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 frequency at 900 MHz. The GDDR5 RAM works at a frequency of 1026 MHz on this particular card. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.
Compare all that to the Radeon HD 6670 (OEM), which has clock 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 TAUs and 8 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 550 Ti is 54% quicker than the Radeon HD 6670 (OEM) in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 550 Ti should be much (approximately 50%) faster with regards to AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce GTX 550 Ti will be a lot (about 238%) better at AA than the Radeon HD 6670 (OEM), and also should be capable of handling 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.
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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card 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 in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
