    AMD CPUs in 2022: Zen 4 in Second Half, Ryzen 7 5800X3D with V-Cache by Spring
    érdekes kérdések az AT-es cikkbem:

    """
    Why only Ryzen 7, not Ryzen 5/Ryzen 9? Because this is a new project for AMD, they want to find out how a processor like this will be welcomed into the market. A lot of users (myself included) expected AMD to go all-in with a big 16-core version, however anything Ryzen 9 requires two chiplets, and adding the extra V-Cache does require an extra cost in silicon and packaging. During a semiconductor shortage, I was told that this is the best way to get it into the hands of many people while also not in the super high-cost bracket. It also means one single unified 96 MB of L3 cache, without having to deal with two chiplets worth which might not be optimized immediately. Future versions of V-Cache on next-generation products may be expanded to other Ryzen members of the family.

    The frequencies are lower than the regular 5800X? The cache does add a few watts to the power both in terms of idle and load. Rather than bin a stricter chiplet, the decision was made to reduce the frequency a little, but still allow overclocking. The chip, while listed at 105 W, still has the 142 W package power tracking for motherboards that support it.

    Who is this chip for? The focus is on users playing video games over anything else. The extra cache is meant to help with communications with discrete graphics cards, offering additional performance above the regular R7 5800X. Productivity workloads are less likely to be affected, and for those users the regular Ryzen CPUs are expected to be better. The Ryzen 7 5800X3D is designed to be the ‘World’s Fastest Gaming Processor’ (when compared to the 5900X and 12900K).

    In terms of those performance metrics, AMD is quoting:
    - From 1.0x to 1.4x at 1080p High vs Ryzen 9 5900X + RTX3080 (15% average)
    - From 0.98x to 1.2x at 1080p High vs Core i9-12900K (DDR5) + RTX3080
