| Wasn't Ampere just bought by Softbank?

| Agreed. The ARM AGI CPU supports a newer version of the
| vectorized instructions and has matrix math extensions that
| the AmpereOne M doesn't. Also has almost twice the memory
| bandwidth. One paper at least, the AGI CPU seems like a
| better choice for AI workloads. Ampere is really pushing the
| AI workload use cases for the AmpereOne M, so this really
| makes their lives a lot harder.

| I'm a chip designer and a chip this complicated takes about 3
| years from start to actual silicon so it would have started
| well before Softbank started their acquisition process of
| Ampere.
|
| The press release says it was co-developed with Meta who has
| a growing custom chip team. Normally these chips like
| Amazon's Graviton or Google's Axion are designed for their
| own data center use only and rented to customers. This ARM
| chip sounds like Meta and other companies will all be able to
| buy chips for their own data centers.
|
| I'm guessing Softbank will get ARM and Ampere to align on
| future chips or just merge Ampere completely into ARM.

| ARM naming a chip AGI is either the most confident product launch

| Yeah seems like competing with your customers is a bad idea.

| It really is a choice for Arm to use their 2023 based mobile X4

| V4 cores should be out this year using X925 and C1 Ultra-based
| V5 will probably be 2027-2028.
|
| I suspect that X4 is already fast enough to beat EPYC in per-
| core performance when using the whole chip. ARM caught
| up/passed x86 in IPC all the way back around A77/78 in
| 2019-2020. They are now much faster per clock and hitting about
| the same all-core clockspeeds as standard EPYC (let alone zen5c
| EPYC).
|
| The big issue is that Graviton5 is already starting to hit the
| market and uses the same v3 cores. A lot of marketshare for
| this chip will probably come from taking Ampere customers.
