Energy efficiency and improved packaging are things I can readily agree with. The last thing though - “hybrid algorithms leveraging AI efficiency” sounds an awful lot like a buzzword sales pitch. This article reminds of this other one [1] posted about 1 month ago. It’s an interview with some guys that just got done building an exascale supercomputer, in which it was originally estimated to need 1000 megawatts but ult…

What are hybrid algorithms supposed to be anyways? Half algorithm & half dictionary? Half algorithm & half user manual? Half algorithm & half class?

The article gives a concrete example in the same paragraph: "For example, AI algorithms could get close to a solution quickly and efficiently, and then the gap between the AI answer and the true solution can be filled by high-precision computing."

Interestingly the example is backwards (statistical reasoning first, hard reasoning second) compared to traditional usage of "hybrid" in AI and control contexts.

From the article it looks like half AI guessing the solution, half some static algorithm fixing the result to be better. Not sure how it's supposed to really work.

one variant of this is sciml approaches where you use an ODE solver wrapped around a NN. the ODE solver guarantees you get the right conversation laws which NNs don't do well and the NN is more accurate than the hand written model since it doesn't ignore the higher order effects.

AMD is having some challenges at the moment. In particular, the RDNA3 graphics card line launch has been a dud. The Nvidia 4090 turned out to be far ahead of the AMD 7900XTX. Then there turned out to be an overheating issue on the AMD cards. And now it just looks like both Nvidia and AMD are price gouging GPU buyers instead of competing with each other. They are deliberately keeping prices high and creating artificia…

>They are deliberately keeping prices high and creating artificial shortages of GPUs

you've seen evidence for this, or it's your opinion?

>AMD had a chance to really pull ahead of Nvidia

with a graphics card line that you just told us is far behind Nvidia's?

Put another way: if AMD (and especially Intel) don't do something about this they're going to get completely eaten alive by ARM. The amount of processing power available in a modern smartphone is truly mind-boggling. I'd love to see a chart showing the chip cost and energy cost of the power on an M1 chip in each previou syear. I would guess that 30+ years ago you'd be in the millions of dollars and watts of power but…

Honestly I don't understand why there's not something like a 256 core ARM laptop with 4TB RAM. The benefit of ARM is scale of multitasking due to not requiring the same kind of lock states that Intel's architecture requires, and can additionally scale much better than only one physical+virtual core pair. I guess the only thing that's holding back ARM is Microsoft, as laptops are expected to run an desktop OS that peo…

I think because general compute is hard to parallelize, so 256 cores doesn't help much in practice. (Compute that does parallelize well already runs on GPU).

Half SQL statements and half array.sort() methods I assume.

What if all the text in your comment was approximately the correct set of letters in each word?

Their graphics division has certainly been lacking vs Nvidia's cards, but are still far ahead of Intel's. Their desktop and server CPUs are crushing the market.

> They are deliberately keeping prices high and creating artificial shortages of GPUs

That's simply not true. Check out TechTechPotato's youtube channel for the explanation on this, but under-shipping isn't price fixing. They're just shipping less to distributors because there's less demand, allowing the distributors and retailers to keep a stable amount on hand.

In my experience talking to semiconductors folks, ARM is just not a concern anymore. The future is RISC-V, and ARM is already being seen as legacy tech. ARM's progress in the server space has stalled, the ARM Windows ecosystem is dead, Android has laid the groundwork for a move to RISC-V, and ARM has never and will never touch the desktop market.

If RISC-V support by Microsoft is as bad as it has been for ARM, then I'm afraid RISC-V will never touch the desktop market, at all. Contrary to ARM, which is being pushed there with great success by Apple. Server-wise of course it's a different story...
