Hope AMD could integrate ten cores into one CCD chip.
Hope AMD could integrate ten cores into one CCD chip.
It's a single chip unit. The operations in the present IOD are distributed across the "platform IO" and the memory paths shown. That's not what I meant. Whispered talks suggest Zen 6 will include such core counts. Which CCDs will end up in your Ryzen processors remains unclear. High-density cores operate at slower speeds and have significantly less cache (because cache consumes a lot of space). I doubt designers are planning dense cores with TSVs to add extra cache above them, as it doesn't make sense to boost cache for tasks those cores aren't intended for. I don’t think anyone is worried; I genuinely believe they’re indifferent. You probably underestimate the requirements. Personally, I have no interest in 3D-cache (since I rarely play games) and ignore cross-CCD complications. I’d prefer more cores regardless of whether they’re split into three or one big one. I’d choose the cheaper option—performance won’t differ much. A notable downside is slower clocks. For non-gaming tasks, lower speeds mean reduced efficiency, so you’d pay more for a chip that actually lags in everyday use. The 7900x3D and 7950x3D exist mainly as specialized models with minimal market success, making sense only for serious gamers who need those extra cores.
I'm familiar with the monolithic die discussions others have shared. It makes perfect sense with a typical Mono layout. I'd also agree that it doesn't matter if the extra cores are on a different CCD. The main goal for adding more cores to a single CCD is to prevent core parking complications. If the 7900X-3D and 7950X-3D had identical 3D V-Cache CPUs functioning like regular 7950X, there wouldn't be any interest in additional cores since gamers who multitask or edit video would simply opt for the 7900X-3D with 12 cores. Yet, this isn't the case. One CCD uses 3D V-Cache while another has standard cache and higher speeds, requiring core parking and scheduling to assign tasks properly. This process introduces delays and makes Windows Scheduler less effective. Consequently, the 7800X-3D often outperforms the 7950X-3D in gaming despite its higher frequency—because core parking and scheduling remain problematic. Having multiple CPUs would be ideal if they were all identical and had no parking issues, but 3D V-Cache units can't achieve that. Many AMD users have expressed interest in a single CCD version with 10 or 12 cores and no core parking. That would provide the fastest gaming CPU along with sufficient cores for strong multi-core performance. If you know of a high-core-count CPU with 3D V-Cache that avoids core parking, I'd be eager to purchase it right away. Others would likely agree. Unfortunately, currently, true 3D V-Cache CPUs without issues are limited to 8 cores. Your mention of Zen 6 promising more cores is interesting, but without a concrete number, it's hard to judge. If you believe future desktop CPUs will offer 10 or 12 cores on a single CCD due to rising overall core counts, that would be exciting. However, if only 'Dense Edition' models with reduced cache and speed will see higher core numbers, I doubt many will be interested. My focus remains on Ryzen-based systems—standard desktop CPUs—not high-end servers or workstations like Threadripper or EPYC. What we really need is a single CCD with 3D V-Cache plus 10 or 12 cores, or a multi-CCD setup with identical 3D V-Cache units and no core parking or scheduling hassles.
I understand your desire, but have you noticed how in this thread no one else voiced the same need as you did? Yep, that's what I believe will happen. I personally would actually love a CPU with 1 regular 8 core CCD (and no v-cache), and another CCD with only dense cores. A 24c/48t CPU this way would be amazing. As I don't really play games nor use windows, I don't really care about the whole core parking drama Who is "we"? As I said above, you're the only one in this thread demanding such thing. Most other people are fine with a 7800x3D, and those who also have work to do either have a second PC with higher core counts, or just accept the drawbacks of the hybrid CCD models.
