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.

1. non-pro users likely won't update their BIOS and will be more than happy with a really fast 8-core 9700X. They will also likely experience less issues with their CPU/memory/MB as a result (good for user and for manufacturers)
2. pro users will be very happy with the increased W and the power it gives.
Literally everyone is happy in such an arrangement.
If you want a Zen3 chip to perform, you need to keep it below 75c. And that´s not what I would call easy. With a NH-D15 on a 5600X I can barely do 4700Mhz in Cinebench R23. Looping pushes the temp over 75c at the the end of the second run and the clocks drop. The 5800X is even worse and known to hit 80c+ in normal games.
If used to kill time in a GPU bound title, sure, Its not like its impossible. But these things are not designed for the purpose of killing time. In fact, its quite the opposite.
As fevgatos pointed out, below, the top chips, mostly the most potent, and efficient silicon. These can be pushed beyond the point of reasonability, but they operate much more efficiently, due to lower tollerances, due to having dual full CCDs, with much higher requirements. Whereas, the 12, 8 and 6 cores being the the worst quality silicon, obviously. Also, the X3D, seems cannot have the trash dies either, do toExactly. Any CPU default/stock settings should be stability and effciency first. So that in case of some bugged firmware won't cause the savage situation, with default voltage going past 1.42V.
Everyone who want higher performance would just OC the chip, like it used to be for ages. Or just choose the power limit profile within UEFI/BIOS settings like 35W, 65W, 85W, 105W 125W... That would be really great, considering how the current AMD CPUs doing everyting auto.Where the intel i7/Ultra 7 is. AMD is copying intel's SKU naming scheme.This indeed looks like "netburst" deja vu.Exactly. Instead of doing "4080 12GB" all over again, they should have just made another separate SKU with higher power envelope, like they did before. Where 5700X used to be 65W, and 5800X being 105. This is fallacy. They already claimed, they are not up for pushing non X3D parts, as they would lose anyway, and now.... AMD has almost completely became intel, if not worse, and for much sooner.
The way to get these chips to perform is by using higher power limits. It helps for higher core boosts, and higher sustained clocks across a myriad of loads.
Old news here folks :)
Well at least they get there... sometimes, and if you want to run at efficiency then click 65W Eco mode if you're lazy or test in your apps and find your personal sweet spot for power-performance.
Nobody wants to read articles on how to fix thermal throttling, but articles with titles like "The one setting in the BIOS AMD doesn't want you to know about - 5-15% free performance gains with two clicks" could have been winners.
9700X should be at most 105W
9800X may be 120W.
Why not just add another 9800X? That's way more reasonable.
Also, you can't bake 96 MB of cache into the CPU die without doubling its size and significantly increasing manufacturing costs. Making a small CPU die and another small cache die is a lot cheaper.
For most people who are looking at this, the higher default limit is better. It's much easier to lower the limit than increase it with most motherboard.
I get you on the thermals, but AMD should have taken Zen5 to 3nm and stopped using the bolt-on cache, and simply added it to the die. It's time for AMD to stop playing money grabbers and just get this done. Then they can use this bolt-on x3D cache for an even higher-end range of server chips, which they can charge even more crazy prices for. Zen 6 better go down this route.
It's not a marketing trick. You either have high voltage and high clock speeds, or more cache. There's no other way around it.
Who said AMD can't keep up? Who said a few percent difference matters? Are we even talking about the same topic? :wtf:It doesn't matter what nm your chip is on. If you add +64 MB cache, you basically double its size, which results in much fewer chips per wafer, which increases your defect rate, and thus, the price of the end product significantly. Not to mention, in 2D, you have longer interconnects, which adds latency, you probably also need a larger socket, and so on. You can't just bolt as much cache to your CPU as you want.
