- I'm sure others will post the press releases and so forth, but I'd
- like to highlight the features that (IMHO) make each of the products
- interesting. Some of this is from memory, so for final numbers,
- wait for the data sheets from your salescritter (hedge, hedge :-).
-
- Indigo^2 Extreme
- new chassis: EISA slots, GIO-64 bus (266Mb/sec), more audio,
- upgradeable CPU: currently available in
- 100 Mhz R4000 (same as Indigo), and 150Mhz
- R4400 in CYQ3. Fast SCSI-2. different color :-).
- new Extreme graphics: basically 2x the Elan geometry performance
- I think 630k tmesh/sec is what we quote.
-
- XZ graphics - 2x of the XS/XS24 performance. I believe this
- will be available in both Indigo and Indigo^2.
-
- Challenge Server ("M"):
- The Indigo^2 CPU/chassis in a server configuration
-
- new MP machines:
-
- They share the same bus, same IO, and same memory boards.
- The backplane varies in what qty of each can be installed,
- and some backplanes have no slots for graphics. The chassis
- are either deskside, rack w/gfx, and rack w/o gfx.
-
- Up to 9 processor boards:
- 100Mhz R4400 this quarter
- 150Mhz R4400 in CYQ2/CYQ3
- upgradeable beyond that.
- 4 processors per board ==> 36 processors max.
-
- up to 16 GB of memory using multiple boards
- (1,2,4, or 8way interleave)
-
- up to 4 IO boards
- 320 Mbyte/sec I/O bus each
- up to 8 device slots/board
- up to 32 SCSI-2 (fast 'n wide) channels
- 20Mbytes/sec/SCSI-2 channel
- VME64: 50Mb/sec, up to 5 buses, 24 slots
-
- the backplane bus bandwidth is 1.2Gbytes/sec
- 40 bit wide physical address
-
-
- The Products:
- Challenge Servers (desk side ("L") & rack ("XL"))
- support up 9 processor boards (36 R4400s)
- Don't have a graphics bus
-
- Onyx rack
- support up 6 processor boards (24 R4400s)
- up to 3 graphics heads
- either VTX or RealityEngine^2 graphics
-
- Onyx deskside
- 1 processor board (up to 4 R4400s)
- 1 graphics head
- either VTX or RealityEngine^2 graphics
- 2 100Mhz R4400 processor, 64Mb, 2G, VTX: $114,900
- 2 100Mhz R4400 processor, 64Mb, 2G, RealityEngine^2: $155,000(?)
-
-
- RealityEngine^2 graphics
- similar to RealityEngine, but with 12 instead of
- 8 GeometryEngine processors (i860XP). For most
- geometry, ~50% faster than existing Crimson RealityEngine.
-
- Supports up to four Raster Managers.
-
- Because of the increased host bus bandwidth, pixel
- operations and texture loading will increase
- significantly.
-
- ~1.5M tmeshes/sec flat
- ~900k tmeshes/sec textured && AA
- ~20Mpix/sec 32bit lrectwrite
- ~25Mpix/sec 32bit lrectread
-
- VTX graphics
- similar to RealityEngine, but with 6 instead of
- 8 GeometryEngine processors (i860XP). Can only
- support 1 Raster Manager, so multi-sample AA
- available at reduced screen resolution (960x680).
-
- ~1.0M tmeshes/sec flat
- ~450k tmeshes/sec textured && AA
- >15Mpix/sec 32bit lrectwrite
- >15Mpix/sec 32bit lrectread
-
-
-
- Also announced was the Power Challenge Server. The only difference
- (but its a _big_ one) is that it supports up to 18 TFP processors (2 per
- board).
-
- The TFP processor is a MIPS compatible CPU with very hot floating
- point performance. It will be available in CYQ1 of 1994 but
- was announced now to give supercomputer purchasers the lead
- time to actually order one and to make it clear that the
- Challenge series will be upgradeable in multiple directions.
- The quoted performance is 300 MFLOPS _peak_ per processor for
- a total performance peak of 5.4GFLOPS for a fully decked
- 18 processor server.
