PA6T promises much better speed than 8640D/8610 (two times faster - in sense Y=2*X - in integer operations.

That's not true even in theory. The e600 has 4 Integer units, the PA6T has 2, and they take 2 cycles.

I suspect on integer workloads (a *lot* of Amiga stuff) they will be quite close.
On high throughput stuff the PA6T should be better.

that only for the schematics. X1000 have go until producction run stage

The £200K on the X1000 appears to be on development only. It'll cost well over £100K to do the production run.

The 8610 board would have cost a lot less.

PASemi promised 1000 SpecInt2000 and 1500 SpecFp2000 performance. I don´t know, if these numbers are true (we don´t have enough benchmarks), but that would be much faster than at least G4.

@pavlor

Apple aren't real forthcoming about sprcs in general not just this chip

About 8640D/8610...

Could someone provide a link to 8640D/8610 spec values for my lazy bones?

There are no SPEC CPU values for these CPUs. However, There are some benchmarks on the EEMBC page:

Automotive benchmark (multiple FPU benchmarks - eg. Inverse Fast Fourier Transform):
Freescale PowerPC 603e 300 MHz - 196.2
AMCC PPC440EP 667 MHz - 575.0
IBM 750GX 1000 MHz - 1155.8
Freescale MPC7447A 1400 MHz - 1564.1
Freescale MPC8641D 1500 MHz - 1612.7
IBM 970FX 2000 MHz - 2108.7 (32 bit mode)

Consumer benchmark (JPEG compression/decompression, High Pass Grayscale image filter, RGB to CMYK Conversion, RGB to YIQ Conversion):
Freescale PowerPC 603e 300 MHz - 21.5
AMCC PPC440EP 667 MHz - 60.6
IBM 750GX 1000 MHz - 124.0
Freescale MPC7447A 1400 MHz - 197.2
Freescale MPC8641D 1500 MHz - 221.4
IBM 970FX 2000 MHz - 284.5 (32 bit mode)

Digital Entertainment (MPEG encode/decode, JPEG compression/decompression, etc.):
IBM 750GX 1000 MHz - 173.6
Freescale MPC7447A 1400 MHz - 257.6 (537.8 - Optimized with AltiVec(tm) technology)
Freescale MPC8641D 1500 MHz - 315.0 (713.9 - Optimized with AltiVec(tm) technology)
IBM 970FX 2000 MHz - 385.4 (32 bit mode)

See www.eembc.org for more details.

@pavlor



UPDATE: I wonder why Acube use 460ex instead of MPC8610...
Because they have better connections to AMCC than to freescale?

@anyone

Does anyone have the information of how much it cost to have a custom chip to be designed&manufactured?

For example some PPC + 2D+3D chip on a SoC. (or PPC + 2D+3D + xcore for I/O)

I imagine that before long we have such (powerfull enough) SoCs (at least ARM and x86) that could be used to replace pretty much the whole traditional motherboard.
That kind of chips would be ideal for small niches like Amiga.

@pavlor
The X1000 uses an Apple made chip, Apple are not know for releasing data about their chips. Look at he well they maintained the PPC superiority myth......

@persia

What do u mean ppc superioty myth.........its still going, hehehehe.

oh no, wait, does that mean its not a myth then?

haha, well, i think arm is doing very well, look at the iPhone.

cheers

It must have been the Amiga-curse.

Hi everyone, hehe, it's interesting to read in a forum that people are thinking of contracting me. Disclaimer: I'm the guy behind freevec.org, aka markos, and I was a long time Amiga user as well (had A500/A500+/A4000+060, etc) until 1997. But I'm still very fond of my first computer and read some Amiga forums from time to time -and I would seriously consider buying a new X1000 if the price was lower.

Im not registered on Amigans, but someone should point out to him that AOS4 is workable under emulation now

Someone already has posted that info, but does AmigaOS4.x really run at an acceptable speed via emulation?

I have not tried it myself and have only casually been reading some of the threads about it, so I don't really know what is possible with Toni's latest work on UAE.

@amigadave

Speed is acceptable (if you don´t need FPU or faster GFX/compositing). I estimate performance of 400-1000 MHz G3 (benchmark dependend) on my Core i5-2500K 3.3 GHz. Memory limitation (128 MB Fast RAM and 4 MB GFX RAM) is the weakest point.

Eg.:
Doom, Hexen, Heretic - work in 640x480 60 FPS
Quake, Hexen II - work in 320x256 25 FPS
RunInUAE is able to emulate most OCS games (but not all - like Lionheart), JIT really helps in AGA emulation (playable but not perfect on my hardware).
DosBox works - performance comparable to 2000 CPU cycles (eg. 386SX-16 MHz).
Wargus (Warcraft 2), DuneLegacy - work good in 640x480.

Odyssey is useable, but requires too much RAM. My main browsers are IBrowse (downloading from OS4depot and Aminet) and Netsurf (Wikis).

AbiWord is useable, more RAM is needed for bigger documents.

Speed of QT applications (like qpdfview) is good, but these are also memory hungry.
