The hardware is neither fast nor cheap, but with up to 128 GB of memory, there aren't many AI+ML workloads AMD's AI Halo can't run. The question is: is it worth $4K: www.theregister.com/ai-and-ml/20...
AMD’s Ryzen AI Halo makes local AI look easy, but at $4K, easy doesn't come cheap

ICYMI: AMD's 9950X3D2 isn't for gamers. It's also not for content creators. So who is it for? We get to the bottom of this weird little beast of a chip in our review over on @TheRegister www.theregister.com/2026/04/21/a... #AMD #CPU #PC #Workstation

An $899 CPU in this economy? AMD's Ryzen 9 9950X3D2 with its 208 MB of system cache hits store shelves tomorrow. But is it worth the $200 premium over the 9950X3D? I cover all of that in my latest review for @theregister.com www.theregister.com/2026/04/21/a... #PC #CPU #AMD #Tech

#ICYMI I tested Nvidia's GB10-based DGX Spark against the AMD Ryzen AI Max+ Pro 395-based HP Z2 Mini G1a. For AI development, the GB10 is hard to beat, but for an multi-purpose PC, AMD's Strix Halo is more flexible. Full story: @theregister.com www.theregister.com/2025/12/25/a... #AI #PC
Tested: AMD's Strix Halo vs Nvidia's DGX Spark
Hands On: Two tiny boxes, 128 GB apiece – but very different strengths

#AMD's Strix Halo (Ryzen AI Max+ 395) and #Nvidia's DGX Spark (#GB10) are an interesting class of hardware for local AI #development. Which is right for you depends on whether you want a #PC that runs AI or a PC for #AI. My latest for @theregister.com www.theregister.com/2025/12/25/a...

The Tenstorrent's Blackhole QuietBox is an impressive bit of #AI kit. - 128GB of GDDR6 - 2TB/s of MEM BW - 3 petaFLOPS of FP8 - 12.8 Tbps of interconnect BW - and an ambitious software strategy that... needs some polish Find my full review on @theregister.com www.theregister.com/2025/11/27/t...

Europe has joined the US as an exascale super power. EuroHPC's biggest iron has crested 1 EF on the Top500's HPL benchmark. Is HPL still the bench to watch when Blackwell offers more than 200x the FP8 perf as FP64? #sc25 My latest for @theregister.com www.theregister.com/2025/11/17/e...

Nvidia's biggest scale up domain is 72 GPUs. Google's is 9,216 TPUs. Historically TPUs have trailed on FLOPS, memory, & bandwidth. That's no longer the case with Ironwood. Google has a Blackwell-class TPU with absurd scale. More on @theregister.com ⬇️ www.theregister.com/2025/11/06/g...

I might be crucified for saying this, but OEM GPU servers are boring now. Everything is just a rebadged HGX box or NVL rack now. The only point of differentiation becomes whose lights out management interface does it have.
Say what you will about the hardware or the software, @tenstorrent.bsky.social's Blackhole QuietBox is a gorgeous bit of kit. Full review is already in the works #AI #Workstation #watercooling #Tech
This was a fun review. I don't think folks realize how big a deal the DGX Spark is. A year ago an #Nvidia #workstation with 128GB+ of VRAM cost tens of thousands of dollars. Is it better than AMD's Strix Halo? Now that's the real question. #DGXSpark #AI www.theregister.com/2025/10/14/d...

I love my dog. He's usually a very good boy. But having adopted him as a 10 week-old puppy less than a year before COVID hit, his anxiety can be overwhelming at times. He had a vet visit today. He got his shots, but wouldn't let the Dr. do a proper exam. We get to come back in 4 weeks and try again
