Neither have I...Not sure about node, but how clocks or power can be "standardised" ?)
Or may be "iso" is kind of e-slang synonym of "the same" in this context?
I just never seen using the term "ISO' in this context in any publications.

It's e-slang of the ancient Greek. :-)Or may be "iso" is kind of e-slang synonym of "the same" in this context?
ISO is also deliberately named after the Greek word. Because a standards organization is making things equal (and they wanted to avoid having separate French/English initialisms).ISO is too easy to confuse with iso. But at least he didnt say homo.
ISO is in fact just one of many international SDO's (Standards Development Organizations). There are many others, such as the IEC, ITU, and JEDEC just to name three.ISO is the international standards office so iso clocks or iso node or iso power is just short hand for standardising the given parameter.
What? If someone says iso process it simply means equal process. Iso as in isosceles not International Organization for Standardization.It's not really correct to say something like "ISO node" unless there is actually an ISO (or joint ISO/IEC) standard on that particular topic. Better to refer to the specific SDO publishing the relevant standard, assuming that we're talking about an actual standard, and not just some hand-waving that some number of people agree on.
Zen 4 had a much higher power limit, and was made on a custom N5 process. Both the process and the high power limit helped Zen 4 shine. AMD also was able to optimize the design to better scale with power (to a point) though from a frequency standpoint they are definitely still behind Intel.i see, thank you for explanation.
Why does the shrink explain the bigger perf increase in MT in the 5950x > 7950x case? I mean, the shrink does not result in more cores for 7950x, that would explain it, and as far as power-headroom goes, is that not reflected in available clocks? Which got increased about the same in both ST (4,9>5,7) as MT (4,4>5,1) case between these generations. Is it cause of the 105W to 170W TDP increase?
I'm guessing the LP cores would be too weak to handle gaming stuff so maybe they are just meant for OS threads. Then the big cores don't get interrupted by having to relinquish control and give their time slices to the OS threads. Should result in fewer hitches and more smoothness in frames.
I have not had time to keep up with rumors lately so perhaps this has already been discussed. I am not searching back through ~300 pages of speculation.Yes. Note that Zen 5 and Zen 4 are on similar processes. The process used for Zen 5 is technically better, but the savings are offset by larger cores.
Without a major shrink, Zen 5 cores will need more thermal and power headroom for nT and thus nT gains are usually smaller in those types of cases.
tl;dr
Single core gains are not power limited
multicore gains are and bigger cores means more power needed.
Turin use the same die as Zen5 thus 16 pcs 8xZen5 = 128 Turin cores.I have not had time to keep up with rumors lately so perhaps this has already been discussed. I am not searching back through ~300 pages of speculation.
I see Turin information saying 128 Zen 5 cores or 192 Zen 5c cores. 192 Zen 5c cores make sense (16 cores * 12 CCDs). How do we get 128 Zen 5 cores though? Is this known? It seems like it needs to be 16 cores * 8 CCDs, implying the existence of a 16 core CCD with Zen 5 cores. If they are significantly larger, then I don't know how reasonable that is. Other option is 16 separate CCDs with 8 cores each. Does the IO die have 16 GMI or only 12?

Consoles really don't need that, they're not laptops.Main benefit would be idle power.
It's a tricky challenge yeah.This looks awfully dense, particularily for the package routing on the same socket as Genoa
Yea it's the same and very basic still.Will thet use the same I/O die layout or use some famcier packgaging?
Unless one is counting keystrokes, why not just say "equal" or "equivalent", without introducing confusion? or indeed "isometric".What? If someone says iso process it simply means equal process. Iso as in isosceles not International Organization for Standardization.
I mean this is a technically oriented thread, we're talking about the fine details of microarchitecture and how they matter for these products/devices going forward.Unless one is counting keystrokes, why not just say "equal" or "equivalent", without introducing confusion? or indeed "isometric".
To be fair the post in question did erroneously capitalize it (autocorrect gone too far?) which caused some confusion.I mean this is a technically oriented thread, we're talking about the fine details of microarchitecture and how they matter for these products/devices going forward.
I'd really assume the people trying to browse and read these threads would have the ability to parse technical jargon.
Heck throwing "iso node" into the search box gave me results of people saying it as far back as 2014. I think some users just need to exercise their context-clues muscle more instead of trying for semantics.
Yep. This use of the prefix "iso" to mean "same" is very common in engineering. I typically deal with isothermal (same temperature), isotropic (same physical properties), isocontour (same line or surface on a plot), etc.Seems likeliest that iso is just shorthand for isometric which is Greek for 'equal measure'.
This applies cleanly to all uses I have seen in the tech world like iso clock, iso node, iso area etc etc.
While this semantic discussion can be fun are zen4 and Zen5 build on the same node?
I thought Zen5 was on TSMC 4nm?
So not on iso node?Zen 5 desktops will be on N4 (N4P I think), mobile as well I believe. Zen 4 desktop was N5 and mobile was N4. I believe the 8000 series refresh of Zen 4 mobile is on N4P already.
Not on desktop, no. Mobile should be on the same process as Zen 4 refresh.So not on iso node?
