The keys have a distinct stroke, clear pressure point and firm stop. The keyboard's entire surface is sufficiently fitted for normal typing. A harder stroke can cause it to yield slightly. The keys have a large distance to each other and the arrow keys are separated from the others. HP 441131-001 Marks for touch-typists on the F and J keys are difficult to feel. In short: The keyboard is good and particularly the feedback while typing is very pleasant due to the clear key drop. If the keys had a conical inward curve, a "Very Good" would have been due.

The Elan Smart-Pad offers many settings for customization, as usual. For example, users who prefer using a one-finger scroll bar at the edge can simply enable it. Users who can't get enough of multi-finger gestures can also enable three-finger swiping. Thus, the user can quickly go back to the desktop from any Windows application or switch among Windows.HP HSTNN-OB37

The Elan pad's surface is sensitive up to the edges and pleasantly matt, but not smooth. The pad keys work almost noiselessly, but have a too short key drop. The latter lessens the operating feedback in contrast to the clear key drop of the keyboard.HP HSTNN-OB38

The 11.6 inch screen from Samsung (model LTN116AT01) has a resolution of 1366x768 pixels. This high resolution has become standard in 11.6 inch devices - much to the user's delight. In opposition to the obsolete 10 inch netbook resolution of 1024x600 pixels, it improves the desktop's manageability. HP HSTNN-UB37

The TN screen's contrast of 143:1 is very low but not surprising in this low-priced device category. However, the really important criterion for the Samsung 305U1A's mobile use is its brightness – which is impressive. The matt screen has an average brightness of 241 cd/m2, which is even brighter than the majority of office laptops. Important for outdoor use: The brightness isn't reduced on Charger power.HP HSTNN-XB37

The color spectrum, which we compare with AdobeRGB, sRGB and the screen in the Latitude E6520 FHD as well as the Vaio Z13 (each transparent), is very narrow. Small-sized professional screens are very scarce. Examples would be the (expensive) Vaios of the Z series (FHD & WXGA++, matt). These usually cover at least sRGB (grid in center ICC picture). However, this quality is only important for professional image editors.HP RQ203AA

ICC Samsung 305U1A vs Vaio Z13B7E HD+(t)Samsung makes the right decision and installs a matt TFT. It allows use in daylight and in the sun. The 11.6 inch screen didn't have any problems with legibility in overcast conditions, in which we took our pictures.HP F2024

Frontal view, cloudyThe Samsung 305U1A's viewing angles are viable horizontally, but very poor vertically. The colors remain true up to about 45 degrees. The viewer's eyes may only deviate 15 degrees from above or below before the picture fades vertically. We experience extremely inverted colors at a vertical deviation of 25 degrees. The viewing angle behavior described here is common for about 80% of our test devices (low and medium price range).HP F2024-80001

AMD E-450 APU with Radeon HD 6320 (IGP)Samsung equips the 11.6 inch laptop with the Bobcat APU, AMD E-450 (2x 1.65 GHz). The so-called Accelerated Processing Unit with a TDP of 18 watts has an integrated graphics unit with DirectX 11 functions and a UVD3 video decoder for HD videos (MPEG-2, H.264, VC-1). The Radeon HD 6320 beats the latest Intel HD 3000 (notebooks) with 80 shaders and a UVD3 processor. We won't even mention the GMA 3150 (Atom netbooks).HP F2024-80001A

The APU only has an L2 cache of 1024 KB. The core sits on the AMD A50M chipset and is accompanied by 4096 MB of DDR2 RAM. Samsung installs the 64 bit Windows 7 Home Premium and the 64 bit APU is exploited perfectly.HP F2024A

Cinebench R11.5: CPU @1.65 GHzWe compare the AMD E-450 (2x 1.65 GHz) with the previous E-350 (2x 1.60 GHz) and with the Intel Atom dual core N550, still on the market. The Atom dual core has the Hyper Threading advantage of four computing cores. The difference to the E-350 should be low, if at all visible, in the CPU performance. Level 1 and 2 caches are identical (128, respectively 1024 KB).HP Mini 5103 Charger

The multi core benchmark, Cinebench R11.5 64bit is to show us if the lack of Hyper Threading is a disadvantage for multitasking operations. The test system achieves 0.64 points. That is equal to all previous E-350 devices: 0.6 points. We don't have a 64 bit score for the N550, so we use Cinebench R10 Multi 32bit: 2027 points for the E-450 and 1400 points for the Atom N550 (average). The E-350 again has an identical score of ~2000 points. The N550 is slower by 30% according to that.HP ProBook 4405 Charger

The processor can reduce its clock to 800 MHz in idle. The Bobcat cores don't have Turbo (only in Llano APUs), and thus 1.65 GHz is always run in medium and high load. The user can intervene by limiting the clock in the Vision Control Center.HP ProBook 4405s Charger

The synthetic computing examples don't let the AMD E-450 look better than its predecessor, E-350. But what about the combined application performance of this specific test device? The CPU weak Samsung might also convince with a fast hard disk, respectively SSD, RAM and graphics card (HD 6320). HP ProBook 4406 Charger

We use PCMark Vantage and PCMark 7, which check all the components as a whole. 2640 points, respectively 1005 points are the tight results. At least the Samsung 305U1A can stand out from the E-350 test range that only achieves 85% of the performance (2250 points). Since the MSI Wind U270 with an E-450 also only manages 2268 points, we ascribe the increased performance to the fast hard disk. The PCMark Vantage gaming score of 2202 points is only marginally higher than with an E-350 (~2000 points).HP ProBook 4406s Charger

Outside the netbook or Fusion comparisons, it remains to be said that our Samsung 305U1A is significantly weaker than, for example, a simple office device with a Core i3 2330M and integrated Intel graphics. The Asus Pro P53E manages 4810 points, respectively 1768 points (PCM Vantage, PCM 7). However, there is a contrasting picture in 3D performance; see gaming performance.HP ProBook 4410s Charger

Everyone is talking about hardware support via the graphics, which unloads the processor in general calculations via OpenCL, OpenGL or CUDA (Nvidia). The HD 6320 supports OpenCL - can we exploit this? We let our Samsung 305U1A render a video (H.264 FHD 50i) with CyberLink's Power Director 10, which takes 15:40 minutes. GPU support unfortunately isn't achieved even after installing the AMD Media Codec Pack in the latest Catalyst driver. HP ProBook 4411 Charger

It's also frustrating here that the Asus Pro P53E with an Intel HD and Core i3 standing beside it, renders the same clip in 3:27 minutes, including Intel's QuickSync Video hardware support. Apart from the poor rendering performance, working with Power Director 10 on the Fusion system is amazingly smooth.HP ProBook 4411s Charger

HDTune reads on average with 72 MB/s. Although this isn't an unusually high rate, it is in the midfield of simple 5400 rpm hard disks. CrystalDiskMark achieves 90 MB/s. This throughput is at the upper end of 5400 rpm HDDs and in the midfield of 7200 HDDs. Samsung could have used a 7200 rpm HDD, but the noise would likely have been overpoweringly loud under certain circumstances. HP ProBook 4412s Charger

The HDD scores in PCMark Vantage and PCMark 7 add a few points to the high throughputs. 3010 points (PCMV) are however still remote from the 4500 point that a speedy single 5400 rpm HDD could manage. The PCMark 7 Storage score finishes with 1456 points. This can also be seen as midfield; 7200 rpm HDDs are only 10 to 20% faster (e. g. Dell XPS 15z +15 %).HP ProBook 4413 Charger

The AMD Radeon HD 6320 (IGP) is practically the performance behemoth among the integrated graphics units of the AMD C and E series. In comparison to the HD 6310 of the E-350, the clock can now increase from formerly 500 to now 600 MHz via Turbo Core. Since the 80 shaders and the 40 nm manufacturing process hasn't changed, the measurable advantages stay within narrow limits.HP ProBook 4413s Charger

The old 3DMark 06 gathers 2411 points, which is still 15% more than the E-350 range, e. g. the ThinkPad Edge E325 (2048). However, that can't hold a candle to a HD Graphics 3000. These devices range between 2500 and 4600 points (105 to 190%). 3DMark Vantage finishes with 951 points. The E-350 devices are 15% below that in the best case. The Intel HD is again 119 to 217% faster. 3DMark 11 is newer and finishes with 338 points. The E-350 devices are only slightly below that with 82% of the score. There are no rates available for the Intel HD.HP ProBook 4415 Charger

The frequently mentioned advantage of an AMD Fusion APU is the high GPU computing performance compared to Intel's processor graphics. The comparison however only works when netbooks equipped with the Intel Atom N550/N450, available on the market, are compared. This is synonymous with the gaming performance: Our test device can at most beat these weak systems. The 3D performance is extremely low compared to "normal" notebooks - even ones with an Intel processor graphics or low voltage processor. HP ProBook 4415s Charger

We tried a range of current games and only the oldest one from 2008 (Left 4 Dead) could be played fairly smoothly (low details). A HD 3000 system, such as the Acer Aspire 3830TG-6431 (2410M) doesn't manage much more either in Civilization 5. The car racing game, F1, manages 30 fps with the Intel graphics (ultra low,HP ProBook 4416s Charger Toshiba Portégé Z830-10N, 2367M) and not only 16 fps like our test device. The same is evident in The Elder Scrolls V: Skyrim, which achieves 17 fps on the Toshiba Ultrabook. A 2410M processor graphics is required for 18 fps (Aspire 3830TG-6431). We notice the lowest difference in Anno 2070 in low details: 28 fps versus 30 with an Intel HD 3000 (@ Lenovo IdeaPad U300s, Toshiba Portégé Z830-10N). An overview of the Radeon HD 6320's (IGP) gaming performance can be found on the GPU's data sheet.HP ProBook 4418 Charger

The cooling system does credit to Samsung's name. It is usually silent and isn't disturbing during load. Silent Mode (FN key) that limits the processor clock to 800 MHz is available. Of course, this reduces the performance. However, this mode is not actually necessary, since the fan is always switched off in idle during normal mode. Only the HDD's noise (barely audible, 30.6 dB (A)) or its clicking (32.6 dB (A)) is measurable here.HP ProBook 4418s Charger
