Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce GTX 550 Ti comes with a GPU core speed of 900 MHz, and the 1024 MB of GDDR5 memory is set to run at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 TAUs, and 24 Raster Operation Units.
Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific card. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 550 Ti should in theory be much faster than the Radeon HD 6670 (OEM) 1GB overall. (explain)
Texel RateThe GeForce GTX 550 Ti will be much (approximately 50%) more effective at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce GTX 550 Ti should be a lot (approximately 238%) faster with regards to AA than the Radeon HD 6670 (OEM) 1GB, and also should be able to handle higher resolutions without losing too much performance. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most 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 Render Output Units by the the card's clock speed. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
