AMD Ryzen 9 7900X3D 12-core Processor Drops to $389

[mkppo]

Tom's Hardware review of 7900X3D clearly shows which crowd could benefit using this CPU. It's no brainer CPU at this price, but not for everyone's needs. For example, it'd be perfect for me for media creation in Handbrake and in games I enjoy, one of which is Flight Simulator.

7900X3D is much faster in productivity than 7800X3D, while being equally efficient, and now far more affordable than 16-core SKU. In Flight Simulator, all three X3D CPUs are stellar, without any competition whatsoever.

That's the thing, in the odd instance where a 14900K/KS beats a 7xxx X3D, it's slim margins. In the games where the X3D is faster, it ranges from a narrow victory to outright demolition.

I built a 7900 X3D rig for a mate the other week who primarily games at 1080p. Managed to snag new one in Canada for around 370 USD. At that price, it was pretty much a no brainer

On paper, the Intel processors are substantially faster, but this doesn't necessarily translate to better performance in every single application. We all know why, so I won't be going into detail yet again, but the truth is no matter the choice you make, there's something that will fit your needs great. IMO, these are the absolute best use cases if you are focusing on something:

Strictly gaming = 7800X3D
Productivity focus = 7900X3D or i7-14700K
Mixed workloads = Core i9 or 7950X3D
Raw single-thread power = Core i9
Raw multi-thread power = Core i9

I refer to "Core i9" mostly because I'd lump all 13900K+ in the same weight class

I should've specified that I was speaking strictly about gaming. Productivity wise it's different.

Yeah, for just gaming the 7800X3D is all you need. Fits like a glove.

To be honest,
I think they should ditch the Async approach.
And just make the X3D CPU having 3D cache on both CCDs.
And tune the frequency to maximize power efficiency.

The Async problem is the main reason why I went for 7800X3D instead of 7950X3D

Zen 6 apparently finally fixes all these issues with the dual ccd. I will not get v-cache model until then. I don't just game, and X3D suffers too much in most (not all) productivity, but I do admire their efficiency. I'd get a 14700K or 7900X/7950X and power limit it to 125W-150W

Since that is your opinion, get one for yourself and leave us 7900X3D owners alone for preaching your opinion. I enjoy Computing on my 7900X3D. That includes Gaming.

No one brought you up, you're just being overly defensive again. Your feelings don't change the facts. I've been gaming on HEDT/workstation parts for years. They can play games. They don't get the best frame rates and that is fine. But there are better options. And the 7800X3D is simply better for this use case.

In your opinion. The 7800X3D is not faster in every single Game than the 7900X3D. I have been testing mine with 6000Mhz RAM and the results are interesting so far.

And the 7900X3D is better use for other case. Pick your priority. Heck I'd swap my 5800X for 7800X3D if it were just a drop in replacement even though I also do other stuff than game. Would still womp it in productivity, just not as much as say 7900X/X3D.

It's not my opinion. You're in full denial about how the architecture works and harping on about to defend your purchasing decision in a vain attempt to justify yourself, and you weren't even grilled on this. You have a bad case of FOMO, we've already told you, not being the best doesn't mean it's automatically bad. Not even the 7950X3D which doesn't share your chip's limitations with the 6 cores per CCD can keep up with the 7800X3D in gaming. And then again, the i9 can't either. It's literally not a problem.

How? A complete fix seems impossible as long as the CCD-IOD-CCD structure remains as is. An improvement, yes, that's probable and should be one of AMD's priority tasks.

Two routes to decreasing latency:
- new Infinity Fabric - much faster, facilitates smoother communication
- 16-core CCD - solves issues, as one V-cache die can work with up to 16 cores on one die

Pretty accurate though 14700K ST is as good as 13900K, but a bit worse MT than 13900K and 7950. The 7900X3D actually to me seems like one of the more practical options for gaming, productivity, and mixed workloads. The 14700K is pretty similar in that regard, but one leans a bit more heavily towards strictly gaming and the other mixed workloads, but the sweet spot on both is productivity focus.

Another possibility is an additional IF link that connects both CCDs directly.
