so clearly there's a lot of construction going on outside of our old set.

We're building our new one, so we're kind of in the shooting position right now where it's noisy, no matter what we do.

But until our set is done and they're done, we get to deal with the noise and being semi homeless.

We're gonna talk today about the new vulnerabilities that are going on with Intel processors, but we're not gonna talk so much about the problem.

We're talking about the potential effects of the problem on your day to day.

And then we're gonna kind of test whether or not disabling hyper threading Onley affects our performance like 7% which is what Intel is trying to make you believe.

Theme newbridge PCU cables from cable mon fuse to separate PC I'II cables together with a single close comb.

For an incredibly clean look, you can configure years however you like using their easy to use configuration er and from now until May 27th you could take 15% off your order using the coupon code.

May 15 This coupon code is good for absolutely everything on the cable mod global store.

So if you've been looking at pimp you rigged with cable mont gear, now is the time to learn more.

Okay, So, like I said, we're not going to talk a whole lot about the problem itself.

If you guys want to learn more about this new vulnerability, it's called Zombie Load, and it's specifically affecting like predictive computing.

And so that is going to specifically be dealing with intel.

See pews and hyper threading, and you can drill down into that Mauritz.

It's called MDS, but you can drill down into that more if you go and do some searches.

But what I can tell you the problem regarding this and zombie load is the fact that it could be affecting clouds.

How much information have you sent to the cloud?

How much data have you ever just connecting to the Internet?

Your information is in the cloud packets are sent packets or received, and so we have server farms and data farms and all that that could be potentially affected by this, So that's a whole different level enterprise solution that's gonna have to be figured out in terms of patching and EMC, you are micro code updates.

And before you, my average viewer is going to be general use computing, maybe some video rendering or live streaming and gaming.

So today we're gonna do some testing on both hyper threading, enabled and disabled on our 8700 K.

Not our highest NCP is that we have because we want to kind of try and keep it sort of realistic to the real world.

So this is more like a 10 80 attended t I and I guess, technically not really lower than that.

What we want to see here is what the impact would be like if you wanted to take the extreme measure of protecting yourself by disabling hyper threading.

Now, like I stated earlier, it's a really convoluted, complex problem that I don't know what the solution is gonna be a long term on that don't think Intel does either.

But they made a statement that it's okay you can disable hyper threading and you'll lose like 7% performance.

Well, it's kind of funny, cause Apple said the same thing.

Only they quoted 40% of a performance loss.

So I'm kind of curious is what that number really is.

We're gonna test that today and see what the real impact is gonna be, too.

That's only like a 300 megahertz over clock on all course.

So this isn't out of the box performance.

But like I said, what we're testing here is what the bottom line?

What did we lose performance wise on my rig by disabling hyper threading.

So, obviously, your results may vary depending on your motherboard.

If you have a hyper threading CPU, you more than likely even on a like a aby Siri's motherboard would have the ability to disable hyper threading so you could test this on your own.

The flip inside the bios, of course, each bios is gonna be different.

I'm gonna go ahead and ah, let me do a three d mark run.

Mark is the fact that it gives us both a physics test, which is CPU, and it gives us a GP test, which is obviously high frame rates, which seep.

We see it all the time, especially when we're doing like our our high, eh?

Ellen to cooling benchmark runs that the sea few does indeed affect the graphic score.

So that is what we're gonna test for sort of our baseline there.

Um, probably a Senate bench will do a Senate bench run as well, and we're going to do time spikes.

And we'll do regular times by We'll just kind of do some tests and then we'll just disable hyper threading and do the same death.

The very first test that we did everything is on hyper threading five gigahertz and all that.

No over clock being applied to our graphics card.

There's no afterburner running any of that.

So we've got a graphic score 50 to 23 a CPU score of 36 45 for a combined score of 49.

04 Now, we obviously know when we turn on hyper threading it's gonna go down.

But anyway, there's our base Mark our baseline 49 04 with two individual scores.

So let's see what Cinemark gives us or cinnamon Cinemark bench, whatever.

Imagine if they just combine the two tests.

Right now, I'm not gonna go through the scores.

I'm just gonna show you which ones we did, because what we're going to do here is we're gonna put them in a graft format.

We care more about how much performance we lost, rather than what the actual score is that we started with because when we end up with this kind of the point here.

So we did Senate bench ar 15 with hyper threading on all 12 cores.

Six course, 12 threats doing their thing at five gigahertz.

We did times by extreme and regular times by because they both respond very differently to workload because it's this is technically a four K test versus a 10 Ap Test or 14.

Metro critics in again no other clocks to the GPU.

So we want to see what happens to our average frame rate because this is a high frame rate game, 208.9 frames for seconds.

Once we cut the that workload, potentially in by 1/3 I'm hyper threading.

People think like doubles your performance.

And we also did shadow of the Tomb Raider in both 10 80 p and 14 40 mostly because this is a very CPU central game as well.

So we also did a premiere of Our Kingpin video.

So we did a premier render with the 9900 K.

We're doing this on Phil's test bench, and then we're gonna re render it or edit rate whatever.

Yeah, it's a test bench today, and then Phyllis gonna also re render it with the exact same settings and same export settings with hyper threading disabled.

So those are our test, so let's go ahead and disable hyper threading now in your particular motherboard, it's going to vary.

We haven't a snooze motherboard here This is a strict Z 3 70 R Z to 70.
