    Some AMD engineering samples with strange performance figures have been popping up in the UserBenchmark database recently. In an effort to put those results in perspective, AdoredTV just uploaded a video that starts with a brief history of CPU memory hierarchies. Then, he attempts to analyze just what's going on with the AMD engineering sample's inconsistent latency curves.

    Check it out in the video here.

    A look back to the early days of cache-less computing, to what's coming next with Zen 2.

    Good info in that video, still wondering about that most recent Userbenchmark find though....

    Someone should show this video to Jensen and teach him how to present computing history information in a compelling way.

    Jensen presents computing history as he remembers it... *sigh*

    Nice way to present the concept of caching, the first half would be great material for some aspiring tech college freshmen.

    wow i saw the length, was like meh i'll just skip through this... 42 minutes later and didn't skip a single second of it.. i'd say that's about as idiot proof as it gets to explaining how cache works, thanks.. nice job Adored.

    Of these alleged benchmarks, how much more computational power are we getting per core from the 2000 series?
    Assuming we can calculate that.

    It was very enlightening I enjoy these kinds of videos that educate and dispel a few myths, often people tend to just assume or fill in gaps with what they believe and it can cause wrong info to be repeated or bogus info to run circles where groups of people will regurgitate it on forums.

    I can't help but wonder, is this bloviating Scotsman paying the [H] for links? He sure does pop up on here rather often :p

    He might be a little long winded, but I'd take content like this over a graphics card unboxing any day (no offense [H] ).

    I thought it was real informative. And I guess the RAM latency, more than the sheer throughput is more important to CPU performance when you pick high speed RAM. Makes sense.

    His content can be interesting, but often I get the impression he just pulls most of it out of his ass.

    I mean, there can be value in speculation, but I feel he should be clearly when he is speculating and when he isn't

    He is one of the few YouTube people I will actually watch, cause his videos have substance and facts, rather then bling and stupidity of most YouTube tech channels. Plus he likes to try to analyze rumors which can be fun, even if it's just a educated guess.

    Nah. They just want to hear what you think about his videos and how written text is so much better. At this point it's like nuclear Gandhi.

    Reminds of the DeathFromBelow's Mint rants. He used to have a lot of passion. You need to spice yours a bit!=

    Nice job on the bait to try to get me to get another off topic warning.

    You should ease it on the personal attacks or maybe you'll get some of those sweet sweet warnings too. :p

    His videos could cure cancer but i'll never know since I can't understand a word he's saying.
    I'll continue to get my chemo from the written word. ;)

    We must be watching different videos . From all I've seen, AdoredTV's info on sources, and what is speculation vs leaks etc, is above and beyond.

    Check your DNS settings... they may have been hijacked. That would explain a lot.

    Oh - :p

    That was a really good run through how cache works. This saved me weeks of my life. I can just point people to this when they ask how cache works, though I may need to clarify the difference between instructions and data.

    During the history lesson, I couldn't help but think back to the K6III-450 I had on an Epox MVP3-G5 mobo. The on-chip L2 at core speeds (think it was 256KB), plus the then-massive 2MB cache on the motherboard which became L3, was a revelation. Being able to run at 115*5(575) at decent thermals was nice too. It held it's own against the P3 Coppermine, which came out shortly after, though it had issues scaling much past 600MHz due to the really short pipeline (6-8 stages iirc). I was working for a PC component wholesaler at the time, warehouse schlub who labelled stock, so I actually got to stay late a few nights and pick a combo from a case of motherboards and a couple trays of procs. Even had an old guy complain to my manager that I was damaging stock, as he didn't really get the WC rig I had going. It covered the CPU, Chipset, and VRMs (this was a time when AMD and Intel were really pushing the limits of power delivery on motherboards). Ended up having to demo it to them, showing performance and thermal deltas, to explain what I was on about. Got me my first real tech job. Good times, I almost miss having to sweat a shroud onto a heatsink to make a waterblock.

    Hate all you want, his analysis is pretty good. It's obvious he knows how the underlying hardware works, plus he knows how code leverages that hardware. I'd say some of his rambling and reiteration are products of responses he got on past videos. He seems to gloss over stuff he assumed was common knowledge early on.

    I honestly find Jim's speech impediment to be soothing. After a day of listening to Aussies/Arabs/Slavs/Euros/Afrikaanis rant on the phone about how the change they just made couldn't possibly be causing the issues that just started happening, it can be a balm. If you think this guy is hard to understand, work a day in IT support. He's got nothing on an angry Aussie/Kiwi spewing tech gibberish.

    I hate the delivery method (it could be greatly improved if he had someone read the script w/a neutral canadian accent.
    And with text, graphs and charts you can get the same data and a better understanding of the subject matter in less than 14 minutes.

    The guy is teaching you something.Yet, you're concerned with how he talks.

    Wow. Just wow.

    Well, his chosen medium is video! If you don't like videos because you find them inefficient, why are you even in this thread? Did you not know it was a video when you watched it? Or what?

    And he has worked to reduce his accent, with success - though what thanks he gets for that I don't know. He'll probably never reach the holy grail of "neutral Canadian", poor guy.

    I agree with Skillz: the attitude is just amazing.

    Neutral Canadian accent? Wataya own aboot?

    So the food is good, you just don't like the spoon used to eat it? Get off your own lawn with that crap. (Though I recognize your right to your own opinion.)

    I've been told I'm too pretty to take seriously when talking tech or engineering, guess I should stop washing my face. The fact is, it would be hard to recreate how he presented it using just text and graphs. The way it's presented here relies on the visual/audible interplay. From my interactions with Joe Public, it would resonate in a way that would not only sink in, but spur inquiries into the subject matter. Sure, if you're already familiar with the concept of threading, caching, and the various bus architecture, it can seem long winded. But when viewed from a layperson's perspective, it's both comprehensive and concise.

    Again, I think most of the guff he gets these days (here anyways) is a result of Jim trying to reach a larger audience. When he started there were lots of requests to explain concepts and such he covered in his videos. Now he has to deal with people complaining that he explains and rehashes things. This is actually a basic principle in public speaking, at least in military training. "Tell 'em what you're gonna tell 'em. Tell 'em what you're gonna say. Then tell 'em what you just told 'em." If you're speaking to Enlisted peeps, then you can expect a fruitful Q&A afterwards. Officers are expected to glean any and all facets from your presentation, so everyone has time to have drinks at the lounge.

    Hard to understand for many here, but sometimes your comments are not required to foster intelligent conversation about the topic.

    If you look on YouTube, Richard Feynman gave a lecture in the late 70s to mid 80s basically saying the greatest strength of computers is their ability to move data around, not necessarily compute the data. Looking at how much cache design impacts performance, computer scientists really had it nailed down back then.

    I honestly find his accent perfectly simple to understand.

    If you can't grok it, the problem is you, not AdoredTV, and he's under no obligation to change it for the sake of your faulty hearing.

    So up next for AMD:
    Ryzen, plus 16gb HBM, no DDR4.
