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.

    I wonder how it will stack up with a $500~ prebuilt PC/steam machine ... Reply

    Right now very favorably due to the high price of PC video cards. Reply

    Yeah people are asking 400 dollars Canadian for a USED gtx 1060 6gb. This is priced very competitively in Canada for sure, just 599.

    Sad a little about the lack of Ryzen, will affect future proofing, but this is so much better than the first xbox one.

    I imagine a custom Ryzen APU would be ideal, though as Jaguar has eight independent cores with their own FPUs, I don't think a 4C/8T replacement would suit... that would mean swapping out four real cores for four logical ones. Reply

    There is a strong case to be made for building an i3-8100 system for your living room instead of buying an Xbox One X, to get strong 60 fps support.

    But memory prices, gpu prices, and a Windows licence are all too expensive. 12GB GDDR5 must have cost Microsoft a pretty penny.

    You can get an OEM Windows Pro license for about $15. Or you can just install SteamOS. Even then, it's not easy to get it under $500. Best bet would be to find one on Craigslist or eBay for cheap and upgrade the video card and maybe the power supply. Reply

    None Sense, you can go on Ebay or Amazon and get slightly used, perfectly flawless, computer components from one generation ago and build something for $400 that would blow this out of the water. Not to mention you have to pay a special fee to play video games online, on top of the internet. Reply

    More so than most, I am leery about paying for used electronics as there isn't any way to measure how much use and abuse they have. In order to make an apples to apples comparison you really need to compare "Brand new PC" to "Brand new XBox One X". If you want to wait you can probably get a discount on a used XBox One X. Even so, building a system that can compete with this (which only works if you have the 4K TV) is going to be difficult even if you use "used" components. This is a very high quality device that will bring ultra hi-res 1080P games (all graphics enhancements) or 2160P games with frame rates between 30 - 60 fps. In many cases an enhanced 1080P game can look as good or better than a 4K game. If you're a high level gamer looking for the best the $499 is a bargain. Reply

    I think the Ryzen SOC would goes to the next gen instead. Reply

    Seeing how AMD seems to have a lock on console APU's/SoC's I would bet real money the next consoles will be based on Zen cores with a Vega GPU. Microsoft, Sony, and historically Nintendo, all seemed pretty comfortable working with AMD.

    Of course, the switch is obviously nVidia Tegra-based, so who knows about Nintendo...and if they will even make a performance console again...
