Compare any two graphics cards:
GeForce 9800 GT 512MB vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce 9800 GT 512MB has core clock speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 112 SPUs along with 56 TAUs and 16 ROPs.
Compare all of that to the Radeon HD 6450 (OEM) 1GB, which comes with core speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 160 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 9800 GT 512MB should theoretically perform quite a bit faster than the Radeon HD 6450 (OEM) 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 512MB will be much (approximately 460%) better at AF than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateThe GeForce 9800 GT 512MB is a lot (approximately 220%) more effective at full screen anti-aliasing than the Radeon HD 6450 (OEM) 1GB, and able to handle 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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
