NexGen Details Sixth Generation Nx686 Processor Technology

  First Nx686 Processor Silicon Demonstration Highlights Industry's Most
  Advanced x86 Processor; Outshines Pentium Pro Up to Two-to-One on Existing
  Applications


     _________________________________________________________________



   MILPITAS, California, October 10, 1995 - NexGen, Inc. (Nasdaq: NXGN)
   today presented details of the technology for its sixth generation x86
   processor family at the 8th Annual Microprocessor Forum in San Jose,
   California. The Nx686 processor, shown running Microsoft Windows on
   first silicon, is designed for the highest levels of performance, yet
   will be targeted for the mainstream, high-volume personal computer
   market.

   "The Nx686 product family is the next step in the Company's commitment
   to leadership in x86 processing solutions," said Vinod Dham, NexGen's
   Chief Operating Officer. "The Nx686 processor builds upon many of the
   technological firsts that NexGen pioneered with its Nx586 processor.
   We are targeting to have this advanced x86 solution in the timeframe
   the Pentium Pro is projected to be available to the mainstream PC
   marketplace."

   Featured as the Forum's "mystery guest", Greg Favor, NexGen's Director
   of Nx686 Processor Development, highlighted some of the processor's
   primary goals. Among these are low cost sixth generation performance
   on both existing 16-bit and new 32-bit code, acceleration of
   multimedia algorithms, low power for portable applications, and
   configurability for cost/performance tradeoffs.

   SUPERIOR PERFORMANCE

   NexGen focused on speeding up both 16-bit and 32-bit "real code" in
   the market. Performance estimates for the processor are up to twice
   the performance on 16-bit applications than those announced for
   Intel's Pentium Pro, and up to 33 percent higher on 32-bit code.

   The Nx686 processor is a single-chip x86-compatible superscalar
   processor with approximately six million transistors. Targeted to be
   initially available at 180MHz, it will be manufactured using IBM
   Microelectronics advanced 0.35, 5 layer metal CMOS production
   process.

   The Nx686 processor builds upon the RISC86 Microarchitecture
   pioneered in NexGen's Nx586 processor. The Nx686 processor extends
   this RISC86 microarchitecture by decoding multiple x86 instructions
   per clock cycle which are fed into seven execution units. These
   consist of two integer execution units, one floating point, one
   multimedia, one memory load, one memory store, and one branch
   execution unit. Advanced computer architecture techniques of
   speculative out-of-order execution and two-level branch prediction are
   used for increased performance.

   In order to feed the high speed execution units, the Nx686 processor
   incorporates the industry's most advanced cache. The on-chip L1 caches
   consist of a 16KB instruction cache and a 32KB data cache. Like the
   Nx586 processor, the Nx686 processor has an integrated L2 cache
   controller with a private bus to off-chip SRAMs, allowing the L2 cache
   memory to operate at the same speed as the Nx686 processor. The L2
   cache size can be as large as 2MB.

   TARGETED AT MAINSTREAM PC MARKET

   From the onset, the Nx686 processor is targeted to be used in high
   volume mainstream PCs in both commercial and home markets. The Nx686
   processor will incorporate a multimedia execution unit for
   acceleration of multimedia algorithms and low power system management
   features for portable PCs.

   The die size is projected to be smaller than Intel's announced die
   size for the Pentium Pro, offering the potential for significantly
   lower costs. In addition, the L2 cache is designed to be used with
   off-the-shelf synchronous pipelined burst SRAMs. Such SRAMs are
   commodity products, with wide availability, and thus have the
   potential to be lower in cost than Pentium Pro's announced internal,
   single-chip SRAM which has an expensive dual cavity package. The L2
   cache was designed to offer system designers programmable
   configurations which allow for a range of price/performance PCs.

   The Nx686 processor is supported by the same NxPCI/NxMC chipsets
   that are currently used in Nx586 based systems.

   NexGen, Inc. (Nasdaq: NXGN) develops and utilizes industry-leading
   processor technologies to deliver high performance x86 processors to
   mainstream PC users. The Milpitas, California-based company currently
   holds many patents for its leading-edge x86 processor technology and
   has several more patents in process. For product information, call
