Intel's X38 refresh appears on its latest roadmaps

A memo forwarded to DailyTech reveals that Intel's X48 chipset has been added to the company's roadmap. The X48 is an updated version of Intel's X38 chipset, which was released by Intel a little over two weeks ago.

The Intel X48 chipset features support for Intel Core 2 Duo, Core 2 Quad, and Core 2 Extreme processors. In additon, the chipset also supports Intel's Wolfdale and Yorkfield processors, which are yet to be released.

For those of you who have been paying attention, you'll notice that all of the features named so far are also present on Intel's X38 chipset. In fact, the only real new feature that the Intel X48 comes with is support for 1600MHz front side bus. As of right now, Intel doesn't plan for any other new features.

Intel previously launched its X38 chipset on October 10, 2007. The chipset had been delayed a number of times due to manufacturer support. As of right now, availability of Intel X38-based boards is still scarce.

Those looking to purchase Intel's 1600 MHz front-side bus 45nm Penryn processors in November will have to use a server-based platform, Skulltrail, to take full advantage of the increased bus speed.

Intel has so far not set a solid NDA-lift date for its X48 chipset other than the vague indication that the chipset will be announced in Q1 2008.

After the X48 launch, the company will also release two last LGA775 chipsets: P45 and G45, in Q2 2008.  These chipsets will feature Intel's updated southbridge (ICH10) and support for 1600 MHz front-side bus.  However, these new chips are not compatible with LGA1366 Nehalem desktop processors, which are slated for release in Q4 2008.

RE: Yet another advantage to intel...

Interesting thoughts. Just wanted to point out that the northbridge does a lot more than just handle CPU-memory communications, so saying that AMD sells the northbridge as part of the CPU is a bit wrong.

Granted. However, the memory controller is probably the most R&D intensive part of the north bridge, and the single largest factor affecting performance (Aside from GPU). Added to this is the fact that with the AMD CPU architecture it's extremely simple to pair up a single (or multiple) chip(s) to the HT link provided. The simplified NB / SB, or Single Chip is still cheaper, and / or able to provide more functionality for a given die size. More PCI Express lanes, more transistors for GPU, UVD, etc. Either way, platforms giving x feature set, or x performance remain cheaper.

(In essence a plain NB for this platform could simply be a PCI-express implementation with PCI-Express to HT bridge; Something quite simple to toss onto a SB, or "insert name here" system silicon.)

However, in modern terms for NB functionality, you are right. (Is a Colbert-esque tip of the hat suitable?)

Have a good night.
