Compare any two graphics cards:
GeForce GT 310 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GT 310 comes with clock speeds of 589 MHz on the GPU, and 1000 MHz on the 512 MB of DDR2 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.Compare all that to the Radeon HD 6450 (OEM) 1GB, which comes with a GPU core clock speed of 750 MHz, and 1024 MB of GDDR5 RAM set to run at 900 MHz through a 64-bit bus. It also is made up of 160 Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthTheoretically speaking, the Radeon HD 6450 (OEM) 1GB should be 80% quicker than the GeForce GT 310 in general, because of its greater data rate. (explain)
Texel RateThe Radeon HD 6450 (OEM) 1GB is much (more or less 27%) better at anisotropic filtering than the GeForce GT 310. (explain)
Pixel RateIf using high levels of AA is important to you, then the Radeon HD 6450 (OEM) 1GB is a better choice, by a large margin. (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 information (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
