One of the highlights at the IDF today is Intel's upcoming Core i7 architecture:
Nehalem Microarchitecture spanning a range of products – The Intel® Core™ i7 processor and a variant designed for the efficient performance server segments codenamed “Nehalem-EP” will be the first segments of the Nehalem microarchitecture in the market. A derivative designed for the expandable sever market (“Nehalem-EX”) as well as the desktop and mobile versions (“Havendale,” “Lynnfield,” “Auburndale” and “Clarksfield”) will be in production in the second half of 2009.
Here are some of the technical disclosures Intel made about Nehalem:
Turbo Mode – In response to workload demand, adds higher speed to active cores.
Power Gates – Enabled by Intel in-house design and process technology. Turns individual cores on/off. Transparent to OS. Ultra low leakage. Cores can run at independent voltage/frequency.
Intel Hyper-Threading Technology – New and improved with more processor resources.
Over 3X increase in memory bandwidth
Almost 2X increase in 3-D animation performance
Intel Core i7 and X58 Chipset – Production Q4, 4 cores – 8 threads with Hyper-Threading, turbo mode, 8MB of Intel Smart Cache, QuickPath, integrated 3 channel DDR 3 memory controller, PCI Express 2.0
Intel also talked about Calpella and Piketon:
Calpella and Piketon 2009 Platforms – Two chip solution. CPU has integrated memory controller and optional graphics version. IBEX Peak, centralized platform capabilities
