Intel Xeon E5-2600 Expands its v4 with 22 Core

With 22 Core, 14 nm engraving, security, and telemetry functions strengthened, Intel Xeon E5-2600 v4 meets the performance requirements of servers.

With a metronomic pace, Intel respects its timing for processor renewal for servers. Thus, unveils the successor of Xeon E5-2600 v3 that worked on the micro-architecture Haswell. For v4, Intel preferred the micro-architecture Broadwell instead of Haswell.

The latter is known in the world of mainstream processors and has been adapted to the world of data centers and especially the Cloud.

Hearts For Performance

This vintage is clearly marked by the performance. The chip can carry up to 22 cores with a clock frequency of 2.2 GHz per socket. Fleas are benefiting from a method of engraving in 14 nm against 22 nm for previous processors.

Intel promises 44% more performance as the turbo mode has been improved by allowing making changes in frequencies for vector calculus as cores through the AVX feature. Before, when we change the frequency of a core, all the others were capped on that value.

Today, it is possible to play on the frequencies, for example, a granularity to optimize the performance of one application over another.

On the management of the transactional memory, Intel reactivated the controversial TSX, which is to simplify the work of developers when programming with multiple threads. A bug in this feature had pushed Intel to disable TSX in the Xeon E5-2600 v3.

Enabling this feature was highly requested, particularly in the context of in-memory solutions such as SAP Hana. Always on the memory, the latest Xeon E5 chip supports up to 4 channels in DDR4 2400 MHz (against 2133 MHz previously).

Telemetry and security strengthened

For virtualization, Intel relies heavily on telemetry to adapt to the needs of the core’s workload. Thus, in its orchestration tool, Intel includes monitoring modules and allocation of bandwidth memory by core (MB) to prioritize workloads by core, as well as cache allocation technology (CAT) that enables developers to reserve the L3 memory.

The idea is to use telemetry to provide an SLA management solution on the VM. However, the first benefits from this orchestration are KVM and Xen and work is underway on VMware ESXi.

Security issues are never far away and Intel offers several services to strengthen the defenses of the processors. First encryption, the foundry worked on the acceleration of AES encryption and signatures and checks ECDSA, RSA, and DSA.

In addition, added the two instructions in ciphers i.e. ADOX and ADCX. For its part, RSEED help to generate random numbers, an important element of strong encryption. Finally, Intel integrates SMAP (Supervisor Mode Access), which prevents kernel banging on the user memory, increasing the risk of corruption.

In the end, Intel has a wide range of CPUs under the Xeon E5-2600 v4 series for servers…
