AMD Zen 4 Reportedly Features a 29% IPC Boost Over Zen 3
While AMD has only released a few Zen 3 processors which are still extremely hard to purchase for RRP we are already receiving leaks on their successors. Zen 3 Milan processors will likely be the final generation of AM4 processors before the switch to AM5. AMD appears to be preparing a bridging series of processors based on the Zen 3+ architecture before the release of Zen 4. Zen 3+ is expected to be AMD's first AM5 CPU design and should bring small IPC gains similar to the improvements from Zen to Zen+ in the range of 4% - 7%. The Zen 3+ processors will be manufactured on TSMC's refined N7 node with a potential announcement sometime later in 2021.
Zen 4 is expected to launch the next year in 2022 and will bring significant improvements potentially up to 40% over Zen 3 after clock boosts according to ChipsandChesse. A Zen 4 Genoa engineering sample reportedly performed 29% faster than an existing Zen 3 CPUs at the same clock speeds and core counts. The Zen 4 architecture will be manufactured on a 5 nm node and could potentially bring another core count increase. This would be one of the largest generational improvements for AMD since the launch of Ryzen if true. Take all this information with a heavy dose of skepticism as with any rumor.

I have 2 first gen Ryzens and one 3rd gen.
Hope to add a 4th gen CPU soon!
LOVE YOU AMD!
On that note ...
If the rumour claims ZEN3+ is on the mysterious Socket AM5, that rumour is incorrect.3-5% was an Intel problem.
Not AMD :DNot all Games and Programs will gain you equal Performance. Some perform better than others.
:roll:Its an addiction for some it seems :D
Not 2.9%. Right? Or is my vision blurry
:eek:
New Process + new chiplets + new IO chip + new chip(sets) + new socket + new RAM standard + new PCIe standard, all in one generation? Now THAT doesn't make sense to me.
I'm not really longing for that.
How about keeping ZEN 3 anything onto AM4 and start fresh with ZEN4 AM5.
Like what they've done down below mixing up the naming schemes. They should keep ZEN2 away from Ryzen 5000 series, that belongs to Ryzen 4000. This mixing up only causes confusion. And consumers don't know what they are buying. If I seen a Ryzen 7 5700U I would automatically assume its based on the newer ZEN 3 Micro-Architecture. Any consumer that finds out its actually based on ZEN2 will most likely return it, as they should for the dishonesty.
This move comes from the Book of Intel. lol
Ryzen 7 5800U ZEN3 Cezanne
Ryzen 7 5700U ZEN2 Lucienne
Etc.,
Let me explain: Zen 4 is supposed to be on TSMC 5nm, which is a hot item right now (and will continue to be so for quite some time) and there are bigger fish after it, which means that they will only be able to secure a significant amount of wafers after at least some of those other ones (especially Apple) will (partly) move to 3nm and that would likely mean 2H 2021 at best for the launch. Now they could probably do it sooner, but with laughable stocks just like Zen 3 and they can't afford another fiasco like that (or at least they shouldn't, but then again, this is AMD after all... :D ). So, what do you do? You release a mid-generation on an "old" node with a new socket which should also help to reduce the amount of bugs that come with all new stuff (just like one poster above already mentioned); we know there are enough of them as it is already!
Oh and regarding the near 30% IPC uplift? God knows they'll need it against Alder Lake, especially after coming in (probably) 6 months late to the party!
6 months sounds too long tho, I'd guess 3 - 4 months.
That's what AMD has done since ZEN.
ZEN to ZEN+ Respectful IPC uplift
ZEN+ to ZEN 2 Significant IPC uplift
ZEN 2 to ZEN 3 Significant IPC uplift.
ZEN 3 to ZEN 4 Significant IPC uplift.
Had AMD not done this, ZEN would have died a horrible death already.
ZEN 4 is also a new design, heavily overhauled according to Dr. Lisa Su. That's the only way to gain such incredible IPC gains per release.
We've witnessed it from ZEN to ZEN2 and from ZEN2 to ZEN3. Absolutely no reason to think ZEN4 won't follow this pattern in IPC gains.
That is Skylake the last 6 years which is now topped out and hence Rocket lake. Eventually Zen will get there and AMD will need a new arch.
No more are the days of the past where CPU generations would gain you 1-5% if you are lucky in IPC gains. AMD solves this issue by architectural improvements for each ZEN generational design. That isn't volatility lol, that is Technological Advancements. A perfect example is Intel's Skylake, AMD did everything to avoid such fate, Skylake offered up to 1-5% IPC gains per gen, which is miserable at best.
Intel, at the time, only needed to respond to Ryzen's new 8-core processors with a 6-core processor, though. But through the years following AMD's introduction of Ryzen, AMD has been pushing hard to improve its processors each year, and Intel had to take notice and match their pace as well.
That's how we moved: desktop processor performance has, due to AMD's resurgence, become an intensely competitive field.
