Oh? What "SRF session Q&A" would that be?Well I don't have to believe, that's the literal answer Intel presenters gave during their SRF session Q&A.
He’s probably talking about hot chips.Oh? What "SRF session Q&A" would that be?
There will be if Intel never produces a meaningful number of these chips.Is there anything wrong with 288 Gracemonts at some 2.5Ghz ?

Two rules of pronouns would be broken in Abwx's post.I think you got the grammar wrong. "It" would be referring to the subject of the previous sentence.
Or another example: https://www.dummies.com/article/aca.../positioning-pronoun-antecedent-pairs-190485/Every pronoun should refer to a specific antecedent that has been mentioned and is close by. If the antecedent is missing or too far away from the pronoun, it can be difficult for the reader to understand what noun the pronoun refers to.
Rule #1 was broken; there were multiple antecedents. Anyone who applies rule #2 of being close by will be mislead since his antecedent was both the furthest away and also in a different paragraph. Being the subject of a sentence has nothing to do with properly using pronouns.One way to lose a reader is to let your pronouns wander far from their antecedents. To avoid confusion, keep a pronoun and its antecedent near each other.
Here is Anandtech's coverage of Sierra Forest in Hot Chips 2023:He’s probably talking about hot chips.
Technically Crestmont is based off of Gracemont. The Sierra Glen core is literally called “CME”, where Crestmont is “CMT”. Sierra Glen (CME) is a die shrink of Crestmont as far as I know (5 wide re-allocate though).
Crestmont is essentially Gracemont that went 6-wide and has a 6-8% IPC bump. It’s basically splitting hairs.
So Granite and Sierra can be thought of as a deconstructed Meteor Lake processor, with Granite getting the Redwood Cove P-cores, while Sierra gets the Crestmont E-Cores.
...Intel is revealing that Crestmont is offering a 6-wide instruction decode pathway as well as an 8-wide retirement backend...Meanwhile, new to the E-core lineup with Crestmont, the cores can either be packaged into 2 or 4 core clusters, unlike Gracemont today, which is only available as a 4 core cluster.
.@intel will first test high-NA EUV from @asml with the "18A" process node and use high-NA for the production of a "Intel next" node, tho no real timeline was given (I'd say after 2025). But it does look like Intel will be first on high-NA, after they were years behind with EUV.
Ye, we talked about this a couple months ago. The head of Intel's fab development (Kellher? IIRC) said that Intel 18A is able to use high NA EUV, but in order to reduce risk, they are also able to develop Intel 18A without High NA EUV. I'm pretty sure the default was that it would use high NA, but it looks like due to delays or cost they won't end up using it as originally planned.
No High-NA for 18A. Nothing new really but some people thought it's coming.
IPC increase was quoted to be 6-8% IIRC (read it somewhere but don't remember where lol). Doesn't sound too bad. A bit surprising that SRF isn't using crestmont, but it looks like the all core frequency reduction is greater than the IPC gain?Here is Anandtech's coverage of Sierra Forest in Hot Chips 2023:
H433x0n is correct Crestmont and Gracement are different, but not much different.

Two rules of pronouns would be broken in Abwx's post.
1) Pronoun antecedents should never be ambiguous. Everyone should instantly know what "it" refers to. Consider this sentence: "After removing the CPU from the motherboard, Joe NYC sold it." What did you sell? Will everyone agree on what you sold? Probably not. The "it" could be the CPU. The "it" could be the motherboard. No one knows exactly what you sold from that sentence. Thus, the Joe NYC selling sentence broke the ambiguous antecedent rule. That is the main problem we are talking about here. There were multiple possible processes that could have been implied in Abwx's post.
2) The pronoun's antecedent should be close by. The antecedent should never be in a previous chapter, previous page, or even a previous paragraph. An antecedent could be in a previous sentence, but only if clear. Look up far away antecedents. Here is one reference: https://www.trentu.ca/academicskills/how-guides/how-edit-your-writing/grammar-and-style/pronoun-agreement-and-reference#:~:text=Every pronoun should refer to,noun the pronoun refers to.

No, SRG is rumored to be ported gracemont, so you get the 5 wide rename but higher clocks iso power (because narrower architecture) , crestmont is wider. SRG was at first thought to be ported crestmont, but nah, it's ported gracemontIt's the same with Crestmont, just a month or so ago, they were claiming it is 5 wide allocate

Nowadays it seems they have found a way to make it 6 wide in allocate?
I just checked and just about every tech news site says Crestmont. Heck, all 3 of 3 of Anandtech's articles on the subject say it is not Gracemont. https://www.anandtech.com/tag/sierra-forestNo, SRG is rumored to be ported gracemont, so you get the 5 wide rename but higher clocks iso power (because narrower architecture) , crestmont is wider.

Should their customers really care about this? If the price is right, orders are fullfilled above or below table, they will not care.
What's next, caring about Intel's yields and profits while producing palm sized "chiplets" ? Let's leave those concerns to Intel's bean counters and stick to technical.

Do you have anything that verifies it is Gracemont?
Ah that's my bad. I guess I misremembered the exact range of values.4-6% reported by multiple sites, apparently this is what Intel told them. This modest improvement is more than I expected from Crestmont though. I thought Redwood Cove brings more and now it's the other way around Crestmont brings more IPC impovements than Redwood Cove? This was unexpected.
Ah that's my bad. I guess I misremembered the exact range of values.
That must have been someone misspeaking the number 5 instead of 6. Every major site that covered Sierra Glen at Hot Chips says it is Crestmont and not Gracemont. Intel even shared many slides listing the new Sierra Glen E-core features at Hot Chips. https://www.intel.com/content/www/u...-forest-xeon-press-briefing-presentation.htmlHotchips when Intel talked about Sierra Glenn.
