@HPC_Guru Definitely you, your posts are so important for me keeping up with HPC news.

#SC23 asks: Who Is Your “I AM HPC” Hero?

Check out my latest feature about the best GPUs Nvidia and AMD have ever made. This was an interesting one compared to my best Nvidia GPUs and best AMD GPUs features at Digital Trends because I had to select way fewer cards and tell a narrative about general industry trends rather than focusing on what was happening at each company in particular. I would have liked to split this up into two features for a total of a dozen best cards but oh well.

Got a new pair of headphones in with three different connection options: USB receiver, Bluetooth, and aux. Don't need multiple headphones anymore, thank god.

@jonmasters Man and I thought I pulled up lots of tabs for researching stuff... you're on a whole other level.

@jonmasters Jon why do you have so many Gmail tabs?

Notebookcheck has a Ryzen 9 7945X preview out and it's close to what I predicted last year (in this article: https://www.digitaltrends.com/computing/ryzen-7000-could-be-a-serious-threat-to-intels-mobile-chips/). I'm pleasantly surprised that Intel's best chips in the best laptops can stand up to AMD's, but the 7945HX consumes nearly half the power. A Ryzen laptop can have equal performance to Intel's best while being much smaller and perhaps even cheaper. Not good for the blue team. https://www.notebookcheck.net/AMD-strikes-back-Ryzen-9-7945HX-beats-Intel-Core-i9-13980HX-despite-much-lower-power-consumption.698349.0.html

Personally I wasn't expecting there to be any cases where the 7950X3D was slower than its non-3D counterpart, but there are a few. These seem to all be lightweight esports titles so presumably the amount of cache and memory they use is so minimal that losing the frequency is actually a net loss. Increasing the clock speeds on the other CCD didn't seem to really do much, but maybe AMD can somehow optimize the 7900X3D and 7950X3D on a per game basis?

Interesting side of V-Cache I hadn't considered before, it improves frame per watt metrics significantly (at least in Linux). Cache > frequency is definitely the new normal for gaming oriented products.

Seeing alot of people disappointed with the leaked Ryzen 7000X3D reviewer's guide and its performance claims. V-Cache is providing a smaller performance uplift for Ryzen 7000 but that's because Ryzen 7000 already did a ton for improved gaming performance: higher clock speeds and greater L2 cache. It's not surprising to me that X3D this generation is only marginally ahead.

The interesting part about this is that the 3nm components may not even be the ones that are actually delayed, but some other chip. If one tile is late, might as well delay all the others too. https://www.pcgamer.com/intels-reported-3nm-chip-deferment-hints-at-a-delay-to-arrow-lake-cpus/

@HPC_Guru Do you think they still want to be taken seriously in HPC? I’m not so sure. Seemed like a good idea three(?) CEOs and six(?) years ago, but their focus seems to be on just catching up with TSMC and stopping the bleed to AMD.

@EposVox Missing a few drive bays too... how old is this thing?

@HPC_Guru @glennklockwood Or taken seriously in general. Honestly Intel's strategy here really doesn't make any sense, they're trying to make a comeback with all this fancy technology without even knowing how exactly it's all going to pan out. Very different from AMD's execution strategy which developed steadily from 2017 onwards.

@HPC_Guru It's hilarious that we're wondering whether or not it might launch this year. At this point Intel needs to count on AMD and other rivals screwing up.

Tired waiting for the oft-delayed #Aurora #supercomputer at Argonne?

Intel has produced a video about Borealis, a test system for Aurora at Intel’s supercomputing lab in Oregon

Another PCGamer writer with a great piece about how insane GPU prices have become. Don't fall for the marketing, AMD and Nvidia are basically scalping you. https://www.pcgamer.com/where-the-heck-do-gpu-prices-go-from-here/

I'm actually kinda proud of the PC community mostly not freaking out about that 7950X3D benchmark and being like "we know, the performance is lower sometimes." It's not often that most users actually grasp these kinds of exceptions.

I'm not convinced by the rumors that Meteor Lake is only capable of replacing Raptor Lake in laptops. If Intel wants, it can be a full fledged successor on the desktop too. https://www.xda-developers.com/meteor-lake-less-cores-raptor-lake-slower/

There's just not a ton of analysis here, and his little PowerPoint slide says almost as much as RGT does himself. Usually in a presentation I'd expect the slide to summarize the main points, not to be almost the entire substance. The lack of in depth technical analysis (he focuses more on core counts than anything else) gives me the impression that RGT either doesn't have good sources or isn't good at this whole leaking thing. I've seen better technical analysis from leakers who were wrong.
