E7-2870

They should make quad socket boards for this. Still nice with 2x 10 Cores tho.

they probably will with lga-2011 to compete with the opteron quad socket bulldozers.

wonder how she fold :)
Click to expand...


if you want to pay the price tag premium, it will fold. does it matter? obviously no since its not going to overclock any better then its consumer based version and odd's are we wont see an overclockable multi-socket board for lga-1155.
 
lol... sorry... let me rephrase... I will tell you its ppd if its stable enough to fold :)
 
^^ You have one?!?!?!?:eek: What socket?
Probably mainly for 4 socket servers. If they have <$1500 10 core ships come out for socket 2011 though I would probably get one. For [H]ardcore folders though two of those at 4.3Ghz with quad channel ram would probably push close to 400-500Kppd.

its 2p...
I honestly don't know the socket... it looks big like 2011 but doesn't have the double latch mechanism
at the same time its not 1155.... its 2p...

perks of the Job... I get to play with stuff before it comes out...
 
Does it have turbo? 2.4ghz is still pretty fast for 10 cores. It could easily get 60kppd with one CPU, do you have 2? How many channels of ram? It looks like those are several thousand, pooie. We still want PPD.

ahh shit i missed the 10 core part, lol.


doing some reading up on them.

they are "based on the 32nm Westmere architecture and their operating frequencies range from 1.73GHz up to 2.4GHz".

there are 2 variations of them the E7-2xxx are 2p and the E7 4xxx are the 4P versions.

they have 2 dual channel DDR3 1066 IMC's which equates to quad channel DDR3 (same design as AMD's G34 socket)

my guess is these are the stepping stone processors before the xeon sandy bridge processors come out later this year.

links for the info i found.

Yup first site is where I get most of my raw data specs... when I read 30mb cache in the bios I had to go look it up lol...

loaded up rhel on the system... gonna try to get this image on it next...

E7-4870 :D:D:D:D:D:D:D:D:D
4 CPU's x 20 thread's each x 2.4GHz = 192GHz of folding power! :D:D:D

Est ppd for a 4 CPU beast would be.....420k????

If it scales the same as a i7, I'm guessing a TFP of less then 5 min. And at 5 minutes your at 420k.

ppd/kw would be awesome!!! :cool::cool:

Price per point would kill a normal man! :eek::eek:

It's nice to dream!!!!
 
anyone know how to get into the beta program for f@h?

I really want to run bigadv linux native... the iso I posted doesn't see my hard drives behind the raid controller...

not so fast buddy.. its not 4 x 20 threads x 2.4Ghz= 192Ghz

a physical + logical core does not equal 4.8Ghz. its more like 3.5Ghz. a logical core thread is not equal to a physical core thread in performance. its roughly about 40-60% depending on the application with a 10-20% loss in performance on the physical core thread depending on the application. (its why you see better numbers with SMP 7 vs SMP 8 or smp 11 vs smp 12 since the 4th/6th physical core has access to all its resources)

consider it like this..
the E7-2870 has 10 x 256kb L2 cache. so thats 2 threads per core sharing 256kb @ 128kb per thread. then consider the fact that the processor has a total of 30mb of L3 cache, so 30mb / 20 is 1.5mb of L3 cache per thread if you were to completely max out the processor plus L3 cache usage. mind you the 30mb is shared between all threads so 1 thread could use more then other but thats not the point of this.

so in the end they decided to choke the processor to death on L2 cache while giving it an asinine amount of L3 cache that barely anything uses and nor does F@H. so the end result is while this processor sounds awesomely cool, its not meant to be used to run F@H. doesn't mean you cant but i wouldn't expect any crazy numbers out of it.

and yes i know i used the 2870 as an example but the 4870 is the exact same processor only with 4p support.

Blah, Blah, Blah

If you even owned a Intel i7 I would consider your argument, but you don't, so you have NO idea where these number came from!!!!!! :eek:

And until you ACTUALLY OWN an i7, I'm not explaining it to you!!! :D:D

lol... you have one so you should know threads vs cores are not equal... turn ht off and bench... you get a 20% performance boost by having it on... not 50%...

there is not an i7 in my sig... but I have built with them... I just got tired of them... and use amd hexacore for my main rig.

please no useless flaming...

Anyone know how to get into the beta program so I can get this puppy on linux bigadv :)

i dont need to own an i7 to understand how hyperthreading works. its not like its some new magical thing, i mean shit its been around since the P4. Intel didnt just change how hyperthreading works. its the same friggin process as the P4 hyperthreading.

and to end this pathetic arguement, there isn't enough money in the world to ever make me want to own an i7, and even if AMD died as a company, i'd still never own an Intel processor. but that doesn't mean i don't know how the i7 works.

as far as the beta program goes patriot, like lord of doors said Tobit would be the best one to ask. or talk to one of the mod's on the folding forum.
 
wasnt there a thread on here about them looking for more beta testers just recently?
 
might have been... I have not been regular here that long...

nitrobass pointed me to the right spot through pm... thanks...

hopefully I can get some ppd numbers for the E7 2870 up before the end of the day...
 
just wondering.....with all the "toys" you get early access to, are you a witch?

lol... no... otherwise my house would be full of early toys... instead I only get to play during my lunch break or after hours depending on my work load... and I am currently working part time... so just Tuesday and Thursday...

got handed this one this morning... with no apparent reason for my team having it...


Then again... when certain toys from other labs hit the scrap pile.. I double up "my" machines or send them to "testers" in various states... can't sell them though...

I'd be happy to help you in *testing* those things out if you get any more spares. I'm certain I could put together an appropriate platform to *evaluate* those chips with.

for normal i7s thats easy to do... for chips like this... unusual sockets... that a 2 grand board...

I am leaning towards thinking this is a socket lga 1567 chip...

:( I don't need to stay late tonight... I will have to get ppd numbers on thursday... look for the update...

you didn't ask that question... you asked if I was a witch... I said no...

I have an internship with HP I get to play with hardware 6mo to a year before it hits production...

because of nda's I cannot detail these systems ... the cpu specs are already public...
 
ahh sorry, meh interesting job :D

thought i was more clear, re reading it i guess i wasnt
 
gah.... 2685 .... 30min 16s/frame

36986ppd

1 cpu, 10cores/20threads @2.4ghz 8gb of ram.

not bad. but could be a hell of a lot better..

so say 40 threads scales correctly and cuts your tpf from 30:16 to 15:16 your looking at roughly 103k PPD. though i'd say your more likely to see 80-90k PPD with a 2P rig.

until there's an overclockable version i don't think these will be the first choice as a folding rig processor.
 
no it won't ... its rather cost prohibitive...
I am curious what its ppd is on a nicer wu...
 
It won't get much better than 2685.

2684 is the bad one.
Posted via Mobile Device
 
P6900 would probably be the nicer WU. but i dont think you will see much different from it. probably 45-50k PPD at the most. the killer is the clocks are so low..

btw you are running the processor in quad channel DDR3 correct?
 
Just for perspective my Dual Xeon E5530 @2.4ghz 8core/16thread is around 31min TPF on a 2685.
 
That actually seems slow to me for 10 + 10 cores @ 2.4. My numbers with an 8 + 8 @ 2.4 were close to what Nitro reported. 12 + 12 @ 2.4 was in the 20:00/frame range on 2685s. I would expect 10 + 10 @ 2.4 in the 25 minute range, which should equate to around 50K - 55K ppd.
