32-bit CPU for the Wii U

Espresso is the codename of the 32-bit central processing unit (CPU) used in Nintendo's Wii U video game console. It was designed by IBM, and was produced using a 45 nm silicon-on-insulator process. The Espresso chip resides together with a GPU from AMD on an MCM manufactured by Renesas. It was revealed at E3 2011 in June 2011 and released in November 2012.

IBM and Nintendo have revealed that the Espresso processor is a PowerPC-based microprocessor with three cores on a single chip to reduce power consumption and increase speed. The CPU and the graphics processor are placed on a single substrate as a multi-chip module (MCM) to reduce complexity, increase the communication speed between the chips, further reduce power consumption and reduce cost and space required. The two chips were assembled to the complete MCM by Renesas in Japan.[1] Espresso itself was manufactured by IBM in its 300 mm plant in East Fishkill, New York, using 45 nm SOI-technology[2] and embedded DRAM (eDRAM) for caches. While unverified by Nintendo, hackers, teardowns, and unofficial informants have since revealed more information about the Espresso, such as its name,[3] size[4][5] and speed.[6][7] The microarchitecture seems to be quite similar to its predecessors the Broadway and Gekko, i.e. PowerPC 750 based, but enhanced with larger and faster caches and multiprocessor support. Rumors that the Wii U CPU was derived from IBM's high-end POWER7 server processor proved false, as it would potentially increase the manufacturing and retail cost of the system, and require a larger form factor. Espresso shares some technology with POWER7, such as eDRAM and general instruction set similarities, but those are superficial similarities.[8][9][10][11][12]

Will PS4 discs work on PS5?

The PlayStation®5 console is backward compatible with the overwhelming majority of PlayStation®4 games. That means an amazing collection of thousands of PS4™ games can be played on your PS5™ console.

playstation.com - Backward compatibility: PS4 games playable on PS5 consoles

The overwhelming majority of the 4,000+ PS4 games are playable on PS5 consoles. Select PS4 games will benefit from the PS5 console’s Game Boost, which may make PS4 games run with a higher or smoother frame rate. Although many PS4 games are playable on PS5 consoles, some functionalities that were available on the PS4 console may not be available on PS5 consoles. In addition, some PS4 games may exhibit errors or unexpected behavior when played on PS5 consoles. Before purchasing add-ons to play with your PS4 games on PS5 consoles, please try to boot and play your PS4 games on your PS5 console to see if you are happy with the play experience. PlayStation VR games are included among the thousands of PS4 games that are playable on PS5 consoles. Playing PS VR games on a PS5 console requires a PS VR headset, PlayStation®Camera for PS4* and a PlayStation®Camera adaptor (no purchase required). Visit playstation.com/camera-adaptor for details. For the best PS VR experience on PS5 we recommend using a DUALSHOCK®4 wireless controller. Selected games may require PlayStation®Move motion controllers or be compatible with the PlayStation®VR aim controller. The new HD camera for PS5 is not compatible with PS VR. The PS VR headset, PS Camera, DUALSHOCK 4 wireless controller, PS Move controllers and PS VR aim controller are all sold separately from PS5.
