Intel Unveils 10-Core Xeon Processors
MojoKid writes "Intel announced its new E-series of Xeon processors today, claiming that they will deliver nearly unparalleled advances in CPU performance and power efficiency. It has been just over a year since Santa Clara released its Nehalem-based octal-core Beckton processors. Whereas Beckton was focused entirely on performance and architectural efficiency, these new Xeons are more balanced. The new chips boost the core count to ten (up to 20 threads with HT enabled) and will be offered at a wide range of power envelopes. The new E7 series incorporates the benefits of the Sandy Bridge architecture, its support for new security processing instructions, and its improved power management technology. Intel has also baked in support for low-voltage DIMMs, which allows vendors to opt for 1.35v products."
claiming that they will deliver nearly unparalleled advances in CPU performance
What's the point of having 10 cores then ?
130W TDB at 2.4 GHz, on the high end. Sadly, that information wasn't in the posted article. http://news.softpedia.com/news/More-Details-About-Intel-s-Upcoming-Xeon-E7-8800-CPU-Line-Emerge-183270.shtml
Surely they will be *more* paralleled than any processor before them :-D
That's almost impressive.
Finally had enough. Come see us over at https://soylentnews.org/
Absolutely no doubout E-series of Xeon processors today will be hot one http://maxwd.com/

I've got a SB desktop computer and it just screams. they made some sizable per-clock performance improvements. Also AES-NI is no joke. I am pretty amazed by the speed. Tryecrypt supports it and the benchmark difference is huge. With a 100MB buffer a pure software AES implementation benches at 649MB/sec on my system (553MB/sec for Twofish, 254MB/sec for Serpent). Same test with AES-NI on, 2.7GB/sec. That is 4.2x the speed.
Could be really useful for web servers, particularly if you are looking at going all SSL all the time.

Gotta love the milking of the consumer, giving them each tiny iteration, sucking them dry for every penny. Too bad all the real technologies are suppressed; that you pay for with your tax dollars and can not have.
why don't you felonious billionerror fauxking murderers & thieves just vote yourselves in again, then turn off the lights, & go home (zion, or where ever). don't come back. we don't really need self-worshiping murderous crooks to tell us we can't afford to care for our children, sick & elderly, but can afford to facilitate the murder of others' children, elderly etc... for our 'defense'. the time to leave, has past. go. now.
with the genuine native american elders rising bird of prey leadership campaign, we'll get by. even better. goodbye.
another possibility would be to disarm, then shut yourselves down voluntarily. babys rule now.
This is what the craze of liquid cooling systems was all about. Time to buy a large radiator.
Even I've got a machine with four of those in it and I waited about a year for the price to go down.

The new E7 series incorporates the benefits of Sandy Bridge
is a bit misleading, i think.
As far as i understood it uses the older Westmere EX architecture. So while it may have added instructions also available in the Sandy Bridge architecture, clock for clock it will likely be slower in most cases and probably won't reach the the clock speeds of Sandy Bridge based chips.
Hopefully Bulldozer will fix it but right now, they don't do so well. Have a look at this HardOCP article on the new SB processors (http://www.hardocp.com/article/2011/01/03/intel_sandy_bridge_2600k_2500k_processors_review/3). They tossed in a high end 6 core AMD CPU too. It just gets killed. In many tests, it is below the older 4 core i7 CPUs, in pretty much all of them it is below the 4 core SBs and I don't see a one that it beats the 6 core i7 (the 980X).
AMD offers more cores, but their cores don't do as much. Don't buy in to core hype any more than MHz hype or anything else. More is not automatically better. Have to run benchmarks on it and see how it actually does.
Like I said, hopefully Bulldozer will change that. Hopefully it'll be competitive with Intel per core, per clock and so on. However right now Intel processors just kill.
"...they will deliver nearly unparalleled advances in CPU performance..."
Good to hear. Hopefully the next iteration will be fully unparalled. Much easier to program for a single core.
Am I the only person who initially read that as "It has been just over a year since Santa Claus released its Nehalem-based..."?
just metaphorically as yet. they are still being built. the greatest story ever to be untold? tag team interviews from real people, guaranteed to generate facial expression images that are hard to focus on, yet impossible to forget?
so far, all of the highly eligible contestants have the same reply; 'we're not going in the cage, plus we still want to kill you, & almost everybody else'. so we'll see?
1 core, 2 core, 4 core, 8 core, 16 core, 64 core, 128 core, 256 core, 512 core, 1024 core, 2048 core, 4096 core, 8192 core......

Dear Slashdot, I can't click through links or bring up the right click menu in comments any more. Also, the site has been getting slower and uglier with every 'upgrade' for years now. You need to either find a competent fucking web designer and do it right or revert back a couple versions and then STOP FUCKING AROUND WITH IT. This was never the best designed site in the world but at least it sort of worked before, I barely bother coming on here any more now because it's so bad.
And if you're gonna run around adding a bunch of useless crap to everything could you at least add an option for a WYSIWYG mode? And because you're a bunch of slack-jawed, drooling, smelly, flabby, basement-dwelling morons I want to spell it out clearly and say that it needs to be A MODE and NOT the ONLY MODE because I'm sure you'll fuck it up too and we'll have to go right back to raw html, but atleast then you're gigantic steaming heap of broken javascript would actually have a useful goal in mind and maybe the effort of making it work right would distract you idiots from fucking up the site and making a bunch of retarded dupes/slashvertisements...

Though these do not seem to have all the Sandy Bridge technologies. In particular, AVX isn't listed. Thus is does not seem to have new SB instructions. Maybe they are talking about the improvements to the existing AES-NI instructions (SB is faster with those than older i7s) however it does not appear to have new extensions.
I don't know that AVX is of much use to servers, but it does mean this isn't SB architecture. Which means it is not as efficient per clock (SB made some good gains in that area, not that the original i7s aren't pretty efficient already). Also mean it probably doesn't have their new turbo boost tech. That isn't a huge deal, but is nice. It gives a wider range of boot options depending on how heavily cores are loaded.
On the older processors you find 1/1/1/2 is a common turbo boost spec. That means it can increase 100Mhz at most with 4, 3, or 2 cores loaded and 200MHz at most with 1 core loaded. For the SB processors it is 1/2/3/4. It's a bigger deal for mobile, since they are clocked slower and have bigger turbo boost levels, but still nice for desktops and servers. Means if something hits a single core hard, you can get a non-trivial clock boost.
Does make it less of an interesting announcement. More cores is cool and all, but SB is neat because of the new architecture. Apparently that is still to come for servers.
very nice post.good information.

...a Beowulf cluster of these!
Any CPU with where the number of cores is not a power of 2 makes me uncomfortable. Six cores, ten cores - it just feels wrong.
Octal is a numerical system: adj: "relating to or using a system of numerical notation that has 8 rather than 10 as a base."
and
noun:"the octal system; octal notation."
Perhaps they meant:
octo- (also oct- before a vowel)
combining form
eight; having eight
I think working in octal will give a huge performance boost as compared to working in BINARY.
One would think that would have been touted as a major feature as going from on/off to on/2/3/4/5/6/7/off states is a nice break-through.
Each octal-bit now can now store 256 states vs on/off previously. Instantly increases memory density, bandwidth on the bus etc.
Nah, that was probably 100 years ago courtesy of F. W. Woolworth. Before that everyone liked quality too much. Unhardened steel hats!

Never hit your grandmother with a shovel, for it leaves a bad impression on her mind...
just what we need a $2500-$3000 1 cpu system with a low-mid range video card and like 2GB ram at the base price.
Could be really useful for web servers, particularly if you are looking at going all SSL all the time.
Sure, except you also have to worry about algorithms like RSA, DH, SHA1, SHA256, SHA384, SHA512, and providing a good source of random bits as well (hardware RNG).
That's one thing I like about Sun/Oracle's T-series chips: they have all the above algorithms. A ~4 year old T2 chip can do RC4 at 81 Gb/s, AES-128 at 44 Gb/s, and AES-256 at 31 Gb/s: that's enough to saturate 10 GigE connections (in both directions at times). SHA-256 at 41 Gb/s and RSA-2048 at 6400 op/s make for very fast web secure servers.

If companies web companies want to offer HTTPS, they just need to throw up a bunch of these as SSL proxies to feed back into your normal (Linux) app servers. Given that they run Unix (Solaris), you can probably leverage a configuration management system (e.g. Puppet) in a lot easier fashion than you could an appliance-based load balancer as well.
From one of the articles linked to in this thread: "Watts Consumed (lower is better)"
To me, that's not an unbiased opinion. I work for a power company, guys, and I don't like to see this slanderous talk on a website as prestigious as this one. Plus, it's still cold outside. I have the data to prove that my computer room is, on average, 10% warmer than the entire rest of my house - and it's on the bottom floor. I just want you all to remember that you can run your computer all day and it won't drive your gas bill up _one cent_
Seriously,
that goes to eleven?
Huh? Why are the core operating on octal? Does this new version run in decimal?
antipaucity
imagine a Beowulf cluster of those..
Will i have to send a small drilling robot to nuke the middle core if i need to reboot?
My cores go to 11. None. More. Parallel.
I can't wait to eat that monkey...
First glance at benchmarks indicates that this is still a bit slower than Power7, and has a similar or more expensive price. Considering we're a few months away from the Power7+ kicker, I don't expect this to have much adoption outside Windows Server users.
Not all tasks are of an equal load at all times. You can have situations where there is a strong load on less cores, and then later ones with a load on all cores. That's the reason for such a thing to exist.
Not only that but turbo boost doesn't just work with how many cores are loaded, it has to do with electrical load and thermal load as well, hence why it can be active even if all cores are loaded. So it allows for a chip to meet a given TDP, but then if cooling is good it can go faster, and scale back if not.
It's a useful technology that'll hopefully keep getting better. The more flexible the scaling, the more energy efficient CPUs can be when lightly loaded and the more powerful they can be when heavily loaded.
What happened to the 80 core universe that Intel promised years ago? That would be unparalleled for sure!
yes, it's very fast.... you can get information about this on http://www.sawanswers.com/search?q=process
