Is this even possible? There was a major update since then, so it should not even matter which patches were installed before.
It is possible if you killed windows update. AFAIK only possible on anything below spy10....

:palm: How this is even related, all you need is some JavaScript running in an ad you see while you are visiting some website including eevblog.

As for the PSU:
http://www.realhardtechx.com/index_archivos/SILVERSTONE_Essential_series_ET650_B_650W_4.html

Its as bad as it gets. 8pin Protection IC -> usually no OCP on any rail, no UVP on +12V either.
Capacitor Choice doesn't look that good with JunFu/CapXon
Since I don't think there is any AVL from Silverstone for Cost Reason, it is possible that some units might even have ChengX capacitors - like my CWT GPS-750V has...

I was surprised by the PSU, it looked bargain-basement level to me.

Dave's normal obsession with quality capacitors seems to have gone out of the window on this one.

In his use case, the intel platform would be better, and the main thing I would change on that system, is the heatsink. He should use at minimum, a NH-D15, especially since he will need to overclock that CPU to get the most out of it.

GPU encode needs the fastest possible single threaded performance or the GPU encoder will get stuck waiting on a single thread to feed it.
He's not using GPU rendering. Besides GPU rendering is limited (in terms of supported settings) and the lower quality of the final product compared to CPU rendering.

https://youtu.be/APvuMPGswug?t=1640

If he is doing what he did in the video that he made and recorded, then a higher clock speed will increase the encode speed, and like in the video, he did see an improvement.

Nvenc only has 1 thread that prepares data for the GPU to render, thus everything will get held up by that single thread. The application will use multiple cores, but the task that is most important, is left with just 1 core. If he could control which core that nvidia encoder thread fell on, and overclock that 1 core to 5GHz,he would see a large speed increase.

If he is relying purely on a CPU encode, then threadripper would offer better encode times, but other aspects of editing will suffer, especially if he does tasks that are traditionally single threaded, such as camera tracking, or if he tries to do a special combination of color grades that cannot be GPU accelerated.

Possible if you killed updates completely. Which means you don't care about security at all.

Where did the video go?  I watched 1/2 of it a few hours back, came back to watch the rest and it's gone.  Who's copyright was offended this time?

Dave may have done some further editing and is uploading the new version.

I suggest trying again over the next couple of hours or so...

No, but you're a lot safer.

Disabling updates is compromising safety to begin with. Then NoScript to somewhat half-assed solution.

And much more annoying, not less (for less annoyance there is adblock). You'll find like half of the websites don't work or work incorrectly. And every time you'll manually enable scripts, you'll compromise security. I disable scripts myself sometimes against very annoying news sites which want you to pay subscription but allow reading the thing with scripts disabled. But every time I disable scripts, I find that almost any other site is broken.

What a BS claim, 99.999999999% pulled out of from thin air, there are not so many people on the earth for that figure to make sense. And this tool does not test against meltdown which is the most dangerous.

Seems like the video is up again at the EEVblog2 channel..

I think there is little point to go the i9 series processors on the Intel platform. Then at that point I think a threadripper is way more cost efficient. The 7900x is literally 2x more expensive than the 7820x, for only 2 more cores (which are also clocked a bit slower).
This benchmark suggests it's a pretty linear increase in speed of about 20%, for 100% more cost (but less on total system cost though).

In terms of comparing it to AMD offerings, see same benchmark. The AMD 1800X is nowhere close in h265, the 2700X is an incremental improvement (add a generous 15%), so same. The 1920X is 22% quicker in h264, but about on par as the 7820X in h265. So it's about even I guess.

I assume this is also Dave's workstation at the office, in that case the faster single-core performance of the 7820X should also be taken into consideration. There the 7820X scores 194 in Cinebench single-thread, vs 167 for 1920X/1950X..

I think that in terms of buying equipment as a desktop, then this is key. Although multi-core performance is nice to have for that 22% h264 boost, this is something you could fix with a next gen upgrade or getting a more expensive CPU. The single core performance for daily tasks is something different altogether. However it's hard to guess where CPU land is going to be in 2 or 3 years time. It probably won't be making much improvements in single-core performance though, so it's nice to maximize what's available.

Threadripper gen 2 is already announced for launch end of this summer I think. Flagship is going to be a 32 core 64 thread monster, but I doubt that will be priced as competitively as the 1950X was. Personally I think they will extrapolate the current pricing scheme, i.e. you will still get more cores for less money than at previous gen launch, but I doubt that they will put out a 32-core chip at 1000$, such that the other skews (12, 16, 24?) will be priced accordingly..
I'm planning to upgrade my workstation somewhere this winter, and key for me would be to see what the ST/MT performance vs pricing vs core load will be..

But if you're only doing GPU accelerated rendering, then probably the i7 is plenty..

Daft CPU, silly flashy RAM, and cheaping out on motherboard and PSU.

Oh well. Lead a horse to water and all that.

nonsense, we're engineers. Threadripper is objectively a much better part for a video encoding machine.
Exactly.

Apart from the fact that the CPU is not doing the encoding.

I do care about security, but i want to decide when to update and i do not like my PC restarting on me. Usually i put my PC into sleep mode with a ton of stuff open, i would be pretty pissed off if it would restart because "security".... BTW just because you dont install updates it does not mean you are not safe, the last updates i installed are from 2015 on my win7 partition and interestingly i didnt got any kind of crap on it(it was my main OS up until a few months ago). Contrary to what you believe the reason for disabling updates is not the lack of care for security, but because i care. MS used the update system to spread ad and spyware onto older versions of windows, and they fallen so low that they marked some of them as security updates.

=NoYoutube and NoManyMore. If you leave scripts enabled for any single website, you are not safe because you can stumble on malicious ads anywhere.
You can enable them on a per domain basis, and with adblock you can do it even on per script basis.... Its not convenient? Yes, but if something is more secure its always less convenient....

I would have gone with Threadripper, because this is exactly what it's made for.

No, it's not. It's made for instances that can make use of large numbers of threads, and that isn't the case in my workflow. The CPU isn't doing the rendering. And Vegas doesn't really make use of it in general.

The CPU is still decoding the source and funneling the 4K data to the GPU.

When did that become a 16 thread problem? Decoding is fast and, well, DMA.

CPU runs at under 60degC when rendering (overclocked). 70degC on 100% all cores loaded. I wouldn't say that's something that needs fixing.

I never said it did. In fact I believe it's a single thread operation in Vegas. Hence why Threadripper is not the best tool for the job here.

Don't mind the Noctua fanboys. The Hyper 212 is, although not the best, almost without doubt the best value air cooler on the market. Unless you're using one of the old AMD 220W space heaters it's an easy choice.

.. well I asked you specifically why you picked the monster 16-thread i7, and that was your answer. Note I never suggested Threadripper, either..

So many websites will be broken, it does not even matter. Websites are not controlling what ads they show, so leaving some websites with scripts enabled makes this practically meaningless.
