Comparison: X200 and X201; displays, heat, battery life

#1 Post by wujstefan » Sun Sep 23, 2018 1:59 pm

Well this is something I have been looking for through lots and lots of forums and webpages, found literally nothing useful. And so the only way to check what was to be checked was to build those two units and test those things.

And so we have two specimens of X20x:
1. X200
- WXGA+ led-modded AFFS Hydis screen; modded with daylight kit from Monty
- 8gigs of DDR-3
- 240Gb SSD
- P8600 planar
2. X201
- WXGA LED
- 8 gigs of DDR-3
- 240Gb SSD
- i5-580m

Both completely cleaned, both with fresh Arctic MX-2 thermal grease, both running genuine NOS batteries.

Display lookup
My first lookup was to compare the displays. LED-mod from Monty actually reveals all the minor, non-visible flaws of the screen but offers far superior brightness and thus lower power consumption. Just take a glimpse:

Should I mention which of those is AFFS? :)

Temps
Another thing I wanted to test is running temperatures. I have tested with 15mins each, and took the HWInfo average as an output. X200 was not undervolted (yet!) And so:
1. Idle (ambient 23C)
- X200 44C
- X201 52C
2. Youtube video 720p, fan at "1"
- X200 53C
- X201 55C
3. Gaming, fan at "7"
- X200 68C
- X201 72C
4. Full load (Furmark + Orthos), fan at "7"
- X200 71C
- X201 82C
Honestly I was expecting to get way higher differencies between those two, as the X200 is said to run cool and X201 is said to overheat easily. I guess this is what a good thermal grease can do. The X201 feels warmer at the bottom when heavily used, but nothing bad really. I can easily use it at my lap. It's the difference between "cool" bottom of X200 when with no/light load and "warm" bottom doing the same with X201.

Battery life.
And this is what shocked me really. Well I think nobodys' gonna believe me without photos:
X201:

X200:

I have performed 3 tests to check this out. On cable graphics was set to full power, and on battery to power saver; CPU set to adaptive both cases. All are 15 minute test with average from HWinfo.
1. Idle (this is on the pic); wireless on, lowest brightness.
- X200 8,9W
- X201 7,8W
2. Youtube 720p video streaming; same 4/15 brightness notch
- X200 14,3W
- X201 14,4W
3. Gaming - tested with Starcraft 2; highest possible settings for both systems (X201 was allowed to use higher base video settings), same 6/15 brightness notch.
- X200 33W
- X201 31,2W

Thus the results were a bit surprising. I was really more than sure I will get less battery life and way bigger temps out of X201. Well, this got me surprised :) the temps are substantially lower especially under load with undervolting, and this also makes X200 run on battery a bit longer under load. However, Throttlestopping i5 also works wonders if you can live without turbo on battery ;)

The next step was to swap the AFFS to X201. Well, it's done now and under testing ;)

Hope this is a little bit useful to anyone. All in all there is no much battery life or heat difference in everyday use with those two :) OK, X201 runs hotter - or rather it does not run cool.

Good job and I found this interesting.

Yes the X201 should run hotter and the battery tests are a surprise but it maybe attributed to the screens.

Really looking forward to the results, screen backlighting (LED vs CCFL) can make a big difference.

My biggest disappointment with the x201 is that the cpu can't be undervolted. For some strange reason Intel didn't allow that for the first three generations of their i series processors.
Laptops after the 4:3 aspect ratio era are non-existent to me.

Both were LED, but I was expecting AFFS to consume way more power. Well I was wrong, the difference is the likes of 800-1000mW so nothing really bad.

This was a new technology and I guess those get pretty unstable with turbo boost mode. All you can is locking the multiplier, but this is simply not the same :)
