AMD Rushing in Ryzen 7 9800X3D, Expect Product Launch Late-October

You'll never know which one is better unless you build systems with both.

I agree, there is no substitute for actually owning the hardware reviews are just a small snippet taking from a small portion of the game just to give a general idea of how they compare someone's actual use case at home could differ quite a bit making one a much better option than the other even though they may appear a couple % different in reviews.


For applications it's usually more black and white though.

My 5800X build is 4 years old... 9800X3D or 265K. What will it be boys?

If only you get the 5800X3D instead

 

[SL2]

IMO, the considerable price gaps/aggressive price cuts may explain the sale.

That doesn't explain the 9000 barely making it to top 25.

 

[Sykobee]

My only guess, or more like a wish, for 9900X3D and 9950X3D is 1 x 16 core Zen5C chiplet with even more V-cache as a compensation.

I don't know anything about the cons of using a 5C chiplet, besides having half of L3.

I think they will stick TWO V-cache dies on top of one or both CPU chiplets.

However Intel has been pushing the small core count on their chips, so your idea has merit.

8C Zen5 with 128MB dual-layer V-Cache
16C Zen5C (no V-Cache)

48 Threads.

Or the above, but switch the V-Cache around to the Z5C chiplet, so the Z5 can run full speed.

AMD clearly does not have good marketing practice. They should be releasing their best SKU first. What a disaster.

Maybe they need a Z series for Desktop (to match handheld Z1 Extreme, etc).

Instead of a Ryzen 7 9800X3D call it Ryzen Z 9800 or similar. RyZen.
RAIZen, get some AI in the branding :/

AMD Rushing in Ryzen 7 9800X3D, Expect Product Launch Late-October​

Did someone actually say `"Rushing", or is it just clickbait?

Several posts says "Oh no, AMD shouldn't rush things", and rightfully so, yet when I look I find no info about it being rushed?

I think they will stick TWO V-cache dies on top of one or both CPU chiplets.

Two? I think we would be talking about diminishing returns there.

More cores under the same roof/CCD/chiplet with V-cache would be great, even if highly unlikely. Yes, I called it a wish in the first post..

 

[GoldenX]

Instead of rushing a new CPU why don't they rush the Windows and BIOS patches to make their CPUs run fast and properly?

Why would anyone care to update their PC if its clear and present that some windows patches can boost the cpu half the way of a new platform?

Trying to rush Microsoft is a fool's errand.

 

[Wirko]

I think they will stick TWO V-cache dies on top of one or both CPU chiplets.

Why not, haha. TSMC did state that their hybrid bonding (copper to copper bonding) tech could be used to stack more than two chips.

And here's my speculation: the V-cache chip contains additional L2 too, not only L3.

 

[redzo]

I think that they they've actually listened when they launched zen 5. A lot of the press blamed them for following intel and setting the power too high on zen 4. They've listened and gave us lower power parts. But what went wrong is that zen 5 isn't that much faster compared to zen 4.
I think and hope it is time for those dual die - dual cache parts.

 

[kondamin]

will take some wind out of intel's sails but it won't boost sales

 

[Makaveli]

If only you get the 5800X3D instead

late on that boat production has stopped on them and they are getting hard to find unless you go to Ebay and get fleeced.

The sooner AMD releases it, the sooner we can start the requisite 6+ months wait timer for the post-launch kinks to be ironed out. I'm only half kidding. At this point I wouldn't buy a new CPU on launch day, or even in the launch month, from either AMD or Intel.

 

[Visible Noise]

Considering how AMD launches have been going recently, the last thing they should be doing is another rushed launch.

AMD seems unable to learn from their mistakes.

 

[evernessince]

I'm pretty sure dual V-cache chiplets have been debunked by AMD, it's not worthwhile.

Not debunked, AMD just stated that the returns were diminishing.

That was with prior gen though, we don't know how this new architecture interacts with the 3D cache or what benefits 2nd gen 3D cache will bring.

Even if we assume that 2nd gen 3D cache brings the same performance uplift, AMD might decide to use multiple cache chiplets simply because Intel is a threat. It's really the same reason AMD hasn't upped core counts at each tier, because Intel hasn't provided them enough reason to need to yet. At the end of the day competition drives the market.

 

[wolf]

So, after reports of delay to 2025, no they are rushing it? Intel's new CPUs must be impressive if AMD got spooked.

My money is on trying to salvage the reputation of 9000 since the bungled launch of the first models.

 

[ir_cow]

So a 7800X3D with a higher cost

 

[z1n0x]

Finally someone with a decent explanation. Do you know the limit for them? I've seen 5.1 GHz in HX 370.

That's the frequency of "Classic" Zen5 core. The frequency of the "Compact" Zen5c core is 3.3 GHz.

Now you lost me again lol. We're talking 3D CPU models here, which actually has a lot of cache. With current 3D models having 12 MB L3/core, and 5C having 2 MB/core, you'd have to add V-cache.

You can't add V-Cache to the "Compact" core, because as @dgianstefani pointed out, the "Compact" core lacks the TSV (Through-Silicon Vias). TSV are the connections that join the V-cache to the base core die.
If you're thinking of adding another level of V-Cache on the "Classic" core. Then you (well, the engineers) have to consider a lot of factors. Complexity, cost, heat density, diminishing returns.
You can't just add more of something and expect it to work better. Processor design is about the balance between the difference aspects of the architecture, hence the name Zen.

Excited to see what features the dual CCD 3D chips bring. My luck, I'll buy the 9800X3D and the dual CCDs 3D chips will out perform a single CCD 3D chip in games, lol

 

[Wirko]

If you're thinking of adding another level of V-Cache on the "Classic" core. Then you (well, the engineers) have to consider a lot of factors. Complexity, cost, heat density, diminishing returns.

If this ever becomes reality, it will be in some variant of Epyc, for some very specific tasks, where the returns are not diminishing (and license costs are per core).

Tell me one hardware launch which has been 100% perfect according to "PCMR" expectations

I'm only half kidding. At this point I wouldn't buy a new CPU on launch day, or even in the launch month, from either AMD or Intel.

Right and part of the reason is that the client side of things is so much more vast & different/varied than 10 or even 5 years back! You can have people running PS3 emulation, running Cinebech 24*7 or doing BOINC, geekbench et al. The software today is also a lot more complex & there's a ton of security issues as well. This isn't such a big deal with servers per se where you run everything in a controlled environment!

 

[phanbuey]

No, because the reason they removed the TSVs is to save space, it's no longer a compact core if it has all that stuff.

TSVs have negligible impact on die size... they saved space by primarily removing the cache. Which is why it would make sense to have 3d cache layer on top.

 

[LabRat 891]

New IoD for 9000 x3d? Or firmware level changes; like, games being isolated to 1 CCD?

I think the bigger hope from most is that the latency to dram is what's holding back Zen5 compared to Zen4 and that the cache will alleviate that issue at least for gaming.

Any radical changes will have to wait for Zen6.

 

[Minus Infinity]

AMD's is on a roll, maybe they'll launch it with two 4 core ccd's and v-cache on just one ccd to shoot themselves in the face again.

I want the AMD Ryzen 9 9950X3D, but how long will I wait? What is the first of the year? mmmmm

Probably announced at CES.

I am sorry. Do you have valid data/evidence to back up your claim?

Do your own research. Plenty of tech sites have stories about this and the sales data being reported from multiple retailers.

 

[Taraquin]

I would be surprised if it performs better than 5% above 7800X3D on avg. Still a good move from AMD launching the "winner" early on, especially when fighting Arrow lake which I presume will be a good launch.

 

[cerulliber]

Those guys in the AMD testing labs are probably working their asses off.

No,they are not. Zen5 launch proove that. They launched beta-testing, unfinished products with beta-bioses and nearly zero ipc on gaming. I have zero trust in amd corporation after their gaming presentation in zen5 and I will wait for independant and fair reviews before upgrade decision. I refuse to be a beta tester or buy mvp products on my money. This isn’t case for early adopters with no budget limits and just buy it attitude.
