One source is reporting that the new Tylersburg performance desktop chipset to be paired with Bloomfield will be marketed under the X58 name.
Is this really the go-to-market name for Tylersburg? Obviously, X58 is a natural progression from Intel's current enthusiast overclocking chipset the X38/X48 but given the radical architectural changes that will accompany Nehalem and Tylersburg, I'd be very surprised if the Intel marketing team didn't take this opportunity to be more creative and distinctive with the product nomenclature.
Here's the material from Expreview that lends some credibility to the report, but I wonder if this couldn't easily be a Photochop. Time will tell. (Click to enlarge...)
