Radeon HD 5770 vs Radeon HD 6770 1GB
Intro
The Radeon HD 5770 comes with a clock frequency of 850 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is comprised of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.Compare those specs to the Radeon HD 6770 1GB, which comes with core clock speeds of 900 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 800 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.

I would recommend the 5770 because benchmarks tend to prefer that one and the card has more bandwith too.

can you crossfire a 5770 with a 6770??
can you crossfire a 5770 with a 6770
Probably not, the cards need to be of at least the same generation. Besides, these two cards are so close you might as well get a second 5770 if you're going to upgrade, save you some hassle.

It's a shame that the new generation improved so low from the previous,with prices rising sky-high.I really think the 6770 should have been better.
which is the best gpu 5770 or 6770?
