	Cyrix 6x86 - The Processor Emporium (UK)
		The Cyrix 6x86 range was introduced in 1995 as a rival to the Intel Pentium.
		The Cyrix 6x86 range possessed the most powerful processor core of any "x86" processor of its generation, leading to Cyrix using the same controversial P Rating system as the AMD K5.
		The Cyrix 6x86 processor suffered severe heat dissipation problems in early models, and some were destroyed by overheating whilst running.

	Cyrix - Wikipedia, the free encyclopedia
		Later in 1995 Cyrix released its best-known chip, the 6x86, which was the first Cyrix CPU to exceed the performance of the Intel chip it was intended to compete against.
		Cyrix had always been a fabless company: Cyrix designed and sold their own chips, but contracted the actual semiconductor-manufacturing to an outside foundry.
		Cyrix, whose product had been considered a performance product in 1996, had fallen to the mid-range, then the entry level, and to the fringe of the entry level and was in danger of completely losing its market.

		Like the original 6x86, it has an excellent integer performance that outperforms all other 6th Generation processors (including the Pentium 2) when compared at the same clock speed.
		The similarity to the 6x86 does not end here, and it thus also uses a PR rating system (albeit a more complicated one called the PR2).
		Continuing the tradition set by the 6x86 processor, the 6x86MX has the best price-performance ratio of the 6th generation processors.

	Cyrix Cx5x86 - Wikipedia, the free encyclopedia
		The processor was based on a scaled-down version of the "M1" core used in the Cyrix 6x86, which provided 80% of the performance for a 50% decrease in transistors over the 6x86 design.
		The similarly-named SGS-Thomson ST5x86 and IBM IBM5x86C were licensed rebrandings of the Cyrix design (IBM and ST physically produced Cyrix's CPUs for them), marketed separately but identical for practical purposes, apart from the availability of a 75 MHz edition which Cyrix did not bring to market, and slight differences in voltage requirements.
		The Cyrix 5x86 design, however, should not be confused with the similarly-named AMD Am5x86 which was essentially a fast 486 (not an all-new design like the Cyrix part) but which had broadly similar performance, used the same Socket 3, and was introduced at the end of the same year.

		The 6x86L was later released by Cyrix to address heat issues; the L standing for low-power.
		Note that the 6x86 and 6x86L weren't completely compatible with the Intel Pentium instruction set.
		It is for this reason that by default the chip identified itself as a 486 and disabled the CPUID instruction.

	The Cyrix 6x86 FAQ - Processor Identification and Replacement
		As I understand it, these chips, and their Cyrix equivalents have a "bug" which Microsoft has gotten around by disabling the cache when the chip is used with the NT4.0 operating system thus decreasing performance by 30% and effectively making the chip useless under the NT4.0 operating system.
		Cyrix has agreed to exchanged chips sold under their name so I would assume IBM (since it is the same chip, with the same bug) is doing the same.
		Cyrix needs only to see the receipt of sale for the chip and a receipt for windows NT4.0 and a creditcard number to which the new chip can be charged IF the defective chip is not returned.

		There's no doubt that the Cyrix 6x86 processor still has considerable difficulties in a lot of board designs.

	Cyrix 6x86 Processor Floating Point Performance Summary
		As a result, Cyrix chose to emphasize "parallelism" in the design of the 6x86™ processor to speed up software that intermixes these two instruction types.
		If one of the FLTs faults (the atypical case), the speculative execution capability of the 6x86 allows the processor state to be restored in such a way that it is compatible with the x86 floating point exception model.
		Cyrix believes that non-synthetic benchmarks based on real-world applications better reflect the actual performance users will achieve.

	Olympus MIC-D: Integrated Circuit Gallery - Cyrix 6x86 Microprocessor
		Although Intel never produced chips termed 586s or 686s, the Cyrix 6x86 microprocessors were designed to compete with the Pentium 166 and the Advanced Micro Devices (AMD) K5 PR166, the so-called "Pentium killer".
		Cyrix, a California Silicon Valley upstart, along with fellow clone masters Advanced Micro Devices, employed the reverse engineering concepts pioneered by the Japanese semiconductor industry to match and then leapfrog rival Intel's microprocessor innovations.
		Cyrix, with its partner IBM, continued the line with the 6x86L and 6x86MX processors with power ratings up to 233 MHz clock speeds, more refined fabrication techniques (from 0.65 down to 0.35 micron technology), and lower power dissipations.

		Cyrix maintains an approved motherboard list to help 6x86 buyers choose boards that are compatible with the chip.
		Cyrix intentionally decided not to spend time optimizing the FPU due to its lack of importance for most applications (which is true).

		6x86 also does checking to ensure that an instruction that writes to data already within the pipeline flush the pipeline and update the modified instructions properly.
		If the 6x86 speculation level was last incremented by a conditional jump, then the 6x86 doesn't allow any instructions to change the speculation level until the conditional jump has been properly resolved.

	Talk:Cyrix 6x86 - Wikipedia, the free encyclopedia
		I'm not doubting that there was one, but my feeling is that it is better to ignore parts that were not marketed in more than tiny test quantities.
		The PR-90 certainly didn't figure in Cyrix's original public release plans, nor have I ever heard of one in the flesh.
		The Cyrix 6x86MX should be mentioned too, it went up to PR350.

	Cyrix 6x86MX ("M2")
		The successor to the 6x86 and 6x86L is the 6x86MX, introduced in June 1997 and intended to compete with AMD's K6 and Intel's Pentium with MMX and Pentium II processors.
		Cyrix fans are fond of pointing out that the Cyrix chips get more performance per unit of clock speed, but of course, the internal design and maximum clock speed are dependent.
		Cyrix has this time made things even more confusing, if that's possible, because their PR166 and PR200 chips are compared to Intel's Pentium with MMX 166 and 200, but the 6x86MX-PR233 is compared to the Pentium II 233.

		The bus interface unit is responsible for the communication between the motherboard (hence any component on the motherboard) and the processor's internal execution units.
		Not much to say here, so I took this from the Cyrix website: The memory management unit translates the linear address supplied by the instruction unit into a physical address to be used by the unified cache and the bus interface.
		This is the same floating point unit used in the original 6x86 processor.

	The PC Technology Guide
		Unveiled in October 1995, the 6x86 was the first Pentium-compatible processor to reach the market and the result of a collaboration with IBM's Microelectronics Division.
		Once Cyrix readjusted its sights and accepted its position as a low-cost, high-performance alternative to the Intel Pentium series, the chip made a significant impact in the budget sector of the market.
		Since a 6x86 processor was capable of an equivalent level of performance to a Pentium chip at a lower clock speed, Cyrix collaborated with a number of other companies to develop an alternative to the traditional clock speed-based rating system.
