Silicon Graphics and MIPS
-------------------------
On November 2 1992 MIPS (now owned by Silicon Graphics) announced new
versions of the MIPS RISC chip.
Key Features
-------------
Full superpipelined 64-bit.
R4400PC - 179 pins supports only an on-chip 16K Instruction/16K Data
cache aimed for low-end desktop and embedded control.
R4400SC - 447 pin with on-board 16KI/16KD caches and capable of
supporting up to 4MB off-chip second level cache. Future SGI Indigo
and Crimson product lines would likely use this chip although
probably only with a 1MB cache. It has 2.3M transisitors.
R4400MC - for multi-processor usage.
All three chips run at either 100MHz, 134MHz or 150MHz (internal) and
are implemented in 0.6micron CMOS and are binary-compatible with the
R3000/R4000. We anticpate that SGI will use only the 150MHz (75MHz
external) chip in future systems. MIPS has increased the clock speed
by 50% and reduced the line width from .8micron to .6 micron, giving
an average performance boost of 1.6 over the R4000 systems. The R4400
has doubled the size of the on-board cache - from 8Kb to 16Kb each
which accounts for the increase in transistor count up from 1.3M on
the R4000.
The chips are fabricated in 2 layer metal CMOS operation at 5V. A
3.3V version is possible with the design but is non-trivial for many
fabrication companies to implement. NEC claim their VR4400 is now
sample shipping ($3300 each) in 3.3V with a 7W consumption.
MIPS Future Plans
-----------------
MIPS indicate that a 100MHz external (200MHz internal) chip is
destined for production in late CY93. In addition, they plan a VRX
integrated, low-cost chip for laptops etc. and a TFP chip with a new
floating point unit implemented on a second chip. This may cause
problems in trying to downsize to smaller desktop computers and will
certainly raise the chip-set cost. However, the TFP would certainly be
able to find a home in SGI's deskside Crimson systems. In 1994 MIPS
expect to release their T5 chip - which they anticpate fighting it out
with Intel as the power engine of choice for running NT.
Performance
-----------
SGI/MIPS now has the following CPU line-up
MPIS MPIS MPIS
R3000 R4000 R4400
(33MHz) (50MHz) (75MHz)
SpecMark89 26 70 113
SPECint89 24 61 96
SPECfp89 28 77 126
MIPS 30 85 136 (estimate)
Price
-----
First pricing shows the R4400SC coming in at $1600 each in
quantities of 1000 from Toshiba and at $1400 from NEC.
Delivery
--------
CPU samples are available now, ramping up of production
is commencing in January with volume shipment due within Q1CY93.
Competitive analysis
--------------------
The R4400 CPU will deliver competitive performance between the level
of a 50MHz and 100MHz PA7100 chip. Generally the MIPS CPU provides
roughly the same performance as the PA7100 at equivalent clock speeds.
MIPS is higher in integer and PA7100 is higher in floating point. This
is the exact opposite of where SGI needs to be - 3D graphics relies
extensively on fast floating point. MIPS has indicated they are
working on a faster floating point unit for a future product.
Here is a possible competitive line-up for typical systems built on
existing and new chips:

Prices and graphics performance numbers are for configured, usable
accelerated-3D systems with 24 planes and Z buffer, 19" color, 500MB
disk (1Gb on 735), and 32Mb RAM. 720 price relfects a promotion price
in effect for this configuration until 12/31/92.
The "e" marks my estimate, other figures are from the MIPS
announcement although they are only PROJECTED performance numbers.
Interestingly, MIPS has not made the SPEC92 projections public.
MIPS indicate that they expect DEC to offer R4400 upgrades to their
workstation line during 1993.
Tactics you can use to win the business
---------------------------------------
SGI will certainly now try to show a clear CPU upgrade path for
the R3000 and R4000 based Indigo and Crimson systems.
But if, because of the high price of the chip, SGI restrict the
R4400 to usage only in the deskside Crimson box HP will in a better
competitive position.
1) - SGI have big margins on their Crimson line, you should
use our expandable 725 desktop line as a lure to get SGI to be
forced to quote their much higher-priced Crimson.
2) - For some deals, the R4400 may make you attempt to respond
with a higher-priced, higher-performance 735 system.
The 735 is not price/competitive with Indigo R4400-based desktop systems.
3) - Any future SGI system based on the R4400 will not be available
until CYQ293.
4) - A 715/50CRX-48Z with 32MB and 500MB disk is $29.5k. This offers
faster graphics performance than SGI's top-of-the-desktop
line Elan super graphics, with comparable CPU performance.
You may find the customer is more interested in graphics speed
than the CPU...
SGI may lead people to assume that upgrades to the R4400 will be
priced the same as the R3000 to R4000 upgrade that they introduced
this year, viz. $5000 for factory-built units and $9000 for a field
board-swap. We already believe their Indigo margins are cut to the
bone and any CPU upgrade may, in fact, turn out to be much higher. Ask
the customer to get written confirmation now of upgrade cost or
factory-built price for the R4400. The cost of each MIPS chip will put
more margin pressure on SGI.
The main point to make to the customer is that HP has superior
graphics performance at every price point up to $50k. If the customer
is evaluating SGI because of their graphics reputation then they
should look at HP as a volume supplier because of the additional
benefits we offer - one year system warranty, international support,
firm financial base, reputation for quality, proven customer
investment protection program, secure in-house chip fabrication
facilities, number one platform of choice for purchasers of
Unigraphics, SDRC and PDA etc. and massive installed base of MCAD
systems.
MIPS has an unusual method of getting the chip to market. The design
is done in-house then released to MIPS-aligned partners for
fabrication - IDT, LSI Logic, NEC, Performance Semiconductor,
Siemens/Nixdorf and Toshiba. Each of these fabricate the chips then
send them back to MIPS for certification. This process is prone to
problems; the R4000 required cross-engineering work by MIPS, the
fabrication facilities and purchasers of the chip resulting in delays
in time to market. In fact the R4000MC has still NOT been certified by
MIPS from any fabrication facility. MIPS has several aligned systems
partners such as SGI, Olivetti, SNI, Acer, Sumitomo, Sony and NEC.
But they have lost key volume partners DEC (in favor of Alpha) and
Compaq (in favor of Intel P5). It may be appropriate to ask your
prospect to inquire from SGI the reasons why.
HP Winning Response - Point 1
-----------------------------
As with the previous R3000 to R4000 announcement, SGI customers can
expect no increased graphics performance in the Indigo or Crimson
systems with any proposed R4400 upgrade. With the new chips, CPU
performance will increase but noticably there is no increase in
graphics speed.
HP Winning Response - Point 2
----------------------------
The PA-7100 has graphics support instructions built in - as CPU's are
upgraded so the customer's graphics will just run faster,
automatically. SGI cannot achieve this as they rely on a hardware
graphics pipeline architecture that is separate to the CPU. They make
their customers pay twice to increase performance - once for a new CPU
and again for faster graphics. For more details on HP's graphics
architecture, see the white paper "The Graphics Architecture
of the 1990's" (part number 5091-5717E).
HP Winning Response - Point 3
-----------------------------
HP beats SGI in 3D graphics performance AND in all other 2D screen
operations in desktop systems.
HP Winning Response - Point 4
-----------------------------
PA-RISC has plenty of room to grow, MIPS have already used many of the
design options open to builders of RISC chips. How far can they carry
on in the 1990's? PA7100 has architecture adjustments already
in-process, even more enhancements to compilers etc., higher-speed
circuits, smaller line width drawing, desktop symmetrical
multiprocessing, newer fabrication techniques. All these will be
implemented as necessary in order to keep the PA7100 the worlds
leading performance microprocessor.
