Is there a decent 15W CPU for desktop?

post #1 of 5
Thread Starter 
Thinking about a random build that can run 24/7 that's close to an Intel Core i5 4300U laptop.

It seems that the Core i5 4300 U is only rated at 15W. 2C/4T.

So far I am seeing this Celeron but only 2 threads and is rated at 30W.

Where can I get something like an i3 or whatever that's only 15 or 20W for desktop?

Maybe inbuilt All-In-Ones or Atom based setups could be what you're after but I'm afraid you will never be able to buy a separate motherboard and CPU, that could use only 15-20W Max.

Not available from Intel Corp.

Thanks. Bummer.

I wonder why Intel won't make the laptop CPUs available.

What kind of a low power desktop can you imagine say about $ 200? I already have a PSU.

You can set power limit to 15W and undervolt the desktop CPU

Example
https://forums.anandtech.com/threads/haswell-to-broadwell-ipc.2433555/page-3#post-37472383

The desktop CPU in this case undervolts lower than the equivalent ULV laptop processors, costs less, offers higher performance and is socketed unlike it's soldered counter part. The mobile CPU typically can offer higher C-States though.

If your looking at a low power setup though perhaps an industrial mini-itx board with appropriate CPU. They support a variety of CPU's, both mobile and desktop and may operate off of a single 12V or higher supply. However usually more expensive.

Wait what? This sounds like it almost changes everything.

I might read more on it later but would I need a fancy CPU and/or motherboard to do this "undervolting" and "setting power limit"?
