AMD Ryzen 7 9800X3D Comes with 120W TDP, 5.20 GHz Boost, All Specs Leaked

Specifications of the upcoming AMD Ryzen 7 9800X3D processor were leaked to the web by a Geizhals listing. The chip comes with a processor base frequency of 4.70 GHz, and a maximum boost frequency of 5.20 GHz. The base frequency of 4.70 GHz is a significant increase from the 4.20 GHz of the current 7800X3D, while the maximum boost frequency has moved up a couple of notches from the 5.05 GHz of the 7800X3D. The TDP of the processor is set at 120 W, same as the 7800X3D, and higher than the 105 W revised-spec cTDP of the non-X3D Ryzen 7 9700X.

The specs sheet also confirms that the 3D V-cache size is unchanged generationally. The stacked 3D V-cache die adds 64 MB to the on-die 32 MB L3 cache, which is exposed to software as a 96 MB contiguously addressable L3 cache. The per-core L2 cache size remains 1 MB per core. The biggest contributor to generational gaming performance increases will rest on the increase in frequencies, the new "Zen 5" microarchitecture and any IPC improvements on offer, plus L3 cache performance improvements AMD introduced with "Zen 5." We recently reported a spectacular theory that AMD has designed the 9800X3D such that the stacked 3D V-cache is positioned below the 8-core CPU complex die chiplet, and not above it, which should significantly improve thermals, and clock speeds.

Chrispy_For whatever reason, that scaling doesn't seem to change much even at much lower performance tiers.
PCIe 4.0 x8 or PCIe 3.0 x16 is close to optimal, but performance starts to drop of measurably if you slap an 8-lane card like a 6650XT into a PCIe 3.0 motherboard.
What? Do you really consider a 2.2% performance reduction worth mentioning? I doubt anyone here does.

freeagentPeople say the 5700X3D is a great deal.. but it is half a GHz slower than the 5800X3D
400 MHz isn't worth the 100 dollars difference in my region.

I'd have to ask someone who knows better, but my guess is, aside from the transfer of graphic assets to the GPU, there's not *that much* data moving through the PCIE lanes. So you can get away with less lanes or lower PCIE speed without any significant performance loss.

My 7800x3d is able to run all core at 5.0 ghz on cinebench with a simple overclock - another 200 mhz isn't exciting at all. :sleep:

Seems about normal, the better ones are up around 5300 by the looks of it.

9800X3D will be faster than 7800X3D for sure both with ipc and mhz.

dgianstefaniThe main perk is if you can overclock since the cache is now under the cores. Being able to lock all cores to 5.4 would make me buy one.
Now that is something I can get behind. I would love to see some overclocking on this series of chips. Would make me get one in a heartbeat!

I had not heard about the cache being under the cores so that is pretty cool!

So, at this point, 9000 series is a skip.

Let's wait until AMD decides to use TSMCs 3nm, for a change.

Depends on your needs and your current equipment. You're on a 7000 series tho, so it makes sense to just skip and wait for whatever comes in a year or two, one or two generations in the future.

Hopefully I'll keep my motherboard.

I'm sitting on a 3600 so, I might do an AM5 build and get a 9000 series processor for myself (X3D or not, it will be a good jump). My mom's desktop PC could use a replacement so moving her from the aging i3-4330 to my current 3600 would be a massive improvement for her.

They were pretty easy to get for $300-320 for a while people should have jump on them. I got 4 around that price for builds.

That's the route I took coming from 5950x but only because I found a once in a blue moon special on Amazon for new 7950x that would have made ebay shoppers furious.

I predicted uplift could be quite noticeable, ~15% in gaming and around ~10% in productivity task.
Seems too optimistic but I had no choice after selling my 7800X3D at profit :D

I think some people have their head in the sand (or old silicone!) I have yet to see one Zen4 or 7000 cpu show higher single threaded performance than an I9 14900k, Zen 5 9000 does. There are tweaks to the memory performance too, with lower latency and higher bandwith.

Broken ProcessorWhat I'm interested in is can you lock all cores like normal Ryzen chips I've zero interest in pbo.
What do you mean? If you can manually set core multiplier to certain value? Of course, this will be available. PBO is optional and can be disabled in BIOS.

Is there one proper re-test of Zen 4 or Zen 5 with all the fixes for Windows 11? Everything that really unlocks the potential?

I don't expect it to be much better than 7800X3D via games, but the innate IPC gains are welcomed.

Guru3d benched around 8-9% benefit for 9000 over 7000 clock for clock (Cinebench). CPUZ bench reflects sort of the same story.

Should be a more snappy CPU over predecessor, while offering better objective performance in pretty much everything else.

I wonder if they're EOL.

Remember what happened before the 9000 launch.

AMD did nothing with the 7000's.
AMD launched the 9000's.
No one/few saw the 9000's worthwhile and bought 7000's instead.

AMD learned a lesson and cut/stopped 7000X3D production in time for the 9800X3D launch. Possibly using that production capacity for the latter anyway.
In the meanwhile, the 7000X3D prices goes up due to lack of supply. All three models, even the 12 core which have no successor for months is currently at $600.
Now some people interpret this as the 9800X3D costing $600. :laugh:

9000 can be put in 7000's motherboard, so no problem.

KlemcIt will become 10% less over 7800x3d when Win update will introduce a bug that auto-enables/forces RECALL !!!

It's now an NPU right ?
MS has actually enabled that stupid feature on non-NPU systems as well in 24H2, as this was enabled automatically at some point on my 7950X3D :banghead:

It can be disabled through PowerShell, thankfully. Even if it doesn't work, I still don't want that crap switched on.

IIRC those results use ReBAR and PCIe 3.0 motherboards (eg B350, X370, Some B450 and X470) typically don't have it, which worsens the gap.

I said measurable, I have a feeling it's around 6-7% without ReBAR but it's not really enough to worry about, just something to understand is happening.

Even Windows 10 22H2 did that on my system (no NPU here, either). I can't wait to finish the new Alan Wake 2 DLC so I can wipe my system completely and switch to Linux. Microsoft has gone too far this time.

Looks like EU ISO doesn't have it like windwhirl said in Win11 thread, as a French ISO user i didn't have it listed in ADK app/x i deinstalled btw, looks true.

That aside, I heard on Reddit that EU users are not getting Recall (due to GDPR), but I can't confirm that myself.

freeagentPeople say the 5700X3D is a great deal.. but it is half a GHz slower than the 5800X3D, which is half a GHz slower than 7800X3D, and you cant overclock any of them, and by that I mean go above stock power limits, and use boost override.

This one should be good.. if not, I am waiting for Zen 6 lol :D
The 5800X3D is unobtainable now and even before stocks dried up it was commanding a $320 price.
The 5700X3D has frequently sold for under $190 and is only $209 right now, which is a massive 40% price cut for not even a 10% performance drop.

If you're not buying a 4090 and instead have a more modest GPU like a 7700XT or a 4070 then spending more than double on a 7800X3D platform isn't going to net you any improvement at all.

He's not the best benchmarker but J2C just basically leaked this murders everything in gaming in a cudimm video he published.

DavenI doubt that 7800X3D users will see much of a difference but 5800X3D users should see a good increase and non 3D users on AM4 might see GPU generational increases in frame rates.
Good increase if using Rtx4090 and 1080p
freeagentSeems about normal, the better ones are up around 5300 by the looks of it.

9800X3D will be faster than 7800X3D for sure both with ipc and mhz.
Faster in games? using 4090? sure
how about using slower GPU and maybe 1440p resolution?
1-3% difference maybe?

Sure sure, just go and buy 4090 and u maybe get +10% even 15% if gaming 1080p..

Or try 720p, difference can be even higher then, +25%?

Thanks, at least one see the facts

I like tuning CPUs.

And tuning X3D is boring AF.

Now it wont be, hopefully.

If you like to run your CPU at stock, all the power to you.
