AMD to unveil Zen 4 CPUs at CES 2022

Well all-core was claimed to be at least 5GHz from the demo AMD already showed. Single core is usually significantly higher, but who knows? Maybe AMD have some tricks up their sleeve to surprise us with tomorrow.It just says 15% single threaded uplift, we have to assume that is over Ryzen 5000.
And there it isthe thing is Ryzen 5000 already boosts to around 5Ghz ST, how much higher should we expect it to boost? most of that 15% will come from IPC, it does seem a little low but if the slide is real that's it.
Depends on the workload, if it boosts all core in hard workloads like Cinebench that in impressive, especially for the 16 core one as they actually only run between 4Ghz and 4.2Ghz in R23, the 5800X around 4.6Ghz to 4.7Ghz.
In games they can boost all cores to around 4.6Ghz to 5Ghz depending on the SKU.
If the IPC gain is 12% and they boost to 5Ghz all core in R23 the MT score can be as much as 37% higher for the 7950X, so from 28,500 to 39,000.
Did you factor in the increased clocks? While we don't know the final clocks for the 7950x we've seen 7800x models leaked at 5.2ghz so definitely boosting higher than 5950x
So 7950x may have 200-400mhz higher single core clocks than 5950x in addition to its 15% IPC
But 15% isn't IPC, it's IPC+ clocks lol. IPC is below 10%
Single thread performance = IPC+Clocks
Zen4 has 15% more single thread performance over Zen3 thanks to higher clocks (+5ghz boost) and mysterious IPC gain ( 8-9%??)
New details, keep em coming leakers!
* The 600-series motherboards will offer up to 24 PCIe Gen5 lanes for storage and graphics
* Up to 14 SuperSpeed USB 20 Gbps (TypeC)
* WiFI-E6 support with DBS/Bluetooth Low Energy 5.2
* 600-series motherboards will be equipped with HDMI 2.1 and DisplayPort 2 outputs
* AM5 platform also supports a new technology called SmartAccess Storage. This technology adds GPU decompression for Microsoft DirectStorage Enabled Games.

Thats not what the slide says or the article, it says it has at least 15% ie worse case scenario + we have little context to teh slide, lets just wait till tomorrow
Why? if you look at retailers that publish sales comparisons its obvious that AMD are still outselling Intel in retail CPU's, and by significant margins.
To release a CPU that is better than the one currently outselling Intel in retail is not going to do that any harm is it?
Sales numbers? Is this about performance (in our computers) or popularity? (Just buy what all the cool kids buy)

The problem is that they are competing with Raptor Lake not Alder Lake.They are comparing it to Zen3, you can see it by looking at the L2 cache size. So if 7950X has 15% faster single core vs 5950X it will be at best on par with stock i5-12600K

Hope they are not gonna fall behind and be similar to early Zen days and have weaker ST and higher latency vs the competition.
Anyway, best to wait for actual numbers for a better idea.
He was commenting on it being enough to counter Intel, or not.
