Compare any two graphics cards:
GeForce GTX 260 Core 216 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTX 260 Core 216 comes with a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 RAM runs at 999 MHz through a 448-bit bus. It also features 216 Stream Processors, 72 TAUs, and 28 Raster Operation Units.
Compare those specs 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 makes use of a 64-bit memory bus, and uses a 40 nm design. It is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 260 Core 216 should perform much faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTX 260 Core 216 should be a lot (about 591%) faster with regards to anisotropic filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 260 Core 216 will be quite a bit (approximately 438%) more effective at AA than the Radeon HD 6450 (OEM) 1GB, and also capable of handling 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 ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
