The 20 stages were counted from the trace cache. 21 stages might make you think that the 970FX is close to a Pentium 4 Northwood, but you should remember that the Pentium 4 also had 8 stages in front of the trace cache. Floating point is handled through 21 stages, and the Opteron only needs 17. While the Opteron has a 12 stage pipeline for integer calculations, the 970FX goes deeper and ends up with 16 stages. The 970FX is deeply pipelined, quite a bit deeper than the Athlon 64 or Opteron. Remember that most of the performance boost (10-30%) noticed in x86 64 bit programs came from the 8 extra registers available in "pure" 64 bit mode. Insiders say that the PowerPC970FX has less "register pressure" than, for example, the EM64T and AMD64 CPUs (16 registers), which on their turn have less register pressure than the "older" 32 bit x86 CPUs with only 8 architectural registers. The end result is better performance, thanks to less "bookkeeping". These are the registers that can be used to program the calculations in the binary (and assembler) code.Ĭompilers for the PowerPC 970FX should thus be able to produce code that is cleaner, with less shuffling of data between the L1-cache, "secret" rename registers and architectural registers. Architectural registers are the registers that are visible to the programmer, mostly the compiler programmer. The RISC ISA, which is quite complex and can hardly be called "Reduced" (The R of RISC), provides 32 architectural registers. The fastjump navigation is cool, but the keyboard layout is azerty in xbench which switches keys ( q-a and z-w) if you're using a qwerty keyboard.Meet the G5 processor, which is in fact IBM's PowerPC 970FX processor. MegaRam switch added as a Launcher global option. Music switch added as a Launchers global option (Switch On/Off). AutoVec switch added as a whdload global option. MMU switch added as a whdload global option. Cache switch added as a whdload global option. Display switch added as a whdload global option (Switch PAL/NTSC). Preload switch added as a whdload global option. Sometime the setup exit on a black screen. Fixed a small palette bug when leaving the setup. No more create a bugged list when there's nothing to add to the list in the choosed path. Now display the number of files added to a listing when updating in the setup. Now ending a path with a "/" in the setup will work as same as without. Now listings are of real unlimited size. Now the listings are 3 time lighters than with the previous release. Now the subdirectorys level scan is unlimited. Really useful to clean up a buggy install of X-bEnCh. Added the "resetxset" command to the cLi. ![]() Added the "help" command to the cLi to list all the extra X-bEnCh cLi commands availables. Now the game name in the loading screen is truncated and centered. Now in the launcher, a short push on the 2nd joy button will switch between your listings and a long push will escape to the main menu. Now display the number of files in the listing, right to the listing name in the launcher. If none found, use the default tooltypes you've set in the setup screen. Now autoscan the tool types of WhdLoad. Now return where you was before, after leaving a game. Now simply use your keyboard's key to jump where you want. Launcher Reactivity optimisations and lighter code. Now working with a temp dir to leave the Ram free. ![]() Now display the release number under the X-bEnCh startup logo. Now pressing the "Del" Key when startup will cancel the X-bEnCh loading. Fixed some files check on startup that were wrongs. You can stay in touch with me via twitter: can "Like" the xbench facebook page: All yours returns are welcomed The current release available is the 1.1 Final Public Release. Many more will come in the nexts releases. Dedicated installer for an easy installation Integrated cLi 100% Amiga cli compatible CDMode to create your CD32/CDTV CD compilation. ![]() FastJump mode to jump where you want in a list with the keyboard MegaRam mode to gain extra chipram without rebooting If no Tooltypes availables you can set up default Tooltypes. Up to 640 colors on screen with AGA (128 colors on screen for OCS/ECS) X-bEnCh also have an integrated CLI fully compatible with the Workbench CLI features and a Files/Dirs Manager (X-pl0rEr). It require very few ressouces and is compatible with all Amiga setups. X-bEnCh can also manage manuals listings and have an internal script system, the X-bEnCh Scripts (For non whdload games for exemple). exe and organize them in launching listings. With 640 colors on screen with AGA (128 with OCS/ECS), this Frontend can autoscan your hard-drive to find all your whdload games or your. X-bEnCh is an Amiga game launcher & More …
