTX 965M vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 965M uses a 28 nm design. nVidia has set the core speed at 944 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 6450 (OEM) 1GB, which comes with a core clock speed of 750 MHz and a GDDR5 memory frequency of 900 MHz. It also uses a 64-bit memory bus, and makes use of a 40 nm design. It is comprised of 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 965M should theoretically be a lot superior to the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 965M should be a lot (about 907%) better at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 965M is a lot (more or less 907%) faster with regards to full screen anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and also 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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units 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 number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
