This looks like a good case for the ryzen 3000 series. They clock down to 0.2 volts(stall) at idle. And 7nm doesn't hurt.

The BIOS can throttle the CPU to stay within a predefined power envelope. Unless you know what the CPU clocks are doing, you cannot say that it's running as fast as this CPU was benchmarked to run, in other systems.
I don't know as much about the GPU, but Nvidia certainly allows for similar configurability, as they use the same base GPUs in laptops.
Don't you think it's at all suspicious that Michael didn't post any benchmark results?

Originally posted by schmidtbag View PostFair enough, though, it didn't peak that high for very long either. I don't think most people who get a PC like this are going to push the CPU under 100% load for extended periods of time.
Most buyers probably have in mind some rendering, simulation, or compilation workloads.

Wow, what a big loss.
If you agree with that statement and didn't interpret it as sarcastic, then don't buy something passively cooled (let alone one this small). I'm sure most reasonable people would realize some sacrifices have to be made, which in the case for this PC, means getting its full potential while putting under 100% load for hours at a time.

Originally posted by schmidtbag View Post*rolls eyes* You can say that for just about anything niche. Seems in this case, PTS identified the CPU as being 5GHz (obviously boost clocks) so worst-case scenario, you loose a few hundred MHz here and there.

No, because I'm not a pessimist and Michael is usually pretty good about telling us when things aren't settling right. Although it would be nice and appreciated to see benchmarks (particularly something like framerate over a given time, to see when/if turbo speeds start to drop), you don't buy a PC like this for the sake of raw performance under full load.
Without the benchmarks, we can't make an informed tradeoff of how much performance is being sacrificed (and extra $ charged) for sake of silence.
Originally posted by schmidtbag View PostYou could ask Apple the same thing about their high-end Mac Pros, and yet people are still buying those.
Originally posted by schmidtbag View PostA device like this could handling such workloads just fine, so long as they're not going for hours at a time.
Originally posted by schmidtbag View Postif getting the maximum performance potential is important to you, perhaps you shouldn't be getting a small passively cooled PC.
Michael is definitely burying something. I think he favors certain vendors - especially smaller companies that give him stuff.

Speaking as a vendor, for getting a skewed review one should look elsewhere. Phoronix benchmarks and publishes the findings. It's a site where quantitive results are more important than the cover story.

I'm not saying your products are bad, in any way - I just want to see the complete data. I'm not averse to sacrificing some performance for silence - I'd just want to know how much.
