I think he means to say that RAM speed is meaningless when the required data cannot be found in RAM. That's when the perceptible delay is felt. If more RAM allows more data to be held in RAM and prevents going to disk, then in that case, it's better to have more RAM than speedier RAM. This obviously is for limited cases where the application preloads the entire working set into RAM and then works on that exclusively, without needing to go to disk until the task is finished. He does have a point that speedier RAM may not help in limited RAM capacity scenarios
Sure, this is true. Things are slower then RAM runs out. I agree. Not what was said though and that's not really an interpretation thing, it's just not what was said, like at all.

Yeah, everyone knows to wait for:

1. Arrow Lake
2. Discounts
3. X3D
4. More discounts

(Probably in that order)
Arrow late is much lower in this list. I don't think anyone is looking forward to intel products, are they? Appreciate this makes me seem like a fan of AMD but like, I doubt the current mood is pro intros next release. Apart from that I think your order is nailed on.

Why are people stating 2027 as fact all of a sudden? 2.5+ years would be insane and incredibly shortsighted. The competition isn't sitting still. Could they do a Zen+ on N3 where they beef up the core followed by Zen 6 where the finally handle the uncore? Or they other way around?
I don’t believe Zen6 is 2027 for one second.
It has to be 2026, because of market pressures.

It's the Radeon impact. Even if you don't want to buy Radeon you hope they're competitive so Nvidia will lower its prices and launch better versions sooner.

Except it also applies Intel. With AMD having higher MSRPs and holding back its X3D parts.

That figure for the 7950X is really not accurate. I see 3250-3300 single with my 7950X at stock 6000C30 EXPO in windows 11

Edit: 3100

That's a great point and it's my error. I usually pick the highest score, but somehow I picked lower scores for both the 7950X and i9-14900K.

Notebookcheck now has a higher score in their 7950X review database (3075 1T points), which seems much closer to yours. Updated.

Well, that does bring down the GB6.2 1T Pts / GHz uplift from the 7950X → 9700X down to 12.9%, which is not as impressive.

AMD 6800H20634.70043961.7%

610 (9700X) / 564 (7950X) → a good 12.8% uplift in Pts / GHz. Mobile chips are often a tad lower.

EDIT: forgot my sources! TweakTown for the 9700X; Notebookcheck for the HX 370. The rest are from Notebookcheck's review database.

EDIT2: fixed the 7950X & i9-14900K; Notebookcheck's database has higher scores already on their latest review units. And the i7-1365U & i5-1255U got mixed up somewhere. For reference, I chose the highest score NBC has; NBC has reliable methodologies and has access to GB6.2, which most don't now that GB6.3 has released, so it's more repeatable esp. for older Arm cores, even if it is a tad gimped for SME-enabled cores.

Got a duplicate for the Intel i7-1365U.

Rec'd for "Radeon Impact". I would have also accepted "Radeon Effect".

AMD would have been better off doing their core wars thing they promised generations ago. 8 core, 16core, 24core and 32core Zen 5 would have solved things this generation. Ultra low power for efficiency. I think AMD will fix a lot of the problems with Zen 5 via bios updates. Zen 5 will definitely see a Zen 5+ silicon upgrade to N3P or some variant in 2025.

The reviews out there are very very bad for Zen 5. Add to it that Arrow Lake is all new silicon that will dramatically reduce power consumption with 20A.

As a consumer it would be nice, but they'd have the MT performance crown locked tight already with 24 so from AMD's perspective, not much reason to go beyond that. Beyond that, I would have liked to see AMD move to triple channel with AM5. Would have been a huge boost to mobile graphics performance also. Econo-save desktops and laptops could still stick to dual channel.

>16 cores may finally make a lot of sense with Zen 6 given faster memory support and possibly a better cache regime. Or perhaps a cluster of 4 LP cores on top of the usual 16 full fat ones. I doubt consumer Z6 has the full 512-bit AVX path either, which would reduce the case for it needing huge bw a bit.

A 8 Z5, 16 Z5c desktop SKU might make sense if Intel comes on strong. Would be memory bw limited for a lot of tasks, but not all tasks are bw constrained. The shape of the 3nm Z5c die might not work well on AM5 though.

Frankly I don't think AMD cares about the consumer desktop market very much.

They know the gamers (myself included) will wait for X3D. Meanwhile the AI and server workloads show sometimes bananas increases in performance (and at lower power!) so they'll be selling all the Epyc chips can make. It's pretty clear based on where the increases are that this is a server first chip. We just get the scraps.

If the X3D chips run clock for clock with the standard Zen 5 CPU's. They would have a real winner.

I may consider upgrading when the next 3D chips are out. Depends on performance over 7800X3D, and pricing as well as general issues being sorted out, or not.

I suspect that even if the 9800X3D doesn't meet the 9700X in clocks, it will still beat the 7800X3D in gaming due to arch changes, cache, and some clock increases, which would make it the the new gaming flagship CPU.

As much as I would like this, what would be the point of the regular version? In that case they should have just skipped it entirely.
If you read one of my previous posts. I said just that. No need for standard Zen 5 CPU's without X3D cache. In yet another post I pointed out that Intel said X3D cache is not groundbreaking. Intel can add L3 cache to their CPU's just as easily as AMD.

Unlike 9700X vs 7700/X, I expect the 9800X3D will have a substantial clockspeed improvement versus the 7800X3D. Unless AMD screws the pooch and selects 65W as the TDP.

AMD is on their 3rd generation of X3D cache. The issue was heat close to the L3 big load of (96MB) v-cache. The heat issues are remedied by clock regression. This should be solved by the time they release the 9000 series of x3D CPU's. Those extra core clocks are a big deal when they are missing and a big deal when a CPU has the full boost.

I can beat Michael Phelps in swimming too, I just let him win for reasons.
