With SLI off (without overclocking), performance jumps to 115 fps, which is on a par with the MSI GT73VR and its GTX 1080 GPU. With SLI enabled, performance in Rise of the Tomb Raider was 95 fps.

If you look at the chart below, you’ll see that SLI made a difference in this game-it depressed performance. We ran Rise of the Tomb Raider at 1920×1080 using the Very High preset and in DirectX 11 mode. The hard truth everyone should know when considering an SLI laptop is just how many games ignore multi-GPU support. The Predator 21X is king of the hill, but its performance is a little handcuffed by the relatively low resolution we test at. In fact, dual GTX 1080’s probably don’t really get a workout until you’re playing games at 4K or running multiple monitors at low resolutions. Even though it was rendering 30 percent more pixels, the dual GTX 1080’s were still paying off significant dividends. Running Middle-earth at its native resolution and still overclocked, we saw the Predator 21 X actually spit out 198 fps, compared to 190 at 1920×1080. The Predator’s 120Hz G-Sync panel has a native resolution of 2560×1080 which is about 2.7 million pixels, vs. We run most of our real-world gaming tests at resolutions that most gaming laptops support: 1920×1080. Some of the lack of impressiveness is likely due to the resolution we set for this game. Everyone’s close enough, though, that the differences don’t matter much. (We suspect both CPU results were overclocked results, but we no longer have the laptop to check.) And just like with Cinebench R15, when you run the Predator 21 X in its Turbo preset, it’s clearly in front of the pack. On giant gaming laptops, it’s really no sweat at all.Īgain, the GT73VR pulls ahead slightly. On small laptops, this is a challenge for their cooling systems. Like Cinebench, Handbrake loves CPU clock speed and CPU thread and core count.īut unlike Cinebench R15, which runs in just a minute or three, Handbrake can take 45 minutes to run on a quad-core, and well in excess of an hour to run on a dual-core.

For this test, we take a 30GB 1080p MKV file and convert it using the Android Tablet preset.

Most people don’t do 3D rendering, though, so we also gauge CPU performance using the free and popular Handbrake encoder. Fortunately you get that with the Predator 21 X, which can bring on the GPU and CPU loads without sounding like a Huey chopper is taking off in front of you.įor the most part, quad-core laptops tend to pack group up in multi-threaded tasks but the overclock on the Predator 21X gives it a good step in performance. Today, people want their gaming as quiet as possible. Two years ago, loud and gaming went hand-in-hand. Gaming laptops have come a long way in just two years, and so have consumer expectations. Performance: Powerful, yet still relatively quiet You can easily access the hard drive and RAM from the top. Just remove one screw and carefully pull off the the personalized plate, and you can replace the hard drive (again, limited only to 9.5mm) and replace the RAM if you need to. But there’s also more hardware you can replace on the top. You already know about the two M.2 SATA slots under the bottom service door. The Predator 21X’s size lets it hold very high overclocks without sounding like an F-22 on afterburners. Unplugging the laptop would switch off the overclock and severely ratchet back the GPU clock speeds.

When there wasn’t a load on the Predator 21 X, the laptop would behave in a more civil matter.

But considering the Predator 21 X’s formidable power load, it’s probably safest to hit full stop rather than shove a 400-watt load onto the onboard batteries in a millisecond. For any other laptop, you’d expect it to switch over to the internal battery. We ran into one interesting behavior: If you push the GPUs hard running Furmark, with the CPU and GPUs overclocked, and then suddenly pull the plug, the Predator 21 X immediately cut power to the laptop.

Power consumption itself, for what it’s worth, generally sat in the 400-watt range under a graphically intense workload such as Furmark. For the sake of appearance and neatness, it’s a nice touch you’d expect of a premium machine. In a sign of how much thought Acer put into the Predator 21 X, the company includes a rubber stand for the AC adapters, emblazoned with the Predator logo and shaped in an X. The Predator 21X runs on two 330 watt bricks that can stylishly be held together using the included X-shaped rubber coupler. Both are identical, so there’s no specific order for plugging them in. Because no external bricks are available in sizes larger than 330 watts, Acer uses the old trick of slaving two 330-watt bricks together. As you can imagine, all of this hardware takes a considerable amount of power to run.
