2012年12月19日Review Sony Vaio VPC-SA2Z9E/B (i7, SSD, HD 6630M) Subotebook
The SB and SA models belong to Sony’s Vaio S range. While SBs are positioned as affordable business all-rounders, the equally built SA is to cover the high priced sector. Almost 2400 euros is a lot of money for a 13 incher. But, the luxury-savvy customer is offered a lot - at least on paper. http://www.cbattery.net/lg-r405.html LG R405 Battery
Core i7 Dual Core, Radeon HD 6630M with de-activatable graphics, a 256 GB SSD in RAID0 and a matt WXGA++ screen. It is debatable if the price for this handy powerhouse is justified. However, it can’t be denied that it is a very interesting test device due to the awesome combination of highest performance and portability. Our comprehensive review will reveal all information about the luxury 13.3 incher. http://www.cbattery.net/apple-a1280.html Apple A1280 Battery

Performance
The dual Core i7-2620M (2x2.70 GHz, 32nm) has already provided power in business machines, such as HP’s EliteBook 8460p. The processor’s Turbo Boost 2.0 can clock up to 3.4 GHz (one core) and the "Dynamic Range @ Turbo Frequency Limits" can even add a bit of clock providing there is a sufficient cooling. We will devote ourselves to the themes clock rate and throttling in "Temperature". http://www.cbattery.net/dell-inspiron-1750.html Dell Inspiron 1750 battery
The dual core 2620M (TDP 35 watts) is always installed when a 45 watt 2630QM (quad core) goes beyond the cooling limits as it would be the case in 13 inch devices. It is frequently used in high performance 13 inchers, e.g. Acer’s Aspire TimelineX 3830TG-2628G12nbb or Dell’s Vostro 3350, due to the CPU’s low idle power consumption. http://www.cbattery.net/asus-x72f.html Asus X72F Battery
The Radeon HD 6630M isn’t actually designed for subnotebooks because of its strong performance (and high power consumption). Nevertheless, Sony installs it into the SA, SB and CA range. Moreover, there is adequate 8 GB of RAM and an extremely fast Samsung RAID0 SSD that bids a memory capacity of 256 GB. Again, the S range typical Speed Mode switch that disables the HD 6630M is present. http://www.cbattery.net/asus-a42-m70.html Asus A42-M70
The i7-2620 scores 9452 points in Cinebench R10 Multi. That is a bit more than an i5-2540M with 9154 points (also 4 threads). Its quad core brother, 2720QM (8 threads), manages 14273 points (+35%) in test notebooks. We see: The processing speed’s difference compared with a Core i5 is low.
Is the slim and light 13.3 incher’s cooling efficient enough to keep the CPU performance upright during consistent load? We look at the i7-2620 in various other devices. Almost all 2620M candidates reach about 9450 points (+/- 150) in Cinebench R10 Multi. Only the Apple Macbook Pro 13 inch 2011-02 MC724LL/A fails this rate due to throttling. http://www.cbattery.net/dell-xps-15.html DELL XPS 15 battery
Four of eight laptops achieved 3.1 points in the Cinebench R11.5 CPU 64 bit test. The Vaio SA2 test device doesn’t belong to them because it is on the same level as the Vostro 3350 and XMG A501 with 3.0, respectively 2.9 points (-3%). Again, it is only the aforementioned MacBook that merely reaches 2.6 points due to throttling (-16%). Short: The i7-2620M calculates on the expected level in pure CPU performance. The cooling seems sufficient for normal load scenarios. http://www.cbattery.net/acer-aspire-8920g-series.html Acer Aspire 8920G battery
What does the processing performance look like together with CPU, graphics, RAM and SSD? PCMark Vantage and PCMark 7 provide the information. The total results of 10833, respectively 3448 points are very high, but not as good as expected in the case of Vantage. The considerably less expensive consumer, XMG A501 (Crucial Real SSD C300) achieves 10833 PCMark Vantage points with the same CPU (PCM7 score not available). http://www.cbattery.net/toshiba-satellite-l500-series.html Toshiba Satellite L500 battery
PCMark 7 (3448 points) really likes the Samsung SSD disk because only gaming laptops and workstations equipped with a 2630QM or 2920XM (+SSD) can reach higher scores. The Alienware M18x (4579), the Fujitsu Celsius H710 WXP11DE (3695) and the XMG P501 PRO (4208) would be mentioned here. Normal 2620M laptops without SSD are located as low as 2000 points (Vostro 3350).
The named behemoths also have better graphic cards, and thus their advantage should actually be greater. Therefore, it seems remarkable that a small 13.3 incher can close in on the machines of the gaming and workstation sector with the mere support of an SSD. http://www.cbattery.net/hp-pavilion-dv8000.html HP Pavilion dv8000 battery
The reason for this high score in application performance is the Samsung SSD’s fast accesses. They drive the PCMark Vantage’s HDD score up to 15599 points (Vaio Z13 with quad SSD: 13055). The speedy accesses let the music, productivity and communication score skyrocket. The productivity score is 13282 points (Vaio Z13: 9818). High performance laptops with a rotating hard disk (7200 rpm) achieve 6200 at best (e.g. HP Elitebook 8540w). http://www.cbattery.net/hp-pavilion-dm1.html HP Pavilion dm1 battery
The synthetic DirectX 11 benchmarks, such as Unigine Heaven 2.1 (11 fps), confirm that the AMD Radeon HD 6630M’s performance is close to that of an old HD 5650 or a GT 525M (12 fps). The currently popular GT 540M (13 fps) in consumer laptops also seems to be a tiny bit faster. http://www.cbattery.net/dell-xps-m1530.html Dell XPS M1530 battery
3DMark11 (P 1023) runs a bit slower with a GT 540M (P ~950 points above all test devices). The Dell Vostro 3550, with the same CPU/GPU configuration as our Vaio, achieves 990 points and is thus almost equal. To achieve more points, an HD 6770M (~1500) or a GT 555M (~1300) would be due. However, such GPUs are only built into 15 and 17 inchers. http://www.cbattery.net/hp-593554-001.html HP 593554-001
The classic 3DMark 2006 (1280x1024) finishes on the Radeon midrange category with 7057 points, which is slightly below a GT 540M (~8000 @XMG A501 with 2620M). A GT 525M (7400) together with a strong CPU achieves about the same score. For example in Dell’s XPS 15z (2620M). http://www.cbattery.net/acer--as10d75.html Acer AS10D75
Gaming Performance
The AMD Radeon HD 6630M (1024 MB) is a DirectX 11 GPU and the successor card of the 2010 HD 5650. It clocks with 485/800 MHz (core/memory) in the test device and corresponds to the manufacturer’s specifications. The GPU could present games, such as Dirt 3, Call of Duty: Black Ops, Mafia 2 or Battlefield, in high details smoothly in the previous test devices (Vostro 3450/3550, ThinkPad Edge E420s). High details are 1366x768 pixels in our case. http://www.cbattery.net/hp-g61.html HP G61 battery
Battlefield: Bad Company 2
The shooter can be played on 1366x768 pixels and on high detail levels on the Vaio. However, 32 fps don’t leave any room to switch to the native WXGA++ resolution. The GT 540M is 5% faster in this game, but a GT 525M (-6%) is surpassed. Only 28 fps were achieved in the Vostro 3550 with the same CPU but older driver. http://www.cbattery.net/lenovo-l08n6y02.html Lenovo L08N6Y02 battery
System Noise
The Vaio SA2 delivers a mixed show in regard to noise. The Vaio is always audible in idle (Stamina mode) and the fan is never off. However, the user has to get very close to the 13 incher in order to hear this quiet whirr of 30 dB (A). Occasional load while surfing on the Web or other simple tasks lets the level increase gently to 32 dB (A). http://www.cbattery.net/hp-pavilion-dm4.html HP Pavilion dm4 battery
A downright pussyfooter in idle - perfect, or? But that doesn’t stay that way for long. The 13.3 incher mutates to a noisy companion when the processor and/or Radeon graphics (Speed mode) are put under load. The clear noise reaches a level of 41 dB (A) quite fast (3DMark Vantage, Cinebench R11.5). We measure 47.8 dB (A) in the stress test (CPU&GPU). At least the fan rotates constantly and hardly ever changes its speed. http://www.cbattery.net/sony-vgp-bps13a_q.html Sony VGP-BPS13A/Q
Temperature
Since the fan also rotates constantly in Stamina mode (HD 3000 enabled) during idle, waste heat isn’t accumulated. Consequently, the figures stay in the blue, low range. The selective temperatures rise quickly during maximum stress over several hours. We measure 48 degrees Celsius in the vent’s vicinity. However, this is only a selective rate. The average is 37 degrees Celsius. The fact that the wrist-rest doesn’t heat up beyond 33 degrees is pleasing. http://www.cbattery.net/acer-aspire-5740g.html Acer Aspire 5740G battery
Battery Life
There is a wide margin of 50 watts between idle and high load (CPU/GPU). The Sandy Bridge Core i7 and the HD 6630, as the biggest power consumers, can restrain their power requirement very adaptively depending on the load. This proves that Turbo Boost works. The idle power consumption is between 9 watts (Stamina mode, Intel HD, minimum brightness) and 21 watts (Speed mode, HD 6630M, maximum brightness). http://www.cbattery.net/samsung-aa-pb4nc6b.html Samsung AA-PB4NC6B
3DMark 2006 consumes 49 watts. It’s even 60 watts in the stress test. We see the very moderate CPU throttling confirmed here because the power consumption remained constant during the stress test (4x 2.4 GHz @multi CPU stress). Thus, performance fans don’t have to fear that they will "lose" a lot of power. The compact 90 watt power adapter (286 grams) is very well designed for the maximum power consumption. http://www.cbattery.net/dell-xps-m1710.html Dell XPS M1710 battery
Verdict
The last time we had so much computing power in a light 13 incher was with the 13.1 inch lightweight, Vaio VPC-Z13Z9E, whose successor (VPC-Z21M9E) is currently being launched onto the market. The fast Core i7 2620M (2x2.7 GHz), together with the RAID0 SSD with fast read and write speeds, ensures gigantic scores in system performance. Loading and installing programs within fractions of a second. The boot process takes 10 seconds. http://www.cbattery.net/hp-511872-001.html HP 511872-001 battery
Gamers and multimedia designers will take delight on the AMD Radeon HD 6630M. The dedicated GPU doesn’t impair mobility thanks to switching to the Stamina mode (hardware switch). The runtimes of 3:30 to 4:50 hours (without battery slice) aren’t awesome but acceptable for the powerhouse. http://www.cbattery.net/acer-as10d5e.html Acer AS10D5E
The workmanship and the plain looks will appeal to demanding office users. Unlike our first Vaio SB1 test device, the case’s stiffness is very good. The lid is kept firmly in place and has an unyielding surface. In line with the still low weight (1652 grams) and the slim design, the user will be able to successfully make a smart appearance in public. http://www.cbattery.net/hp-compaq-business-notebook-6720s.html HP COMPAQ 6720s battery
But it’s not just showing off with pretentious hardware that the Vaio VPC-SA2Z9E/B is good at. Touchpad and keys have a big, work suitable layout. The typing feel convinces with a clear pressure point and firm stroke. Professionals and business users will like the battery slice option, the built-in 3G modem and the docking port. A desktop replacement is created with these supplies, which can be very strong on the one side and can last long on the other. http://www.cbattery.net/lenovo-ideapad-s10-2-2957.html Lenovo IdeaPad S10-2 2957 battery
The anti-glare and bright WXGA++ screen prevents a "Very Good" in the rating because of weak colors (no sRGB color spectrum, low contrast) and the narrow viewing angles. The screen is suitable for the subnotebook’s mobile purpose. But we would have hoped for a premium display, as was the case in the Vaio VPC-Z13Z9E (sRGB), in the premium price range of almost 2400 euros. http://www.cbattery.net/lenovo-g570.html LENOVO G570 Battery
A very high noise and high temperatures during extreme load are additional drawbacks. However, these drawbacks are irrelevant during normal use because waste heat and noise are far less striking here. http://www.cbattery.net/asus-x72jr.html Asus X72JR Battery
The Vaio VPC-SA2Z9E/B will certainly not be for everyone due to the high price of almost 2400 euros. On the other hand, there aren’t any alternatives should 3D performance, a low weight, business suitability (matt, input devices, docking port) and awesome application performance in 13.3 inches be desired. There are a few light 13.3 inch laptops with a similar processor and partly even with SSD. However, the combination with de-activatable 3D performance is still something rare. http://www.cbattery.net/toshiba-pa3757u-1brs.html Toshiba PA3757U-1BRS
One alternative at a similar price is the Sony VAIO Z21Q9E/B with an external AMD Radeon HD 6650M (connected via LightPeak cable), which will be launched onto the German market in the next days. Consumers will take a look at the Acer Aspire TimelineX 3830TG-2628G12nbb (starts at 1200 euros), a 13.3 incher with Core i7-2620M, 120 GB SSD and NVIDIA GeForce GT540M. http://www.cbattery.net/fujitsu-fmv-a8270.html Fujitsu FMV-A8270 battery

The anti-glare and bright WXGA++ screen prevents a "Very Good" in the rating because of weak colors (no sRGB color spectrum, low contrast) and the narrow viewing angles. The screen is suitable for the subnotebook’s mobile purpose. But we would have hoped for a premium display, as was the case in the Vaio VPC-Z13Z9E (sRGB), in the premium price range of almost 2400 euros. http://www.cbattery.net/lenovo-g570.html LENOVO G570 Battery
A very high noise and high temperatures during extreme load are additional drawbacks. However, these drawbacks are irrelevant during normal use because waste heat and noise are far less striking here. http://www.cbattery.net/asus-x72jr.html Asus X72JR Battery
The Vaio VPC-SA2Z9E/B will certainly not be for everyone due to the high price of almost 2400 euros. On the other hand, there aren’t any alternatives should 3D performance, a low weight, business suitability (matt, input devices, docking port) and awesome application performance in 13.3 inches be desired. There are a few light 13.3 inch laptops with a similar processor and partly even with SSD. However, the combination with de-activatable 3D performance is still something rare. http://www.cbattery.net/toshiba-pa3757u-1brs.html Toshiba PA3757U-1BRS
One alternative at a similar price is the Sony VAIO Z21Q9E/B with an external AMD Radeon HD 6650M (connected via LightPeak cable), which will be launched onto the German market in the next days. Consumers will take a look at the Acer Aspire TimelineX 3830TG-2628G12nbb (starts at 1200 euros), a 13.3 incher with Core i7-2620M, 120 GB SSD and NVIDIA GeForce GT540M. http://www.cbattery.net/fujitsu-fmv-a8270.html Fujitsu FMV-A8270 battery
