[H]ard|OCP reviewed Intel's brand new Extreme processor, the Haswell-E i7-5960X as weill as posting a large amount of Intel's launch slides detailing the new features present in this series of CPU. As you can see from the picture they used the same funky white ASUS motherboard which Ryan used in his review but chose a Koolance EX2-755 watercooler as opposed to the Corsair H100i which allowed them to hit 4.5GHz with 1.301v CPU core voltage, slightly lower than Ryan managed. In the end, while extremely impressed by the CPU they saw little benefits to gaming and recommend this CPU to those who spend most of their time encoding video, manipulating huge images and of course those who just want the best CPU on the planet.
"There are many members of the "1366 X58 Enthusiast Overclockers Club" that have been waiting with bated breath for Intel's launch of the new X99 Express Chipset and new family of Core i7 Haswell-E processors. All this new hardware comes bundled with brand new DDR4 RAM technology packing huge bandwidth as well."

Pushing the 8 Cores
It seems like yesterday when I last talked about an AMD refresh! Oh wait, it almost was. Some weeks ago I was able to cover the latest AMD APU offerings that helped to flesh out the Kaveri lineup. We thought AMD was done for a while. Color us wrong. AMD pulled out all the stops and set up an AM3+ refresh! There is a little excitement here, I guess. I am trying to contain the tongue-in-cheek lines that I am oh-so-tempted to write.
AMD is refreshing their FX lineup in the waning days of Summer!
Let me explain the situation from my point of view. The FX lineup for AM3+ has not done a whole lot since the initial release of the Piledriver based FX-8350 and family (Vishera). Piledriver was a pretty significant update from Bulldozer as it slightly improved IPC and greatly improved power consumption (all the while helping to improve clockspeed by a small degree). There were two updates before this one, but they did not receive nearly as much coverage. These updates were the FX-6350 and the FX-9000 series. The FX-6350 is quite popular with the budget enthusiast crowd who still had not moved over to the Intel side of the equation. The FX-9000 series were OEM only initially and reaching up to $1000 at the high end. During that time since the original Vishera chips were released, we have seen the Intel Ivy Bridge and Haswell architectures (with a small refresh with Haswell with the 2nd gen products and the latest Socket 2011 units).

Though my review of the Intel Core i7-5960X Haswell-E processor was posted earlier today, we hosted a live stream later in the afternoon where Allyn and I talked about the launch. We were also able to welcome Matt Dunford, Princpal Evangelist at Intel to talk about his role in the Haswell-E release, the future of the platform, how DDR4 memory fits into it all and much more.
The video is embeded in the processor review now as well but I have included it separately below for those of you that want to jump straight in.
My thanks goes out to Matt from Intel for joining us on the live stream and to all the viewers that came by to submit questions and participate!

The Tech Report took the new i7-5960X, Asus X99 Deluxe, 16 GB of Corsair Vengeance LPX DDR4, a Kingston HyperX SH103S3 240GB SSD and a XFX Radeon HD 7950 DD and set it loose on the test bench. The results were impressive to say the least, especially when they moved on from games to test productivity software where the Haswell architecture really shines. When they attempted to overclock the CPU they found a hard limit feeding the processor 1.3V and running 4.4GHz, any faster would cause some applications to BSoD. On the other hand that applied to all 8 cores and the difference in performance was striking.
Also make sure to read Ryan's review to get even mroe information on this long awaited chip.
"Haswell-E has arrived. With eight cores, 20MB of cache, and quad channels of DDR4 memory, it looks to be the fastest desktop CPU in history--and not by a little bit. We've tested the heck out of it and have a huge suite of comparisons going to back to the Pentium III 800. Just, you know, for context."

Revamped Enthusiast Platform
Join us at 12:30pm PT / 3:30pm ET as Intel's Matt Dunford joins us for a live stream event to discuss the release of Haswell-E and the X99 platform!! Find us at http://www.pcper.com/live!!
Sometimes writing these reviews can be pretty anti-climactic. With all of the official and leaked information released about Haswell-E over the last six to nine months, there isn't much more to divulge that can truly be called revolutionary. Yes, we are looking at the new king of the enthusiast market with an 8-core processor that not only brings a 33% increase in core count over the previous generation Ivy Bridge-E and Sandy Bridge-E platforms, but also includes the adoption of the DDR4 memory specification, which allows for high density and high speed memory subsystems.
And along with the new processor on a modified socket (though still LGA2011) comes a new chipset with some interesting new features. If you were left wanting for USB 3.0 or Thunderbolt on X79, then you are going to love what you see with X99. Did you think you needed some more SATA ports to really liven up your pool of hard drives? Retail boards are going to have you covered.
Again, just like last time, you will find a set of three processors that are coming into the market at the same time. These offerings range from the $999 price point and go down to the much more reasonable cost of $389. But this time there are more interesting decisions to be made based on specification differences in the family. Do the changes that Intel made in the sub-$1000 SKUs make it a better or worse buy for users looking to finally upgrade?
Haswell-E: A New Enthusiast Lineup from Intel
Today's launch of the Intel Core i7-5960X processor continues on the company's path of enthusiast branded parts that are built off of a subset of the workstation and server market. It is no secret that some Xeon branded processors will work in X79 motherboards and the same is true of the upcoming Haswell-EP series (with its X99 platform) launching today. As an enthusiast though, I think we can agree that it doesn't really matter how a processor like this comes about, as long as it continues to occur well into the future.
The Core i7-5960X processor is an 8-core, 16-thread design built on what is essentially the same architecture we saw released with the mainstream Haswell parts released in June of 2013. There are some important differences of course, including the lack of integrated graphics and the move from DDR3 to DDR4 for system memory. The underlying microarchitecture remains unchanged, though. Previously known as the Haswell-E platform, the Core i7-5960X continues Intel's trend of releasing enthusiast/workstation grade platforms that are based on an existing mainstream architecture.

Take it with a grain of salt as always with leaks of these kind but you will be interested to know that videocardz.com has what might be some inside information on Haswell-E pricing and model numbers.
Intel i7 / X99 Haswell-E pricing:
- Intel Core i7 5960X 8C/16HT – 40-lane PCI-Express support (x16 + x16 + x8) — $999
- Intel Core i7 5930K 6C/12HT – 40-lane PCI-Express support (x16 + x16 + x8) — $583
- Intel Core i7 5820K 6C/12HT – 28-lane PCI-Express support (x16 + x8 + x4) —– $389
As you can see there is a big jump between the affordable i7-5820K and the more expensive 5930K. For those who know they will stick with a single GPU or two low to mid-range GPUs the 5820K should be enough for you but if you have any thoughts of upgrading or adding in a number of PCIe SSDs then you might want to seriously consider saving up for the 5930K. Current generation GPUs and SSDs are not fully utilizing PCIe 3.0 16x but that is not likely to remain true for long so if you wish for your system to have some longevity this is certainly something you should think long and hard about. Core counts are up while frequencies are down, the 8 core 5960X has a base clock of 3GHz, a full gigahertz slower than the 4790K but you can expect the monstrous 20MB cache and quad-channel DDR4-2133 to mitigate that somewhat. Also make sure to note that TDP, 140W is no laughing matter and will require some serious cooling.
Since the introduction of the Haswell line of CPUs, the Internet has been aflame with how hot the CPUs run. Speculation ran rampant on the cause with theories abounding about the lesser surface area and inferior thermal interface material (TIM) in between the CPU die surface and the underside of the CPU heat spreader. It was later confirmed that Intel had changed the TIM interfacing the CPU die surface to the heat spreader with Haswell, leading to the hotter than expected CPU temperatures. This increase in temperature led to inconsistent core-to-core temperatures as well as vastly inferior overclockability of the Haswell K-series chips over previous generations.
A few of the more adventurous enthusiasts took it upon themselves to use inventive ways to address the heat concerns surrounding the Haswell by delidding the processor. The delidding procedure involves physically removing the heat spreader from the CPU, exposing the CPU die. Some individuals choose to clean the existing TIM from the core die and heat spreader underside, applying superior TIM such as metal or diamond-infused paste or even the Coollaboratory Liquid Ultra metal material and fixing the heat spreader back in place. Others choose a more radical solution, removing the heat spreader from the equation entirely for direct cooling of the naked CPU die. This type of cooling method requires use of a die support plate, such as the MSI Die Guard included with the MSI Z97 XPower motherboard.
Whichever outcome you choose, you must first remove the heat spreader from the CPU's PCB. The heat spreader itself is fixed in place with black RTV-type material ensuring a secure and air-tight seal, protecting the fragile die from outside contaminants and influences. Removal can be done in multiple ways with two of the most popular being the razor blade method and the vise method. With both methods, you are attempting to separate the CPU PCB from the heat spreader without damaging the CPU die or components on the top or bottom sides of the CPU PCB.

Sorry for being about a month late to this news. Apparently, someone got their hands on an Intel Core i7-5960X and they wanted to see its eight cores. Removing the lid, they found that it was soldered directly onto the die with an epoxy, rather than coated with a thermal paste. While Haswell-E will still need to contend with the limitations of 22nm, and how difficult it becomes to exceed various clockspeed ceilings, the better ability to dump heat is always welcome.

While Devil's Canyon (Core i7 4970K) used better thermal paste, the method used with Haswell-E will be event better. I should note that Ivy Bridge-E, released last year, also contained a form of solder under its lid and its overclocking results were still limited. This is not an easy path to ultimate gigahertz. Even so, it is nice that Intel, at least on their enthusiast line, is spending that little bit extra to not introduce artificial barriers.

Tagged: X99, Intel, Haswell-E
Haswell-E, with its X99 chipset, are expected to launch soon. This will bring a new spread of processors and motherboards to the high-end, enthusiast market. These are the processors that fans of Intel should buy if they have money, want all the RAM, and have a bunch of PCIe expansion cards to install.
If you count the PCIe x1 slots, the table would refer to the first, third, fifth, and seventh slots.
To me, this is not too bad. You are able to use three GPUs with eight-lane bandwidth and stick a four-lane PCIe SSD on the last slot. Considering that each lane is PCIe 3.0, it is similar to having three PCIe 2.0 x16 slots. While two-way and three-way SLI is supported on all CPUs, four-way SLI is only allowed with processors that provide forty lanes of PCIe 3.0.
Gigabyte also provides three PCIe 2.0 x1 slots, which are not handled by the CPU and do not count against its available lanes.
Since I started to write up this news post, Gigabyte seems to have replaced their manual with a single, blank page. Thankfully, I was able to have it cached long enough to finish my thoughts. Some sites claim that the manual failed to mention the 8-8-8 configuration and suggested that configurations of three GPUs were impossible. That is not true; the manual refers to these situations, just not in the most clear of terms.
Haswell-E should launch soon, with most rumors pointing to the end of the month.

VIA subsidiary Centaur Technology is rumored to be launching a new x86 processor at the end of August based on the "Isaiah II" architecture. This upcoming chip is a 64-bit SoC aimed at the mobile and low power space. So far, the only known implementation is a quad core version clocked at up to 2.0 GHz with a 2MB L2 cache. Benchmarks of the quad core Isaiah II-based processor recently appeared online, and if the SiSoft Sandra results hold true VIA has very competitive chip on its hands that outperforms Intel's Bay Trail Z3770 and holds its own against AMD's Jaguar-based Athlon 5350.
The SiSoft Sandra results below show the alleged Isaiah II quad core handily outmaneuvering Intel's Bay Trail SoC and trading wins with AMD's Athlon 5350. All three SoCs are quad core parts with integrated graphics solutions. The benchmarks were run on slightly different configurations as they do not share a motherboard or chipset in common. In the case of the VIA chip, it was paired with a motherboard using the VIA VX11H chipset).
|Processor||VIA Isaiah II Quad Core||AMD Athlon 5350||Intel Atom Z3770|
|CPU Arithmetic||20.00 GOPS||22.66 GOPS||15.10 GOPS|
|CPU Multimedia||50.20 Mpix/s||47.56 Mpix/s||25.90 Mpix/s|
|Multicore Efficiency||3.10 GB/s||4.00 GB/s||1.70 GB/s|
|Cryptography (HS)||1.50 GB/s||1.48 GB/s||0.40 GB/s|
|PM Efficiency (ALU)||2.90 GIPS||2.88 GIPS||2.50 GIPS|
|Financial Analysis (DP FP64)||3.00 kOPT/S||3.64 kOPT/S||1.50 kOPT/S|
For comparison, The Atom Z3770 is a quad core clocked at 1.46 GHz (2.39 GHz max turbo) with 2MB L2 cache and Intel HD Graphics clocked at up to 667 MHz supporting up to 4GB of 1066 MHz memory. Bay Trail is manufactured on a 22nm process and has a 2W SDP (Scenario Design Power). Further, the AMD "Kabini" Athlon 5350 features four Jaguar CPU cores clocked at 2.05 GHz, a 128-core GCN GPU clocked at 600 MHz, 2MB L2 cache, and support for 1600 MHz memory. AMD's Kabini SoC is a 28nm chip with a 25W TDP (Thermal Design Power). VIA's new chip allegedly supports modern instruction sets, including AVX 2.0, putting it on par with the AMD and Intel options.
|Processor||VIA Isaiah II Quad Core||AMD Athlon 5350||Intel Atom Z3770|
|CPU||4 Cores @ 2.00 GHz||4 Cores @ 2.05 GHz||4 Cores @ 1.46 GHz (up to 2.39 GHz turbo)|
|GPU||?||128 GCN Cores @ 600 MHz||HD Graphics @ (up to) 667 MHz|
|Memory Support||?||1600 MHz||1066 MHz|
|L2 Cache||2 MB||2 MB||2 MB|
|TDP / SDP||?||25W||2W|
The SiSoft Sandra benchmarks spotted by TechPowerUp suggest that the Centaur Technology designed chip has potential. However, there are still several (important) unknowns at this point. Mainly, price and power usage. Also, the GPU VIA is using in the processor is still a mystery though Scott suspects an S3 GPU is possible through a partnership with HTC.
The chip does seem to be offering up competitive performance, but pricing and power efficiency will play a major role in whether or not VIA gets any design wins with system OEMs. If I had to guess, the VIA chip will sit somewhere between the Intel and AMD offerings with the inclusion of motherboard chipset pushing it towards AMD's higher TDP.
If VIA prices it correctly, we could see the company making a slight comeback in the x86 market with consumer facing devices (particularly Windows 8.1 tablets). VIA has traditionally been known as the low power x86 licensee, and the new expanding mobile market is the ideal place for such a chip. Its past endeavors have not been well received (mainly due to timing and volume production/availability issues of the Nano processors), but I hope that Centaur Technology and VIA are able to pull this one off as I had started to forget the company existed (heh).
