Mobile Nehalem chips may come in late 2009


Intel is gearing up to release the first versions of its Nehalem chip family next month, with the scheduled launch of its Core i7 desktop processors. But users will have to wait much longer to get their hands on the mobile version of the new chip.

The mobile version of Nehalem, codenamed Clarksfield, will be in production beginning in the second half of 2009. . . .

Clarksfield will be produced using the same 45-nanometer production process that's used to make Intel's current chip lineup. The upcoming chip will be at the heart of the next version of Intel's Centrino laptop chip package, called Calpella.

Intel has done a great job in hiding the downside of its current quad-core architecture with fat on-die memory caches as well as the raw grunt of the Core 2 execution core. But as core counts rise, this approach would have become more and more of a boat anchor dragging down performance.

Consequently, all Core i7 chips will be monolithic in terms of the arrangement of the processor cores. At launch, Core i7 will be available in quad-core trim. An eight-core version is penciled in for next year and that too will have all its cores crammed into a single die.

Intel has had HyperThreading on the shelf and it was only a matter of time before it was re-introduced. In the Core i7 it's essentially the same technology as before and allows each core to process two software threads simultaneously for improved multi-threaded performance. With two threads per core, Core i7 chips will pack no less than eight logical cores at launch and 16 before the end of 2009.

Nehalem by the numbers: The Ars review


Nehalem hit the ground running last week, as benchmarks (both our own and others') showed that Intel's new Core i7 chews through most workloads in record time for a one-socket part, often besting dual-socket/octal-core Xeon configurations.

The new performance gap between Nehalem and pretty much everything else of comparable cost is the result of upgrades to both the CPUs core architecture and the platform on which the multicore chip now runs.

Because the Core i7 isn't just a "Penryn" Core 2 Duo with some L3 and an integrated memory controller, the present review focuses primarily on measuring how well Nehalem's performance scales in multithreaded workloads as compared to Penryn.

Making of Intel Core i7


Go inside the benchmarking lab in Santa Clara, California and in labs in Hillsboro, Oregon to see first-hand the enthusiasm, brilliance and dedication that went into creating the new Core i7 microarchitecture, codenamed Nehalem.

The Core i7 can handle more data, quicker and more energy efficiently. Building this microprocessor brings a lot of people together, like architects, micro architects and the design teams, says Rani Borkar, vice president of Intel's Digital Enterprise Group. As you get into the development phases, working with the process technology, it's a mind-boggling effort that requires a lot of teamwork across the board.

VERY cool Sid! You found my next box for me, but like Pooboy I think I'll give it a few months and read some reviews but yep! I think this is gonna be it!


Edit: oops! Just realized You said that not Poorboy! (Looking for a corner) Keep us posted on the reviews!

Sharky Extreme is reporting that Intel's new Core i7-965 -- the bottom-edge performer of its premiere trio of CPUs, at only 2.66 GHz -- has performance that is comparable with, in some cases virtually matching, Intel's current Core 2 Extreme 3.2 GHz QX9770 processor.

Why is that important? Because the QX9770 sells on the street today for $1,429.99, while the street prices for the first Core i7-920 are averaging right now at around $350.

Meanwhile, the 2.93 GHz Core i7-940 which very measurably outperforms the QX9770, sells on the street for about $680 on average; and the 3.2 GHz Core i7-965 Extreme sells today at right about $1,150.

So for about 24% lower price than Intel's top of the line last week, you can get a CPU that performs about 20% better.

Overclocking Core i7 920 on the ASUS P6T Deluxe


The P6T is ASUS' mainstream X58 board, but is well built. The BIOS setup has all the tweaking options we'd want. The P6T ships in two variants: the P6T and the P6T Deluxe / OC Palm. The two boards are essentially identical, with the OC Palm version shipping with a nifty external control unit that lets you adjust settings on the fly.

Dell Studio XPS: Intel's Core i7 system for £699


Intel knows that whilst Core i7 is damn good, gaining traction requires a tier-one box-shifter to sell systems at well under £1,000, and this is where Dell comes in.

Shipping the new technology in a mini-tower box, under the recently-released Studio XPS brand, Dell is currently etailing a full system, albeit base unit, for a staggering £699, including VAT and delivery.

Massive corner-cutting or incredible value for a new technology? Read on to find out....

How Windows Vista drags Core i7 down: Core i7's problem with Vista's thread management


At first glance, the combination of HyperThreading and Turbo Mode on the Core i7 processor looks like a winner. One ups the chip's multi-threading ante to frankly ludicrous levels, the other gives a helping hand to clunky old apps that haven't been coded to take advantage of modern multi-core CPUs.

Anyhow, during our Core i7 testing, we noticed some extremely odd behaviour in Task Manager. When running a single-threaded application, our 64-bit build of Vista was constantly shunting it from one core to another. The same is true when running two separate single-threaded applications at the same time. Vista continually juggles the threads among the available cores.

Big deal? Actually, it is. The problem with regard to HyperThreading is that Vista cannot tell the difference between a real physical core and a virtual core created by HyperThreading. Hence, as far as Vista is concerned, a system running the quad-core Core i7 looks like it has eight 'logicalCPUs', each of them equal.

Performance


The review Nehalem processor I was sent clocked in at a fairly zippy 3.2GHz. If it were a car, the Nehalem would have so much raw horsepower that Jeremy Clarkson would probably experience a spontaneous trouser accident. Some fearless geeks have already managed to overclock it to a positively searing 4.05GHz - this would leave Clarkson very red-faced, not to mention brown-jockeyed.

Benchmarking-wise, the single Nehalem powered motherboard came pretty close to wiping the floor with the SkullTrail motherboard which was powered by two 3.2GHz Core 2 Quad QX9770 CPUs.

Putting the Core i7 through its paces with Sisoft Sandra's benchmarking application saw it score an astonishing 102530, which is only marginally slower than the 116498 scored by the Skulltrail.

Considering that that the Nehelem's score was achieved with only half the processor cores of the Skulltrail, this is very impressive indeed.

In real world use, the Nehalem cut through CPU intensive tasks such as re-encoding video like a knife through hot butter, barely breaking a sweat in the process.

First look: Intel dual- socket Nehalem EP benchmarked: Xeon platform is ridiculously fast - we have the proof


Intel's new Nehalem-based Core i7 desktop processor is nippy. And now we can exclusively reveal that the upcoming dual-socket server variant of the Nehalem architecture is so fast it's almost silly.

In other words, as good as AMD's new Shanghai chip is, it appears that Nehalem EP will slap it around with a wet fish.

Just to confirm that our eyes did not deceive us, we also gave Nehalem EP a quick going over with the Stars Euler3D benchmark. It's a computational fluid dynamics simulation that majors on floating point performance.

Sure enough, Nehalem EP roasts all comers in this benchmark, too – it's twice as quick as a pair of 2.7GHz Shanghai processors (14.34 seconds to complete five instances versus 30.32 seconds).

Oh, and the platform's memory bandwidth is borderline biblical, clocking up 35GB/s in SiSoft Sandra's quick and dirty bandwidth benchmark.

Intel's Core i7 Extreme Edition 965 overclocked to 5.5GHz


Right, so Intel's 3.73GHz Core i7 Extreme Edition 965 is fast enough for the vast majority of PC users across the globe, but not for Japanese overclocking enthusiast duck.

Oh no -- duck decided to pair the chip up with ASUS' ROG Rampage II Extreme motherboard, which facilitates hardware-based OC'ing, in order to reach a top speed of 5510.09MHz.

was about to be expected - any intel-quad can be overclocked by 40% with decent cooling.
we will see cryo-cooled I7s @ 6 Ghz soon...

I've got the Parts to put mine together but I've been Procrastinating a usual & haven't got around to it yet ... ... Hopefully later this afternoon or tomorrow I'll get to it and get it running, had intended on working on it by now today but something else came up & I have to put it off for a while longer.
