E6400 vs M2400

Hello,

First of all, I apologize for my English, I’m from Spain.

I’ve a Precision M20 for 3 years ago and I’m very happy with it. The laptop is very cool, quiet and powerful. Now, I’m thinking about buying another laptop soon and I don’t know if choose M2400 or E6400.

I work in IT Department of my company and I’m a student of Telecommunications engineering.

I usually work with my laptop about 10-14 hours daily (job and home/university), so it’s important for me that the laptop will be cool and quiet. The tasks which I do are: programming (C++, JAVA...) with Eclipse and other IDEs, UML programs, web developing (Eclipse, Dreamweaver, a bit of Photoshop...), databases... I not use CAD or similar.

As far as GPU, NVS 160M seems superior with low power consumption, and E6400 seems a bit small than M2400:

Code:

			NVS 160M	Quadro 370M
Chip Core		G98M		G98M?
Memory Type		GDDR3		GDDR3
Stream Processor	8		8
Core Speed		580 MHz		580 MHz
Memory Speed		700 MHz		400 MHz
Shader Speed		1450 Mhz	???
Max Bandwidth		11.2 GB/s	9.6GB/s
Memory Bus Width	64-bit		64-bit
Max Memory		256 MB		256MB
Current Consumption	12 W		15W

E6400 (mm): 335 x 238.3 x 25.4 - 31.0
M2400 (mm): 335 x 243.9 x 26.3 - 31.9

However, I like M2400 design (wavy lid) and I feel “secure” with Precision name because of my experience with Precision M20.

Can you help me to choose between M2400 and E6400?

Thank you!

 

If it helps you on your decision, the spec sheets says that the NVS160m uses DDR2 memory in the E6400 while the 160m in the E6500 uses DDR3 memory

I'm sorry. I've posted my message again.

Anybody can delete this thread?

Thank you

 

This information is a little inaccurate. I may be a completely late responding to this post but I have been considering between the m2400 and the e6400 and I was able to come up with this information regarding the graphics capabilities.

For the M2400 we have...

NVIDIA Quadro FX 360M

400 MHz, 16 - unified, DX10 | 600 MHz, 64 Bit

For the E6400 we have....

NVIDIA Quadro NVS 160M

Based on the GeForce 9300M GS but optimized for the stable business use (special drivers and bios). Supports PureVideo HD to help the CPU decode HD videos. (Memory speed: 400 MHz GDDR2, 700 MHz GDDR3)
580 MHz, 8 - unified, DX10 | 700 MHz, 64 Bit

Now, one important thing to remember is that the E6400 has the GDDR2 installed with it which runs at 400 MHz clock speed. It's the E6500 that gets the GDDR3 which runs at 700 MHz clock speed. However, the M2400 gets the GDDR2 running at 600 MHz MHz clock speed.

So we are talking about a very small margin of difference here. Basically the 360M has more memory speed but less core speed over the 160M. But not by much. Were are talking about 180 more MHz more for the M2400 graphics card over the E6400. Which you will barely notice unless you are a CAD draftsman or engineer.

To be honest after learning this. I still have no clue which one the choose. Basically whichever one comes out cheapest I guess. Oh well.
