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…

I just don't get why most people care? It's 60% more expensive, too. Even the 7900XTX is ludicrous at $1000.

Give me a $400 card from this generation that competes with a $500 card from the previous generation, and I'll call it a win.

A $1600 card winning anything seems like an irrelevant battle. Is the volume / sales for those cards high enough to be the real focus, when cards like the GTX 1060 were the volume leaders by a long shot?

Oddly, to me this just sounds like efficiency gains by potentially introducing massive security holes i.e. the vector of the Meltdown/Spectres of the future. It also seems like they're trying to sell AI as some sort of secular qubit that they'll be error-correcting.

But don't forget that TSMC's margins for massive bulk purchasers like AMD will be lower than the average.

Does TSMC even have non-bulk customers at 7nm/5nm/4nm? I would have thought the mask costs are so high that it isn't economical except for the biggest companies.

7nm yes, 5nm/4nm not as much, apple pretty much bought out the entirety of 3nm. 7nm is a relatively mature process at this point.

AMD already uses a Perceptron for their branch prediction. I would say they're talking about support for ML speed ups in hardware but maybe the plans also include a more complex complete neural net in hardware for data prediction.

I see what you did there.

Please explain!

Bulldozer [0] was a major flop. Sounded too good to be true: 2 cores sharing the same FPU because integrated GPUs should be executing these instructions much faster anyway. Maybe it was just ahead of its time and they simply couldn't deliver

But it failed hard which coincided with Intel releasing a major winner with their last planar architecture - sandy bridge.

As a result, AMD spent years circling the drain and their stock dipped below 2 dollars. Some people made good money buying around that time.

Edit: oh, I missed the exclamation mark haha. Oh well. Too tired to even feel ashamed

Not a cpu designer, but I remember AMD using AI for branch prediction since long ago. Hopefully they still mention AI in that sense and not only branding.

AMD should build an arm chip. There's only so much efficiency you can build into the ageing x86_64 architecture

The only reason ARM is competitive with x86 is due to heavy borrowing of its tricks (i.e. OOO execution). At the end of the day, Apple M2 and AMD Ryzen cores are not all that dissimilar.

AMD CEO, Dr. Lisa Su, has identified energy efficiency as the next challenge for the company. With the growing demand for high-performance computing, it is crucial to ensure that energy consumption is minimized to reduce the environmental impact and operating costs. AMD has already made significant progress in this area with their latest processors that deliver excellent performance while consuming less power. Dr. Su's focus on energy efficiency underscores AMD's commitment to sustainability and innovation, and we can expect to see further developments in this area in the coming years.
