Highly anticipated: AMD's Ryzen 7 9800X3D is now official and will arrive to become the successor to the lauded 7800X3D from a year and a half ago, and the first X3D CPU to be fully unlocked and primed for overclocking. The new CPU arrives on November 7 priced at $479, which is roughly $30 more than the 7800X3D debuted at. Is it worth it? Be sure to check back on launch day for our full review.

AMD's latest is built on the Zen 5 architecture and utilizes the company's second-generation 3D V-Cache technology. The chipmaker said it relocated the cache memory below the processor, putting the core complex die (CCD) in closer proximity to the cooling solution.

By keeping the cores cooler, AMD was able to ramp up factory clock speeds. The chip features eight high-performance cores / 16 processing threads with a base clock of 4.7 GHz and a max boost clock of 5.2 GHz. For comparison, the 7800X3D was clocked at 4.2 GHz and could boost up to 5.0 GHz.

AMD further noted the chip carries a "hearty" 120W TDP and 104 MB of total cache.

The new X3D chip provides up to an average eight percent gaming performance improvement over the previous generation model, and is said to be 20 percent faster than the competition (an Intel Core Ultra 9 285K).

In titles like Far Cry 6, Hogwarts Legacy, and Ashes of the Singularity, gamers can expect over a 20 percent increase in performance compared to the 7800X3D according to AMD. Versus the new Arrow Lake chip, AMD claims its 9800X3D is more than 50 percent faster in games like Watch Dog Legions and Cyberpunk 2077.

While the new chip is fully unlocked and ready for overclocking, you'll still be taking a risk doing so. In the fine print, AMD notes that operating the chip outside of its published specifications will void any applicable product warranty – even if done so using AMD hardware or software.

Clearly the rumours about them turning the packaging of the 3d vcache and the dies upside down must be true if they've opened up the overclocking, maybe they've finally got the trans silicon vias (TSVs) to the point where they have enough signal integrity and can handle the frequencies they need, good work
 
Raised the price of 7800X3D recently, back to $450, which makes Me believe 9800X3D will be 'meh' at best. At least Steve Walton won't be able to say that It's performance per $ is weak.
Unless One bought 7800X3D when It cost $300.

They didn't raise the price, supply is running low as they haven't made any new ones for over a year now.
 
I said it would be 465, and it's 479, not too far off xD. Since this X3D can be OCed, let's wait for in depth reviews. I'm still eager to upgrade my rig to AM5, just deciding between 7800x3d or 9800x3d
 
I'll be interested to see what overclocking means on modern chips like this. Don't they already come stock with boost speeds they can't sustain for long or on more than a core or two? And don't they already automatically push themselves to their thermal limits?

You're right, the news here is that the thermal/voltage headroom means the X3D chip no longer comes with a lower stock clock compared to the equivalent X3D-less chip. It means little to overclocking because the overclocking headroom on Zen chips compared to just using boost/PBO is close to none.

Weeeell, You got Me.
But, They haven't made 5800x3d for some time now, and It just disappeared from sales, like month ago. Last pieces went for under $200, but started in 2022 at the same $450.
So I don't know what to think. I smell price gouging.
;-)
 
Only if AMD had a 5090 killer to pair with the 9800X3D, it would have been sweeter. Lisa loves giving Nvidia free advertisement!

The 5800X3D had several things going on with it. The biggest was that AM4 was already well saturated with highend AM4 parts and AM5 was right around the corner when it came out in April 2022. The 5800X3D came out VERY late in the life cycle of AM4 and even the 5000 series so very few people were going to swap out there 5800/5900/5950X for a 5800X3D. It was also a new concept for people so people really didn't know what to expect from it. The 7800X3D already had plenty of development time from X3D parts for people to correctly assume that it was going to be the gaming champ of the 7000 series. So people with high end AM4 machines just waited for AM5 and the 7800X3D top upgrade. The 5800X3D was a godsend for people looking to save money who had older AM3 and AM4 boards. The other side to that is AMD had tons of unpackaged Zen3 dies sitting around. AMD was sticking 3Dcache on old dies simply to move old product and that's how we got the 5600X3D. AMD was still making X3D AM4 chips well after they stopped making zen3 dies.

Now the X3D chips have matured with consumers actually expecting them and planning future builds around their release. That said, the non X3D ryzen chips are still great chips, it's not like X3D is necessisary for a quality gaming build, you just wont get le-uber-elite gaming points. Realistically, you won't notice the difference between a 7800X and a 7800X3D unless you have a 4090 and play games on low to get 300 FPS instead of 200FPS. That said, the X3D chips are definitely a "nice to have" part if you plan on holding onto the chip well past it's intend life cycle If you are the type of person who upgrades every other generation or every 2 generations, I don't really see a point in them. There are people with pairing 5800X3Ds with 4090s and having a great experience.

AM5 MIGHT end with zen 6, but that's really speculation. However, I'm probably going to put a 16 core zen6 X3D chip in my next main build and replace all the AM3/AM4 stuff in homelab with ebay AM5 crap when AM5 reaches EOL
 
Probably real world games will be less , who here games at 1080p ? not many if any
Apparently it competes well in day to day with productivity stuff, so a real good allrounder ( waiting reviews )

Can this extra memory be put to use elsewhere ?? or is it too niche
 
This thing will be the best gaming chip till Zen 6 3D hits.

20% improved ST and 30% improved MT / application performance over 7800X3D. Massive uplift. It is very clear that AMD don't have to hold back clockspeed anymore. 2nd gen 3D cache looks great.

Up to 26% improved gaming experience. When you remove the GPU bound games from their slide, it's a 16% overall gaming uplift instead of 8%.

And with OC unlocked, this thing will be the nobrainer chip for high fps gamers for a looong time. With tweaking and OC, you could be looking at a 25-30% uplift in CPU bound gaming and a 35-40% uplift in applications.

9900X3D and 9950X3D won't beat it in gaming overall due to inter CCD latency, even if AMD puts 3D cache on both CCDs they will loose overall. Minimum fps is what suffers the most with dual CCD chips.

Getting 9900X3D and 9950X3D only makes sense if you actually need more than 8C/16T for other stuff than gaming.

Watch this if in doubt:
He clearly states that gamers should choose single CCD and even with Proces Lasso, 7950X3D is still loosing to 7800X3D in gaming. Benchmarks are in the video for proof. 7950X3D is not even close and has way worse minimum fps than 7800X3D in all the games tested.

You have to 100% disable the non-3D CCD on 7950X3D to get it on 7800X3D level, which makes little sense. 7800X3D is vastly cheaper, uses less power and requires only a cheap air cooler.

7800X3D is still a great gaming chip, but 9800X3D delivers on all aspects and fixes the lacking application performance.

People that buy top tier gaming CPUs like this, generally are high fps gamers, sitting at 240 Hz minimum, meaning they are CPU bound in most cases and GPU is far less important.

5090 is a 4K/UHD maxed out solution and CPU performance don't matter much here.

Building a system for high fps gaming is vastly different than building a system for high res maxed out gaming. You spend more on CPU (and maybe memory) here, and less on GPU.

Let's wait for independent review results to confirm how much faster this 9800X3D will be. AMD don't have a good track record of late when marketing performance improvement between generations.

Neither has Intel or Nvidia.

There is already tons of leaked benchmarks out and 9800X3D is 20% faster in ST and 30% faster in MT - Cinebench, Blender etc.

AMD included Black Myth Wukong, which is a close to 100% GPU bound game, so fair play to them.

Remember they are relatives xD Also on the contrary, if you want to max out your 5090, you need a 9800x3d, not a 285k xD
 
I think it’d be cool if AM4 got a one last hurrah: a “5850X3D” which also had the cache mounted underneath the CCD…

What makes this possible now is that Cache and CCD are produced in the same process node.
 
Afaict, anyone considering doing AI on a desktop may profit from a 3d cache cpu.???
 
Please, the 9900X3D can't compete with the Intel Ultra 9 285k....in AI

I actually do own 7950X3D and I am beating 7800X3D gaming performance. New bios updates allow per CCD Precision adjustment for core so with -21 on 1st ccd and -15 on second ccd. Also, even after disabling 1 CCD, the 1st CCD on 7950X3D has max clock of 5250 MHZ vs 5050 with 7800X3D. Most folks don't pare it with low latency ram. I have my GSKILL ram at 6200MHZ 28-37-37-28 with secondary and tertiary timing at low numbers. My gaming performance is higher with CCD on with nearly all games. Especially, CPU heavy games such as Cyberpunk 2077 and Star Wars Jedi Survivor etc. The milage may vary with games and desktop builds even windows version has an influence.
 
People still overclock? I haven't overclocked since the "pencil trick." A few Mhz extra better not be the reason for higher performance. You can keep your 5-10% if that means loads more power and temp. If there is no clear performance gain from the architecture alone, this is a fail. I really hope the only reason for AMD to move the cache to the bottom is not just so they can clock it higher. We're back to what Intel was just doing by adding power to get gains.

For people who are building from scratch, 9950x3d and 9800x3d will make sense but if you have an even 5700x3d, then this will be a momumental waste of money to upgrade. 5700x3d is $180 and you can stay on AMD4 and not have to upgrade an entire PC.
