It was manufactured using a 0.25 micrometre process, ran at 2.2 volts, and had 9.3 million transistors. Khanna, R. et al. It was also made pin-compatible with Intel's Pentium, enabling it to be used in the widely available "Socket 7"-based motherboards. An enhancement of the original K6, the K6-2 introduced AMD's 3DNow! RISC86 core. The release of the 266 MHz version of this chip was not until the second quarter of 1998, when AMD was able to move to the 0.25-micrometre manufacturing process. The processor included support for MMX instruction set. predecessor, an. As the market moved on, AMD released a long series of faster K6-2 parts, the best-selling ones being the 350, 400, 450, and 500. Picture of: AMD K6 166 - AMD-K6/PR2-166ALR, Picture of: AMD Mobile K6 266 MHz - AMD-K6/266ACZ. The successor to the K6 is the Athlon . Another advantage of RISC core is the ability to run at frequencies (1998). The K6 microprocessor was launched by AMD in 1997. Despite the name, the little-known K6-2+ was based on the AMD K6-III+ design (model 13) with 128 KiB of integrated L2 cache and built on a 0.18 micrometre process (essentially a K6-III+ with half the L2 cache). "A 0.25µm x86 microprocessor with a 100MHz Socket 7 interface". AMD K6 family is the second generation of x86-compatible 32-bit processors designed by AMD. This allowed many users to run their K6-2+ 550 MHz and often even a K6-2+ 500 MHz at a speed of 600 MHz simply by setting the motherboard clock multiplier to 2. The K6 had a considerable impact on the PC market and presented Intel with serious competition. desktop K6 microprocessors. This page was last edited on 2 October 2020, at 19:03. Initially, the AMD K6 processors used a Pentium II-based performance rating (PR2) to designate their speed. K6-2 microprocessors utilize L2 cache located on a motherboard - this cache runs at bus frequency, i.e. at 100 MHz at most. The K6-2 is an x86 microprocessor introduced by AMD on May 28, 1998,[2] and available in speeds ranging from 266 to 550 MHz. However programs needed to be specifically tailored for the new instructions and despite beating Intel's SSE instruction set to market, 3DNow achieved only limited popularity. Performance of the two chips was similar: the previous K6 tended to be faster for general-purpose computing, while the Intel part was faster in x87 floating-point applications. It was manufactured using a 0.25 micrometre process, ran at 2.2 volts, and had 9.3 million transistors. the RISC86 core to execute up to 4 RISC-like instructions per cycle. *Testing by AMD performance labs on 10/07/2019 comparing an AMD Ryzen™ Threadripper™ 3970X and AMD Ryzen™ Threadripper™ 3960X vs. Intel© Core™ i9-9980XE in the Cinebench R20 nT benchmark test. frequency of the processor was the same as the real frequency. It rapidly established an excellent reputation in the marketplace and offered a favorable price/performance ratio versus Intel's Celeron 300A. The K6-2 is an x86 microprocessor introduced by AMD on May 28, 1998, and available in speeds ranging from 266 to 550 MHz. The introductory K6-2 300 was by far the best-selling variant. † The AMD Fan Store is available in the US and Canada only. Initially, the K6 processors used Pentium II Rating (PR2) to The PR2 rating was dropped because the rated AMD produced both desktop and mobile K6 processors. The AMD K6 is based on the Nx686 microprocessor that NexGen was designing when it was acquired by AMD. higher then processors with CISC-based cores. To battle the Pentium 2's dominance on floating point calculations the K6-2 was the first CPU to introduce a floating point SIMD instruction set (dubbed 3DNow! [3][4], Most K6-2+ motherboards did not support a clock multiplier setting greater than 5.5 since 550 MHz was the highest official speed of the K6-2+ (100*5.5 = 550) but a little known feature of the both the K6-2 and K6-2+ was that it interpreted the motherboard clock multiplier setting 2 as 6. The AMD K6 is a superscalar P5 Pentium-class microprocessor, manufactured by AMD, which superseded the K5. The K6 was originally launched in April 1997, running at speeds of 166 and 200 MHz. The K6-2+ was specifically designed as a low-power mobile CPU. A later variation of the K6 CPU, K6-2, added floating-point-based SIMD instructions, called 3DNow!.
