To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Crysis Warhead and record the results.
In such an energy aware climate, AMD are making a big deal out of their new ‘ZeroCore Power’ technology. Many solutions today use power gating, clock gating and memory compression to reduce idle power requirements, but ZeroCore power technology can completely power down the core GPU while the rest of the system remains active.
The R7770 Power Edition demands 65 watts at the slot when under gaming load. This rises to around 80 watts under Furmark load. There is no doubt the R7770 is an efficient design from AMD.
Dont get it… you either want a single fan card, or a dual fan card…so just buy a single fan card, or a dual fan card- there are better dual fan coolers out there, such as XFXs Brushed Aluminium cooler, looks a thousand times better than the neon blue plastic tat on this card… Its not like your going to put this in your system and suddenly wake up one day and say- ‘i know i fancy two fans today’….
I get your point, although I think its cool you can basically change the noise/cooling balance to suit different environments. size too.
If it cost £30 more then its pretty pointless, but it seems closely priced to the other HD7770s.
Still think sapphire HD6850 was the best deal for a while at £90.
Great motherboard but im not sure on the graphics card. its clever, but for the target market im not sure its a buying decision. You either want a smaller card for a media center, or a higher cooled, size card for gaming.
Gamers wont buy the HD7770 I wouldnt think, so why not just put a larger single fan on the HD7770 in the first place and ditch the extra fan completely?
Nice idea to be creative like this, but ultimately I think its a bit pointless.
Ok, first thing first. this motherboard is from what I know the same as the GD65 but now has thunderbolt. its a great board. all we need to say (apart from the added price for thunderbolt).
The graphics card is frigging cool. The shiftable cooler idea is nice. Its maybe only useful for people who change systems regularly. so you could ditch a fan, slot it into a HPTC, then take it out, extend it then add another etc.
How many people would do that though? Might make more sense on a HD7850 or 7870. HD7770 is more suited just for media duties and low powered use.
please put two hd7770 in crossfire the results will show that they can deliver more fps
than the high end gtx 670 and hd 7870
with lots of money left over get that new motherboard
give it try
