The AViiON 4600 comes in low-cost deskside packaging and starts at new $20,000 with 32Mb memory, 332Mb disk and 525Mb QIC tape, using a 33MHz Motorola 88100 processor to deliver 39 to 78 MIPS.The AViiON 4600 running Informix-OnLine 4.0 is claimed to delivers TPC-B throughput of up to 58tps-B at $2,450 per transaction per second. It is available in 45 days. The AViiON 530 workstation does up to 78 MIPS and has an improved input-output subsystem and graphics and is from $13,500 with 16Mb memory and 32Kb cache, with graphics options such as 8- or 24-bit graphics and a 24-bit Z-buffer. It is available later this quarter. Price on the entry-level 4100 server plunges to $10,000 from $21,390 with 16Mb memory, 332Mb of disk and 150Mb QIC tape. 5225/6225 servers are from $43,500 with 64Mb CPU, 1Gb SCSI disk and a 525Mb QIC tape, and support up to 414 AIM II users, and are claimed to perform 35% better than IBM Corp’s high-end Powerserver 550.
