Current whispers suggest the 9850x3d with one cache for both CCDs could be a solid choice... I'll keep an eye on how it performs in games compared to the older models, but it seems the 9800x3d might edge out in this case. What do you think?
It seems the 9950X3D may include two 3D CCDs, which could be facilitated by the new cache layout beneath the CPU. We'll keep monitoring the situation.
My consideration is that even with two caches, the 9850x3d (or 9950x3d) should perform better, possibly reaching temperatures near 9950x. The present 9950x temperatures aren't very comfortable based on what I observe. The 9800x3d might already be sufficient for most tasks.
Ok, wtf is a 9850x3D? It is a 9950X3D. Early rumors suggested that the 9950X3D would come with 3D V-Cache on both the CCDs, but now I think it's confirmed that only one CCD is getting the 3D V-Cache die. I do want to state that what a lot of people get wrong that about this is that they are disappointed. You shouldn't really be. It doesn't make a lot of sense to put 3D V-Cache on both the CCDs. In gaming, you already want to only have one CCD active for that game. If you have 3D V-Cache on both the CCDs, you will still run into the massive latency issue, and I think that it will be worse if one CCD has to gather data from the other CCD's 3D V-Cache, but I am not sure if that is how it works. A lot of people blame the weird problem with the 7950X3D to be the 3D V-Cache being only on one CCD. Even if both of them had the 3D V-Cache, you would still only want to have one CCD active. So basically, all your background stuff would be running on your other non 3D V-Cache CCD. They won't benefit much with 3D V-Cache. And when it comes to multi-threaded workload, it could probably be better to not have 3D V-Cache (except some workloads which prefer faster memory than clocks, like AI/ML, but aren't you using GPUs for them?) which could probably make them turbo higher. This was a much bigger problem on the 7950X3D, as with its heterogeneous design, the turbo behavior was different of both the CCDs in that the 3D V-Cache CCD would generally turbo lower than the one without it. This was because the 3D V-Cache die was constructed upon the CCD, which meant that a lot of the heat from the CCD would be trapped inside, and so the cooling the chip would be harder. That is why there were so delicate with voltage and overclocking was disabled. But now in Zen 5, the 3D V-Cache die is constructed on the bottom of the CCD, which means cooling the CCD is much easier and so overclocking is unlocked now. But still because of lesser complexity without the 3D V-Cache, the non 3D V-Cache die might be able to turbo more or overclock more. All this, with the really high price increase by putting 3D V-Cache on both the CCDs, means their margins would be even lower.
nobody really thinks about idle temperatures. just switch off the fans and keep it quiet in the 80s. actually, no one cares much about component temperatures—what matters is the power output.
They might benefit from sharing a single, larger 3D V-cache between both CCDs. This way, regardless of which thread is active, they're utilizing the same cache, similar to a shared network drive. Many games actually run on more than eight cores, spreading the workload across several, which prevents overheating specific cores.
It seems you're curious about the 9850X3D. Could you clarify what you'd like to know? Are you asking about its purpose, features, or something else?
