very insightful.

i always "knew" all that, and even followed ken shirif(i probably recalled the name wrong) deep dive into older cpus... but i didn't actually know bining now was about entire cores! i assumed it was a couple extra paths and features. makes sense i guess but before those visuals i never thought much about it.


Binning by core has been done for a long time, actually. I remember it being a thing with Sempron and Phenom, where AMD was so aggressively binning that you could unlock the locked core(s) and go from dual-core to quad-core.



I really enjoyed the details, just curious why he has comments turned off on the video? Looks like all his videos have comments turned off... feels like there is a story there?


Beyond rude people making rude comments, I imagine the channel gets lots of bot spam, especially crypto scams, given the content’s proximity to the space.


Youtube comments devolve into garbage rapidly. Not worth the headache.


Probably the right choice. Go open the YT comments for just about any video and count how many high-quality discussions are being had. I'm usually surprised to see even one well-thought out question or comment.


Fair enough, I figured his high quality content would lead to good conversations, but I guess no one is immune to comment garbage!


Bot spam on youtube is insane: I have a number of tiny view count videos (electronic test equipment teardown/repair -- no production value in the video, it's mostly intended as a reference for the next person doing a similar repair) and I regularly have to remove comments from the pornographic avatar bots. It's enough to be annoying and I am considering turning off comments even though I don't even have many videos, many views on those videos, or proximity to a money fountain.

I image it helps keep discussion more civil and improves their quality by introducing a barrier.


good call, was going to drop a thanks at the very least!


It's fascinating to see how Zen architecture has evolved and how its advancements are impacting performance in both general computing and specialized tasks like those using CUDA and Tensor Cores!12345
