I think K1 is based on Kepler cores, or mobile Kepler cores.

Oh, even less believable then.

Charlie is grasping at straws as usual.

He said the exact same thing about tegra 4. He claimed the pre-release numbers Anand was showing were done by using well over 10W however tegra note 7 and shield perform better / the same and use considerably less power.

The fact of the matter is that you can't conclude anything based on a development board and a random power brick. Dev boards will always be over built. They need to be built well so there aren't going to be any issues with press demos, testing different chip configurations, testing higher clocks, etc. Being able to handle all sorts of testing and demos in various environments is what these sorts of engineering samples are for.

Does anyone really think that Nvidia (or any company for that matter) is going to design the board, the power brick and the heatsink from scratch specifically for this one part? And do so in a way that the HS, board and power brick can't handle more than exactly the estimated power draw?

Some common sense needed here.

Which is an absolute crock. HE lays it on thick and insinuates heavily. This website is pure rubbish, and it's consistent at that.

Charlie does sometimes have valid points. The problem with him is that frequently his points are over exaggerated and you have to navigate through bull to get actual valid information. Also check his sources, he frequently fuds his citations.

The heatsink with an active fan is concerning..... BUT it could be an engineering sample unlocked for overclocking or stress testing. It could also be from an early tape-out where the process is not mature yet.

I remember the last time someone freaked out about the heatsink someone showed a chip that I think ended up in a Samsung phone of some kind that had this monstrous, horrible-looking heatsink.

Let's all remember that intermediate engineering samples are not representative of the final product.

That's what I was thinking.

In all reality though, Maxwell will probably make a better tablet/smartphone GPU due to the crazy lower power draw that it has and the considerably higher performance.

Just remember kiddies, Maxwell has 8x the L2 Cache that Kepler has. biggrin.gif
