Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 6770
IntroThe GeForce GTX 550 Ti features core speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 RAM. It features 192 SPUs along with 32 Texture Address Units and 24 ROPs.Compare that to the Radeon HD 6770, which uses a 40 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 memory runs at a speed of 1050 MHz on this particular card. It features 800 SPUs as well as 40 Texture Address Units and 16 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 550 Ti will be 47% faster than the Radeon HD 6770 in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon HD 6770 will be quite a bit (approximately 25%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti will be much (about 50%) faster with regards to FSAA than the Radeon HD 6770, and should 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 Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

8 Responses to “GeForce GTX 550 Ti vs Radeon HD 6770”The Radeon HD 6770 has memory of 1024 MB not 512, as mentioned in the review.
There's a separate 1GB version.
That's true
I gb gddr5 version is available for Ati radeon hd 6770
Nvidia geforce 550 ti requires Pci-e 2.0 not 2.1
i want to know wheather 550ti in compaitable wth dual core processor . my mothebord's model is ASUS-P5KPL-AM-PS please help me
the 1 gb version of the 6770 has a core speed of 850 mhz
i just returned my radeon HD 6770 1GB and its core speed was 775 and 1000 im getting the 550 TI and its clocked for 950 and 4355
550ti is prefarable
