100usd cheaper but generally much faster, seems it was worth the wait if you hadnt done a cpu upgrade yet.

If you're using the price on their for the 5950x keep in mind that is the launch MSRP. Real pricing on the 5950x hasn't been anywhere near that high for quite some time now. All Zen 3 have regularly seen large discounts since July/August as well.
Absolutely impressive CPU, amd know what their doing. They are designed to run at 90+ celcius, however Apple M1 does that too, even with cooling.

This is just my quick initial impressions from parsing a few reviews from a gaming stand point in general for the line -
1) There's a general diminishing returns issue in terms of benchmark CPUs in terms of gaming performance.
2) There's also the issue of maybe re-examining what to actually benchmark on a CPU test vs a GPU test.
3) From a value stand point if you are on AM4 either stay with what you have to upgrade to 5600-5800x3D.
4) From a value stand point with a new build either Zen 3 or Alder Lake (there is some regional/spot variation in pricing between the two) or wait for Raptor Lake (albeit we'll see once more information get's announced, but judging by some preliminary information it's not going to be a value consideration either). There's only a few specific scenarios in which current <$200 CPUs might actually be functionally weaker in practice and not just academically weaker, and those CPUs have much cheaper overall platform costs as well.
5) In terms of top end performance it's basically a mixed situation against 5800X3D and even high end Alder Lake builds to some extent. Becomes more of a specific usage and setup scenario currently.
6) If the top end is your consideration probably waiting for X3D versions of Zen 4 (some speculation announced at CES) would be the way to go. In theory, barring some surprises, it should be likely end up the clear winner (with maybe some specific losses to Raptor Lake). Of course pricing/demand might be concern in that scenario as well.

The CPU was designed to run at 95C and doesn't throttle at that speed. Architecturally it is more efficient as it is faster at every TDP, and crushes the competition at 65W. It's just that AMD decided to sacrifice power efficiency for peak performance when boosting. See Anandtech's Cinebench run at 65W:

Its indeed a very impressive chip imo, its beating Alder Lake at a much lower TDP and a healthy 30% increase over Zen3. Moores law's dead they say.

When the competition starts this kind of "competition" you need to adapt somewhat, unfortunately. In any case, Computerbase measured only a 5% performance loss by using the same power limit of the 5950X and, as the power limit is selectable, it comes down mostly to the user preferences,The CPU was designed to run at 95C and doesn't throttle at that speed.

Huh? MSRP's are the same or cheaper than Zen 3. That's awesome. If only Nvidia had followed suit.
Thought I'd do a quick breakdown of the Spec scores from Anandtech, hopefully I haven't made any errors. Total % comparison with 1T and MT comparisons broken down by each test. Tl;dr, rounded %:
7950X vs 12900k totals average = +14% int and +10% fp 1T, +48% int and +26% fp MT
7950X vs 5950X totals average = +23% int and +29% fp 1T, +40% int and 41% fp MT
7950X vs 12900k totals average = +14% int and +10% fp 1T, +48% int and +26% fp MT
7950X vs 5950X totals average = +23% int and +29% fp 1T, +40% int and 41% fp MT

Here in germany the 5600X costs 180€. That will be nearly 200€ less than the 7600X. Zen3 prices crushed hard after Alder Lake.
In the same vein Zen4 CPU's prices will also drop hard when Zen5 is around the corner.
