hardCOREware is engaging in a bit of informed speculation on how overclocking the upcoming Haswell chips will be accomplished. Now that Intel has relaxed the draconian lock down of frequencies and multipliers that they enforced for a few generations of chips, overclockers are once again getting excited about their new chips. They talk about the departure of the Front Side Bus and the four frequencies which overclockers have been using in modern generations and then share their research on why the inclusion of a GPU on the CPU might just make overclockers very happy.
"This is an overclocking preview of Intel’s upcoming Haswell platform. We have noticed that they have made an architectural change that may be a great benefit to overclockers. Check out our thoughts on the potential return of BCLK overclocking!"

PlayStation 4 (PS4) Orbis Hardware Specifications - AMD APU or Discrete?

Earlier today a report from Kotaku.com posted some details about the upcoming PlayStation console, code named Orbis and sometimes just called the PS4. Kotaku author Luke Plunkett got the information from a 90 page PDF that details the development kit so the information is likely pretty accurate if incomplete. It discusses a new controller and a completely new accounts system but I was mostly interested in the hardware details given.
We'll begin with the specs. And before we go any further, know that these are current specs for a PS4 development kit, not the final retail console itself. So while the general gist of the things you see here may be similar to what makes it into the actual commercial hardware, there's every chance some—if not all of it—changes, if only slightly.
This is key to keep in mind because here are the specs listed on the report:
- 8GB of system memory
- 2.2GB of graphics memory
- 4 module (8 core) AMD Bulldozer CPU
- AMD "R10xx" based GPU
- 4x USB 3.0 ports and 2x Ethernet connections
- Blu-ray drive
- 160GB HDD
- HDMI and optical audio output
We are essentially talking about an AMD FX-series processor with a Southern Islands based discrete card and I am nearly 100% sure that this will not match the configuration of the shipping system. Think about it - would a console developer really want to have a processor that can draw more than 100 watts inside its box in addition to a discrete GPU? I doubt it.
Instead, let's go with the idea that this developer kit is simply meant to emulate some final specifications. More than likely we are looking at an APU solution that combines Bulldozer or Steamroller cores along with GCN-based GPU SIMD arrays. The most likely candidate is Kaveri, a 28nm based product that meets both of those requirements. Josh recently discussed the future with Kaveri in a post during CES, worth checking out. AMD has told us several times that Kaveri should be able to hit the 1.0 TFLOPs level of performance and if we compare to the current discrete GPUs would enable graphics performance similar to that of an under-clocked Radeon HD 7770.
There is some room for doubt though - Kaveri isn't supposed to be out until "late Q4" though its possible that the PS4 will be the first customer. It is also possible that AMD is making a specific discrete GPU for implementation on the PS4 based on the GCN architecture that would be faster than the graphics performance expected on the Kaveri APU.
When speaking with our own Josh Walrath on this rumor, he tended to think that Sony and AMD would not use an APU but would rather combine a separate CPU and GPU on a single substrate, allowing for better yields than a combined APU part. In order to make up for the slower memory controller interface (on substrate is not as fast as on-die) AMD might again utilize backside cache, just like the one used on the Xbox 360 today. With process technology improvements its not unthinkable to see that jump to 30 or 40MB of cache.
With the debate of a 2013 or 2014 release still up in the air, there is plenty of time for this to change still but we will likely know for sure after our next trip to Taipei.
CES 2013: Haswell Ultrabooks Have New Requirements
Subject: General Tech, Processors, Mobile, Shows and Expos | January 7, 2013 - 05:05 PM | Scott Michaud

Oh certification, how I loathe thee.
At the Intel CES 2013 keynote, Intel announced a few new requirements for OEMs to manufacture Haswell-based ultrabooks. Intel clearly wants to push OEMs to utilize several of their more cherished features and as such they will not allow products to be released without these features.
Threat detected.
A fourth-generation ultrabook must contain the following features:
- Touch interaction support
- Intel WiDi support
- Installed Antivirus and Anti-Malware, Intel-owned McAfee will have an announcement soon.
These three certification requirements lead to two major points of contention with me: non-Windows 8 operating systems as well as Intel potentially strong-arming McAfee into your machine. When Intel requires touch support for Haswell-based ultrabooks, they basically declare that Windows 7 and Linux will not be around.
That requirement could seem minor depending on what Intel McAfee will soon announce after Intel’s announcement that Antivirus and Anti-Malware will be required on ultrabooks. Windows 8 already comes with Microsoft Security Essentials pre-installed and as such Intel might strong-arm vendors into using McAfee. It would not be a stretch to speculate that McAfee will have some deep attachment to the Haswell architecture. Unfortunately we will need to wait until Intel makes their announcement.
Intel also claims that ultrabooks will have touch-based products in the $599 price points very soon.

CES 2013: Vizio Creates Windows 8 Tablet with AMD CPU

Tagged: CES, ces 2013, vizio, amd
Why not open up CES-proper discussion with a tablet announcement?
AMD has begun their push into the tablet space with Vizio being one of their first OEM partners to announce products at CES. Due to AMD being one of the select few to still maintain a proper x86 license, they are about your only option outside of Intel for a true Windows 8 tablet. Vizio took them up on that position.
The Vizio Tablet PC, seemingly a play on their original Android-based Vizio tablet with an added declaration that “I am a PC”, will run standard Windows 8 certified as Microsoft Signature. No bloatware will be included which should help users experience the performance that 60-day antivirus trials and auto-launched demo notifications absorb.
On the technical side, the Tablet PC is loaded with 2 GB of RAM, an 11.6” full 1080p display, and a 1.0 GHz AMD Z60 processor. 64 GB of solid state storage is included although Windows 8 has been known to stake claims to a large portion of that. Readers of our site would probably have a primary computing device although this might be worth watching as a secondary device. You do not have a whole lot of other options for Flash support or access to non-default browsers.

Intel Leaks Valleyview and Bay Trail Slides
Subject: Processors | January 6, 2013 - 05:09 PM | Josh Walrath
Tagged: valleyview, low power, Intel, Bay Trail, atom
When the original Intel Atom hit the scene, it was a reasonably large success for Intel with the massive explosion of netbooks. The original design was very simplistic, but was fairly power efficient. The weak link of the original Atom was the 945 chipset graphics that were not only underpowered, but were based on a relatively power hungry desktop chipset. The eventual competition from AMD featured a next generation low power core based on the Bobcat architecture which featured a modern graphics core that was more than adequate for most scenarios.
Intel never stood still, but their advancement of the low power cores was slow as compared to the massive leaps and bounds we saw from the original Core architecture in 2006 on the desktop and server markets. Typically these products lagged the desktop products in terms of process nodes, but they continued to advance these cores little by little.
Leap forward a few years and we saw the eventual demise of the netbook and the massive uptake of mobile computing. Mobile computing was primarily comprised of tablets and smartphones. Intel was late to the party as compared to products from Qualcomm, Samsung, and NVIDIA. A fire was lit under the Atom group at Intel, as the competition had far surpassed the company in ultra-mobile parts.
Happily for those of us paying attention, the 3D Center Forum has released some very interesting slides about the 22 nm generation of Atom products and the platforms they will be integrated into. Valleyview is the SoC while Bay Trail is the platform.
Valleyview is based on Intel’s 22 nm process and will be a next generation Atom processor with a multitude of new features. It will be a SoC as it will no longer require a traditional southbridge. It will have improved graphics as compared to the most recent Atom processors. While the SoC will feature USB 3.0, it will not embrace SATA-6G or PCI-E 3.0. The CPU will go up to quad core units that will be 50% to 100% faster than current parts. These new chips will also introduce a boost functionality (think desktop Turbo Boost) that will run the frequency equal to or greater than 2.7 GHz.
Power is of course the primary concern, and these products will be offered from 3 watts and below (Bay Trail T) and up to 12 watts (Bay Trail D) These products will not be competing with the Haswell products which are rumored to get around 10 watts at the very lowest.
While Intel has been slow to react to the mobile push, they are starting to get that ball rolling. It will be very interesting to see if they can move fast enough to outrun and outwit the ARM based competition, not to mention AMD’s latest 28 nm products that will be released in the first half of 2013.

Leaked Intel Roadmap: Pretty Much No Changes
Subject: General Tech, Processors | January 3, 2013 - 06:00 PM | Scott Michaud
Tagged: Intel, haswell, Ivy Bridge-E
Intel creates a bunch of roadmaps as portions of their corporate slideshows and similarly to their development cycles: they get leaked like clockwork.
Last quarter’s roadmap revealed intentions for Intel to release the higher-end Ivy Bridge-E processors a whole quarter after dropping non-enthusiast Ivy Bridge from retail. That leak ended speculation from the prior quarter about the fate of Ivy Bridge-E with Haswell and Sandy Bridge-E pushing Ivy Bridge out of Intel’s second quarter 2013 lineup. After all, would Intel push higher-end SKUs of obsolete components? Would they just skip to Haswell-E? Could Sandy Bridge-E be slowly eaten away by the Xeon and lower end markets and left without a replacement? Apparently not the latters.
This quarter was much less dramatic but still interesting none-the-less.
I cannot Haswell-E'sburger.
The most obvious data point to pull from this slide is that nothing changed; information was only added. Ivy Bridge-E is still on target to launch a little less than a year from now. What we were given is expected SKUs names of the Haswell parts.
From i5 up to Sandy Bridge-E we will have approximately 5 SKUs ranging from the i5-4570 up to the i7-4770K. Room is still left for SKUs above the i7-4770K and the i5-4670K although Intel does not show any direct intentions to produce such chips. WCCF Tech believes from previous rumors that Ivy Bridge-E will consist of four SKUs: i7-4930, i7-4960, i7-4970, and i7-4990.
I also cannot Haswell at all???
Intel’s lower-end roadmap was also leaked within the same post. Apparently Ivy Bridge has more legs in that price range with Haswell being delayed for a quarter for Pentium and i3 processors. Haswell is completely absent in the Celeron price point with the original Sandy Bridge sticking around for a whole year from now.
This clearly is not a panicked situation for Intel on the high-end. Three leaked roadmaps in a row show for all practical purposes the same identical vision. I will be curious to see how performance compares between Ivy Bridge-E and its older little brother Haswell; clearly Ivy Bridge-E will make more sense from the point of view of RAM-intensive applications, but will certain applications be able to better utilize Haswell and its new architecture?
Who do you think will win in a fistfight, Ha’s well Ghul or Poison Ivy Bridge-E?
The AMD Closed Loop System
Closed loop water cooling is not new, but it certainly is a pretty hot topic now. Some of the first units out there had some interesting issues (like internal corrosion clogging everything up), but once those teething problems were solved the closed loop systems turned out to be pretty effective and easy to install. Initially these units had the performance of a top end air cooler, but with a lot lower noise. The latest generation of liquid cooling systems (LCS) is now further improved and provides performance approaching that of larger, more complex cooling systems. These products will not replace exotic systems like phase change, but they provide a lot of cooling in a fairly decent sized package.
Clean lines and graphics give this box a striking look without being tacky.
Last year with the introduction of the AMD FX-8150, AMD decided to create a SKU which not only included the CPU, but also a fairly robust LCS. This unit is based on an Asetek design which features a double wide cooler/reservoir with the push-me/pull-ya fan combination. Other manufacturers offer this particular product under a variety of names, but this is simply an AMD FX branded unit with some small cosmetic changes to differentiate it from other units.
AMD will eventually offer this cooler with the new Vishera based FX-8350 CPU (or at least we assume they will), and we wanted to take this combination out for a spin. In our FX-8350 review we did not hit the overclocking targets that AMD had set. In most literature that we were provided AMD stated that most FX-8350 parts would be able to hit around 5 GHz with some aggressive cooling. In our review I was able to get to around 4.6 GHz max and around 4.5 GHz stable with better than average cooling. The results were not as impressive as we had hoped, but we again did not have a top end cooling solution such as what AMD provides with this particular LCS.
With a brand new LCS in hand, I retested the FX-8350 to see how hard it could be pushed. I also wanted to see how this particular unit performance in terms of thermal properties. The results were quite surprising for me, as this is my first real experience with a LCS.

Too New for GNU: Development Not Always Smooth as Cilk

Due to Phoronix being particularly interesting lately, how would you like a little more open-source news?
GCC is one of the most important compilers for C/C++-based software due to its ubiquity both in where it can run as well as where it can compile to. Intel has a lot of experience developing for compilers, to say the least. Creating a competing product does not stop Intel from contributing to the project, however.
Aww, looks like he wants a hug.
Intel created C/C++ language extensions known as “Cilk Plus” designed to help developers parallelize their code on multithreaded processors. Both the compiler and run-time portions of Cilk Plus has been made open source and were submitted to be included into GCC. Unfortunately, for reasons which are currently unclear, GCC completed development of version 4.8 of their software without the inclusion of Cilk Plus.
Patches developed by Intel have been available since the summer awaiting approval from the official maintainers of GCC. Because the deadline passed without inclusion of the completed code, we will allegedly need to wait until at least 2014 -- maybe longer -- before Cilk Plus has another chance to be included in the GCC.
NVIDIA Tegra 4 Details Revealed By Leaked Slide
Subject: Processors, Mobile | December 19, 2012 - 03:26 AM | Tim Verry
Tagged: wayne, tegra 4, SoC, nvidia, cortex a15, arm
Earlier this year, NVIDIA showed off a roadmap for its Tegra line of mobile system on a chip (SoC) processors. Namely, the next generation Tegra 4 mobile chip is codenamed Wayne and will be the successor to the Tegra 3.
Tegra 4 will use a 28nm manufacturing process and feature improvements to the CPU, GPU, and IO components. Thanks to a leaked slide that appeared on Chip Hell, we now have more details on Tegra 4.
The 28nm Tegra 4 SoC will keep the same 4+1 CPU design* as the Tegra 3, but it will use ARM Cortex A15 CPU cores instead of the Cortex A9 cores used in the current generation chips. NVIDIA is also improving the GPU portion, and Tegra 4 will reportedly feature a 72 core GPU based on a new architecture. Unfortunately, we do not have specifics on how that GPU is set up architecturally, but the leaked slide indicates that the GPU will be as much as 6x faster than NVIDIA’s own Tegra 3. It will allegedly be fast enough to power displays with resolutions from 1080p @ 120Hz to 4K (refresh rate unknown). Don’t expect to drive games at native 4K resolution, however it should run a tablet OS fine. Interestingly, NVIDIA has included hardware to hardware accelerate VP8 and H.264 video at up to 2560x1440 resolutions.
Additionally, Tegra 4 will feature support for dual channel DDR3L memory, USB 3.0 and hardware accelerated secuity options including HDCP, Secure Boot, and DRM which may make Tegra 4 an attractive option for Windows RT tablets.
The leaked slide has revealed several interesting details on Tegra 4, but it has also raised some questions on the nitty-gritty details. Also, there is no mention of the dual core variant of Tegra 4 – codenamed Grey – that is said to include an integrated Icera 4G LTE cellular modem. Here’s hoping more details surface at CES next month!
* NVIDIA's name for a CPU that features four ARM CPU cores and one lower power ARM companion core.
