is 5 ghz the new 4ghz? -Sandy Bridge - Page 4

post #31 of 75
What are the benefits of having 4.5GHz for a home user like me? My work is computer related but I do it does not require the latest and fastest CPU. I am a casual gamer. Sure, I get a huge e-penis but in terms of performance?

Things feel more snappy, if you want to reduce it to what you absolutely need, an atom processor is fine for mostpeople

Could a stable 50Ghz allow me to run RR7 at FULL speed with no slowdowns? God I hope so!

I can't help but believe these new 32nm chips will be even more delicate, and yet these review sites are pumping 1.5v+ through them and posting high clock speeds.
This is not a coincidence. If you want to understand more you can read about it here http://www.overclockingwiki.org/inde...iquid_nitrogen

I can say with confidence that the safe threshold for these chips is likely to be below 1.4V, possibly even < 1.35V based on Intel's specs. Electron migration becomes a big problem as the manufacturing process shrinks which also directly implies lower tolerance to voltage.

In one sentence, do not expect to be able to run these chips for 24/7 pumping 1.5V through them (IMHO even 1.4V is ambitious for 24/7). This is likely a publicity stunt to differentiate the SB chips from LGA1156/LGA1366 in order to boost sales. It's actually laughable how many of these early reviews do not compare chips clock-for-clock yet they claim performance boost. Of course you get more performance with higher clock on the same basic architecture.

Edit: you can actually refer to i7 970 and i7 980x overclocking to see that it supports what I am saying. They are both manufactured using the 32nm process and are both (while very good clockers) less voltage tolerant for 24/7. The biggest difference is and will be power consumption, clock for clock. 32nm chips are just more efficient overall.

32nm i7-900 series datasheet seen here lists MAX Vcc at 1.4V. Expect i7-2x00 to be the same.

2.8ghz is pretty good for me most of the time
I don't think that 5ghz will ever be equal to 4ghz...

Boo, I absolutely cannot work on an Atom; the Atom is a joke. The minimum I need is an Athlon K8 single core at around 2200Mhz which would be about 2-3x as fast (I've tested myself, I find that I really cannot web browse smoothly and satisfyingly enough with anything lower)

That said, 4.5Ghz probably won't bring a very noticeable benefit considering evne 4Ghz on most (older but still) modern chips is fast enough.
post #40 of 75
I dunno about using the 980x 32nm as a base to suggestion voltages.


I mean can you show me the 980x running 1.6 on air? Yah more cores, can you show me the i3 or i5 running 1.6 on air benchmarking?

All those are 32nm, none of them are doing what this chip has done.

We'll have to once again, wait to see.... one more day isn't it?
