This is just a rumor, but it would come as no surprise if it were true. The rumor is that Intel will be delaying the launch of it’s X48 chipset due to the fact that there is so much X38 stock available. Who didn’t see this coming? X38 was launched just in November, and X48 was due to launch in January. That is not exactly that much time to clear out a new product run.
Of course, X48 is not actually set to replace X38, except for the enthusiast market. X48 will not be available in “budget” motherboards, but is rather designed solely for the enthusiast, which is backed up by it’s native 1600FSB support. In the end, if there is a delay, it will not hurt anyone. Both X38 and X48 are so similar in spec, there is no sense waiting around until X48 arrives if you are planning a purchase.
The motherboard maker fears that the X48 chipset will slow down clearance of its X38 chipset inventory and has negotiated with Intel to delay the launch of its X48 chipset. However the delay is expected to hurt makers who do not have an overstock X38 chipsets.
