AMD Zen 5 rumours

So far most tests I've seen of memory over 7000MT with 2:1 mode shown that in most cases timings matter more than speed. It's usually better to run 6400MT with tighter timings than the faster modules. But it depends on use case. There's a reason AMD said new CPUs have sweet spot of 6400MT 1:1.

They both have same memory controller apparently (current and 9k series), so should behave in almost the same (if not identical) way with memory

What about when you start to get to 8000mhz and above, is there a tipping point where running 2-1 mode becomes better than 1-1.

It reminds to be seen, so far I've not seen tests that would show definite advantage of faster memory Vs 1:1 one with tighter timings.

That's...not great is it.
Surely, suuuurely that's not right :/

But the 9950X only scored 20550, thats like 1 or 2% faster in synthetics, you're not going to notice any real world performance difference at all.

Depends how good the benchmark is.
I think there'll be a decent uplift in games given the decent single threaded performance.
 
ASRock just dropped another bios for my board, guessing there'll be others too. Second one this now for the new ryzen chips. This one says "9000 series optimisations." So go check people if you are planning on buying the new cpus, get your bios upto date. :)

I'm just flashing now.... Ooo errr.

AMD have said that Zen5 will not be faster than Zen4x3d in most games, on average. We'll see big gains in productivity and general compute, but will have to wait for Zen5X3D for a big gaming performance increase.

Hopefully Zen5X3D and ArrowLake from Intel launch together around the 5090 release, will be interesting times :D
 
After 2 generations of 3D Stacked Cache it wouldn't surprise me if AMD didn't some more development work on it for the third generation.
