*** AMD "Zen 4" thread (inc AM5/APU discussion) ***

It's impossible to have a 35% mt increase while keep the same amount of cores, which I assume they will. I'll be surprised if we see anything above 25% increase between the 5600x and the 7600x.

I'm just going off what AMD have told us but yeah I'd be surprised if AMD hit +35% MT especially if we're only getting 8% IPC, for AMD to achieve 35% on a 7600X it would need an all core clock in heavy workloads in the range of 5.4-5.5ghz which would definetly blow out the 65w TDP limit.
 
It depends on the exact model/cenario/benchmark they have used. With an 8% IPC increase it would require a 25% increase is clock speeds to get +35% multithread throughput.

If they mean base clocks then that would only require around 4.5GHz base clock for zen 4, which seems easily achievable given they seems to be upping clocks with the new gen and process.
Realistic all core boost for 5000 series without thermal and power constraints was already in the mid 4GHz range, requiring speeds of 5.5+ GHz to reach 35%.

My guess is they are talking 12/16 core models within TDP limits.

It gets muddier if they use a benchmark where their IPC increase is actually higher than the averaged 8%, requiring less clock speed uplift.
Or if the benchmark used was particularly good at using power/heating up the 5000 chip and which the new process mitigates substantially allowing improved boosts clocks for that workload.

That's not what they said, the said the 16 core would be 35% faster, given the 5950X only clocks to about 4Ghz all core high load its not difficult to get the 7950X to +35% if its clocking to 5Ghz, that alone is +25%

The 5800X already clocks to about 4.6 to 4.7Ghz in a high stress loads. 5Ghz would be +9%

If that's the case then when you add that together with the ipc the 13600k should have around a 20% MT lead over the 7800X and a huge 50% lead over over the 7600X.

Do you think AMD will revert back to Zen 2 pricing on these SKUs as not only as performance will be lacking in MT but also if prices are way cheaper then it encourages people to opt for the AM5 which will guarantee future sales.

They will have to price their CPU's competitively. :) If they are too expensive people wont buy them, they will buy their competitors.

Doesn't matter, people will still buy amd cause "upgradability". They will change 3 cpus and by the time we get to the 9600x in 2026 it will perform equal / better than the 13600k from 2022. After all, who wants to spend money on motherboards, right? :P

I have a feeling AMD has designed these Zen 4 chips to be cheap and is using clocks for the majority of the gains, offer cheap lower performing Zen 4 CPUs to entice loads of people on AM5 then the big guns will come out with Zen 5 offering huge gains with a hefty price tag similar to how cheap Zen 2 chips baited people onto AM4 then Zen 3 cleaned up with the big margins.

You might be right.
