How to convert a normal laptop into a Gaming pc

Ultrabooks are by far the most popular category of laptops, providing enough performance for everyday tasks in a compact, portable form factor you can carry between home and office. But there’s one crucial task that these thin-and-light machines are incapable of, and that’s hardcore PC gaming.

Most people looking to play games on their PC will examine a few options. Desktop PCs are the best choice from a price and performance perspective, but they aren’t portable. A desktop will require an external monitor and peripherals, and simply can’t replace what a laptop does.

Gaming laptops are a portable equivalent and surely they’re getting better, but for the most part they’re always larger and heavier than an ultraportable for a decent level of power; plus they tend to be pretty expensive.

A new option for PC gaming has started to appear over the last few years: external graphics boxes, which connect to a laptop and provide the power of a fully-fledged graphics card when you’re at your desk.

An external box will still allow you to carry around your favorite laptop on the go. A couple of options have hit the market so far, the proprietary Alienware Graphics Amplifier and the Razer Core. The problem with these is the outrageous pricing.

The Razer Core is particularly interesting because it’s compatible with many laptops via Thunderbolt 3, but costs a whopping $499.99 without a graphics card. This makes the total cost of external laptop graphics a very expensive proposition, especially if you want decent power from something like a GeForce GTX 1070.

This is where the new Aorus GTX 1070 Gaming Box comes in. It offers similar features to the Razer Core – it’s an external desktop graphics card enclosure that connects to laptops via Thunderbolt 3 – but costs $600 with a GTX 1070 included inside. The Razer Core with equivalent hardware will set you back at least $300 more.

The GTX 1070 Gaming Box is much more compact as well. Leveraging Gigabyte’s GTX 1070 Mini ITX OC along with a slimline 450W 80Plus Gold power supply. This does restrict upgradeability of the unit, but it keeps it small and portable.

At just 2.4kg heavy, you can pretty easily carry around the entire unit with the provided carry bag, and its small footprint is suitable for any desk setup.

I really like the design of the Gaming Box, with metal on all sides and large vents on the left and right. There’s even RGB lighting in there. On the rear you’ll find all the I/O: AC power in, Thunderbolt 3, four USB 3.0 ports (one supports Quick Charge 3.0), and all the display outputs from the graphics card, in this case DisplayPort, HDMI and two DVI.

Setting up and using the Gaming Box is extremely simple. To be honest I was expecting it to be less straightforward, but all you have to do is plug in the power cord, connect it to your laptop via Thunderbolt 3, let your laptop’s Thunderbolt 3 driver utility set up the unit with a few prompts, then install Nvidia’s GeForce graphics driver. That’s it.

From there, the Gaming Box works exactly as you’d expect. When running a game, it automatically switches from using internal graphics to the external GTX 1070, and passes the display signal back to the laptop’s display. If you hook up an external monitor, that works even better, with a small performance advantage. And of course, you can use the rear USB ports to attach your keyboard and mouse.

The unit is fully plug and play with no on/off switch. Plug in the Gaming Box, and the unit will automatically power up and your setup will switch to external graphics when required. Disconnect the Aorus Box and there’s a smooth transition back to using integrated graphics. And thanks to power delivery over Thunderbolt 3, the Gaming Box charges your laptop while it’s connected (where supported) with up to 100W of juice.

I was expecting to have some sort of struggle using this device for gaming, or some sort of plug and play issue, but that wasn’t the case at all. It worked perfectly with my Kaby Lake Lenovo ThinkPad X1 Carbon.

Oh and here’s a quick note on the noise and thermals produced by the Gaming Box. Under load the Box is pretty quiet, thanks to the large cooling vents on either side providing enough airflow such that the fans don’t have to spin up significantly. Unfortunately there is a bit of coil whine from the power supply, noticeable when the GPU is fully utilized. As for temperatures, the GPU sits comfortably at around 70°C under load, which is what you’d expect from this card in a desktop PC.

Gaming Performance

Before I get into performance specifics, let’s talk about the test setup. I used the Gaming Box with base level ultraportable hardware: a Lenovo ThinkPad X1 Carbon kitted out with an Intel Core i5-7200U processor and 8GB of RAM. Aorus says you wouldn’t want to game with any lower hardware, and I’d definitely agree, as this is pretty much the entry-level ultraportable experience.

The Core i5-7200U is particularly interesting here because it’s a two-core, four-thread 15W CPU clocked at 2.5 GHz with a boost speed of 3.1 GHz in both single- and dual-core modes. This isn’t a fast CPU by any stretch, in fact it’s slower than the Intel Pentium G4560 at base clock speed (3.5 GHz) which we recommend for budget PC gaming builds. As we’ll talk about later, the CPU can often run us into trouble.

For our testing, I first attempted to play a bunch of games on the ThinkPad X1 Carbon’s integrated graphics at the lowest possible settings to see if even a single game was playable. You’ll see those results in the table below, along with the performance I achieved at various quality settings when using the GTX 1070 Gaming Box instead.

Game Integrated Graphics GTX 1070 Gaming Box
Batman: Arkham Knight Didn’t launch at all 1080p Ultra no Gameworks: 77 FPS
1080p Ultra with Gameworks: 46 FPS
Battlefield 1 MP Crashed before loading 25-35 FPS hard CPU limit with 64 player MP
CS: GO 1080p Low: 20 FPS
720p Low: Barely 40 FPS
1080p Max: 100-140 FPS
1080p Low: 100-200+ FPS
Deus Ex: Mankind Divided 1080p Low: No more than 10 FPS
720p Low: At best, 20 FPS
1080p Ultra: 44 FPS
1080p High: 54 FPS
Fallout 4 1080p Super Low: 17 FPS
720p Super Low: 24 FPS

The Witcher 3 1080p Low: 11 FPS during intro
720p Low: 16 FPS
Horrible input lag so unplayable
1080p Ultra: 45-50 FPS
1440p Ultra: 43-47 FPS

As you’ll see in this list, a couple of games like Batman: Arkham Knight refused to play at all on integrated graphics, while others like Deus Ex: Mankind Divided and The Witcher 3 were unplayable even at 720p low settings. The only two games I’d consider playable were Sleeping Dogs and Tomb Raider, both games from around 5 years ago, and only when set to the lowest possible quality.

Aside from the unfortunate Battlefield 1 multiplayer result, the general experience provided by the GTX 1070 Gaming Box here is very good. It comfortably transforms the excellent ThinkPad X1 Carbon ultraportable – and similar Thunderbolt 3-equipped laptops – into a capable gaming machine. For the most part, the graphically intensive games I tested were playable at 1080p or even 1440p at high to ultra detail settings with respectable frame rates.

However, many of the tests ran into CPU bottlenecks thanks to the relatively weak Core i5-7200U. Often this left the GTX 1070 underutilized, so I’d expect you’d get a better experience with a faster Core i7-7500U, which has a 13 percent higher boost frequency. Even better results will be had with a quad-core CPU like the i7-7700HQ, though not many laptops without dedicated graphics use that.

Due to this CPU bottleneck and your expectations of gaming with a GTX 1070, I’m sure you have a number of questions about the Gaming Box’s performance, which I’ll try to address right now.

You’re probably wondering how the Gaming Box hooked up to an ultraportable compares to an actual gaming laptop with a GTX 1070 inside. I’ve run a few tests, and it seems that with a much faster quad-core CPU and no potential Thunderbolt 3 concerns, a GTX 1070 gaming laptop is around 30 to 40 percent faster on average, though this margin decreases as games are more GPU-limited.

A fully-fledged gaming desktop with an overclocked Core i7-7700K and a GTX 1070 inside will outperform the ultrabook plus Gaming Box combination by a larger margin, somewhere around 40-45 percent on average. And of course, games like Battlefield 1 multiplayer will actually be playable.

It’s also worth mentioning frame time performance. Throughout most of the testing so far, I’ve only been discussing average frame rates, which don’t illustrate how smooth the experience is with the Gaming Box.

Smoothness can vary a lot with the Gaming Box, much more than a gaming laptop or a gaming desktop, due to the inherent hardware limitations of ultraportables like the slow CPU, limited memory capacity and bandwidth, and so forth. Some games run smoothly for the most part, like Mass Effect Andromeda, Batman Arkham Knight and Prey, with only the occasional slowdown.

Other games like The Witcher 3 stutter more frequently, often when the CPU is bouncing around 100% utilization. These stutters are not something I’ve experienced on gaming laptops or desktops, so it’s something to note about external graphics solutions. In fact, here’s a frame time graph so you can see exactly what I’m talking about:

The large spikes in the above graph, recorded while playing at 1440p Ultra settings with no Hairworks, indicate noticeable stutter during gameplay.

Again, it does depend on the game, but just be warned that you may not get a smooth experience in every game with an entry-level ultraportable.
