INTEL PENTIUM ANNOUNCEMENT AND ANALYSIS On March 22, 1993 Intel formally announced the Pentium (P5) micro- processor, the latest member of Intel's x86 family. Intel will announce Pentium chip pricing in May or June. Other vendors made related announcements of support for Pentium; system announcements and system availability are expected in May. HP announced that its new line of PC servers will support the Pentium microprocessor; an HP announcement of file and application servers is planned for May. THE ANNOUNCEMENT Pentium Features: - 273-pins in a 21 x 21 4-row pin grid array - 3.1 million transistors - 60- and 66-MHz clock speeds - 64-bit data bus - 32-bit address bus - a superscalar implementation and two five-stage execution units enable Pentium to process two simple instructions simultaneously - two 8K on-chip caches - a floating-point unit - branch prediction that enables the chip to recall prior instruction pathways and predict the correct pathway for a new instruction. - runs at 5 volts Pentium chips are fabricated in a 0.8-micron, 3-layer metal BiCMOS process. Software that runs on a 486 should run without problems on a Pentium.

With vastly improved floating-point performance over the 486, Intel is looking to attract technical users of engineering, CAD/CAM, client/server, financial analysis and modeling, multimedia (full-motion video, voice recognition and imaging), and other emerging high-end applications that require very fast floating-point processing. Intel's Future Plans -------------------- Intel's announcement indicated that: - 486DX2-based systems will be upgradable to Pentium in the future - An OverDrive processor that disables the original processor and increases system performance will be available in 1994.

Intel expects to ship its one-millionth Pentium sometime in 1994. THE ANALYSIS Intel's press release on Pentium was brief and limited. Additional information, which included interviews with Intel sources and PC vendors, was available through industry consultant reports and trade press. That information is reflected in this analysis. Announcement Strengths ---------------------- * Performance Improvements over the 486 * Pentium provides substantially improved integer and floating-point performance compared with the 486. * Excellent Price/Performance on the Desktop * Pentium-based desktop systems are expected to be priced in the $4,000 to $10,000 range, with an average price of $6000; servers are expected to be priced above $10,000. At this pricing, Pentium-based systems deliver excellent price/performance on the desktop. * First Superscalar Implementation for PC systems * Pentium's superscalar implementation is a first for PC-class systems; with it, Pentium decodes two simple instructions simultaneously. * Excellent Integer Performance * Pentium's substantially improved integer performance should allow Intel to maintain its market position on the desktop. Pentium's integer performance is within range of all its RISC competitors. Its integer performance at 50-MHz is 31% better than a 50-MHz PA7100 and twice that of a 33-MHz PA7100. HP Selling Points ----------------- * Pentium Performance Limitations - Software Recompiles Required * - Significant performance improvements can only be obtained by code optimization and recompilation using special Pentium compilers. In some cases code must be rewritten to improve performance; code must be redesigned to take advantage of the 64-bit data bus. - Actual performance is affected by system implementation, so performance of different vendors Pentium-based systems will vary. - Code that has been recompiled for a Pentium will run on a 486 with little or no affect on performance. *HP's Superior Floating-Point Performance * At 50-MHz, PA7100 floating point performance is 65% better, and at 33-MHz, PA7100 floating-point performance is 6% better than the estimated 50-MHz Pentium performance. Many PC vendors have said they will run the Pentium at 50- to 55-MHz due to heat dissipation problems that result when running the 3.1 million transistor Pentium at 66-MHz. Intel wants to target multimedia, engineering, CAD/CAM and other applications that require very fast floating point. While Intel has made great improvements over the 486, they haven't delivered floating- point performance superior to their RISC competitors, and Pentium doesn't come close to the 50-MHz PA7100 in floating-point performance. We should compete on our floating-point performance, not on price/performance. * Pentium Chip and System UNAvailability * - Currently, due to heat problems, the 5V Pentium cannot run reliably at 66-MHz. It is believed that Intel is working on a 3.3V version to resolve this problem. Reliable Pentium systems that can run at full clock speed won't be available until CQ194. - The supply of Pentium chips will be limited in 1993 due to 1) High Price: Intel expects to announce Pentium pricing in May or June 1993. Speculation is that Pentium chips will initially be priced at around $950, though a range of $800 to $1000 has been noted. 486 chips are currently priced at $300. 2) Limitations in production speed: Intel spent $2-3 billion on R&D and plant capacity for Pentium, compared with $1 billion total on the 486. They can currently produce a dozen 486 chips for every one Pentium. With Pentium costs and pricing so high, Intel must continue to sell 486s to maximize profit. 3) Limited Pentium distribution and push on 486 sales: Intel plans to ship about 10,000 Pentiums in CQ293, with volume shipments coming as 486 sales slack off. They are content to sell primarily 486s and expect to sell 25 million 486 chips in 1993. A limited number of Pentium samples are now available to first-tier Intel vendors. All vendors anticipate a short supply of Pentium throughout 1993; first-tier vendors expect only 1,000 to 4,000 chips per month, compared with about 50,000 486 chips per month each. Some vendors don't expect to receive ANY Pentium chips until CQ393. - PC and chip vendors have indicated that they need extra design time to design their Pentium products because of the chip's complexity and because of heat problems at 5V. - Currently available supporting chips (for example, logic chips) that must work with Pentium are slow; only a limited number have been tuned to work with it, so early systems based on Pentium may not be able to exploit the chip's full capabilities. * UNavailability of Technical Applications for Pentium * Though Intel is working with software developers to encourage shipment of products that take advantage of Pentium, only two dozen applications tuned for Pentium are now available; Windows and Windows NT are not among them. Existing applications will run and will provide some speed gains but won't take full advantage of the chip. To maximize improvements applications must be recompiled and, in some cases, rewritten. Currently HP has over 5,000 applications available for PA-RISC, over 3,200 of those for the Series 700 family. As workstations have always been a powerhouse for technical applications, a significant number of these are technical floating-point intensive applications. Today there are a limited number of technical floating-point applications for PCs; these must first now be developed. HP is experienced in technical applications, and we have a large installed base successfully deploying and using technical floating- point intensive applications on PA-RISC. * Hidden Costs of Pentium and PC ownership * Hidden costs associated with purchasing a Pentium-based system include new compilers, new versions of applications tuned for Pentium, and the hardware upgrades required to eliminate heat dissipation problems and take full advantage of Pentium's potential performance. In addition, recent research by Nolan, Norton & Co., a Boston-based consulting group, shows that the actual cost of PC ownership, because of support costs ranging from $6,000 to $15,000 annually per PC, is significantly more than the total budgeted amount--usually 2,000 to $6,500 annually per PC--for its purchase, network, and support. * Limitation of Pentium's Superscalar Implementation * The key to Intel's superscalar implementation is that the instructions must be "simple". In other words, Pentium can only decode two integer instructions simultaneously. The PA-RISC 7100 superscalar implementation can decode one integer and one floating point instruction simultaneously. * Pentium Clone Availability * Pentium clones from AMD and Cyrix are expected within 9 to 24 months. This is much sooner than any intel-clone manufacturers have shipped their products in the past. Clone availability will come right on the heels of Intel's general availability and could impact Intel's sales more than ever before. * OS Deficiency on Pentium * NT, the primary OS target for Pentium, has not been Pentium-optimized or recompiled. Furthermore, even once it is available, NT will be a new operating environment on a new architecture. There are bound to be some problems in this environment. HP-UX is a mature, robust, proven operating environment with the functionality required in a day-to-day working environment and the support for technical applications. SUMMARY Intel has made some great improvements over their 486 chip. But Intel has far to go before impacting their RISC competitors due to Pentium's - performance limitations and the need to recompile software - inadequate floating-point performance for technical applications - chip UNavailability throughout 1993 According to a Gartner Group analysis, "trends in performance of the RISC processors indicate that Pentium will lag all architectures by the time it ships in volume". HP is the leader in RISC. Intel's Pentium should have little impact on our success in the workstation market.
