Hi guys ,

 

i 've been reading the forums for a long time tried to make a decision for a new system ( current system see signature ) but simply can 't decide to go for a i7 3770k ivy or a i7 3820 sb-e , both on a asus rampage iv formula ( 3820 ) or a asus maximus v formula (3770k)

I know there is a little price difference in processors , the sb-e is cheaper but the mothernoard costs more ,

 

There are a lot of threads about the 33770k , a lot of help but i can't find anything about the 3820 , how is this sb-e based system compared to the ivy system , they can oc about the same ,( i saw some oc results for the 3820 up to 5.0 ghz) , is the ivy "better " then the sb-e , or simply cheaper .

 

I read a lot about the difference in oc , heat issues but it is all about the ivy , can someone help me with this ?

 

Thanks in advance ,

 

 

Best regards ,

 

Gérard

SB-E chips are quite more expensive where I am -- and the price-to-performance ratio for the unlocked (K) or extreme (X) models just isn't there when compared to the new IB chips, or the regular SB's, in my opinion.

 

If money is no concern, then it comes down to what kind of temps do you feel comfortable running. :)

Gerard,

 

You've got a lot more horsepower than I'm using, and I still have a wonderful time w/ FSX. Why not wait for another generation, Haswell, which *may* turn out to be a better over clocker than IB by some early guesses. I can't imagine your satisfaction level will improve appreciably w/ an upgrade at this time...

Hi ,

A 3770k ivy chip is about 30 euros more then a 3820 sb-e while the asus formula mothernoard in sb-e socket is about 30 euros more then the 1155 socket formula v so the price combo processor - motherboard is about the same 600 for ivy and 609 euros for sb-e so there is almost no price difference ,

I thought that the SB-E supports multi-threaded (quad channel) memory access, but FSX like most software does not support multi-threaded memory access, so a plain SB (IB) with dual channel DDR3 RAM will nearly always out perform the Quad channel variant. Iwould go for the fastest IB/SB cpu that runs on dual channel DDR3 RAM.

Just an opinion.

This. SB-E is really a waste of money unless you run 3-4 graphics cards, which is of no benefit to flight sim.

multi-threaded (quad channel) memory access

 

Aren't you mixing terminology?

 

Threads refer to a sequence of instructions... whereas "channel" refers to bandwidth based on memory clockrate.

 

To my knowledge... there is no "IB quad channel variant".

Well... we have yet to see someone push an i7-3820 with some fast quad channel mem and high spec components (SSD / GTX680 etc.) so it seems to me speculation.

 

@Gérard

 

I have been wondering the same myself... I think I am leaning IB since it is "newer" technology and hoping with something like Corsair Platinum (2666 or 3000) mem that should be sufficient (hoping... no way of actually knowing until trying). Fast SSD & at least one 680 if not the 690 (I'd like to run 2 @ 2560x1440).

 

Edit: One good thing... we have a nice "safety net" >the FSXMark11 Benchmark test results< that show it would be hard to go wrong with a 3770k spec'd well.

The SB-E's are made for heavy threaded loads which fsx does qualify imo. Im planning on building round the 3930K 6 core cpu. With my current i7-960 i have noticed that i can run at 30% cpu load and be less than 20fps ( gpu usage can also be lower than 50% ) which is a sign that the cpu cant deal with the core to core data transfers and although the standard sandybridge and the ivy bridge are great cpu's i dont think they will have enough grunt when under threaded loads with what i want to do in flight sim. With the 3930K i plan on getting im only planning on running 6 threads for fsx and not the 12 that can be gained with hyperthreading.

 

I do see that the SB-E's tend to get slammed a lot by people who never use them, and rated very very highly by those who do use them, and the current ivybridge and sandybridge seems to be a mixed bag of moaning and praise.

 

p.s Ivybridge-E has been delayed until 2013 ( second quarter maybe ).

Hmmmm....Nope! :Hmmmph: However, it is your money, so "spend away"! :db:

that it is, the only downside to the cpu i want is the cost, but on the other hand as fsx never really made it out of beta imo even with a couple of service packs and i hope that in time my choice of cpu will be better suited with Prepar3d and the ongoing development and support it has. As they say.. only time will tell :)

 

I would rather waste my money on a decent pc build at this time than second rate fsx addons and sim hardware that i seem to of done based on reviews saying they are great.

With my current i7-960 i have noticed that i can run at 30% cpu load and be less than 20fps ( gpu usage can also be lower than 50% )

 

That's simply because FSX is limited by ONE core. The other 3 cores can't be maxed out so adding more won't help much if at all

i should of posted that when its running at 30% load that none of the cores are running at 100%

Frame rate limiter in place maybe?

while i do cap at 30fps i dont use any external frame limiter, anyway we seem to be taking this thread a little off topic :)

 

I think with what ever we buy if it works for us and works well then its a good thing no matter how much money we decided to invest. Im going for high performance under heavy load conditions instead of ok performance under heavy load conditions.

Do you think it's possible P3D will be reworked to make better use of multiple cores, or is that really not possible or even likely
