Since early spring, colony collapse disorder, or CCD, a disease that causes honeybees to suddenly, mysteriously disappear from their hives, has made headlines around the world.

This showed up on my recommended feed, it is interesting that there is a possibility that the cache could be double stacked, probably unlikely tho....
What esle is interesting is that this is actually quite a different CPU to Zen 4.

I'm guessing increased clock speeds and improved 3D cache will bring the benefits personally and hopefully it'll be good
Not in need of it myself, esp gaming at 4k.
I think Zen 9000X3D will be the best gaming CPU for a long time, probably 2 years or more. Arrow Lake has very little chance of getting close to to the 9800X3D.
9800X3D & especially 9950X3D, with it's higher boost relative to the 7950X3D and further X3D optimisations will be the flagship, probably go down in history as being one of the GOAT CPU's.
Can't wait to order one
Just hope they don't rush it to try and spoil Arrow Lake launch - yet Intel release their next 320W CPU and spend your time perfecting BIOS, EXPO, XMP and stability so no issues to mar the launch.

There is another possibility that High Yield hasn't thought about.
AMD have shrunk the size of the cache on the chip by removing about 80% of the space taken up by the STVs, because the on chip cache was so large and the 3D stacked bit only had connectors on the underside, no STVs of its own that chip could be 64 MB for a total of 96 MB of cache.
With the on chip cache being smaller they might only put a 32 MB or 48 MB 3D cache on it.
I think the double stacking idea comes from an assumption, its rumoured to have 96 MB again and for that to happen this time it would need to be double stacked.
I would not be surprised if its only 64 MB this time, that's not necessarily a bad thing, too much cache can also be a problem, a lot of cache but not too much can be faster. The problem with too much cache is its slower to access.
Remember they reduced the Infinity cache going from RX 6000 to RX 7000 but its faster.

If it ever actually happens LGA1700 may have the last laugh out of these generations for thread heavy gaming if they do release a dual 6P Redwood Cove tiles CPU. (Basically what would have been Meteor Lake but with some tweaks).
Would be a bit of an odd move competing with Arrow Lake but still rumours it is happening.
To follow up on that someone has taken an educated guess at the layout of the CCD's...

Ryzen 9000X3D Series Cinebench R23 Performance Surfaces
Reports suggest that AMD’s upcoming Ryzen 9000X3D series may achieve Cinebench R23 scores that are 10% to 28% higher than those of the current 7000X3D models. According to leaks attributed to a source known as CodeCommando, the initial release will feature an 8-core variant incorporating the...

"Reports suggest that AMD’s upcoming Ryzen 9000X3D series may achieve Cinebench R23 scores that are 10% to 28% higher than those of the current 7000X3D models. "
"The 8-core Ryzen 9000X3D is reported to achieve approximately 2145 points in single-core and 23,315 points in multi-core performance.
..
Similarly, the Ryzen 7 9800X3D is anticipated to be 20% faster in single-core and 28% faster in multi-core performance than the Ryzen 7 7800X3D. These improvements suggest that the new X3D models not only enhance gaming performance but also maintain robust capabilities for multi-threaded applications."

If they’ve managed to solve the clock speed difference on X3D then for future generations or even the current 9000 series I really don’t see the point in releasing a regular X and X3D anymore unless the price difference is large enough.
Only point in them doing both now is because the X3D maybe much harder to manufacture quickly in large volumes.

So, X3D becomes the 'norm' aka the standard?
Where AMD goes others will follow, as in AMDX64 and 'chiplets' etc.

"Possibly" going to be announced at CES 2025 in January.
Sometime in Q1 2025 is all we know atm.
Intel announcing Arrowlake on the 10th October (this week), may or may not encourage AMD to talk some more on the dual CCD X3D SKU's.
AMD Ryzen 9 9950X3D and 9900X3D to Feature 3D V-cache on Both CCD Chiplets
Earlier this week, we got rumors that AMD is rushing in the Ryzen 7 9800X3D 8-core/16-thread "Zen 5" processor with 3D V-cache for a late-October debut. The 9800X3D succeeds the popular 7800X3D, and AMD probably hopes it will have a competitive gaming processor in time for Intel's Core Ultra...

AMD Ryzen 7 9800X3D Rumored to Get Faster Clock Speeds
Though it's a rumour and not one we like to cite, the AMD Ryzen 7 9800X3D is expected to offer significant improvements in clock speeds compared to the previous Ryzen 7 7800X3D.
This is looking very promising, looking forward to picking up one of these!
what are the main benefits of AM5 platform over and above AM4 other than longevity please ? I'm looking for an gaming rig upgrade 3060Ti plus Xeon quad core (!) . Complete mix of gaming including FS2020/FS2024- 60hz gaming.
only 4 options standing out:
prices below include a case, already have PSU and GPU
AM4 + 5700x3D + 64gb DDR4 - circa £500
AM5 + 7700x + 48gb DDR5 - circa 650
AM5 + 7900 + 48gb DDR5 - circa 680
AM5 + 7800x3D + 48gb DDR5 - circa 760
the only three that stand out really are the AM4, the AM5 + 7900 or the 7800x3D - but to me the AM4 option looks a lot better bet but no-one seems to recommend AM4 platform for new build
I haven't ever found I've upgraded a CPU once I've a built a PC (in the past)

Because it's no longer cost efficient
For example, just the other week I got for a build:
Ryzen 7500F (£103), 32gb ddr5 6000 (£58) with a Asus b650m-a (£80)
241 squids for an AM5 base
Also over the weekend there was a mis-price where a b650 board could be had for £55 delivered.
That would've put a new AM5 build at £216...that's incredible value.

Better support for M.2 drives (usually get more of them on a standard B650 or X670 board compared to B550 or X570).
Newer PCI-E tech (up to 5.0) and the secondary drives/slots usually stay 4.0 instead of 3.0.
Better CPU upgrade potential and a higher top-end performance for the socket, since it is very unlikely AM4 will get any new architecture CPUs.
Higher memory performance and higher capacity (192GB or 256GB, versus 128GB)
Integrated graphics as standard, which can be handy for backup or troubleshooting.
