The part here I find funny is that AMD&#x27;s market cap currently sits at @ 2x Intel&#x27;s so the analysts of the world obviously think they&#x27;re sitting on something. And yet they are <i>still</i> in headlines as the market underdog.<p>For anyone who doesn&#x27;t follow AMD at all (good move, their consumer support for compute leaves scars) they appear to have a strategy of targeting the server market in hopes of scooping out the high-profit part of the GPGPU world. Hopefully that does well for them, but based on my years of regret at being an AMD customer watching the AI revolution zoom by, I&#x27;d be hesitant about that translating to good compute experiences on consumer hardware. I assume the situation is much improved from what I was used to, but I don&#x27;t trust them to see supporting small users as a priority.

This isn&#x27;t so directly related, and I know that performance figures are highly workload dependent and always under the headline figures but I want to take a moment to point out the <i>multi-petaflop</i> figures. Yes they&#x27;re not full precision, but still. How long ago would this have felt like an outrageous supercomputer?<p>Quick thing to show the sheer scale of these figures. This is 10^15 operations per second, and if you sit a foot from your screen that takes light about a nanosecond to reach you. That means that from the light leaving your screen to it hitting your eyeballs these things can have done another million calculations.<p>I know this isn&#x27;t particularly constructive, but I&#x27;m hit with waves of nostalgia and older performance figures seeing this.

The price is good compared to Nvidia H100 or B100 at around $15k.

Supposedly last in the line of CDNA? AMD said they are switching to a new Unified DNA&#x2F;UDNA in the future, merging both Radeon&#x2F;consumer and Compute&#x2F;data-center. <a href="https:&#x2F;&#x2F;www.tomshardware.com&#x2F;pc-components&#x2F;cpus&#x2F;amd-announces-unified-udna-gpu-architecture-bringing-rdna-and-cdna-together-to-take-on-nvidias-cuda-ecosystem" rel="nofollow">https:&#x2F;&#x2F;www.tomshardware.com&#x2F;pc-components&#x2F;cpus&#x2F;amd-announce...</a>
