Valve reveals general hardware specs for its prototype Steam Machine

Last week, Valve announced its general plans to launch a new living room PC gaming hardware and software initiative, including the planned launch of Steam Machines. At the time, Valve said it will be picking 300 people to get a prototype Steam Machine that would be made by Valve for testing later this year.

Today, Valve announced the general hardware specs of those Steam Machine beta products on its Steam Universe community page. Valve indicates the prototype is meant to be a high-performance rig, but the Steam Machines that are due to launch in 2014 from third-party companies will have a range of hardware performance.

The 300 Steam Machine prototypes from Valve will have these basic parts inside:

  • GPU: some units with NVIDIA Titan, some GTX780, some GTX760, and some GTX660
  • CPU: some boxes with Intel : i7-4770, some i5-4570, and some i3
  • RAM: 16GB DDR3-1600 (CPU), 3GB DDR5 (GPU)
  • Storage: 1TB/8GB Hybrid SSHD
  • Power Supply: Internal 450w 80Plus Gold
  • Dimensions: approx. 12 x 12.4 x 2.9 in high

Valve has yet to offer any images of the Steam Machine prototype case, simply because they claim it's not yet finished, though the company says they'll reveal the design prior to shipping the prototypes.

So, its just a Linux PC, just like a normal PC that I can buy down at the PC shop ?

So the Titan is priced (itself) at $1000-$1300 (AUS)
I7-4770 $335-$360 (AUS)
1TB SSHD $114-$135 (Aus)
16GB DDR3-1600 $130-$177
450w 80Plus $50-$60
= $1676 - $2032 (AUS)
Edit: Case not added in price

This is for the expensive parts (Price taken from http://www.staticice.com.au/index.html )
I'm going to Stick with the PC and Xbox .... anyway, I'm over STEAM

Yes it is indeed just like a regular gaming pc BUT oem's can buy parts in bulk so they will be paying a lot less for the cpu, gpu etc. Also their cases are much smaller and thinner. They will likely have psu components soldered on the mobo. You would have to use a full size atx psu if you bought one from a shop or built your own.

Sounds counterintuitive, but don't listen to the manufacturer. it's the biggest load of BS going. 450w is again, perfectly adequate for a Titan.. i'm not kidding

plus, Valve wouldn't chuck a 450 in if a Titan would go over, right?? Surely that'd be a "simple" error, but the fact is, it isn't an error. A Titan system won't touch 450 unless it's SLI

Anand explains here as well

http://www.anandtech.com/show/...tans-performance-unveiled/2

a titan wont even break 265w. Since Valve are chucking in a Gold PSU, the 20% efficiency loss will more than cover this system

You do understand that other parts need power as well and if they max out the 450w the PSU will simply fry over time right?

of course.. a modern high end CPU will draw at most 85w.. at most.. and games wont draw that from a CPU anyway. HDD? 5-10w. Seriously guys, 450w is fine

exactly, nvidia recommend 600w because they don't know how many optical drives and hdd's you have attached. 450w is plenty of power.

They recommend 600W because there are PSUs out there that claim to be higher wattage than they actually are. They combine the +3.3V, +5V and +12V rails for a total. While it's mostly the +12V rail that counts. Most high quality PSUs have 99% of their power on the +12V rail, some oven have more (like the Corsair AX1200i which has 1205W at +12V). Some very low quality PSU have less than 50% of their total wattage on the +12V rail. So while claiming to be 700W, it's actually just 350W.

Just because the TDP is 85 doesn't mean it draws 85 under load. Go read and educate yourself about it first and then start arguing.

1. I'm not arguing. I replied civilly
2. Read what I said again, and you'll find what we said are one and the same thing
3. At the end of the day, I'm right. For the system as advertised by Valve, 450w gold is adequate.

I run my GTX 770 fine on my 500 watt power supply with a i5 2500k @ 4GHz.

It really depends on how many internal devices are drawing power, what their load is, etc. A 450 watt power supply with a single graphics card is you pretty much begging for an unstable system when at high load, unless that power supply is at least 95% efficient. A lot of power supplies never provide the maximum level of wattage they indicate due to inefficiencies and energy leakage, sometimes as high as 20% on some units.

A single GTX Titan at max stress load will consume around 372 Watts, and the minimum recommended power supply for the GTX 770 and GTX Titan is 600 watts.

A motherboard + Haswell chip at full load could consume another 40-80+ watts (partially depends on onboard features).

If you have a single GPU, Nvidia's recommendation of a 600 watt minimum power supply is accurate. If you have two GPU's, you probably shouldn't have less than 1000-1200 watts.

Then don't run stress tests... A system with an i7 3960X @4,3GHz and a GTX Titan will draw about 430W out of the wall. Counting in the inefficiency of the PSU, it counts as 380W or less (This is at a gaming load, max load you'll ever get, unless seeking to draw more power). If this is a good quality PSU with 36-37 A on the +12V rail, It'll do just fine with enough overhead. And using a 1000-1200W for dual GTX 770 is just nuts! They'll do just fine (overclocked) with a good quality 650W PSU!

You might now....but in a year or two you might not be if the capacitors deteriorate to a level where the power provided doesn't cover it. Running a PSU close to max more of the time speeds up the degradation. Good ones are 80% efficient to start with so they never really deliver the rated wattage. As time goes by they deliver even less. Once you start hitting that regularly with your uber components you start having crap outs and wonder what the hell is going on.

I have a GTX 760 and a quad core processor and I wouldn't put it on anything under 550W. Luckily mine is 600 so I have plenty of room.

Linux steam games. Wow, look at that selection.... Yay.
Another Linux Distro, now with more proprietary code..... More Yay
$1000 PC with above included, a weird controller that no one understands VS Next gen consoles with standards and devs who can code to the metal to get more out of it for half price....The winner is clear

you do know Steam OS and well for that matter Steam boxes is 100% completely open so you can do what you want with it

Although Windows 8 is not open source I can do what I want with my PC that anyone could do with Linux. So what does steam offer that is different?

well if you was one of the lucky who end up getting a steam machine you can do what you want with it including installing windows 8.1 if you would like as it is to do what you want with it

except play direct X games (so that's 75% of the market not in steam/Linux)

I just don't get why Gabes even wasting his time tbvh.

Actually the PS3/4, Wii U, iOS, and Android platforms don't use directx, nor most embedded systems in the world, so developers are quite used to it. All it takes is a viable platform where there is money to be made, and this is what Valve is bringing to the table.

Yea most modern game engines run openGL as well not just Directx thus those game can nativily run on linux well near native as ther is slight conversion code i am sure that is used or done but still . and currently the same games on linux steam seem to run better then windows with the same feature set in some test but anyways

The Steambox will come with more launch titles than the PS4 and XBox One combined. There are some AAA titles lacking, but Valve are "working on that".

Less license fees and more customizations are available to ensure decent performance. This is the same reason that the PS4 uses BSD as it's base for the Playstation OS.

The Piston is not an official steam box, and is running a 50% profit margin.

The Wiimote was far more different than the controller Valve have developed, and most people adapted in about 5 minutes. Most feedback about the controller has been positive so far.

Steam OS has been tweaked for best gaming performance, so it'll probably be pretty performant for plenty of games. You do make a valid point in this case though. The extremely limited hardware variations on XB1 and PS4 may very well make them faster, but then a Steam Machine can come with a Titan, so there's that.

NightScreams said,

It most certainly is not. It's probably not going to be any Steam machine, but it remains to be seen if the SteamOS machines will do well or poorly. It's got a lot of stuff going for it, but depending on things such as price and availability of AAA titles, it may also suffer as a result.

All in all, don't let your console fanboyism get in the way of a balanced opinion .

Then build one with matching parts and download the software.

Honestly I would think that they don't care about profiting off the hardware as long as they can profit on the game purchases during the lifetime of the hardware.

Exactly, or buy one from another OEM. I don't have a problem with it, outside of it being boring haha. Just what we need, another OEM using the same parts as everyone else.
