Intel Ivy Bridge-E: compatible X79 and LGA 2011?

And if the Ivy Bridge-E is compatible with the recently launched LGA 2011?

So just to test the Sandy Bridge-E Intel that are slow to point the tip of their nose Server versions, a slide from a presentation by leaked internal depth Xfastest reveals the existence of Ivy Bridge-E ... Remember, the Ivy Bridge are the future Intel processors, the Core i third generation that will be engraved in 22 nm.

These Ivy Bridge-E models are therefore high-end of the new series of processors, and where the slide is very interesting is that it suggests that these Ivy Bridge-E x79 chipset could use the d Intel and could therefore be backwards compatible with all motherboards with socket LGA 2011 now coming out for Sandy Bridge-E. This would allow the socket to have a greater than expected longevity, and enhance the interest of a sudden the platform Intel has just launched.

If this compatibility is confirmed by Intel, it means that the founder is to increase the longevity of its sockets. A note when the current LGA 1155 processors will accommodate Ivy Bridge. Ivy Bridge-E of which should be available in late 2012 in all probability. Remains to be seen, as can be expected, these processors incorporate 8-core assets.

Xeon drawn from Sandy Bridge-E arrive

Why are the equivalent of Sandy Bridge Servers-E Xeon slow to get out? Here are some ...

There a few days of this, we offered you the test of Intel Sandy Bridge-E. A total of eight cores "hyperthreading", so 16 rows of parallel processing, coupled with 20 MB of L3 cache, supported by four-channel DDR3 and two QPI channel for communication between processors, managing forty lines PCI Express version 3.0 more DMI2 embedded controller to manage the input / output. Impressive. Some will say that the Westmere-EX are more powerful. Yes, but the TDP emerged and consumption is not the same on this new generation of processors.


By cons, we do not always get these super processors for processing units in the drawers of Rue-Montgallet. The founder says they have some problems, especially on the new chipset Patsburg, the virtualization engine and the management of ports SAS, the world wide standard servers. But if the latter tests are successful, the next batch (C2 Stepping) should be available in February 2012, without elaborating.

Another major issue on which Intel has floored, the consumption of the devices associated with the processor, such as cache controllers or I / O or memory controller is now integrated into the processor. All this requires a lot of juice, for this reason also that the version "Desktop" has only six instead of eight cores, for example. It is therefore understandable that the frequencies of some processors are scaled down to meet the specifications for the TDP announced.

But the technical improvements of these new architectures can improve performance against previous generations. To correct this, it is expected that in the middle of the second quarter of 2012, a new revision (D-Stepping) will be released. When the chipset Patsburg finalized, version 3.0 of the PCI-Express has erased the problem of backward compatibility and then the frequencies of the processors may be revised upwards.

This architecture finally coming of age for PC and for the Pro, Ivy Bridge will arrive shortly after, in 2013, although it is rumored that they could get to the end of 2012 ...

The price of the next CPU Sandy Bridge-E d�voil�, but without Heatpipe!

The succession of the Core i7 is running, prices come to be informally revealed by our colleague VR-Zone.

Reliable source, prices were not surprising and it switches just the price of the Sandy Bridge ancient on the new Sandy Bridge-E (reminder: E for enthusiast, or French, amateur performance.) so to replace the Core i7 990 X by 3960X, the Core i7 980 by the 3930K and finally the Core i7 960 by the 3820.

We are thus left with a Core i7 3820, the smallest of the three, with a frequency of 3 database, GHz (Quad-Core / 8 Thread with 10 MB of L3 cache) and a maximum of 3, 9GHz with the Turbo mode, all for a price of 294USD...
The second Core i7 3930K is a hexacore with 12 Thread running at 3 GHz base and 3, 8 GHz with the Turbo mode and equipped with 12Mo of L3 cache at a price of 583USD.
And the third, the most powerful of the three, is the the 3960X sold to 999USD (model 6 hearts / 12 Thread with Schoolhouse of L3 cache) with frequencies ranging from 3, base to 3 GHz, 9GHz in Turbo mode.

All three are mounted on Socket LGA 2011 with the Chipset X 79, worthy successor of the couple LGA1366 / X 58, and have a TDP of weighing, they will be engraved in 32nm.Small detail, the constructor calls well feed its processors with a certified feed 80 + minimum.

However, Intel has decided not to sell the Sandy Bridge-E processors with a heatpipe. This is due to the fact that these processors are destined for a certain category of persons, which of course has a heatpipe with efficiency, both in terms of cooling and noise from a stock version. With a TDP of weighing it fully understands that the heatpipe of Intel will struggle to keep the fresh configuration.

Sandy Bridge-E, the I7-3960X would be 47% faster than the I7 - 990 X

 

 

 

 

 

 

 

 

 

Two charts published by the Donanimhaber.com site reveal the performance of the model of the future Sandy Bridge-E platform.Sandy Bridge-E will be the next round of top processors range from Intel using the new socket LGA-2011 from replace the set of processors on socket LGA-1366 for call back.

Currently high-end consists therefore of the I7-990 X EE (Extreme Edition). It is composed of six hearts with the support of the Hyper-Threading, or twelve Threads. He is running at 3.460 Mhz and monte 3.730 Mhz in Turbo Mode supported by 12 MB L3 cache. The memory controller manages the DDR3 on three channels at a frequency of 1066 Mhz. All for a TDP of 130 Watts.The leak is the I7-3960X EE (Extreme Edition). It will be with respect to him composed of six hearts with the support of the Hyper-Threading or twelve Threads also. He will be running at 3,300 Mhz and will rise to 3.900 Mhz mode Turbo, or nearly 4 GHZ! Backed up by a 15 MB L3 cache. The memory controller always bear the DDR3 but on four channels at a frequency of 1333 Mhz. The HRT will be the same or 130 Watts.
Tests on the first chart show that on Cinebench 11.5 the I7-3960X EE would be 13% more efficient than the I7-990 X, 12% more efficient on POV - Ray 3.7, 36% on the physics of 3D Mark 11 test score and finally 15% better on ProShow 4.5.The second graph shows a growth of 34% in Integer and 65% in decimal floating on SPEC CPU 2006, which measures the bandwidth memory.

It also shows that on the AVX instruction set tested by Sandra 2011 benchmark performance would be an increase of 92% in multimedia.
Regarding bandwidth memory, Sandra 2011 view Quad-Channel 111% higher performance than the Triple-Channel.The average of all these gains represent 47.25% of additional performance.

Still waiting for the end of the year, there was more than expected temperatures to warm us up with some less synthetic benchmarks, and see what would be the daily earnings.

The Sandy Bridge-E always planned for Q4

The launch of the future Core i7 Sandy Bridge-E socket LGA-2011 is always set to the end of the year...

Intel to launch new high platform of range for the general public at the end of the year. In the heart of the latter, will be Sandy Bridge-E processors, which operate the socket LGA-2011. Our colleagues of Donanimhaber come to hand over a new leaf confirming the names of these processors, as well as their time of arrival.

The Core i7-3820 will be the most accessible model, it should be proposed at a rate similar to that of the i7-960 ($294). The Core i7-3930K should be a CPU multiplier coefficients are free. An estimated $ 583 official tariff. Finally, the Core i7-3960X will be the Extreme of this future range declination, and it will be proposed at $ 999. Intel should launch these solutions over the last three months of the year. They should be supplanted in the second quarter of 2012, just after the launch of the first Ivy Bridge processors socket LGA-1155.It should be noted that once more the launch of the Sandy Bridge-E on the fourth appears to confirm, il may motherboards accompanying these processors are amputees of certain features, pending a fuller review. Question is if these two chipsets will be X 79 Express, or if Intel will launch any Z79 Express...

Good and bad surprises of the Sandy Bridge-E

The frequencies and caches of three Sandy Bridge-E models have appeared on the canvas. The Core i7-3960X will be a processor with six cores rotating at 3.30 GHz and 3.9 GHz in Turbo mode. It has a 15 MB L3 cache. It should be the most expensive of all and probably cost in the $1,000. The Core i7-3930K will have the same number of cores, but lower frequencies. It will turn to 3.20 GHz in normal mode and 3.80 GHz in Turbo mode. It will have 12 MB L3 cache. Finally, the last is a processor quad core responding on behalf of Core i7-3810. It will turn to 3.60 GHz and will have a turbo mode of 3.9 GHz and 10 MB of L3 cache.

This information comes from the Donanim Haber site and if they are correct, this would mean first that Intel would have decided to amend the nomenclature for the Sandy Bridge-E with the number three at the top of each model. It recalls that it had introduced a nomenclature to four digits with the Sandy Bridge which are designated as Core ix - 2xxx where they are not declined in Pentium or Celeron version. The idea of a change in nomenclature for the Sandy Bridge-E was issued last June, but at the time, talked about the use of the name Core i8.Intel have decided to designate the Sandy Bridge-E as a new architecture, which is not accurate. The Sandy-Bridge-E are primarily the Sandy Bridge high range requesting a Socket LGA 2011. In addition, according to the latest information published on the site VR-Zone, Intel would lower the characteristics of motherboards X 79 to extricate its product before the end of the year.

Earlier this month, rumors claimed that the Sandy Bridge-E were delayed and had to go out to these 2012 (cf. "The Sandy Bridge-E pushed early 2012"). The reasons for the delay were unknown. Today, the sounds of corridors say that Intel would be problems with the X 79 chipset that meets for code Patsburg-X, which was similar to the Patsburg-D chipset with a few changes to the consumer market. Patsburg D is high range for the Sandy Bridge - E Xeon chipset. It has eight ports SAS - SATA 6 Gb/s and it uses link 4 x PCI-Express 3.0 to connect the SAS ports to the CPU and optimize the performance of storage solutions. In response to its problems of development and his desire to leave the Sandy Bridge-E before the end of the year, the 79 X should be demoted to a B Patsburg manages only four SAS ports - SATA 6 Gb/s. PCI-Express 3.0 would also abandoned.If these information are correct, this means that the Sandy Bridge-E platform would lose some of its appeal. These changes will not impact on the performance in General, but the lifespan of the platform could be reduced, which is more harmful on the premium system which is supposed to last until the second half of 2013.These changes last minutes we also require to ask if the integration of the Sandy Bridge-E in the ix-3xxx Core family which should be mainly inhabited by the Ivy Bridge is sound. It risk primarily to confuse the consumer while the new architecture, which should arrive in the second quarter of 2012 will support PCI-Express 3.0.

In the meantime, the three processors in flight have all supported the HyperThreading and all a 130 W TDP. The X refers to Extreme Edition design and K points to an editable multiplier. These information are consistent rumors that we reported last May (cf. "Rise in frequency for the Sandy Bridge-E step"). Intel frequencies remain cautious, but these processors are designed to integrate configurations very high range, Intel expects surely overclockent consumers themselves their processor.
