The Sandy Bridge CPU Core i5-2520M ( 2x2.5 GHz ) Sony VGP-BPS2A Akku was part of our pre-production unit Vaio SB. In trade, the Vaio SB but only with the lower clocked i5-2410M (2x2.3 GHz ) or higher i7-2620m (2x 2.70GHz) CPU to find. The turbo -clock is at 3.2 GHz and can go under the 2.0 turbo concept depends on the temperature and beyond. Dell Inspiron 1545 Akku The 2011 cores Intel can use the " Dynamic Range Increase @ Turbo Frequency Limits "the turbo mode, if the permitting cooling (temperature exceeded a certain limit).

 

The graphics chip HD 3000 Graphics in theSony VGP-BPS2B Akku processor (650-1300MHz) with a AMD Radeon HD 6470M combined (512). Because after all Radeon does not work with Nvidia Optimus, there's a stamina / speed switch that lets you choose the graphics card manually. Technically, the manual transmission with interruption of several seconds and flickering image on the level of 2009.The RAM -equipped in the Dell Inspiron 1750 Akku standard is 4 GB , our pre-test sample was with 6 GB equipped. Four gigabytes are soldered to two gigabytes on the single RAM slot plugged. The premium unit SB1A9E / B is equipped with 8 GB equipped.

Single-core calculations are rare in the daily work in the weight. Anyone with CyberLink's Power Director video encoded, the benefits of multi-threaded with high speed. The i5-2520M (4 threads) takes 10 128 points out Dell Inspiron 1440 Akku ( 64bit Cinebench R10 multi ). The smaller 2410M is still at 9451 points. The 2010s i5-460M (4 threads) loses much: 8060-8342 points (eg, Acer Aspire 5820TG ).

The PCMark Vantage ends at 7357 points . Dell XPS M1330 AkkuThat is remarkable, previously managed the most i5-460M- systems up to 6,000 points ( Acer Aspire 3820TG-5464G75nks ), if also with a rotating HDD were fitted. The standard unit VPC-SB1S1E / W comes with its i5-2410M only 6187 points . The Communications Sub-score shows a significant difference (9299 vs. 5990 points). The reason: The i5-2520M our pre-production unit has the business functions of Intel VT-d, Trusted Execution Sony VGP-BPS2C/S Akku Technology and AES New Instructions.

The HDD sub-score of PCMark Vantage is at 3380 points , Sony VGP-BPS8A Akku what a slightly above-average min value for a 5200 U / HDD is. Only fast 7,200 rpm / min for the internal memory can topped 3,500 points. SSDs playing in a different league (20 to 25 thousand points). The hard drive ( 500 GB ) from Western Digital reading with 64 MByte / s in sequential read . The values ​​of the series device are identical (same HDD model).

Even the nomenclature of the AMD Dell Inspiron 1318 AkkuRadeon HD 6470M (512MB) makes it clear that it is the DirectX 11 GPU for a beginner is card. The GPU is clocked at 800/900 MHz (core / memory) about the AMD specification. Some application programs using the 160 stream processors, DirectX 11, OpenGL 4.1, DirectCompute OpenCL 11 or use them for calculations. In terms of film provides UVD3 Video Decoder for hardwareDell XPS M1530 Akku support (MVC, DivX, xVid, MPEG-4 AVC/H.264, VC-1, MPEG-2, Adobe Flash video.

The gaming performance is not the first evaluation, Dell Inspiron 1420 Akku4615 3DMarks06 but are an indication of Entry passable gaming. We have a game with an older sample (Left4Dead) and an actual game made ​​(Mafia2).For a round of Mafia 2 or StarCraft 2 is the Radeon HD 6470M have to, but only in a coarse resolution and significantly trimmed details . Who is on older or less demanding games crashes, for example, is served with Anno 1404, Dell Vostro 1400 Akku Fifa 11 Left4Dead or liquid. Who wants to find out exactly who should be the Raden HD 5470 view. The 6470M is expected to slightly due to the higher number of shaders and faster through the Sandy Bridge processor are above their capacity.

When volume makes a passable but not SB Vaio very good figure. Dell Inspiron 6400 Akku The fears of some readers, the worst of the partially covered outlet expected, but we are not justified. We have the BIOS update run R1030H4 ( BIOS update Vaio VGN-SB1 ). Pre-series and serial device behave identically. In the idle (Stamina mode) remains the Vaio SB always audible , HP Pavilion dv2000 Akku even if temporarily turns off the fan. Now is the rotating disk the purring basic level of 31.5 dB (A) . If the fan anfährt or changes its number of revolutions, so that he makes a slow , constant acceleration . The pattern of slow growth and mild decay has us pretty much.

This is deceptive, however, do not get over one thing: Dell Inspiron 1501 AkkuWhere are the processor and / or Radeon graphics (speed mode) loaded, the 13.3-incher makes a mighty noise. The Bright noise reached fairly quickly (3DMark Vantage, Cinebench 11.5), the 40 dB (A) level mark. In the stress test ( CPU & GPU ), we measured 47.7 dB (A) . After all, the fan rotates evenly and rarely changes the speed. At the end of the last stage, we hearHP Pavilion dv6000 Akkua gentle but very fast decay (20 seconds).

Since the fan is also in the mode StaminaHP Pavilion dv6700 Akku (HD 3000 active) never shuts off constant, no waste accumulates in the chassis and everything stays in the blue region. Under extreme stress for several hours, the occasional temperatures rise significantly. Near the exhaust vent, we measured 47 degrees Celsius. This is only a selective value, the average is just 31.5 dB (A) .

The temperature sensors on the processor during the HP Pavilion dv9000 Akku stress test report up to 96 degrees . The GPU is only heated to 85 degrees. The system remained stable during the several hours of tests, but gave us a reason to look again carefully. While the GPU in any scenario, its 800/900 MHz clock limits, set at the CPU throttling (see screen shots). A CPU benchmark as wPrime or Prime95 makes for easy lowering the clock speed to about 100 MHz. Hwinfo marks the second core with a red "throttling". This is also the core that reached HP HSTNN-OB42 Akku 96 degrees with the highest temperature. In stamina mode occurs in wPrime no more throttling.

The mini-stereo speakers deliver the keys of an extremely height-heavy sound . HP COMPAQ 8510p Akku The volume is relatively high, but nobody will stop the rattling sound in the ears voluntarily louder than 50%. The Dolby sound enhancements (Surround Audio Enhancer) are effective only for external speakers.The 13.3-incher with its 50-watt-hour lithium-polymer battery ( 4540 mAh ) provides strong terms. While surfing the Web (via wireless ) is good enough for five hours . The run time was in Stamina mode (Intel GMA 3000) at about 100 cd / m² brightness measured. HP COMPAQ 8510w Akku Our production model VPC-SB1S1E / W with i5-2410M held in the WLAN test by the same time: 5:13 hours .

With down-regulated brightness, and idle, the Vaio SB hold much longer. HP COMPAQ 8710p Akku The reader-test does not end until after 8:40 hours (see text at min. brightness). For a Blu-ray decode, the hardware more than a DVD, hence the term reduced to three : 57 hours (-21 minutes as opposed to DVD). Can be started until the next film session pass, Acer UM08A51 Akku only 2:47 hours ( charging time ).

The energy consumption shows something that is very typical for HP COMPAQ 6720t Akku Sandy Bridge Systems: Between idle and high load ( CPU / GPU ) is a very large wingspan . This is positive because it shows that the adaptive energy intake (turbo boost) functions. The idle power consumption is between 10 watts (Stamina mode, Intel HD, lowest brightness), HP COMPAQ 7400 Series Akku 19 watts (speed mode, HD 6470, the highest brightness). The load operation (speed mode) suggests the opposite scenario. 3DMark2006 fails with a 55 watt impact. In the stress test then it is even 66 watts. The compact 90 watt power supply (309 grams) it is well designed and can charge the battery even more. This type of power supply also powers the docking station.

With a healthy mix of business features, good workmanship and all-round Samsung R65 Akku performance earned the Vaio VGN-SB1Z9EB a solid GOOD in the overall standings. The best scores, it reaps at the very processor-driven application performance and low weight one. The i5-2520M (2.5-3.2GHz), our test unit is (currently) not found in the trade. Instead, when the self-service models to 1,300 € a Core i5-2410M (2.3-2.9GHz) on board. The power difference is less than 10% (Cinebench 11.5, Multi), so the performance evaluation Samsung R70 Akku of this test can also apply a flat rate for production vehicles.

The Spartan look is pleasing to the office user. Together with the low weightSamsung R710 Akku and slim design the 13-incher makes a smart impression in public. Prior to the Apple community for bragging but runs into space, to flexibly are areas of the base plate, the key area and the display hinge. Touch pad and buttons have a large, labor-compatible layout . It offers a successful writing Samsung R718 Akku experience feedback, the mouse buttons, however suffer from a weak key stroke .

Mobility on the part of the coming summer is five hours duration and bright , Samsung R720 Akku non-reflective semi-Displa y as saved. However, this is not a high-quality, color fidelity TFT , as we were able to experience it the Vaio Z13. The extremely low contrast and pale colors bring forth any pro-worker screen behind the stove.

A new feature is the dock - and the battery Acer Aspire One D150 Akku slice option in the price range ( from 999 € ). The switchable graphics inherits the SB series of quasi-Z13 (no 3-way switch for more). At the convenience of an automatic changeover Nvidia Optimus, which offers the same energy saving effect, the manual comes AMD Radeon shutdown not approach.
