Zen 3D V-Cache Ryzen CPUs May be Available in December 2021

[pcuser]

Well, the "next" Threadripper is coming in November, apparently. I'd like to think it's getting the 3D chiplets because it's going to be a real slap in the face if it doesn't. Considering it was originally rumoured for August, it's possible those stacked chiplet yields are going great guns and there's enough to populate Ryzen and Threadripper SKUs, so release was held off a couple months.

Delay could be due to many reasons but I like the idea of AMD having a top notch product. That may keep the prices more reasonable.

ah Shizzle... didn't realise it's a 25% performance leap. Just bought my second 5950x FACEPALM fml

it's not confirmed. All we have seen was Lisa Su introducing a 12 core prototype that had an average 15% performance boost in games.

It's also not untill Jan anyway from an article I saw on the subject recently.

The issue we have as tech enthusiasts is waiting.

From now untill Jan is still quite a while away.

It's not like any of the 5000 series are bad CPUs or slow so if you have a NEED then I think it's not warranted to wait.

If it was 2 months away then I'd say wait.

Sure Alder Lake will drop prices. But then it depends on need.

Wonder when the leaked benches will hit October use think..

 

[subbytna]

Looks like prices are just falling into line with the rest of the world. Most likely because we are no longer in lockdown and U.K. supply is meeting demand.

I'm seeing 5800X now £30 cheaper elsewhere than ocuk

 

[rumple9]

I've seen 5800x in a couple of places for £300 today so prices are dropping

 

[Freddie1980]

I've seen one place selling the 5950X for £530 which only £30 more then what OCUK are selling the 5900X at. I wonder how he's able to sell it so cheap? Smuggled in bulk from China? VAT scam?

Probably just making less profit

Its probably fictional. Like your £160 5600X claims.

You shouldn’t take yourself too seriously

 

[Cyber-Mav]

Just shop around deals are always to be had.

So the question is, how much L3 3D cache can AMD stack on a CPU right now?

why I'm glad you asked

the answer is 768mb!

I want to imagine a future where the CPU has 20gb cache and the PC doesn't even need RAM anymore

 

[LePhuronn]

Presumably that 768MiB includes the 32MiB already included in each chiplet since the lump o cache stacked onto a chiplet is 64MiB. So to be super accurate, AMD can stack a maximum of 512MiB into their CPU designs.

That's a metric f-ton of cache and only 1 stacked layer to achieve it.

You're basically talking about a SOC... Good if you like to throw away your device instead of upgrading.

lolwhut?

 

[Zarax]

lolwhut?

A CPU like what you describe is basically a system on a chip, which means everything soldered together... Like your phone or Apple M1.

 

[LePhuronn]

Grim's theoretical RAMless system hardly constitutes a disposable SoC.

Right 768MB of L3 Cache.

I'm looking at my 5800X and thinking 32MB, that's quite a lot for an 8 core CPU, Intel are only putting half that on the 11900K.

Along comes Zen 3D and slams a gigantic 768MB L3 willy on the table!

I remember looking at Intel’s super high end (£10k plus per CPU!) 4/8 core Xeon line up with 60mb of cache and thinking that’s a lot of cache to work with.

A few years later and AMD have beat Intel by a factor of 12!

Oh and the small difference of 16x the cores and for less money.

Its going to be very interesting to see what Zen 3 can do with that much cache to blow Ops out in to.

The CPU tech war is definitely back on with AMD once again making all the innovations that matter. Sorry if that comes off as fanboi'ish but its true and not for the first time.
