Question Zen 6 Speculation Thread

[Kryohi]

Zen 5's 139@5.7GHz translates into 174 if you give it +10% IPC in this application and 6.5GHz, which I think is already pushing realistic expectations as to what Zen 6 can deliver.

I don't think a +13-15% IPC improvement instead of 10% is unrealistic though, that's actually more likely than 6.5GHz fmax imho.

Zen5 is not 139 points @ 5.7ghz anyway (atleast not my systems)

that's what available online

Its close enough. I think my 9900X does 137 IIRC. Its not cracking 140 without some help.

Cinebench 2024:
M4 Max 177 1t
285K 145 1t
9950X 139 1t

Apple is currently 27% ahead in CB 2024 ST vs Zen 5. Gap will probably close quite a bit with Zen 6 vs M5, as Zen 6 will have full node advantage, but revert back to the ~25% or so advantage for M6 if that uses N2 or A16.

Well the cadence of Apple and AMD is quite a bit different, Apple is around 1 year cadence, at least with the base M and A chips, while AMD is on a 2-year or close to 2 year cadence. That's why I compare M6 with Zen 6, because of that cadence.

I prefer to compare laptop chips, though, it's where one gets the closest match with memory speeds and timings, with LPDDR comparisons, as DDR is just much faster in terms of timings and latency. M4 Pro vs Strix Halo for example.

I just tested on my system, first ran on v-cache CCD then on regular CCD @ 5.7ghz static

X3D Zen5 core @ 5.7ghz = 147 points in R24 ST


Vanilla Zen5 core @ 5.7ghz = 144 points in R24 ST

Looks like Zen6 will do more than fine. It just needs to clock above 6GHz

Thats not stock though. Stock chips dont hit 5.7 on the X3D die and dont even always pin max boost on vanilla die on heavy 1t loads. And you have wildly OC'ed memory, lol. The 139 is what you generally can expect with normal setup and EXPO 6000 CL30'ish memory. But I digress, its still just a 3.6% difference.
