AMD's 12-core "Magny-Cours" Opteron 6174 vs. Intel's 6-core Xeon

This one may be a bit too subtle for most, but bear with me here.  AMD's latest Opteron has a lot of cores, 12 per chip to be exact.  It's got so many cores that AMD's codename for the chip is Magny-Cours.  Did I mention that AMD likes naming things after Formula 1 courses?  Gotta get the most out of that Ferrari sponsorship. The target?  Intel's new 32nm 6-core Xeon processors, introduced just two weeks ago. AMD is roughly a year away from shipping 32nm CPUs in volume, and the same distance away from its brand new Bulldozer architecture, so AMD had to do something more drastic to compete. AMD sent us a test platform with a pair of 12-core Opteron 6174s.  We're talking about a 692mm2 die, 19.6MB of cache and 12 Opteron cores on a single package.  And we've got two of them.  Is that enough to beat Intel's 6-core Xeons?  Let's find out. <a target="_blank" href="http://www.anandtech.com/show/2978/amd-s-12-core-magny-cours-opteron-6174-vs-intel-s-6-core-xeon">Read more...</a>

The Core i7 980X Review: Intel's First 6-Core CPU

11 March 2010, 22:49

Written by Foxter

Rating: 0 (Rates: 0)

It’s rare that anything we review has the longevity that Intel’s Core i7 Bloomfield platform has enjoyed. If you were one of the fortunate few to buy a Core i7 920, 940 or 965 back in November 2008, you’d still have one of the fastest desktop CPUs today in March 2010. In fact, other than a few minor speed bumps, Intel hasn’t done much with its LGA-1366 platform in the past 15 months. Last year Intel introduced Nehalem for the rest of us with its LGA-1156 socket and in January we got the first dual-core derivatives.  Now it’s finally time to take care of the folks who invested in Nehalem and Core i7 early on. In the coming weeks Intel will be shipping its first 6-core desktop processor, built using the same 32nm process used in the Clarkdale Core i3/i5 CPUs. It’s codenamed Gulftown but today we can call it the Core i7 980X. Did I mention that with a BIOS update it’s fully compatible with all X58 motherboards? That’s right, even if you bought a board in November 2008 - you can upgrade directly to Gulftown. <a target="_blank" href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3763">Read more...</a>

Intel Core 2 CULV Roundup: Who Needs Atom ?

04 February 2010, 22:22

Written by Foxter

Rating: 0 (Rates: 0)

A couple years back, ASUS released the first netbook on an unsuspecting world. Compared to the UMPCs and other tiny handhelds that preceded it, the Eee PC offered more in some areas and cost a lot less - and compared to ultraportables, it was smaller and cost about one fifth as much! Many consumers fell in love with the netbook, and now every major laptop company has some form of netbook. Intel just released the Pine Trail platform that updates Atom in a few areas, but Pine Trail is less about improving performance and more about reducing costs - mostly Intel's costs, as the new netbooks all cost the same or slightly more than preceding models. So yes, Atom is undoubtedly a success, but are Atom-based netbooks truly good are they just a current fad? To answer that question, we need to look at the next step up the mobile ladder: Intel's CULV platform. CULV (Consumer Ultra Low Voltage) processors have been around for a while, but where formerly they were the domain of $1500+ ultraportables, netbooks have forced them into much lower price brackets. If the choice is between a $330 Pine Trail unit and a $1500 CULV, few would opt for the latter; today, the difference is a lot less, with some CULV designs starting as low as $400. It's no surprise that the least expensive models are more difficult to find in stock, and we're left to wonder if the problem is inadequate production or if the manufacturers are intentionally producing low volumes with the hope of getting more users to spring for higher cost offerings. Realistically, you're far more likely to find CULV laptops priced around $600, but a quick search turns up quite a few priced under $450 (though admittedly many vendors are backordered). Even at twice the cost of a netbook you should give them serious consideration, and in this roundup we'll show you why. <a target="_blank" href="http://www.anandtech.com/mobile/showdoc.aspx?i=3735">Read more...</a>

AMD is looking a lot more competitive in 2010 than I expected just a few months ago. Intel finally unveiled Clarkdale and thanks to the high cost of Core i5 ownership AMD hasn't really been threatened. The Core i3 530 is the biggest threat, but it only competes with one member of AMD's lineup at $113. Thanks to continued improvements in Global Foundries' 45nm process, AMD is delivering slight clock bumps for its dual, triple and quad-core processors while dropping prices of others. <a target="_blank" href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3726">Read more...</a>

The Intel Core i3 530 Review - Great for Overclockers & Gamers

23 January 2010, 14:10

Written by Foxter

Rating: 0 (Rates: 0)

It’s about time we got an interesting value processor to review from Intel. I simulated one in our Clarkdale review, but today I’m bringing you a full review of the most interesting dual-core Westmere for the desktop - the Core i3 530.  Priced at $113 (and selling for about $125 on the street) the 530 runs at 2.93GHz and features no turbo modes. It’ll run at 1.33GHz at its lowest frequency, and no faster than 2.93GHz at full load. The missing turbo boost is almost all you sacrifice as the 530 still has a hefty 4MB L3 cache shared between both cores. Each core gets a 256KB 10-cycle L2, just like the i5s and i7s. In a market full of good alternatives, whether it’s an ultra-cheap quad-core or a solid dual-core, it’s time to find out if there’s any value in the Core i3 530. <a target="_blank" href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3724">Read more...</a>

Today Intel is expanding their LGA1156 platform processor lineup by rolling out new dual-core Clarkdale processors manufactured with 32 nm process. The manufacturer has every intention to make them a true sales hit: they will exist in three different families and the prices of different models will lie in the interval between $84 and $284. What are the real marketing prospects of these new solutions and has Nehalem microarchitecture retained all its charm in the dual-core incarnation. These are the questions we will try answering in our today’s article. <a href="http://www.xbitlabs.com/articles/cpu/display/clarkdale-review.html">Read more...</a>

Intel Arrandale: 32nm for Notebooks, Core i5 540M Reviewed

04 January 2010, 21:31

Written by Foxter

Rating: 0 (Rates: 0)

Clarkdale is the desktop processor, but Arrandale is strictly for my notebooks. The architecture is the same as Clarkdale. You've got a 32nm Westmere core and a 45nm chipset on the same package. The two-chip solution does matter more for notebooks as it means that motherboards can shrink. Previously this feature was only available to OEMs who went with NVIDIA's ION platform (or GeForce 9400M as it was once known). This is the first incarnation of Intel's 32nm process so it's not quite as power optimized as we'd like. The first mainstream Arrandale CPUs are 35W TDP, compared to the 25W TDP of most thin and light notebooks based on mobile Core 2. Granted the 35W includes the graphics, but it's not always going to be lower total power consumption (more on this later). The Arrandale lineup launching today is huge. Intel launched 7 Clarkdale CPUs, but we've got a 11 mobile Arrandale CPUs coming out today. The architecture is similar to Clarkdale. You get private 256KB L2s (one per core) and a unified L3 cache for the CPU. The L3 is only 3MB (like the Pentium G9650) on the Core i5 and Core i3 processors, but it's 4MB (like the desktop Core i5/i3) on the mobile Core i7. Confused yet? I'll have to admit, Intel somehow took a potentially simple naming scheme and made it unnecessarily complex. We also get some low-voltage parts that have 18W TDPs. They run at low default clock speeds but can turbo up pretty high.  Turbo is hugely important here. While Clarkdale's Turbo isn't exactly useful, the TDPs are low enough in mobile that you can really ramp up clock speed if you aren't limited by cooling. Presumably this will allow you to have ultra high performance plugged-in modes where your CPU (and fans) can ramp up as high as possible to get great performance out of your notebook. Add an SSD and the difference between a desktop and a notebook just got even smaller. Arrandale does have one trick that Clarkdale does not: graphics turbo.   GPU bound applications (e.g. games) can force the CPU part of Arrandale into a low power state, and the GPU can use the added thermal headroom to increase its clock speed. This is a mobile only feature but it's the start of what will ultimately be the answer to achieving a balanced system. Just gotta get those Larrabee cores on-die... Chipsets are even more complicated on the mobile side. <a href="http://www.anandtech.com/mobile/showdoc.aspx?i=3705">Read more... </a>

The Clarkdale Review: Intel's Core i5 661, i3 540 & i3 530

04 January 2010, 21:18

I swear this is the longest it’s taken for an Intel architecture to penetrate the market. We first met Nehalem on November 3rd, 2008. It came to us as a high end quad-core processor and took a full year to make it to more affordable motherboards in the form of Lynnfield. Even with P55 motherboard prices down at the magical $99 marker, Intel relinquished control of the $100 - $200 CPU market without a Nehalem to compete down there. Instead we were left with a choice between Penryn, the update to Intel’s 2006 Conroe architecture, or Phenom II, AMD’s low-cost Nehalem competitor. The choice was simple.  From $100 to $200, your best bet has been AMD. Either through aggressive pricing on quad-core CPUs or the L3-cache-less Athlon II line, AMD controls the $100 - $200 market. Today we meet Intel's first 32nm CPUs, codename Clarkdale, designed to specifically target that $100 - $200 market. Technically Clarkdale isn’t Nehalem, it’s Westmere. Take Nehalem, use 32nm transistors, add in some new instructions for accelerating encryption/decryption, and you’ve got the makings of Westmere.  Clarkdale uses a dual-core Westmere and sticks it next to a 45nm Intel GMA die. That’s right, meet the first (er, second) Intel CPU with on-chip graphics. Next year we’ll see Sandy Bridge bring the graphics on-die, but until then we have Intel’s tried and true multi-chip-package to tide us over. We don’t get on-die graphics yet because Intel still hasn’t switched over to its make-everything-at-the-best-process-ever strategy. The 32nm fabs are ramping up with CPU production and the 45nm fabs need something to do. Nearly every desktop and laptop sold in 2010 will need one of these 45nm GMA die, so the fabs indeed have something to do.  It’s not all rosy with Clarkdale unfortunately. Remember the memory controller that Nehalem so graciously integrated? Clarkdale kicks it off die again. The IMC is housed in the 45nm GMA die. It’s still on-package, but not on-die. The benefit is super fast memory access for the graphics core, but slower memory access for the CPU core. In fact, this is a derivative of the memory controller used in older Intel chipsets (e.g. P45/X48). The CPU connects to the GMA die using QPI, so bandwidth shouldn’t be as big of a problem. Latency is unfortunately hurt as a result. Access times can be longer than older LGA-775 processors thanks to this memory controller design being optimized for FSB architectures. Again, the problem goes away with Sandy Bridge, but today we’re faced with it.  Like Lynnfield, Clarkdale uses Intel’s LGA-1156 socket. Clarkdale should work in all P55 motherboards, but you’ll need a BIOS update. No existing P55 motherboards route video from the socket to a VGA/DVI/HDMI connector, so you’ll need a new motherboard if you want to take advantage of the on-package graphics. Enter the H55, H57 and Q57 chipsets. The H and Q-series of chipsets feature what Intel calls its Flexible Display Interface (FDI). This is basically a link between the CPU and the chipset that passes along video output. H5x/Q57 motherboards will have a video out on board so you can use Clarkdale’s integrated graphics. Support for Intel’s Rapid Storage Technology is probably the main reason you’ll want H57 over H55. The difference between H57 and Q57 boils down to security and management features. The H-series is for consumers, the Q-series is for corporate customers. Make sense?   <a href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3704">Read more...</a>

AMD Athlon 2650e & X2 3250e - Better than Atom for SFF Desktops

01 January 2010, 14:49

Written by Foxter

Dell has really come into its own in the past few years. Shedding the image (and fur?) of yet another cheap PC OEM, Dell has tried to make design a more important part of its manufacturing as of late. Not every design is a win, but the zino HD appears to be the first nettop styled to have mass market appeal. As soon as Dell announced the zino HD I was bombarded with emails. Not for a review of the system, but for a review of the processors inside the machine. The 2650e is a single-core K8 based Socket-AM2/AM2+ processor that runs at 1.6GHz. It’s got 512KB of L2 cache and the rest of the feature set of the older K8 AM2 processors. As an AM2 chip it’s DDR2 only and physically won’t fit or work in an AM3 motherboard. Keep that in mind before you go sticking one of these where it doesn’t belong. Based on its specs, the Athlon 2650e is a near perfect competitor for Intel’s Atom. The newly announced D510 runs at 1.66GHz (close enough), but is an in-order architecture with Hyper Threading. Bottom line? The Athlon 2650e should be faster in single threaded apps, but slower in multitasking/multithreaded applications. Great. Atom boasts a lower total TDP as well. The Athlon X2 3250e fixes the 2650e’s biggest shortcoming by adding a second core. The clock speed drops a bit to 1.5GHz, but the rest of the specs stay the same. TDP goes up from 15W on the 2650e to 22W for the 3250e.    <a href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3703">Read more...</a>

Intel Atom D510: Pine Trail Boosts Performance, Cuts Power

21 December 2009, 08:42

Written by Foxter

Rating: 0 (Rates: 0)

Intel announced the Atom processor in 2008. That same year we were introduced to the first two members of the family: Diamondville and Silverthorne. The chips were both called Atom, but they differed in their application. Diamondville was used in desktops, nettops and netbooks, while Silverthorne was almost exclusively for MIDs (Mobile Internet Devices).  Atom continues its split personality. Silverthorne begets Moorestown, the next-generation Atom for MIDs and smartphones. Diamondville on the other hand, leads us to Pine Trail: the next-generation Atom for desktops, nettops and netbooks. Pine Trail is the platform codename, Pineview is the codename for the new Atom CPU. Pineview takes the same 45nm Atom architecture introduced in 2008 and integrates a memory controller, DMI link and GMA 3150 graphics core. Integrating the memory controller is extremely important for Atom as it continues to be an in-order architecture. With minimal options for reordering instructions on the fly, if Atom encounters a load the pipeline stalls while the memory request completes. Despite Atom’s sensitivity to memory latency, most synthetic tests showed a minimal improvement in memory latency from Pineview. The real world performance benefit is also less than expected but tangible, but for whatever reason that’s not manifested in any synthetic memory latency tests. More on this shortly. <a href="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3692">Read more...</a>
