[WCCFtech] AMD Opens The Lid on Zen Architectural Details at Hot Chips - Page 5

post #41 of 60
Are the Zen chips being fabbed at GLOFLO? I wouldn't be surprised if there were some initial leakage problems with the first couple of batches. Guess we'll have to see.

People trolling about the 1000W psu really need to find something constrictive to do with their time.

They must have been low on money at that time, hence they had to use 1000 watts instead of 1600. biggrin.gif

Oh you.

IMO the reason for the bigger PSU was probably because it was simply lying around from a previous demo system.

Come to think of it, it's not that far fetched, that would also explain limited release of Broadwell, I've always suspected AMD was Intel's 'B' team to keep it out of anti-trust law suits

This is OCN, 90% of trolling is likely to be 90% likely to be 90% trolling.

My EVGA is the same way. Unfortunately lots of people THINK they understand how PSU's work as evidenced by the posts above. My 1300 watt PSU's peak efficiency is right around 600 watts and doesn't fall below 90% until 250-275 watts or so.

This isn't the same for all PSU's of course, but I doubt many people buying high power psu's give two squirts about peak efficiency numbers.

Your system idles around 100W. The person said "you actually lose some efficiency from underloading the psu." That statement remains true. I wish you the best of luck as you learn the English language. It is a difficult one to have high proficiency in.

I understand fine. If you read it again you will see the "30%" in the statement, at 30% load my PSU is about 1% from it's peak efficiency. There isn't much we can do about efficiency at idle, but since the power draw is so low it doesn't matter.

My PSU is well matched to my system (was a better match when I had two cards) and runs in it's peak efficiency range when under load.

His EVGA PSU has 88% efficiency at 10% region(johnyguru), this would add like 15W to his power draw...
If 10W matters so much to you, why did you push 4.6@1.3V on your CPU, do you know how much inefficient that is?


edit: updated with better psu tester
