Sony Vaio Z2: Everything is Peripheral
by Dustin Sklavos on February 13, 2012 12:55 AM ESTApplication and Futuremark Performance
Sony's decision to use a full-wattage Intel Core i7 dual-core mobile processor in the VAIO Z2 instead of the 17W CPUs notebooks with these kinds of dimensions usually enjoy means you can expect the Z2 to perform consistently at the top of the heap where application performance is concerned. Add the AMD Radeon HD 6650M in the Power Media Dock to the equation and suddenly you'll also see the Z2 go on a tear in Futuremark's tests. Note that we're focusing on the ultraportable market here, so there are certainly faster laptops around; they're just not available in a sub-14" form factor.
Or at least it should. In PCMark 7 we can see from the Computation score that the Z2 is clearly running the HD 6650M properly (Computation employs Intel's Quick Sync), but the 6650M seems to have a deleterious effect on scores across the board. I have to wonder if PCMark 7 doesn't just outright favor Intel's integrated graphics: notice how every other system with a dedicated GPU clusters at the bottom of most of the charts.
PCMark Vantage proves to be a little more even-handed and scores line up where they ought to be, with the HD 6650M offering an improvement to the Z2's user experience.
Unlike PCMark 7, our application tests reveal no difference in performance between having the Radeon on hand or just using the integrated graphics. These tests are purely CPU bound.
Predictably, the 3DMarks enjoy a substantial boost in performance from switching over to the dedicated AMD Radeon HD 6650M. Unlike the Radeon HD 6470M in Sony's VAIO SB, the 6650M is a definite and notable improvement on Intel's integrated graphics.

I've owned the Z2 for about 6 months now (so I am biased ;) ). I didnt realize the hinge design was a problem before reading this review :). I have never experienced any problems with the computer sliding about during use or finding the sweet spot for screen angle. The incline is not that dramatic.I agree that the keyboard is not perfect (it was better on the previous Z) with the shallow travel, but in my opinion it is not bad and it didnt take long to get used to.
Regarding graphics performance it is at least partially a driver problem. Sony is unfortunately poor at releasing updated drivers (I have sent a complaint/request about this to Sony Norway), but there are community drivers that work well. I'm using the AMD 11.12 drivers from here:
http://forum.notebookreview.com/sony/636724-univer...
It actually makes BF3 playable on the laptop. It is also possible to overclock the GPU and control the GPU fan using Sapphire Trixx (I understand that you dont review a unit with community drivers and overclocked GPU, but the information may be useful for other potential owners).
Regarding fan noise and temps it is noisy when playing games at full cpu load and using the Intel IGP, but I dont find it particularly noisier than other laptops at load I use (HP 8440p at work, Alienware m15x etc). During normal use (web browsing, watching HD videos etc) it is very quiet. One can also select thermal profiles in Vaio Control Center (silent/balanced/performance).
I did a quick test yesterday regarding CPU temp: Playing two h.264 HD videos simultaneously and used throttlestop to monitor and TS bench to genereate 4 threads of cpu load. The max temp I saw during the test for several minutes was 80 deg C (balanced thermal profile, and throttlestop reported the CPU speed as 3.2GHz for both cores).
Regarding SATA speeds the Z2 is supplied with SATA 6GBs drives in some markets and/or as a CTO option, more information:

I like you have owned one of these since launch. I see a fair few comments about the keyboard but for me it doesn't take long for one to get used to it.With regard to fan noise i don't play games on the device so i never really hear it at all.
Trackpad could be better, but once again its not a nightmare.
The performance of the machine however is excellent. The boot time of approx 10 secs is awesome, display is excellent and its good to have network connectors on the device not just having to rely on wifi or buying a dongle (e.g. Macbook Air) to get a wired connection going.

"The AMD Radeon HD 6650M inside the dock is limited to a PCI Express 2.1 x4 link instead of x8 or x16, and the performance hit is a noticeable one"Source on this statement? It's been shown many times that graphic cards really aren't very bandwidth starved at 4x 2.0 and above. Taking a quick look at the 5870 we see the following: http://www.techpowerup.com/reviews/AMD/HD_5870_PCI...

Why do they continue to ran the SSDs in Raid 0 since you can't get TRIM?Are they just trying to suck in over paid clueless CIOs or something?

They use garbage collection instead.Not really sure what's wrong with RAID-0 if you have proper garbage collection.

According to Crystaldiskmark, the Sony Z I tested (64x2 in raid 0) showed over 850MB/sec read speeds, which clearly shows that the Z does run in 6Gbps mode (SATA-3).Sort of interesting that I email them this info and they don't even update/check.
