Fresh out of Intel Developer Forum 2013 (Beijing), we have some good info about Haswell's overclockability via Anandtech.  Some highlights:

• Looks like BClk overclocking is back, and memory frequencies are going to scale up to 2933 from the factory (more with BClk overclocking).  
• Voltage regulators being on the CPU package mean overclockers now only need to adjust 2 voltages when overclocking, logic and DRAM.  Should simplify things quite a bit!  
• Max overclocking headroom without using BClk is 8GHz.  Yes, 8GHz.  Of course this doesn't mean anyone who isn't using LN2 or similar will ever hit that, but maybe there's more headroom for those of us that still use "traditional" positive ambient cooling such as air or water.

Not too much news there since it's been known already about BCLK and onboard voltage regulators.  It will be great to hear something empirical, or at least about whether or not the TIM was replaced w/ a better solution.  They do seem to be trying to appeal to the enthusiast market some though which is helpful--since the rest of development is aimed towards low power & integrated graphics.

The specifics are new, though.  Upper multiplier of 80 allowing for 8GHz maximum CPU clock without touching BClk, upper memory limit of 2933MHz (again without touching BClk).

I just hope that this is a great overclocker on air and they do not use tim, but use solder.  I want to upgrade to Haswell, but I also want to get close to get to 5.0GHz on air (or at least close) and do that without have to pop the top and replace the tim .

You and me both, though I hope with water to hit much higher than 5GHz.  I also hope the early preview benchmark results that indicate lower IPC prove to be wrong, at least for FSX or I'll have no reason to upgrade.  

Good news, I'd like to see FSX on 8GHz....  :Thinking:

Sounds very promising. How different would FSX be on HASWELL + GTX TItan

and HASWELL + GTX 580 all other things being equal? A thousand Dollars worth different?

Intel seems to be moving away from the desktop motherboard business (they claim by 2016) a worrying proposition. I built 3 AMD based rigs before moving to Intel. Will continue to follow the new Haswell chip with great interest. A 6+ Ghz CPU married with a Titan. I can dream can't I!

Wow... that would be something else!

We're in an interesting place now as desktops have really moved steadily away from anything but specialty applications and the business environment though the portability of laptops has encroached there too. And moreover, the business use of desktops is very largely not related to high performance. Besides FSX, I wonder what other modern software cares about Ghz. I sense the days of higher and higher clockspeeds is coming to an end fast as more modern software is increasingly designed to take advantage of multi-core, multi-processor, multi-threading, where smart design can be leveraged.

 

Be fun to try loading up XPlane 64-bit on dual Xeon E5-2687W in a dual socket main board (turbo clocks to 3.9, that's it since multipliers are locked down). Here's one guy's report on his:

 

 

Decimates Cinema 4D / Adobe CS Workloads

 

Pros: 16 physical cores (2-Socket WS Mobo) and 128GB of RAM take your productivity to entirely new levels. If your workstation is a *tool* and not a toy, these 8-core E5 CPUs decimate even the vaunted 3960X 6-core units by an order of magnitude in C4D and AE/Premiere. If you're a video and/or 3D motion graphics pro, just get two of these via any means possible -- sell blood, superfluous appendages, excess children, or whatever you need to do to get these. You'll make enough back in productivity gains to buy them back later.

You'll pay around $4K for two of these bad boys! Boy I'd like to go there!

Listen, the stone age didn't end because we ran out of stone and the age of the modern desktop PC is going to be all over very soon. But who cares? As enthusiast we may NEVER again see the next level. from what I have read P3D V 2.0 may or may not be FSX 12, but who cares! As far as I am concerned more powerful hardware is were its at. creative cooling, Overclocking, 5+ ghz maybe 6ghz or higher, 4th gen intel, plus 8 or 16 gigs of fast RAM plus GTX titan or better or even worse on 64 bit OS and we have arrived at the maxed out and liquid fluid FSX. It is going to happen sooner or later. beyond that I don't know what anyone else wants? better weather engine etc. Go fly a real airplane!

I remember when FSX was released the BS marketing line was the Hardware to run this software hasn't been invented yet! Well now we are on the brink of the hardware to run this software has been invented. Now go enjoy your hobby and discus with your therapist how you have nothing to complain about. It is all but over. Enjoy getting used to the new reality by the end of 2013!

I am really wanting to move towards smarter, multiprocessor, multicore, multithreaded where total processing is shared maximally in a parallel environment.   Amping up voltage, increasing cooling requirements, potentially sensitive timings seem crude compared to leveraging using these various multi/parallel processing design.  I would love to see how dual Xeon E5-2687W 8x core processors @3.8Ghz would run something like XPlane 64--and throw in Dual Titan GTXs (XPlane version 10.10 doesn't support SLI) and 64Gb of decent quad-channel ram and XPlane 64-bit would be so easy for that machine to handle I would imagine.  FSX?  Well, not so much!

That's all very well and good for Laminar research and fans of X-plane 10 but for fans of FSX those technologies are never going to be available unless Lockheed Martin delivers them in P3D V2.0 or above. That may never happen, in which cause we FSX fans will just have to build dedicated systems with choice best hardware available at the time we build. My point is that the day is coming when we will be able to have a maxed out fluid FSX experience because the overclocked hardware will be able to deliver it. We are never going to have SLI or multi-threading or a worthwhile return on more than 6 cores or 16 gigs of ram. This is the objective reality that we FSX fans have to live with. When will this change? Only when and if Lockheed Martin releases P3D V 2.0 or later. FSX fans are never going to make the move to X-plane in Droves. Just not going to happen!

I strongly disagree, but this opinion is based on third party developers moving to XPlane, and this remains unsure at this time. This is the sensible pathway because then, and only then, will future hardware development (increasing parallelism) be in sync w/ software leaving lots of headroom for future development. Supercomputers are based on this, not whipping a few cores into a frenzy. And of course, the software programs running on supercomputers are designed to exploit this. FSX will forever be stuck in this, and getting to 6Ghz for example, a stretch unless something gives in a big way, is only going to get you another 20% over 5Ghz. Think how long it's been since meaningful increases in overclocking have occurred. 3-5 years? When you load up the NGX at KSEA w/ all sliders right in PNW scenery and you're seeing 21FPS, you will get to a whopping 27fps. That is good enough I would admit, but that becomes the end of the line for increasing complexity. You will never be able to get to high resolution close up ground textures for example at 6Ghz, only w/ spreading the processing load over 6, 8, 16 cores, etc. Maybe P3D will offload enough to the GPU to add some more complexity and depth--we'll see.

BCLK 125 to produce ddr3-3000MHz.....sweet!
