Haswell represents the "tock" in Intel's "tick-tock" development model: "Tocks" represent a redesign of a chip's architecture, while "ticks" concentrate on shrinking the size of its transistors.

As such Haswell chips retain the 22 nanometre process used to make the current generation of processors, but overhauls their design.

One of the key innovations has been to merge the chip's CPU (central processing unit) with its PCH (platform controller hub).

The CPU carries out calculations and program instructions, while the PCH handles input and output including connections to USB peripherals, audio, and storage.

In the current Ivy Bridge design the CPU uses 17 watts and the PCH a further 4 watts, giving a total energy requirement of 21 watts.

But this has been reduced in Haswell.

I'm sure we'll see more about Haswell soon.

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.

Looks like they're focusing on getting this chip in smaller devices such as tablets.

Might be a good chip against ARM, but how well would it perform if we scale it up to desktop levels?
 
Two things I'm interested in Intel chips / systems doing.

1) Instant boot

2) Being "on" when they're "off". ie being able to do backups and minimal processing when they're suspended.

The low wattage thing does interest me from a HTPC / living room PC though. Looking more like Skylake is where that's really at though the last time I gave it a good look.
 
it is kinda funny,billions spent in r&d,all wasted by slapping any old thermal paste on it:eek:

you should atleast be given the option of what paste you want putting on the chip

oh the melodrama

a disappointment for overclockers, but intel build chips to run at stock settings - the stock cooling solution is fine if you run them at stock

even when overclocking - from what I've seen whilst removing the heatspreader to replace the TIM does drop temps it doesn't necessarily improve the amount of OC you get before needing to add worrying amounts of voltage

Really hope the i5 K Haswell doesn't blow my current chip away since it'll be a long time before I upgrade again.

Same here... I catch the 'upgrade bug' quite easily and i've only just recently ordered parts for my partners new PC (Should last her a while). Part of me hopes Haswell goes the way of AMD's FX chips, just so i don't get tempted to spend more money :D (but it's coming from Intel, so i'm sure it will be great!).

Will this finally make it worthwhile upgrading from q9550.....?
Click to expand...

I think even the current Sandy and Ivy i5's are already a worthwhile upgrade from a Q9550 :)
 
Looking forward to hearing some more about these, as long as it's some kind of performance step from the Bridges I'll be happy enough. I can't believe first gen i7 is almost 4 years old now. Not that long ago a 4 year old PC would normally be considered slow but the old i7 920s are still more than enough performance for most people.
