Very interesting. This doesn’t really happen much on newer systems, especially with higher bus speeds , latency is reduced. The lesson is, it is what it is. ;)

A computer work station is becoming an increasing part of my life productivity now and using these machines for work is requiring me to know more about configuring and building them for my specific applications.

Small addition, but I think worth noting (can't recall if Linus has addressed this in the past or not). Frequency in and of itself only has a linear affect on the power needed by a cpu. If the only thing that changes about the cpu is the frequency, the power will go up, but not as much as you might think. It's the fact that higher frequencies generally require higher voltages in order to remain stable, and changes in voltage have a quadratic effect on the power consumed and outputted as heat.

The 4790k ran games slightly better with HT off, but disabling cores offered no extra OC potential. The 4790k died in a lightning strike, and was replaced with an R5 2600. I can get a slightly higher stable OC with 3 cores disabled, 4.25 GHz, but the stable 4.125 GHz I get with all 6 cores is fine.

The main reason is that most software can only process the next task only if the previous one is already done (if this then that algorithm) Like in games, you can't predict if the player will press W, A, S or D unless the player have already done so. However, in video editing, it already has all the frames and all the effects on the table, the first core can process the first frame and the second core can process the second frame and so on (where more cores = more frames being rendered simultaneously) since it already know the steps needed to render the video.

The comment section can only communicate with one meme.

Also, the OS's overhead and ability to manage processes/threads can hurt performance when juggling more CPUs and Cores. (Especially older kernel models that saturated the first couple of cores to manage the threads and locks to other cores.) In the mid 00s, more than 8 Cores/CPU was hard for Linux, as Linux's Linus famously discussed at the time, as there were not plans for the general version of the kernel to perform well with more cores. (Which has since changed significantly, but was an interesting blip in the history of the Linux kernel.) With NT (Windows) version 7 received a huge update to the kernel to eliminate most of the overhead when working with 64 or more CPUs/Cores. Windows 8 & 10 received another large set of scheduling optimizations and capabilities for multi core performance. For example, additional information is considered for each core and what threads to use, thus being able to schedule cores based on location, stability, and temperature. This is the reason the XBox One originally had more stable frame rates than the PS4, as the kernel was able to thermal balance threads on the SoC - which was unique to Windows NT at the time. There are still a few scheduling advantages that are still unique to Windows 10 (NT) - with GPU preemptive scheduling, and processor agnostic scheduling being the two most known. The second one meaning Windows can send threads through any cores/CPUs, GPUs and co-processors, even if the code wasn't intended for that processor or type of processor.

Just to be clear, AMD's new EPYC Rome CPU's are addressed as a single numa node in the default configuration, with performance gains of around 10% possible when splitting it to 4. That's quite a bit different to the previous generation

This video completely failed to mention Amdahl's law. There's a hard mathematical limit to how many cores you can make use of. It's not just a current technological limit. It's a limit that cannot be overcome for all time. If you're running a single application, having the inevitably sequential part of the computation be as low as just 1/32nd or 1/64th, is borderline impossible. Of course servers that are hit with loads from multiple users that run independently of each other can do with even more cores, but a personal computer with more than 64 cores will maybe never make sense.

This is true but somewhat misleading in the sense that there’s no actual limits on how much of a program is sequential. Even things that seem like they must happen in order, like calculating the digits of pi, can be easily parallelized indefinitely.

Did Intel come up to Linus in a black van and smack him around in response to his rant last week?

Please explain: *NVMe Host Memory Buffer* . Some "budget" m.2 ssd uses (the CPU's) HMB instead of it's own DRAM(if I'm understating it correctly). How does it work? And how much difference it makes with the ssd's (usually) SLC buffer? Thanks in advance.

Please do a video on Intel different "lake" series cpu, it will help viewers decide on which chipset to buy for their laptops.

Linus were u in Amsterdam recently?

Yez with me

Wait a minute! Hold on a second! Don't move! You're saying the moral of the story here is to buy for your specific needs? What?! So I guess I didn't need an EPYC to play Shadow of the Tomb Raider after all. Well WTF?!

2:04 and I thought everyone had forgotten about that 🤣

Before I built a new system this year I done some research on the frame rates between single core and multicore when gaming and many games don't even support multicores for gaming and those that do, there was very little difference. I am a casual gamer and I am happy with a moderate frame rate, enough to keep things smooth. I mainly wanted something to improve my Blender renders and that will use all the cores you have along with the threads so I ended up going with a comfortable, and affordable Ryzen 5-2600 which has 6 cores / 12 threads. It definitely pays to research this stuff online here and and in gaming benchmarks etc. I done a ton of research for my system over several months and what I ended up with is very nice and I kept the costs way down.

On the flipside, it is quite possible that with the next generation of consoles using Ryzen-style CPU's, games might begin to take greater advantage of more CPU cores more regularly. They will probably have to if they want to ensure consistent performance.

@@Diviance Not nessecarily. CPUs in modern games are not relied upon as heavily as they used to be in the past. I did some 3D programming myself and these days the GPU (video card) does most of the heavy work. 3D programming changed so much in the past couple decades, I had to relearn modern OpenGL as now you load in shader programs, which are programs that are sent to the video card, it then compiles them on the fly for use with the video card. You then send your 3D data to the video card to be processed and displayed. A lot of math is done on the GPU now and video processing like what you watch on KZread. This isn't going to change anytime soon. If you want to improve your game performance, you could probably keep your current CPU and buy a better GPU and you will see a huge jump. In fact, I actually did this! I had a ten year old system. An old AMD triple core CPU, no hyperthreading of any sort and 12G of RAM. I had an old video card, a GTX650 which was newer than 10 years. I was in the process of building a new system (which i am on now) and I bought a GTX1050ti and started to use it in my old computer with the 10 year old CPU right away and immediately was able to run games that I had a hard time with at very high settings. My CPU is now an AMD Ryzen 5-2600 with 6 cores/ 12 threads. And it helps due to the much higher clock speed (3.8GHz overclocked slightly). My main reason for getting it was to use the 12 threads in 3D rendering with Blender which will use it. And the CPU's speed was nice for gaming for a good cost. If you want to improve your gaming, don't look for more cores but look for a CPU with a higher clock speed. Because games don't use multicores as much, a higher clock speed will net you a MUCH greater frame rate. In fact, I have seen tests people have run on single core speed ratings verses multicore on games that support it, and the difference was very small, and even worse on multicore in some cases if I remember. If it's for gaming, look for a higher clock speed over more cores. Save your money for a better video card instead of a multicore CPU. If you're doing 3D rendering than that can benefit from both multicores and a good 3D card. Blender just added support for RTX video cards as well (real time ray tracing).
