that green font is unreadable... show me benchmarks relevant to what we do on xtremesystems, we already know amd does well in server tasks with muti-socket setups.

[[XC] riptide]

Great! Yawn.....

[safan80]

let me go out and grab a Barcelona, NOT.

[JumpingJack]

This isn't terribly shocking.... Intel will choke on heavy BW apps like this compared to Barcelona.

[cegras]

Is this a lukewarm response from intel fanboys that I'm feeling?

And personally, meh.

[grimREEFER]

im assuming this is a fsb bench lol

[Spawne32]

amd guys are desperate now

[ak_47_boy]

Nehalem will have double the bandwidth of Barcelona anyway.

[savantu]

No matter how powerful a core is , if the memory subsystem can't feed it with enough data , it will lose BW dependent tests.

Barcelona has a 40% frequency deficit, but enjoys a 300% memory BW advantage ( + lower latency ) .The later more than compensates.

Intel will ship Nehalem in Q3 , it is in a hurry simply because there are a few apps where K10 offers a decent platform vs. Xeon.Nehalem will change that across the board.

no and you are bagging the argument

[xlink]

don't care. I want performance in things I do and a synthetic that's not even widely used by benchers is not something I do.

[zanzabar]

this is a 2cpu with 4cores each so there is no comparison from the amd using ecc and the intel with FB-dmm, this dosnt reflect a desktop chips at all

just for the sake of curiosity, what makes you think SPECweb is to judge desktop performance?

Isn't that akin to saying a 32P Intel server is worthless, since it gets beat by a 1P desktop with a good graphics card at video games?

[JumpingJack]

Flame thread... flame thread !

Let's not take away the key strength Barcelona brings to the table gentlemen. Argue the data, not with who is fan of what...

Barcelona has much better aggregate BW available to it... the Spec scores for this bench are very high throughput demanding loads, Barcelona should shine here if the load is limited by the pipe giving or taking data from the cores. If the bench were CPU core limited, the story would be different.

Spec scores are up for barcelona on both the FP, Int and the rates, the data says the same thing... in core limited workloads Harpertown/Clovertown is strong, in BW limited workloads Barcelona is strong.

Intel leads signficantly in SpecInt, AMD is leading (adjust for clock speed) in SpecFP_rate. The data is availble here:

My buddy does procurement for an investment bank's server farm. I play Crysis. He's psyched about Barcelona. I like Penryn. What's to argue about?

[saaya]

wow, so after months and months of looking for a bench where barcelona outperforms c2q cpus, they finally found one

[BullGod]

Well, if there was no such thing as Nehalem this would be something. Still the Opteron was a great processor so there's no wonder these are good at certain tasks. Too bad they don't at above 3Ghz properly...

[Mungri]

Sorry, I'm snipping this post as I didnt realise this was a server chip when I posted it.

Yea, i'm a dunce at server stuff (puts on dunce hat and goes to sit in the corner)

[zanzabar]

opteron's have their place and with 4cpu setups they work the best

[Mungri]

Snipped too, see above post for why

AMD chips rape C2Ds in openssl key generation too but there are probably only like 0.0001% users that need it

[ubuntu83]

I dont think many people use 4 CPU setups at home, but I agree that Opterons (and Athlon X2's), back in the days of S939 were awesome.


Again, you have to relate it to what people use their PC's for. 4 CPU PC's are only going to be used as servers, they dont make a cost effective PC for use in the home.


I have been reading through benchmarks after benchmarks after benchmarks at just about every major PC hardware site, and the message was very clear in all of them - the E8400 at stock speed currently outperforms every single AMD CPU availiable. This performance leap is seen even clearer in multi GPU setups, where every current AMD proccessor is a severe bottleneck in both SLI and Crossfire setups and they fall too far behind even Intels mid range dual core processors.


If AMD release a better CPU, I would buy it, just not untill my current setup is outdated, but when I do a whole system upgrade again in another few years.


I made do with an Athlon X2 4400+ S939 with 2 Gb DDR1 untill february, for 3 years after I initially built a S939 PC. But the E8400 was the temptress that made me upgrade, I didnt have any reason to upgrade to any new CPU's from AMD, and it doesnt look there will be a reason to choose AMD now for a long time to come.


And thats not fanboyism, its a case of one mid range CPU by intel completely outperforming everything that AMD has to offer right now.

So what are you trying to prove here Newton. Xeon and Barcelona are server chips not Desktop.

[Shintai]

That many?

There is also the memory BW benchmark. So thats up to 3 cases now!

But again, if you run this kind of things you would use a single Sparc T1/2 chip thats designed for this and get a score of about 37000. So nobody would buy Barcelona or Xeons for this if performance mattered.

[gOJDO]

LOL, what a pathetic and fanboyish thread.

An AMD configuration marginally outperforms Intel configuration in 1 benchmark and somebody made a thread about it, claiming superiority of the AMD configration.

If anyone didn't noticed yet, the Intel system is using Harpertowns with FSB 1333MHz and FB-DIMM DDR2-667. There are Harpertowns with FSB 1600MHz(X5472, X5482 and QX9775) and FB-DIMM DDR2-800 which are outperforming Barcelona in SPECweb2005.

This thread is misleading and pointless and IMO should be removed.
