Processor Xeon E3-1220 from Intel. Overview, characteristics

E3-1220 ревизии v5. The processor solution for high-performance workstations and budget-class servers is E3-1220 revision v5. The technical specifications of this chip are relevant at the moment, and it is produced by the most advanced process technology and has a low value of power consumption. It is this high-performance microprocessor solution and its capabilities that will be further discussed.

For the use of which servers this chip is aimed at?

The processor products for Intel's servers are currently distributed as follows:

• Ultra-budget servers and high-speed workstations are based on a single multi-core micro-processor device. E3-1220 в исполнении v5. It is to this group that the chip E3-1220, considered in the framework of this material, in the version v5 belongs .

• Server products of the middle class are based on configurations that include 2 to 4 CPUs.

• Well, to the premium level solutions, by default, devices that include more than 4 chips belong.

Contents of delivery

Intel Xeon E3-1220 - это ВОХ. The main delivery option, in which you can meet the Intel Xeon E3-1220 - it's BOB. It includes the following:

• Branded box of cardboard.
• Chip.
• Plastic box for safe transport of microprocessor solutions.
• Certificate of full compliance of this product with norms and standards.
• Branded cooler.
• User's guide in a truncated version.
• Thermal grease.
• A coupon with a warranty.

Reserve option - TRAIL. The cost in this case was lower for the reason that the manufacturer did not include a cooling system from the fan and the thermal paste.

Socket, architectural features, frequency values

E3-1220 модификации v5 - это LGA1151. The main socket for the E3-1220 version of v5 is LGA1151. Again, this chip can fully function only in motherboards with a set of C2XX chips that are designed to assemble workstations or servers. In the usual solutions of this class of series 1XX and 2XX, such CPUs will not function at all.

The code name for this microprocessor architecture is Skylake. The layout of this microprocessor solution is designed so that it includes 4 physical data processing clusters. At the same time there is no support for HT technology in this chip. Therefore, the number of cores is equal to the number of threads, that is, 4.

But the technology TurboBust in conjunction with such a CPU successfully operates. As a result, the frequency of the microprocessor changes dynamically. Its minimum value is 3.0 GHz, and the largest is 3.5 GHz.

The manufacturing process of the crystal, power consumption and temperature

Intel E3-1220 именно ревизии v5 является технология производства кремниевого кристалла. The key "chip" in the production of Intel E3-1220 is revision v5 is the technology of silicon crystal production. In this case, it is advanced and corresponds to the norm of 14 nm. It is due to the use of such an advanced process that this chip can boast a nominal value of a thermal package of 80 W.

Also the crystal dimensions are 37.5 mm X 37.5 mm. The highest temperature of this processor device is set by the manufacturer at around 67 ^o C. In reality, this parameter does not exceed 60 ^o C.

The voltage that is applied to the chip must be in the range from 0.55 V to 1.52 V. The latter value, as a rule, is determined by the level of complexity of the problem being solved and the current temperature of the semiconductor base of the CPU.

Cache, RAM subsystem

Xeon E3-1220 . Built-in fast memory subsystem of 3 levels boasts Xeon E3-1220 . The largest volume in this case has the last third level, in which you can place 8 GB of data and instructions.

This part of the cache is shared by all the components of the processor and the address space is the same for it. That is, all memory cells can store both data and instructions.

The second level allows you to place 1 MB of data and instructions. It is already divided into 4 parts of 256 KB. Each of these parts is directly tied to a specific kernel and can only store its instructions and data.

The capacity of the first level is 256 KB. They are divided into 4 segments of 64 KB. Each of them, like the second-level cache, is assigned to a certain computing unit. In this case, the memory is divided into 2 equal parts of 32 KB. One of them stores only data, and the second - the instructions of the CPU.

The controller of the random access memory is included by the manufacturer in the CPU. It is dual-channel and is aimed at working in conjunction with DDR4 modules. The chip frequencies in this case should correspond to 1866 MHz or 2133 MHz. You can also use faster solutions, but they will still work at the maximum possible frequency of 2133 MHz. The maximum amount of RAM installed by developers at around 64 GB. The bandwidth of the RAM subsystem corresponds to 34.1 Gb / s.

The cost. Reviews

E3-1220 v5 имеет высокую стоимость. Like any other Intel processor solution, the E3-1220 v5 has a high cost. In the version of the BOX configuration, it is estimated by the manufacturer at $ 203, while the more affordable TRAIL is $ 193.

It is very, very high price and is the main drawback of the decision. And this model at the moment is relevant and it can still be found on sale in a new state.

But the advantages of this server chip are:

• High energy efficiency.
• Perfect interaction.
• Flexible functionality, which allows it to be used both as part of server computers of budgetary level, and workstations.

Results

E3-1220 . To date, a really great processor is the E3-1220 . It is perfect for a budget class server.

Another possible application is workstations with a high level of performance. In all other cases, the use of this chip is unreasonable, either for economic reasons, or for an insufficient level of performance.
