XMG is the gaming sub-brand of German laptop maker Schenker. And within the XMG range lies a choice of three levels – Advanced, Core and Pro – which correspond to the entrylevel, midrange and flagship series. So the XMG P505 is a gaming laptop from the top tier that Schenker says can deliver unless you want to step up to the Ultimate Series. This takes a desktop-class CPU and all the trimmings, making it more of a fire-breathing desktop replacement PC; less of a notebook you’d want to place upon your lap. This 15in gaming laptop serves as a platform to host nVidia’s newest 900 Series mobile graphics processors, namely the GeForce GTX 965M, 970M and 980M. We tested a configuration with the top 980M, allied with the laptop motherboard’s single choice of CPU, an Intel Core i7-4720HQ running at 2.6GHz. This chip packs 6MB cache and can Turbo up to 3.6GHz.

Configurations and Options
The starting price for the XMG P505 is £891, although at this price you don’t get any internal storage, let alone an operating system to install it on, nor any wireless connectivity. Visit the laptop’s product page and you’ll find that Schenker UK has a base model with a 500GB hard disk and budget 11ac Wi-Fi card for a price of £939, although you’ll still need to pay £65 for Windows. Memory is fully configurable, from a single 4GB RAM card of Crucial Ballistix Sport, up to 32GB Kingston HyperX Impact. The given options are for 1866MHz clock memory, higher than Intel’s official specification for this processor of 1600MHz. Schenker UK tells us that even higher-clocked RAM can be used, up to 2133MHz, although this isn’t stable.
We specified 16GB of Crucial memory. There’s a total of four slots for SO-DIMM memory modules, with the preinstalled RAM positioned on the reverse side of the motherboard. There’s a way in through the keyboard, to swap this out without a lengthy teardown of the entire machine. You can also add two more memory cards easily to slots on the top side of the motherboard when the bottom plate is removed.
The standard 15.6in screen is 1920x1080 resolution, IPS technology, and finished with a matt anti-glare coating. You can also trade up to a 4K UHD panel of 3840x2160, although since even the world’s finest GPUs for laptops struggle at four-times the full-HD resolution, we suggested a 2880x1620-pixel panel as the best compromise, driven by the top GTX 980M graphics processor with 4GB of GDDR5 video memory. Storage options get very interesting, as the P505 can accept up to two traditional SATA drives, either 2.5in hard disk or SSD up to 9.5mm thick each, plus two M.2 form-factor drives. One of the latter can be a PCIe-attached flash drive, using four lanes of PCIe 2.0, while the other is fixed to a SATA bus only. But this SATA-only M.2 card slot can also potentially take a cellular data modem, which is why chassis manufacturer Clevo includes a SIM-card slot on the
laptop’s side. Our sample was configured with a single drive, a Samsung XP941 PCI3 2.0 x4 card with 512GB capacity. For wireless communications, we added the option for Qualcomm Killer dual-stream 802.11ac. Despite the size of the laptop, there’s no third antenna in the chassis to allow a full 3x3 MIMO Wi-Fi card.

Build and Design
Like most customizable laptop designs, Schenker relies on pre-built and semi-stuffed chassis from Taiwan maker Clevo, and here the XMG P505 is using a Clevo P651G case and display assembly. This case is a heavy-duty chunky construction, satin finish black comprising an aluminum lid back and top deck area, and a black plastic bottom on the model we tested. Ironically, if you choose the cheapest nVidia GTX 965M graphics, you should get a metal bottom plate, too. The plastic bottom is reserved for models with GTX 970M and 980M, which require a more powerful cooling system. Cooling is undertaken by three fans, two on the GPU and one for CPU. There’s no built-in optical drive, and like many modern laptops the battery is not designed to be changeable by the user. Inside is a lithium-ion battery pack with 60Wh energy capacity. In our standard video-rundown test, this let the P505 survive off the mains for three hours 11 minutes.

The laptop weighs a not ungainly 2.59kg in this configuration, but you’ll need to factor in another 1.05kg for the 180W mains power supply should you need to travel far. The keyboard, track pad and display are all of a very high quality, with special mention for the unusually precise trackpad with its two real buttons, and the first-class IPS display on the model we tested
Ports and Components
With such a capable graphics processor under the bonnet you may be inclined to connect additional display, made easy by the choice of two Mini DisplayPort v1.2, which can channel up to 3840x2160 pixels at 60Hz; and an HDMI 1.4 port good for 2560x1600 (or higher to 4K UHD but with slow refresh rate). Three USB 3.0 ports are joined by a fourth on the backplane that doubles as an eSATA port. For audio there are three 3.5mm jack sockets, designed for S/PDIF, mic input and headphone output. Sound quality from the built-in stereo speakers with 2W amplifier is perfunctory, but sufficient for lo-fi music playback.

Performance
The Core i7-4720HQ is a popular choice for gaming laptops at the moment – four out of six machines in our last group test all used the same Intel chip. Our benchmark results for the P505 followed the scores from those laptops, returning 3545 points in Geekbench 3, and 13,336 with eight Hyper Threading virtual cores engaged. Cinebench 11.5 scored this laptop with 1.58 points single-core, and 7.38 points multi-core, which is at the top end of scores we’ve seen with laptops using this quad-core chip. Similarly, Cinebench 15 returned figures of 139- and 681 points, which is just above results of comparable gaming laptops. For OpenGL graphics performance, version 11.5 played at 59.5fps while Cinebench 15 rose to 90fps. The latter score is good, but some way behind the 108fps we saw from the Gigabyte P37X using the same CPU/GPU combination.

PCMark 7 rated the P505 with 6217 points, an exceptionally high score for any PC. The PCMark 8 Home results of 2771 (conventional) and 3276 points (accelerated) were more disappointing, when the Gigabyte P37X scored 3300 and 4049 points in the same test. The Work results of 3018- and 4328 points were also some way behind the 3478- and 5156 points of the latter gaming machine sporting the same Intel and nVidia parts. It’s worth mentioning that the Gigabyte resolves its performance storage in a different way, using two mSATA SSDs in RAID 0 rather than a single PCIe x4 SSD, which give broadly the same level of performance
Storage
Thanks to the Samsung XP941 PCIe solid-state drive, the P505 we bench marked was capable of very fast data transfers, up to 977MB/s sequential reads in our tests. Sequential writes were close at 891MB/s, and high speeds were also recorded for 512kB size data, 644- and 778MB/s respectively for reads and writes. In the important 4kB random read/write tests we saw speeds of 24- and 76MB/s respectively for reads and writes, rising to 326- and 275MB/s using a 32-depth queue. These are great results, unheard of from a single drive, though still behind what we’ve seen from a RAID’d pair of SATA SSDs.

Graphics
As we found with the last gaming laptop using the top nVidia GeForce GTX 980M graphics processor, it is possible to play graphics-heavy action games up to their highest detail, and usually even beyond full-HD 1920x1080 resolution. Our simplest test for gaming laptops of Batman: Arkham City at 1920x1080 and High detail was quickly dispatched at an average framerate of 95fps. This fell to 89fps at Very High and 80fps at Extreme detail settings. Given the nVidia chips clear fluency, we rose resolution all the way to screen native 2880x1620, where the game averaged 72fps at High detail and only fell to 62fps at the Extreme setting. Tomb Raider 2013 sped by with even greater ease, at 217fps with Normal detail and full-HD screen resolution. We ratcheted up the detail to High (150fps) and Ultra (111fps) before hitting Ultimate and a still remarkable 76fps. Having proved its mettle, we again went up to native ‘3K’ panel resolution. This time Tomb Raider averaged 79fps with High detail, 57fps at Ultra and an accomplished 41fps at maximum Ultimate preset. Presented with Metro: Last Light, the XMG P505 could play at an average frame rate of 108fps in our standard full-HD High test, tumbling to 36fps at our top Very High settings.

Display
The 2880x1620 IPS display available to this laptop is an unusually fine example of the technology. In lab measurements it may not look too remarkable, its 94 percent sRGB coverage missing the full coverage some IPS panels provide, and contrast ratio reaching a middling best of 510:1. Colour accuracy was good but again nothing exceptional with Delta E average of 1.34. What impressed with this Panasonic-made display was the subjective impression of image quality. Despite the measured results, black looked very deep and inky, type and images were incredibly detailed; and, of course, with clear viewing angles as wide as the screen.

Verdict
The Schenker XMG P505 is a very accomplished game player, fuel led by its top-of-the-range nVidia mobile graphics processor. The Clevo platform to support this is standard chunky games machine fare, although the all-up weight of around 2.6kg is modest by the standards of the breed. This laptop is distinguished by its premium IPS display, solid build and the graphics chip required to drive modern Windows games at their highest settings without fuss. And as a general PC, it feels commensurable quick, helped along by its 1GB/s-class PCIe solid-state drive.
