Poulson information from Intel’s ISSCC Paper • Intel presented a paper on Poulson at the International Solid-State Chips Conference (ISSCC) in July 2011. From this, we learned: • Poulson would be in a 32 nm process (2 process generations ahead from Tukwila, which was at 65 nm, skipping the 45 nm process) • The socket would be compatible with Tukwila • Poulson would have 8 cores, of a brand new core design • The front end (instruction fetch) would be decoupled from the back end (instruction execution) • Poulson could execute and retire as many as 12 instructions per cycle, double Tukwila’s 6 instructions http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/itanium-poulson-isscc-paper.pdf 6 © Copyright 2015 Hewlett-Packard Development Company, L.P.

  • Replace Nine Older Servers with One Dell Emc Poweredge Vrtx
    COMPARING PERFORMANCE AND COST: DELL EMC POWEREDGE VRTX WITH ONE DELL EMC POWEREDGE M830 SERVER VS. A LEGACY SOLUTION Businesses using multiple outdated server0 sSERVER for email, database, NODES and fileVS. and A LEGACY SOLUTION print workloads stand to benefit greatly by consolidating these workloads onto a single new server and running them in virtual machines. In tests in the Principled Technologies datacenter, the Dell EMC PowerEdge VRTX with a Dell EMC PowerEdge M830 blade server, powered by the Intel Xeon processor E5-4650 v3, was able to simultaneously run email, database, and simulated file and print workloads in a VMware® vSphere® virtual environment. The VRTX performed the work of nine older servers—four database servers, four file and print servers, and one Exchange server. It achieved similar or even better performance while requiring less space and power than a legacy disparate hardware solution,1 which translates to a lower five-year TCO. Combining servers, networking, and shared storage into an all-in-one solution, the PowerEdge VRTX can deliver big performance and savings. 1 In June 2013, Principled Technologies conducted testing comparing the performance of (1) the Dell PowerEdge VRTX with a Dell PowerEdge M620 server and (2) a legacy hardware solution. The results for the legacy solution that we cite in this report are from that earlier study. For more details, see the report for that study, available at www.principledtechnologies.com/Dell/VRTX_performance_TCO_0713.pdf. JULY 2015 (Revised January 2017) A PRINCIPLED

  • A 65 Nm 2-Billion Transistor Quad-Core Itanium Processor
    18 IEEE JOURNAL OF SOLID-STATE CIRCUITS, VOL. 44, NO. 1, JANUARY 2009 A 65 nm 2-Billion Transistor Quad-Core Itanium Processor Blaine Stackhouse, Sal Bhimji, Chris Bostak, Dave Bradley, Brian Cherkauer, Jayen Desai, Erin Francom, Mike Gowan, Paul Gronowski, Dan Krueger, Charles Morganti, and Steve Troyer Abstract—This paper describes an Itanium processor imple- mented in 65 nm process with 8 layers of Cu interconnect. The 21.5 mm by 32.5 mm die has 2.05B transistors. The processor has four dual-threaded cores, 30 MB of cache, and a system interface that operates at 2.4 GHz at 105 C. High speed serial interconnects allow for peak processor-to-processor bandwidth of 96 GB/s and peak memory bandwidth of 34 GB/s. Index Terms—65-nm process technology, circuit design, clock distribution, computer architecture, microprocessor, on-die cache, voltage domains. I. OVERVIEW Fig. 1. Die photo. HE next generation in the Intel Itanium processor family T code named Tukwila is described. The 21.5 mm by 32.5 mm die contains 2.05 billion transistors, making it the first two billion transistor microprocessor ever reported. Tukwila combines four ported Itanium cores with a new system interface and high speed serial interconnects to deliver greater than 2X performance relative to the Montecito and Montvale family of processors [1], [2]. Tukwila is manufactured in a 65 nm process with 8 layers of copper interconnect as shown in the die photo in Fig. 1. The Tukwila die is enclosed in a 66 mm 66 mm FR4 laminate package with 1248 total landed pins as shown in Fig.

  • Evolution of the Pentium
    Chapter 7B – The Evolution of the Intel Pentium This chapter attempts to trace the evolution of the modern Intel Pentium from the earliest CPU chip, the Intel 4004. The real evolution begins with the Intel 8080, which is an 8–bit design having features that permeate the entire line. Our discussion focuses on three organizations. IA–16 The 16–bit architecture found in the Intel 8086 and Intel 80286. IA–32 The 32–bit architecture found in the Intel 80386, Intel 80486, and most variants of the Pentium design. IA–64 The 64–bit architecture found in some high–end later model Pentiums. The IA–32 has evolved from an early 4–bit design (the Intel 4004) that was first announced in November 1971. At that time, memory came in chips no larger than 64 kilobits (8 KB) and cost about $1,600 per megabyte. Before moving on with the timeline, it is worth recalling the early history of Intel. Here, we quote extensively from Tanenbaum [R002]. “In 1968, Robert Noyce, inventor of the silicon integrated circuit, Gordon Moore, of Moore’s law fame, and Arthur Rock, a San Francisco venture capitalist, formed the Intel Corporation to make memory chips. In the first year of operation, Intel sold only $3,000 worth of chips, but business has picked up since then.” “In September 1969, a Japanese company, Busicom, approached Intel with a request for it to manufacture twelve custom chips for a proposed electronic calculator. The Intel engineer assigned to this project, Ted Hoff, looked at the plan and realized that he could put a 4–bit general–purpose CPU on a single chip that would do the same thing and be simpler and cheaper as well.
