CYRIX ANNOUNCES 6x86TM PROCESSOR FOR
HIGH-PERFORMANCE DESKTOP MARKET
Delivers Industry-Leading Performance
for Windowsr and Windows Applications
Richardson, Texas  October 6, 1995  Cyrix Corporation (NASDAQ: CYRX) today
formally unveiled its 6x86 processor family, previously known as the M1. The
6x86 processor represents an unprecedented performance advancement in the
evolution of the x86 architecture found at the heart of all IBM-compatible PCs
today. Its architecture enables industry-leading performance running Windows and
PC applications. The 6x86 processor family represents the first real challenge
to Intel's performance leadership.
"The 6x86 processor was designed for compatibility and optimum performance
running all PC software," said Jerry Rogers, president and CEO of Cyrix.  "By
anticipating the needs of today's as well as tomorrow's PC users, we expect the
6x86 product line to remain competitive through the 90s."

Desktop Performance Leadership
Cyrix revealed a Winstoner 95 performance rating of 217, which rivals published
test results from the fastest Pentiumr-133 systems. Industry reports show the
150 MHz Pentium Pro processor, formerly known as the P6, runs up to 20 percent
slower than the Pentium 133 running Windows desktop software.
At the initial clock speed of 100 MHz, the 6x86 processor gives PC manufacturers
the ability to build systems that compete with Pentium-133 and Pentium Pro-150
systems on Windows software.
"As the benchmarks indicate, raw clock speed of a processor is no longer an
absolute measure of its performance," said Steve Tobak, vice president of
corporate marketing at Cyrix. "The 6x86 processor's architectural superiority is
a critical factor in its performance advantage.
 "The bottom line is that no processor today runs Windows software faster than
the 6x86," stated Tobak.
Sixth-Generation Architecture for Today's Designs
The Cyrix 6x86 is a sixth-generation superscalar, superpipelined processor. The
chip features register renaming, data dependency removal, multi-branch
prediction, speculative execution and out-of-order completion capabilities. It
has an 80-bit floating point unit and a 16K primary cache.
The Cyrix 6x86 processor is easy to implement in today's desktop designs.  Its
296-pin grid array (PGA) package is compatible with the robust P54C socket that
is widely used in today's 64-bit platforms, with minor modifications.
The 6x86 processor requires a single 3.3-volt supply and includes 5-volt
tolerant I/O buffers. Extensive on-chip power management features enable "green
PC" implementation.
Price and Availability
The 100 MHz Cyrix 6x86 processor is available now, priced at $450 each in
quantities of 1,000.

Las Vegas, Nevada -- November 13, 1995 -- At the COMDEX trade show heretoday,
Cyrix Corporation (NASDAQ: CYRX) demonstrated the industry's fastestWindowsr
95 processor, a new 120 MHz version of its flagship 6x86oprocessor family.
According to industry-standard benchmarks, the 120 MHz6x86 processor runs
32-bit applications under Windows 95 faster than anyexisting desktop PC
processor. Its performance is also expected to rivalthat of the 166 MHz
Pentiumr processor, as yet unreleased. A 120 MHz 6x86processor-based
reference system achieved a score of 349 on CPUMark32, abenchmark
specifically developed to gauge the performance of a processorsubsystem
running 32-bit applications under Windows 95."The fastest processor for
running Windows 95 just got faster," said SteveTobak, vice president of
corporate marketing at Cyrix. "Cyrix continues tooffer power users a higher
performance alternative that takes advantage ofWindows 95's advanced
capabilities."A demonstration of the 120 MHz 6x86 processor is being featured
in theCyrix booth (L4202, North Hall, Las Vegas Convention Center) at the
COMDEXtrade show. The 120 MHz chip is expected to ship in sample quantities
tocustomers in December, with production quantities planned for the
firstquarter of 1996. Systems based on the 120 MHz 6x86 processor are
alsoexpected to appear in the first quarter.Acer, Apple, AST Computer, Canon,
EPSON and Sharp are among the PCmanufacturers demonstrating 6x86 or 5x86o
processor-based products at theCyrix COMDEX booth.50 Percent Die Shrink
Increases Production, Clock SpeedsA re-layout of the original 6x86 processor
has resulted in a 50% die shrinkby using all five metal layers of the IBM
manufacturing process. Theoriginal die used only three. Due to the solid
performance andcompatibility demonstrated by this re-layout of the 6x86 die,
Cyrix hasconverted all IBM production to the smaller, five-layer-metal die.
The 50%die shrink enables increased production capacity, lower costs and
higherclock speeds, as demonstrated by the 120 MHz part. The smaller die
isexpected to yield both 100 MHz and 120 MHz versions.The Cyrix 6x86
