Frys leaks Core i5 750

Frys.com claims that the Core i5 750 based on the upcoming Lynnfield core is in stock and ready for shipment.

Premature retailization is a serious condition.

Premature retailization is a serious condition.

The chip is not scheduled to launch until next month, but the 750’s star spangled appearance is second to China which has already bought and benched the part.

The Lynnfield family of processors comes as the budget-conscious alternative to the current crop of pricier Bloomfield Core i7 models. Based on the new LGA1156 socket, Lynnfield chips will launch with Core i5 (no HyperThreading) or Core i7 (HyperThreading enabled) branding.

The lower MSRPs for Lynnfield SKUs is largely owed to the removal of QuickPath Interconnect. QPI is Intel’s response to AMD’s HyperTransport, both of which offer high-bandwidth point-to-point links between the chipset or other CPUs. Lynnfield will instead use the simpler Direct Media Interface (DMI) to communicate with a unified core logic — dubbed the Platform Controller Hub (PCH) — which replaces both the northbridge and southbridge for the Lynnfield-only P55 chipset.

The reduction in memory controller and motherboard complexity is responsible for cost reductions which are being passed on to the consumer.

If your head is spinning over Intel’s decision to give budget parts the same branding as enthusiast parts, worry not. We’re totally right there with you.

    Do i5 and i7 use the same sockets?

  2. Lynnfield Core i5: LGA1156, p55 chipset
    Lynnfield Core i7: LGA1156, p55 chipset
    Bloomfield Core i7: LGA1366, x58 chipset

    Yeah, it's completely ridiculous. I was hoping that AMD's socket 939/754 shenanigans was the last we'd ever see of two sockets carrying the same branding.

    Guess not.

    That's not confusing at all!

    A quick google tells me the i7 920 was nehalem-based and also LGA1366. Kinda sucks for adopters of the 920, unless they're going to continue to make Bloomfield cores.

  4. Bloomfield is here to stay. Bloomfield is in every way faster than Lynnfield parts, which are only slightly faster than Core 2 Quads.

    X58 chipset production will continue into 2010, there are several new LGA1366 chips coming soon, and then Westmere will also fit into LGA1366.

    Lynnfield is not a replacement. It's just a stupid budget part. :/

    This is even less confusing! I suppose at least i5 < i7.

    I just bought an i7 920 and nearly had a heart attack reading this. But I should've known that Thrax wouldn't steer me wrong.

    I personally am hoping (best case) that the Lynnfield and Gulftown processors knock the price of the Bloomfield i7's down a peg or two. If I can build a bloomfield-based PC without spending more than $500 canadian on the mobo/CPU combo, I'll do it.

    Both Lynnfield and Clarkdale (as well as Havendale and the mobile versions of such: Clarksfield and Arrandale as well Auburndale) have QPI but they are internal and do not have any QPI signals that leave the processor packaging (the "dales" have two dies and the "fields" have one).

    The PCH only replaces the ICH south bridge--the north bridge is subsumed by the processor (including memory controller and graphics bus and even graphics controller in the "dales").

    DMI was used to connect north and south bridges in the past and now comes straight off the processor packaging to the PCH.

Hey, be nice. Icrontic is full of good people, we promise.
