***Official Intel Haswell Thread***

I don't think that graph is right it should use a lot less than ivy,esp at idle

could be the higher clocked igpu that's bumping up the wattage? idk if it was tested using the igpu or not?

Overclocking

BitTech said:
Turning our attention to our shiny new Core i7-4770K, we started by cranking up the multiplier to see how far we got without touching any other settings. We eventually hit a wall at 4.4GHz with the PC throwing a BSOD at us at 4.5GHz as soon as we entered Windows. However it seemed perfectly stable at 4.4GHz, which is very similar to what you'd expect from an Ivy Bridge CPU.

From here, though, the temperatures increased rapidly and we reached our limit of 4.7GHz using 1.257V and a scorching temperature of 98°C, and that's using a Corsair H100i, which we know to offer the best cooling short of a custom water-cooling kit. The jury is out on why this might be - the 22nm manufacturing process is clearly going to add a lot of heat density, as we saw with Ivy Bridge, but like Ivy Bridge, there's the issue of thermal paste vs solder too.

Despite most of the voltage regulation being moved on-package, motherboards still expose all of the same voltage controls that you’re used to from previous platforms. Haswell’s FIVR does increase the thermal footprint of the chip itself, which is why TDPs went up from 77W to 84W at the high-end for LGA-1150 SKUs. Combine higher temperatures under the heatspreader with a more mobile focused chip design, and overclocking is going to depend on yield and luck of the draw more than it has in the past.

Haswell doesn’t change the overclocking limits put in place with Sandy Bridge. All CPUs are frequency locked, however K-series parts ship fully unlocked. A new addition is the ability to adjust BCLK to one of three pre-defined straps (100/125/167MHz). The BCLK adjustment gives you a little more flexibility when overclocking, but you still need a K-SKU to take advantage of the options.

In terms of overclocking success on standard air cooling you should expect anywhere from 4.3GHz - 4.7GHz at somewhere in the 1.2 - 1.35V range. At the higher end of that spectrum you need to be sure to invest in a good cooler as you’re more likely to bump into thermal limits if you’re running on stable settings.

surprised the TTL review didn't go into BLCK clocking

normally like TTL's reviews - but this one - not sure - comparing power draw to a 2011 system ? and one with 6 cores - seemed a bit irrelevant
 
Although I am looking quite far in the future, I am wondering if Skylake would follow the same pattern of small bump in cpu performance coupled with few extra features.
 
wow, the 4770k is making my i7 920 look very average now. I think I'll be upgrading :)

I am in the same boat as you. For overclocking the 3960K is better. Or even the 3770K.

The 4770k is undoubtedly faster than the 3770k on a clock per clock basis, however our 3770k sample overclocks quite easily to 5ghz and runs cooler than the 4770k engineering sample that Intel sent us. At 5ghz the 3770k will clearly outclass the 4.5ghz 4770k in a variety of duties.

This makes it a little difficult for us to recommend that everyone head online and spend a lot of money moving to the new 4770k, especially if your 3770k runs cool and overclocks to 4.8ghz – 5ghz without hassle. We have spoken to several system builders in the United Kingdom this week and they tell us that they will be not pushing their 4770k systems past 4.4ghz and they may even aim closer to 4.2ghz..
 
It doesnt matter if i go 3930k or 4770k, ideally im after a high quality mobo for overclocks etc that has as few GPU slots as possble.
If new power states arn't supported by desktop haswells why are PSUs being rated as haswell compatible?
 
Looks like its a very 'meh' refresh. However this iris pro thing sounds interesting, despite it being bga only. Could shake the notebook market up a little at least...

Whilst the odds are extremenly against AMD it would be quite amusing if steamroller turned out to be amazing as it would be 10 years since they last pulled off that stunt with the athlon 64 vs p4!
