Early PA-RISC Systems 822, 832, 842 and 852: Low-Cost NS-2 and PCX

4.2.5 822, 832, 842 and 852: Low-Cost NS-2 and PCX

Shortly after, in 1989, lower-end and more compact servers were introduced, apparently also based on

the NS-2 and PCX processors but already using the HP-PB I/O bus: (See Note 7)

HP 9000/822 SilverFox Low:

 25MHz NS-2 processor

 32KB cache (separate I/D)

 4096-entry TLB

 Maximum RAM of 128MB (some sources say 64MB)

 Performance of about 10 MIPS

 Price of about US $20,000 at time of introduction

HP 9000/832 SilverFox High:

 30MHz NS-2 processor

 128KB cache (separate I/D)

 4096-entry TLB

 Maximum RAM of 128MB (some sources say 64MB)

 Performance of about 15 MIPS

 Price of about US $30,000 at time of introduction

HP 9000/842 SilverBullet Low:

 32MHz PCX processor

 1024KB cache (separate I/D)

 8192-entry TLB

 Performance of about 30 MIPS

HP 9000/852 SilverBullet High:

 50MHz PCX processor

 1024KB cache (separate I/D)

 8192-entry TLB

 Performance of about 50 MIPS

These 8x2 servers were described as all having CMOS PCX processors in previous versions of this page.

This is apparently not correct, as the 822/832 HP brochures state that these systems had NMOS CPUs,

with the system block diagrams pointing to a NS-2. The picture for these systems is not really clear,

with available benchmark results pointing in an even different direction.

4.2.6 Benchmarks

Assorted MIPS “benchmark” numbers for systems with known, unambigious results, in ascending or-

der.
