AMD Zen 5 rumours

According to AMD marketing the 9950X3D is faster than the 9800X3D in games.
Hoping these will be freely available on launch.


It seems it might be blows traded each way, but likely only by the 9950 not the 9900

Hard to imagine the 9950X3D ( or 9900X3D ) will be significantly faster than a 9800X3D at gaming. After all, one of the CCD's in the 9950X3D is in essence a 9800X3D. If the higher base clock frequency is maintained, then the 9950X3D could be fractionally faster, but if core "parking" is still an issue then that ( along with the added latency between the two CCDs ) could make it fractionally slower.
 
How does gaming work on the 9900X3D (for example) given that both CCDs have 3D V-Cache? Does gaming workload span across both chiplets now?

9800X3D is 1 x CCD (1x8C) with 3D cache
9900X3D is 2 x CCD (2x6C) only 1 with 3D cache
9950X3D is 2 x CCD (2x8C) only 1 with 3D cache

dual CCD chips still need parking to stop gaming running on the 'wrong' CCD, as such the 9900 is slower than the 9800 as it has fewer cores for gaming.

Yeah assuming no power/heat issues with the higher core count then it might be a tad faster, but I'd imagine it'll be very close in gaming.

As above, it's only one 3D cache core isn't it?

It's a hard sell, same with the 7900X3D, as only 6 cores for gaming is likely to be an issue in the near future.

Cost and 'faff' - The CCDs are 8 cores, so they use 2 'defective' CCDs where 1or 2 cores don't work and fuse them off.
If they used 8+4 they'd need to:
a) Use a full working 8 core that they could use in the 9950X3D/900X3D (3D cache is expensive to add so you want to use things efficiently)
b) Potentially cut off 2 working cores to make a 4-core.

They use 6 cores for 9600X already so it probavbly a balancing act of yields vs demand but I'd imagine they have fewer 4 cores that 6 cores

Core parking wasn’t an issue as long as you followed the correct steps when installing the drivers etc.

Sorry, have to disagree on this. Later BIOS updates improved the situation, but it was still an issue for many people. A quick Google search or trawl through Reddit etc is proof.

Have AMD definitely confirmed the 9900x3d will be 2x 6c and not 1x 8c and 1x 4c?
Haven't seen anything official, but that's the configuration of both the 7900X3D / 9900X and as far as we're aware the only real change in the architecture is how the 3D V-cache is implemented.

I owned the 7950x3d and had no issues. Game bar enabled, balanced power plan, chipset drivers (from AMD website) and make sure game bar is updated. Every now and then you might have to tick a box “remember this is game”.

That’s it!

Reviews are out tomorrow.
So hopefully see the performance.
If it has the power of the 9950X with the gaming performance of the 9800X3D, then I will be very happy.
Just hope there is plenty of stock available.
 
I was waiting for the 9950x3D myself, but I put my order in the other week for all my stuff and ordered the 9950x. I don't game but I wanted it for encoding would it have been worth waiting for the 3D version? or would I just be better off saving the extra money and keep the 9950x.

I still have a few parts on pre-order so still got time to change it.

i want a 9950x3d to replace my z690 system but lack of proper high end AM5 MBs that have 10Gbe and can use multiple m.2s without limiting my GPU to 8x is holding me back

im guessing we wont see new MBs till zen 6
