The 7000X3D processors based on Zen-4 have double the L2 Cache per core so on the CCD that has the V-cache that has a larger L3 cache and thus a longer L3 cache lookup latency compared to the Non V-Cache 7000 CCD so the extra L2 will help. So for any Ryzen 7000X3D CCD with the V-Cache that doubled L2 cache will hide more of the L3 V-Cache lookup latency compered to Ryzen 5000X3D generation that had half the L2.
The Problem with the 5800X3D was productivity workloads that where non L3 Cache capacity sensitive but where CPU clock speed sensitive so some productivity workloads like higher clocks more than they liked any extra L3 cache capacity. There even where a smaller segment of workloads that liked the smaller L3 Cache more than the larger L3 cache because they where L3 Cache Lookup latency sensitive so the smaller L3 cache on the Non V-Cache Ryzen 5000 variants had better performance there with lower L3 lookup latency, even at the same clock rates. But AMD with Ryzen 7000 and Zen-4 has doubled the L2 Cache to hide more L3 Cache latency so even with the Larger L3/V-Cache SKUs the extra L3 Cache Lookup latency can be somewhat ameliorated by a larger L2.
Chipandcheese does extensive Micro-Benchmarking tests and the articles on Ryzen 5000X3D are worth a read there as they do all the sorts of Micro-Benchmarks that stress the Cache Levels for Latency testing on different sorts of productivity and non productivity related workloads But the Large L3 cache sizes come with tradeoffs but compared to DRAM Latency any cache level has many times less latency and many times more bandwidth than any DRAM so for Gaming workloads the more cache(L3/Other Cache levels) the better there.
TSMC Chose Arizona because of all the existing trained Fab Worker Pool, Intel has had fabs in Arziona for ages, and Arziona has the presence of all the companies the service the Chip Fab Industry and are already in the Phoenix metro area! So the Chemical suppliers and the EUV/DUV Machine suppliers and all the other Chip Fab suppliers have a presence in Arizona. There were also the incentives and the available land at low costs there and if one looks at the Satellite Images for the TSMC Arizona location there’s a pretty large reservoir there near the TSMC fab location in Arizona. So for Phoenix that also includes the educational resources that are geared up for training and educating the workforce for Chip production, as Intel’s had large chip fabs there for decades as have others. TSMC recycles most of its water even in Taiwan where they have had water shortages as well but not as bad as Arizona. But really for solar power and the electrical grid(Hoover Dam/other) there as well that’s pretty stable in that region of Arziona, California, and Navada.
