Complete Hardware Specs Sheet of Xbox Series X Revealed

Microsoft just put out of the complete hardware specs-sheet of its next-generation Xbox Series X entertainment system. The list of hardware can go toe to toe with any modern gaming desktop, and even at its production scale, we're not sure if Microsoft can break-even at around $500, possibly counting on game and DLC sales to recover some of the costs and turn a profit. To begin with the semi-custom SoC at the heart of the beast, Microsoft partnered with AMD to deploy its current-generation "Zen 2" x86-64 CPU cores. Microsoft confirmed that the SoC will be built on the 7 nm "enhanced" process (very likely TSMC N7P). Its die-size is 360.45 mm².

The chip packs 8 "Zen 2" cores, with SMT enabling 16 logical processors, a humongous step up from the 8-core "Jaguar enhanced" CPU driving the Xbox One X. CPU clock speeds are somewhat vague. It points to 3.80 GHz nominal and 3.66 GHz with SMT enabled. Perhaps the console can toggle SMT somehow (possibly depending on whether a game requests it). There's no word on the CPU's cache sizes.
The graphics processor is another key component of the SoC given its lofty design goal of being able to game at 4K UHD with real-time ray-tracing. This GPU is based on AMD's upcoming RDNA2 graphics architecture, which is a step up from "Navi" (RDNA), in featuring real-time ray-tracing hardware optimized for DXR 1.1 and support for variable-rate shading (VRS). The GPU features 52 compute units (3,328 stream processors provided each CU has 64 stream processors in RDNA2). The GPU ticks at an engine clock speed of up to 1825 MHz, and has a peak compute throughput of 12 TFLOPs (not counting CPU). The display engine supports resolutions of up to 8K, even though the console's own performance targets at 4K at 60 frames per second, and up to 120 FPS. Variable refresh-rate is supported.

The memory subsystem is similar to what we reported earlier today - a 320-bit GDDR6 memory interface holding 16 GB of memory (mixed chip densities). It's becoming clear that Microsoft isn't implementing a hUMA common memory pool approach. 10 GB of the 16 GB runs at 560 GB/s bandwidth, while 6 GB of it runs at 336 GB/s. Storage is another area that's receiving big hardware uplifts: the Xbox Series X features a 1 TB NVMe SSD with 2400 MB/s peak sequential transfer rate, and an option for an additional 1 TB NVMe storage through an expansion module. External storage devices are supported, too, over 10 Gbps USB 3.2 gen 2. The console is confirmed to feature a Blu-ray drive that supports 4K UHD Blu-ray playback. All these hardware specs combine toward what Microsoft calls the "Xbox Velocity Architecture." Microsoft is also working toward improving the input latency of its game controllers.

Ohhhhh, I think I see it: the 192-bit chips share bandwidth with the CPU where the 128-bit chips are dedicated.

GPU is effectively 10 GiB at 128-bit and CPU is effectively 6 GiB at 64-bit.

Meh, if I ever to game on consoles it would be playstation. Xbox just does not have enough exclusive good titles.

Have to say this thing looks really good. I'll be buying both new consoles regardless, but hot damn, this is (so far) the one that truly tickles my fancy. Love the design too.

PlayStation 4 had a similar set up where CPU got significantly less bandwidth from the GDDR chips than the GPU did.

5700 XT = 9.754 TFLOPS

This chip is 12 TFLOP...


This thing is more than double the Xbox One X.


Also, 8K support was baked into Navi. It's likely there for 8K web streams or maybe BluRays with a firmware update. Maybe ATSC 3.0 could handle it someday too. Point is, the GPU is ready and able to decode it.



Hype rising for RDNA2. If they can manage this kind of performance with semi-custom then imagine what it can do on an AIB. I'm glad I waited to upgrade.
1825 Mhz with 52 CU yields about 12.147 TFLOPS FP32. According to DF, RT has ~13 TFLOPS equlavent.

XSX GPU has about 25 TF.

So apparently the slower bus is the one that's tied to the CPU and the GPU is aware of it so it can start pulling from that pool too if necessary.

560GBs 10GB gpu optimal memory, only problem is the cpu will eat alot of that 10GB-5,5=4,5GB, 560-336=224, so the GPU is left with 4,5GB at 224GBs.
The way I understood it, the fastest memory is reserved only for the GPU in the 10GB amount. The remaining (slower) 6GB is split between OS and CPU (and maybe GPU if needs more). Even if the CPU eats into GPU's mem pool, it wont be by the amount you mentioned.
I mean, upcoming titles in 4K with RT will definitely not run with 4.5GB of vram

I guess it depends what kind of games you play.
https://en.wikipedia.org/wiki/Category:PlayStation_4-only_games
There are maybe 3 games on this list that I'd want to play at all: Spider Man, Gran Turismo and God of War (maybe).
As for Xbox exclusives: I'd only miss Forza Horizon (which is my most played console game so far).

Vast majority of popular games are available on both platforms. I doubt exclusives are a serious factor for many.

For me Xbox wins because of the ecosystem.
Gaming-wise: Game Pass and Live are both good, Play Anywhere is nice as well and controller support in Windows is excellent. Frankly, I also prefer the controller itself.
But there's much more to it. I love that there's an app for OneDrive (and Dropbox as well). I occasionally use Skype too.
There's also very good integration with Assistants (not just Cortana) and automation frameworks (I use IFTTT extensively).
And there's a chance they'll go further with this philosophy.
If they do - I may even buy this stupid next-gen flowerpot.

PlayStation is very focused on gaming, which may be attractive for some, but for me it just doesn't beat the flexibility of Xbox.

$500 xbox console with PS5 coming in at $450+, it will take two years before there is any significant market penetration

Most buyers don't look at it as a cheaper alternative to a gaming desktop, because they don't consider a gaming desktop at all. :)
There's no "value". There's no "how many fps you can get for your money" philosophy.
It's a console - a box that makes gaming possible. Almost like a household appliance. But it suddenly got more expensive.

I bet you wouldn't be happy if washing machines got 20% more expensive with next generation - even if I tried to convince you they're still way more efficient than hand washing.

Also, I can't believe MS would accept the risk of selling this for breakeven price. People willing to pay more for the top product, including the group that games in 4K on PCs, will accept $600+. It's still cheap compared to their flagship smartphones.
Bulk of clients will get the new budget model or hold on to / buy an Xbox One X - there's a big chance it will support future games.

That's a misunderstanding. It has the equivalent of 25TF if the RTRT was done purely in shaders. The RTRT hardware can't do regular shader workloads, and thus does not translate back into FP32 TFLOPS.

Agreed. Though the difference between $400 and $500 isn't massive, it's still there, and $500 has scared people off before - hello PS3 and Xbox One! - though those were both inferior in performance as well, making it a double whammy of inferiority that this very likely won't be.

Here, though, you're off the rails. There's no risk in selling at break-even, as game licensing easily makes up for any lost profits there. $10 per title sold, plus a portion of all in-game purchases, plus Xbox Live and Game pass - that all goes a long way quickly. They have near zero risk in selling this at break-even or even at a slight loss. PCs are quite different here, as it's an open system, so no game licences, no subscriptions, no cut of in-game purchases, etc. - so all profits must be made ahead of time.

A great gaming machine with a cut-down semi-big Navi gen2 that will allow 60FPS@4K and 120FPS@1440P. What's not to like for $600? Just its iGPU's can be valued more than that compared to the ones on sale today.

Those are meaningless numbers to console gamers, they only care if it will play the latest Madden, FIFA, CoD game on their 4k TV with shinier graphics then the previous generation

10Gb of fast RAM, 6Gb of slow RAM...

The Nvidia 970 designers are smiling.
Memory with different speed have been always used in computing since its dawn and everything is tailored for specific needs. Having different memories with different speeds is not the problem rather than hiding it for commercial purposes.

Smart marketing can change the perspective of what a console can become with the next-gen ones. And then, the $600 monster will seem VERY cheap for what it will offer.

Anyone else question how long the system can sit at those clocks without heat concerns. Even if its 7nm, thats still a fairly big chip to be cooled. Though they are putting a huge heatsink on the thing.

Like a second. Nominal clockspeed is probably much lower.

...unless n7+ is really that good...

The beauty of gaming on a console is: you don't have to give a f... In fact: you shouldn't!
If the first thing you think about is: "but what about overheating?", you've literraly wasted a big chunk of the premium you're paying to Microsoft/Sony/Nintendo.
What you should think about is: "will it look well in my living room?" and "is the controller comfortable?"

It's a black box. It was designed and (hopefully: well) tested. We should assume it can do its part.
And if it can't - there's very little you can do to help.
And there are only 2 makers to choose from. And if you already got a console but you don't like it, it's hard to move to the competition, because you can't take your games with you.

Well I'm an engineer so I do consider it. Even if you dont have it, i can't help my brain.

Still too expensive. The specs of cheaper model will be what actually matter for majority of buyers.
What price is the XBOX Series X going to sell for? I don't see a price associated with it at the moment. And you cannot compare a console based system with a actual computer, in terms of cost. As the Consoles cost to make is a lot cheaper.

Itll probably be close to $600 im thinking.

DF reported that MS were very explicit in saying (and reiterating and underscoring) that clocks are entirely fixed. No boost, no throttling. Period. Reported clocks are 24/7 clocks. The thinking is that this is a console, so it should have X performance no matter what, as performance shouldn't be down to user configurations or tweaks like in the PC space. A good call if you ask me.

Expect this to be a hot (pun intended) box, and noisy if it has some fans to chill it down a bit.

At N7 node, that performance needs wattage.

It has one fan. I take it the pictures didn't load for you?
