Well we don't have the official numbers yet, you are just using "leaks" as numbers. Not that long to go, just 3 weeks.Oh, really?
1800x -> 3700x +32%
3900x -> 5900x +19%
5900x -> 7900x +33%
7900x -> 9900x +14%
AMD has been doing that since at least as far back as Zen3.They are focusing on enterprise stuff, and nothing related to Zen 5 (yet)

Depends if its N4P then it should offer 11% performance increase over N5.no node advancement.
New AMD firmware for Zen5 released with performance optimizations.
I wonder how much that’ll improve performance. Hopefully some at least, but I don’t think it’ll make Zen5 reach the 40% IPC increase vs Zen4.
New AMD firmware brings performance optimizations for Ryzen 9000 CPUs
Gigabyte's AGESA 1.2.0.0a BIOS updates add performance optimizations for Ryzen 9000 processors.www.tomshardware.com
Detailed reviews show that at 88W it lose 12%, and in Cinebench R23 it lose even 15%, wich is certainly not below 10%.The detailed reviews show that 7900X needs like 170-180W for it's numbers, but loses below 10% even with 88W.
Your link has only one 7900X result in the test, so what are you talking about? In PCGH release test 88W 7900X is 8% slower than unlocked 7900X (which also only pulled like 180W).Detailed reviews show that at 88W it lose 12%, and in Cinebench R23 it lose even 15%, wich is certainly not below 10%.
They are porting the performance improvements from the Rocket Lake microcode and the power improvements from the Meteor Lake firmware.New AMD firmware for Zen5 released with performance optimizations.

PBO? Why not LN OC? )Bad math for your Zen 4 vs Zen 5 comparison. Its >17%. Also, its the only one out of them all that achieved all its gains with the combination of no clock uplift and no node advancement.
7900X PBO = 29.3K, 9900X PBO = 34.5K. Thats a difference of 17.7%, not 14%
Oh, wait... they stole my "bad math" ?In terms of scores, the chip was first evaluated at its default 120W mode and scored around 33,000 points in the Cinebench R23 multi-threaded test. For comparison, the AMD Ryzen 9 7900X scores around 29,000 points on average at the default operation at its 170W TDP. So you are seeing a 14% uplift

The 7900X score Wcfftech used has PBO, too.PBO? Why not LN OC? )
Anyway, if you haven't read the article (highlighted the key words for you, just in case)
To be honest, it seems like some people still have a vague idea of what PBO is (judging by the confusion in that artcle)We also don't know what PBO means for the 9900X in term of power consumption
One of them seems to be you, as you should be aware that PBO is either thermally or power limited, so in the case of using a insufficient cooling you will have no effect in moving from a stock to PBO setting.To be honest, it seems like some people still have a vague idea of what PBO is (judging by the confusion in that artcle)
Great, and you point is (other than showing that Tom is using a bad cooler)?
This chart was intended to illustrate the fact that the 7900X gains very little from enabling PBO in CB-type workloads, so the 14% MT uplift assumption still stands.Those charts mean nothing, what matter is the actual power, in Cinebench R23 the 7900X is at 175-180W.
Rapydmark score (probably unoptimized since it depends on a VC2017 runtime and possibly not using any SIMD) seems to suggest that software will need to be optimized for Zen 5 to unlock its potential. That's my thinking at the moment. The score? Not earth shattering so no point in revealing it or we'll get a WTFtech article saying Zen 5 disappoints!But I thought 32%, at least, was inevitable! Tier 1 OEMs don't lie and neither do Anandtech posters!
7900X3D is restricted by the additional VID limit for V-cache CCD, which is often reached before the thermal one.The 9900X will be at 162W at most since it s 120W TDP/162W PPT but i doubt it since the 7900X3D wich has also a 162W PPT doesnt exceed 120W in CB.
As long as we compare CPUs in cinebench nT this will always be the case, unless water cooling is used, which is kinda rare amongst the reviewers.One of them seems to be you, as you should be aware that PBO is either thermally or power limited, so in the case of using a insufficient cooling you will have no effect in moving from a stock to PBO setting.
See above.Great, and you point is (other than showing that Tom is using a bad cooler)?
