Use alcohol to check where the hotspot is (a trick from Louis Rossmann). I guess an alternative is finding a schematic or figuring out enough of the power network, then going there with a multimeter checking as you desolder stuff. Beware that GPUs do have low resistance between power and ground, a short may not be a short: https://xdevs.com/fix/oc_z_pc/ Get creative, use a PC PSU, put a resistor in series with a voltage output (maybe... 50 ohm or 5 ohm on the 5v line to keep it simple, just be careful with the resistor max power rating) and use that to inject something somewhere.

Just seen the RX7600 XT page, I'm stocked.

They lost the opportunity to win the 2024 worst step-down converter award

I think that this ship has sailed, connectors make up most of the cost of a PCB (excluding cpu/gpu...), soldering RAM lowers the production cost, likely skips an assembly step, lowers power consumption and allows faster speeds. It is a tradeoff that incindentally chokes the "upgrade path" of the very fews. Maybe at some point RAM will be directly soldered above of below the digital IC and in its place there will be a fast, dense non-volatile memory in a DIMM format.

I do not know where I've heard it, maybe from MLID or Techtechpotato, I think it is microsoft that is requiring a certain level of AI performance to OEMs. Look at the snapdragon elite X, it reports 45 TOPS from its NPU, AMD has similar 39 TOPS. Intel I do not know. See https://www.digitaltrends.com/computing/amd-ryzen-8040-set-up-to-fail/ https://www.counterpointresearch.com/insights/qualcomm-snapdragon-x-elite-arm-based-soc-windows-ai-pc/

I do not understand why someone would prefer to browse twitch for partially or poorly censored porn content instead of just going to another website and enjoy the real deal. I understand what Luke and Linus said during WAN show about the "least amount of friction" principle for website viewers, but this would apply if the content had been the same. Being equally free, why watch the "worse" version? I instead see creators getting more eyeballs, advertising themselves and the platforms where the content they make is completely fine and allowed. So I guess... either allow everything to try to steal traffic from porn websites, or make rules stricter (and enforce them), I'm not seeing the point of this half-way compromise. What do you think?

That is not variable, as others already said here. Buy a kit of fuses similar to the ones already on the breakout board, shorts may happen and fuses will blow. Having spares helps, just choose reasonable values based on the max current that the PSU can output on each rail (+12, +5, +3.3, -12). If you need the output to actually be variable (that is, you need to output for some reason 9V or 6V or anything that is between 12V and 0V) a potentiometer will not do anything for you, you need something called a "regulator", linear regulators are simple and produce a clean enough output. Imagine measuring the output voltage value over 10 seconds: a perfect noise-free voltage supply doesn't exist, but on such a supply when you measured voltage, you would see exactly the set value for any period. A noisy supply's measured value would fluctuate continuously around the set point. If you could hear it, it would sound "noisy" - the perfect one would be "whisper quiet". Be a bit careful - PC PSUs can provide a lot of power and you can easily blow things up if you make mistakes (and they do happen). In a short circuit, these can generate significant heat. This is another good reason to use linear regulators like the LM317 - their max current output is low compared to the PSU. If you make a mistake, the LM317 will limit current and/or go into thermal overload rather than destroying the rest of your circuit or breadboard. Checkout the LM317 wikipedia page, do not bother with anything related to DC-DC converters or switching regulators. Read an LM317 datasheet, for example this one from Texas Instruments https://www.ti.com/lit/ds/symlink/lm317.pdf , there will be many things that make no sense to you but the paragraphs 3, 8 and 9 will give you a few ideas of what this component does. Checkout the eevblog forum and youtube channel, you will find a lot of discussions and explanations (and bickering) about linear voltage regulation. The best advice would be to just grab a book, The Art of Electronics by Horowitz and Hill, especially chapter 9... but once you have the book, you can just read and learn there what you need and you will be satisfied by it.

Can you build on the work done in this video to further destroy audio gear myths? The amount of mics tested here is huge, the method is quite scientific and he even tested different diaphragms mechanical features...

Making your harnesses public is just amazing. People wasting their time doing tests by hand had to stop a long time ago, this is another great thing done by LMG that will improve how reviews are done for everyone. I hope that other reviewers/organizations also will contribute to the repo instead of just using what you've done.

Suggestion: Create a Reference Guide for Review Metrics Hello, I know that maybe this post should be in the other huge thread that is full of of angry people, but I think this is more a suggestion/request for the Labs team. This is really just a long example about GPU testing because that's what I'm thinking about now, but it can be applied more broadly (I think). In GPU reviews, testing used to be simpler - just FPS in some games, thermals, power draw. Then we got more advanced metrics like noise levels, min/max/average FPS, 1% lows, frame times and many others will come for sure to even better understand and evaluate a product. For example, I saw a recent GN video explaining a new Intel tool to measure "GPU busy" and driver overhead. They spent ~30 minutes just on what the metric means (I'm sure they could have made a shorter version with less chatting in between slides). I understand LTT has to target a broad audience so hard concepts/metric often get simplified, have to be omitted or maybe just belong to written form. But even current metrics like 1% lows aren't that intuitive, you can explain it as the lowest 1% of FPS values, but that's hand-wavy. The lowest 1% FPS values are... what? A range of values expressed as a single value? Well kind-of, you get what I mean, higher is better let's just move on. The underlying concepts of cumulative distribution function and probability density functions are not easy, sure in an academic context this is just offensively simple, but it is my belief that these concepts are not well understood elsewhere. I think that if I go point blank (very mean of myself, I know) asking reviewers online to explain (without handwaving) what a percentile for a probability distribution is, I'd get many "uh... ah...". I'd not fault many of them (depends on what follows after the "ah...") because while it is quickly defined in a math context (a simple inequation of the inverse CDF, child's play!), each of those words carry a great amount of "meaning" and, as it often is, an easy math concept is just an elegant and concise way to express a deep and complex idea. This 1% low is just the best example I have to pitch my request, I hope I've shown what I mean by not an easy concept. Here is the suggestion/request: I'd like you to make a reference "guide", somewhat similar to the definitive guide to build a PC, as a reference for every metric that you wish to publish, going into "enough" details. The goal is to educate us viewers so we better understand these concepts instead of relying on vague explanations, to have a good reference to be pointed to or to refer to when needed, to clearly understand what it is that your numbers actually mean. With this reference, you could start publishing even more complex metrics (like the gpu busy example above) since people will understand them. It will raise the quality of discussion even more. We are already way past the "it goes faster it is just better" with most of what you review, and most of us (I think) had to adapt a long time ago to the idea that there is a need for many metrics to understand GPUs before buying one, it already is a higher quality of discussion than what can be found in other fields. Adding to this, if you could show us how you found the errors you will be correcting in older videos, this may lead to better feedback from the viewers, as we will also know better what to try to look for or have a better way of looking at the data you publish, instead of just staring at it (sure, my fault I sometimes do stare). Even reading a chart is not exactly easy, it is not just a bunch of lines thrown in a rectangle, otherwise there would be no need for someone to comment them. Maybe a better understanding of the various metrics from the viewers may also lead to better feedback when errors crop up. I wish you the best of luck with all your endeavors. I believe this team will continue improving LMG content regardless. Even though it may not pay wages, I appreciate what you've done over these many years. I hope you will get back on track as soon as possible, as I believe you strive for the goal Gary once stated to "not be questioned" about Labs data.

How would you compare Terasic's products to this Zed (Zybo?) board? How is a Cyclone V in that DE10 board compared to a ZYNQ-7000? I'm more familiar with Altera's tools and docs (and... let's just say that I'm quite displeased by them, maybe I'm asking too much or I've yet to see how worse it can get). I clearly see that a Cyclone V has 110K LEs, and the Z020 85K logic cells, but are they similar enough that one can just look at this number? Are open source communities/tools more geared towards xilinx products? What do you think can be cheaper to obtain but still good enough with I/O and resources? I myself have seen that even an old MAX10 device with 50K LEs can do a lot, and that does not even have a builtin ARM core...

I do not know why I stopped noticing the outro theme, but this time I noticed it. I think I had forgotten it, but man it never gets old. Too much infrastructure you've become too big.

I think you have shown one more time how this is an amazing company to work for and how a good business owner should think and treat their employees. When I saw your tweet I was puzzled seeing old videos in the cannel's homepage, then I realized that a new video talking about what happened would be available soon and that something to be learned was going to be in it. Thank you.

Thanks, this video gave me a different perspective. None of this information is new or at least I should know most of it, but I've always narrowed my view to the "nearest" products (meaning the current vs previous chip, across the two manifacturers, in a reasonable price bracket), seeing it all in one place does make a difference. Even if this video is focused on nvidia, the thing that stuck to me at the end is that (to me) it looks like amd's gpu division is alive by miracle.

Yes, Fine Wine! It's been quite a long time since I've last heard of AMD's Fine Wine tech, Intel should just license it from AMD
