Alan is absolutely right, take a look at http://www.aslab.com/contents/workstations/Marquis-C250S.html. Aslab is selling the Marquis C250S with the Tyan Thunder 2500 board (ServerWorks HE chipset) + linux preinstalled now in quantity. I ordered one dual PIII system with the Tyan Thunder 2500 board last week and will report my experiences as soon as possible. One really bad point of these boards is that they need slot 1 PIII which are becoming rare and rare. So blame on Intel which is not able to ship really perfomant chipsets for their prozessors! The i820 and also the i840 chipsets are also with Rambus RD800 modules not very well performing. I've run the stream_d benchmark on an i840 system (1GByte RD800, two PIII 800 MHz) with a vektor leght n of 9912111 and got a mesured memory bandwith for triads of only 585 MBytes/s. I have checked all Bios values and they seemed to be correct. So take a look at the price of this system (~ 15000 US $) and compare this to the memory bandwith of the old BX chipset (~ 400 MByte/s for triads). For the people who are interested in the measurement in more detail: The stream source was compiled with the Portland Group FORTRAN 77 compiler, using the following flags: -fast -tp p6 -Mvect=sse -Mcache_align -Munroll -Minline Mvect=sse tells the compiler to turn on the SSE feature if possible (not used here, because stream_d uses double precision veriables!). I only mention it to avoid questions in this direction etc. So this flag can also be left out in this case and has no influence on the performance numbers (I have tested this!).
