Yes, and 5 years ago, they had very little of it. I'm talking about the trajectory, and AMD seems to be getting the lion's share of new sales.
I hope for the best for AMD ... they make great products... I own several AMD machines.
But ARM and the trust built around it ... continues to eat their market .... I see Intel as having more of a fighting chance.
IF THEY RESTRUCTURE ... or whatever the fuck their strategy is.
I don't really see ARM as having an inherent advantage. The main reason Apple's ARM chips are eating x86's lunch is because Apple has purchased a lot of capacity on the next generation nodes (e.g. 3nm), while x86 chips tend to ship on older nodes (e.g. 5nm). Even so, AMD's cores aren't really that far behind Apple's, so I think the node advantage is the main indicator here.
That said, the main advantage ARM has is that it's relatively easy to license it to make your own chips and not involve one of the bigger CPU manufacturers. Apple has their own, Amazon has theirs, and the various phone manufacturers have their own as well. I don't think Intel would have a decisive advantage there, since companies tend to go with ARM to save on costs, and I don't think Intel wants to be in another price war.
That's why I think Intel should leverage what they're good at. Make better x86 chips, using external fabs if necessary. Intel should have an inherent advantage in power and performance since they use monolithic designs, but those designs cost more than AMD's chiplet design. Intel should be the premium brand here, with AMD trailing behind, but their fab limitations are causing them to trail behind and jack up clock speeds (and thus kill their power efficiency) to stay competitive.
In short, I really don't think ARM is the right move right now, unless it's selling capacity at their fabs. What they need is a really compelling product, and they haven't really delivered one recently...
It's not just node, it's also the design. If I remember properly, ARM has constant instruction length which helps a lot with caching. Anyway, Apple's M CPUs are still way better when it comes to perf/power ratio.
Yes, it's certainly more complicated than that, but the lithography is a huge part since they can cram more transistors into a smaller area, which is critical for power savings.
I highly doubt instruction decoding is a significant factor, but I'd love to be proven wrong. If you know of a good writeup about it, I'd love to read it.
Here, I've found an article. M CPUs are also much more integrated, like a SoC, which gives them further performance/power advantages sacrificing extensibility.
Lol
The intel atom had a 4w tdp ... a snapdragon 855 has 5 w tdp ....
Intel is out of the smartphone market because Google built and optimized...( not as much as Apple ) ... android for the arm shit.
This fucked everyone and helped android... since now we are dependent on the chip vendors . Android can't be replaced on the damned things ... and every 3 years you ha e to buy another piece of crap.
