PC Building

[joumxyzptlk]

Currently running Rzyen 5950x (on ASRock x470 Taichi, 64 GB ECC RAM). The workloads I have make use of the 16 cores. The workloads would run faster with 3D Cache, but not this way.

I was hoping for the 7950X3D to have cache on both CCDs, and got disappointed. Now AMD disappoints me a second time. For the 7950X3D the explanation "thermal reason" seemed valid, but that cannot be the reason this time.

I will delay my PC upgrade again. Planned was: 9950X3D (with extra cache on BOTH CCDs) with 96 GB ECC RAM or 128 GB ECC RAM. But what for? Why not deliver the CPU the community is longing for? Why not listen to customers?

I feel mocked. My next computer will be AMD again, not only 'cause of real ECC RAM capabilities in consumer CPUs, but until then probably a new socket since the current will have reached its three or four generation limit and DDR6 will be there until then.

This "post new message" Form has a bug, the "PC Processors" list is EMPTY in Firefox: I cannot select the right "PC Processors" community, so it has to be in "Red PC Building", which is the closest. (Another disappointment, like Windows 11 24h2)

I used to be a component engineer back in the mid-1980's, working with vendors that were producing the highest quality semiconductor parts (S-level for space applications).  Thermal constraints have been an ongoing headache for the industry, even with process sizes getting smaller and smaller.  Todays processors were a pipe dream to the system engineers that were designing with 4-bit processors back then.  And here you are unhappy with the performance of the 7950X3D processor.  

Perhaps you need a workstation (Threadripper CPU?) that could better handle your workloads.

I think AMD already tested a 16core X3D and even though we are all curious, of course, if its not out yet its because its not viable. Either the chip itself or to be honest, the market.

The 9800X3D already has its way paved for dominance. Especially being capable of overclocking at insane levels where 7800X3D wouldn't even budge.

The thermal shouldn't be the issue as the 9800X3D is unlocked now.

Conclusion. 2 CCD with X3D will come, just not right now.

Also, getting a X3D CPU and use slow ECC memory doesnt add up. For true workloads the regular 7950X 170watt beast will just be plain better than the 7950X3D. Even older Threadrippers will still Kick the X3D model.

Just my 2cents

Some light about a full X3D

I can believe that.  Who wants to pay perhaps $1K for a CPU if it's intended for the consumer market?

It would be rather silly to spend so much on a CPU when most workloads don't benefit from the 3D v-cache the way gaming does. My understanding has been that the 3D v-cache hinders performance in most workloads outside specific loads that are designed to use that extra cache.

Did you ever consider the EPYC line of CPU's.  One of the features of the EPYC series is 3D cache.
