Big question is on price. Anywhere from 400ドル to up (without the controller)

2nd issue is the 8gb vram
Although microsoft series S also has only 8gb of usable GPU memory (but it has fast direct storage with CF Express card as mitigation)

3rd issue is FSR 4 upscaling on navi 33 (tsmc 6nm) might have performance issues upscaling to 4k 60fps — compared to navi 32 or navi 31 (tsmc 5nm). AMD made some cutbacks in architecture for navi 33 compared to navi 31 & 32

As a mitigation, valve could certify game settings for 8gb vram (assuming FSR 4 upscales from 1080p to 4K).
  • For ex. We know some games can't play 1080p max/ultra with 8gb vram
    • PS5 ports
    • Open world games that use nanite like tech
Last as per steam stats bulk (50%?) of steam gaming is on igp/laptop gpus which are worse potatoes than the 7600m in GabeCube 1 — or similar with 8gb vram. All those people are targets for this device.

I like what I see so far. The Steam Machine would be an awesome console replacement or emulation machine.

Steam Survey Screen Resolutions

Full HD (1920 x 1080) continues to be the go-to resolution for most Steam users, holding a share of 54.44%. However, it’s no longer the fastest-growing option.

Higher resolutions are gaining traction, with 2560 x 1600 climbing past 5% and 1440p securing second place at 20.19%. While Full HD is still expanding, its growth rate has slowed to under 0.10%.

Steam survey by GPU VRAM

let’s examine how each of these capacities have performed since January 2025, when Nvidia launched its current generation offerings.

January ’25August ’25Diff.
8GB34.91%35.03%+0.12%
12GB18.52%19.30%+0.78%
16GB4.26%6.80%+2.54%
It’s important to note that current-generation 8GB models haven’t been on the market as long as their 12GB and 16GB counterparts. Nevertheless, mainstream x60 SKUs continue to prove most popular, with RTX 5060 enjoying the second-largest individual increase in share, behind RTX 4060.

Steam users GPU performance analysis by reddit user
Left 30% (yellow & red) would see benefits by upgrading to the Steam Machine 1

percentage-of-steam-users-by-gpu-performance-v0-d9te7ax9etxf1.png


Steam's hardware survey and videocard benchmark to make a histogram of Steam users graphics cards by their performance.

  • This data represents 82.24% of Steam users that opted-in to participate in the survey. The remaining 17.76% users either have a videocard other than these, or the cards were not specifically registered in the survey.
  • Each histogram bin represents a 2000 G3D mark, starting from 0-2000 for the first bin, up to 38000-40000 for the last bin, making a total of 20 bars.
  • Most popular high-end card is RTX 4070 at 2.16%.
  • Most popular mid-range card are RTX 3060 at 4.41% and RTX 4060 Laptop at 4.84%
  • Most popular low-end card are GTX 1650 at 3.02% and RTX 3050 at 3.07%
  • Most popular potato card is GTX 1050 at 0.71%.
EDIT: 5070 and RX 580 are repeated twice. They both should only be in the higher bin. RTX 3090 Ti & 9070 XT were not recognised in Steam surveys and were most likely put in the 17.76% generic/other cards.

EDIT2: The grouping is arbitrary. There is no agreed definiton on low/mid/high. Don't beat yourself up over it.

It's guaranteed to make the PCMR unhappy. They have dined on a steady diet of 8GB VRAM = garbage. So they are going to moan that unless it has subsidized giveaway pricing, it's a ripoff. HWUB predictably dumped on it as expected (the biggest purveyor of 8GB = garbage). Steve, can't see how it ends up being a success. Tim even claimed it would have to sell for 300ドル... :rolleyes:

Valve has been giving some broad pricing hints. The consistent hint: Pricing will NOT console equivalent, but entry level Gaming PC equivalent. Which I don't think anyone could interpret as lower than console pricing. They clearly mean higher. PS5 is currently 550,ドル and XBSX is 650ドル.

Further they added some additional clarity: We intend for it to be positioned closer to the entry level of the PC space, but to be very competitive with a PC you could build yourself from parts," Valve designer Pierre-Loup Griffais told The Verge.

That closest matched self build comes in around 700,ドル and that with cheapest components, and full size/mATX, since SFF would increase it to even more.. PCMR will call anywhere near that price DOA.

OTOH, it's looks like the best engineered SFF I've seen. It's a couple of classes above a minisForum PC. If someone isn't obsessed by VRAM, this looks like a fantastic miniPC.

Yea I don't care about the hardware. I hope it allows them to flesh out SteamOS for desktop PCs. That's where the real test is.

Microsoft can Game Mode all they want, but those wanting to move away from Windows isn't going to have that as a priority consideration. The day SteamOS becomes a viable OS on desktops, Windows will lose marketshare. It's not the lack of features. The reason it has bad battery life in Windows is a symptom of the MS mindset, not the culprit. The culprit is they are following the trend of stream-everything, own-nothing mentality while selling your private data as much as possible. Game Mode in that case is merely a Trojan Horse just to stay on Windows.

Some comparisons to top mini PCs:

www.ign.com

The Best Mini Gaming PCs Worth Buying in 2025 - IGN

Typically, gaming PCs are huge monoliths of glass and metal. However, there are mini PCs for gaming out there, if you need to reclaim your desk space.
www.ign.com www.ign.com

The Top recommended is: ROG NUC Mini Gaming PC Mini Desktop Compact Gaming Power with Discrete Graphics Intel Core Ultra 9 185H/RTX 4070/32GB DDR5 /1TB SSD

When I check Amazon, that is 2500ドル USD. While it is better performing, that is a mobile RTX 4070 - so it still has 8GB of VRAM (the main complaint against Steam Machine).

I'll grab the Budget option of another list:

www.hardware-corner.net

Best Mini PC With Graphics Card (AMD and NVIDIA) | Hardware Corner

www.hardware-corner.net www.hardware-corner.net

Minisforum Neptune HX100Gh with RX 6600M 8GB - 800ドル

Really, at 700ドル it looks like the Steam Machine would pretty much be the best Mini PC you could buy.

I think you have great difficulty finding any Mini PC with more than 8GB of VRAM for less than 1000ドル.

I don't think it really has to sell below 700ドル for the Mini PC market where it really doesn't seem to be anything close to it at that price.

Valve's Next-Gen Steam Machine and Steam Controller — the Big Interview​

"It felt like it was the right time."​



Valve on making the Steam OS more widely available:

are there plans to make SteamOS more widely available beyond a try at your own risk kind of model the way it is now?
definitely, just like Steam Deck paved the way for SteamOS on a variety of third-party handhelds, we expect that a Steam Machine will pave the way for SteamOS on a bunch of different machines in either similar form factors, different perf envelopes, different segments of the market and get to a good outcome there. ​
We definitely want to encourage people to try it out on their own hardware, and we'll be working on expanding hardware availability over time as well, or hardware support for the drivers and the base operating system. ​
​
Just last week we fixed something that was preventing us from booting on the very latest AMD CPU platforms. Last month we added support for the Intel Lunar Lake platforms. ​
​
We're constantly just adding support and improving performance and we want it to be at the point where at some point you can install it on any PC, but there's still a ton of work to do there.​

On enabling friction-free gaming

Can you talk about how the Steam Machine is positing itself as the more approachable PC gaming machine...
Something that happened shortly after Steam Deck released was that a lot of games started detecting that they were running on Steam Deck to pick exactly the right default settings for an experience that the game developer considered balanced, which is a pretty small amount of work for a game developer. ​
We expect the same thing will happen with Steam Machine, and we'll be providing APIs in Steamworks so that game developers can detect what platform they're running on to be able to have the right amount of detailed settings and that corresponds to the balanced experience that they have in mind.​

On the million dollar question (8gb vram)
Why did you pick the GPU you picked and why did you pick the CPU you picked when there are cheaper options or more powerful options?
piece of information that we always had available is the Steam hardware survey. So we can essentially look at everybody's devices, we understand what the medium performance looks like for people, we understand where the Steam Machine is going to be positioned relative to those. ​
We think that the Steam Machine is going to be equal or better perf than the majority of people on Steam. ​
So essentially we think it's going to be a good upgrade path for a lot of people, especially people who are on older machines​

On why a Steam Box?
the Steam Machine is just one option in the ecosystem of gaming PCs out there. ​
If you're already happy with your PC gaming experience, that's great. We love that. ​
We are a PC gaming company. We're just trying to give you more options. And that's how we view it. ​
It's just something that we think is a really great addition to a living room or a desktop, but it's just one other option that people can have available to them to play their Steam games basically.​

I think I watched this exact interview on YT. Yes they are clear, they want imitators and for SteamOS to spread to the desktop and they are working in that direction.

Anyone interested in a machine like this, but finding the the Valve Version inadequate can build their own with a more powerful CPU, RX 9060 XT 16GB VRAM, 32GB DDR5, but that will likely drift over 1000ドル if you use decent components...

From what I read, you can install SteamOS on this kind of All AMD system today. You don't have to wait for Valve to roll your own Steam Machine.
