The Inq has seen roadmaps of Intel's upcoming server chips:
The prices for Tulsa, with an estimated shipping date in Q4 of 2006, are $3160 for the 7140M and the 7140N, $1980 for the 7130M and the 7130N, $1180 for the 7120M and the 7120N, and $850 for the 7110M and the 7110N.
What's all this M and N thing about, you are probably asking? The M suffix denotes 150W chips using an 800MHz bus, and the N suffix the 95W family using a 667MHz bus. There are also clock speed differences between the Ms and the Ns which also have different cache sizes.
The 7140M is a 3.40GHz 16MB part, the 7140N is a 3.33GHz, 16MB part. The 7130M is a 3.20GHz, 8MB part, while the 7130N is a 3.16GHz 8MB part.
The 7120M and the 7120N have 4MB of cache and clock at 3GHz respectively. The 7110M and the 7110N clock at 2.60GH and 2.50GHz respectively, and have 4MB of shared cache.
