Intel used since the year 1998 the brand name for Xeon server
processors. Today also models for workstations marketed under this
name. Both are based on the respective desktop processors of the
corresponding generation. Despite the fundamental similarities,
they sometimes use their own base or chipsets. Due to a large
variety of available processors, the naming scheme affects
initially confusing. Therefore, we have listed the individual
series and their features for you below, where you can orient
yourself when buying. With us you get used Intel Xeon processors
that have two, four or more...
cores, and refurbished servers and workstations that are already
equipped with a Xeon CPU.
These processors have between two and six physical cores that allow
for few models hyperthreading twice the number of threads. They can
be used, depending on the model, for example, on a pedestal 775,
1136 or 1156 motherboard, but not in conjunction with other
processors. The maximum clock frequency of 3.76 GHz and L2 cache
with 12 MB provide the necessary computing power and faster than
latches are up to 32 GB DDR3 memory support. In the field of
workstations and servers, especially convenient entry-level models
are thus possible, yet offer sufficient computing power for small
workgroups or remote offices.
Made for dual-processor systems that allow these models with 3.86
GHz at first glance only a slightly higher clock frequency. But who
needs a great deal of memory for specific applications, for
example, can strike the Intel Xeon E5502. Although this provides
only a clock of 1.86 GHz, but can it handle up to 144 GB of DDR3
memory and supports this with ECC function. In addition to several
other functions in the area of ??virtualization and power
management multiprocessing capability remains the biggest advantage
however. These are used models with up to six cores in the socket
771 or 1366 of a motherboard.
Here, there are exactly three models, which offer four, six and
eight cores. It supports any model of hyper-threading and
virtualization professional. The maximum cache is 18 MB and the
clock frequency of 2.4 GHz, which is enough power for most
applications available, especially since several CPUs can be used
in a system with base 1567.
7000 series For use in multi-processor system with
socket 604 or 1567 Xeon CPUs this work with a maximum clock
frequency of 3.5 GHz. In addition, the cores are up to 16 MB L2
cache or a full 24 MB of L3 cache to the side. In terms of
comprehensiveness, are virtualization and energy management in
special focus. However, the Hyper-Threading technology is in some
models already enabled. If you want to help your system to
additional computing power, you can do this very inexpensively
through our used Xeon processors.
This series is now available in the third one because it is the
pendant to the desktop models of the Core i series. The current
version number, you agree to the attached abbreviation of the model
number, such as v2 in the Intel Xeon E3-1220L. The version
specifies the process on which microarchitecture based CPU. So, for
example, is v3 for Haswell. Although a higher version is usually
more efficient, but the actual differences can be very small. Basic
work all models with up to 32 GB of DDR3 memory and depending on
the version up to 4.1 GHz Turbo Frequency. With Hyper-Threading,
four or eight logical cores ready to have as a fast cache for up to
8 MB of Intel Smart Cache. The biggest advantage of some models,
however, is the low thermal power dissipation of up to 20 W and
other functions to save energy.
As with the E3 family is also a relationship to the desktop models
of the Core i series. However, you have here a wider choice, as up
to 12 physical cores are possible, which in turn offer
hyperthreading twice the number of threads. The core frequency is a
maximum of 3.6 GHz and is supported by up to 30 MB Intel Smart
Cache. Depending on the type of memory are also 768 GB of ECC DDR3
RAM possible. So power Technically you are open to all
possibilities. Depending on the model, two or four CPUs can be
operated together in a system that has the appropriate number of
bases of type 2011.
The current high-performance series of Xeon processors technology
offers up to 15 physical cores plus Hyper-Threading. Of course, but
also the models with six, eight, ten or twelve cores are available.
The core frequency of 3.7 GHz and 30 MB cache are not necessarily
far ahead of its predecessors, but offer these models can also in
other areas. For additional approximately 1.5 TB of DDR3 ECC memory
are possible. Regarding the functional scope as almost all
functions are available that can be used for virtualization and
data security, as VT-x, VT-d, Intel AES-NI and Secure Key. For
particularly demanding applications up to eight processors can be
run in a server. This depends on the particular CPU model and of
course the motherboard of the server.
information about the model numbers
Occasionally, individual letters are in front of the model number.
This point in particular to the TDP of the individual processors.
The order of increasing consumption is as follows:
L: less than 65 W
E: 65 to 90 W
X: 90 W
W: 130 W
The first digit of the model number is defined in the rule is
appropriate for the type of systems, the processor. A 3 stands for
one processor per system, a 5 for two-processor systems, and a 7
for multiprocessor systems. The following numbers indicate
generation and functions. While here, a higher number is often
better, but you should, if appropriate, inform what features you
get with the model and if you use this at all in everyday life.
