[SA] Nvidia’s Tegra K1 draws a shocking number of Watts

The demos that Nvidia clams show a better performance per watt than Apple’s A7 were skewed to the point of being intentionally deceitful, there is no way it can be replicated in products for reasons explained in the link above. OpenGL full is claimed as a feature, something Imagination for one has offered for years but no customer implements for power consumptions and suitability reasons. Worse yet the raw power claims made by the company were called in to question by the demo systems shown off.

How many power supplies are actually used to their max? Sure, the brick can feed 60W. Does that mean the rig is pulling 60W? No. Electricity doesn't work that way.

Did you bother to read the article? He doesn't say it draws 60W.

It's Charlie. He basically comes with hypertension (grain of salt).

I know Charlie is really big on hating Nvidia, but his conjecture is still worth considering. I honestly wouldn't be surprised if K1 pulled upwards of 15W on decently heavy loads. What we've seen of Maxwell thus far is impressive for sure, but 192 cores at nearly 1Ghz for anything under 10W? It just doesn't seem believable.

That's Charlie, there's usually a grain of interesting truth buried somewhere in there... That version of Tegra does seem like a big, heavy duty SOC.

Does SA still have that absurd paywall?

Yes, on certain articles. But the community forum sometimes discusses them thoroughly.
