Intel readies a six core chip

Intel readies a six core chip

I am Dunnington, hear me roar.

A PDF shown off by Sun Microsystems leaked onto the net yesterday detailing Dunnington: Intel's new hex-core CPU built on its 45nm technology. In contrast to Intel's quad core designs, It features a single die with specially designed Penryn cores that has pairs sharing 3MB of cache, instead of the usual six.

These are then all bolted onto a massive 16MB of shared L3 cache and also connected to a 1,066MHz bus interface. The L3 cache is there to compensate for the latency and bandwidth stretched front side bus - six cores competing for access should seriously stress this interlink and its access to main memory and the rest of the system. This will be the last core increase until Nehalem arrives at the very end of this year with up to eight cores.

Further details of Dunnington include a TDP of around 130W and the inclusion of the latest SSE4 instructions, however it will be Xeon socket mPGA604 and will fit into the new Caneland platform but will be pin compatible with the current Tigerton.

No specific desktop use has been outlined, but that's not to say Intel hasn't gone down this path before: the first Pentium 4 Extreme Editions used the Galatin cored Xeon chip which was built on the 130nm design and featured 512KB L2 cache and 2MB L3 cache. While there's no reason for Intel to do this given the fact it's currently leading the performance race, was there really need for the QX9770 either?

In addition, Nehalem's platform was again given a bit more detail - despite the fact that it will effectively contain "the north bridge" as it includes a memory controller, Intel is still using a pair of chipsets in its product design. The I/O Hub will only offer the PCI-Express lanes and talk to up to two CPUs but it won't act as the mediator between them because Nehalem includes multiple QuickPath direct interconnects just like AMD's HyperTransport technology.

Included are also SPEC results that show off Nehalem-EP as one meaty beast, pulling quite a lead over the current 3.2GHz 1,600MHz FSB Harpertown server products.

Six cores - great for servers but useful for desktops? What will AMD compete with? Let us know your thoughts, in the forums.

Ok,

2 Core= Duo Core
4 Core= Quad core
6 Core= SEX CORE?

Btw, this is a fraekin trip!
What are we going to do with it though?

Well..........never mind that question. I can think of great things to do with it.

Wait.. it's not April 1st.

The 1066 bus speed - is that then quad-pumped? Or is that the quad-pumped speed?

"No specific desktop use has been outlined"
so basically its gonna be 2-4 years+ until we start seeing 6core chips in peoples sigs

or 10 moths for 8 core chips.....

Guh, I would've bought a Sex-core PC just for kicks.

Bear in mind intel plan to have 80 core chips in 2012, so we're probably going to see some doubling every year or something like that.

2006 - 2 cores
2007 - 4 cores
2008 - 8 cores?
2009 - 16 cores :D
2010 - 32
2011 - 64
2012 - 128

of course, this is probably completely wrong, but hey there we go :)

is moores law going to start applying to the number of cores in a cpu?
mrb_no1 26th February 2008, 16:27 Quote
i could research this before i ask, but i cant be fecked to do so, but isnt moores law specific to core speed, seeing a max of 4ghz or whatever it was, or did he create moores zeroth law like newton as he realised you can only fit soo many coes on the chip? Purely in response to chris' question.

I can see it now, new AMD 5 core solution with unparalled performance, the note reads: yes, we did it again, a botched batch of proccesors came out of one of our fab's so instead of six, you get 5 but what the hell, maybe we'll get it right one day but for now we'll say that we are covering a niche in the market :P Anyone know what AMD's roadmap has instore for us, will they ever really compete with intel again?

peace

Moores law was just about transistor count, If we assume Moore's law does apply to multicore cpu's and assuming intel would stop increasing the transistor number per core then with a 6 core cpu in 2008 it would mean a 12 core cpu in 2010, a 24 core cpu in 2012... but, Intel wont stop increasing the Transistor number per core, so its rather hard to make predictions based on Moore's Law if it comes to Number of Cores in Future Cpu's.

This is crazy. It's also sort of depressing. No matter how much you spend on an uber high end system, there will always be something better in a year.

Has it taken so long to figure that one out? :P
j/k
No matter what we do the industry will has something better in a few months.. Once You could run DOS 6.22 on a 16MB Ram machine and it would be flying.
Today.. Just to cope with all the bling we need 256 times that amount..

okay so umm I know this is cool and all but what do we need it for? I mean we are just not taking advantage of dual cores, barely have touched the quads and now this???

Who knows how far we're going to end up going with computing power.

Why 6??? Why not just stack 2 quads on eachother and make a 8 core CPU?

Because there silly.:D

they want to milk the market, why release 8 when you can make money selling 6 and then release 8.
chrisb2e9 28th February 2008, 06:26 Quote
exactly, I should of bought a dual core instead of a quad. I dont use the quad and i could overclock a dual farther because there is less heat. no matter how you look at it, if you only use one core out of however many you have, whats the point of even having more than one?
sure in time we will be using more than one core on a regular basis, but in the mean time why spend the extra money.

because they dont have "real" quadcores, their quadcores are two dualcores, so its easy to make a 6 core cpu, 8 cores however would bring more problems with amount of room avalaible, heat output and power consumption (the power regulation on the mainboard woudnt like it).There will be 8 core cpu's from intel, but not in the next few months, wait for nehalem and its new sockets.
