アナリストから見たDell CEO交代劇 http://www.eetimes.com/news/latest/showArticle.jhtml;jsessionid=KXWWPVCZGWH52QSNDLSCKHA?articleID=197006371 There are other bad signs for AMD.''We see Michael Dell's return as CEO at Dell as a negative development with strong ties to Intel,'' he said. ''OEM relationships are straining to stay engaged with AMD at this time given its stale product line-up. We continue to think AMD needs to get new products out to regain a competitive stance.''

http://www.eetimes.com/news/semi/showArticle.jhtml?articleID=198100278 Intel CEO Paul Otellini told partners Monday that the company now has five 45-nm processors running on six operating systems: a notebook dual-core processor, dual- and quad-core desktop processors, and dual- and quad-core DP server processors.
"The new UltraMobile CPU is in addition to the first five," he said. "The first UltraMobile devices we'll see in the latter part of the year."
最初のCSIは銅配線? >Realistically, I don't see a way that the first iterations of CSI could be optical. >This optics break through was very recent - and I'm pretty darn sure the first products using CSI had already taped out by then. >I don't see a reason why either. As I mentioned, copper's fine for the data rates that CSI will run at, both initially, and over the course of the following 4 years (I'm assuming a start at 6.4gbps and climbing to ~20gpbs after 4 years).
45nm?32mn?22nm?MCP? >The reality is that CSI won't be optical at 45nm, because Intel isn't using the right materials. >Everyone who works with optical stuff uses SOI. Bulk silicon just doesn't have the right properties AFAIK. > >Intel has said they might consider SOI or other materials at 32nm, but not 45nm. >Alternatively, I suppose they could do a MCP, where one chip is the optical interface to the outside world, which is connected to the MPU by a very very very high speed copper interface.
チラ裏 >Optimal wavelength for silicon is around 1330nm >When using a InP coupled to Si structure, about 80% of the light from the InP will go to the lasing chamber (requires SOI silicon)

http://www.realworldtech.com/page.cfm?NewsID=370&date=03-28-2007 >However, Penryn is not just a shrink to 45nm, there are several specific enhancements to improve performance. According to Intel, > their initial performance analysis shows that a 3.2GHz Penryn system using a 1.33GHz front-side bus is 20% faster on gaming workloads than the current high-end 2.93GHz Conroe with a 1.03GHz bus. >For more bandwidth and floating point intensive workloads, Intel claims that a 3+GHz quad core based on Penryn, with a 1.6GHz bus will see a 45% improvement relative to a 2.67GHz/1.33GHz Clovertown server system. >This is most likely measured using the SPECfp_rate 2006. 最初のシリコンが2GHz超で動作しただけに、既に3.2GHzで動いているのか、それともシミュレーションなのか興味深いところ。 後者の45%は単なる想定値っぽいな…

Penrynのダイサイズは107平方mm。
>Finally, Intel mentioned that in the server space, the fastest quad core Penryn available (>3GHz) vs. a 2.67GHz quad core Xeon resulted in a greater than 45% increase in performance in "bandwidth and FP intensive applications". >It's incredibly vague (and oddly similar to AMD's claims of Barcelona vs. Xeon performance), but Pat mentioned that STREAM and certain benchmarks in SpecFP could be considered to be "bandwidth and FP intensive". 3GHz以上のPenrynはメモリインテンシブなアプリでClovertown 2.67GHzと比較して45%性能が向上。 Penrynのスペックが曖昧すぎる上にAMDのClovertownに対する主張と同じなので話半分に聞いておけ、と。

The Long Awaited Penryn Update http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=2968&p=2 Finally, with regards to motherboard support, Intel isn’t making any guarantees about Penryn’s backwards compatibility. While Penryn will still use the LGA-775 socket that Prescott and Conroe have used, motherboard support will require more than just the presence of the socket. If the appropriate VRM spec is implemented, then Penryn will work on your LGA-775 motherboard, the problem is that motherboard manufacturers haven’t yet released information on which of their boards will support the Penryn VRM changes. If history repeats itself, you can expect very limited official support for Penryn in currently shipping motherboards and guaranteed support with boards based on Intel’s new 3 series chipsets (e.g. P35). We did see Penryn up and running on an Intel BadAxe2 board, but it had a hardware VRM modification done to it in order to properly support Penryn. Penryn may also be able to work on boards without a VRM mod, however at increased (potentially out-of-spec) voltage settings.

NMI-window exitingの説明 http://www.intel.com/technology/itj/2006/v10i3/1-hardware/8-virtualization-future.htm ・NMI-window exiting. The interrupt-window exiting VM-execution control (described earlier) causes a VM exit when a guest is ready for maskable external interrupts, allowing a VMM to deliver such interrupts in a timely way. NMI-window exiting provides corresponding support for non-maskable interrupts (NMIs), which are blocked by other conditions than those that block maskable external interrupts.
