News AMD's 12-core Magny-Cours leaked on eBay

Howdy simulations

Given that we spent £2k at work for workstations with two Xeon E5520s, i.e. 8 logical processors, and 4GB RAM, spending 6x more on 48 procs with 64GB RAM makes it worthwhile

 

talk about putting all your eggs in one basket

 

Does Intel have a 12 core CPU I haven't heard about?

 

is this even legal? if it is legit?

 

im curious as to whether 12 phenom cores will outperform 6 gulftown cores with HT

 

That's an interesting theory.

 

Why? They are completely different types of CPU. Gulftown is mainstream sk1366, these 12 core AMD's are server designed for 2 and 4 socket G34 systems, the 2 will never be benchmarked against each other.

The closest thing AMD will have to a i7 competitor will be the 6 core Thubans.

 

gulftown doesnt just refer to mainstream i7 cpus - its the codename for the Xeons too:

perhaps Beckton would be a better comparison.

 

Ahh, I was getting Gulftown and Gainestown mixed up (again). Damn if theres 1 thing Intel could learn from AMD it's how to do sockets properly, having 1156 and 1366 both using mainstream i7 branded CPU's then changing from a dedicated server socket to 1366 aswell... it's almost like they were TRYING to confuse us. :S

 

The PC... I don't drive. Too much drinking in my life.

But am I the only one that think that 64GB of RAM are not enough for 48 physical cores? I mean that's just not overkill enough for me.

 

no, that's what i thought at first, thinking 128GB would be more suitable for such a machine.

think about it, one of my university's remote access machine i regularly has 24GB for a Xeon i7 equivalent. and most of the time it's got more than 16GB used up with 2 or 3 cores being busy. so for a 48 core server, 128GB is still a bit low.

heck, even my own rig has 2GB for each core, and looking to upgrade to 16GB. that's just a gaming machine.

 

but technically you only have 1gb per logical core?

 

well there was an 80 core that they used for testing, like, 3 years ago IIRC?

Really? Why? I regularly multitask between high-end games and 'low end apps' like open-office or firefox, and I don't think I've ever seen memory usage over 3GB (yes, I'm 64bit) or any significant slowdown on my quad core system. Are you multi-tasking between instances of Crysis?!?

As to the 48 core situation, in theory I suppose you'd probably need over 64GB if you were running that many threads, but without real-world tests what theory worth?

 

Do want.

 

until i actaly see one of these servers in action and have all the specs im after then its a no go for me due to the no returns!
i think it would be a great idea to phone the bloke go and see him and ask him to benchmark it in front of you so you know your getting your moneys worth!

please use uk ebay

 

you and i both know that HT doesn't increase performance by that much, from cinebench's ~3.5x to ~4x over single thread performance on i7. so compared to AMD's true 12 core CPU, all Intel's parts are behind, most cores from Intel is just 6 cores.

try regularly multi-task between virtual machines. 8GB won't be enough and 64GB won't be enough for a many-user server.

Crysis is not the end of all, as CustomPC's latest mag shows, there's way more demanding stuff out there, such as graphical work station.

 

i know, i was only being pedantic
But still, i would like to see if intels 6/8 core nehalems are faster than a 12 core opteron.

im just going off the performance difference between the 4-core opteron and the quad core Xeons. according to CPC it was about 30-40%, so will the 8-core beckton be competitive with a 12-core mangy-cours?

 

Core Blimey (sorry it took me a day to come up with that)
