Intel's 32nm Update: The Follow-on to Core i7 and More

Enter the 32nm Lineup
Instead of Havendale in Q4, we’ll get Clarkdale and Arrandale. These are both dual-core, quad-thread processors, and both have on-package graphics. The CPU cores will be built on Intel’s 32nm process and in fact, they will be the first Westmere CPUs shipping into the market.
Now note that the dual-core market is the largest slice of the processor pie. Intel must be incredibly confident in its 32nm process to start shipping it into these demand markets first. Remember that both 65nm and 45nm initially launched on the high end desktop, but 32nm is making its debut in mainstream notebooks and desktops. The 32nm ramp is going to be a good one folks.
| Segment | Manufacturing Process | Socket | Processor | Cores | Threads | Release Date |
| High End Desktop | 32nm | LGA-1366 | Gulftown | 6 | 12 | 1H 2010 |
| Mainstream Desktop | 32nm | LGA-1156 | Clarkdale | 2 | 4 | Q4 2009 |
| Mobile | 32nm | mPGA-989 | Arrandale | 2 | 4 | Q4 2009 |
| 4S Server | 32nm | LGA-1567 | ??? | ? | ? | 2010 |
| 2S Server | 32nm | LGA-1366 | ??? | ? | ? | 2010 |
| 1S Server | 32nm | LGA-1156 | Clarkdale | 2 | 4 | 2010 |
Clarkdale/Arrandale have 32nm CPUs but their on-package GPUs are still built on Intel’s 45nm process; these are the GPUs that were supposed to be used for Havendale! It won’t be until 2010 with Sandy Bridge that we see a 32nm CPU and 32nm GPU on the same package.
A side effect of the Clarkdale/Arrandale architecture is that the memory controller is now located on the GPU and not the CPU, although both are still on package and should still be quite low latency.
Keep following; if you want a quad-core Westmere, your only option will be in the LGA-1366 socket with Gulftown. Core i7 will get replaced with a six-core, twelve-thread processor in early 2010. There won’t be a 32nm quad-core part on the desktop until the end of 2010 with Sandy Bridge.

Might depend on who you buy the motherboard from. My motherboard is a P965 and is not Penryn compatible, though other P965 boards are. There might be both hardware (say, power delivery) and software (BIOS) considerations to future generation processors.haukionkannel - Wednesday, February 11, 2009 - link
Wery little change. Intel ghange their soccets when they do new architechture prosessor. Only reason would be that AMD would be so cpmpetative that there would be a real prize war... By making new soccet they can make more money!Nfarce - Wednesday, February 11, 2009 - link
"Now that isn’t to say that the six-core 32nm Gulftown will work in existing X58 motherboards; while that would be nice, Intel does have a habit of forcing motherboard upgrades, we’ll have to wait and see." Unfortunately, my trusty nearly three year old E6600/ASUS P5W croaked and I need a new build *now* (my PS3 is no real sub for PC gaming :p ). I was going to just go cheap and build an E8500/P45 rig, but after reading this, I'm debating whether I should just go ahead and throw down the extra several hundred on an i7 build for future upgrade insurance. I'm leaning more towards the latter.CSMR - Wednesday, February 11, 2009 - link
Great article; nice work putting it together so fast!weevil - Wednesday, February 11, 2009 - link
My question is this. I've got a QX9650 at 3.2ghz on an x38 asus P5E3 Deluxe. Is it worth upgrading anytime this year to the i7 or am I fast enough to hold out until the Quad Core Gulftown rolls around in early 2010?Decisions decisions...

Gulftown is 6 cores. :)weevil - Wednesday, February 11, 2009 - link
Yikes!Yummy ; )

I guess I'll just keep my Thinkpad T61p (Merom T7300) for another 10 months. Thanks AnandTech.ssj4Gogeta - Wednesday, February 11, 2009 - link
I think this is a very good move.Want the highest end? Go for i7 now and upgrade to Gulftown hexa-core next year.
Want a mainstream quad? buy lynnfield at the end of this year and upgrade to Sandy Bridge at the end of the next year.
Are satisfied with your E8x00, or another dual core and think quad-core is a waste of money? Go for Clarckdale at the end of this year.
Want to buy a notebook? The 32nm Arrandale will deliver excellent performance with great power savings and an on package graphics processor for even more power saving.
Want to buy a powerful quad-core notebook? Go for Nehalem based Clarcksfield 45nm, which should deliver quite a lot of performance over current mobile CPU's, with Nehalem's power saving features as well, but not as much power savings as Arrandale.

I'm a bit dissapointed that the next top of the line chip will be 6-core instead of a pumped quad. We are still in multi-core infancy with very few programs taking advantage of anything over dual-core, and almost nothing taking FULL advantage of quad-core. I just don't see how 6-core will be more beneficial than a higher clocked 4-core...As it stands, however, if the power efficiency is legit my next computer may very well be a laptop.
