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.

They already do. And Intel's 7nm is delayed yet again.

How have we moved from "3-5% and you should be happy" every year, to the "if it offers less than 15% we are going to be disappointing"?

Weird, that Zen3+ will be AM5 socket.
I'm waiting for 5900XT as a 5900X with improved clocks, but immediatelly appliable in current motherboards. This idea is now destroyed.

Great!
Let's talk lower priced Zen3 products...

hopefully AM5 CPU bracket is backward compatible with AM4 so that AM4 CPU cooler would work with AM5

I wanted to upgrade my CPU/Mobo/RAM but I wonder if I shouldn't just wait a little longer, the new socket will probably give more available upgrade paths further on in the future and wasn't it supposed to use PCIe 5.0 / DDR5 memory too?

After all, Zen4 will be out in 2022.
Not this year.

"Leaked rumours" also suggest 29% better availability... I don't put much trust in those...

I decided to wait with the upgrade. In any case, if I won't be able to get a ZEN4 due to supply issues, I will definitely buy a Zen3 hoping the supply issues will be resolved back then. Maybe price will drop a bit who knows.

How? Competition...

Any CPU line up with actual stock/availability blows everything out of the water. Even if it is 14nm.

So AMD should worry about that first.

No more milking cunsumers for less than 10% increases in performance as Intel did. AMD is on a roll with more huge gains.

How this gonna fare in today boomers benchmark?
Like maxon cineprice and futuremark 3dstock?
Cus single thread, multi thread, boost clock and gaming are so millennials.

What happened is people realized Intel was sitting on their ass, and AMD stopped eating crayons. Then when Ryzen came along and actually delivered a new and competitive product we got this wonderful thing called competition.

My opinion at least is that DDR5 will be a lot more expensive than DDR4 to begin with. DDR5 DIMMs won't be any higher frequency than DDR4 modules to begin with but they'll definitely come with a premium. This happens with every DDR generation, DDR4 didn't become worth it until a couple generations in. You'd be hard-pressed to find anything faster than 2400MHz during the first year, which DDR3 already hit for cheaper. PCIe 5.0 will also be completely unused in anything in the consumer space for years. The datacenter is just now utilizing the full bandwidth of 4.0 with devices like Honeybadgers and dual 100Gb NICs. It might be useful for bifurcation but that won't be a thing in the consumer space either. Personally I'll see if Zen4 is worth it in regards to performance and core counts, DDR5 and PCIe 5.0 is mostly irrelevant to me. If this 29% figure is true I might just upgrade (though I already have a 5950X and definitely don't need to..)

again just seems like this made up by someone who wants people to be ultimately disappointed with AMD

Same like Zen 3 had like 50%+ more than Zen 2 and at the end was like 10-15%.

i.e. those AMD presentation slides.

I think that you are confusing things, AMD never said 50% IPC gains for CPUs, but they did say 50% efficiency gains for GPUs compared to previous generations. AMD never once, that I recall, stated 50% gains for CPU performance, only efficiency gains, i.e. less power to do the same amount of work. If you compare zen 3 to the original zen cores there might be a 50% IPC increase but that is not gen on gen but one gen versus the original gen.

Ok, so they indicated 50% gains with League of Legends, is that strictly IPC, better coding to work with Ryzen uArch, higher clock speeds, faster memory support, all of the above plus other things? Those are gaming improvements and for a select few title that are benefitted so generously, I'm speaking of general CPU performance. Average all of those numbers out between games and where does that land you with gen on gen performance gain?

They can do the same with Zen 4 like in this image. Picking the best example. I doubt Zen 3 is 50% better than Zen 2 in LoL tbh.

You are saying nonsense. 50% for League of legends in a one game scenario not overall performance.
And they didnt lie about it. 5900X has a 50% increase in performance in that particular case.
The IPC gain from zen 2 to zen 3 was 19% and that was also accurate.

Yes, you are. Numbers for individual games is a whole different thing.

AMD said 19 %, nothing else.

That image also shows a mere 5 % in another game = not picking the best example.
I doubt 50 % higher IPC as well, but this doesn't come from AMD.
