Things were heating up here in Southern California, and I'm not talking about the Heat wave.

I'm talking about all the discussions regarding what's coming coming out of e three, whether it be gaming consoles or, of course, PC hardware, because AMG has obviously stolen the show with the amount of news and press releases and all that sort of stuff now, Yes, I'm aware that this is right on the heels of the last video we did about radio on, but I think there's a lot more to talk about.

We've done more research, and we got to have a finally have a meeting with AMG engineers and talk to them specifically about some of our questions or concerns, which I've seen parroted in the in the comments section of a lot of the video.

So we asked him a lot of those hard fact hard facts, the hard questions we got some information on, and then also kind of a new perspective of how the sort of look at the 5700 X t and the 5700.

So let's go ahead and talk about that with their nine bleed designed the scare on DRG be fans for metallic gear offer a balance of performance anaesthetics available in both 121 140 millimeter sizes.

The scare on fans are sure to fit any size builds.

Hub mounted led is provide a widespread of lighting, while the daisy changeable wiring harness and cherry tidy wiring job every time to learn more about the scare on our G B and D RGB fans from metallic gear.

All right, so let's rewind to August of 2018 specifically, Cologne, Germany went in video, launched their R TX lineup of graphics cards.

With a 2070 kind of thrown in the mix there a little bit and they're here was the response, and this is a totally justified response.

But this was the general response from the public.

They cost how much you're getting 20 to 30% more performance over pascal t t t i.

But you're getting it's costing you 40% MB or whatever.

It was 50% more something crazy like that.

The general consensus was gamers want performance they want Hi F P s low latent Cee Lo Response times.

So turning on a fidelity feature like Ray tracing at the cost of 50% arm or F p.

Anyway, there's been some optimization sze, but still it's It's a performance tax.

No matter what the audience said, we don't care about DX.

Nine months later, now to June of 2019 at E three, Andy launches its new high end gaming cards not to be confused with the enthusiast level, which is where the Vegas stuff and, like Artie X kind of resides but a high end 5700 x t in a slightly lesser high and 5700 featuring 17 nanometer Naveed technology.

On the new are Deanna architecture completely different from GCN, which stands for Graphics Court.

If you didn't know the most common thing we saw, even though it was on average $100 less than its direct competitors from in video and give you anywhere from 2 to 21% more performance in gaming was wears the Arctic.

Nah, V, you were supposed to save us, so I find it kind of interesting that the audience back not even a year ago was and even just last week we did a video about the quick to Artie ex update was no one cares about this crap.

But then there's so many people out there that are like, What the hell?

Why doesn't have DX are so we're in this weird kind of a limbo space where you have to make this decision.

Do you want Max performance or do you want Max Fidelity and my fidelity?

Soft shadows, the obviously d x r ray tracing for Lightpath, all that sort of stuff.

You have to kind of take your pick, because right now we are on the cusp of the next gaming revolution, just like we were nearly 20 years ago when rationalization came up.

We're we're on the next generation of the weight games are going to be performed.

So I asked this question specifically When we had our meeting today with a M D.

X R is not something that was mentioned outside of the consul space?

Because that's the other thing that confused a lot of people was like, Well, wait a minute.

If project whatever it's called for the new Xbox Scarlett, if it's going to have eight Cade capable gaming and it's gonna have Ray tracing and it's an AMG pew for AP, you technically, why the heck is the PC space not even mentioning it or talking about it when that same these bread and butter.

So I asked them that very same question and the general consensus here.

And of course, this was a lot of like not off the record.

But this is off the slides at this point, because there's this was not a specific forethought conversation that was supposed to be had was that Ray tracing does indeed need some maturity and not with the architecture which obviously needs to happen.

I mean, in videos doing it through tensor course for Del SS, and that's a super sampling, right deep learning super sampling, and then it needs to be also optimized in the Ark Artie course base, which is what's happening with all the ray tracing calculations.

All that math is being performed on the arty cores, and then the coup decor is handle all of the other post processing and know that sort of stuff.

So we've seen a good first gen implementation of it in terms of the fact that you can't even do it in real time, was already kind of the wow factor, and then doing it at 60 f.

S is already great, obviously at a huge cost of $1200.

So $1200 for 60 F PS, regardless of how good the scene looks, seemed like a huge step backwards to gamers.

So Andy made the conscious choice of targeting where most gamers reside and that is going to be in the well.

The 16 57 100 are indeed high end cards, but it's going to be in that range and down.

To be fair, I think most gamers they're shopping around $250 if you want to spend that kind of money on the graphics card you're still gonna be stuck with, like the art Rx 5 80 Rx for 80 or well known at the 45 85 70 or even a 5 90 But you're not gonna obviously be getting any of the new RD rd and tech architecture.

The best way to kind of look at this is the way risin first gen like the 1000 Siri's wasn't so much a game changer as much as it was a disrupter.

It's referred to as a disrupter because it was designed to just kind of make people kind of go woah!

Risen came out and the market share started to shift.

Intel's market share gains stalled, and then AMG gained back CPU market share.

All the intel was still the dominant player.

AMG gained back market share and then Zen to now giving us the amount of increased we saw on my PC and now beating apparently core for core intel.

See pews at in much lesser price has changed the sea few industry This is what a MD is banking on our d n a being for graphics.

This is first Gen rising for graphics cards.

You're not going to see the disruption necessarily happening right now, but what you're gonna probably see is a lot of people adopt that whole wait and see attitude.

And as long as a ND can live up to the promises of, we are going to be making this as good as possible over the next several generations and generations.

I don't mean we're talking five year plan.

I mean, we're talking three year plan, probably at this point.

Then what you'll start to see is a much broader spectrum of competition taking place across the board.

But like anything else, you can't get there without launching the initial disrupter in the first place.

The other thing that the reason why they didn't launch this high end God's saving Sadio save the gamers now the architecture which everyone thought was gonna be coming out don't remember a year ago, we heard that there is going to be a r T X killing card for $250 from a M D.

Well, the Internet sort of made that up on their own.

You cannot find a single piece of information where MD even speculated or hinted at any sort of performance for that for that dollar range whatsoever.

But what am D has decided is that the raw performance is more important than the eye can.

But at the same time, what they found was more important was that you have backwards compatibility in terms of the tool kits.

And because GCN is so matured in terms of being in the consul space in the PC space, in the cloud space as well as mobile, it was.

It's easier to implement and get the technology out into the wild by making sure that it's backwards compatible with all of that, while featuring forward compatible technologies as developers come online for it.

So they adopted what a lot of people said in videos should have done, which is the adopt now and then.

In six months to a year, these features will become available because of the fact that you know it's gonna take time for our T X and the ex are to be implemented by the developers.

They decided to build a graphics card on a new architecture because as much as people want to say our DNA is just a rebranded gcn, it's not.

The difference is that it's ground up different with 100% backward support our backwards compatibility support so that allows you to have a much broader spectrum of adoption of this particular card in terms of game is being designed for it, while also utilizing forward facing technologies that are only gonna be available on the nappy based architecture.

That once the adoption rate improves and more Navid card, they're out in the wild.

Then you're going to see features come online later on in games, whether their new games or updates to existing games.
