Compare any two graphics cards:
GeForce GTS 450 vs Radeon HD 6450 (OEM) 1GB
IntroThe GeForce GTS 450 features a GPU core speed of 783 MHz, and the 512 MB of GDDR5 memory is set to run at 902 MHz through a 128-bit bus. It also features 192 SPUs, 32 TAUs, and 16 ROPs.
Compare those specifications to the Radeon HD 6450 (OEM) 1GB, which features GPU core speed of 750 MHz, and 1024 MB of GDDR5 memory set to run at 900 MHz through a 64-bit bus. It also is comprised of 160 SPUs, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTS 450 should be a lot faster than the Radeon HD 6450 (OEM) 1GB in general. (explain)
Texel RateThe GeForce GTS 450 will be much (about 318%) faster with regards to texture filtering than the Radeon HD 6450 (OEM) 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 450 is the winner, and very much so. (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 largest amount of data (measured in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the ability to reach the max fill rate.
