We've recently recieved XFX's exquisite Black Edition 850W power supply which comes with the 80+ certificat, although we instantly fell for its looks and the modular design. We've been using it for a few days in our test rig and it has proven to be really good, but we'll follow up on that with a separate review.

 

Looking at Futuremark synthetic tests, the HD 5770 manages to hold its ground against the HD 4870, while the HD 5750 can keep up with the HD 4850.

In 3Dmark 06, the HD 5770 manages to outpace the HD 4870, albeit by a tight margin. The HD 5750 mauls the HD 4850 and scores 10 percent higher. The same goes for the HD 4770, AMD's first 40nm GPU.



Moving along to 3Dmark Vantage on Performance settings, the HD 5770 is unable to keep up with the HD 4870, but it still stays close. HD 5750's 20
percent lead over the HD 4850 and HD 4770 melts away.

The trend continues in Vantage High, but the HD 5750 again manages to pull away from the HD 4850 and HD 4770. Once again, the Juniper XT core of the HD 5770 proves quite a match for the RV770-based HD 4870.





In Vantage Extreme, the Juniper cores with a higher transistor count and newer architecture prove they can keep up with previous generation GPUs,
even with a 128-bit bus. The HD 5770 scores X4369, almost the same as an HD 4870. HD 5750 manages to stay ahead of the HD 4850 and HD 4770.
