AMD demonstrates Ryzen 9 5900X prototype with 3D V-Cache stack chiplet design

[jigger]

How can they have the gaming crown with an unreleased CPU which hasn't even been independently tested yet?

RIP Intel. For realz.

TBH, even Dave2150 would struggle to overstate what a crushing this is for Nvidia.

Currently waiting for the Dave2150 and g67575747382 thread.

4 months? Please cite your world first on that

Lisa Su said Spring which starts on the on the 20th of March and ends on 21st june. So the earliest it'll arrive is 2.5 months and the lastest is 5.5 months so 4 months is the average time frame.

you seem nervous, relax, everything is fine.

Lisa the gracious.

Not denying that. I was replying to a quote that specifically mentioned yields and heat and was mentioned as a matter of fact. I wondered if there was proof of this? I ask because the HUB video linked it directly to the speed of the V-Cache.

I don't buy the speed of the cache argument from hwunboxed especially if AMD are running zen 4 ES with the cache at 5ghz.

I reckon it's more to do with power budget and once those limits are removed it will clock as well as any 5800X.

That was about a week before the CPUs came out and they were independently verified a couple of days later, the 5800X3D isn't out for around 4 months yet.

And before that there was all the CPUZ and Cinebench leaks that came weeks in advance that was enough for some to declare it the "Zen 3 Killer" or "AMD is Dead". You cannot have it both ways. If AMD benchmarks are correct then ADL was short lived but i agree independent benchmarks are needed first

 

[Twinz]

It's more likely that AMD are just binning the chiplets to higher margin products, in other words EPYC, since this is where they make the margins.

Except they are apparently still selling 5800X parts that clock to 4.7Ghz.

You do know the 3Dcache is on top of the CCD, so it is a completely different part from a manufacturing point-of-view. They will be binned suitable for EPYC, suitable for desktop etc. once they have been finished and tested. Not sure why the GHz matters at all *shrug*

I think its also down to cooling. The higher the core clock,the higher the voltage required,and more heat being passed through the cache layer which is another barrier. So I suspect to keep everything within reasonable temperatures,AMD dialed back on the voltage a bit.

CPU Z and cinebench leaks are generally more accurate than gaming benchmarks though where a lot of variables can come into play depending on how the system is configured, the ram speed and the GPU etc none of which were shown in the slides.

We were discussing the decreased clock speeds on the new 5800X3D vs the vanilla 5800X. Clock speeds are measured in GHz.

 

[Twinz]

The same way everyone claimed Intel had regained the gaming crown after Intel released their internal benchmarks pre release.

I for one didn't think Intel had the performance crown until they were independently reviewed.

Right now, Intel has the performance crown.

So you don't think binning has anything to do with clock speed then? The cores that can produce the least heat, or highest performance with least voltage go to the best parts that have stricter need for TDP adherence. AMD clearly just want to advertise 105w TDP on 5800X3D (142w boost) and not worry about silicon quality for a single desktop SKU right now, so why go to the effort to have to use highly binned parts to hit 4.7GHz, when then can bin lower and still achieve the advertised performance. Just like any CPU though when you buy at retail silcon lottery will pay a part, and you might well find some parts go well beyond 4.7GHz. So the point still stand the increased cost of production means they'll be using the lowest quality parts they can get away with using to kep the best parts for the higher margin products.

 

[ltron]

GN just said totally different.

HWUnboxed asked AMD directly and they said the 5800X3D is the only model coming. See their latest video.

5800X3D: 8c only, who cares? It's not even worth an upgrade from a 3700x if you game at 1440p or higher.

Binning involves *multiple* metrics. Clock speed is one of those metrics.

I'd imagine there will be quite a few people on here that offload their 5950X for one.

You would have to be high to say something like that.

If it's anything like AMD's prior claims it'll be a win in very select titles with very select settings.

Yep, only certain games benefit from more cache

It's OK. 4.5ghz boost speed is disappointing, considering it's lower than the 5800X. I expected at least the same clock speeds.

It's purely to beat the 12900K and KS. Bit embarrassing for Intel if AMD's last gen platform can keep up with Alder Lake though.

My summary of November 2021 to 2022:
Alder Lake ahead until spring.
Zen3D 8 core released, roughly on par with the Alder Lake 12900 CPUs in most tasks. Ryzen 6000 series mobile APUs not far behind (ahead in graphics though).

Q4 2022, Raptor Lake and Zen 4 are released. Zen 4 steals the show...

So, Q2-Q4 not looking great for Intel, at least for CPUs.
