I really need to upgrade my PC, I'm still on the first gen Core i7 -- I have the 965 EE -- as well as a Radeon HD 4870 X2 because I built this PC in late 2008; and still no SSDs. When I have the money to upgrade, everything is getting an upgrade!

I would like Maximum PC to contact Intel, & find out WHY CPUs can't seem to get past 3.8 GHZ without users manually overclocking them. We should at LEAST be up to 4.5GHZ without OC by now.

The answer is pretty straight forward. Power consumption. "Back in the day" which wasn't that long ago. They were hitting 4.x GHz and power consumption was raising just as fast if not faster than clock speed. Heat and cooling were becoming major problems as well. So they added cores, used smaller dies, added threads and focused on ways to increase CPU performance without also increasing clock speed and sucking up more and more power and creating more heat. At first old CPU's would outrun newer ones since software didn't take advantage of the extra cores and such.

Fast-forward to today. Clock speed have inched up again to about where they left off while at the same time boosting efficiency and CPU power. Most software can now take advantage of multiple cores (maybe not 8 but 4 simply enough).

It's not a bad compromise at this point but there was some pain to get here.

The base speed of a chip is NOT a good indication of how well it performs. You have to have lived thru the MHz wars to understand that clock speed does not mean what it used to. AMD for instance has some CPU chips that have high GHZ clocks but are easily beaten in benchmarks and real world applications by a much less "speedy" Intel chip.

I think both architecture improvements and an increase in GHZ is not an unreasonable thing to ask for. In the next few years I foresee the GHZ mark being an important selling point again - even more so when processors start using photons instead of electrons (in the more distant future of course!).

On another forum, they found the the voltages for Haswell weren't displayed correctly on CPU-Z; it displayed the voltage of... something else, I forgot. Anyway, thank you for wasting your time!

I don't know about the incorrect voltage reporting theory Noshei. According to screen shot 1 he's running .896 to hit 4800. At 3.8 he was using a voltage of .719. So to hit 5 Ghz at .904 seems pretty plausible. And if that's the case, then Haswell should be a wet dream for overclockers everywhere with a liquid cooling solution...

the other screenshots on that forums make your assertions look a little... unbalanced. He's had to go to 4GB RAM on a single DIMM to get the 5GHz OC. And just because the Haswell chip will run on low voltage doesn't mean it's going to run on higher. If the stock vcore has been lowered, what then?

Still gonna wait until steamroller shows up to decide, but this is awesome.

Dammit, Intel's Haswell chip, Samsung's 256GB Pro SSD, and NVidia's 770 GPU are all singing the siren song of "TIME TO UPGRADE!" again. Oh yeah, that sweet Dell 30" monitor too. My builds don't need to be upgraded but...

Do you upgrade everything else in your life as soon as there is a new model out? how about your car? I find it to be an even more satisfying of a feeling when I skip a generation between upgrades. At least then you can actually feel the difference between them :-)

10% rule. If there is not a 10% boost in speed, size, or coolness, no upgrade.

If Haswell does overclock much better than Ivy Bridge, then perhaps.

The SSD is a go as I have a upgrade path for 3 other people's computers for bumping along older SSD's.

I always wanted to upgrade to Big Kepler (settled of a pair of 680s instead for my son and I when Big Kepler was a no show) but Titan is too damn expensive.

30" monitor with the same resolution as my 27"? That will probably be a pass until the price comes down.

He's not happy unless his WEI is 10.0 across the board =)

How do you measure a 10% increase in coolness?

avatar

John Pombrio

I measure PC peripherals coolness with a thermometer. Held against a new case, mouse, keyboard, or printer ad, it tells me what next to buy. For instance, the Corsiar Vengence K90 keyboard was 17% cooler than my old MS 4000 so I bought it. Same with the Corsair graphite series 6000 case, 23% cooler than my old case.

Sarcasm John? I hope?

So this is most likely not actually what happened on the computer. I'm not saying that the images are fake or anything. What is more likely is that CPUz is reporting an incorrect voltage. This i known to happen with new processors.
