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

Tick-Tock: U R Doin it Right
Let’s check the stats; Conroe in July 2006, Penryn in October 2007, Nehalem in November 2008. That’s a tock, tick, and another tock, each about a year apart. Note that the cadence does appear to be slipping a bit, but we’ll see exactly when in 2009 we get Westmere before making any accusations.
The next tick is, as I just mentioned, Westmere. It’s a 32nm shrink of Nehalem, much like Penryn was a 45nm shrink of Conroe/Merom. And it’s due out in the fourth quarter of this year.
Yesterday, Intel demonstrated working versions of its 32nm processors in both desktops and notebooks. The notebook aspect of the demonstration is very important, which I’ll get to later. Both mobile and desktop versions of Westmere will be shipping from Intel in Q4.
Getting Complicated with Code Names
Nehalem is the overall name for Intel’s 45nm desktop/mobile/server product family. At the high end we have Bloomfield, which is the quad-core, eight-thread, Core i7 processor we all long for. That’s the only Nehalem derivative that’s launched thus far.
| Segment | Manufacturing Process | Socket | Processor | Cores | Threads | Release Date |
| High End Desktop | 45nm | LGA-1366 | Bloomfield | 4 | 8 | Q4 2008 |
| Mainstream Desktop | 45nm | LGA-1156 | Lynnfield | 4 | 8 | 2H 2009 |
| Mobile | 45nm | mPGA-989 | Clarksfield | 4 | 8 | 2H 2009 |
| 4S Server | 45nm | LGA-1567 | Nehalem-EX | 8 | 16 | 2H 2009 |
| 2S Server | 45nm | LGA-1366 | Nehalem-EP | 4 | 8 | 1H 2009 |
| 1S Server | 45nm | LGA-1156 | Lynnfield | 4 | 8 | 2H 2009 |
By the end of this year we’ll see Lynnfield and Clarksfield. These are both quad-core, eight-thread Nehalem processors but at lower TDPs and price points. They will fit into Intel’s unannounced LGA-1156 socket and only support two channels of DDR3 memory (compared to LGA-1366 and 3-channels with Core i7).
On the server side we’ll have Nehalem-EX, an 8-core, 16-thread version. Nehalem EP a 4-core, 8-thread version. And Lynnfield again for the entry level servers.
These are all 45nm parts and all due out by the end of this year.
Note that there’s one name missing: Havendale. Havendale was supposed to be a 2-core Lynnfield + on-chip graphics, perfect for notebooks and low end desktops where quad-core isn’t necessary. Unfortunately, Havendale got delayed until Q4 2009 with systems shipping in Q1 2010. That just happened to coincide with Intel’s 32nm ramp so a very significant decision was made: Havendale got scrapped.

For the CPU market, the problem is the ever growing amount of cache memory. Intel processors are designed with the large cache being their solution to improvements that AMD brings to the table.I suspect that Intel will have more trouble after this move to the new fab process because the difficulty in moving to a new process node grows at an exponential rate. We saw Intel hit a wall with the Pentium 3 line because they were not ready for a new process shrink at that point, so the P4 came out. When Intel got their process technology on track, the people at Intel could go back to the Pentium 3 design(with improvements) to release the Core and Core 2 Duo.
There will come a time when an all new design will be needed in order to hold on to their lead, and that is when AMD will probably catch back up, if AMD can survive until then.

What an utter load of BS. Thanks fanboy.You get all that from wiki?

Even though my last three CPUs were all from AMD (they made sense at the time- K6-III/400, Athlon XP 1700+, Athlon 64 X2 4400+), I have to disagree with your comment about the improvements (presumably the integrated memory controller) which AMD brings to the table.With Core i7, Intel has effectively removed the one last technological advantage AMD had- faster memory access. The fact that Intel chips still tend to have larger L3 caches is quite simply because they can afford to give it to them, as they are ahead of AMD on the fab-process. For a high-end desktop chip where there is die-space to spare, you could add some more cores which will probably sit idle (keeping four busy is hard enough, especially with HT), but adding more L3 cache (so long as the latency of it is not adversely affected) is a very cheap and easy way to use up the space and provide a bit of a speedup in almost everything.
AMD is currently fighting a losing game. The Phenom II (bug-fixed Phenom) cannot compete with Core i7 with AMDs current fabs, and unlike Intel who have the tick-tock steady new-process, then new-design with large teams working on each step; AMD seem to have one team working on a new design, which has to be made to work with whichever process looks like the best option at the time.
We need AMD to survive for the x86 (or x64, who came up with that :p ) CPU market to be competitive, but I think the head of AMD is going to have to get into bed with the head of IBM, else they are doomed to fall ever further behind Intel in chip-design. The K10 is promising, but a long way off still, and AMD hasn't exactly been raking in the billions of dollars of profits recently to do that R&D. VIA have found an x86 CPU niche they can compete in, I fear that unless AMD pull an elephant out the hat with the K10, they'll have to slot in between VIA and Intel in providing CPUs specialising in a particular performance-sector, with Intel being the undisputed leader.

Well said. I concur.
