    Thinkpad X230, X240 or another one?

    Good evening dear ThinkPad community,

    I will start studying again for 1 year next summer and am thinking of buying a new (and possibly used) notebook, not only for studying but also for work.

    At the moment I have a used T410, with which I am quite satisfied, but it is slowly no longer a) too heavy b) battery

    What should the new device be good at?

    a) long battery life (professional and private)
    b) relatively light and compact
    c) robust case (Thinkpad?)

    What is done with the device:

    a) Office (a lot of Excel), internet, e-mail

    Now perhaps the most important. Since I have to pay quite a bit of fees for studying, I don't want to spend that much. That means 700 € is the maximum.

    At ok1.de I would even get a new X240 for the price, but maybe you have more tips etc. for me.

    Thank you and have a nice rest of the weekend!

    A model from the X-series is ideal for you, because light and compact are important to you. a) and c) is also fulfilled for the X series.
    Now you have to think about whether you like the touchpad on the X240, if so, take it, otherwise get an X230i with a student discount even has a real mobile Ivy Bridge CPU and no ULV like the X240, although I have to say that the X240 probably consume less power becomes.
    But with a 9 cell battery in the X230i you will easily be able to work 10 hours.
    As far as the speed of the CPUs is concerned, both have roughly the same power.

    The X230i is unfortunately already sold out !?

    Thank's for the Tipps! The X230 costs almost as much on eBay as the X240 on ok1.de ?! Then I'll probably take the newer one, because I need the longer runtime more than power.

    There are a few basic differences between the X230 and the X240.
    The X230 is still a subnotebook, i.e. it has a fully-fledged mobile CPU, the RAM can be upgraded to 16GB, etc.
    The X240 is an ultrabook with soldered ram (limited to max 8GB SINGLE CHANNEL!), A ULV CPU etc.

    It depends on how much power you need.
    But with both models I would make sure that you buy one with an IPS display!

    Oh yes, if it doesn't necessarily have to be a new Thinkpad, then you can also look for a used X230 here in the forum

    Well, I don't want to spend more than 700 € because there won't be an IPS display (not even with used ones)

    not a bad offer at all.

    The only question is what the IPS conversion costs and, if necessary, the conversion to the backlit keyboard (would be the main reason for me to prefer the X230 to the X220 ^^)

    So the display apparently costs € 100 + installation and then there is the illuminated keyboard. I still have a little time to think about it

    @Chrischan,
    there is no RAM soldered on the X240. It's also just an ultrabook when it comes with a touchscreen. Otherwise it is a completely normal subnotebook with ULV CPUs. "Subnotebook" does not mean that it has to have 37W CPUs. Long before ultrabooks existed, there were subnotebooks with ULV and LV CPUs. Subnotes are only notebooks <13/14 ".

    again about the x240 (would be my favorite because it is the newer device): Do you notice the difference between dual and single-channel RAM?

    Doesn't matter with the CPU anyway

    The difference should be noticed before everyone, not exclusively, in games. However, the HD 4400 is more powerful than the HD 4000 in the X230 anyway, and in terms of the GPU, both should be roughly on par.

    Even if it's not a panacea, a first look at the benchmark list from cpu benchmark gives me at least a hook where to classify it. The touchscreen for ultrabooks has only been introduced by Intel since CES2013 as a "prerequisite" for ultrabooks, so it is not surprising that not everyone knows this. The Ultrabook sticker sticks to (older) models without a touchscreen . In its review of the X240, Notebookcheck reports that, despite the information, the maximum clock rate (here with the i7) is not reached under full load. On the contrary, the CPU even clocks down after a short time ... whether this is the case across the board with all models and other i7 CPUs of the same design is difficult to say ^^.

    hm ... that doesn't exactly make it easier for me. I didn't think the search would be that complicated

    Yep, the student x240 with the i3 is sometimes slower than a 5 year old X200 ...
    One should choose a fair comparison: The i3-4010U is the slowest CPU in the X240, and yes, it is slightly slower than the fastest CPU in the X200 (T9550). However, not a fair comparison, then you should compare the i7-4600U against the T9550, and the X240 wins again. If you compare the i3-4010U with the P8600, a CPU that is very often built into the X200 (and also built into your X200 as it looks), the i3-4010U is again faster. And that's not even the slowest CPU in the X200 (there is still the P8400, and the CPUs built into the X200s are a good deal slower again).

    If you compare unfairly you can also say that the X200 is faster than an X220 (which still has full-voltage CPUs), because the T9550 is faster than an i3-2310M ... Quite a pointless comparison.

    Don't let yourself be unsettled: Even the weakest X240 is very good enough for the use you specified ("a) Office (a lot of Excel), Internet, e-mail").

    I wouldn't take the weakest X240 because of the missing IPS display.

    @ibmthink:

    You can turn it around and gloss over it as you want, the x240 is simply lame compared to its predecessors. Of course, it is sufficient for Office, but an X60 for 100 € would do the same.
