HP Envy TouchSmart 4-1102sg Ultrabook Review

A notebook with a touchscreen - that's still something unusual today (but not for long). But the HP Envy TouchSmart 4-1102sg isn't relying on this feature to make laptop owners envious. The manufacturer is also combining powerful speakers, a clever cooling system and thoroughly respectable inner-workings to make the device truly remarkable. ASUS G73SW-A1 charger

We'll see if owners of the Acer Aspire S7, the Asus VivoBook S400CA or the Sony Vaio SVT-1312V1ES really do have something to envy.

Case

Brushed metal is often a magnet for fingerprints - that's not the case here. That means the lid never looks smudged. Upon opening it, the screen stays true to the "black" color scheme on the outside surfaces, while around the black keyboard, silver is the dominant color.

At 2.1 kg (4.6 lbs) the device doesn't feel light, which is partly the fault of the screen's hard glass surface. With dimensions of 340 x 23 x 240 mm the device isn't exactly small either (14 inches). Asus A42-G75 charger

As is unfortunately common among most ultrabooks, you sacrifice user upgradeability and you are stuck with the default battery and other (normally user replaceable) parts.

Performance

Even if the device for review has exciting features at its command, you can't neglect the hardware behind it. The computing power is drawn from classic ultrabook components - an Intel Core i5-3317U and the Intel HD Graphics 4000. They are supported by a capacious 8 GB DDR3-SDRAM of working memory. A hard drive combination of a 500 GB HDD and a 32 GB SSD cache is also installed.

Processor
Intel Inside - in this case an Intel Core i5-3317U with the Ivy Bridge architecture. This runs with a base clock rate of 1.7 GHz, but the turbo theoretically provides clock rates of up to 2.6 GHz.

In the Multicore test with Cinebench R11.5, the review candidate lies at the same level as the Vaio SV-T1312, but behind the Acer Aspire S7 and the Asus VivoBook S400. In the OpenGL test, however, it triumphs over all three. When the devices are compared using Cinebench R10, the Envy doesn't do quite so well in the CPU tests - but for this chip it's at the expected level.

In the stress test the CPU stays at the clock rate of 1.7 GHz for the time being. First when the additional cooling reserves are freed via increased fan activity, the device jumps up to a maximum clock rate of 2.3 GHz. That would be a satisfactory result - if it weren't for the consistent throttling of up to 1.4 GHz due to the rising temperatures. But since all the benchmarks are at the expected level, restrictions due to throttling aren't forecasted with everyday use.

System Performance
The Envy gets the same number of points (4660 points) as the Sony Vaio SVT-1312V1ES in the PCMark 7 test. The Acer Aspire S7 outdoes them both (5020 points), but they bowl over the Asus VivoBook S400 (2823 points). Even the firm's own Envy 6-1000sg (which doesn't have a touchscreen and therefore isn't part of the competition) can't reach this score with 3529 points.

Storage Devices
Not one, but two hard drives are built into the device - though only one is available for active use. The passive SSD with 32 GB of space serves as cache which facilitates quick booting and fast access to recently started programs under Windows 8.

The conventional HDD is 500 GB and runs at 5400 rpm. In regards to the test with HD Tune, you shouldn't be fooled by the short-term power peak of 302.3 MB/s - the SSD jumps in for a moment. As it continues to operate, the write speed stays continually under 100 MB/s with numerous lows of about 1 MB/s.

Graphics Card
As is so often the case with notebooks containing an Intel processor, an Intel HD Graphics 4000 takes the role of the graphics card. Other models in the series like the Envy 6-1000sg (Intel Core i3-2367M as processor, no touchscreen) have their own graphics cards at their command - in the stated example, an AMD Radeon HD 7670M. The Envy Touchsmart isn't granted this luxury.

The 3DMark 11 performance test shows where the device stands in relation to similar devices and what their respective graphics cards can achieve. At 606 points, the Envy Touchsmart outpaces both the Asus VivoBook S400 (559) and the Sony Vaio SVT-1312V1ES (561 points, each with the same CPU/GPU combination). Thanks to its own GPU, the Envy 6-1000sg comes up with almost double the score at 1,172 points.

Gaming Performance
Just because it has a touchscreen doesn't mean you're restricted to playing Angry Birds. That's confirmed by the test with Anno 2070 and Diablo 3. The construction simulation and the Hack 'n' Slash games at their lowest settings run at a smooth 60 and 80 fps respectively. But that changes as soon as the graphic detail level is raised. With Anno 2070, the frame rate is cut in half at mid-detail settings; with Diablo 3 it slides down even further. At a high level of detail, neither of the two titles is playable.

The Envy isn't a real gaming laptop, but you can still enjoy fluid gameplay at low graphics settings, provided you're playing games with moderate hardware demands.

Emissions

The dynamically regulating fan continually provides the quietest background sound possible for a laptop: less than 31-33.9 dB without any appreciable load. Under mixed load the volume remains low to start with and only under full load do you hear clearly audible noises (up to 46.7 dB). In order for it to reach that point, quite a bit has to be demanded of the device. In practice you'll usually be confronted with a quiet, albeit softly audible device.

Temperature

In idle mode the temperature gauge doesn't cross the 30 degrees Celsius mark on the top side of the device. On the bottom, however, it does reach up to 34.1 degrees Celsius. The highest temperatures are measured in that same spot under high load. Up to 62 degrees Celsius are recorded - so to put the device on your lap under full load isn't a good idea, but for more practical Internet browsing or Office, use there isn't a problem.

The stress test (FurMark and Prime95 run for an hour) reveals how the temperatures inside the device can develop. The CPU reaches up to 77 degrees Celsius before the cooling finally fulfills its purpose. Working, first at full performance, the CPU temperature sinks to 68 degrees Celsius. Here a cooling system that jumps in to help a little more quickly would be ideal - but once the system's started running, the CPU stays relatively cool.

Speakers
Alongside the stereo speakers over the keyboard, there is an internal subwoofer. This combination increases the sound quality to an extent, but the "Sound by Beats" isn't really convincing. The only noteworthy thing here is the constant sound stability at high volume. Where cheaper speakers would weaken, you still hear clear sounds here. Although we are talking about better laptop speakers, they're no competition for external speakers or headphones. Asus C22-UX31 charger

Energy Usage
The device proves to be rather power-thirsty if you take a look at its power usage. An average usage of 10.8 watts in idle mode is usually undercut by other ultrabooks.

Also, under load, the average usage of 36.5 watts lies at the same level where other devices reach their maximum. But the power supply provides the necessary energy.

Although the battery only has 4 cells, they provide the laptop with energy for quite a long time. This review unit doesn't reach the level of the Sony Vaio SVT-1312, but a maximum battery life of 7 hours and 27 minutes is satisfying.

With everyday internet surfing, a fully-charged battery lasts 5 hours and 45 minutes; DVD playback with the external drive sinks this value to 3 hours and 12 minutes. The BatteryEater Classic Test reveals to us that the battery holds out at least 1 hour and 44 minutes.

When it comes to the features offered by the HP Envy TouchSmart 4-1102sg we're talking about a powerful mix. The touchscreen, the included external DVD drive and the speakers with a subwoofer lift the notebook distinctly above other media-laptops.

Whether the touchscreen really is a selling point depends on your own requirements for a mobile device. For those who find laptops too cumbersome and tablets too inflexible, here is an interesting balance. Unfortunately, the solution offered here brings disadvantages too. How sensible it is to buy a notebook with a touch display is therefore dependent on your own expectations.

At about 1000 Euro (~$1325) the device isn't cheap, but certainly exceptional. Anyone who is looking for a clever notebook that isn't for work purposes should definitely take a look at the HP Envy TouchSmart 4-1102sg.
