Of course. When you buy out all the capacity of the TSMC 3nm node for a year and use it to make huge, low-yield chips and charge a small fortune for them, you can get some performance advantages.
Intel's fabs are catching up, though, and have more money invested in them again. Ideally, we'll see a more competitive market soon.
- brucethemoose2 3y agoAnother factor is that Apple designs big cores exclusively for consumer apps on iPhones. There is no compromise for server workloads, high clock targets, chips with modest die areas, slow memory, dies without efficiency cores, AI SIMD and so on. I don't think any other company in the world can financially justify such a specialized big core, except maybe Samsung (who has failed in their ventures so far).
- Kirby64 3y agoDo they? It seems their system architecture between the A-series for phones and the M-series for their pads/laptops/etc is largely the same. It's certainly the same design facility.
- brucethemoose2 3y agoThe applications they target are very similar.
- TylerE 3y agoEditing 8k video and running a social media app on a phone are vastly different workloads.
- brucethemoose2 3y ago> Editing 8k video I would hope the GPU would be handling this. ...But honestly, they are not that different. Both are heavy media processing, and you would build the same kind of CPU core for either as opposed to (for instance) a database workload.
- sudosysgen 3y agoVideo encoding if you need the best quality still is done on the CPU.
- brucethemoose2 3y agoVideo encoding also favors Apple's wide, SMT free design. In theory chunked encoding gives you the best quality, and the best CPU for that is a bunch of little e-cores, but the only app I've really seen implement chunked encoding as a "max quality" feature is av1an.
- seanmcdirmid 3y agoBut editing 8k video in a social media app on a phone is a similar workload. And really, TikTok’ers are doing stuff like that with their phones these days.
- ksec 3y ago>use it to make huge, low-yield chips and charge a small fortune for them, you can get some performance advantages. 1. It is not huge, by CPU Core or by SoC Die Space. 2. It is not low-yield either. 3. Comparatively speaking, what Apple include their SoC as BOM / COGS isn't anywhere as high as Qualcomm charges, hardly a small fortune. 4. It is performing close but at a much lower wattage. That is not just coming from a node advancement but mostly microarchitecture.
- hu3 3y agoDo you have a source for these claims?
- genmud 3y agoLiterally every industry publication and BOM analysis since... the first iPhone?
- ksec 3y agoWhich one? All of these are nearly publicly available information or can be directly inferred. Except they are either from Annual Report, Investing Meetings, Court Documents, or actual Geekbench numbers. The problem is people read Macrumours or WCCftech and believe they have informed.
