Core 2 Quad QX6700 desktop vs Core i7-2620M laptop

post #1 of 11
Thread Starter 
At work, I have an HP xw4400 Workstation with the following specs:

Intel Core 2 Quad QX6700 2.66GHz
4GB RAM 333.3MHz DDR2 dual-channel kit
Windows 7 Ultimate 64-bit
nVidia Quadro FX 1500 (for dual monitors)

I multi-task like crazy, typically running Visual Studio 2008 (often two instances running at once for different projects), SQL Server Management Studio, Office 2010 apps (Outlook up all the time) and often have a Virtual PC running Windows XP for some legacy development.

I just got my hands on an HP EliteBook 8460p to take with me to meetings:

Intel Core i7-2620M 2.7GHz
3GB DDR3 666MHz RAM
Windows XP Pro 32-bit (can put whatever I want on it)
Intel HD3000 graphics (sandy bridge)

Would it be a good idea to give up the workstation for the laptop for all my development needs? I can get a docking station for it, so it will still handle dual monitors, and graphics performance isn't important. I've just never had a laptop available to me before that could handle my workload, so I wasn't sure about this one.

The i7 is a formidable processor for sure you can turbo boost that particular one to 3.3 ghz I believe, So it can most likely handle that work load, those programs aren't super demanding so its probably just a matter of

1 storage space

and 2 do u want to unhook a laptop from 2 monitors whenever you need it somewhere else?

But if the qx67 handles them well why even get rid of it?

Well, that's just it. I have been a bit less than satisfied lately by the performance of the PC. I was just wondering if the i7 would provide a noticeable improvement.

The 2620M core i7 is a 2 cores CPU with 2 Logical threads, so basically it is 2 cores vs 4 cores on the qx6700, so you will not notice a big difference, in my opinion the qx6700 will perform a bit better or maybe they will perform the same as the Sandy Bridge is better clock-for-clock.

Just for kicks, I fired up an instance of Super Pi on each core (incl. 4 on the i7). The QX6700 took 20:14 to complete, while the i7-2620M finished in 11:10. How relevant is that?

to me it's not relative at all,

here's a screen shot from my 2500k @ 4.5ghz and my 560ti

here's one on my QX9770 with the 260's in it

same settings

In single thread performance you should notice a big difference, but MT may be a wash since its 4 cores v. 2.

SuperPi only utilizes 1 core so like I said above, for ST get the new dual core. For MT it may be a wash... I'm thinking the 2600 will still be faster because of TB and it's superior ST performance.

If you want the biggest gains then get an SSD specifically the Crucial M4. Getting an SSD is the single biggest improvement that you can make to your system short of upgrading to a SNB @ 5Ghz from a Pentium 4 @ 1.8Ghz.

Wow I didn't realize the i7m's were only dual core I thought they were quads and sixes, they are faster tho, but for multiple programs you cant beat the quad

Only lower end i7m's are duals (2620m and below), 2630qm and up are quads.
