Despite only two weeks until release, the rumor mill continues, and it appears the AMD 9800X3D has yet more tricks to reveal. The AMD 9800X3D has been widely talked about over the last couple of months while rumors for the 9000X3D series continue to pile up this particular processor continues to have more spec leaks leading up to its release. The Rzyen 7 processor featuring Zen 5 technology is set to arrive on November 7 and while official pricing has yet to be announced, just about every other detail has seemingly been leaked.

3D V-Cache is now underneath?

First up is a rumor regarding the package design for the 9800X3D. In what could arguably be a facepalm moment for some it is rumored that AMD has re-engineered the 9800X3D by reversing the layering of the CCD and 3D V-Cache (aka L3D). By placing the CCD back on top, and directly under the heat spreader, it once again becomes easier to cool the CCD and opens the possibility for another rumor that has just surfaced. This rumor regarding the redesign comes via HXL, who has been nearly spot on in leaking many details regarding both the 9000 series and the 9800X3D in particular.

Possible Full Specs Leaked

Next up are the potential full specifications for the AMD Ryzen 7 9800X3D. These come via overseas pricing aggregator Geizhals and while these do appear to be legitimate, we won’t truly know until the CPU is officially released. One very important thing to note, as it could relate to the above rumor regarding the CCD being on top of the L3 cache now, is that at one point the online pricing aggregator was spotted (via VideoCardz) as listing processor with having an unlocked multiplier which would allow for overclocking. This is something that has not been available for X3D processors thus far. However, a recent check of Geizhals website shows that detail is now removed.

The other detail that seems odd is the pricing which originally put it at ~$267 and then dropped to ~$258, something that seems nearly impossible given the launch prices for the 5800X3D and 7800X3D, and recent rumors have also suggested that consumers should prepare for an increase and not a nearly half-off discount. In fact, while this story was being put together an overseas etailer has just listed it at ~$448-$558 (with or without VAT after the current rate conversions).

While an unlocked multiplier does remain a possibility there are some other interesting specs to look at. A 120W TDP with max thermal of 95°C seems reasonable as does recommended DDR5-5600 memory, and then support for 24 PCIe lanes. Motherboard support including A620 through X870E seems a given as well. An RDNA 2 iGPU feature 2 CU/128 SP clocked at 2.20 GHz is interesting for those who might not pair this with a dGPU, although that is hard to imagine given what the processor is designed for. Regardless, enthusiasm for the launch of the next-gen 8c/16t part is strong among the PC community who eagerly await its launch, as well as the 9900X3D and 9950X3D processors.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
