i5 4200U vs i7 4500U in photoshop
Oct 23, 2013

I may have found perfect laptop for editing photos...
Im on the road 99% of the time and while i dont need super portability and would prefer 15" at least
The screen and colors of lenovo yoga 2 are just astonishing... I mean you have to see it personaly.
Its probably if not the most briliant screen ive ever seen period, on the laptop for sure... On par or better then retina macbooks or ipads

But, is the i5 or i7 enough to work with 200-500mb tiffs applying layers and filter etc enough?? It needs to be pretty snappy otherwise usage will get frustrating for me...
Is there any real world difference between the 2 processors? I mean i can wait sec or 2 extra to process applying of something but if its too much...
I had macbook pro 13" second gen i5 2.3 couple years ago ( with 8gb ram and ssd) and it was barely acceptable for me speed wise. Maybe haswells are much better ?
Thanks

I wish someone would chime in. I am in the same boat. And saw the Yoga 2 also.

I just saw some benchmark at one of the sites after some google research...
In benchmark performance is pretty sad compared to even older desktop cpus but we need user real life report

Yoga 2 scaling
In reply to akjos, Oct 25, 2013

I also have been looking info re the Lenovo Yoga 2 and it's amazing 3200x1800 screen.

However, after reading the thread in this forum re Ultra High Def laptops, the scaling issue has me somewhat skeptical that this thing will work for me in the real world.

.

I've also read that there are issues with colors on the Yoga 2 screen - something to do with yellows or oranges.  And, I've read similar about the new Samsung ATIV Book 9 with its' 3200x1800 screen - where colors in battery mode are different (& wrong) from colors in AC powered mode.

I think it's a bit early to jump in on these QHD+ panels so I've resigned myself to finding a laptop with a more standard 1920x1080 IPS panel.

Neither of those processors are very powerful by today's standards at about 1/3 of the performance of top laptop processors. If you want good performance I would look for a laptop that has an i7-3740QM or i7-3840QM.

I believe i have read the thread you linked...
Jury is still out i guess :/
Ive also heard rumored yellow / orange tones being way off...
Idk i looked at a LOT of my old images on yoga 2 in bb, and these for example in partucular looked just about identical to my older calibrated samsung 22 " ( non ips) i have at home so idk what is all the fuss about...

Ive really been looking for 4th get macbook air. But no, apple decided to drop a ball again. I dont need such ridiculous resolution on 13" laptop like retina or yoga 2
Simple 1920x 1080 would be great and im really disappointed that apple didnt come thru...
Plus all air models had very obvious pink/ magenta/ red tint to their screens ( last 2, didnt check the 4th one in person yet) . It might calibrate ok but i prefer as good colors as possible out of the box for this kind of $$
I might have to get 13" macbook pro loaded and bite my lip when i process my order... I love yoga 2 but im not paying 1500 for nightmare 8.1 ( lenovo site with i7 and 8gb ram, - bb is sold out at 1199 ) when there are seemingly better options in this price range.

Yes im aware of that... But it seems impossible to get powerfull enough laptop with not great but decent screen...i had asus ROG 2 years ago loaded and it was awesome , except the screen. New ones are better ( matte) but still look horrible conpared to macs or top 13" underpowered ultrabooks.
And if i got 2000" 17" 10 lbs beast ( which i wouldnt mind really) it better have great video card for gaming. I know i can get pro or business type laptop with excellent screen but im not interested in ati fire or nvidia quattro
I really dont want to spend 2000-2500 on laptop again being the technology obsoletes so riduculously fast.
I wish i could build bad a$$ pc again for 500-800$ but unfortunaltely i need a laptop as a road warrior :/

I might have to make one more trip to bb when i actually get home next week and set the yoga to 1080p and see how all the fonts and pixel and overall looks comes out.
I dont need such crazy resolution so will see. But i LOVE the colors.
I might even bring and install a photoshop just to see how good or bad the interface scaling looks lol

i5-4200U is a dual core 1.6Ghz, 4th Gen processor with hyperthreading and 3MB of cache.

i7-4500U is a dual core 1.8Ghz, 4th Gen processor with hyperthreading and 4MB of cache.

One would expect about a 13% difference between the two based purely on clock speed, and maybe an additional 3% in certain apps based on cache.   Since they are the same family and same architecture, you really can just go off clock speed.

They are going to be struggling  with heavy photoshop work, but they will handle it.

Keep in mind that you may benefit from higher resolution in a smaller screen. However screen brightness should not be an issue. Most screens are too bright for image editing and have a maximum brightness of 300 cd/m2. Somewhere around 120 cd/m2 is much more suitable for image editing.

I just got a i5 yoga 2 pro with 4GB RAM and 128GM HD and am loving it.  I haven't done much in Photoshop, but  I have render some things in Fusion (a video compositing program like After Effects) and it rocks!  It's actually renders the frame faster than my desktop which is an older i7 920 CPU.  But because it only has 4 cores and my desktop has 8 cores.  My desktop can render more frames at a time so it gets the project done faster.  I've tried to over load it by running a bunch of programs to max out the RAM.  Can't do it.  It's can somehow manage all those apps open and give you good performance with whatever your doing.  As I am typing this, I've got a really complete project in fusion rendering in the background and I see no preforms loss.  Now I just loaded Lightroom...and do some developing on a photo.  Still very good performance.   I will probable keep this i5, but I want the i7 with 8GB RAM and 256 Hard drive.

- Peace
