Core i7 940 Review Shows SMT and Tri-Channel Memory Let-down

[iRRegular]

Nice! Post some results as soon as you can, please.

Oh, I forgot to add:
Nehalem is here!
Intel Smackover MB,3200EE unlocked cpu,3x1 gig DDR3-16000 and a TRUE..
Let me see..HMMM.. What multi to use???
What is 4000 divided by 133?
Only kidding.. I'll be a happy camper if everything fires up ok.
This is new to me also..

omg.. to bad you cant show any pictures.

so if we watch your folding scores closely, we may have an idea about how fast nehalem is

Only to find out your board is bad and needs replacement after you drooled too much on it and started it up

The No.1 rule...drool and electronics dont mix

Riiigghhttt, you forgot to add. You just wanted to tease from the top of your overclocking mountain.

you're getting me nervous!!!! me want results or at least a clue to confirm if the current benchmarks are real /faint

well well ?? it's been a hour+

Pictures, with anty japanese :banana::banana::banana::banana: jaggy filter ... Anything !

Like I sad response time issue that is all, nothing to do with the FPS.

Metroid.

response time is a function of the framerate in quake3/cod1-2-4, look it up if you need to.

[Revv23]

congrats MM have fun!

Make sure to link us to the thread if you make one about it!!

[Metroid]

Now a question to you. Do you think what they did regarding to level the frame rates up to get a standard response time was okay?

Personally for me if the game runs at 60 FPS which means real time I would expect the game to have a standard response time like any other game even in consoles, emulators and so on.

can we drag this discussion about a decade old game engine into another topic, i really dont think anything of that is news.

Yes sure, I do not want to take Movieman's glory away.

That was the level loading times, saaya.

The 2 trichannel slides is time to load the game in seconds.

ahhh i see, thanks

its still slower than the 9770 in cod4 though?
and smt makes it even worse? weird...

I think it's because it's a imature platform as DrWho? pointed out. A/w, CoD4 is not the most multithreaded game around. Mass Effect, Assasins Creed and SupCom would be good tests.

And those SMT results reminds me of P4 when HT actually slowed down a lot of apps.

I have been mulling in my head what situations could benefit and what could be a liability with SMT for quite awhile.... my real problem understanding is how does the thread scheduler prioritize threads.

Scenario: A two threaded application runs, question: what core is scheduled?

The presentation to the OS of 8 logical cores, 4 physical cores raises a conundrum ... a dual threaded app will best be served by running on two physical cores, does a thread scheduler realize or is it aware of the optimal way to schedule the threads?

Makes sense, if it uses a physical core and a logical core, then the performance is way worse then 2 physical cores? Could that explain some of the "subpar performances" we've seen? Software or windows will have to re-order the physical and logical cores then, IE use all physical cores first, then logical whenever needed.

[TurboDiv]

If this thing is not killing in games I can see it as Q9550 now and than I'm waiting for the "tick" version of Nahalem, or not...

Well, I have only really seen in the data sub-par performance in gaming... in multithreaded code, in general, it is performing well overall.

Nehalem will be a mixed bag ... and it will be interesting to see if what we are seeing is simple immaturity in the BIOS and platform implementations, and other more controlled studies than just leaked asian benchmarks.

...and to find out whether Turbo mode has been active all along or not.If it was,then all the clock for clock comparison tests(even the 4 threads ones) we have seen so far will be meaningless.If it wasn't active,then Nehalem will be a good tick after all.Games are not everything...There are more and more apps being optimized for many-cores designs so the design will be ready to make use of this fact.The only problem that remains is the level of threading software designers will be able to produce.4+ threads will work great in some cases while in others it won't work that well.Boils down to what is easy to thread and what not.

[demonkevy666]

need a few more games testes SMT is used for paralleling threads.

Another good point ... but, if anything, Nehalem is going to highlight very well apps that are well threaded and those that are not.

I am, as many other are, questioning the wisdom for designing in such a lean l2 cache -- I mean 256 K is quite anaemic ...

Frankly, it won't be until we see the launched platforms, people here at XS get their hands on them, and appropriate mix of benches done with the smattering of BIOS configurations to really figure this out.

Just wondering, has anyone compared nehalem to q6600? A lot of people still have them and if the QX9770 is that much better in these tests, I'll stick with cheap stuff for a while.
