Looks like it is about a 20% increase in performance over SandyBridge and a 10% increase over Ivy Bridge. - If these prove to OC to 5GHZ then I will build a new Haswell rig at release! :biggrin:

How is that possible with FSX when clock speeds are the same?

 

I would like to see the CPU clock to 5.5 to 6.0 in order for me to consider upgrading.

Because the architecture of the CPU changes with each release, as technology improves they can change the design to make the processor more effective.

I think you'll be waiting for some time. Intel seemed to have stopped chasing clock speeds some time ago concentrating instead on efficiency. AMD still seem to be chasing clock speed because they can't match Intels design but even so they are still behind.

Looks as thought the AMD Pile driver may have caught up or getting close with Intel.

I'll wait for some more detailed info about overclocking before I make my decision, but I have a love of shiny new hardware so I know I'm going to want to upgrade when Haswell comes out.

 

Either way my next full system build is going to be an interesting one for me since it will be first foray into real water cooling.

The only relevent article I can see on that link states that that the Unlocked 6 core 6300 Piledriver at 3.5Ghz is unable to compete against the locked dual core 3225 at 3.3Ghz in the autors gaming tests until he overclocks the AMD chip. At 5Ghz he makes a nebulous statement that "it’s actually encroaching on the territory of the i5-3570K" and I'm going to assume he means a 3570K that isn't overclocked which effectively makes the comparison worthless. One of his last statements is "I’m not recommending anyone rethink their purchase of an i5 for their rig build". Is this the relevent article?

I agree that it CAN make the processor more effective, but does this really apply to FSX? I don't think that a CPU alone will help FSX's performance. I look at CPU OC speed, RAM speed, and the GPU.  I might add an SSD to the equattion since IMO dramatically improves performance loading.

 

When I said 5.5 to 6.0, I meant a chip that will allow us to easily OC to that speed on water or good air cooler. I wished that Intel would have stuck with Sandy Bridge. A few more Sandy Bridge upgrades would have put us there.

It's Tom's so I'll take it with a grain of salt but those memory bandwidth and single thread benchmarks are not very promising. If Haswell has lower memory performance and IPC than Ivy Bridge, it's going to have to out-clock it to be faster in FSX.

I'm with you, Jose: the SB - particularly the 2700K - is a great chip for overclocking, not suffering the heat issues of the IB, while doing it very simply and predictably, and with a moderate vCore.

Going to have to wait on the Graphene semiconductor based technology. Graphene allows tighter packing of transistors with minimal heat dissipation. Current silicon CPU technology has hit the thermal dynamic wall. Graphene is not far off.

What about the USB 3.0 bug? I heard certain devices could switch off after restarting from hibernate.

Graphene as a replacement for silicon is still a long way off.  Microprocessor manufacturers have roadmaps looking years off into the future and there's no sign of graphene on them.  We've just hit the 22nm node and Intel, IBM, Samsung, Global Foundries, and TSMC all have plans for nodes < 10nm (read: at least 2 generations off).  Given that there are at least 2-3 years in between generations, we've got perhaps a decade or more before anyone even thinks of switching to graphene.

All I gots is time. Not wasting it on replacing CPU's just because their NEW! I have two brand new Sandy Bridges setting here in a boxes. they'll do me until a new very improved technology arrives. Not 10% 20 maybe etc marketing schemes of Ivy Bridge,hackwell, Hesheys Chocolate etc. Good for investors yes. Good for performance? Not so much.

You state the above as though Intel engineers are intentionally holding back.  What you seem not to realize is that from a design standpoint, all of the "low hanging fruit" has already been picked.  Each new CPU is going to bring with it incremental improvements from here on out unless we get better software tools for devs to take advantage of multi-threading.  

 

I'm glad you like your Sandy Bridge(s), I like my Ivy Bridge also and will likely not play the guinea pig this time around in testing Haswell at launch.  If the pre-release benchmark results are correct and Haswell is regressing memory and single-thread performance, it will need to be a monster overclocker to out-perform my current chip at 4.9GHz in FSX.  

Interesting to see the stated thermal ceiling to be 84 watts even with a 7 to 13% increase in performance over the I7-3770K
