Intel P45 / G45 Express Launch and Technology Preview

Technology Overview

Today at Computex, Intel has officially launched their updated lineup of x45-series chipsets, which will likely be the last major mainstream chipset launch from Intel on the Core 2 platform as we know it today. The names and specifications of these products have been rumored and reported on for the past few months, although today everything is set in stone and products are beginning to hit the market. The products which are launching today will make up the lion’s share of Intel’s chipset lineup until their next generation high-end X58 chipset launches with the Core 2’s successor, codenamed Nehalem.

While all of these new chipset products which are being launched today are based on the same core architecture, Intel has segmented this one architecture into four individual products. Those four products are the G45 Express, G43 Express, P45 Express, and the P43 Express. As implied by this naming schema, these four products are very close in terms of features, capabilities, and performance. The P45 and P43 products are the “high-end” and “low-end” models which do not have integrated graphics support, while the G45 Express and G43 Express are the “high-end” and “low-end” models which do have Intel’s new integrated graphics engine, the X4500 / X4500HD.

While it’s always exciting to see new chipset products launched from Intel, it’s important to keep in mind that this newly launched family of products is aimed at the mid-range market, replacing the Intel P35/G35 products which are out today. Intel is still keeping the X48 Express chipset as their high-end product of choice, whereas the G45/P45 series products will fall one notch below, bringing almost all of the features of this high-end product to a much broader audience. These newly launched chips will be the big-sellers which will be seen in most Intel systems throughout the next year.  Feel free to take a quick glance at how the specifications of these new chipset products line-up.
