Is it me or have we not even had the review embargo date leak yet ? think its going to roll into August?

Biggest difference is that the x870e chipsets will support much faster memory at XMP/EXPO settings.
How much of a performance difference it'll make remains to be seen, though I assume we'll see reviewers benchmark with 7200Mhz-8000Mhz DDR5 kits (or faster), which simply have no chance of working out of the box on EXPO/XMP on X670 boards with 4 DIMM slots.

We can only speculate but how high do you chaps think the 1:1 infinity fabric ratio will go on AM5?
Rumours currently have it at 6400MHz for the next gen.
I'm getting that upgrade itch but I want to only do a single mb/ram purchase for the whole DDR5 life cycle. Looking at 96GB ddr5 (2x48) but unsure if its worth splashing out more on higher speed ram. I do prefer just to set XMP (EXPO now?) rather than fiddle too much.
Worth spending more to grab some 7200+ just in case and set it to 6400 for the 1:1 ratio until the 10k series come out?
But I don't like the thought of looser timings like CL40 rather than 32. Does reducing the MHz also reduce timings on these faster ram modules automatically rather than manual fiddling?

Reducing the MHz does "not" reduce timings automatically !!!
You'd have to manually tune that ram dropping down from 7200 to get lower timings than the 7200 MT's profile.
Some higher end motherboards however have various profiles for various speeds and timings that you can just select and apply if you've lost / never had the art of ram tuning.
It's best to buy what you need now - rather than waiting for the "best DDR5" to be available.
I've been on DDR5 since late 2021, coming up to 3 years already. It started out with 6000Mhz being the 'high end', which official reviewers used for the 12900k reviews etc. 3 years on, the high end motherboards (2 dimm boards) support 8000Mhz kits out of the box.
DDR6 is just around the corner, I'd imagine Zen 6 and 16th gen from Intel will be on brand new DDR6 platforms, probably releasing in late 2025/2026.

New benchmark scores for the 16-core AMD Ryzen 9 9950X processor were revealed, showcasing its performance enhancements over previous models. The 16-core processor, identified as "100-000001277", utilizes two Zen 5 CCDs and one IOD, supporting 16 cores and 32 threads. This unit is backed by 80MB of total cache memory, comprising 64MB of L3 and 16MB of L2 cache, and operates within a thermal design power (TDP) of 170 watts. The Ryzen 9 9950X has a base clock speed of 4.3 GHz with the potential to boost up to 5.7 GHz. This boost clock matches that of the Ryzen 9 7950X, though the base clock is decreased by 200 MHz.
The processor's performance was assessed using GeekBench version 6.3.0, where it achieved a single-core score of 3359 and a multi-core score of 20550. The testing platform included the ASUS ROG Crosshair X670E HERO motherboard paired with 32GB of DDR5-6000 memory in a dual-channel configuration. In comparison to the Ryzen 9 7950X, the Ryzen 9 9950X exhibited a 14% increase in single-core performance and a 7% rise in multi-core performance. When compared to the Ryzen 9 9900X, which is a 12-core model, the 9950X was slightly slower in single-core tests but showed a 4% improvement in multi-core tests.

this is not exactly stellar performance, those with 7000 series chips not worth upgrading tbh not for 14%-16% anyway. Multicore performance is even worse, assuming this might be driver issue?

Also, they only shown high end, expensive mobo on the new chipset so far, with bits added that haven't been available in current gen - all that means that will be expensive and above current ones in pricing, like w tier higher because you get more fluff (but not more performance).
I have seen no confirmation for that at all, just rumors at best.
These work on current boards already just not 1:1 with CPU. That won't change on new chipset (reason stated below).
4 dimm slots not working today well are mostly the fault of the board (daisy chain topology of ram slots etc.) and not chipset's. Chipset has nothing to do with RAM, memory controller is inside the CPU for a long time now and is said to be identical in coming CPUs.

You can achieve that already on same boards with new UEFI versions (MSI has quite a few they claim this will work on).
I much prefer to set expo with a ram that's tested by MSI (as that's the vendor of the board I have now), where they also provide optimise timings in uefi tested by them with specific ram kit. Works great in my case, cut a lot of secondary timings by 50%+ and it's fully stable, on stock expo voltages. That's a bit of a matter of luck, I suspect. My CPU can for example only do -10 on all cores with undervolting and I can't be bothered to try and tweak that more - I just used the MSI preset for that, confirmed it's all 100% stable and be done with it.
IMHO no - there's no indication this will work 1:1 with new CPUs, 6400 seems to be the limit still. Ram controller in the CPU seems to be identical to current 7k series.
You should be able to manually reduce timings with clock but it won't be as straight forward.

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

Maybe, but Geekbench's MT Score is meant be very poor with huge variations between runs and it scales really poorly too. In other words, not what we would expect from any multi threaded benchmark.
Guess we will have to wait for more useful benchmarks or actual reviews.
Having said that, Zen 5's design goals seem to be server CPUs 1st, 2nd, and 3rd so i would expect MT, AVX512, and power at server clocks to have been the focus.

Wait, what? so the 16 core chip is only 4% faster than the 12 core chip? That's weird, be it as it may there is no point in the 16 core existing.
Wait for real reviews.

I'll say this, every new Zen leak is all over the place, this is no different to Zen and Zen 3 "leaks"
I think they are all making stuff up for clicks, one day has really good results, the next really bad, then really good, then really bad again.... its all just click bait.
