Mouser down in Mansfield has a pretty good supply of RPi 5B w/ 4GB of RAM. The 8GB boards are still on order.

They sure did but those "cores" were really more like arithmetic units and I believe they were all programmed to do the same thing at once. Thusly, they weren't quite like another core.? ?A Cray was SIMD -- Single Instruction Multiple Data -- one instruction with multiple data items.
To quote Wikipedia:

Mind you the CPU that fed this vector processor was something like a Data General Eclipse (I've also heard of VAXen) being used at the MCU which setup the vector processing and fed the CRAY-1 with all the data.
Even with a single core at 2-3 GHz, a RPi would do some serious a$$ whooping on this 1974 design.? :D

Re: RPi 1B faster than a Cray-1?
80Mhz was a boatload back then. Affordable gear end of the 70s ran at 1-2,
maybe 4MHz tops.
Gotta wonder what it would take to emulate a Cray-1 so that it matches the
original's performance.

Dallas Microcenter -- RPi 5B 8GB in stock
I just checked and the Dallas Microcenter has 7 RPi 5B's w/ 8GB are in stock. I'm sure they'll go quickly! Alas, no power supplies nor official cases.
Also, RPi Zero2W's are in stock, for a change, as well! Their website says +25 available.
