Xbox Series X is a central component of Microsoft's future-facing gaming efforts, positioned as its flagship console headed into the next generation. Tailing the 4K-brandished Xbox One X, the elusive successor promises a generational shift akin to the original Xbox One debut in 2013. Development on the high-horsepower box remains underway, set to rival the Sony PlayStation 5.

While current reports allude to tiered Xbox consoles dubbed "Anaconda" and "Lockhart," Microsoft's public-facing efforts currently focus on one device. The console aims to achieve 8K resolutions, or 4K at up to 120 frames-per-second (FPS), complemented by ray-tracing, variable refresh rate (VRR) support, and more. Here's the full list of planned Xbox Series X specifications.

What do the Xbox Series X specs mean?

Xbox Series X Chip

At the heart of Xbox Series X lies a custom-designed CPU founded on AMD's Zen 2 architecture. Previously behind chipsets fueling the Xbox One family, the leading U.S. manufacturer extends efforts via its latest processor technology. The Zen 2 family touts improved performance and efficiency, with Xbox Series X poised to deliver four times the CPU power of Xbox One X. With the current Xbox flagship heavily reliant on its GPU advancements, Scarlett's revamped system-on-chip (SoC) helps alleviate a primary bottleneck.

A Navi-based GPU flanks the Zen 2 brains, powered by AMD's latest wave of RDNA graphics technologies. It assembles a formidable SoC for next-generation gaming, clocking in at 12 teraflops, indicating its ability to process 12 trillion floating-point operations per second. In short, that means a console vastly superior to anything on the market (including the 6TF Xbox One X) and on track to surpass some of the best graphics cards like the GeForce RTX 2080.

The Xbox Series X also comes with the added capabilities of "hardware-accelerated" ray tracing. NVIDIA has already drawn eyes with its GeForce RTX GPU lineup's real-time ray tracing capabilities, and both Microsoft and Sony are set to follow suit for more realistic lighting.

Xbox Series X Storage Expansion

Microsoft's added commitment to NVMe solid-state drive (SSD) storage is an understated and vital final inclusion under Series X. Microsoft has cooked up a custom setup tailored to the console, with faster overall storage meaning huge gains, drastically slicing load times and installations. Seagate has also aided on the production of proprietary SSD memory cards, enabling users to expand storage, while meeting the speed requirements for Xbox Series X optimized titles. However, older experiences for Xbox One, Xbox 360, and the original Xbox can use a regular external drive, powered by USB 3.2.

The result is a future-facing console built on strong foundations, already pushing the higher end of the PC market. Paired with the benefits of SSD storage, Xbox Series X establishes a promising baseline for the next generation of consoles.

Xbox Series X is slated to launch in the 2020 holiday season, with pricing still to be confirmed.

  • Hello, just to clarify about the ram, it's GDDR6, not DDR6. But it could also have DDR4 since it loads up apps too.
  • What's the difference?
  • Well first DDR6 doesn't exist right now. In fact DDR5 (that is a 5) won't arrive until next year. But GDDR6 (essentially all memory with the G in front) are designed to work specifically with graphic type of work loads. They have a higher bandwidth and wider memory bus. GDDR has a lower power and higher heat dispersal requirements (easier cooling requirements). GDDR is designed around the need for processing large amounts of repetitive and simpler workloads hence a larger bit bus is used to prevent bottlenecks. GDDR is not better or worst. It is just designed for a different type of workload.
  • Thanks for that explanation, I didn't realize there was actually differences in graphics RAM vs normal memory.
  • It might be worth mentioning in the article that Navi GPU is confirmed by Amd at E3 2019 in their presentation that it cannot do Ray Tracing. So there has to be a piece of the puzzle that MS isn't sharing with us at this time. Rumours are PS5 is using AMD Hybrid. Software Ray Tracing. A very far cry from hardware level Ray Tracing. So it will be interesting to find out how MS is doing ray tracing at a hardware level.
  • The rumour is that AMD has a Navi 20 chip on its way that will handle ray tracing (as opposed to the Navi 10) and that the upcoming consoles will be using modified versions of that chipset.
  • No that's not the Case. AMD confirmed for the generation of Navi they only have software shader Ray Tracing. The next Gen GPU architecture after Navi will have hardware level Ray Tracing. But only for 'select light sources'. AMD full scene Ray Tracing will only come from the cloud even further down the line. This digital Foundry video on the AMD conference will dispel alot of silly Rumours out there about what next Gen consoles can and can't do. Hardware level Ray Tracing is only going to be possible on next Gen machines via a separate chip custom designed for that purpose. Otherwise it will be software level shades. And that's basically it.
  • That was in 2019 and Microsoft has already started that they are using a separate chip for hardware Ray Traceing.
  • As an aside, if either of the upcoming consoles actually maintain native 8K support that doesn't fluctuate, doesn't utilise tricks, I will eat a shoe. I'm not even expecting either system to offer native 8K at all for gaming, only video, but we will see.
  • time to do articles on how to replace your hard drive in your old xbox one and xbox one x to ssd now :D
  • Also worth noting, Digital Foundry using the video showing the motherboard at E3 2019 confirm 24 GB of ram on the board. Unless the video isn't showing the actual Scarlett motherboard at the MS conference.
  • Would've been handy to keep the original article date and add updated 14th Dec 2019 date alongside given there are comments from July 2019 lol. Since Ryzen 2nd gen supports PCI-E 4.0 that NVME storage is going to need a decent amount of cooling as PCIE-4.0 NVME storage is known to get rather toasty. On the flipside it would mean crazy fast read and write speeds this could literally eliminate load times entirely - depending on game optimisations of course. I'm curious what fps and frame times they are targetting for 8 k resolution... hmm... 🤔.
  • Why with the 8k..
    No one has 8k TVs, most people don't even have 4k TVs.
    Put those performance resources towards something better
  • Lol!!! Gotta love the blanket statements. Some people in the world have 8K TVs. Samsung has one right now for only $2,200! You really think NO ONE bought this set??? Also, "most" people don't have even 4K sets? Where are your numbers here? 4Ks are down to below $500! If anything the number is growing at a steady pace. On top of that, you really don't want a device that is supposed to last you perhaps a decade to be future proofed? Get real.
  • No, most people, most humans, and most current xbox owners right now probably dont have 4k tv.
  • There you go again throwing blanket statements out without giving any numbers to back it up. If you want to throw in worldwide population, then a large number doesn't even OWN a TV or even have electricity. I think we should make this discussion talk about 1st world countries since this will be a $500+ USD console we are talking about, wouldn't you agree? Since you refuse to give any numbers, here are some just from a quick search.
  • I'm not sure how those numbers show that most Xbox owners have 4k tvs
  • They don't, but it shows growth which 8s what I actually originally said about 4K. Either way, you are welcome for me proving your own point. 😜
  • ok, thanks for proving my point that most right now probably dont have 4k tv
  • your initial statement was most people don't have 4K TV's, now it's most people with an Xbox don't have 4K TV's. Should you really be changing your tune mid discussion? I mean, if we are talking global figures, most people don't have XBox One's. That being said, even if it's a ratio of 49% 4K 51% 1080P, yes, you are technically correct with your blanket statement that "most" people don't have 4K TV's but it's about growth, it 20% of people bought 4K TV's in the last year over 10% last year (arbitrary numbers, obviously) then the market is leading towards a saturation of 4K sets, which is where the money is so that's where businesses will trend. You need to look at the bigger picture otherwise, you're just, as stated, making blanket statements that add nothing to the discussion.
  • My nutty friend who has too much money then he knows what to do with and just loves the newest tech bought a Samsung Q9 85" (~$14K). So there is at least one person. 8K can be had for the same price as many high-end 4K TVs ($3,000 or so). And 4K itself will be in around 50% of households before end of 2021. And more then likely that percentage will be a lot higher with those that play on consoles. Plus, if Lockhart becomes a reality then you will have the option for a device that supports a resolution 1080p/1440p for a lot less money. And they aren't targeting 8K. They say it is capable of doing 8K which is true. It can technically output 8K video. That does not mean it is focusing on it. Pushing 8K requires 4 times the processing over 4K. And 4k requires 4 times the processing power to push pixels to the resolution that 1080p required. Minecraft in 8K is possible but Gears of War not likely.
  • The crazy part about the rumored specs is that Developers have been saying the PS5 is more powerful than this, but Xbox SX has better Ray Tracing capabilities. These next gen consoles are going to be powerful and I can't wait to see what games are gonna look like come mid gen.
  • Great, everyone will be pixel count shaming again...
  • There goes that "developers" talk again. You have references to something around E3 with a mag editor asked a few developers what was up. That is what we have as develpers. Somehow few became the standard. Also, lets not forget they could not have access to the Scarlett devkits at that time because no third party had one until November 2019 . Definitely not back at E3. And I highly doubt anyone at Mojang (the only game developer at Microsoft that also makes for PS) had at PS5 devkit. So, what you had was developers comparing a spec sheet (for Scarlett Anaconda) to a PS5 devkit that obviously had a Vega chip (Navi had not been released yet, months after E3). And a 12TF Vega (which is the TFLOPS these devs were quoting around) is around a 9.2TFLOP Navi. And Microsoft's spec sheet was actually increased from 10.xTF to around 12TF well after. And those are Navi numbers. If true that PS5 devkit back in E3 would have to been running at over 15TF to comparable to and adjusted to Navi's more efficient architecture. Which I doubt. Have the PS5 devkit numbers been adjusted to Navi? Maybe. But, comparing a specsheet vs devkit a while back is not quite exact science. When you were comparing apples to oranges with respect to different architecture numbers.
  • PCIE 3 NVMe at only 2 Gb/s? (That is still 4 times the speed of a SSD SATA 6 drive however.) That can be achieved with only a PCIE 3 NVMex2 drive (2 lanes of PCIE 3) Advantage: Cheap, Runs Cool. Most decent PCIE 3 NVMex4 drives (4 lanes of PCIE 3) hit 3.8 Gb/s as do PCIE 4 NVMex2 (2 Lane.)
    The top-end PCIE 4 NVMex4 drives hit 5.2 Gb/s. The reason NOT to go with PCIE 4 NVMex4 are twofold; Cost (quite expensive) and HEAT (they run very HOT and all need heatsinks at this time.) I have not heard of any Ray-Tracing ability in the NAVI series GPUs, so maybe that is the "Custom" part of it.
    MS could create a fully DX-12 compliant Ray-Tracing chip (as DX-12 fully supports it) without any IP issues, but I don't see it actually competing with the Nvidia RTX series as it won't have DLSS or the AI or other proprietary functions. My big wonder is: Will it support WiFi 6 2x2?
    I would hope so to future-proof it, but if they try to use that crappy Marvel chipset it will stink at it. Built-in Power Supply? I hope so, there is certainly enough room in it, but it might not have the heat-buget to support it with all the other power-hungry components. We shall see. Ports? Better be AT LEAST what the current XBox1X has.
  • So what you're saying is they just copied the PS5. Good idea, since M$ designing their own consoles has never really worked out. The 360 melted itself, and the slow RAM in the XBone handicapped it's performance.
  • Talking out of your annus I see.
  • I'm building an RX 5700XT gaming PC as we speak. I have a feeling the Series X I buy later in the year will actually outperom the beast I'm building. Gonna be a good year for gaming.
  • Wish my One X could benefit from an SSD internal drive. I may get an external one if I can find a deal on a 1TB. I installed a SATA 3 SSD in my PS4 Pro, and it is insane how much faster it is. My biggest memory hog is Destiny 2, and it loads in less than half the time. Game startup is faster, destination traveling is way quicker, and not so frustrating anymore. When my only friend that plays it on PS4 (others on Xbox) is on my fireteam, I'm loaded in and killed whole groups before he even shows up on the map. Sometimes loaded in, killed a bunch, and been killed and respawned, lol.
