X200s and Celeron M??

#1 Post by Thinkpad4by3 » Tue Oct 02, 2018 1:22 pm

The X200s comes with a Celeron M 723? Isn't that a P-M based chip? Why would it be in a C2D Penryn machine? Isn't it basically the equivalent of a high spec Tutalin core? Anyone have experience with it? Lastly, why would Lenovo put such junk in the X200s(the higher end machine?)

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

Since the market is pretty easy to get these machines you just leave these alone. The most popular model is the P8700 and thats a Penryn.

Lenovo seemed to do a fair few poverty spec models so this isnt unusual. But since the price btw. a mid to high spec version is minimal I just skip these.

I had an R500 with a 2.0 ghz Celeron, it was as slow as Pentium M laptop. Just put in a T9400 and gg.

Pretty sure the x200 series all has a soldered cpu. So you need to change boards.

Cause some customers want the lowest price, so using a Celeron helps shave money off the price.

There are some instances where you want a rugged and enterprise level machine but you only need minimum specs as your workload... is in the cloud.

Many companies run virtualised desktops. So you can get by with a laptop with a slow cpu and 4gb ram.

You just need wireless and/or a nic.

The Celeron M 723 is a single-core Penryn deprived of features like VT-x and Speedstep (!!).

If you've ever used a Core Solo, that's pretty much it. Or you can actually simulate one by disabling multiprocessing in BIOS, then reducing the max CPU speed to 1.2GHz. Or just try any single-core Atom netbook. :lol:

A lot of machines of this age just isnt worth buying.

Even a medium spec x200 like my old one with say a P8700 4Gb 120gb ssd Intel 5300 is a baseline machine.

ie. dont expect it to burn thru your workload.
