AMD Lists Ryzen 7 9850X3D CPU with 5.6 GHz Boost Frequency
AMD has launched an official website placeholder for the Ryzen 7 9850X3D processor, which was leaked in October. As a part of the "Granite Ridge" Ryzen 9000 X3D series, AMD is reportedly developing two additional updates to the lineup. One is a flagship model, the Ryzen 9 9950X3D2, and the other is a refined eight-core, 16-thread X3D design. Today, AMD's website confirms the Ryzen 7 9850X3D, featuring 8 cores and 16 threads, 96 MB of L3 cache, and a boost clock up to 5.6 GHz, with a 120 W power envelope. This represents a 400 MHz increase over the Ryzen 7 9800X3D model, which has the same cache and core configuration. AMD is likely using higher-binned dies it has saved over the past few months to offer a better alternative to Intel's upcoming "Arrow Lake Refresh," scheduled for early 2026, and "Nova Lake," scheduled for late 2026.
However, details about the new flagship model, the Ryzen 9 9950X3D2, featuring 16 cores and 32 threads, remain uncertain. This chip reportedly includes 3D V-Cache on both chiplets, totaling approximately 192 MB of L3 cache. It is said to operate at a base frequency of 4.30 GHz, with a boost up to around 5.6 GHz, and has a TDP of about 200 W. The 9950X3D2, with its new naming convention, suggests a tradeoff of slightly lower peak boost speeds (-100 MHz) compared to the single-stack X3D Ryzen 9 9950X3D model, but offers significantly increased cache capacity. Today only the higher-clocked Ryzen 7 9850X3D is confirmed by AMD, so we might have to wait on the dual-chiplet X3D2 SKU a bit more.

4 DIMM slot boards suck ass on AM5, whether you are using 2 DIMMS or 4.
Looking for non-scalped RAM? Check your local STAPLES. 32GB kits around $110. In store only.
That is all.
It can be easier to setup an X3D system since cooling and RAM isn't as influential, which is a big perk for e-sports players who just want to buy it and game.
But then again the Raptor Lake setups tend to be cheaper, which is a perk for e-sports players who aren't pros.

This came to mind for some reason:
sizeMHz, but how you use it" argument? :DI'll sneak in a couple more:
I think those who have not upgraded already are at this point waiting for upgrades to the I/O and for the RAM prices to drop.
What AMD is doing is no different than what Intel does with a refresh or "KS" version of a CPU.
Newer manufacturing runs likely means AMD could get higher clocks, but why am I not surprised by reactions like this.
When in game which most people will be using these cpu's for the difference isn't that great.
I really wish they could do a system that uses less than 100W at peak and less than 10W in idle, but as long as they are competing for the absolute best performance, they have no choice but to push the power envelope.
Not everything is about money.My 7950X3D uses exactly 100 W at peak with a disabled boost (at constant 4.2 GHz). :D
Can you provide the cost per kWh
Heat out put on a 9800X3D isn't that high. When playing BF6 i'm doing 57-61C and 100 watts on cpu package.
You are not going to feel a difference in temps in a room with a 7800X3D vs 9800X3D.
CPU Cooler - be quiet! DARK ROCK 5
I will not be convinced an X3D chip can/will run hot when in my hands with air or AIO :)
It does sip power though..
I'm pushing for RDNA 5 but we won't see that until 2027. So if the 12 cores Zen 6 X3D chips drops before the GPU i'm grabbing it on launch.
From a Cinebench 2024 run
- It boosted to 5.2GHz on all cores
- VID remained around 1.1V
- Power consumption via the PPT value was ~100W throughout
- Temperature averaged around 62C but I was using the motherboard's fan curve which is more aggressive than the one I usually use via Fan Control. Cooler is a Thermalright Phantom Spirit
- Final score was 1330
- I also ran it with turbo disabled via the OS. It went down to 4.6GHz, VID around 0.985V to 1.0V, and 70W PPT, with a final score around 1200
In most of the games I play, though I have a global FPS cap of 125FPS, the CPU uses around 40W. The only CPU heavy game I regularly play, FFXIV, can bring it up to 55-60W, but otherwise it'll go down to around 35-40W. If I disable turbo, it usually shaves off 5-10W.Another thing of note is the turbo behavior on the 9800X3D (and possibly Zen 5) is different than the 7800X3D. The 9800X3D boosts to max clock regardless of core/thread occupation. The 7800X3D only boosts to max clock for a CPU core if it has both threads occupied.

I do have an 7800X3D, but I don't know if it's actually working. I guess I could make that a holiday project to test it.
