Compare any two graphics cards:
GeForce 9500 GT 1GB GDDR3 vs Radeon HD 6570 (OEM) 2GB
IntroThe GeForce 9500 GT 1GB GDDR3 features a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 128-bit memory bus, and uses a 55 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare that to the Radeon HD 6570 (OEM) 2GB, which has clock speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 480 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the Radeon HD 6570 (OEM) 2GB should in theory be a lot superior to the GeForce 9500 GT 1GB GDDR3 overall. (explain)
Texel RateThe Radeon HD 6570 (OEM) 2GB will be a lot (more or less 77%) more effective at texture filtering than the GeForce 9500 GT 1GB GDDR3. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6570 (OEM) 2GB is a better choice, though only just barely. (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 largest amount of information (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to 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 ability to get to the max fill rate.
