Intel to put Westmere desktop chips in servers
Intel has tweaked its chip road map, with plans to extend its upcoming Westmere mainstream desktop dual-core chips with integrated graphics processors to entry-level servers.

Intel has made a number of power-saving enhancements to its Atom architecture that will be included in its upcoming Moorestown platform for smartphones, a company official said on Monday.
Intel and Micron Technology have developed a new 3-bit-per-cell, NAND flash memory technology using Micron's 34-nanometer lithography process.
Intel has confirmed that its new consumer-class X25-M and X18-M solid state-disk drives (SSDs) suffer from data corruption issues and says it has pulled back shipments to resellers.
Collaboration with Microsoft could allow the software giant's upcoming Windows 7 OS to take advantage of multithreaded and multicore Intel chips for faster application performance, according to an Intel official.
Intel has launched new solid-state drives that are cheaper and have faster write speeds than their predecessors, the company said Tuesday.
The world's largest chip maker is working with Google on the Chrome operating system and has been privy to the project for some time, a spokesman for the company said.
Intel has reported its net income for the second fiscal quarter of 2009 dropped US$2 billion year-over-year because of the hefty fine imposed on the chip maker by the European Commission.
The world's largest chip maker is working with Google on the Chrome operating system and has been privy to the project for some time, a spokesman for the company said Friday.
Much of the discussion around Google's new PC operating system has focused on a looming battle with Windows, but the biggest losers could be other Linux OSes that have been enjoying some moderate success on netbooks, industry analysts said.
It seems Moore's Law doesn't apply to the next generation of Intel's Atom chips. The low-cost, power-sipping chips, codenamed "Pineview," will greatly improve upon both of those traits, but at the expense of any significant speed boost, according to authentic-looking specs leaked this month.
After multiple delays, Intel on Thursday once again pushed back the release of its next-generation Itanium server chip to the first quarter of 2010.
Intel intends to appeal the European Commission's 1.06 billion Euro (NZ$2.43 billion) fine for anticompetitive behaviour in the chip market, with CEO Paul Otellini arguing that the EC "ignored or disregarded" evidence "refuting" its judgment.
Microsoft will take aim at IBM Thursday in a Web campaign touting Windows Server on Intel-based hardware as a better, more economical performer than IBM's AIX and RISC server platform.
When I first heard "Nehalem", it called to mind the noise that Felix Unger from "The Odd Couple" made to clear his sinuses. If Intel gets its way, its Nehalem CPU and system architecture will have a similar effect on the clogged-up market. I'm hoping it will clear bogged down workloads. It's not that we're suffering mightily with the likes of Intel Core 2 Duo and AMD Opteron Shanghai and Phenom II, but it's time we were rocked by something bigger than a speed bump.
Nehalem isn't strictly new, but I hung back until I could see it in a 2P platform (meaning two CPUs, or two sockets, if that's clearer) that shows it to its best advantage. An early look at such a platform is generally supplied only by the chipmaker itself, with one exception: Apple. It's the only first-tier system maker that's willing to have its high-end machines held up as exemplars of a CPU or system architecture, knowing that, in stories like this one, the architecture is given higher billing than the system itself.
2P Nehalem came to me in the guise of Apple's eight-core Mac Pro. OS X's Activity Monitor shows a pair of Nehalems as a 16-core CPU. Hyper-Threading has returned to the x86, but its role and potential are much changed since it went into rehab after the fall of Pentium IV. With a smart OS scheduler and some smart programmers, Hyper-Threading could do some real damage this time around. You may recall that with single-core CPUs, Intel claimed that Hyper-Threading was capable of boosting performance up to 30%. Apple's published benchmarks show that an eight-core Nehalem, running at 2.9GHz, bests its prior 3GHz, eight-core Mac Pro. By my rough weighted averaging and using Apple's own numbers (not mine; that comes next), Nehalem turns in 60%-70% higher numbers.
Taking on faith that Apple's numbers are accurate — after taking heat for past sins, they tend to be — I'm left to wonder where Nehalem gets that extra performance. Perhaps it draws some from Hyper-Threading. Some of it unquestionably comes from DDR3 memory, the next step up from DDR2, which is the prevailing standard. AMD criticizes DDR3's higher latency, saying that comparing fast DDR2 to DDR3 is a wash. AMD asserts this while having DDR2 and DDR3 on its near-term roadmap. Nehalem's NUMA (Non-Uniform Memory Access) architecture, which assigns independent banks of memory to each CPU, may counterbalance latency to some extent, the way it helps counterbalance lower cycle speeds on DDR2 with Opteron. Simultaneous memory access does that. It's my view that the Nehalem CPU's on-chip memory controllers and NUMA probably make a bigger difference than the kick up to DDR3. However the magic is done, Apple is claiming a 2.4X rise in memory throughput. I'd like to see that.
Nehalem also marks the return of the Level 3 cache that was present on some NetBurst Xeon CPUs. Level 3 cache is shared by all cores on a chip. Intel has always been a big believer in (big) cache, but I think it had pushed Core 2 Duo's shared Level 2 cache as far as it could go. Three-level cache is the right idea, and this also cuts down substantially on the number of cache probes the system does to make sure one core doesn't have a different picture of memory than another. The last of the significant improvements is TurboBoost. That's a technology to which I need to devote more study. By Intel's pitch, TurboBoost senses when tasks ordinarily spread across cores can be handled by fewer cores, potentially running at a boosted clock speed. Apple tells me that it'll be hard to see this in action with user-level facilities like Activity Monitor. Fortunately Apple and Intel supply tools that allow a closer look.
Nehalem begs for that closer look.
