Intel® Xeon® Processor E7-8800/4800/2800 Product Families Characteristics and Impact to Performance

EXECUTIVE SUMMARY

Just like many automobile manufacturers and other companies that have multiple

product lines within their product family, server processors have model numbers

to help distinguish the differences in features and delineate value. As your

business grows, so does demand for your products and / or services with

additional customers, users, and transactions that strain your current IT

infrastructure and back-end databases. The Intel® Xeon® brand helps customers

select the appropriate product line and family stack as their demand justifies it¹.

This paper focuses specifically on the Intel Xeon processor E7 family which is designed to be expandable and

scalable for larger deployments of business- or mission-critical workloads such as on-line transaction

processing, physical-to-virtual machine consolidation projects, business intelligence, customer relationship

management (CRM), and enterprise resource planning (ERP) / line-of-business applications that generate

revenue. The model numbers (see Figure 1) help differentiate the capabilities of the processors and in the

case of the Intel Xeon processor E7 product family, the wayness or maximum number of processors (CPUs or

sockets) in a node can be two, four, or eight (contrasted to the Intel Xeon processor E3 or E5 families, which

support only one or two/four processors, respectively). Performance may scale as the number of processors

installed (wayness) in a server is increased (up to 94% efficiency as published in this paper); but in a two-way

server, regardless of the actual processor wayness capability, the throughput application performance would

be expected to be the same.

MODEL NUMBERS AND

SCALABILITY

For the Intel Xeon processor E7 family,

processor models (also called SKUs) are

available in three wayness

configurations – two, four, or eight

socket native support (no third party

node controller required to connect the

Figure 1 - 2012 Processor Numbering Example

sockets together). Within a given Intel Xeon processor E7-xxxx SKU, the difference in wayness is irrelevant if

populated in only a two-socket node and corresponding performance differences are negligible. For example,

the top-bin Intel Xeon processor E7-8870/E7-4870/E7-2870 all have the same socket type (8) and the same

White Paper Intel® Xeon® Processor E7 Family Performance

number of users (typically matches the number of logical threads seen by the Operating System, OS)

simultaneously running a problem on a given server. The performance scaling is calculated by dividing the

resulting score from the maximum number of processors populated in one server by the score of the server with

n-way processors populated in another server configuration. So from 2- to 4- to 8-socket-based servers, the

perfect scaling would be four times, meaning that the number of users supported (or problems solved) in the 8-

socket server is four times more than what a 2-socket server could support. The efficiency is measured by how

close a scale-up server performs comparatively to that perfect scaling, which in this case is quite reasonable at up

to 94% efficiency (see Figure 4 below).

Figure 4 - Scaling of supported users on multi-processor servers⁴

The Intel Xeon processor E7-8870 can be populated in a 2-, 4-, or 8-socket server configuration. This is due to the

Intel® QuickPath Interconnect (Intel® QPI) that allows the processors to share resources by allowing all of the

components to access other components through the mainboard network. Similar to the Intel Xeon processor E7-

8870, the E7-4870 model supports 2- or 4-socket server configurations; but on the Intel Xeon processor E7-2870,

only 2-sockets can be populated in a server node (though multiple nodes can be joined together to form a larger

single server image ≥2S – see Figure 3 above).

There are no characteristics in each of the three processors noted above that differ, other than the wayness

capability. All three processors operate in the same number of available cores per socket, core frequency, Intel®

QPI speed, and cache structure (see Figure 2 above). Therefore, in a 2-socket server configuration, the

performance delta between the three will only be typical run-to-run variation due to a number of factors including

manufacturing variances that may affect the length of time the processors run above their marked frequency

using Intel® TurboBoost Technology. SPEC* allows for up to 1.75% variation. This hypothesis was confirmed

through testing using Intel internal labs and as seen in Figure 5 below as there is less than 0.5% difference in

performance between the three processors when in the same two-socket server configuration (see Table 1 below

for complete list of equivalent processor SKUs).

CONCLUSION

Servers are very complex machines, especially in the “big iron” class where multi-processor configurations are the

norm. The Intel Xeon processor E7 family is designed to support a multitude of shipping configurations and the

model numbering schema is attempting to clarify the wayness and feature choices that customers have. In the

current generation Intel Xeon

processor E7 family scalable

platform situation, the

performance throughput

increases at up to 94%

efficiency from 2- to 8-

sockets. However, in a two-

552

553

socket server configuration,

there is no appreciable

difference in performance

regardless of the processor

SKU chosen – Intel Xeon

processors E7-

8870/4870/2870 and others

shown in Table 1 above are

equivalent.
