HP 635 LH416EA Notebook Review

With the series 635, HP laptops offer bargain for beginners. With prices in the area of ​​the netbooks that offer 15.6-inch screen and optical drives for a much stronger material.

The books 635-series is based on AMD's Fusion platform (chipset A50M) with an AMD CPU-240-E and the AMD HD 6310 integrated GPU. Depending on the model, the processor is either a 1.5 GHz single-heart-(E-240) or a 1.6 GHz dual-core CPU (E-350). Other differences may exist in the RAM, hard drive size and type of operating system.

Our test sample, the LH416EA # ABD HP 635 is based on a E-240 CPU with 1.5 GHz speed, 320 GB hard drive, 2048 MB DDR-3 and 64-bit Windows 7 Home Premium.

The casings of the HP 635-are fairly standard for laptops with 15.6 inch screen, measures 247 x 376 x 32 mm (9.7 "x 14.8" x 1.26 "). The total weight of the laptop is 2500 grams (5.5 pounds), with the addition of a charger 240 grams (0.53 pounds). For colors, HP has opted for the black and copper, which gives the laptop a professional appearance.

These notebooks are made entirely of plastic. Their surfaces are deflected under the pressure quickly, and can be hidden in a deep almost everywhere. This can be seen with the lid, you can almost run through it, until something to block the transport.

The keyboard and palm rest area is much more robust, which is good, because they are more exposed to stress in daily use. The display frame is in the hands of two hinges with a tight grip. To open this screen, you must use both hands, otherwise the base will tilt the screen up.

The finish is surprisingly good at this price. Sometimes, the rustle of plastic, but can not find anything that could seriously diminish the value of the laptop. Parts of the walls still show a strong production of HP and placed where they belong. As a duck (Citroen 2 CV), an old French car in which everything fits, but audible chirps evoke shivering.

A question immediately comes to mind: If you have to accept disadvantages in relation to the connection on a laptop cheap 350 euros? Here LH416EA # ABD HP 635 responds with a clear no. All the connections you need for your daily work are provided.

Three USB-2.0-plug can be found on both sides, one on the left side and two on the back right side, then USB cables are not in the way of the mouse. For connection to external monitors, the HP 635 is both a HDMI and a VGA connector. A DVD burner is on the right side.

To the left is to plug a headset (one audio / mic, 1 audio output / headphone), an RJ45 network connector and a card reader for SD and MMC memory cards. Neither the front or the back of the HP 635 LH416EA # ABD has no outlet.

The HP 635-series entry-level use 15.6-inch laptop with a diagonal of 39.6 cm. They are LED backlit and have a matte surface that creates almost no reflection.

The LCD can display a resolution of 1366 x 768 pixels with the usual 16:09. With VGA and HDMI interface, additional monitors can be connected. Through HDMI, a maximum resolution of 2560 x 1600 pixels possible. Through the VGA port, the maximum is "only" 2048 x 1536 pixels.

The combined operation with internal and external display is possible, you can clone the contents of the internal display screen connected, or stretch the desktop across two screens.

We measured a value of 1.33 cd/m2 black for the screen, resulting in a contrast of 149:1. The colors on the HD screen displays rich and look good. For a professional, however, the color space insufficient. As the images resulting from the ICC, the color space display does not even begin to match the reference area of ​​different colors (Apple / Adobe / sRGB). It works well, because no one would expect to see professional graphics work on this laptop.

A gloomy picture, however, revealed a "bad-smiley-effect" (the first two corners and the entire lower area of ​​the screen is not only light, but in reality, a strong work in grayscale. Office, which mostly use a light background, this effect is truly remarkable. Dark Pictures or video material, this can be a bit 'annoying though.

Outside, scores and matte screen is readable in direct sunlight. We took pictures with the sun high in the zenith, but our test video was easy to discern on the screen.

Seen from the front of direct sunlight, the colors and contrasts are easy to see. By moving the side view of the decline of these outdoor areas fast enough.

Viewing angles of 15.6-inch screen is surprisingly large, with 635 # ABD HP LH416EA for a laptop that costs only 350 euros. Display the test image on this panel could be the front and sides without any major loss. Only when the screen is tilted back or forward, the loss of contrast and color intensity. The visible image is reversed, say the fires quickly.

Although 635 LH416EA # ABD HP essentially made a good impression on the spot here, we could only shake our heads over the choice of CPU. AMD 1.5 GHz E-240 single-core processor does not support Hyper Threading, so there is not even a second virtual core to help the inner core with its handling chores. Consequently, the multitasking depends only on time slots. In addition, AMD also E-240 waives any turbo mode.

Radeon HD 6310 GPU and memory bus controller is integrated into the CPU. Processing power is approximately the same level as the Intel Atom N280 and Atom N450. The CPU core has access to 512 Kbytes L2 cache, an L3 cache is not present. The E-240 is manufactured using AMD's 40nm process and has a circulation of maximum power of 18 watts.

More information about AMD processors and comparative data with other single, double and quad-core can also look at large-scale databases.

Synchronization errors in the interfaces was not detected by our software DPC Latency Checker. As the display produced without measuring a red bar, so that no restrictions should be feared in the work audio / video.

We tested the performance of Maxon Cinebench CPU render, the R10 version (32/64 bit) and R11.5 (64-bit). Since the E-240 is a single-core processor, multi-core test was omitted. The CPU has reached 891 points Cinebench R10 (32 bit) and 988 points (64 bits). For Cinebench 11.5, we have found points to 0.26.

Thus, the E-240 accuracy outperforms Intel Atom N450/N470 and clean AMD C-50 APU. Even low-cost, entry-level line CPU Intel Celeron is much better than here.

PC Mark Vantage, HP 635 LH416EA # ABD place in the 1407 points, namely the level of performance the netbook Samsung NC210-A01DE NB550D or Toshiba. Running PC Mark 7 HP has brought 635 to 707 score points.

We currently have no value compared to other notbook using E-240 processor available. They recorded scores of reference are on average 15 percent less than the value of the E-350 1.6 GHz dual core processor used in Lenovo G575. Comparison of results PC Mark Vantage, 635 HP LH416EA # ABD Lenovo even further behind at -35.8%.

HP 635 uses HD 6310 GPU built into the CPU for graphics processing. For its lack of dedicated memory and performance that qualifies as an entry-level GPU. With RAM share the CPU with the GPU, only 1.6GByte 2 GB of RAM installed for use by the CPU. HD 6310 GPU is comparable to a GeForce 9400M or integrated Intel GMA HD older.

This is reflected in the benchmark video, where E-240 HD 6310 integrated CPU reaches 7380 points in 3D Mark 2001SE and 5339 points in 3D Mark 03 3D Mark 05 scores came in with 3299 points and 1971 points in 3DMark 06 has been shaken the last point reference in 3D Mark 11, 635 HP received 252 points, and the Radeon HD 6310.

To see how good or bad, these values ​​are, we compared them with Lenovo G575-4383: The benchmark results. This 15.6-inch 1.6GHz notebook to use the E-350 dual-core integrated GPU with the same values ​​to achieve the following parameters: 3D Mark 2001SE 8341 (+ 11.5% compared to 6310 E-240 HD) 3D Mark 03: 5665 (+11, 5%), 3D Mark 05: 3561 (+7.4%), 3D Mark 06: 1997 (+1.3%), 3D Mark 11: 275 (+ 8.4% ).

Compared to the GPU faster Intel HD 3000, HD 6310 in the E-240 seems very old. In almost all benchmarks, Intel HD 3000 is 44 percent faster. Just for 3DMark 11, Intel integrated HD-3000 went through, it is not compatible with DirectX 11.

With these benchmarks will not tell you how the work feels subjectively on a laptop. 635 # ABD HP LH416EA can be used transparently for office applications and Web browsing also works well.

Listen to music or watching movies should not be a problem either, but HD video pushing this combination CPU-GPU to the limit pretty quickly. 1080P MKV videos are displayed as a slide show, instead of 25/30 frames per second, gets about 10 pictures reproduced. With the noise in the background is FullHD video playback not available with the HP 635 # ABD LH416EA.

The motto of this computer is "trying to take it slow." Different applications running with the parking brake engaged, and if you load more programs, this effect is noticably increase.

Hitachi is a hard HTS723232A7A364 storage for this system that gives 320GByte with 16MByte cache and 7200 RPM. Measure the average transfer rate with HD Tune Pro scored only 66.7 MB / s. The rate broke managed 119.5 MB / s, with a relatively high CPU utilization of 19.2 percent.

Transfer rates are lower than expected values ​​for the rotation of 7200 RPM hard, the results in more detail the same as the hard drive and 5400 RPM.

Game Performance
Playing games with the HP 635 LH416EA # ABD is limited. The graphics and GPU-intensive games or were unplayable or less pleasant. Wait an eternity, "Mafia II" For example, we found only 5 frames per second (fps). "FIFA 11" runs more than 55 fps in low resolution (800x600), but higher resolutions, the gameplay has dropped to zero. The launch of "3 Drift" has always been rewarded crash.

But many games pre-installed flash means you can use HP-635 as a gaming console anyway. More than 20 games in progress and 99% have installed the factory, after clicking the game icon, an automatic installation unpack the game and it can be played indefinitely. The selection consists of mind games, action games and simulations that work perfectly on material HP635.
