AMD Zen 5 rumours

[tamzzy]

i think at stock, the 9800x3d will only be 5-15% faster than the 7800x3d

my reasoning for this speculation is:
going from a 5800x to a 7700x is a 15% performance bump
going from a 5800x3d to a 7800x3d is a 20% performance bump (+5% on top of vanilla)

so, if the performance uplift of a 7700x to a 9700x is only 5%, then i would assume a 10% increase (5% + 5% for the x3d portion)
the only way i can see this improving is if zen 5 is much more efficient than zen 4 and allows the 9800x3d to keep the boost clocks higher and for longer, given that the x3d sits in between the cpu and the heat spreader

putting this out here so i can either be proven right or be laughed at when next month comes round

Sargatanas2511, I'd certainly think so, I'm going to be upgrading from a 5900X and hoping for a solid jump up in game performance.

edit to add reply name for clarity.

I'm expecting 10% overall personally, wasn't worth waiting for and got a good deal on a s/h 7800X3D so took it

 

[Littlenose]

the 7800x3d price has shot up recently, I believe due to stock levels.
Is it likely to come down again when the 9800x3d releases, or has manufacture stopped ?

We're kind of expecting that to be the new place for it and the 9800X3D to come in at $499/549 now...

"oh look, the 9800X3D is only £50 more than the 7800X3D"

£440 > £490

instead of mere weeks ago where it would be £315 > £4xx

same
got mine for £230 with a 2 year warranty #winning

 

[Littlenose]

Thanks for that.
If the 7800x3d is likely to sit at £430 instead of down to £350ish, then I'll keep the will drop the extra notes and get the 9800x3d

AMD Ryzen 7 9800X3D Tuned To 5.6 GHz Across All Cores, Up To 35% Faster Than Stock 7800X3D

AMD Ryzen 7 9800X3D CPU is an impressive overclockable chip, reaching up to 5.6 GHz across all cores which is much faster than the 7800X3D.

wccftech.com

Looks fake to me with cinebench showing the base clock at 4.07ghz for the 9800X3D which is a lower base clock than the 7800X3D.

Infact its probably just a 9700X ES, the 9700X which has a base clock of 3800mhz due to the low 65w TDP so 3800 + 200 Fmax so 40x101.75 BCLK = 4070 which lines up perfectly with the 4.07 in cinebench.

I am still on Zen 2 and have been waiting for this to upgrade. Should be well worth it!

Even if it isn't much of a jump over the 7800X3D, I expect it'll give me a pretty solid jump from a 3900X.

Same here, still on a 3900X. So, if I do elect to jump to one of the more recent Zen chips, then this is one that might tempt me.

X370 board for me so I don't even have SAM or anything like that. The performance update should be huge with all the little changes and IPC increases from Zen 2 to 5.

Some X370 boards do actually support SAM and PCIE 4.

 

[Varys]

Will be picking up one but struggling to decide on a board, especially when gigabyte is throwing around big performance claims. It’s between the Strix and Aorus Master for me

I’m sure all board manufacturers will have their own version of what gigabyte claim to be offering…

My Asus B650E-E Rog Strix which can be considered an old board now already has a special section in bios for AI performance boost solely with X3d chips.

I don't have an x3d chip to test but someone on here can probably test performance difference with it turned on or off, but I suspect its all BS.

My X370 does have SAM, No PCI-e gen 4 though, an old beta BIOS enabled gen 4 but AMD put a stop to that.

 

[Curlyriff]

Think I'll be sticking g to the 5950x for another generation honestly at this point.

The boards need the capability for the signaling to remain stable. For many motherboards that requires repeater to be fitted.

AMD Ryzen 7 9800X3D box leaked, 2nd Gen 3D V-Cache teased - VideoCardz.com

AMD Ryzen 7 9800X3D launches November 7th No Ryzen 9 9950X3D in sight. On November 7th, AMD will launch the Ryzen 7 9800X3D. We now have a new high-resolution image of the packaging, which fully matches the previous leak. The key detail is that the box says Ryzen 7, and no other Ryzen X3D box […]

I know, it would have been nice though as I only upgraded as the PCI-e was gen 3 and so limited(number of lanes).

 

[Rob_B]

Was going to say what a nothing burger of an article but "2nd gen vcache" is intriguing. Any rumours as to how it could be different enough to earn that phrasing?

Edit after googling:

Plus the positioning of the TSVs within the L3 cache might stress out the CCD itself so it is speculated that AMD might go for a 2-Hi stacked 3D V-Cache design to counter the impacts.

AMD Granite Ridge "Zen 5" CCD Gets Beautiful & High-Res Die Shots, Reveals Brand New TSV Layout For 3D V-Cache CPUs

The AMD Zen 5 CPU powering the Ryzen 9000 "Granite Ridge" CPUs has received new high-res die shots from Fritzchens Fritz.

Double stacked would surely mean more heat, couple with higher clocks I look forward to seeing how they handle that.

Waiting on the X3D, upgrading from a Ryzen 7 5800X so should be a decent uplift in frames.
