AMD Desktop 8000 series

How about an AMD chip fabbed by Intel? Could be on the cards, I imagine Intel will be pricing aggressively to win customers

 

I can't imagine that ...
Intel chip designed by AMD fabbed by TSMC, yeah sure

 

Amd chip designed by nvidia with an intel GPU onboard manufactured by Motorola and sold exclusively at McDonald’s drive through

 

So one of those Egg Council creeps got to you too huh?

 

Depends on how legally independent fab and design companies are, though politics would probably put influence on a deal like that. TBH I can see the Intel fab rebranding in one to two years time if business from Intel's design house continues to fall. After all if they're not a big customer and having that logo inside is holding you back, what else will you do?

Politics from the US government might weigh in on any decisions like that, for example if there are major incentives/roadblocks put into place that make sourcing locally manufactured processing chips attractive or essential (perhaps as part of a political lobby to maintain cutting edge onshore semiconductor capability... or however the political sell would read), then such a deal between AMD and the Intel fab is well within imagination. But if I were AMD I'd probably pressure them to rebrand first at any chance. I can't see it on a cutting edge product line though given that the Intel fab technology is so far behind TSMC's.

 

Surely an ai algo will solve all these issues. And inform the consumers and or ceo / others.

Anywho. Intel 15th gen and yet another socket ffs.

And a 9 series ryzen imminent.

8 series on 4nm and an 8 /16 with decent boost clocks. Is what appeals to me at this point in time (atpit)

I read that Intel are ditching hyperthreading (again) for arrowlake

 

Desktop Zen 5 will be Ryzen 9000 apparently.

 

Gamermald had his adrenaline shots yet?

 

I'm not familiar with his channel, but I am sure there will be, if not already, an uptick in bombastic titles

 

Rumour: There will be 3 variants of Zen 5. Normal, Dense, and Low Power. The LP variant will appear in Strix Halo only, apparently, before the tech becoming part of Zen 6 lineup.

Noone seems to be sure if Zen5LP will feature the full ISA. It will sit in the SoC rather than being part of the standard ccds.

 

dropping what if they did drop something ?
avx512 and AI features ??
for the target market would it matter ?

 

Yeah... dropping AVX512 wouldn't matter. I think the possible relevant AMD patent mentions catching illegal instructions and automatically shifting the execution thread to a core that can handle the instruction.

It a set of low powered cores that are always on. One usecase which I have seen mentioned in context of Apple silicon that has tried this is voice activated AI. Your laptop is virtually idle, the main ccd's are completely switched off... so is the gpu and the npu... but something needs to be on to capture the owners voice and wake up the npu. It should be able to handle io as well, so keep any network streams and light weight processes happy.

 

AVX512 is gaining momentum. Particularly for video, 3D rendering and AI. AI is the hottest thing in the world right now.
Even for SoC AMD is not going to drop AVX512 and AI.

Some applications of SoC, like Tesla car interface, AVX512 and AI could be a game changer.

If you aren't interested in new features, AMD has Zen2 and zen3 and zen4.

But be aware soon non AVX-512 won't be able to use windows or Linux who will use AVX512 for cryptology purposes (SHA256,Serpent, twofish, SHA-512,chacha20,camellia, cast5/6), .net or .net framework, or Zoom/Microsoft Teams, or games, or video encoding on x254, x256, or web browsing (people have seen the performance increase from Palemoon), data compression, java virtual machines, etc. A lot of embedded applications need good encryption/compression performance and to handle video. AI is likely to use it heavily.

Ask people who have Mac M1 processors.. They don't have any AVX at all.

However, AVX-512 was never that well prioritized by CPU developers. Once AMD releases its new CPU's, I expect developers will actively swarm to a feature that makes performance 40-100%+ faster on CPU's that support it. Applications that were built around future AVX-512 support will have a massive margin from day one.

It then clearly rewards the pay off for implementing it.
Which is bonkers, than Intel is going backwards on instructions they introduced nearly 10 years ago. That are now finally paying off. For 10 years we have basically focused on just compatibility, not actually trying to get performance out of these instructions, we are finally getting the performance unlocked in hardware.

 

I didnt mean dropping AVX 100%, its in every cpu since my old 2600k
might be just a cutdown ?? drop the 512 bit width and keep them at 256 ?

the question remains, what would they cut down then ?

 

The first thread ive ever seen any complaint on AVX and Apple silicon is somehow in a thread about unreleased AMD cpus

 

We were talking specifically for a very low powered Zen 5 core called Zen5LP. There is no point for such an always-on LP core to have AVX since almost by definition AVX makes the power usage go up massively. Your standard Zen 5 core and the dense version (Zen5c) will still have AVX-512 and its rumoured to have massive gains in this compared to Zen 4.

In the post above, I even mentioned an AMD patent that can shift cores for an execution thread if this thread tries to execute an instruction that can't be run on the current core which matches the scenario of cores with different ISA's cooperating automatically.

As for AI, in both Phoenix and Hawk Point, there has been an NPU included and this will clearly continue across AMD's mobile offerings.

 

Removing AVX-512 from zen 5 is essentially impossible. You are creating an entirely new architecture. It would be easier to port Zen4 to do that job.

AVX-512 is integral to the Zen5 design, everything from the front end, the cache, the ALU and the FPU have been designed around it. It can't be removed. It could however adjust clocks and thermal budget while executing.. AVX512 doesn't have to spike power..

 

Thats right... its a different ISA.

Why? Zen 4 has AVX-512.

I'll disagree with your notion that removing AVX-512 is impossible and leave it at that

 

If it does surface without avx 512 I will transfer you $10. Please remind me.

The way amd has included functionality it isn't is a separate unit or core.

Amd isn't particularly interested in supporting very different x86 designs. They aren't Intel. 4c is small cache 4. Screwing around with core architectures is expensive and a waste of resources.

Avx512 time has come. Full Avx512 maybe import important than more cores or more cache or more clockspeed. Avx512 will unlock greater energy efficiency.
That's all, I think a lot of gamers and overclockers underrate it. Because of Intel's flawed implementation, and amd focus in other areas.
