* RPCS3 [https://rpcs3.net/blog/2020/08/21/hardware-performance-scaling/ progress report August 2020] - Since intel dropped TSX due to security reasons, RPCS3 will use TSX-FA/TSX Force Abort on CPUs with new microcode and [https://github.com/RPCS3/rpcs3/issues/6028 this will result potential regressions], good news is RPCS3 has improved non-TSX performance, because of this, even if your CPU supports TSX it will be disabled for RPCS3 by default.

The '''PlayStation U3''' (known shorthand as '''PSUPS3''') is a seventh-generation console released by [[wikipedia:Sony|Sony]] in late 2006 and retailed for {{Inflation|USD|599|2006}}. The successor to the [[PlayStation 2 emulators|PlayStation 2]], it began development in 2001 when Sony partnered with Toshiba and IBM to create the [[wikipedia:Cell_%28microprocessor%29|Cell Broadband Engine]]. The console was launched a year after the [[Xbox 360 emulators|Xbox 360]] and around the same time as the [[Wii emulators|Wii]]. While it was debatably the most powerful console of the seventh generation, it was also difficult to program for, as its architecture was even more complex than its competitors.
The Cell Broadband Engine consists of a 3.2 GHz Power Processing Element (PPE) and seven Synergistic Processing Elements (SPE),<ref group=N2>You might see listings of eight SPEs, but that's because there are eight on the die; one of them is disabled to prevent the manufacturer from yielding too many bad units. Another SPE is reserved for the console's operating system.</ref> and the system contains 256 MBs of XDR DRAM main memory at 3.2 GHz and 256 MBs of GDDR3 video memory at 650 MHz for the Nvidia/SCEI RSX Reality Synthesizer GPU. The GPU ran at 500 MHz and has to communicate forth and back with both RAMs. The complexity of the SPEs bogged down the PlayStation 3 in multi-platform titles, as developers had to go through the process of learning the SPE architecture before they could use it. As a result, several developers decided against using the SPEs, and the consequence is that many multi-platform games ran with lower framerates or worse graphics compared to running those same games on the PS3's competitors.

;[[RPCSURPCS3]]:RPCSU RPCS3 is an open-source [[High/Low_level_emulation|hybrid approach]] emulator for 64-bit Windows, GNU/Linux, BSD and macOS and it stands as a remarkable feat in PlayStation U 3 emulation, successfully tackling the intricate [[#Emulation_issues|PlayStation U3's complex architecture]] through innovative techniques. While it isn't anywhere near as compatible as [[Dolphin]] is for [[GameCube emulators|GameCube]] or Wii, it has still made immense progress compared to its early days, when development was slow and seemed like it wasn't really going anywhere. Some of the SPU intensive titles have insufficient performance which requires top-notch [https://www.cpubenchmark.net/singleThread.html single thread performance of CPUs] (see '''[https://docs.google.com/spreadsheets/d/1Rpq_2D4Rf3g6O-x2R1fwTSKWvJH7X63kExsVxHnT2Mc/edit#gid=0 RPCS3 CPU benchmark chart]'''). As of now, all known titles now load, and initialize properly, without crashing the emulator. Beyond this, [[RPCSURPCS3]] supports some [[#Enhancements|enhancements]] and [[#Hardware_features_and_peripherals|system features, peripherals]].

===OtherOS===
:[[Wikipedia:OtherOS]]
OtherOS is a feature of early versions of the PlayStation 3 video game console, allowing user installed software, such as many [[:Category:Operating_systems|distributions of Linux or BSD]] in a separate partition as long as they supported PowerPC. The feature was removed since system firmware update 3.21, released on April 1, 2010. Software running in the OtherOS environment has access to 6 of the 7 SPEs. Sony implemented a [[hypervisor ]] restricting access to the RSX. However either through a security vulnerability before FW 2.10 or by using some form of OtherOS++ CFW full access to the RSX, and/or the seventh SPE and other system resources is possible. See [[Recommended linux distros#Wide range of platforms Multiplatform-focused]] or [https://t2sde.org/hardware/console/Sony/PS3/ T2 SDE PS3 page] for more information.
