14" vs 15" T60 - a detailed comparison (pics)
Posted: Fri Jan 12, 2007 1:26 pm
I bought a T60 from the marketplace for my friend (thanks to beavo451 for his awesome price), and I had a couple of days when I was setting up the laptop to compare it with my 15" T60. This post is simply a summary of my observations comparing these identically set-up laptops on windows XP although some points have been discussed before here.
1. Build and Size:
The 14" T60 is one sturdy beast - it is the most solid thinkpad I have seen. I'll go ahead and say that it seems better than my 15" (which is amazing in itself). Weight seems more evenly distributed and the laptop is a fantastic size to work with on your lap. I find the 15" a bit big to use on my lap (I use a X31 for that
), but the 14" is perfect. The front "edge" of the 14" (where the LCD latches to the base) and the front corners are designed slightly different (with a more squarish finish) than the 15". There was NO flex whatsover on the 14" (even on the flap cover area in the palmrest and above the ultrabay) while there is a small flex (nothing alarming, very very minor and I pickily do notice them) in these areas on my 15". Keyboards on the machines were identical, though a tad better on the 14" which appeared to be more solid with a better travel than my 15". Both were NMB ones I guess (I could see the blue riser under the keycaps, which I remember were told as NMB on the forum somtime back).
2. LCD quality
This is a no brainer. 15" flexview beats 14" (and any other laptop display for that matter) hands down, legs down. Both laptops have a X1400 GPU @ 1400*1050. Colors look a bit dull and the viewing angles are poor on the 14". There is quite a bit of ghosting and the contrast is not so great either. I happen to have the video of the movie "Before Sunrise" (it has some fantastic sunlight lit european streets) on two portable drives and I ran it on both laptops simultaneously (without sound though
) and the difference is striking - I'll take some pictures with both and post them sometime soon). People in doubt, please get a 15" if you dont mind the size.
3. Battery life
With both laptops having 6-cell batteries, display down to minimum and wifi on (and set to max battery in access connections on both) and opera 9.1 running 5 tabs (identical on both machines), I get 3:05 on the 15" and about 3:30 hours on the 14"(both batteries are practically new, with the 15" having just 2 cycles on it and the 14" ~30 cycles). I did not drain the batteries fully though - stopped the "experiment" at around 60% on both latops.
4. Heat and Noise
There have been many posts in this forum saying that T60 is noisy and the fan is on for quite a while etc. Before I start, I wouldlike to say that I am quite sensitive to system noise and my room is essentially noiseless. To compare noise levels between the 14" and the 15" models, I set both of them to max. performance and ran identical matlab code on both. The program is a complex piece of hand-optimized code that is CPU and memory intensive and runs for about 30 minutes on full steam (with enough graphical output and quite a lot of file i/o - good enough for real world testing purpsoses). The spec of machines were slightly different (15" with 2 GHz Core duo + 2 GB RAM + a 7200 RPM HDD and 14" with 1.83 GHz Core duo + 1.5 GB of RAM + 5400 RPM HDD).
Not surprisingly, the 15" was more noisy than the 14" maninly due to the difference in the HDD. Fan noise was minimal to non-existent on both laptops. The 7200 rpm Hitachi is noisy even at quiet setting. Because of the nature of the code, fans were on in both machines for atleast ~20 mins and temperatures on the 15" was a bit higher (57C with fan at ~4500-4700 rpm, idles at 39-42 C with fan off or at ~3000 rpm for a short duration with adaptive setting) compared to the 14" (55C at ~4300-4600 rpm, idles at 39-42C with fan off or at ~3000 rpm for a short duration with adaptive setting). The 15" finished the simulation faster than the 14". I used TP control to monitor the fan speeds and the temperatures and did not use any manual settings.
Conclusion:
If they offer flexview on 14" (which is not going to happen
), I will trade my T60!
NB: I'll be having the 14" till monday - if anyone has questions I'd be happy to answer.
