MLiD "Leaks".
No SMT4 this time?
Anyone that follow the news/rumors and actual leakers on twitter, can come up with that list.
This guys is a BS artist.
Exactly, it's just speculation based on stuff found on Twitter, Reddit and various forums. The "business model" of these "leakers" (both on YouTube and various websites) is to jump on every trend and create click-bait headlines, wild predictions etc. Their so-called "leaks" are all over the place, and people tend to forget all the mispredictions.
The few times they are right, then pretty much anyone could have reached the same conclusion.
People need to use their common sense and see through this. Pretty much all these leakers claim to have numerous "sources" inside Intel, AMD and Nvidia. But think about that for a moment; a real source with access to useful information under NDA would risk losing their job and could be facing a large lawsuit for leaking this, and they are supposedly doing so regularly to nobodies on YouTube with nothing in return?
In reality though, they are pulling all of these "leaks" out of their tuchus.
Isn't this the same guy that basically covers anything from 5~50% "IPC leaks" with his BS videos, he's like the YT version of WTFtech
That's only because he covers pretty much the entire spectrum
Yeah, his "IPC" estimates are all over the place, even for Alder Lake he has been posting claims at ~10-30% at various times, claiming it to be accurate at the time. But in reality though, real IPC is determined by architecture, and is actually known fairly precisely at the design stage, it's one of those metrics that will not change (unless they have to disable features etc.).
His claims in this video about Zen 4 not being design complete, and "things" can change clearly displays he is clueless about how microarchitectures are developed. The features of an architecture is decided
before the design is begun, no major feature can be added far into the design process. Things like AVX-512, SMT4 etc. are fundamental design features that affects the entire design of the pipeline. In the past, he has claimed Zen 3 exists in SMT2 and SMT4 variants, if this were true, then these would have been developed as separate designs from the start, yet we've seen no evidence of its existence.
So remember this;
real sources who actually work on these projects would know these details, and they are not subject to change. Last minute design changes are just excuses used by "leakers", when in reality the features of Zen 4 were decided years ago.
But this guy usually takes the cake whenever he claims to know much more, but don't want to tell us yet for some reason.
Anyone can do this; claim to know next week's lottery numbers, but only reveal them after the fact…
Slightly disappointing IPC lift, just when AMD could have struck the hammer blow to Intel, still 20% is far better than most Intel IPC uplifts (combined, for the most part!) over the last 10 years.
No one should complain if we can get ~20% real IPC gains ever two years for a while.
That will be great, and result in noticable improvements in responsiveness etc.
And remember, you don't have to buy
every generation
It would have been good to see AMD drop one last AM4 CPU refresh, with a nice 10% IPC uplift.
"Refresh"?
IPC gains come from architectural improvements, so unless some feature have been disabled/tuned down due to a bug, you will not see any IPC gains from a "refresh".
But the real question will be if AMD has the ability or balls to up the core count on AM5.
I actually think it would be a bad move for AMD to do this, in the long term;
The majority of desktops CPUs are sold to system integrators, and most of their customers look at specs like clock speed and core count (and is blissfully unaware that those high-core 65W CPUs will throttle like crazy), so good "specs" on paper sells. This is why Intel (and probably AMD) is moving to hybrid CPU designs for the desktop, even though it makes little practical sense. It's hard to "go back" and sell a faster 6 core once your customers already bought a 16 core of the previous generation. There are a lot of great CPU improvements coming in the next 5+ years, but they will require a lot of die size, so building >16 core low TDP CPUs with just high-performance cores is unrealistic for the foreseeable future.
