AMD to Revise Specs of Ryzen 7 9700X to Increase TDP to 120W, to Beat 7800X3D
AMD's Ryzen 9000 "Granite Ridge" family of Socket AM5 desktop processors based on the "Zen 5" microarchitecture arrive in July, with four processor models in the lead—the 9950X 16-core, the 9900X 12-core, the 9700X 8-core, and the 9600X 6-core. AMD is building the CCDs (CPU core dies) of these processors on the slightly newer 4 nm foundry node, compared to the 5 nm node that the Ryzen 7000 series "Raphael" processors based on "Zen 4" are built on; and generally lowered the TDP values of all but the top 16-core part. The company is reportedly reconsidering these changes, particularly in wake of company statements that the 9000X series may not beat the 7000X3D series in gaming performance, which may have sullied the launch, particularly for gamers.
From the company's Computex 2024 announcement of the Ryzen 9000 series, the 9950X has the same 170 W TDP as its predecessor, the 7950X. The 9900X 12-core part, however, comes with a lower 120 W TDP compared to the 170 W of the 7900X. Things get interesting with the 8-core and 6-core parts. Both the 9700X 8-core, and the 9600X 6-core chips come with 65 W TDP. The 9700X succeeds the 7700X, which came with a 105 W TDP, while the 9600X succeeds the 7600X that enjoys the same 105 W TDP. The TDP and package power tracing (PPT) values of an AMD processor are known to affect CPU boost frequency residence, particularly in some of the higher core-count SKUs. Wccftech reports that AMD is planning to revise the specifications of at least the Ryzen 7 9700X.
Apparently, the Ryzen 7 9700X will undergo a set of changes to its specifications which see the TDP and PPT values increase. The TDP will be increased to 120 W, which is higher than even the 105 W that the 7700X comes with, and matches the 120 W of the 7800X3D. Given that the 9700X lacks 3D V-cache, the increased power limits should vastly improve the boost frequency residence of this chip. At this point we don't know if the re-spec includes an increase in clock speeds.
As to how AMD plans to go about this change in specs, given that a July launch would mean that chips with 65 W TDP may already have entered the supply chain; we honestly don't know, and the source article doesn't say. If we were to speculate, such an on-the-fly specs change could be deployed through motherboard BIOS updates that see the motherboard override the TDP and PPT values of the 9700X.
The idea behind the specs change, according to Wccftech, is to improve the gaming performance of the 9700X through clock speeds (boost residence) backed by increased power limits, so it gets closer to—or even beat—the Ryzen 7 7800X3D. A 9000X3D series (Zen 5 + 3D V-cache) is very much on the cards, but we don't expect those chips to come out before Q4 2024 at least.

There's probably a limit in terms of scaling for SRAM cells and access lines used in these caches. Regular, 2D, cache size has not increased much for years. Penryn had 6MB L2 at 45nm, Skylake had 6-8MB L3 at 14nm, and even current higher-end Intel and AMD non-X3D offerings have barely more than 30MB L3 accessible per core. Arguably Penryn was X3D of its day, above 50% of the chip area being that cache, but I think the point still stands.
You could argue that it's not mobile, but it really is.
If only they'd get X3D on mobile APUs. Though I suppose they would have, if they could.
I actually don't know, but I wouldn't bet on it. I mean, at which point does V-cache become pointless? Kind of important if you can't upgrade your laptop GPU anyway, integrated or not.
Edit: Or do you mean added cache shared with the IGP?
If you ask me, I see no initiative and reason to buy anything from this generation - simply the stagnation is too pronounced, and the core count deficit is too strong.
AMD definitely needs a move innovative approach, if they don't want to lose market share to intel.

This or DOA.
You can lower your power limit to suit your cooling, or you can buy a bigger cooler. Or you can leave it as it is and accept that it might run into Tjmax occasionally. It's a matter of choice.
A shared cache - maybe an L4 - on the IOD or whatever equivalent shared with the IGP could be a fun idea, though I wonder how much good that would actually do.
The reason I'm asking is that the universal recommendation of throwing a 7800X3D at anything doesn't always seem worthwile.The memory bus width is doubled and RAM speed is much higher for Strix point, I guess that'll have to do for now. Also, It will benefit in many benchmarks.
I started PC gaming with a NUC5i7: 384 cores and no L4 cache (Iris 6100). Later I upgraded to a NUC7i7: 384 cores and 64MB L4 cache (Iris Plus 650). 49% faster in Time Spy GFX, 73% faster in Fire Strike GFX. Similar improvements noticed in all games. The GPU cores had not changed substantially when you compare scores from other parts with the same # of cores and cache and the system memory went from 1866 to 2133 MHz in the 2 models, so not a huge difference.
Shared L4 for iGPU gaming could be a huge help.

le:the 1,two,three-4 by a hypothetical stretch core boosting sure is similar.
As I have been saying since Zen 4 - AMD needs to stop this 3D cache grab, and incorporate the extra L3 directly in to the die.
This situation has only happened because of this greed.
AMD has outdone AMD at it's own stupid game. Intel is going to give them a bloody nose, and they don't have a product that competes for another 6 months, and then the cost of those parts will become an issue.
Zen 6 needs to bring an end to this greedy farce, or this will just happen again.
