Following up yesterday’s leak / announcement of the Xbox Series S, including its $299 price tag, Microsoft is today giving us a detailed look at the specs behind the upcoming console. The result? It seems pretty similar to the Xbox Series X...except for the GPU.

Microsoft detailed the Series S’ specs in a blog post this morning and in a 9-minute-long YouTube video this afternoon. The key takeaway is that the Xbox Series S uses the same CPU architecture as the Series X (albeit at a slightly slower 3.6 GHz clock speed versus the Series X’s 3.8 GHz), but a drastically less powerful GPU. At 20 CUs compared to the Series X’s 52 CUs, the Series S’ graphics processor can only muster 4 teraflops of power, as opposed to the Series X’s 12.15.

Four teraflops is even less powerful than the current-gen Xbox One X, which has 6 teraflops of power. Still, that’s not too unusual considering that, despite running older games, the Xbox One X targets 4K resolution while the Series S aims for 1440p. The better last-gen comparison, then, would be the Xbox One S, which has just 1.4 teraflop of graphics power.

That’s probably why Xbox Head of Platform Engineering and Hardware Liz Hamren said in the company’s blog that the “Xbox Series S delivers 4x the processing power of an Xbox One console.” She also emphasized its 120 fps support, something that isn’t possible on any Xbox One model.

Aside from the graphics power, the Xbox Series S also uses the same custom PCIe 4.0 NVMe SSD as the Xbox Series X, but reduced from 1TB of storage to 512GB.  In the Xbox 's video, it shows the Series S loading The Outer Worlds in 12 seconds, while the Xbox One S takes 53 seconds. 

The SSD also enables the Series S’ quick resume feature, which it shares with the Series X. Quick Resume lets players suspend multiple games at once and resume playing them later without needing to restart them. In the video above you can see the Series S swapping between 4 games within 30 seconds.

The other major parity between the Xbox Series X and the Xbox Series S is memory. While the Series X has 16GB of GDDR6 RAM, the Series S only has 10GB of GDDR6 RAM.

The Series S is also digital-only, which could prove an issue for players who want to keep multiple games downloaded at once, as the only way to expand the console’s memory (at least for current gen games) will be a proprietary 1TB Xbox expansion card.

At $299, though, the Series S seems like a good option for playing all the same games as the Series X, assuming you don’t care about 4K. And its touted ability to support 120 fps is nothing to sneeze at, especially for staying competitive in multiplayer games. We're looking forward to testing Microsoft's claims for ourselves come November.

    Ouch... 4 teraflops ain't great, especially compared to the Series X. It seems like the Series X is a much better value - $200 for another 500GBs, 12 more Tflops, 32 more CUs IIRC, and a Blue-ray drive, a higher clocked CPU and GPU, and 6GB more RAM. Yep, Series X is a much better value. Though, OFC, people will probably buy the Series S more, because $300.

    OFC, we shouldn't go by Tflops alone - cards can easily punch above their weight when talking about Tflops, but when comparing these two, it applies.

    lol MS what are you doing ?!!??

    6 GB less VRAM , 512GB less SSD , no Blueray , 1/3 Tflops of the real console ?

    for $200 less ? well people will just keep their old Xbox one X and wont bother about this dwarf...

    and how on earth are you advertising 1440P gaming with only 10GB total system RAM with RT ?? if the game itself takes 8GB for the game data, the GPU is left with only 2GB of VRAM ...

    Guys , this console is a disaster for the new Xbox series X do you know why?

    Because the Total Memory of 10GB only will make third parties not use the full Potential of the Xbox series X 16GB total memory , you wont find games that takes full capabilities of the bigger console to the edge ..

    No modern game works fine without 8GB of System ram and 8GB of VRAM .. new games are requiring 16 GB of System RAM AND 8 GB of VRAM ...

    MS crippled the capability of the bigger console software wise ... yes you CAN lower details to use less VRAM but System RAM that is needed cont be lowered much. so for games to work on both consoles they will never take full potential of the bigger console memory wise.

    Nah, plenty of people with Xbox One Xs will buy this - next-gen games, new look, bragging rights, next-gen features. The weird thing is that this is so much worse compared to the Series X, which on paper, actually does sound good.

    you dont get it , the Total RAM is what concerns me more ... games need VRAM and System RAM .. and given most modern games need 8GB to run , you will be left with only 2GB for GPU , this is not even enough for 720P with max detail.

    and lets say they make the game work on 4GB system and 6GB VRAM , for FHD gaming , this will cripple the game when it works on Xbox series X , this console will cripple the software houses from using the full potential of the "X" because they will have to make the software work on both. this is a disaster for the bigger "X" no game will take full potential of its hardware and work on both consoles , 6 GB difference is ALOT.

    Again, it's a $300 console, that should be able to run all the latest games, albeit upscaled from probably around 1080p or so in most titles. As I said in the other thread, most people won't be pixel-hunting, and many likely won't care much that the Series X renders at a higher resolution. There are still plenty of people with 1080p TVs after all, and at typical viewing distances, the upscaled output will likely look reasonably fine even on a 4K television.

    As for the RAM, consoles can use it more efficiently since they don't need to shuffle data between VRAM and system memory, so it's probably not as much of a concern as you are assuming. Having guaranteed SSD storage also means data can be loaded quickly off the drive, so less needs to remain in RAM at any given time. Today's existing console and PC games need to assume that they will be loaded off a slow hard drive, so they must keep more data loaded into memory at any given time whether they are running off an SSD or not.

    Ultimately, this version of the console is there for those who don't feel they can afford, or are just not willing to spend $500 on a console just to play the handful of games they might be interested in. This costs substantially less than an Xbox One X, and certainly isn't targeted at those who paid extra for that premium version of the last console. Microsoft is undoubtedly selling both versions of their console at a loss, at least at initially, and it probably wouldn't be practical to expect more hardware for $300.

    Still the 10GB total system RAM is a huge concern. and there is nothing called shuffle data , when your game textures on the screen needs at least 6GB of VRAM for 1440p leaving the system with only 4G of ram to run with ... this is a serious issue.

    The ram capacity is lighter then I would like to see but it isn't the gulf your making it out to be either. First the OS is supposed to only need 2.5gb to run leaving 7.5GB for games data like textures. Second the SSD will be able to stream textures much faster than the HDDs of old helping fill that ram much faster minimizing the need for more ram on both consoles. Third with ML textures on both the Series X and S this will take a great deal of workload off the systems as well. I truly would have liked to see both consoles come with another 2GB of ram but just because they didn't I don't think it the problem you perceive it to be. But yeah check this out...

    There's a reason why top selling multi-platform games such as Madden 21, NBA 2k21, and COD Black Ops Multiplayer (revealed today) have shown their footage running on the PS5 and you just gave the reasons.

    This makes absolutely no sense PS five is not better than a series X and this was not a story about the series X. Please take your fanboy comments somewhere else

    You are wrong , The OS meory hasd nothing to do with the Game memory need . Any software needs memory to run and store gaming data and not texture data ... Most games need at least 8GB of RAM to run , if you take out from it 2.5G for the OS , you will still need 5.5GB for the game to RUN , then Above that you will need Memory for the GPU and for the Textures ...

    dont mix between OS Memory need and Software need which is Additional !!!

    Minimum RAM needed for most modern games is 8GB , PLUS 4 GB VRAM for FHD , 6GB VRAM for 1440P and 8 GB VRAM for 4K gaming.

    This will give you Total of 12GB (FHD) ,14 G (1440P) , 16 .GB (4K)Total Console RAM ..

    10GB TOTAL CONSOLE RAM is very low for modern games ...
