Today, November 14, there was a demonstration of some «rebirth», which is loved by many owners of modern computing systems, the Sandy Bridge microarchitecture. Intel continues to follow its «Tick-Tock» concept, according to which every two years production is transferred to a new, thinner process technology («Tick»), and a year later it presents to the public a new architecture, which is released using the already mastered technical process («Tick»). «). This time the high-end processors of the 2nd generation Intel Core i7 family class for enthusiasts and solving problems of maximum complexity, manufactured using a 32-nm process technology for platforms with a new processor socket 9, became the highlight of the program.
0775 Socket LGA 2011 .
New items are released during the «Tak» period and are in fact the completion of the development of the Sandy Bridge architecture for the current process technology. And next year, we expect the development of a new 22-nm process technology («Teak») and, accordingly, the entry into the market of Ivy Bridge.
It may be quite logical to ask how the developers achieved the performance increase. In order to answer it, you should look at the processor circuit. First of all, the CPU crystal was freed from the graphics component, which is by and large irrelevant for high-end class systems, and instead of it, 2 more computing cores were placed, capable of processing 2 threads each. Thus, the appearance of these «giants» occurred, the architecture of which was called Sandy Bridge-E .
Simultaneously with the increase in the number of active CPU cores, some reorganization of its other components also took place.
First of all, this affected the memory controller, which has now become 4-channel and nominal support for DDR3-1600 has appeared. If you look at the company’s existing products, then the «extreme solutions» for LGA 1366 had a 3-channel memory controller, and for the Sandy Bridge architecture itself, 2 channels are native. In addition to the memory controller, significant changes have also taken place in the PCI-Express 2.0 bus controller. Now it is equipped with 40 PCI-Express lanes compared to 16 in Sandy Bridge, but is still equipped with support for several video cards combined using AMD CrossFireX or NVIDIA SLI technologies, while configuration options can be very different: 2×16 and 1×8, 1×16 and 3×8 or 1×16 plus 2×8 and 2×4. Most likely, so many PCI-Express lanes will be in demand for servers with compute cards, additional RAID controllers, etc. installed. It was expected that the new processors would also support PCI-Express 3.0, but their current revision does not support the accelerated PCI-Express bus.
Due to the fact that new items have been released for the new platform, the appearance of a new set of system logic is also quite logical. Platforms with Socket LGA 2011 are equipped with the Intel X79 Express chipset (read more about it in the MSI X79A-GD65 (8D) motherboard review), which consists of a single chip and is connected to the processor by a DMI bus with a bandwidth of 20 GB / s. It supports 8 PCI-Express 2.0 lanes, 4 SATA 2.0 ports (3.0 Gb/s) and 2 SATA 3.0 ports (6.0 Gb/s) with the ability to organize RAID levels 0, 1, 10 and 5. The chipset also supports up to 14 USB 2.0 ports. But USB 3.0 and PCI support for Intel X79No. Additional SATA/SAS ports, USB 3.0 and PCI bus can be implemented by third party controllers.
At the moment, the second generation Intel Core i7 processor family has 5 models, while the new platform is supported only by two (Intel Core i7 3960X and Intel Core i7 3930K), which were presented today, and in the first In the quarter of 2012, another more affordable Intel Core i7 3820 processor is expected to be released.
5W typical for LGA 1155 CPUs and an unlocked multiplier.
Of the 2 CPUs presented today for testing, an engineering sample of the CPU Intel Core i7-3930K , which is positioned by the manufacturer for solving particularly demanding tasks and games, came to our laboratory for testing. As for the Intel Core i7-3960X, it is more suitable for overlock enthusiasts and is a kind of «replacement» for the Intel Core i7-990X Extreme Edition.
The retail packaging of the processor is as follows.
A quick glance at it is enough to immediately show that the processor it contains belongs to the model range of high-performance 2nd generation Intel Core CPUs.
The processor itself is not much different from its «brothers» by manufacturer. The processor cover of the retail Intel Core i7-3930K should have a main marking that helps identify the model, as well as the nominal frequency, cache size and power requirements.
On the engineering sample, only the clock frequency and the place of production are clearly indicated — Costa Rica.
It would seem that everything is the same, but there is one «but» — these are the dimensions. Pay attention to the dimensions of the processor itself in comparison with the CPU for LGA 1155 and LGA 1366. can not do without increasing the size of the crystal.
The back of the processor has undergone significant changes. Please note that the LGA 2011 and LGA 1155 processor sockets are absolutely unrelated, despite the fact that the processors are based on the same microarchitecture.
The processor socket itself on the motherboard looks like this.
Its distinctive feature is the presence of 2 clamping brackets, which is primarily due to the dimensions of the processor. For normal operation, it is necessary to ensure uniform contact between the CPU and the processor socket.
Due to the fact that along with the processors a new processor socket was actually announced, which differs significantly from the previous ones, proprietary cooling systems from Intel were also presented.
The cooling systems themselves will be sold in similar packages.
Please note that in the presentation slides the manufacturer mentions the compatibility of these cooling systems with processors based on the Ivy Bridge and Ivy Bridge-E , from which we can conclude that in the not so distant future, after the release of Ivy Bridge, CPUs will also be presented for enthusiasts — Ivy Bridge-E . Traditionally, an air cooling system is recommended for workstations that operate in nominal modes, and a water cooling system for overlockers. A distinctive feature for the LGA 2011 connector is the screw mount.

2 Based on the specification, we see that the not-so-high value of the processor frequency may well be explained by the use of a 4-channel memory controller that supports working with memory up to DDR3-1600. The change in throughput from 25.6 GB/s to 51.2 GB/s is a serious claim to increase computing capacity, but we can talk about a real increase in performance only after testing. The impressive size of the L3 cache indicates potentially good performance in archiving or encoding tasks.
Work in the nominal mode
Work in the TURBO BOOST
processor Intel Core i7-3930k refers to the Sandy Bridge family. In the nominal mode, it operates at a frequency of approximately 3200 MHz, while the core voltage is 1.152 V. Of course, a 4-channel memory controller is good, but one of the most frequently asked questions on the Internet is the lack of PCI-Express 3.
