for CPU:
I bought the latest version based on the Broadwell architecture. The difference in performance to the older Intel Core i5-4200U and Intel Core i5-4210U Although only marginal, however, the integrated graphics unit was able to increase really strong. Apart from the 100Mhz per core clock more, but this helps to increase the frame rate by up to 10% in games like "League of Legends". Whoever buys the entry level model with Geforce 840M, can also be used in battery mode without Optimus technology that play at Full HD enjoy with maximum details (without antialiasing, shadows disabled), giving it even a little more battery life. This also applies to other games like Starcraft 2 or CS: GO.
for SSHD (8GB SSD cache):
however, my expectations was this solution but a good compromise to a SSD. Using Windows 8.1 64bit and UEFI Boot has as yet done a lot in recent years and who want a cheap model, will find the perfect solution. A few hints for retrofitting I would like to give:
It is possible to use the integrieten M.2 slot for SSD, as well as the existing 2.5 "drive bay. In the Pattern 2 SSD's I can only advise against fast models such as Samsung (not an option-ROM) XP941 / 951 / . Plextor M6e to buy, because these "clipped" by tying the M.2 Slots never achieve their maximum performance is the reason for PCIe 2.0 x2, connection (10Gb / s - 5 Gb / s per lane) and thus reach practically just not more than about 750MB / s. (Plextor M6e level).
Therefore, I recommend here an ordinary 2.5 "SSD your choice to build in, who really needs the space, yet can not do without an SSD, should resort to models such as Lite-On IT L8T-256L9G, which are also used by Acer. Stay tuned simply to the specification: SATA 6Gb / s SSD in M.2 2280 format.
To display:
Madness which quality and viewing angles an IPS panel guarantees. For me, no other technology is more used, whether PC monitor or mobile display. The illumination is uniform and has no errors in my model. Black levels are fine and 1920x1080 is the ideal resolution for relaxed carry on surfing and office work. One can beautifully display two Word pages side by side or even a PDF and simultaneous surfing is possible. (Windows key + Left / Right Arrow Arranges the windows 50% of the screen size)
Criticisms:
-Tastaturbeleuchtung:
This is by means of FN + F9 can be switched off, but not in stages adjustable, such as in the Lenovo Flex models. The illumination is not satisfactory in my opinion. There are more the edges of the illuminated chiclet keyboard, the red light of the LEDs does not seem really well through the label, here would have a higher voltage supply of the LED's can certainly still some rausholen on luminosity.
Who really needs also in the evening view of the keyboard, you should increase the screen brightness and so also gets sufficient Beleuchtungn on the keyboard;)
-SoftTouch Surface:
Panacea is unfortunately not yet. One criticism which I no longer had to install for years now comes in this model back into use. The entire palm rest and touchpad are matt coated and thus fat fingers immediately visible. Clean finger to help as well as little, as these are unavoidable and after only a few days use these almost impossible to remove, despite treatment with microfiber cloth. I do not want to have to use the swab after each use. Whoever does not is so from day one on Nachputzen which is over the months / years have no joy with the look.
-Battery Life:
is rather a joke when you reach considering the modern CPU's maximum TDP of 15W. I was able to test the same model with a Geforce GTX860M and have to say that you can be happy with the basic version, to be able to tease out an hour or two longer term. (Office mode with WiFi, screen brightness 70% -> 4h)
If you still have questions, you can feel free to leave them in the comments. I am willing to assist you in your buying decision.
