Hi, I am planning to get a new workstation for different types of work, such as:
- Office Work (Excel, Outlook, etc.)
- Some VMWARE machines
- Password recovery software
- forensic tools
- Some Database work at least DB clients
- Data Analysis software

My two main configurations:
1 - Lenovo S30 with E5-1660 and Nvidia Quadro 4000 with SSDs and Sata disks
2 - Lenovo D30 with E5-2643 and Nvidia Quadto 2000 (might be able to get the 4000) and 1 additional SSD compared to option 1.
The prices are comparable but expect option 2 will be a little higher depending on GPU and number of disks.

It will be excellent if someone can advise on which one to choose based on my work above? I need to choose one asap. :)

Hi guys, any hint regarding my above question. Is a dual processor system more reliable and stable? or should I go for the single cpu E5-1660. I know that in single thread the 1660 wins over the dual E5-2643 by around 11 % and in overall cpu mark, the dual wins by 9 %. But dont know which one should I get from point of view work performance and reliability. I have never tried dual cpus on a workstation.

Hi Goldorak,

Did you buy the D30 at the end?

goldorak,

Dual CPU's >

1. the principal advantage to a dual CU system is when working with software that can use every thread. It's a complicated decision and my suggestion is to look into each application you use for multi-core use and assign a priority to it. If your primary application were rendering, which can use every thread, then yes, the dual Xeon would be useful and faster. A lot of analysis / simulation software as well as very complex 3D modeling, scientific like NAMD and MATLAB, and simulation can use all the threads too. Still, a surprising number of big complex programs are single-threaded such as Autodesk and Solidworks.

2. Besides more threads, dual CPU's also provide more PCIe lanes and RAM memory. If you are going to be using coprocessors like Tesla or Xeon Phi, then dual CPUs can get you up to seven PCIe x16 slots and there are quite a few dual motherboards off the shelf (Intel C602) that support 512GB of DDR3 ECC 1600.

Single CPU >

1. However, if your primary need is for speed in single-threaded programs, then the single CPU at a higher clock speed will be be an advantage. I use a dual Xeon quad core 3.16GHz Dell Precision, which I configured for rendering, but it seems rendering is less than 10% of my time, so the new system has a lowly quad core E5-1620 but that will run on the first two cores at 3.8GHz. It also much faster memory (1600 instead of 667) and disk system ( SSD and SATA III instead of mech'l and SATA II), so the experience of the new system is of a much, much faster one. It really shifts the polygons!

A little analysis of the options>

The dual quad-core are offering 50% more threads than the single six-core and the two E5-1643's cost about $2,800 to the E5-1660 at about $1,100. In Passmark CPU Benchmarks , dual E5-2643's are rated at No. 18 with a score of 13759.

http://www.cpubenchmark.net/cpu_list.php

The Xeon E5-1660 is No. 9, scoring 12468. That is, the E5-2643's perform at 110% of the E5-1660, but at more than 250% of the cost. This is a bit raw in terms of cost/ performance consideration, but means that the additional cores / threads need to be quite important to your work to justify the cost alone. In single-threaded program the E5-1660 will be faster due to the higher clock speed.

A suggestion:

If you find the eight cores / sixteen threads are an advantage, or in fact the more the better, consider buying a dual CPU system but populating it with a single Xeon E5-2687W. That runs at a slightly higher clock speed (3.1 /3.8) than the 2643 (3.3 / 3.5) and, importantly, has 8 cores / sixteen threads at a raw cost of about $1,950 as compared to the dual 2643's at $2,800. In passmark a single E5-2687W is rated No. 1, scoring 14586. This is compared to the dual 2643's at 13759, meaning that you can have the same core / thread count with higher performance at 70% of the cost. There is an upcoming E5-2687W V2 that is 3.4 / 4.0GHz >

It may a bit more than the original version.

This is disregarding the possible need for more PCIe slots, but I believe you could have a good Quadro- I'd suggest the K4000 (3GB), and perhaps an LSI SAS/ SATA RAID controller, and if necessary a network / port card, and so on. There should still be at least one or two more X16 slots for a Tesla or PHI co-processor.

In summary, unless Lenovo charges a huge premium for it, a single E5-2687W seems to solve every contingency with very high capabilities at a reasonable cost.

I might mention too, that there is the Xeon E5-1650 six-core @ 3.2 / 3.8 GHz and these sell for under $600 as OEM. There are a lot of Precision T3600's with these that do very well. The soon to be released E5-1660 V2 will run it's first core at 3.7GHz, but the 1650 top rate is still faster at 3.8GHz., so that's experientially the same or better performance at 54% of the cost.
