[ChinaDIY]The default fully loaded breaking 100 ° C i7-4770K retail air-cooled overclocking experience - Page 16

It's because they want to control VRM losses more tightly on laptops since laptops already a 1.8-2.5V power source for the VRM directly currently
That's why the VRM is 1.8-2.5V operation because Haswell is built ground-up
Keep in mind Haswell was already in dev when Nehalem came out ...

Clearly already working on new Tock after Sandy Bridge
Can you guess what that is? Haswell. They wanted to lower power consumption at that point for laptops.
We all know why AMD failed with BD, it was because of the darn CEO who thinks lower power consumption and higher IPC is not right and forsaking mobile platforms on top of that
Rushing things left and right ... but anyway.

But being on OCN i don't give a darn about power savings

i remember a post i had written in another thread...

i'm reading all these comments about people in this thread and others complaining about power consumption in GPU's and CPU's and it irks me. This is OCN, and overkill is a standard for most of us. I feel like its contradictory to have someone with 2,3 GPU's and water cooling loops to compare AMD/Nvidia GPU's or AMD/Intel CPU's for power consumption.... really?

in regards to this actual thread, people were raving about ivy power consumption and turns out it runs hotter when overclocked due to the TIM. I'd recommend you guys to hold those power consumption comparisons back until we see overclocked temperatures of Haswell, unless you guys love getting hyped up and crushed in disappointment later.

just my two cents, im not singling anyone out, it just baffles me and I personally believe that to the 95% of us it doesn't matter. i dont have statistics, but i feel like the majority of OCN falls under the "3-gpu" people. We might not own 3 GPU's and power-hungry rigs, but we certainly want one if the budget was available.

i personally am very happy with my i5-2500k. i haven't overcloked it yet and it has been running the stuff i need it to just fine. i'll upgrade AFTER applications become so heavy that a 4.6 OC doesn't cut it anymore. and based off what i'm doing (non-crysis gaming), that upgrade should come a generation after haswell or late 2014-2015, whichever comes first.

so far ive heard that there's no OC improvement at all. I was told that out of 10 chips only 1 could hit 4.8ghz. ive also been told that ivy is actually the better chip over haswell? guess its all unreliable till the retail silicone hits the stores?

intel have been focusing way to much on power consumption! but I guess that's where the markets at?

the z87 chipset & new instruction sets looks a little better though. don't think anyone cares about the Igpu lol?

I for 1 don't care about how many watts it eats lol. the more the better imo lol ?

looks like ivy-E for me still. unless those rumours of them skipping it is true?

basically Sandy seems to be the last holy grail. even Ivy's temperatures have been higher, but on the flipside they preform better clock for clock. so thats fair. we have to see where haswell falls in the scheme of things.

I just hope there is another Sandy coming down the line at some point. My 2600K really seemed like something special when I got it in early 2011 but none of the subsequent releases have seemed significant from a performance standpoint (SB-E was also really cool simply because they didn't worry about power consumption or iGPU but its still SB IMO). Would love to see Intel try to build an ultimate performance chip again, power consumption be damned....
