Compare any two graphics cards:
GeForce GTX 260 vs Radeon HD 6450 (OEM)
IntroThe GeForce GTX 260 features a GPU core speed of 576 MHz, and the 896 MB of GDDR3 memory runs at 999 MHz through a 448-bit bus. It also is comprised of 192 Stream Processors, 64 TAUs, and 28 ROPs.
Compare those specs to the Radeon HD 6450 (OEM), which makes use of a 40 nm design. ATi has set the core frequency at 625 MHz. The GDDR3 memory runs at a frequency of 800 MHz on this specific card. It features 160 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 260 is 774% quicker than the Radeon HD 6450 (OEM) overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 260 will be a lot (more or less 637%) faster with regards to texture filtering than the Radeon HD 6450 (OEM). (explain)
Pixel RateThe GeForce GTX 260 is much (approximately 545%) faster with regards to full screen anti-aliasing than the Radeon HD 6450 (OEM), and will be capable of handling higher screen 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 maximum amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
