Intel Nehalem Photo debut

sums everything up nicely

Lynnfield and Havendale have no QPI because they have nothing to talk to with it. The memory controller and northbridge are all integrated on die. The only external things that the chips talk to is the memory and the Ibex Peak PCH that does all the normal southbridge tasks.

can someone shed some light for me regarding the 2 and 3 ch ddr3 setup?

1. why is the 2 ch coming out later, seems to me that would be the lower
performing one.

2. i take it the 2 ch does not relate to dual channel and 3 ch to triple
channel, if so why ddr3 dual channel, wasen't the hole point of goin to ddr3
to get an additional channel besides the change of memory access pattern?

thanks

btw, i wish they were here next week. a whole year of waiting

1. Intel makes much more money and creates more orders of following products by making a strong showing in the server market and the enthusiast market. It also takes a bit longer to validate to the server market and that process will drive most of the changes in prodruct revisions as it is the most sensitive to errata.

2. DDR2 can do dual channel, triple channel or any numbers of channels. the recent change is not due to the shift to DDR3, but the limitation of the current memory controller architecture. The new IMC's have been setup to deal with more channels.

i heared bloomfield first, which supposedly is the most expensive platform with tylersburg chipset / QPI and triple channel ddr3

yup

Lynnfield (performance/desktop) and Havendale (integrated graphics core) later with dual channel ddr3 and ibexpeak PCH.

yup

and i also thought all 3 had integrated mem. controllers

yup

also heard rumours that there will be a dual core nehalem; a 775 nehalem; with and or without imc... and a variant to support ddr2 aswell; and a kitchen sink codenamed nehalem also

Havendale is dual core. No 775 support, and only one i know of is MP servers with FB-DDR2

IMC is supposedly only for server and enthusiast chips.

nope all of them have IMC, some only have 2 channels, and not all of them need QPI

its rather simple, instead of intel manufacturing non QP and non triple channel ddr3 they will just use the chips that "fail" which takes time to accumulate enough to supply the market. It always works that way, all manufacturers will spin for the best silicon and parts that don't meet the cut will trickle down to supply the mainstream........nvidia,ati and amd all do this.....

Right now I'm willing to bet that intel is only manufacturing QX quads, failed cache's = regular quads, failed cores = core 2 Xtremes, failed cache and cores = c2d, failed c2d cache = c2 celerons, failed c2d cores = single core celerons..............It's just a big domino effect, $hit rolls down hill.............

Not reallly, for nehalem everything is pretty much it's own product just binned to run at different speeds. Sure some of the failed quad chips may end up down lower, but we would much rather make 200 quality dual cores on a wafer as a seperate product, then count on having a product that only has 100 on a wafer to have lots of bad chips. wafer space is expensive real estate.
