Apple MacBook Air 13 with Thunderbolt

The 2011 MacBook Air addresses nearly every concern anyone could lob at its predecessor. It's still light on ports, the missing SD slot on the 11-inch model is a drag, and no, it isn't cheap, but this machine is fast, efficient, and not to be underestimated. It's a supermodel with a law degree from Columbia, a hunky motorcycle racer who looks good in leathers yet is also a concert pianist -- whatever your passion it won't disappoint, all while making a lot more room in your bag. More room for what? Well, your life, for starters.

When last we tested an Air, the 13-inch model with a 1.83GHz Core 2 Duo processor scored a 2,717 on the GeekBench benchmark. This new 13, configured with the default 1.7GHz Core i5 and paired with 4GB of DDR3 and a 128GB SSD, nearly doubled that: 5,373. No, that won't threaten the full-bore 15-inch MacBook Pro for sheer speed, but double the performance in nine months is a welcome improvement, living up to Apple's 2x promises here, and from what we've seen elsewhere the 11-inch lives up to its 2.5x promises as well.

The outside of this 2011 refresh of the MacBook Air is virtually indistinguishable from that which came before it. Yes, that means compromises. On the 13-inch model you'll still have to make do with but one USB port on the left and one on the right, but now that latter one is flanked by a Thunderbolt connector, Apple's implementation of Intel's Light Peak standard. This 10Gb/sec interconnect has become standard fare on all new machines coming out of Cupertino, a fact that should help to accelerate the so-far tardy uptake in support from accessory manufacturers.

The 11-inch model is likewise emblazoned, but sadly has still not been granted an SD reader, something restricted to the bigger 13. On the left you'll find a 3.5mm headphone jack, the MagSafe power connector and... nothing else. All other ports have been deemed unnecessary by Apple's designers and therefore relegated to myriad USB adapters for things like Ethernet -- though if you start relying on those you'll likely need to start packing a USB hub as well.

Like before, the omission of these ports leaves the Air free to pinch down to a delicious taper beneath the keyboard, thin enough to make for a decent cleaver when no proper blade can be found -- or when you just can't be bothered to find one. Even on the fat end it measures a mere .68-inches (17mm) thick. Or thin, rather. (engadget.com)

Intel's Core i7-980X Launches with a Bang

Intel today launches its newest processor, the Intel Core i7-980X Extreme Edition, which promises to be the new king of the CPU hill. The Core i7-980X Extreme Edition (codenamed "Gulftown") is Intel's first six-core processor for consumers, more specifically gamers and well-heeled multimedia professionals.
The Core i7-980X replaces the Core i7-975 as the top-of-the-line Intel processor. It costs approximately $999 per chip, which is the same price as the i7-975. (It's therefore no surprise that the Core i7-975 will be going away soon.) The Core i7-980 is truly a "drop-in" replacement, since it shares the same LGA-1366 socket as the i7-975 (and i7-920, i7-960, etc.). You should be able to use the most recent motherboards with an Intel X58 Express chipset; all you'll have to do is flash the motherboard's firmware before you install the chip. The usual suspects will have BIOS updates available on their Websites: Intel, ASUS, Gigabyte, MSI, Foxconn, EVGA, Biostar, etc.

The Core i7-980X has six cores and comes with Intel's Hyper-threading technology. This means it can work on twelve streams at once. This is a boon for people that need multi-processing, like graphics professionals transcoding videos, or people doing 3D rendering in software (think CGI). Like previous Core i7 systems, the i7-980X has TurboBoost, which can turn off some of the cores and give that power to the remaining cores (if, for example, your photo editing program can only address two cores). It also can "boost" all six cores above the usual 3.33-GHz specs, as long as the CPU cooler can keep up with the heat output. Intel can do this because it builds a large amount of overhead into its chip design, so that its new standard cooling fan can handle the occasional spike in thermal energy. Needless to say, this on-demand overclocking won't be constant, but most of the time a computer is waiting for you, rather than vice versa.

Another boost in performance is the result of the larger 12MB L3 cache on the processor (up from 8MB on the Core i7-975). The L3 cache is a holding cell for the data the CPU is processing, and more L3 cache means that the CPU has to access the relatively slower DDR3 memory less often. The cache will help speed up single-threaded tasks like gaming, though as seen in our testing, the choice of GPU is still more important to the hardcore gamer..

Not surprisingly, the Core i7-980X will show up on gaming PCs first, like the Maingear Shift and Falcon Northwest Mach V (Core i-980X). Well-heeled gamers are exactly the type of consumer who will crave a $6,000+ system with a $1,000 processor and $1,500 worth of graphics cards. Gaming system builders have a lot of experience combining the extra overhead in the CPU's thermal envelope with liquid cooling to bump the stock 3.33GHz clock speed up to as much as 4.3GHz while running heavy loads. The overclocked processors still cool down while idle, so they're not running at full speed all the time.

So, is it worth it? Yes and no. Our performance tests with the Falcon Northwest Mach V and Maingear Shift show a significant performance bump in multi-threaded tasks like CineBench R10 (a doubling of performance from the mid-range Core i7-870). There's also a significant speed bump for the PCMark Vantage test, which is multi-threaded and measures day-to-day tasks. However gaming tests still depend more on the graphics you put into the system, with the credit going to multi-GPU systems rather than multi-core CPUs. The multimedia tests are starting to reach a plateau of diminishing returns: while the scores are still getting faster, having an ultra-fast quad core and SSDs are "enough" for tasks like Windows Media Encoder and PhotoShop CS4. Throwing two more cores at the multimedia tasks won't help at this time. Maybe they will help when Adobe releases CS5; time will tell. (story Link)

Intel Core i7 [860] Lynnfield Processor Review

Last week Intel's latest addition to its arsenal of desktop processors was released in the form of the Core i7 and Core i5 series' for the LGA1156 socket. These new cores, previously known as Lynnfield (and we will still call it as much throughout our reviews), differ from the previously available Bloomfield processors (only available as Core i7 CPUs for the LGA1366 socket) in a few ways:

• Dual-channel memory controller- Lynnfield does indeed still have an integrated DDR3 memory controller but here Intel has removed one of the channels from Nehalem to make the new core dual-channel. While this is theoretically a performance drawback, in real-world testing (as you will soon see) the third channel made very little performance difference in most consumer applications. By removing one channel Intel was able to make the CPU package smaller (less pins required), lower the cost of ownership (only two DIMMs needed now) while keeping performance very high.
• No QPI interface- While Nehalem used the QPI interface to communication with the north bridge of the motherboard, Lynnfield uses a connection called DMI. DMI is much slower than QPI (2 GB/s versus 26 GB/s or so) but in nearly all cases that bandwidth will be more than adequate for the amount of data moving between the processor and chipset even in a worst case scenario. Again, with this change, Intel was able to lower the pin count for Lynnfield in relation to Nehalem.
• Integrated PCI Express 2.0- A first for a consumer processor, Lynnfield actually takes 16 lanes of PCIe 2.0 and moves them onto the die of the processor itself. That means that the graphics cards (or any other PCIe devices) now communicate directly with the processor itself rather than through a north bridge or chipset controller. The advantage here is for a lower cost chipset though I am betting that performance advantages from this are going to be minimal to non-existent. This is basically another move towards a more highly integrated platform on the Intel CPU.
• Split HyperThreading integration- HyperThreading is still around on the Lynnfield processors, but it will only be enabled on SOME of the product offerings. While the die size and transistor counts will be exactly the same, Intel will basically just flip off the HyperThreading capability in order to create a market differentiation and pricing segmentation. More details on what CPUs have what on the next page.
• Larger Turbo Mode differentiations- While Lynnfield was being prepared Intel's engineers found out how to get a little more frequency out of the Nehalem architecture and you'll notice that when you see the larger Turbo Mode improvements on Lynnfield. Essentially, the cores have been fine tuned in a way that will allow them to auto-overclock higher than even the most expensive Core i7 processors available today.

I won't get into all of the architectural or product differences here, but if you are still a bit behind the curve in that regard you should definitely be checking out the previous Lynnfield launch review in which I go into great detail about all things new and old in the processor, motherboard chipset options, pricing and more.

While we already tested the Core i7-870 and Core i5-750 processors, the Core i7-860 finds itself resting directly in the middle of those two parts in terms of clock speeds and Turbo Mode overclocking. (full Story)

Intel May Release Core i7 975

Several distributors and retailers are showing that Intel's upcoming Core i7 975 will ship at the beginning of April, not the end of May.
Is the Intel Core i7 975 coming sooner than we think? That's what many distributors and retailers are reporting, and actually have the upcoming processor listed for next month. As an example, this website shows an April 6 street date, and this website shows an estimated date of April 7. Granted, these dates aren't official, and are estimates only. However, it's a huge jump considering that the Core i7 975 wasn't expected to ship until the end of May.
The release of the 45nm Core i7 975 (Extreme) is a rather highly-anticipated one, as the quad-core Bloomfield processor will serve as the new flagship chip for Intel, boasting a core speed of 3.33 GHz, support for LGA 1366 sockets, uses 1 MB of L2 cache and 8 MB of L3 shared cache memory, and has a TDP of 130W. Recently the processor was leaked, overclocked, and benchmarked, pushed up to an "extreme" clock core speed of 5,239 MHz, breaking the then-current record of Futuremark's 2DMark05 benchmark application. As it stands now, the benchmarked rig featuring the Core i7 975 sits in the #2 position, recently conquered by a rig sporting Intel's Core i7 965.
As of this writing, the Intel Core i7 975 will cost end-users a whopping $999 USD; the Core i7 950, clocking in at 3.06 GHz, will be available as well for a cheaper-but-still-hefty $562 USD. Other processors included in the original May lineup consist of the Core 2 Duo E7600 ($84), the Pentium Dual-Core E6300 ($84), and the Celeron Dual-Core E1600 ($53).
Intel also plans to ship six Core 2 Quad processors next month. (link)
