+++X250, why SINGLE channel memory?!! Why?!!!!!!!!

2015-02-01, 16:34 PM

Lenovo, if you had to max out the memory at 8Gb, ok, I could live with it.  But, what I don't get is

 

Why sinlge slot/single channel?  Single channel is 1/2 speed of dual channels in theory.  Why can't you make it two slots/dual channels so that we don't get the max RAM but at least we get the memory speed???!!!

 

Memory is the 2nd most important thing in laptop in terms of speed.  Did our designer graduate from high school??

 

Why I am seeing a trend that old IBM desgin and quality are going down to the toilet year after year?

 

Disappointment after another.  I have put high hope on x250 after the terrible x240. This is what we got??!!!   I have given up with Lenovo, going with HP now, at least they still use dual channel memory.

If it has to be single channel,  give us 16GB max memory to run VMs.   If we have to pick one out of two, please at least give us a good one.

My almost 3 years old X230 is using i5-3320M CPU (middel range cpu),  CPU mark score is 4013

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-3320M+%40+2.60GHz 

My X230 has dual channel 16GB Max memory.

 

3 years later, X250 is using a U(Ultrabook) CPU

at i5-5200U (middle range cpu), it is CPU mark score is 3741.

http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-5200U+%40+2.20GHz 

 

You feel the irony?

Are we moving forward?

WHY would you spend a big chunk of your money to "upgrade" to a machine which is less powerful and less RAM speed?!!!

 

All Lenovo want to do is hoping you DO NOT know the facts!

 

All we can do is a) never upgrade b) dump Lenovo and go to another vendor.

Hello,

keep in mind that the overall performance improvement of dual channel memory compared to single channel memory is not twice as high. In fact, mainly the GPU performance of the Intel GPU improves because it uses RAM as video memory.

Don't forget that the Core i5-3320M has a thermal design power of 35W, while the i5-5200U only has a thermal design power of 15W.

Yes, we are.

  • The build quality of the X250 is far better than the X230 build quality
  • The energy efficiency of the CPU is much higher, resulting in longer battery life.
  • The Full HD IPS screen of the X250 is a huge improvement compared to the abysmal 1366x768 IPS screen of the X230

Kind regards,

 

Felix

IMO, having two slots of RAM is more important; dual-channel is an added benefit.

Frankly, with the design of the X250, it's just a glorified Ultrabook instead of a full-power ultraportable like the X series used to be. We could have just had an X230 refresh with the added build quality, newer chips, and FHD, but it didn't happen.

W520: 2960XM, Q2000M @ 1091/1380, 32GB RAM, 500GB&750GB HDD & 500GB SSD, FHD&MB168B+
X61T: L7500, 4GB RAM, 500GB HDD, XGA screen, Ultrabase
W550s: 5600U, K620M at 1164/1281, 16GB RAM, 512GB SSD, 3K touchscreen
X200s: SL9400, 6GB RAM, 64GB SD card, WXGA+ screen

"Don't forget that the Core i5-3320M has a thermal design power of 35W, while the i5-5200U only has a thermal design power of 15W."

Yes, it is a fact but I don't agree on this factor.  X serial has been a full powered ultraportable business machine, it has never been in ultrabook category until now. If I need an ultrabook, I would go for Apple or Samsung, at least they look better and more stylish.

Most of time even when you are traveling, you will probably find a power source in a fastfood restaurant, a cafe, hotel room, airport or office and you will be plugged in most of time in reality, assuming you do not use your laptop when you are driving.

My X230 could go for about 8 hours when it was new, that is good enough. I personally don't want to sacrifice computing power for battery life, which it can be easily remedied by adding an extra battery and accessing a wall outlet.   I wanted a full powered ultra-portable business class  computer which X serial used to be NOT an ultrabook or a tablet.

Thank you for your reply anyways.

"The Full HD IPS screen of the X250 is a huge improvement compared to the abysmal 1366x768 IPS screen of the X230"

X230's 1366x768 screen is already HD screen, not Full HD, but HD. I don't really get it, why do we need to have full HD or 4K screen on Laptop or cell phone nowadays?

Anybody has problem in seeing a screen at 720HD for your normal life computing activies?
Are we all working the art design industry?

 

I seriously doubt that those who so much care about 1080P or 4K screen resolution are the intended major customers for Lenovo because ThinkPad has been a standard for rugged full powered business class work horse machine for decades, never primarily for looking good.  Those people would be much happier if they go for Apple or Samsung for that requirement.   

 

It is really sad to see a used-to-be great ultraportable power horse turning to an ultrabook just to "follow" Apple, by rapily loosing most of good characteristics it had been known for. 

 

What Lenovo didn't realize was, no matter how close Lenovo manage to look like Apple, those who buy Apple will probably never buy Lenovo IMHO.

hi flatiger,

 

I, for one, would pay extra for a better screen resolution. But, granted, that is more of a nice to have.

 

A must have, for the business in which we are, is full 16GB of RAM. Whether they are dual channel or single channel, maybe not that important for us. Probably because of the edge dual channel gives, it is better.

 

But, having only 8GB has been a deal breaker for us. Right now, i'm running in an HP Elitebook 820, with 16GB and a full power processor, but with screen resolution 1366 x 768 which is far from ideal in a world where apple ultra portables get super-fine resolution, and with a subpar performance touch-styk.

Absolutely.

 

1366x768 resolution is too low, and hampers productivity. Try Visual Studio and Eclipse (or any IDE) that divides the screen into subpanels. Each panel is only able to display a painfully small amount of information. You end up having to do a lot of scrolling. Or a photo or graphics editor, where the floating toolbox and options panels may cover a significant part of the document. Even Microsoft Office, where you have to collapse the ribbon and page preview panels because they take up too much valuable screen space. Even my 10 year old IBM Thinkpad G41 had a 1400x1050 screen.

Agree with Richard.
I use Excel and python editors, and in many cases I want to see results side by side. Or you may want to have outlook open on the side. A small resolution screen requires jiggling multiple windows from back to front
Even if only working in Excel, the abiliy to see many rows, and see numerical results and graphics that show those, is very important
