***Official Intel Haswell Thread***

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

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.

I think I'll hold out for haswell, Ivy Bridge is nothing to rave about really, SB was good enough as it is!

It depends what you're buying for.
Ivybridge has a much better IMC and IGP and is slightly faster clock for clock.

Memory overclocking is damn good and for mobile usage (e.g. ITX/laptops) it is awesome.

But yes, most on SB will be holding out for Haswell. Unless you have a lot of money it's almost always best to skip a chip.

 

[Yaayuh!]

No-one even semi serious about games would dream of using an IGP.

It depends on what games.
There are a few older games that i still like to play which the HD4000 IGP is more than capable of handling.

 

[Yaayuh!]

As this is still going nicely and has a load of news in it, can mod/admin please change the title of the thread (i'm the OP) to ***Official Intel Haswell Thread***

Thanks

Haswell leak!

[Yaayuh!]

finally going to upgrade from my 3ghz Q6700 to Haswell. It was going to Ivy but the heat issues turned me away.
The chip to get is the 4770K by the sound of it, roll on April-June!

Yep 4770K seems to be the one to go for.

Can't believe how low the TDPs are getting now lol.

 

[Yaayuh!]

Will there ever be any extreme eight core versions ? of IB-E as that would destroy haswell.

I was hoping 8 but seems to be 6 core 12 threads again to keep the tdp down.

 

[Yaayuh!]

6 cores of SB-E or IB-E is more than enough to wollop Haswell.

(providing multicore coding of applications is done nicely)

 

[Yaayuh!]

High-end i7 mobile chips in April : http://www.xbitlabs.com/news/mobile...l_Processors_for_Notebooks_in_April_2013.html

Considering extreme performance provided by Intel Core i7-4930MX, 4900MQ and 4800MQ central processing units and their 47W – 57W thermal design power, it is likely that they will primarily find them homes insider desktop replacement (DTR) laptops as well as all-in-one (AIO) desktops.

The first Intel Core i-series “Haswell” chips will be released in April, 2013; mainstream solutions powered by Haswell micro-architecture will be launched sometimes in Q3 2013, whereas ultra low-power Haswell products are projected to reach the market in Q4 2013.

 

[Yaayuh!]

Basically, so far it looks to be obvious Intel are concentrating on power efficiency and maturing Ivy.

I care not for Haswell, i wanna know what's going on with Ivy-E. That's where the fun is at.

 

[Yaayuh!]

Think I'll be upgrading my 2500k to the top Haswell chip, need HT this time round and may as well go for the best. Is DDR4 memory in the pipleline for the near future?

After Haswell is my guess. DDR4 is available for Intel to develop with.

 

[Yaayuh!]

8+4 Pin CPU power connection?

Well they need to change the colour.

Black & Orange = Cool... then add some blue as well? lol!

 

[Yaayuh!]

Where's the optional 6-pin? Am i blind?
Or have they worded that badly and what they mean is that you can plug in 4 of the 6pins from a PCI-E connector to provide more power to the VRMs?

 

[Yaayuh!]

Preview of Haswell with benchmarks:

http://www.tomshardware.co.uk/core-i7-4770k-haswell-performance,review-32651.html

Looks to be exactly what i was expecting. Slight improvement over IvyBridge but big improvements on the IGP.
Good news for laptop users, meh for desktops.

 

[Yaayuh!]

well i did mention on another post -
if Intel can't put out a great chip in June with at least 16 cores
A chip that is better than the console CPU (PS4, Xbox 3) chips expected a few months after. Not too to much to ask - is it?
I'm ready to buy, still with a Quad 6700. But im looking very, very carefully ats what on offer by the end of the year. This needs to be a very good chip

Not going to happen.
The console chips are custom APUs that work differently to PCs.

 

[Yaayuh!]

What i meant is that you can't compare the two (PC CPUs and Console custom APUs), and it's pointless anywho because they work differently.

 

[Yaayuh!]

The PS4's CPU is running Jaguar cores, jaguar cores are X86 and will be available for consumers.

It's a custom APU based on the Jaguar using GDDR5, which will not be used for desktop.

 

[Yaayuh!]

The jaguar cores will be used for PC's though/Laptops whatnot.
So we can still compare the CPU.

The GPU is some GCN beast, in between a 7850/7870 (But obviously its performance due to efficiency/optimising will be a lot more than a 7850/7870).

So we can compare the sum of its parts, although it's performance will be greater due to optimising etc.

You can compare all you like, but it's still apples and oranges.

 

[Yaayuh!]

I reckon the overclocking options for Haswell in the UEFI's could be a bit to complicated/confusing.

If it's anything like X79 (where straps are concerned, if it does indeed use them) then it will be a walk in the park. Very easy.

 

[Yaayuh!]

I for one am not expecting anything more than 5% increase clock for clock anywho. I am however expecting:

Power savings
Better IMC
Better IGP

That's all that really matters for these CPUs really, especially for Intel.
