Compare any two graphics cards:
GeForce GTX 285 1GB vs Radeon HD 6450 (OEM)
IntroThe GeForce GTX 285 1GB features clock speeds of 648 MHz on the GPU, and 1242 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.Compare all of that to the Radeon HD 6450 (OEM), which has a clock speed of 625 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 64-bit memory bus, and uses a 40 nm design. It is made up of 160 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 285 1GB should perform quite a bit faster than the Radeon HD 6450 (OEM) overall. (explain)
Texel RateThe GeForce GTX 285 1GB is a lot (about 937%) more effective at texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce GTX 285 1GB is much (approximately 729%) faster with regards to FSAA than the Radeon HD 6450 (OEM), and also should 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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
