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 do hope though that the same refinements are also brought to the 5800, 5900, and 5950 as XT forms for AM4, since I'm one of those just waiting for things to hopefully normalize come Summer as I eventually prepare this main rig to last 5-10 years or more (unless we experience a breakthrough in quantum computing, and we see the AMD Quantum consumer chips).
The Zen 4 IPC rumor doesn't sound too out there, but it'll be a generation I'm not going to be interested in personally. I do hope to see AMD continue to pushing the limits, and hopefully finding more production space along the way too.
We're referring to the OP and it's not enough for you. I'd suggest you ask the OP instead, or better yet, ask the sources. :) None of us came up with Zen3+, it's been out there for a while.Yeah, it sounds possible. AMD will need a new IO chip for DDR5 and they will make new chiplets sooner or later. It makes sense to combine Ryzen 5000 chiplets with a new IO chip and use it for one generation, before updating the chiplets as well.I don't see what we could expect here besides higher prices. 3000XT made absolutely no one happy. 100 MHz extra makes zero difference in the long run.The Zen 3 improvements were impressive, especially since it still was the same 7 nm, the same IO chip, and still DDR4. All those should be improved in Zen 4, although I wouldn't have too much hope about 5 nm in terms of improvements.
I knew AMD was going to release something on AM5 before Zen 4. And Figured it would be a Zen 3+ so you can have the boards out and tested in the wild. This also gives you time to work on the bios before Zen 4 launch. So the platform will be vetted instead of everything brand new for Zen 4.
And I don't think we are going to see a XT refresh on current Zen 3 models.
What a cool new name!
I know what you are referring to but Zen4 is confirmed by AMD Zen3+ isn't. aka fact vs rumor.AMD never said it will release zen3+. That has been taken from what happened with zen and zen+ but that was a different situation than now. This doesn't meaning it has to happen. It wouldn't hurt if it does happen.
Either way you slice it, I believe it when I see it.
But regardless, substantial IPC gains is certainly still possible. Just continuing expanding the front-ends with wider OoO windows, larger register files etc. and adding additional execution ports alone have a theoretical potential of ~50-100% IPC gains (if not more). Potential new techniques which improves ILP, like threadlets, can yield gains beyond that. And then there is certainly ISA improvements.
So it's not unlikely that we will see several new generations offering IPC improvements in the ~20% range.
As for availability of Zen 3, I'm actually more concerned about the stability issues which still remains three months in, which ruins an otherwise kick-ass product. At least they are steadily shipping out, even though shops may have several months of backorders.Actually not. IPC is an underlying constant, which we try to approximate using a wide set of representative workloads.
In addition, your pricing estimates are misleading. You are forgetting the cost of a CPU cooler. The AMD processor comes with one, not to mention Intel is harder to cool due to the higher power requirements. In addition, in order to get the most out of an Intel CPU you need a Z class motherboard (You can't even enable XMP on anything but Z class for Intel). The 5600X on the otherhand runs just fine on a $65 motherboard and you can still run your RAM at high frequencies.
Last you are quoting the inflated AMD prices, not MSRP. There's a reason the Intel CPUs are still in stock, they are worse in every metric often by a wide margin. Hell the 5600X matches in multi-threading performance to Intel's higher core count parts and consumes half the power while doing it.
If you want the best CPU on the market, you buy the 5800X / 5900X / 5950X (depending on core count need). If you want a budget CPU you get the 3600. The 10400f is a decent proposition and beats the 3600 in gaming by a small amount but at this price point people won't have a GPU that can realize the difference and in order to get that performance out of the 10400f you need a Z class motherboard. Your performance advantage is moot with a B class mobo. The 3600 beats the 10400f in every other metric though, so really you are buying it if you only care about gaming.Those will relax as the market returns to normal demand levels. Right now demand was placed at around 2.8 times normal.That's very expensive for a 3600. That said the 3600 still comes with a CPU cooler and can run just fine on a low end motherboard. In the end you are going to be paying about the same for the Intel and AMD platform. Retailers in your area seem to have up-priced the AMD CPU knowing this.
More like you read that in an article here and are now parroting it as if you had that thought.
I'm not saying that choosing the 10400f is a bad choice, but there's a few perks coming from zen2 and AM4, a more modern platform with pcie 4, and the possiblity to get a zen 3 for cheap after a while (especially when DDR5 is going to be costly, and not much faster for at least a couple years.)
We are equally getting screwed for not being american (besides the fact that zen 3 is far far more easier to get in Europe), but I still don't think that the 3600 is overpriced. The 3600x/5600x though ? big time overpriced.

Sorry thesmokingman, I couldn't resist, posting is a bit like smoking. Just one more.
Btw 10400f comes with a cooler and its performance doesnt get affected a single bit by using it.
Z490 motherboard? 120€ and you're set. Cooler for 10600k? Cyorig m9i and you are good to go. Still cheaper than 5600x+b550 motherboard.
Oh also forgot that you dont need b die RAM on Intel, wich is more expensive.
You can Say what you want, no One on a budget buys AMD right now. Plus... Stocks are awful anyway.
PS: yes there are common stability issues with zen3. Go on overclock dot net forum and look at the poll. The most recent chips have a high errors rate, at stock! Pure crap.
