Nasty speeds. Given the price, performance and overclocking, this chip has basically killed any legit reason to buy a 45nm Intel dual core. Im sure ill be attacked by all the rabid fanbois who think the E8400 is the best chip ever.
I'd be curious to see a comparison of temps and voltages between this and the Intel duals. If these consistently hit 4+, it does mostly kill the reasons to buy an E8000 series, but I'm not convinced that they hit 4+ reliably at a reasonable voltage yet.
I'm pretty sure I've seen that the HK/MG that Intel uses at 45nm doesn't stand high(er) voltages well, which would explain the higher spec on AMD's. Though they're both 45nm, their processes are very different right now.
That's why I was unsure, but I'd be curious to see some official spec sheets.
I'd also be curious to see power usage and heat for 4GHz or more for the AMD triples vs the Intel Duos. Even if they can take the 1.5v and more without damage, I'd be surprised if they used as little power as the Intels.
4.319Ghz at 1.65v, 3.8+ghz at 1.55v, 3.6ghz at 1.44v (stock is 1.325) on what he says is a mobo that needs higher volts.
sounds a bit higher than required to overclock the Core2's. i think the cpu can handle it as most cpu's can if you keep them cool but i see short lived motherboards. wouldnt discourage me from doing it though lol
Well I don't think people that overclock their CPU's and have high end video cards worry to much about the power a system would use. Unless it would be alot more like enough to have to get alot larger power supply.
What I"d want to know is how well it would overclock with a Zalman cooler without changing the voltages one bit. I haven't tried overclocking since the Williamette days and all I'd be interested in is getting 3.4 to 3.6 with a nice air cooler.
I'll have to wait on the Phenom II 720 though. My Gigabyte 780G board died on me and I ran out to Fry's and spent money that could have gone to the 720 on a new board with SB750. At least that should overclock well when I do get one.
I agree completely - the dry ice and LN benchmarks are simply...benchmarks for people who want to benchmark cpu's on dry ice or LN.
On the other hand, if you are oc'ing a system to 40% over stock, you sure aren't worrying about a few extra watts - so i dunno why you are so interested in that. Heat is a non-issue from what i've heard. The Phenom II's have such a huge surface area I haven't seen anyone complain about temps yet with air, it's usually running out of volts. From the reports I'm seeing, the most reported wall with 720 BE overclocking is failing to boot windows even with higher voltages that are POST'ing.
It's probably a variety of stuff and it's almost certainly going to improve over time. Of course very few will hit 4.3ghz with a 720 BE, but 3.8 seems to be standardising itself as the marker for what should be expected.
I care about wattage because lower wattage means lower temps and not as hard on the board. It isn't a matter of power bills or anything like that.
I for one am not comfortable with those voltages. Even if AMDs process is a bit better for taking that high a voltage. I worry about the mobo really with that as the mobo also needs to come into play and if it overheats and dies it could take the CPU and everything else with it.
Thats the only reason I am interested in the Core i7 920 even though I want to wait till the 32nms hit. Just because at stock it will hit 3.8GHz and on air which is plenty of power for me.
But still. 4.2GHz on air is much better than Phenom I did. At least makes Phenom II a threat to Core 2 and Core i7 which means I may be able to pick up a leway CPU upgrade (want the Q9650) for even cheaper in May.
