Rumors: AMD Zen 3 will gain around 8% IPC and 200 MHz higher clocks over Zen 2
AMD Zen 3 rumors: 8% IPC boost and higher clocks. An 8-core chiplet with 32 MB L3 cache is confirmed. Take it with a grain of salt.
If information from RedGamingTech author CrimsonRayne is to be believed, the next AMD Zen 3 architecture update will deliver an IPC gain of around 8% and clock speeds boosted by 200 MHz. This comparison was evidently made against the current Zen 2 architecture (Ryzen 3000).
The article suggests CrimsonRayne sourced this information from the Chinese forum ChipHell.com.
⤢ ВІДКРИТИA user named Zoo, who likely has access to an engineering sample of the processor, claims Zen 3 won't feature AVX512 extensions. That's a bit surprising, given Intel implemented these instruction extensions back in 2018.
Beyond the rumors, there's also some concrete information:
Following the recent Innovators Highlights Epyc conference in the UK, several key features of the Zen 3 microarchitecture have been confirmed.
⤢ ВІДКРИТИFor instance, while the chiplet remains 8-core, its L3 cache layout will see some changes. Instead of two 16MB blocks, there will be a single 32MB block, which should significantly improve cache latencies.
But back to the rumors.
Ryzen 4000 processor frequencies are also expected to see a boost. While current rumors suggest an increase of only 200 MHz, this figure could potentially grow to 300-400 MHz by Zen 3's release.
This is the only claim that doesn't inspire much confidence right now. After all, the vast majority of Ryzen 3000 processors can't even reach their manufacturer-advertised frequencies.
It's entirely possible TSMC will iron out its 7nm process, but that's just speculation. For instance, GlobalFoundries' 12nm didn't yield any significant gains for AMD. And the minor frequency bumps seen in Ryzen 2000 compared to Ryzen 1000 can likely be attributed to a new revision.
Overall, everything mentioned above should be taken with caution. There's still plenty of time until the Ryzen 4000 processors launch. Some information will be confirmed, while other claims won't. This was the case with previous leaks about SMT4 (4 threads per core in Zen 3), which never panned out.
