Frontal view, ( Acer Aspire One battery ) sun from the backThe display's vertical viewing angles are very tight with the usual 15 degrees. We can deviate horizontally to the left or right better, but only up to about 45 degrees. Beyond that, the screen clearly dims and colors fade. ( Battery Acer Aspire 4710 ) The narrow viewing angles hardly will affect the Lifebook's single user. Viewing problems first turn up when five pairs of eyes look at the screen at the same time. Ghosting can get very annoying in pictures or movies. The Lifebook NH751 proves that a better job is possible.
The 15.6 incher is equipped with an Intel Core i3-2310M (2x 2.1 GHz). The Core i3 dual core CPU isn't capable of Turbo Boost,( dell Latitude D620 Battery ) but Hyper Threading (processing on 4 threads). For more information about the processor for low-cost notebook, please see the data sheet.
The NVIDIA GeForce GT 525M ( dell vostro 1400 battery ) (1024 MB) isn't solely responsible for 3D calculations. The graphics chip, HD Graphics 3000, in the processor is enabled (GT 525M can be deactivated via Optimus). The RAM configuration is 4 GB, whereas two 2048 MB modules occupy both RAM slots.( Vostro 1310 battery ) A 5400 rpm, 320 GB HDD from Seagate (ST9320325AS) is used as the hard disk.
System information: Fujitsu Lifebook AH531
The Core i3-2310M (2x 2.1 GHz)( Sony VGP-BPS13A/S battery ) manages just as many points (2761) as the much higher clocked Arrandale generation i3-380M (2x 2.5 GHz; 2751 points) in Cinebench R10 Single 32bit. The big brother, i5-2410M (2.3 GHz, Turbo Boost) achieves a considerably faster 4510 points (64bit).
The i3-2310M achieves 7550 points in multi-threading (Cinebench R10 Multi 64bit).( VGP-BPS13A/S Battery ) So, almost as many as the currently strongest i3 processor, 380M (7811). The i5-2410M and i5-2520M achieve 9451,( Dell Laptop Battery ) respectively 10128 points via Turbo Boost 2.0. Conclusively: the 2011 Core i3, in its smallest 2.1 GHz alternative, is almost on a par with its higher clocked Arrandale predecessors. If you'd like to have high computing performance for the next few years, you should spend the 50 euros more and take the AH531 version with an i5-2410M (starts at 600 euros).

PCMark Vantage determines a score of 5320 points. ( dell Inspiron 1720 Battery ) This is on the same level as the older systems with Core i3-380M (e.g. Samsung RV511: 5432) or i3-370M (Samsung SF510). Our test system reaches 1910 points in the new PCMark 7. The dedicated graphics card ensures an advantage because another i5-2410M notebook ( Dell inspiron 1520 battery ) (Lifebook LH531; Intel HD 3000 only) tested at the same time only achieves 1855 points despite the Turbo Boost processor (PCMark Vantage: 5902).
The 320 GB HDD from the manufacturer Seagate works slowly,( Dell Inspiron 1420 battery ) as we expect from a normal rotating 5400 rpm HDD. It only reads with 57 MB/s in sequential read (HDTune). CrystalDiskMark, as the second test, records 74 MB/s (different test routine than HDTune). PCMark Vantage's HDD score shows a score of only 3339 points (sub score).
The HDD turns out to be the system's brake,( Dell Inspiron 1525 battery ) which can be seen with a look at SSD notebooks. Even if we pick out a system with a rather weak processor, such as the Samsung 900X3A (i5-2537M 1.4 GHz), 23 thousand points in the HDD sub score let PCMark Vantage's total score skyrocket to 8657 points. A direct Core i3 comparison with a SSD is difficult because such systems aren't yet available.( Sony VGP-BPS13/B battery ) An Nvidia GeForce GT 525M (1024 MB DDR3) works with Nvidia Optimus and Intel HD 3000 (in CPU) in the Lifebook AH 531. ( battery vostro 1510 ) All information about Nvidia's smallest midrange graphics card can be found in the spec sheet.
In the past, the gaming performance was slightly below that of a Radeon HD 6550 or HD 6650. ( VGP-BPS13B/B battery ) The synthetic benchmark however vary if the GT 525M or the Radeon HD 6550 compute faster. 3DMark 11 says, ( battery dell Vostro 1520 ) the HD 6550M is faster (+30%). The tessellation benchmark, Unigine Heaven, states a par (-4% for the HD 6550M). 3DMark Vantage says, the HD 6550 is a bit slower (-2%). In order to take a look at the gaming suitability, we ran three tests.
The shooter shows itself unimpressed from the "weak" i3 processor.( battery Dell inspiron 6400 ) The frame rate is 40 fps in medium settings. The GT 525M performs the same 40 fps when it's supported by a quad core i7-2630QM (Fujitsu Lifebook NH751). Gamers would have more fun with a Geforce GT 540M (devices for less than 600 euros; +14%, ~31 fps). A Radeon HD 6550M is even faster by an average of 23% in high (~33 fps).
The multi-touch screen reacts well and accurately to commands from a finger.( HP 8510w battery ) Control using a pen is not intended as with the Iconia Tab W500. The navigation around the Android 3.0 surfaces is smooth, and apps open quickly.( battery sony VGP-BPS9/B ) Using different themes for screens it is possible to organize the apps as wished. Important operating functions, such as the zooming of pictures using a double-click or by using two fingers works perfectly. The rotating of pictures in comparison doesn't work. The surface of the display has good traction properties and makes a robust impression,( Acer Aspire 4520 battery ) but is also very reflective. From time to time users should check the settings for apps that are no longer needed that may be running in the background. Should these become too many, then the reaction times become noticeably slower as a result.
