3rd Gen intel Core i7 (Lenovo Helix) VS. 4th Gen intel Core i5 (Surface Pro 2)

I am comparing two tablets

Lenovo Thinkpad Helix
VS.
Microsoft Surface Pro 2


for the processor, what is the technical and practical difference between:


3rd Generation Intel Core i7-3667U Processor( 2.00GHz 1600MHz 4MB)


and,
4th generation Intel Core i5 (I don't know cash and speed)

and what is the haswell



and what you recommend Lenovo Thinkpad Helix or Microsoft Surface Pro 2


Thank you

I would recommend you have a look at this website:

http://www.cpubenchmark.net/

It lists benchmarks for all CPUs available on the market, allowing you to compare like for like.

Haswell is 4th generation Core-i processors. More info on these are available here:

The Thinkpad Helix is a far nicer system => MUCH better keyboard; superb versatility; great battery life; etc.

Hello garycase,

have you ever used the helix for a while, or just from the first glance?

I've seen one and had a chance to use it for a few minutes -- I was very impressed.

I'm retired -- but if I was still traveling, I'd absolutely have one !!

I've also seen the Surface Pro ... it's also very nice => but the difference in the keyboards is like night and day -- no contest at all.

Comparing the 2 side by side throwing price out the window the Helix has far better everything.  But price is always a consideration and the Helix costs nearly $1000 more baseline Surface starts at $899 and the Helix with the i7 you mentioned starts at 1873.52.  It's really up to you but unless you're doing a lot of options the Surface is going to save you money as it's looking like it will be a $1799 max price on the Surface with all options.

Here is the CPU that is coming with the Surface Pro 2: Core i5-4200U

Here is a comparison between the 2 CPUs:
http://www.cpu-world.com/Compare/863/Intel_Core_i5_Mobile_i5-4200U_vs_Intel_Core_i7_Mobile_i7-3667U.html

Another thing to consider is size you get a 10" screen with the Surface vs. an 11.6" screen with the Helix.

Dear all,

Please neglect the price in your comparison,

I want to know: (and the comparison based on data from the manufacturers:

GHz: how much each one, and who is better (I see in Helix datasheet that it is 2 while Mr. Kadafitcd's site says it is 3.2) ??

Clock time: who is better
Cash in Mb: who is higher
Performance:


also,

what is the difference between haswell and Ivy bridge?

and what is the difference between 3rd and 4th generation of intel processers?

Thank you

The Surface Pro 2 uses a Core i5-4200U running  at 1.6GHz.    This CPU scores 3384 on PassMark (an excellent measure of CPU "horsepower").

It's a Haswell CPU ... 22nm lithography and the newest generation of Intel's chips.   But an Ivy Bridge CPU is also a 22nm CPU, and except for a slightly slower embedded graphics engine there's very litter difference in performance -- most people would never notice the difference.

The Thinkpad Helix can be purchased with two different CPU's (both are Ivy Bridge units):

... a Core i5-3427U  => this scores 3613 on PassMark
... a Core i7-3667U  => this scores 4058 on PassMark

Both outperform the Surface Pro by a modest amount.

They're both excellent units.    The Helix is clearly the nicer of the two -- if you get a chance to see/feel/touch one there's no doubt you'll agree.    If cost isn't a significant factor, it's a very easy choice.

Hello garycase,


To make it simple,

I am comparing this Helix model:
http://shop.lenovo.com/us/en/tablets/thinkpad/thinkpad-helix/?sb=:00000025:000036CE:

by the surface pro 2,



The intended use is for Construction Engineering Software, and Rendering,

I wanted scientific reasons to differentiate, and I got it for the CPU, but there are some other concerns,


1. What is the impact of the CPU for helix over surface, is it the multitasking, or software installation, or speed or what?


2. surface has 512GB ssd, where Helix is 256GB.

3. surface has 10 hours of battery(4cells), but the helix (3cells) ???

4. surface has Office 2013 & Skype Calling.

5. Microsoft said that they will unveil new accessories next year, helix not ?

6. other things like Graphics ??

6. the Wi-Fi and Bluetooth ??


For the helix,

a. what is the mobile broadband

b. for what is the SIM port for, can I receive calls, and SMSs

c. I want to use a monitor and normal keyboard and mouse, can I?

d. Is there any new release for the helix, will come in the near future, so I can wait and have more?



please don't consider the money in your comparison.


Thank you

Your link doesn't work, so I don't know which model you're looking at.   There are 3 CPU choices -- I assume you're looking at the i7-3667U unit with the 256GB SSD ... is that correct?

Assuming so ... here are a few differences between that and the CPU used in the Surface Pro 2:

=>  Graphics:  HD 4000 (Helix) vs. HD4400 (Surface)
      Performance differences depend a lot of exactly what's being done.   There's no real difference in 2D performance, but the 3D performance is always better on the 4400.       Futuremark 3DMark06 scores are 5120 for the 4000, 5691 for the 4400.


r.e. your questions:

1. What is the impact of the CPU for helix over surface, is it the multitasking, or software installation, or speed or what?  ==>  Very little.   The i7 in the Helix has 20% more "horsepower" than the Surface; but the embedded graphics in the Surface Pro's CPU is ~ 10% better in 3D operations.

2. surface has 512GB ssd, where Helix is 256GB.  ==>  Yes, this is simply a fact.   The surface has more native store.

3. surface has 10 hours of battery(4cells), but the helix (3cells) ???  ==>  The Helix is rated for 6 hours with just the tablet (detached from its keyboard); or 10 hours when attached (the keyboard has an additional battery)

4. surface has Office 2013 & Skype Calling.  ==>  Any software function can be done identically on both ... they're simply Windows 8 computers.

5. Microsoft said that they will unveil new accessories next year, helix not ?   ==> Who knows what this may mean.    Remember, they're both just Windows 8 computers.

6. other things like Graphics ??  ==>  Already noted -- HD4000 vs. HD4400

6. the Wi-Fi and Bluetooth ??   ==> Both have both.

As I noted earlier, both are excellent machines.   My preference is absolutely for the Helix; but the extra storage and slightly better graphics on the Surface may influence your choice.   If you're strictly a touch user, it probably doesn't matter;  if you use a keyboard, I can't imagine anyone preferring the Surface keyboard over the superb Lenovo keyboard.

and what for the questions a, b, c, d

Gary CaseRetiredCommented:
a. what is the mobile broadband => embedded 3G support

b. for what is the SIM port for, can I receive calls, and SMSs => For your wireless provider ... but it's not a phone.

c. I want to use a monitor and normal keyboard and mouse, can I? => Yes, it's got a mini-display port and a USB port you can use for a keyboard/mouse

d. Is there any new release for the helix, will come in the near future, so I can wait and have more?  ==>  I'm sure there are newer versions coming, but I have no insight into what or when.

Hello again

Ok. I got the answer, but I have several questions more.


1. I have an external HDD that I installed win8 OS. , does helix support booting from USB ??


2. can I format the helix and install other versions of OS??


3. in case after a period of time I want to throw the helix away, can I dismantle the SSD from inside and put another one, to keep my data from disclosure?


4. does Lenovo have a blog or something that I can obtain news for what is coming, and what is expecting??

5. is there any other tablet in the world that has specs higher than helix ??

Thank you
