X1 Carbon 2014 vs T440s

[josephaedrus]

Hi,

Tried this on the X1 thread but with little interest so thought I'd ask previous T410 owners here. I have a faithful old T410s which had taken to freezing roughly every two hours. Almost certainly a heat problem but it's probably time for a replacement anyway.

Tempted by the 2014 Carbon. But I'm hesitating over the power and things like the 8MB Ram limit which seemed plenty 4 years ago on my 410s but now feels a bit limited.

This will be my main work machine on which I will want to do some programming, run a virtual machine occasionally but also do a little amateur film editing and music (cubase).

Does anyone have an opinion on whether I should stick to a more traditional work horse like the 440s or whether ultra-portables are now ready for this level of work?

Many thanks

I am of the opinion that ultraportables are thermally stressed by workstation use. With GM as an example of industrial ethics that may not be as unique as we would hope, we don't really know whether Lenovo and other manufacturers have really qualified these machines for such use, or consider the loss rate "acceptable."

Given the thermal problems with some prior Lenovo laptops, they may think more like GM than we would wish.

What was acceptable to GM is not acceptable to the user.

You might be interested in knowing that neither of those two laptops will be any faster than your T410s by nature of their ULV processors.
Their maximum turbo boost is comparable to your old processor using no boost- Haswell isn't distinguishable from Arrandale/Sandy Bridge/Ivy Bridge apart from power consumption; it performs very much the same at the same frequencies.

The T440p is the only one that will provide an upgrade in CPU power, but it's a chunkier machine.

What I'd do is try TPFanControl and use ThrottleStop's logging feature to see what's going on thermally.
You can also try reseating the heatsink assembly and new thermal paste- worst case is a new motherboard; it'd be far less expensive than either of those machines, and you'd still have the better ThinkPad (with buttons, keyboard, and 16:10 screen).

Yeah that's not making much sense to me:

Yes benchmarks doesn't tell the whole picture but faster everything else definitely makes a difference on the whole.

This is the basic CPU for the T440s vs higher end for the T410s.

As for me I have a T410si too and looking to upgrade to the T440s. I included the T410si CPU (Core i3) because that's what I have. I don't need super performance but definitely getting a little sluggish for my usage these days.

I am buying online this weekend so hopefully it comes soon and looking pretty!
