Alongside the good news of 8-core Haswell-E parts, VR-Zone revealed an updated Intel road map that makes no mention of the 14nm Haswell architecture die shrink Broadwell. Broadwell was originally intended to be the next "tick" in Intel's yearly "tick-tock" chip release schedule set to release next year. If recent reports are true, this will no longer be the case. Instead, 2014 will be dominated (at least on the Intel side of things) by consumer Haswell and enthusiast-grade Haswell-E chips.
What is going on with Broadwell?
Broadwell is essentially supposed to be a CPU using the Haswell micro-architecture that is built on a (impressively) smaller 14nm manufacturing process. There may be a few minor tweaks to the architecture or updates to the instruction set extensions, but the big difference between Broadwell and Haswell is the die shrink from 22nm to 14nm. The die shrink will allow for better low-power performance and will be beneficial in battery-powered mobile devices first and foremost. Likely as a result of the main benefits being mobile parts, Intel has previously announced that Broadwell chips would be BGA only, which means that there would not be a traditional LGA socket-ed desktop part. Broadwell chips would only come soldered onto motherboards in bare-bones systems, laptops, and tablets for example.
Despite the small architectural differences, the die shrink alone is a monumental task. Intel needs to not only be able to shrink Haswell and its wealth of transistors to 14nm, but it has to do so in a way that allows them to get the yields and power efficiency characteristics that they want. This is extremely hard, and the move to manufacturing nodes below 22nm is going to get exceedingly difficult. Intel accomplished 22nm with its Tri-gate 3D transistors, but with 14nm they are going to have to push beyond that, and even with its huge money vault, physics is working against them in a big way here. As a result of the huge challenges of moving to 14nm, it seems at this point that Broadwell will not be ready in time for a 2014 launch after all. Instead, Intel is now shooting for a 2015 launch of the BGA Broadwell chips alongside the LGA (socket-ed) 14nm Sky Lake processors (the "tock" to Broadwell's "tick").
Some enthusiasts and media have painted the Broadwell delay to be, at least in part, due to less competition from AMD. That is possible, but I can't help but thinking that slowing down Broadwell is the last thing Intel would want to do. The sooner Intel is able to move its Haswell (and future) micro-architecture-based chips to 14nm and beyond, the sooner AMD is put all that much farther behind. If Intel had managed 14nm Broadwell in 2014, AMD would have been screwed out of a lot of SFF NUC-type systems as well as mobile devices as they would not really be able to compete on performance or power efficiency! (Then Intel could happily focus on trying to bring down ARM in the mobile space, which it seems to want to do heh.) In some internal discussion with PC Perspective's Josh Walrath, I think that Intel would have loved to bring 14nm chips next year but, because of manufacturing process woes, the chips are simply not ready.
The new plan: Refresh Haswell in 2014 with a new Z97 chipset
Now, with the launch of Broadwell moved back to at least 2015, consumers will now be presented with a refresh of 22nm Haswell chips on the consumer side around Q2 2014 and the upcoming launch of enthusiast-platform Haswell-E processors in the second half of 2014.
The Haswell (LGA 1150) refresh will include better binned chips with a lineup that is likely to see a slight speed bump in stock clockspeed across the board as well as an updated Z97 chipset. The new chipset will support 1000 MB/s SATA Express and boot-level malware protection technology in the form of Intel Device Protection and Boot Guard. Granted motherboards using the updated Z97 chipset are not going to be all that alluring to those users already running Z87 chipsets with their Haswell processors. However, users that have not yet upgraded might as well go with the newer chipset and enjoy the small tweaks and benefits that go along with it. In other words, if you were holding out waiting to upgrade to a Broadwell CPU plus motherboard combo, you are going to be waiting at least another year. You will be able to grab a refreshed Haswell CPU and a Z87 or Z97 chipset-based motherboard next year though (which should still be a healthy upgrade if you have a pre-Sandy Bridge system).
Also worth noting is that if you have already upgraded to Haswell, you can rest easy knowing that you have at least another year of your chip being the newest model--quite a feat considering how fast the tech world traditionally moves!
On the other hand, if Haswell just isn't fast enough, there is always Haswell-E to look forward to in 2014! Haswell-E will bring 8-core, 16-thread chips with 20MB of L3 cache (up to ~140W TDP) and the X99 chipset, which should keep the top-end enthusiast market happy no matter the state of Broadwell.
I'm looking forward to more details regarding the 14nm manufacturing process, and hoping that once the chips are on the way the company will be willing to talk about some of the challenges and issues they faced moving to such a small process node (perhaps at IDF? One can hope.) In the mean time, Haswell has another year to shine and make Intel money while AMD works on its HSA and APU strategies.
What do you think about the 14nm Broadwell delay? Does it impact you, or were you waiting for Haswell-E anyway?
Apple has seen a healthy boost in computer sales and adoption since the transition to Intel-based platforms in 2006, but the MacBook line has far and away been the biggest benefactor. Apple has come a long way both from an engineering standpoint and consumer satisfaction point since the long retired iBook and PowerBook lines. This is especially evident when you look at their current product lineup, and products like the 11” MacBook Air.
Even though it may not be the most popular opinion around here, I have been a Mac user since 2005 with the original Mac Mini, and I have used a MacBook as my primary computer since 2008. I switched to the 11” MacBook Air when it came out in 2011, and experienced the growing pains of using a low power platform as my main computer.
While I still have a desktop for the occasional video that I edit at home, or game I manage to find time to play, the majority of my day involves being portable. Both in class and at the office, and I quickly grew to appreciate the 11” form factor, as well as the portability it offers. However, I was quite dissatisfied with the performance and battery life that my ageing ultraportable offered. Desperate for improvements, I decided to see what two generations worth of Intel engineering afforded, and picked up the new Haswell-based 11” MacBook Air.
Since the redesign of the MacBook Air in 2010, the overall look and feel has stayed virtually the same. While the Mini DisplayPort connector on the side became a Thunderbolt connector in 2011, things are still pretty much the same.
In this way, the 2013 MacBook Air should provide no surprises. The one visual difference I can notice involves upgrading the microphone on the left side to a stereo array, causing there to be two grilles this time, instead of one. However, the faults I found in the past with the MacBook Air have nothing to do with the aesthetics or build quality of the device, so I am not too disappointed by the design stagnation.
From an industrial design perspective, everything about this notebook feels familiar to me, which is a positive. I still believe that Apple’s trackpad implementation is the best I've used, and the backlit chiclet keyboard they have been using for years is a good compromise between thickness and key travel.

Giada Technology has launched a new small form factor desktop PC with its upcoming D2308. The successor to the Giada D2305, the D2308 is a tiny PC that can be used for a variety of workloads. The mini PC, with up to a 70W system TDP, features an Intel "Haswell" processor and a discrete NVIDIA GPU (most likely mobile parts), which makes it a fairly powerful machine for the size!
The D2308 is enclosed in a black chassis with curved edges. Three Wi-Fi antennas stick up from the back of the PC. It looks rather like a home router or the mintBox PC, actually.
Internally, the Giada D2308 uses an Intel Core-i5 or Core i7 Fourth Generation Core CPU, a NVIDIA GTX 650 GPU with 1GB of video memory, up to 16GB DDR3 memory (in two SODIMM slots), a Realtek ALC662 5.1 HD audio codec, TPM module support, and two mini-PCI-E connectors for things like wireless cards or storage drives. The SFF PC can also accommodate a single 2.5" mechanical hard drive or SSD.
According to eTeknix, external IO includes two USB 2.0 ports, three USB 3.0 ports, a SD card reader, two HDMI video outputs, a Gigabit Ethernet port, and analog audio outputs. Pricing and availability have not yet been announced.
I have reached out to Giada for more information on the small form factor PC, but did not hear back from them in time for publication. I will update this post if the company responds to our questions. Although the D2308 is not a fan-less PC, it appears to have good hardware and would do well at a variety of HTPC, desktop, or office PC tasks.
Update: A Giada PC representative responded to our request for more information to let us know that the SFF PC uses the fourth generation Core i5/i7 processors and HM87 chipset along with NVIDIA GTX 650 graphics. It should be available towards the end of July.

Tagged: haswell, Intel, Second Opinion
Ryan reviewed the Core i7 4770K earlier in the month and found it an impressive product. He was not able to properly test the CPU paired with a discrete GPU because of time restraints; we value results measured from direct monitor output, which takes longer than FRAPS and other software results. Still, Ryan believes that the boost in raw CPU performance justifies its existence in desktops without a funky "-E" tagged along for good luck.
For a second opinion, you could check NitroWare to see what a cynical Aussie thinks of Intel's latest offering. Of note, they compare software-measured frame rates between the on-chip GPU and those measured from a GTX 460 on Sandy Bridge, Ivy Bridge, and Haswell. He is nothing if not thorough, collecting his findings over 20 pages.
Ultimately he finds that if you are running Ivy Bridge, you will not benefit too much from the upgrade; Sandy Bridge users and earlier, on the other hand, might want to consider this platform... unless they are wanting to jump into the enthusiast-slot offerings coming up late this year and Haswell-E late the following year.
Also be sure to check back when we have our frametime measurements complete!

In my analysis of the recent Intel Computex keynote, I noted that the displayed confidence came across more as repressing self-doubt. It did not seem, to me, like Intel wants to abandon the high-end enthusiast but rather catch up with their low performance and high efficiency competitors; they just know they are secure in that market. Of course, we could see mid-range choices dwindle and prices stagnate, but I cast doubt that Intel wants to exit the enthusiast market despite their silence about Ivy Bridge-E.
All Images, Credit: VR-Zone
And Intel, now, wants to return some confidence to their high-end consumers comma they are not slowing down exclamation point exclamation point.
VR-Zone, the site which published Ivy Bridge-E's lazy release roadmap, are also the ones to suggest Haswell-E will come before mainstream Broadwell offerings. Once again, all is right with the world. Slated for release around holiday 2014, just a year after Ivy Bridge-E, Haswell-E will come alongside the X99 chipset. Instead of Broadwell, the back to school window of 2014 will by filled by a refresh of 22nm Haswell products with a new 9-series chipset.
Seriously, it's like watching the face of Intel's Tick-Tock while a repairman is tweaking the gears.
In terms of specifications, Haswell-E will come in 8 and 6-core offerings with up to 20MB of cache. Apart from the inclusion of DDR4 support, the main advantage of Haswell-E over the upcoming Ivy Bridge-E is supposed to be raw performance; VR-Zone estimates up to 33-50% better computational strength. A depressingly novel area of improvement as of recent...
Lastly, with recent discussion of the awkwardly hobbled K-series parts, our readers might be happy to know that all Haswell-E parts will be unlocked to overclocking. This, again, leads me to believe that Intel is not hoping to suffocate the enthusiast market but rather sort their users: mid-range consumers will take what they are given and, if they object, send them on the bus to Funk-E town.
Note, while the headlining slide definitively says "All Processors Unlocked"...
... this slide says "For K and Extreme series products." I will assume the latter is out of date?
Which begs the question: what does our readers think about that potential strategy? It could lead to mainstream performance products being pushed down into BGA-territory, but cements the existence of an enthusiast platform.
Intel Prevents Overclocking of non-K Haswell Processors, and Strips Virtualization and TSX Features From K Parts

First revealed at IDF Beijing, Intel's latest generation 4th Generation Core "Haswell" processors enjoy a refined architecture, improved processor graphics, an integrated voltage regulator (FIVR), and for the enthusiast crowd, new methods for overclocking.
In truth, the methods for overclocking Haswell are very similar to those used to overclock Intel's Sandy Bridge and Ivy Bridge processors. However, Intel has further unlocked the new Haswell CPUs. Enthusiasts can set an overclocked Turbo clockspeed, use additional base clock (BCLK) values (100 MHz, 125 MHz, and 167 MHz), and overclock the unlocked processor graphics core clockspeed and memory clockspeed (memory in 200 MHz or 266 MHz steps). The additional BCLK values allow for easy overclocks without putting the other subsystems (such as the PCI-E bus, GPU, and memory) out of spec, which is important for the PCI-E bus which needs to be close to 100 MHz for a stable system.
The following PC Perspective articles have further information on overclocking unlocked "K" edition Haswell processors:
- Integrated Voltage Regulator and Overclocking Haswell - Ryan pushes a Core i7-4770K to 4.6GHz
- Intel Talks Haswell Overclocking at IDF Beijing - Intel outlines overclocking features of Haswell at IDF
Although Intel's overclocking reveal at IDF was fairly detailed, the company did not get into specifics on how overclocking would work on non-K chips.
On that note, the crew over at the Tech Report uncovered some rather disheartening facts such that the non-K edition Haswell processors will, essentially, be locked at stock speeds and not overclockable (they are slightly more locked down than previous generations).
While the K edition Haswell processors, such as the Core i7-4770K, will enjoy unlocked multipliers, unlocked GPU and memory clockspeeds, and additional BCLK options, the standard non-K chips (ie Core i7-4770, Core i5-4670, et al) will have locked multipliers, no Turbo Boost clockspeed overclocking, and will not be allowed to use the additional 125 MHz and 167 MHz BLCK options, which effectively makes overclocking these standard chips impossible. It may still be possible to push the BLCK up a few MHz, but without the extra
stepping and gearing ratio options, the other component clockspeeds based off that same base clock are going to go out of spec and will become unstable fairly quickly as you try to push that BLCK up.
There is one saving grace for enthusiasts considering a non-K part, however. The standard non-K CPUs will have Intel's latest TSX extensions and enterprise virtualization technologies enabled.
Although quite the head scratcher, Intel has decided to disable TSX, vPro, and VT-d on the unlocked K edition chips. The TSX extensions are not widely used yet, but will provide a noticeable performance boost to future programs that do take advantage of them by allowing developers to essentially mark off sections of code that can be run independently, and thus increase the multi-threaded-ness of the application by running as much code in parallel across multiple cores as possible. Further, the vPro and VT-d features are used by virtual machine applications (with VT-d being more relevant to the consumer side of things).
In short, Intel has continued to lock down and artificially limit its chips, as many enthusiasts suspected would happen. Standard non-K Haswell processors are more locked down than ever, and even the premium unlocked K CPUs suffer with the (odd) removal of TSX and virtualization support. As Mr. Gasior points out, enthusiasts are going to be faced with an odd choice where they can either spend extra money on a premium K part that will overclock but is limited in other ways, or go with the lower cost part that has all of the ISA extensions and virtualization support turned on... but is not overclockable.
In my opinion, locking down the standard chips is one thing-- Intel needs to incentivize enthusiasts to go with the more expensive (~$25 premium) unlocked K processors some how -- but if those same enthusiasts are spending extra money for a premium chip, they should get all the features the accompanying non-K SKU has as well as overclocking.
What do you think about the artificial limitations placed on the various Haswell SKUs?

Intel had a host of new technologies to show off at Computex this year, starting of course with the Haswell processor launch. Hopefully you have read our review of the Core i7-4770K LGA1150 CPU already but thanks to some video sent our way, we have other interesting bits to share.
Below you will see Intel demonstrating four new products. First is the Acer Aspire S7 using a Haswell dual-core platform playing back 4K content. Next up is an Ivy Bridge tablet that is running completely fanless (passive) thus generating no noise at all while still offering impressive CPU and graphics performance. Intel then pulls a Lenovo K900 Android smartphone out of its pocket powered by the Clovertrail+ enabled Atom Z2580 SoC. Finally, we get a sneak peak at the next-generation of SoC designs with a look at a Silvermont-based Baytrail tablet running at 2560x1440.
JJ pays PC Perspective a visit!
In case you hadn't heard, on June the 4th, (world famous) JJ Guerrero from ASUS stopped by the PC Perspective offices to help host a live stream focused on Z87 platforms and the Intel Haswell processor. Since Intel decided to launch on a Saturday morning, you might have missed the boat: the Core i7-4770K was reviewed right here on PC Perspective and the results are pretty good.
Motherboards, we got motherboards here!!
Along with Haswell though is the release of the new Z87 chipset and with THAT, about 100 different ASUS motherboards. I exaggerate, but only a little. In our live stream that aired for about 4.5 hours, JJ and I discussed about 20 different motherboard ranging from Mini-ITX options to the budget-minded Z87-A and even the ROG Maximus VI Extreme!
Below you will find an on-demand version of the stream, broken up into five segments.
ASUS Z87 Motherboard Segmentation
This first segment details the mindset ASUS had when creating the four different motherboard product lines: Mainstream, Workstation, TUF and ROG. Why do they need all of these options and what features and quality points are common across the entire families?
ASUS Mainstream Z87 Motherboard Lineup
ASUS' new mainstream line of motherboards with the z87 chipset range from the Z87-A to the Z87-Deluxe/Dual. JJ talks about the features that are added as you move up the product stack so that you can find the option that fits your platform needs and budget.
An new era for computing? Or, just a bit of catching up?
Early Tuesday, at 2am for viewers in eastern North America, Intel performed their Computex 2013 keynote to officially kick off Haswell. Unlike ASUS from the night prior, Intel did not announce a barrage of new products; the purpose is to promote future technologies and the new products of their OEM and ODM partners. In all, there was a pretty wide variety of discussed topics.
Intel carried on with the computational era analogy: the 80's was dominated by mainframes; the 90's were predominantly client-server; and the 2000's brought the internet to the forefront. While true, they did not explicitly mention how each era never actually died but rather just bled through: we still use mainframes, especially with cloud infrastructure; we still use client-server; and just about no-one would argue that the internet has been displaced, despite its struggle against semi-native apps.
Intel believes that we are currently in the two-in-one era, which they probably mean "multiple-in-one" due to devices such as the ASUS Transformer Book Trio. They created a tagline, almost a mantra, illustrating their vision:
"It's a laptop when you need it; it's a tablet when you want it."
But before elaborating, they wanted to discuss their position in the mobile market. They believe they are becoming a major player in the mobile market with key design wins and outperforming some incumbent system on a chips (SoCs). The upcoming Silvermont architecture pines to be fill in the gaps below Haswell, driving smartphones and tablets and stretching upward to include entry-level notebooks and all-in-one PCs. The architecture promises to scale between offering three-fold more performance than its past generation, or a fifth of the power for equivalent performance.
Ryan discussed Silvermont last month, be sure to give his thoughts a browse for more depth.

Tagged: Kabini, Intel, haswell, gigabyte, computex 2013, computex, brix, amd
Earlier this year, Gigabyte showed off a new small form factor (SFF) mini PC called the Brix during its New Idea Tech Tour. Those initial models came equipped with Intel Ivy Bridge processors, two SO-DIMM slots (a maximum of 16GB of DDR3 1600MHz memory), one mSATA slot, and one mPCI-E connector for storage and wireless networking respectively. The Brix hardware is housed in an aluminum chassis that doubles as a heatsink. However, since the Brix's debut, both Intel and AMD have come out with new more power efficient processors. In light of this, Gigabyte is not only showing off the original Brix PC at Computex 2013, but a new SKU called the GB-XM1 that comes equipped with your choice of Intel Haswell or AMD Kabini processors.
The new 4.5 x 4.2 x 1.2" Gigabyte Brix XM1 PC supports mSATA, mPCI-E, dual display outputs, USB 3.0, and is VESA mountable. The Haswell variant's processor options range from a Core i3-4010U to a Core i7-4500U. On the AMD side of things, the GB-XM1 is available with options ranging from the E1-2100 to the A4-5000. All of the AMD "Kabini" chips are outfitted with 12 Radeon cores, but they differ from there. The highest-end chip, the A4-5000, is a quad core with 2MB of L2 cache while the lower tier chips are dual cores with only 1MB of L2 cache. The following chart outlines all of the Haswell and Kabini CPU choices.
|GB-XM1 (Haswell)||GB-XM1 (Kabini)|
For more information on Kabini, check out our review of the AMD A4-5000 Kabini processor. If you need a refresher on Intel's Haswell architecture, you can also find a review of the Core i7-4770K here.
Gigabyte has not released pricing or availability information on the GB-XM1, but expect the Kabini models to be noticeably cheaper than the Haswell counterparts. Thankfully, it is not all bad news for Kabini users, as the Radeon cores help the low power processor accomplish 3D and media playback tasks, as noted in Josh's review.
For those interested in the mini Brix PC as a media center box or low-power desktop PC, Engadget reports that Gigabyte is also experimenting with specialized Brix SKUs, including a wireless charging pad for mobile devices and another Brix with a Pico projector. These accessories are merely prototypes at this point and may not go into mass production.
I'm glad to see Gigabyte moving forward with its Brix lineup to provide a useful alternative to Intel's NUC.
