Compare any two graphics cards:
GeForce 8600 GS (OEM) vs Radeon HD 5450
IntroThe GeForce 8600 GS (OEM) uses a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this model. It features 32 SPUs along with 16 TAUs and 8 ROPs.
Compare those specs to the Radeon HD 5450, which has a clock frequency of 650 MHz and a DDR3 memory speed of 800 MHz. It also features a 64-bit bus, and makes use of a 40 nm design. It is comprised of 80(16x5) SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)
Texel RateThe GeForce 8600 GS (OEM) should be quite a bit (more or less 66%) faster with regards to texture filtering than the Radeon HD 5450. (explain)
Pixel RateThe GeForce 8600 GS (OEM) will be much (approximately 66%) more effective at full screen anti-aliasing than the Radeon HD 5450, and also able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
