Gulftown "i9" in Q1 2010 (Digitimes)

[Greg83]

But more cores are better then higher factory overclocks
I just wish core i7 started at 8 cores

[Sn0wm@n]

more cores = to less core at higher clocks.. because in the end they all output about the same raw processing power right??? and since their biggest costumer are big server and not desktop they focus on that.. but still dedicate founds for R&D to improve on thermal envelope while increasing overall perf each year.. but the biggest problem in the desktop is the fact that we cant really use more than 4 cores.. so what we need is an app or some sort of cod integrated into windows to allow multi threading easily

[JPQY]

That is what Chess exaclty has...the integrated cod is now optimal using all the cores at 100%.
And if you look into my list you can see that for example a E8600 @4.9Ghz is already much slower then a core i7 920 @2.67Ghz Stock speed!!

89) TogaII142JD-2cpu 20/43 02:26 36.452.932 3.971.241 +0.29 E8600 @4.9Ghz DDR3: 8-8-8-21

So lower clocks but more cores gives me in this example 1.356.582 positions more in one second!!
And you can see if you overclock these multi cores cpu's to higher levels what speed gaines you get!

It's very clear,the more cores is much better,only game sofware is behind,except some off them and like Chess software!
And this year testing Cluster!

nope. we need raw performance. there are a lot of things that can't be executed in parallel, so even more cores are going to be obsolete!

since when are the biggest customers server and not desktop?
far from it afaik... similar to professional graphics server cpus have a very high margin, but its a limited market and intel makes more money selling entry level and mainstream desktop cpus than server cpus for sure...

but intel and amd are cheap and dont want to create two seperate cpu lines for server and desktop, so now they are going to simply seperate the two lines by adjusting the amount of cores per cpu.

if you know so much about coding you KNOW that most code can only be parallelized so much and some cant be parallelized at all...

This is making me think I'll save cash and go i7 instead of i9 since I can't use i9 and its an absolute waste for me, unless the cost is the same AND the OC results are the same. Otherwise, screw it. 6 cores is a waste unless you're doing 3dmark, folding, or chess, lol.

i dont think this really helps in 3dmark... sure, itll boost the cpu score, but im not sure if more than 8 virtual cores actually result in a propper boost... dave? can you prove me wrong? ^^

[JohnZS]

I think that this is what I am going to upgrade to from my QX9650.. a nice 32nm Hexcore
Intel never fail to surprise me with their innovation and superior products to the opposition.
1) They make the best CPU's
2) They make the best chipsets
3) They make the best SSD's (consumer level)
4) Are they going to go the same way with their GPU's?

Now this is somewhat apples/oranges because of the different archs,

But, *ballpark* numbers, 2c @ 5ghz should match with 4c @ 2.5ghz. Youre saying 8c @ 2.5ghz is winning? Well, duh. It's twice as much. You should be expecting 4million calcs/sec more but you're only getting 1.4m. And you say it's using all cores/threads at 100%.

You'd be better off clustering two of those 2c systems, assuming you can cluster at 100% efficiency (probably not realistic).

It looks to me as though it proves the opposite of your theory. What of power usage? That can tip the scales (even tip them either way when you start considering clustering).

That said, I'd still buy a quad over a dual, personal preference.

Does chess excite anyone else as much as this fellow? To each their own!

no, your right in all but Vantage and maybe PCMark06..
in 3DMARK06 I got killed and it is the failure of the program to take advantage of what I have.

Probably because their R&D budget is higher than all of their competitors combined. (although that is not the sole reason it does play a major role)

see dave! :P :P :P

i made a similar comment but it was removed cause dave thought it was too rude mentioning that nobody really plays chess, of those that do, i think online tournaments are much more interesting than playing vs your little grey box

can you do a quick run and try so we have some direct scores to compare? or is there no gain whatsoever?
you can disable 2 cores on one cpu, right? that would get you 6 cores with ht... with numa and all, but that shouldnt matter too much for the cpu test.

[Hornet331]

well thats what doesnt make sense though imo...
they hit a power ceiling? gulftown will have 6 cores in a 135W tdp, right?
thats 22.5W per core... now remove uncore and L3 cache and imc, and your left with an actual tdp per core of less than 20W... that can hardly be the power limit...

L5335

thought it only clock to 2ghz, they have a TDp of only 50W so that means 12,5W per core TDP (which means they acutally consume less).


20W per core on 32nm and 3rd generation HKMG should be enough to deliver a cpu that clocks around 3ghz.

[poke349]

I'm looking forward to Gulftown.
My Gainestown board is supposed to take them with no issues..12 cores/24 threads....MMMMMMMMMM

You're gonna need it Dave...

The guy in Japan just announced new results on his well-tuned dual W5580 rig... And they beat down all your speed records...

And he took them up to 32G... That's 34,359,738,368 digits of Pi - done in 8 and half hours using 70GB of ram and 80GB of disk.

[cegras]

I think a major problem with high clockspeeds has to do with signal integrity. At such high speeds, it becomes very hard to distinguish noise from signal, I should think.

[TheCarLessDriven]

When are we going to see a fundamental change in how they produce these chips, geared more towards clock speeds?? You would think by now we would be at 4ghz stock chips shipping. Why are we still in the 2.5ghz low 3.0 ghz range stock?? These 6-cores should be shipping with 5ghz stock IMO. back in the Pentium 4 days they were all about speeds going up. Now its all about cores that cant even be utilized to their full extent by most people buying them.

[The Coolest]

The frequency races died with the P4, Intel pretty much ran the P4 design into the ground a few times during it's life-span. But they discovered that it is easier to make more cores which run slower at much lower power consumption than making those existing cores run much faster in the given power envelope.

IIRC, IBM's POWER6 series of CPU's were running at stock speeds of nearly 5.00GHz.

Perhaps there are certain barriers in the x86 ISA that make scaling clock speeds with sustainable levels of power consumption difficult?

[duploxxx]

I don't know. But I hear AMD will have its flag at half mass that day

Perkam

on crown x86 performance...yes
price is a whole different game... beckton will be expensive like hell.. and is actually aiming to get some unix marketshare.

perhaps you should talk to some Intel PR, they reach out to each company that uses unix boches to provide additional free services and hardware for conversion to x86.

That isn't anything to be happy about considering its a workstation chip which usually have TDPs 20-30W less than desktop chips.

All Bloomfield based Xeon's have 130w TDP just like the desktop i7's.

This only changes with Gainestown whose X55xx has a tdp of 95w

Xeon Gulftown lock multiplier

[Hornet331]

hmm 19 multi, not that bad would be nice to replace my 3.8ghz 24/7 bloomfield against a 3.8ghz 24/7 gulftown.

[Helloworld_98]

the retail chip will probably have a higher multi than this, Intel aren't stupid enough to put a CPU at 2.4GHz in the high end consumer market.
