i make a test with my kernel with full fpu emulation on cyrus .
this are the emulated instruction 57 -rw-r--r-- 1 0 0 Jan 1 1970 lq_stq 56 -rw-r--r-- 1 0 0 Jan 1 1970 mtdscr 55 -rw-r--r-- 1 0 0 Jan 1 1970 mfdscr 54 -rw-r--r-- 1 0 0 Jan 1 1970 math 53 -rw-r--r-- 1 0 0 Jan 1 1970 unaligned 52 -rw-r--r-- 1 0 0 Jan 1 1970 sync 51 -rw-r--r-- 1 0 0 Jan 1 1970 string 50 -rw-r--r-- 1 0 0 Jan 1 1970 spe 49 -rw-r--r-- 1 0 0 Jan 1 1970 popcntb 48 -rw-r--r-- 1 0 0 Jan 1 1970 multiple 47 -rw-r--r-- 1 0 0 Jan 1 1970 mfpvr 46 -rw-r--r-- 1 0 0 Jan 1 1970 mcrxr 45 -rw-r--r-- 1 0 0 Jan 1 1970 isel 44 -rw-r--r-- 1 0 0 Jan 1 1970 fp_pair 43 -rw-r--r-- 1 0 0 Jan 1 1970 dcbz 42 -rw-r--r-- 1 0 0 Jan 1 1970 dcba 41 -rw-r--r-- 1 0 0 Jan 1 1970 altivec 40 -rw-r--r-- 1 0 0 Jan 1 1970 do_warn
only string and mfpvr look like really emulated
mfpvr 2811 string 124809844
... result quake spasm differ with only 20fps less than the kenrel without emulated instruction...
i hope this will help stop some speak about performances on tabor

He already had an OS4 machine, and he upgraded to an X5000. I thought we were talking about Tabor here. I must be missing something. _________________ This is just like television, only you can see much further. |

Dont worry Luigi.
The whole Tabor bashing started because of this post. http://www.amiga.org/forums/showpost.php?p=797215&postcount=12 To cover up the fact that he pretends to have knowledge when he doesn't he then started to bash the same board that he claimed to have facts about in his initial post.

Your original statement about market saturation implied to me that you think tha nobody wants/needs any new AmigaOS hardware of any model .

| @Spectre660 I said the market is mostly saturated. I don't know how that could be interpreted as "nobody needs/wants new hardware". The X5000 is an upgrade to a Peg2 in terms of performance, while the Tabor would be a downgrade.

What, I get credit for being the first to realize what a weak piece of crap this is?
Well, in all modesty, that is not exactly correct.
As to information, I was misinformed by a friend who was shown this board when it was first announced (leading me to believe it had a better CPU).
Since then, I have had a chance to exchange messages with a few people that actually have these boards, and THAT is what my current opinion is based on.
If YOU want to buy new hardware that is slower than many Athlon XP systems, do it.
But you won't be able to point to me as the one advocating the idea.
I have never replaced hardware with something that performed worse.

sorry but i dont think my old peggy was able to have a pcie new gen video board and 1333mhz ddr3 ram and cant play 1080p videos ... for sure this on linux because the tabor dual cores... amiga os one core is a boottle neck for a power8 cpu too. with only one core i cant able to play 1080p video on quad g5 or on p5020 too... only 720p can perform max there on one core. if only the full hw accelerations in video decoding probably we can raise the video play on one core on amigaos
video decoding is one example... same is browsing and gaming.. Last edited by tlosm on 28-Mar-2016 at 04:43 PM. Last edited by tlosm on 28-Mar-2016 at 04:39 PM.

If you don't like the published specs then fine. Just say that the spec and your expected performance levels are not high enough for you. You would have expressed your opinion without the perceived negative crusade .
The comparison to Athlon XP is apples and oranges. The concern of people interested in running AmigaOS 4.x is can the hardware run it fast enough and the final price .
The Tabor actually boots Linux faster than virtualbox on the quad core 3.8GHZ machine that I run Linux using 2 cores on. There are times when some processes on the quad core machine conflict and I and stuck with a machine that I cant use for minutes. A Sam440ep-flex performed better with AmigaOS 4.1 than this 4 core beast at times like this .

This fully depends on final price, which we don´t know yet... |
700 Euros was the price mentioned in forums back when the news broke. I don't think it was officially communicated though, but I suppose the figure didn't just materialize out of thin air. IMHO the price sounds plausible, and follows AoenKit's pattern of grossly overpriced H/W perfectly...

besides that Linux and 4.X (or MorphOS/AROS or whatever) are different beasts or is 4.X recently supporting SMP?
What do you want to say with your comparations with 3.8 Ghz hardware? That Tabor is faster than a 3.8 Ghz system?
Iggy has shown a potential weakness of the hardware that will propably affect 4.X software because people will not offer special Tabor compiled software. People will look at it when system is really running and software can be tested. You seem you think to have defend Tabor against any critisizm. It is not your design choice or product so you do not have to. |

Honestly just AmigaONs/Pegasos2 was quite outperformed by x86 hardwares around when released, but really not so much than Tabor that was outperformed by quite ever A0migaOS4.x capable hardware around...
And that was st least odd....
That's sad...
And if @TRIPOS price reading of 700EUR was sometimes confirmed, and I REALLY hope that wasnt, thats really a bad... _________________ Simone"Tuxedo"Monsignori, Perugia, ITALY. |

| @tlosm On Linux you can have powerpcspe binaries, use multiple cores, hardware TcL, and so forth. From the perspective of an OS4 user, Tabor is a downgrade. Those next gen video boards are under-utilized even on fast hardware. If you throw in a CPU with slow floating point performance, you won't have a very good experience. _________________ This is just like television, only you can see much further. |

The Tabor CPU isn't PPC compatible, it's as simple as that. Not just missing instructions, but some overlapping instructions as well (i.e. some instructions are there but does something else than on normal PPC).
You would have to spend a year or five to write a PPC JIT compiler to use normal PPC binaries. Then you would have to spend another year or five to write a new Petunia 68k JIT compiler for the Tabor as well. All this just to be able to use OS4 in the way you do it today, i.e. 68k/PPC mixed in the same environment.
And after about a decade, when your monumental JIT work is done, you will end up asking yourself why you didn't do it for x64 or ARM instead of Tabor.
Recompiling the OS/Applications isn't an issue at all in Linux, that whole build process is completely automated, but this isn't even an option if you want to use OS4 the way people do today. And if you go the recompile route, then you would be mad if you didn't drop PPC altogether and aim for a CPU architecture that still has a pulse today... |

Nonesense, Hyperion can simply run Petunia as 680x0 without FPU.
Integer unit is compatible with "normal" PowerPC, only FPU isn´t. |

Your understanding is not quite correct. The identical Linux Ubuntu-Mate 16.04 root partition image boots on Sam460ex,X1000,X5000 and Tabor.(apart from the xorg.conf for the X1000) . Apart from Firefox and video every thing else works on Tabor using the basic linux powerpc fpu emulation.

Maybe not under MacOS, but AFAIK, MorphOS running one of the faster of the already supported G5 machines does 1080p x.264 streams very well (the quad core isn't even supported yet). But I think MorphOS is faster than Mac on this. It plays 720p streams just fine on the faster G4 machines, while this isn't true for MacOS (AFAIK)... |
