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…

> The Nvidia 4090 turned out to be far ahead of the AMD 7900XTX. 7900XTX is on par or better than 4090 in alot of games, as well as some games favouring nvidia more than amd... (obviously not talking about Ray Tracing) Coupled with a lower price... I'm not quite sure what you're talking about since you're saying the oppisite is all reviews I've seen.

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…

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.

Re. The “hybrid algorithms” bit: I was at this talk. The example she gave was a physics sim like CFD, iterating between a fast/approximate ML-based algorithm and slow/accurate classical physics algorithm, with the output of each feeding in as the starting point of the next round. But this was just an example, clearly there are lots of area you could apply a similar approach.

I think its also leaning into their new product MI300, which has 24 cpu cores with 8 compute dies. Both CPU and GPU (and memory) on a single package. Conventional processing + AI together. Hybrid approaches.

Graviton, M1/M2, Ampere etc but I’m sure you’ll be able to explain why Arm is seen as ‘legacy’ tech when billions of smartphones are being shipped every year with Arm CPUs.

Oh look, you named 4 areas where ARM development has already peaked. Hyperscalers are already looking to evolve from ARM in the near future, just look at how much attention Ventana got at RISC-V Summit. M1/M2 are Apple ecosystem specific phenomenon that haven't inspired any copycat products. Ampere has been a massive disappointment to everyone in the industry, see the fact that Nuvia had their entire business dead-to…
