1st NeXT Computer 1988: Motorola 68030/25Mhz w/68882 FPU, 64MB RAM max. MIPS: 4
Sun Workstation 1988 Sun-4 line: Spac @ 16-33Mhz, 32-768MB RAM MIPS: 7-114
Now having used both, the desktop and usability on the NeXT was so much better.
You could buy a NeXTstation for $4995 on the open market, and considerably less with an educational discount.
You could buy a Sun Sparcstation 1, which was released a bit earlier and ran a RISC 20 MHz processor but it was $9,000.
If I recall correctly, SGI workstations like the SGI Indigo at the time started at somewhere around $7500 and depending on configuration could be nearly $40k. The SGI Indy, which was the low end SGI machine, was faster and priced at an identical $4995 - but it wasn’t released until mid 1993.
The first Macs to use the 68040 weren’t released until mid 1992. And they also cost $7,000+.
I am unaware of a machine that was available in 1990 for under $5,000 that had more horsepower. If you can point me to one I’ll gladly concede. But at the time I was actually a NeXT campus consultant, which meant I was selling them and knew the specs of both the NeXT products and the major competitors, and I’m not aware of one. Certainly by 1992 the Mac and high end PCs were catching up, albeit both with vastly inferior operating systems.
That was a long time ago and I could well be wrong. But if so I want to see evidence.
I'm pretty sure Sun offered huge academic discounts. I never saw NeXT at any of the local universities... It was mostly Sun and DEC.
But the comparable machines of the time like the Mac IIfx or the Sun boxes of the time had similar or higher prices.
The NeXT hardware was never really competitive in either market except certain niches. E.g., all our clients were in financial trading, because they were willing to pay a huge premium for rapid app development for financial traders.
I looked very seriously at Unix machines around the time NeXT came out, having been converted to that religion in college. NeXT started at around US$6500, and that was with the optical disk only. The equivalent-ish Sun box (Sun 3/80) started at around US$15k with disk as I recall and went up in price really fast if you wanted more memory/disk/etc. About the cost of a new Honda Accord at the time. And the Sparcstations were out at much higher performance (and price...I seem to recall around US$22k for a usable config).
On the other hand, you could get a nicely decked out 386/33 for maybe half the cost of the NeXT, or a 486 for a grand or so more. And it ran tons of software, even if it was garbage. Even Unix.
