I agree that upgrading from Zen 4 to Zen 5 would make very little sense for a gamer.

However this fact was already well known and it has been discussed for some months.

It was not a surprise and verifying this fact is certainly a stupid justification for calling Zen 5 a flop.

Zen 5 does exactly what it has been announced that it will do. It provides a much greater energy efficiency than any previous x86 CPU.

It has a greater single-thread performance at a given clock frequency than any previous x86 CPU, but Arrow Lake S, which is expected in October or November, will have about the same IPC in the big cores, so about the same single-thread performance.

For any application that can use AVX-512 instructions, the desktop variant of Zen 5, i.e. Granite Ridge, can have a double throughput in comparison with any previous desktop CPU. For some people this will not matter at all, but for others this will be decisive.

The same happened at the previous SIMD throughput doublings that happened while keeping the same number of cores, e.g. Sandy Bridge after Nehalem or Haswell after Sandy Bridge.

For some people this did not matter, while for others it was a great improvement.

It's a flop for people who expect that after 20months, they'll get 13%-18% more. Perhaps Steve did not know this "already well known fact" and thus wrote about flop and Intel 11-th gen vibes.

How did you know before benchmarks were out? Did AMD say gaming performance will stagnate? (that would be very stupid thing for them to say).

In which applications is AVX-512 performance decisive? Video editing / 3D modelling?

There have been a lot of comments on many Internet forums, during the last months, based on various benchmarks of engineering samples, that the gaming performance of these new models will be only marginally better than of the existing Zen 4 models and some times even lower than of those with 3D cache.

Only when the models of Zen 5 with big 3D cache will be launched it is expected that they will be noticeably faster for gaming.

When a 5.5 GHz 9700X matches or exceeds in single thread performance a 6.0 GHz 14900K, that is an almost 10% over the older competition and it certainly is 13%-18% over the corresponding model of the same clock frequency from AMD's previous generation.

There are many professional applications where the AVX-512 performance is decisive. There would have been much more, had Intel not prevented this by their market segmentation policies, which force most software developers to support only the weakest and most obsolete CPUs. I am myself interested in certain CAD/EDA engineering applications, where I expect a good speed-up from a 9950X, at a much lower price than for any previous solutions. This is a nice change at a time when most computing solutions increase in price, instead of decreasing, like in the old days.

Still, the non-improvement in default setting surprised people, e.g. see the embarrasing confession by PCWorld, they did not believe the performance increase is so minuscule and asked AMD if that is for real.

More like 10%. And you have to overclock for that. Overclocking has become a fool's errand, you can expect it to cause problems, crashes, etc. Granted, if crashes are rare, gamers may go for it.

If you have unrealistic expectations, everything, everywhere is always going to be a flop.

You're not getting 18% more IPC at 30% energy savings in a single generation. That kind of uplift hasn't been seen probably since Pentium 3 vs Pentium 4 era, or maybe Nehalem vs Core Duo.

Regardless, if you run the Zen 5 CPUs at the same TDPs as the 7000 series, you can still easily get 15-20% uplift. It's just that AMD has chosen conservative defaults for energy efficiency.

And purely for gaming, you should be waiting for X3D versions.

Gamer/enthusiast segment expects performance increase, not energy savings. CPU consumption is not even the greatest power hog in gaming PC.

Zen 3 brought 20% more performance at much better power consumption than Zen 2, and this set expectations. Zen 4 was a weaker improvement, and some people hoped that was one time thing, and maybe Zen 5 will get back to Zen 3 level improvements or better. But the improvement is even worse this time.

That's why in this consumer segment, 9700X is like Intel 11gen, a token increase in performance (and sometimes, decrease) as compared to previous gen, and thus a meh product. In other segments, like in desktops for work, or laptops, focus is different, and the same performance at lower consumption is a great new feature. So it's not all bad - it's just meh for gamers and enthusiasts.

Yes, you can overclock, and expect to either win the lottery, or maybe get problems like Intel has. If AMD did not clock these higher by default, there is a good reason for that, and it is not because of green political reasons. AMD has every incentive to clock as high as possible, to look and sell better. Most probably, the current batches of 4nm chips out of TSMC aren't rock-solid at higher clocks.

Re X3D, yes those should be better. But this is marketed as 9700X, not as 9700, so it's a flop. PCWorld was so surprised by the non-improvement that they postponed their review and checked with AMD if their poor bench results really are what AMD intended them to see.

I buy my computers to use them, not to be "efficienr".

I dont' give a shit how much my laptop or desktop uses, but i need power when i use it.

Not every product is meant for you. I bet folk who cool their computers with HVAC and draw power by the MW do care about efficiency a lot.

Also, Zen 5 beats Intel in single thread performance while being efficient (by default). You could always change your bios to get even more perf using more power.
