Question: What was the lithography previous to 45 nm? Passage:The Intel Core microarchitecture (previously known as the Next-Generation Micro-Architecture) is a multi-core processor microarchitecture unveiled by Intel in Q1 2006. It is based on the Yonah processor design and can be considered an iteration of the P6 microarchitecture introduced in 1995 with Pentium Pro. High power consumption and heat intensity, the resulting inability to effectively increase clock speed, and other shortcomings such as an inefficient pipeline were the primary reasons why Intel abandoned the NetBurst microarchitecture and switched to a completely different architectural design, delivering high efficiency through a small pipeline rather than high clock speeds. The Core microarchitecture initially did not reached the clock speeds of the NetBurst microarchitecture, even after moving to 45 nm lithography. However after many generations of successor microarchitectures which used Core as their basis (such as Nehalem, Sandy Bridge and more), Intel managed to eventually surpass the clock speeds of Netburst with the Devil's Canyon (Improved version of Haswell) microarchitecture reaching a base frequency of 4 GHz and a maximum tested frequency of 4.4 GHz using 22 nm lithography.

question:
Question: How tall is Mount Weeks? Passage:According to the United States Census Bureau, the city has a total area of , of which is land and is water, comprising 1.35% of the city. Berlin is situated at the confluence of the Androscoggin and Dead rivers. The Mahoosuc Range is to the southeast. Jericho Mountain State Park, created from a city park and from private land in 2005, is west of the city center and features a reservoir created in the 1970s and a network of ATV trails. The city's highest point is Mount Weeks, at above sea level. A prominent feature in the landscape of Berlin is Mount Forist, rising over the west side of the city. Approximately half of Berlin lies within the Connecticut River watershed, and half lies in the Androscoggin River watershed.

Question: How many years after his first graduation did Kentridge receive an Honorary Fellow from Exeter College? Passage:Kentridge is a Knight Commander of the British Order of St Michael and St George (1999) and a Supreme Counsellor of the South African Order of the Baobab in Gold (2008). He has been awarded an Honorary LL.D. by the Universities of Leicester (1985), Cape Town (1987), Natal (1989), London (1995), Sussex (1997), Witwatersrand (2000) and Buckingham (2009). He was elected an Honorary Fellow of Exeter College, Oxford – his alma mater – in 1986. He is also a Fellow of the Institute of Advanced Legal Studies (1997), an Honorary Fellow of the American College of Trial Lawyers (1998) and an Honorary Member of the New York City Bar Association (2001). In March 2013, Kentridge was interviewed on the British radio show Desert Island Discs. In May 2013, he received a lifetime achievement award at the inaugural Halsbury Legal Awards. The South African General Bar Council awards an annual prize in Kentridge's name, the Sydney and Felicia Kentridge Award, for excellence in public interest law.
