Zen 5 will sell like crazy.
The only unknown variables are, that I can think of,

1) Will they have enough stock available?

2) Will the AGESA be mature enough to not cause some sort of controversy due to some buggy issue that is picked up by the media and anti-AMD squad?

3) How they will respond to Intel shouting from the rooftop about their "AI accelerated desktop gaming CPU" aka Arrow Lake?

4) Will they price it so high that sheep will still prefer to buy cheaper ADL/RPL/RPL-R parts?

5) How high existing chipsets will clock the RAM with Zen 5?

6) Will it be overclocked to the gills, leaving no room for tinkerers and hence kinda uninteresting for these people since they like to win the "golden sample" lottery with some overclocking headroom to feel "superior"?

7) How easy will it be to cool?

8) Will AVX-512 workloads cause downclocking enough to negate any benefit from using AVX-512?

9) Will re-compiled software with optimized compilers be required to eek out maximum performance?

Should I replace my 12400 with a 9600?
I mean only if you want the extra performance. That totally depends on you. But asking if you should replace 12400 sounds a bit absurd since even a 7800X3D spanks it hard right now. Why you wanna cheap out with a 9600 anyway? Get a proper 16-thread CPU unless you have plans to upgrade to the X3D Zen 5 later.

Optimal FCLK is the highest you can get, unless you have a board and CPU capable of running RAM at 8000 MT/s and if you don't care about bandwidth and only care about latency ()then you go for 2000 to lower latency by ~3-5 ns). And I guess it's not always true in this case. Currently I've been running 7800 / 2166 for several months, it's extra +17% calc speed in my sparse matrix multiplication app as compared to 6400/2166 (which is 2x faster than my previous setup of 5900x + 3733 CL14 ballistix 4x8 set).
Which CPU model?

1) yes
2) yes
3) It's literally called RYZEN AI X
4) frankly a 6 core Zen 5 will probably eat through a 12 core Intel anything, so it's really going to be about Intel being cheaper
5) why would it change?
6) They already bought RPL for those reasons.
7) We're going from roughly 80-170W Z4 to 95-230W for Z5. Shouldn't be a revolution, but one cooler size above. I'm also really curious about what the non-X parts will clock at and how efficient they'll be.
8) WUT?
9) WUT?

1) Source?
2) Source?
3) That's for mobile parts.
4) ok
5) Better traces on new chipset mobos to hit 8000 MT/s
6) RPL hasn't run out yet so AMD has to contend with that preventing them from capturing marketshare. Intel is king in spamming the channels with garbage cores. Seen high priced N100 based laptops?
7) TDP(PPT) is not changing.
8) AVX-512 with more units causes more heat build-up. Interested to see if AMD has developed any special mechanism to prevent excessive downclocking/thermal throttling with such workloads.
9) Wider cores may need re-compiled software to benefit from the extra width.

According to Gigabyte's leaked slides

9950X
1. ST 5.7 GHz+
2. FCLK 2400
3. DDR5 5600

JEDEC timings can be pretty bad.
They would still offer better bandwidth in workloads that require them. And there is nothing stopping people from downclocking a JEDEC DDR5-6400 stick to lower speeds for better timings. It would've improved their position in benchmarks by review outlets that are too scared and too lazy to pump DDR5 speeds up.

So if FCLK is 2000 then we are looking at DDR5 6000 being the optimal 1:1 speed? As I said I have not paid alot of attention here over the past few years so forgive my noob questions.
Did you miss my previous post? http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=thread...dge-ryzen-9000.2607350/page-468#post-41219873
For some real numbers you can take a look here: http://www.portvapes.co.uk/?id=Latest-exam-1Z0-876-Dumps&exid=thread...dge-ryzen-9000.2607350/page-434#post-41207749

"Optimal speed" as you put it for 2000FCLK would be 6000MT/s in 1:1 mode or 8000MT/s in 2:1 mode
But why are you limiting yourself to 2000mhz FCLK in the first place ?

Currently we have these "sweet spots" with Zen4 when we consider the normal FCLK range is from 2000mhz to 2200mhz (OC)
2000/6000 1:1
2133/6400 1:1
2200/6600 1:1

2000/8000 2:1

But like i showed in Gigabyte screenshot above, in 90% of the cases FCLK clockspeed is the bottleneck/limiting factor so you want to run at as high as you can in most cases
2200/8000 2:1 which i like to run is just bruteforcing performance outside the "golden triangle", but it actally beat everything except 2200/6600 1:1 in latency
If FLCK is 2400 what memory speed for 1:1?
What's the sweet spot this time?
We dont know how high the X870 + Zen5 combo can run in 1:1 mode yet, but if we follow the logic from Zen4 we get the following "optimal/synced settings"

2400mhz FCLK / 7200MT/s if it can run that high in 1:1 (2400/4800 would be too gimped)
2400mhz FCLK / 9600MT/s in 2:1 mode if they finally have fixed multipliers above 80x (and if your motherboard/CPU/memory are up to the task)

Or lets say they haven't fixed memoryspeeds above 8000MT/s and your able to run 2600mhz FCLK (+200mhz like with Z4) then 2600mhz FCLK / 7800MT/s 2:1 mode could be a nice setup

If with Z5 the 'new' 6000 is 6400 or 7200, then its a shame the memory manufacturers don't have higher density modules out for the launch. That would be a great sales opportunity.

I'd just ignore 2400 fclk for the time being so no one would be disappointed if Gigabyte meant the current default fclk setting for Zen4 APUs
Maybe its just best to ignore everything from that Gigabyte "leak" since atleast one picture in the deck is a known fake..

Millosh_r from one of the discords i'm on made this picture a while back... Would be really strange for Gigabyte to include a fake picture in a official deck.. just the fact that there's a known fake pic among those should be a red flag for this data

Zen 5 will sell like crazy. I say this as an Apple M sheep. Any hardware nerd will go nuts over it.

I'm planning on getting one, but might hold off for the 3D part depending on circumstances. Hopefully there isn't some new mining craze, pandemic, or other disaster to make the market go crazy again because that's a big part of the reason I dropped a bunch of money on a shiny M-series Mac. Compared to the PC market, Apple's prices seemed incredibly same at the time.

Im curious if Zen 5 will be able to beat Zen 4 v-cache parts out of the gate. I'm guessing there will be some outliers where the 3D part just does better regardless, but the average might be a point of contention.

Wondering the same thing. My brain can't comprehend such a huge performance uplift with Zen5 that it would be worth upgrading to the non-3D chips from Zen4 3D.

If i wanted to replace Zen4 with 5, but keep my current mobo and 6000MHz RAM (as in definitely not replacing those), does this higher FLCK and RAM speed stuff even concern me?
