The old Nvidia Sli had 1GB/s bandwidth, and typical video memory bandwidth was over 100 back then. Now the latest version of NVLink has a bandwidth of 1800 GB/s, and the RTX 5090 has about the same memory bandwidth I think.

Interesting to see gfx1013 (PS5's Oberon SoC) binned down for mining use that they've called 'AMD-BC250.'

Inside Ironwood's architecture: 9,216 chips working as one supercomputer

Ironwood is more than incremental improvement over Google's sixth-generation TPUs. According to technical specifications shared by the company, it delivers more than four times better performance for both training and inference workloads compared to its predecessor — gains that Google attributes to a system-level co-design approach rather than simply increasing transistor counts.

The architecture's most striking feature is its scale. A single Ironwood "pod" — a tightly integrated unit of TPU chips functioning as one supercomputer — can connect up to 9,216 individual chips through Google's proprietary Inter-Chip Interconnect network operating at 9.6 terabits per second. To put that bandwidth in perspective, it's roughly equivalent to downloading the entire Library of Congress in under two seconds.

This massive interconnect fabric allows the 9,216 chips to share access to 1.77 petabytes of High Bandwidth Memory — memory fast enough to keep pace with the chips' processing speeds. That's approximately 40,000 high-definition Blu-ray movies' worth of working memory, instantly accessible by thousands of processors simultaneously. "For context, that means Ironwood Pods can deliver 118x more FP8 ExaFLOPS versus the next closest competitor," Google stated in technical documentation.

The system employs Optical Circuit Switching technology that acts as a "dynamic, reconfigurable fabric." When individual components fail or require maintenance — inevitable at this scale — the OCS technology automatically reroutes data traffic around the interruption within milliseconds, allowing workloads to continue running without user-visible disruption.

This reliability focus reflects lessons learned from deploying five previous TPU generations. Google reported that its fleet-wide uptime for liquid-cooled systems has maintained approximately 99.999% availability since 2020 — equivalent to less than six minutes of downtime per year.

(hope this doesn't count as "tech support"!)

I have seen some say that the difference between fake and legitimate PTM7950 is totally overblown and that most phase change pads will perform very similarly- genuine or not, but then have also obviously seen the far more common "genuine is WAAAY better than the fakes!" as well. I'm just wondering if anyone has actually tested the differences between them? I've tried looking it up and surprisingly am somehow unable to find a single post anywhere of someone that tried them both and reported any differences in their performance, but I don't know if Google is just being stingy with the good search results (orrr that I just suck at doing research lol)? Sooo yeah, has anyone seen this done anywhere?

Thank you!
