Power Usage

There’s a lot of performance on tap in the Xbox One X, which never comes with no strings attached. Like the Xbox One S, the APU inside is built on TSMC’s 16 nm FinFET process, which should help keep power usage under control. In addition, the Xbox One X is outfitted with a power supply that Microsoft equates to an 80 Plus Gold unit, which means it should be 90% efficient at 50% load with a 115 V source, and there shouldn’t be too much extra power wasted from the PSU converting AC voltage.

There’s several scenarios we tested for power usage:

Off – Xbox One X is powered off in Energy Savings mode, which means standby mode is disabled.

Standby – Xbox One X is powered off in Instant-On mode, which allows background updating and voice activation enabled (if supported).

Idle – Ethernet connected, no disc in the drive, system idling at dashboard.

Load (UHD BD Playback) – Ethernet connected, UHD Blu-Ray disc in the drive playing Planet Earth II, compared to The Hobbit on Blu-Ray on the original Xbox One.

Load (GoW4) – Ethernet connected, no disc in the drive, playing Gears of War 4 in UHD/HDR.

Load (The Wolf Among Us) – Ethernet connected, no disc in the drive, playing The Wolf Among Us in FHD SDR.

We’ve been able to compare against the original Xbox One, although not the S model as we didn’t have one on hand. The Wolf Among Us was chosen as an older game which caps at 1080p and SDR, and Gears of War 4 shows the power draw at full 4K HDR rendering. The comparison against the original for this game will of course be for the 1080p version though, since that’s the max it supports.

Power Consumption Comparions
Total System Power Energy-Saving Instant-On Idle Load (UHD BD) Load (GoW4) Load (The Wolf Among Us)
Xbox One < 2W 14.2W 53W 80W 107W 102W
Xbox One X < 1W 10W 56W 64W 172W 101W

As with the original Xbox One, when Instant On is disabled, the console is practically fully off. There’s a small amount of draw, but overall, not very much. Most people that use the console are going to likely want it in Instant On mode though, so games and the console can update while the system is off, as well as to provide a much quicker startup time, and games can remain loaded in RAM. In Standby mode, power draw is reasonable at 10 W, which is lower than the original console when it first launched. It’s still a fair bit of power, but when you factor in that it needs to keep 12 GB of GDDR5 memory powered up (among other things), it is not unreasonable to expect this amount of power draw.

Idling at the dashboard draws around 55 W, and to add to that, most non-gaming tasks don’t add very much to this total, if any. If you’re using your Xbox to passthrough HDMI from a cable box, it will take this same power draw. Maybe this would be an impossible pipe dream, but it would be nice to see the Xbox One also pass through HDMI when it is in Standby mode.

Playing back a UHD Blu-Ray (standard Blu-Ray on the original Xbox One) was a tiny bit higher than idle, which is good to see. Some of the draw would be the disc drive itself, but a lot of the playback would be offloaded to fixed function hardware in the media block so it’s not surprising to see it so close to idle.

Clearly gaming on older Xbox One games is not much of a chore for the Xbox One X, since the power draw is only about 50 W over idle. But, when gaming with an Xbox One X Enhanced title, such as Gears of War 4, the power draw jumps significantly to 172 W as the peak observed. This is quite a jump over the original console, and makes the cooling system, which is barely audible even under these loads, even more impressive. Compared to a high-end gaming PC though, the power draw is quite a bit less.

    It's outside of Zelda and Mario that Nintendo has troubles. There are plenty of good games on the other consoles and PC. Reply

    How about Great Games with a metacritic score in the upper 90's? I can play only so much GTA V. Reply

    I have a switch and both those games. They're a lot of fun. Like scbundy said, there are plenty of great games on other consoles and PC. Your comment is about as random as the one I replied to. Reply

    Yes.. But the topic is XBox One X. Where is the must have, totally engrossing, ground breaking title that makes an XBox One X a must have? Reply

    Oh I agree. Microsoft has an exclusives problem. I was just saying Nintendo is on the opposite side. Their 3rd party titles have been an issue for some years now, they ONLY have exclusives. Reply

    From the get go they said there would be no exclusive game for the Xbox One X errr XBOX. There are a couple games that can take advantage of the increased specs out already and about 130 patched. No one complains about this when they revised the PS4 as the Pro don't have any. Reply

    No that's not the point. The point is the Xbox console itself has very few exclusives. Not the X model specifically. There are games on the PS4 that do not appear anywhere else. Microsoft doesn't have that as all their titles are now on windows. Nintendo doesn't have 3rd party support and only has first and second party exclusives and a couple others here or there, but they are missing a large percentage of the 3rd party releases so the library is sparse.

    My sentiments exactly. There's nothing driving me to get an Xbone when a huge chunk of its titles are available on a PC (and often for less) let alone spend $499 to open One Xbox One X Box and find a console that outstrips an RX480 but still can't even hold 1080p60 in a Telltale point-and-click game (LOL) Reply
  • Manch - Tuesday, November 07, 2017 - link

    Yeah, you can't build a PC with similar spec/perf for that price. As far as the Tell Tale game goes, the dev needs to fix it as there is NO reason why it shouldn't run smooth. Other telltale games don't have this issue. Cant blame that on the XBOX. Reply

    No, you're missing the point. The OP wasn't talking about XBOX one games in general. He was bitching about there not being any XBOX One X exclusives. Reply
