The Lynnfield Preview: Rumblings of Revenge

Lynnfield Pricing and Specs
From Intel’s first disclosure of Nehalem we knew that the architecture, albeit optimized for quad-core processors, would scale up to 8 cores and down to 2:
Lynnfield, however, does not scale Nehalem’s core count in any direction. The eight-core derivative is Nehalem-EX and the two-core versions will appear later this year in 32nm mobile form. Lynnfield is a direct replacement for the quad-core Penryn CPUs that have dominated the market for the past year and a half.
| Name | Manufacturing Process | Cores | Target Market | Release |
| Gulftown | 32nm | 6 | High End Desktop | 1H 2010 |
| Core i7 (Bloomfield) | 45nm | 4 | High End Desktop | Q4 2008 |
| Lynnfield | 45nm | 4 | Performance Desktop | Q3 2009 |
| Clarksfield | 45nm | 4 | High End Mobile | Q3 2009 |
| Clarkdale | 32nm | 2 | Mainstream Desktop | Q4 2009 |
| Arrandale | 32nm | 2 | Mobile | Q4 2009 |
A few places have published rumored Intel roadmaps for Lynnfield, indicating that three Lynnfield chips will be launched in the second half of this year:
| Model Number | Clock Speed | Cores / Threads | Maximum Single Core Turbo Frequency | TDP | Price |
| ? | 2.93GHz | 4 / 8 | 3.60GHz | 95W | $562 |
| ? | 2.80GHz | 4 / 8 | 3.46GHz | 95W | $284 |
| ? | 2.66GHz | 4 / 4 | 3.20GHz | 95W | $196 |
All of the processors are quad-core Nehalems with the same cache sizes as the Core i7. The only crippled beast is the entry level Lynnfield that has Hyper Threading disabled. Note the ridiculously high turbo frequencies which are, I believe, Lynnfield’s secret weapon.
| Processor | Price |
| Intel Core i7-940 (2.93GHz) | $562 |
| Intel Lynnfield 2.93GHz | $562 |
| Intel Core i7-920 (2.66GHz) | $284 |
| Intel Lynnfield 2.80GHz | $284 |
| Intel Lynnfield 2.66GHz | $196 |
| Intel Core 2 Quad Q9650 (3.00GHz) | $316 |
| Intel Core 2 Quad Q9550 (2.83GHz) | $266 |
| Intel Core 2 Quad Q9400 (2.66GHz) | $213 |
| Intel Core 2 Quad Q8400 (2.66GHz) | $183 |
| Intel Core 2 Quad Q8200 (2.33GHz) | $163 |
With a 2.66GHz Lynnfield and a $100 P55 motherboard you now have the ability to deliver a good quad-core system at around $150 - $200 cheaper than the cheapest Core i7. Price-wise the 2.66GHz Lynnfield would be priced cheaper than today's Core 2 Quad Q9400, and as you'll see Lynnfield is clearly a faster bet.
The 2.80GHz Lynnfield should also be able to outperform the i7-920 without a problem, at a lower total system cost as well.

Why is it that in test that demand intensive multi threading, the lynnfield loses out to bloomfield while in less intensive multithreaded or single threaded test, the lynnfield can equal bloomfield? Could it be that in intensive multithreading processing that work up more than 4 threads (thereby requiring the use of HT for better performance), it is able to use the extra memory bandwith provided by triple channel in the bloomfield platform? Maybe in situation where the software can really demand mutlple threading processing intensively, the bloomfield extra memory bandwith provide an edge. An easy way to test this is increasing the memory bandwith of lynnfield and/or decreasing memory bandwith of bloomfield n see wht happens in intensive multithreaded test. Im suspicious of this. Let me know wht u guys thinks.IntelUser2000 - Sunday, May 31, 2009 - link
The Turbo Modes for revealed for Lynnfield way before even Core i7's release.1 core: +5(+4 for non-HT version)
2 core: +3
4 core: +1
It may or may not be coincidence, but the Turbo speed of the highest clock Lynnfield is equal to the Turbo speed of the highest Core i7. The point is, I think since people will overclock the "enthusiast" i7's anyway, the Turbo doesn't need to be so high.
According to Intel, the benefits will be GREATER on smaller form factors, which means laptops will have even HIGHER increases.

Hmmm... I'm not sure how much sense Lynnfield will make in the long term - at the high end you'll have Bloomfield on LGA-1366, and at the low end Clarkdale/Arrandale on LGA-1156. I'm not sure if there's enough room between them for Lynnfield, though I guess it does provide an easy upgrade option for inexpensive OEM systems which need to support Clarkdale.brightstar - Sunday, May 31, 2009 - link
I'll wait and see how this pans out, but as of right now the I5 sounds like the new Celery proc to meJS - Saturday, May 30, 2009 - link
"...to protect the innocent"I guess you really wanted to say "to protect my sources". I'm guessing they are not innocent at all, unless you actually stole the stuff from them. ;o)

The article mentions that Lynnfield will have a new turbo mode that clocks much higher. I was thinking of reasons why intel might put this feature into the mainstream i5 rather than making the feature exclusive to the i7. Then I remembered that the PCIe controller was integrated into the core.To overclock a multiplier locked i5, you would have to increase the base clock. Not sure, but I believe this would also overclock the PCIe controller (something which may not be as tolerant of overclocking).
This might explain why the new high end turbo mode would be included in the i5. You lose high overclocking potential (which would attract overclockers to i7), but in exchange, the i5 does decent overclocking for you.

is it possible that we will see turbo modes similar to lynnfield in gulftown? also, is intel going to release any 8 core / 16 thread nehalem processors targeted towards desktop systems or is the nehalem-ex likely to be the only 8 core nehalem we will see?mmpalmeira - Saturday, May 30, 2009 - link
Why did you use the Lynnfield in a 2.66Ghz configuration with HT on if there wont be models like that in the market?Anand Lal Shimpi - Saturday, May 30, 2009 - link
I did that to show what sort of performance having HT enabled is responsible for. Intel isn't making a 2.13GHz HT enabled Lynnfield either, but I ran those tests because they're interesting to look at :)Take care,

Will the P55 support USB 3, SATA 3, UEFI?When will we see all those features in the chipsets, which for me, are much more important than the i5 by itself.
What about the new Chiopsets, are they SSD optimized?
