Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6670 (OEM)
IntroThe GeForce GTX 550 Ti uses a 40 nm design. nVidia has set the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1026 MHz on this particular model. It features 192 SPUs as well as 32 TAUs and 24 ROPs.
Compare those specs to the Radeon HD 6670 (OEM), which comes with core speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 480 SPUs as well as 24 Texture Address Units 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) in general. (explain)
Texel RateThe GeForce GTX 550 Ti is much (more or less 50%) faster with regards to texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce GTX 550 Ti is quite a bit (approximately 238%) faster with regards to full screen anti-aliasing than the Radeon HD 6670 (OEM), and will be capable of handling higher screen resolutions better. (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
