I have an ATW800, so I might somewhat clarify the situation:

Price (count #1 = DM2.7) DM 14500 + Tax. (Dec 89)
Specs: 1 T800-20MHz (4MByte-70ns), 1 MC68000 (1MB Atari ST with all ports);
       1 Videoboard (1MByte, 1260x960-4bit, 1024x768-8bit, 512^2-24bit,
                     Graphics proc. with peak-rate of 128 MPxl/s);
       40MB SCSI drive, prepared for 2nd one, MS-DOS 720KByte 3'5 floppy.
       Helios Netversion (without C compiler).
       X-Windows v11.2 (only server and most important xclients.
        this version does not seem to use the graphic proc., performance below)
Add On's: 8 to 24 MByte main-mem with 1Mbit DRams, up to 3 farmcards
       (a 4 T800-20 with 1MB each) in box.
       (Ethernet TCP/IP and Berkeley filesystem announced for spring)
Software: all Helios (compiler [C,Pascal,f77,..], C-de*, par-C, TDS,
       TeX. Graphics packages, Ray-Trace, flight sim., neural nets ...
       in progress).
Performance:
       Dhrystone: 2500 (bad!). with Helios `Accelerate`=4000.
                  completely on-chip I expect 6000. [Perihelion C v1.1]
       Floats:    0.3 - 1.7 MFlops, depending on compiler etc.
                  (for f77 there is an optimizing pre-processor.)
       X-Windows: I hereby publish my X-Bench results of Dec89:

  I do not believe that the current server has much blitter support.
  => big improvements awaited...

(I do not have any relationship with Atari, I just bought an ATW.)

Summary:
  I am quite satisfied with my machine, provided that all the minor
  problems will be solved in the near future, i.e.
   a serious file-system, more tools, Ethernet support (TCP/IP, NFS),
  improvement of X-Window scrolling speed and cheaper farmcards.
  Helios, of course does have good network facilities to other
  Helios nodes via link. But still there are machines without any link..
  The ATW addresses to the workstation market rather than the number-
  cruncher card market.  A single transputer ATW is slightly outperformed
  by the DecStation 2100 at the same price, but it has much more chances
  not to be outdated in 3 years.
