Gigabyte P55W v5 Notebook Review

Sascha Mölck (translated by Liala Stieglitz), 02/20/2016

Enduring. There are no obvious performance gains in Gigabyte's gaming laptop when compared with the predecessor. However, the new Skylake processor leads to a considerably better battery life. Furthermore, a fast NVMe SSD is also on board.

For the original German review, see here.

As the name suggests, we are facing the fifth version of Gigabyte's P55W. Gigabyte relies on the same casing as in the precursor for its P55W v5. Consequently, the differences between the laptops are only minor. However, there are differences in terms of technology. Rivals of the P55W v5 include laptops such as the Schenker XMG P506 and the MSI GS60 6QE. Basically, all devices listed in our Top 10 Lightweight Gaming Notebooks can be considered rivals.

Since the P55W v4 and P44W v5 feature an identical build, we will not go into details about casing, connectivity, input devices or speakers – unless there are differences. The relevant information can be found in the review of the Gigabyte P55W v4.

What's new?

  • A Skylake processor replaces the Broadwell model

  • An M.2 connector is found in place of the mSATA slot

  • One USB 3.0 port makes way for a USB 3.1 port (Type-C)

  • DDR4 working memory instead of DDR3 RAM

The P55W v5 is equipped with the same screen as its predecessor. The rates differ marginally, which is normal. Two identically built panels never correspond one hundred percent. The screen offers a good contrast and only mediocre brightness. Positive: PWM flickering is never an issue.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9524 (minimum: 43 - maximum: 142900) Hz was measured.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
27 ms ... rise ↗ and fall ↘ combined↗ 7 ms rise
↘ 20 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 54 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.3 ms).
       Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 18 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 64 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (40.3 ms).

Performance

Gigabyte's P55W v5 is a 15.6-inch gaming laptop. It renders all up-to-date games smoothly. We cannot state an exact price for our review sample since it was not listed in price search engines at the time of testing. It will probably be priced at approximately 1600 Euros (~$1781).

Processor

The biggest innovation of the P55W v5 compared with its predecessor is the new CPU generation. As mentioned above, the Broadwell processor has been replaced by a Skylake model. To be precise, a Core i7-6700HQ is installed in Gigabyte's laptop. It is a premium-range model that looks impressive in all common application scenarios. It is not one of the frugal ULV processors (15 watts TDP). A TDP of 45 watts reveals its relationship to standard mobile processors. The CPU clocks at a base speed of 2.6 GHz, which can be boosted to 3.1 GHz (four cores), 3.3 GHz (two cores) and 3.5 GHz (one core) via Turbo. The Turbo is also fully utilized in AC mode. It is not used as intensely in battery mode. The processor then only clocks at 2.9 to 3.5 GHz (single-thread) and 2.9 to 3.1 GHz (multi-thread).

The P55W v4 came with the Broadwell predecessor (Core i7-5700HQ) of the processor installed here. This calls for a direct comparison. A clear winner could not be determined in the CPU tests that we performed. Sometimes the one and then the other processor had the lead. It can be said that the P55W v5 delivers the same CPU performance as the P55W v4. However, the new Skylake processor improves something else, as we will see later.

System Performance

A super-fast solid-state drive and a strong processor ensure an overall fast-running system. Accordingly, the PCMark scores are very good. Despite the much faster SSD, the P55W v5 does not stand out from its predecessor. This is not very surprising since there is no subjective speed difference, which the PCMark 8 Home tries to simulate. An advantage of the PCIe/NVMe technology is noticed vaguely in loading processes, for example when loading computer games. It will hardly be possible to increase the system performance. Only installing a second working memory would be make sense.

Storage Devices & Memory Card Reader

The system drive is a Samsung SSD in M.2 format (type 2280) with a capacity of 128 GB. Approximately 90 GB is available for the user. The rest of the storage is reserved for the Windows installation and recovery partition. It is an NVMe model that is connected via PCI Express. Consequently, the P55W v5 delivers superb transfer rates. Although the solid-state drive offers a total of only 128 GB, the laptop has plenty of storage. A conventional 2.5-inch hard drive provides games with the required capacity. The 2.5-inch model spins at 7200 revolutions per minute and has a capacity of 1 TB.

The memory card reader is neither super-fast nor particularly sluggish. A maximum transfer rate of 76 MB/s is achieved when copying large data blocks. The P55W v5 transfers 250 JPG images (approx. 5 MB each) at a speed of 47 MB/s. We always test the card reader with our Toshiba Exceria Pro SDXC 64 GB UHS-II reference card.

Graphics Card

Nothing is new in terms of GPU. The new model is also equipped with a GeForce GTX 970M. The GPU supports DirectX 12 and clocks at up to 1038 MHz. 3072 MB of GDDR5 VRAM supports the core. Gigabyte should have improved here. 3 GB are rather scanty for a device of this performance category. There are laptops with weaker GPUs that have 4096 MB graphics memory. The 3DMark scores are roughly on par with those of the predecessor.

Gaming Performance

Gigabyte's P55W v5 definitely belongs to the gaming laptop category. It renders every computer game smoothly. Most games even allow using the screen's native resolution (1920x1080) alongside maximum graphic settings. Reducing the pixel count and/or quality level will only be necessary in a few games. No major frame rate differences are observed between the Broadwell and Skylake model of the P55W.

Emissions

System Noise

The fan in the P55W v5 permanently spins at a consistent and low speed while idling. The 2.5-inch hard drive's noise is primarily heard. The cooling clearly speeds up during load. A noise level of 49 dB(A) was reached in the stress test. This rate is acceptable for a laptop from this performance category. The fan slows down quite quickly after prolonged load.

Temperature

Stress test
Stress test

The P55W v5 performed the stress test (Prime95 and FurMark run for at least one hour) differently in AC and battery mode. The CPU clocked at 1 GHz and the GPU at 200 to 700 MHz for about 10 minutes in battery mode. They then throttled to 800 MHz (i7-6700HQ) and 200 to 250 MHz (GTX 970M). Throttling did not occur in AC mode. The processor clocked at 2.7 to 3 GHz, and the graphics core reached speeds of around 1000 MHz. Only the casing heated up moderately during the stress test. Although 50 degrees Celsius (~122 degrees Fahrenheit) was exceeded on some measuring points, we have seen laptops based on a comparable configuration that reach considerably higher temperatures.

Energy Management

Power Consumption

We measured an idle power consumption of up to 17 watts. This is acceptable for a laptop of this performance category. The energy requirement climbed up to 152 watts in the stress test. The power supply can deal with that: Its nominal output is 180 watts. The consumption is much lower in gaming routine. Rates of approximately 81 watts (+/- 10%) can be expected here.

Battery Runtime

The P55W v5 surprised us positively in terms of battery life. The energy efficient Skylake processor is noticed here. Some ULV office laptops do not achieve the rates we measured. Gigabyte's laptop managed a runtime of 5:48 hours in our real world Wi-Fi test. Thus, it lasts almost 2 hours longer than its predecessor. We simulate the load needed for opening websites via a script. The "Balanced" profile is enabled, and the screen's brightness is set to approximately 150 cd/m². The laptop finishes the video playback test after 5:32 hours. We run the short movie "Big Buck Bunny" (H.264 encoding, 1920x1080 pixels) in a loop here. The radio modules are disabled, and the screen's brightness is dimmed to 150 cd/m².

Verdict

In review: Gigabyte P55W v5. Review sample courtesy of Gigabyte Germany
In review: Gigabyte P55W v5. Review sample courtesy of Gigabyte Germany

Gigabyte's P55W v5 is a 15.6-inch gaming laptop. The installed Core i7 processor provides enough computing power for all common application scenarios. The GeForce GTX 970M renders all up-to-date games smoothly. A lightning-fast NVMe SSD ensures a fast-running system. Thanks to the existing 2.5-inch hard drive, storage capacity will not get tight. Both storage devices could be easily replaced with higher-capacity models. Although the P55W v5 does not have a maintenance hatch, the base tray is easy to replace. The good keyboard is surprising in a gaming laptop. The same is true for the long runtimes in our real world battery tests. The matte Full HD IPS panel pleases with stable viewing angles and decent contrast. However, its brightness could be higher.

Gigabyte primarily upgrades its P55W v5. The modifications and innovations (NVMe, DDR4 RAM, USB 3.1, and Skylake CPU) prove reasonable.

However, Gigabyte should have followed this path more consistently. For example, a DisplayPort would have been desirable and more graphics memory would also be appreciated. Perhaps Gigabyte will take up these points for its P55W v6.
