;[[Xenia]]
:Xenia is the leading [[High/Low_level_emulation|hybrid approach]] Xbox 360 emulator that's made it the furthest. While it isn't nearly as compatible as RPCS3 is for [[PlayStation_3_emulators|PlayStation 3]], impressive performance outshines RPCS3 due to RPCS3's [[PlayStation_3_emulators#Emulation_issues|extremely challenging SPU emulation]] resulting reasonably higher CPU demands. Another reason for performance difference is Xenia utilizes [[High/Low_level_emulation|very high-level emulation (HLE) approach for the CPU, while relying heavily on Low-Level Emulation (LLE) for the GPU]]<ref>[https://discord.com/channels/308194948048486401/308194948048486401/1192362532212576348 Rick's xenia discord message about LLE and HLE]</ref><ref>[https://discord.com/channels/308194948048486401/701111856600711208/1090315143226863616 chrispy's comments about xenia's approach]</ref>. Due to these approaches and other reasons/optimizations (see [[Emulation_accuracy]] page): it's making Xenia more reliant on GPU performance instead of CPU (especially compared to RPCS3). But keep in mind that, it's still depends heavily on CPU single thread performance due to graphics API-related calls and focusing solely '''average''' CPU utilization percentage numbers may give you false impression[https://discord.com/channels/308194948048486401/308194948048486401/1199060658059235479]. So in summary: just like most other software emulators, CPU's with better [https://www.cpubenchmark.net/singleThread.html single threaded performance] will give you better framerates than before (considering you're not hitting GPU bottleneck)[https://discord.com/channels/308194948048486401/308194948048486401/518932236746096640]. Xenia supports various [[#Enhancements|enhancements]] and some of the [[#Hardware_features_and_peripherals|hardware features]]. For emulation on Linux: see [[Xenia#Linux_and_SteamOS.2FSteam_Deck|this page]].
::'''canary''' builds compared to the master builds offer improved performance (thanks to chris, disjtqz, gliniakGliniak, AdrianCassar and [https://github.com/xenia-canary/xenia-canary/graphs/contributors other contributors]), it has experimental changes that may or may not work, but it also has more functions/tends to work better. Also some of the [[#Hardware_features_and_peripherals|hardware features]] and [[#Enhancements|enhancements]] are currently only available in this fork and its branches mentioned below. Use [https://github.com/xenia-canary/game-patches this repository] for game-patches which some of them may fix graphical or performance issues.
::'''canary-netplay'''; see [[Xbox_Live#Xbox_360|Xbox Live]] page (Xbox 360 section).
::'''canary-nukernel''' branch emulates: The [[#Emulation_issues|six individual hardware threads on the original Xbox 360 CPU]], certain kernel timing quirks (clock interrupt update every 1millisecond, "background scheduling"), the kernel's thread scheduler, deferred procedure calls, asynchronous procedure calls (done more accurately than on normal canary, plus kernel ones are supported), much more accurate and portable emulation of synchronization primitives, supports guest objects without creating host objects for them. So certain games that do not work on normal canary can be played on this branch, because the features/quirks they expect are implemented here, but nukernel branch mostly focuses on reimplementing parts of the threading subsystem of the kernel, not io or memory, which are also messed up. Developer of this branch said that: "It really felt like starting from scratch on the kernel side, because for a long time nothing booted on it".[https://discord.com/channels/308194948048486401/701111856600711208/1200116567489384548]
