Dell Precision M4700 and M6700 - Preliminary Info

Might you add the chief differences between the IPS Premiere Display and the 3D Vision Pro, i.e. pros and cons.

 

i remember, many people had problems with M4600 IPS displays related to Screen Corner Tint. Has it been resolved with the new M4700?

 

So the new M4700 is about 1200$ more than a comparable W530... I assume that's normal for new products, how long does it usually takes for a price-drop on new Dell laptop?

EDIT: nevermind, Dell Canada prices are through the roof!

 

Make sure you are comparing the same configs. Lenovo is bad about burying some specs to make things appear cheaper.

I went through on the US Small Business stores and spec'd out the same config for an M4700 and Lenovo W530. Where Lenovo has lower specs like the 1 year send to depot warranty, I raised it to the minimum 3 yr next business day that is the Dell minimum.

I configured them with the 3720QM, K2000M, 1TB HDD, 1920x1080 screen, Intel 6300 wifi, 4gb ram, and 9 cell battery.

The Lenovo is 2054.45 and the Dell is 2042.00.

The only components that could cause more of a price difference as the IPS panel and 3920XM. The IPS panel is $399 more. The 3920XM is $150 more.

The 3920XM can't really be argued. Lenovo is selling it $150 cheaper than Dell.

The IPS panel can be argued.

Even though the Lenovo has a panel that covers a 95% color gamut, there is a lot that is unknown. I can't find any information on the Lenovo site or in their manuals to say what color gamut they are talking about. 95% of sRGB, AdobeRGB, and NTSC would each be very different. I worry about how ambiguous Lenovo is about this. The panel would also be a 6 bit TN panel which means 64 shades of red, green, and blue with the rest of the 256 colors simulated through dithering or rapid color switching. Max brightness is 270 nits.

The IPS panel is 10 bit and Dell is very forthcoming about it covering 100% of AdobeRGB and NTSC. Since it is 10 bits, you get 1024 shades of red green and blue. No dithering, no local switching. No false colors on gradients. You also get 300 nits of brightness.

Anyhow, worst case scenario in the US would be $549 difference for IPS and 3920XM. Then again, you would be getting a much better display. Whether the CPU would throttle in the Lenovo, is an unknown to me. Will have to read some early reviews.

If you add Solid State drives into the mix, Lenovo gets more expensive in a hurry. Lenovo's drive options overall are VERY limited.

 

My bad, the US price seems on par, it's the Canadian website that is out of line, but that's probably because they haven't updated the launch price yet. In any case, the DELL is the superior laptop in my mind!

 

Based on the noteboookcheck tests, it is 95% of Adobe RGB:

 

Do you know anywhere I can get a similar comparison for Lenovo S30 vs whatever Dell might offer as competition? T3600 or T5600?

 

Looks like the are still using the AUO panel with the B+RG backlighting.

The notebookcheck tests were not exactly flattering. The said that in the Yellow/Orange section that it does not cover sRGB. This gets a lot worse for aRGB and NTSC. Overall though, it does have a wider color gamut than the standard FHD screen in the M4600. The IPS screen is covering 109% of NTSC, which is wider than Adobe RGB.

They also said that the W520 colors were off and that you had to calibrate it to get them to look natural.

Not sure if this is all a trade off of not using full RGBLED backlighting.

All of that said, I am left to wonder about some of the measurements Notebookcheck is getting. I also have measured the M6600 with the Spyder 3 Elite and got better results than they did in their M6600 review. You would think our measurements would have been closer.

 

Lenovo still seems to be much cheaper. I'have compared two similar entry configurations:

i7-3720QM
1920x1080 (IPS for m4700)
8GB RAM
500GB HDD
NVIDIA K1000M
9-cell
Intel Centrino Ultimate-N 6300
Bluetooth, fingerprint reader

Lenovo W530 via B&N: $1,329
Dell M4700: $2,301 (Dell rep offered a better price of about $2,100 over the phone).

Basically, it is $1,000 difference with a similar spec yet a better ISP display.

 

I agree, you have to calibrate W520 to get a decent color representation. After that, it looks much better than all my other WLED displays. Perhaps, it is not as good as a true IPS screen, but you get an extra bonus of Optimus and a longer battery life.
