Compare any two graphics cards:
GeForce GT 320 vs Radeon HD 6570 (OEM) 1GB
IntroThe GeForce GT 320 comes with core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 memory. It features 72 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 6570 (OEM) 1GB, which makes use of a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR3 memory works at a speed of 900 MHz on this particular card. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6570 (OEM) 1GB will be 14% quicker than the GeForce GT 320 in general, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6570 (OEM) 1GB should be a small bit (more or less 20%) faster with regards to texture filtering than the GeForce GT 320. (explain)
Pixel RateThe Radeon HD 6570 (OEM) 1GB is a little bit (approximately 20%) more effective at anti-aliasing than the GeForce GT 320, and capable of handling higher resolutions more effectively. (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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If 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 higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
