Fastest processor: Pentium III 700 MHz Also producing: PII, Celeron 266-666 MHz New productions: Pentium III PPGA 256Kb on-die cache and FBS 133 MHz Other products: Motherboards chipsets, AGP, graphical processors Current slots: Slot 1 & PPGA 370 Homepage: www.intel.com Intel introduced the x86 back in the early ' 80s. It was many years later that competitors arrived, like AMD & Cyrix. Intel always had the reputation of producing the fastest, most powerful and most reliable microprocessors. These days Intel is in a nastly situation... More competitors have arrived (WinChip & Rise) and AMD's marketshare is increasing. The Pentium III design is, untill now, not very different from the Pentium II. And negative publicity about an electronic serialnumber inside the Pentium III has not done much good. The fastest pentium III processor features 550Mhz. Intel has stopped production of Pentium II processors (excluding Celeron systems). The 'slot 1' (=the place where a processor connects to a motherboard) technology is used for Pentium II/III systems, which eliminates the bottleneck with the socket. Intel processor are best known for their superior quality and powerfull FPU (=mathetical) performance (great for gaming). There is a price tag on that, however. Intel will release a PPGA version of the Pentium III later this year. PPGA is a socket format that is also used for Celeron systems. Later this year, the JX chipset will be presented that will have a 133MHz bus and 4x AGP support. A processor codenamed 'Williamette' might be released early 2000. Its speed will be 800-1200Mhz! Intel has also designed a new processor architecture that intends to replace the popular x86. This is called IA-64 (codenamed 'Merced'). This CPU will probably be compatible with x86 instructions, but not for long.
Fastest processor: K7 Athlon 650 MHz Also producing: K6-2 and K6-III 266-550 MHz New productions: K6-3, K7 Other products: Telecommunications Current slots: socket 7/super 7 [future=slot_A] Homepage: www.amd.com AMD stopped production ofr the K6, which is replaced with the k6-2 processor (266-400MHz) including 3DNow instructions. The original design of the K6 was supplied with 24 new instructions (just like Intel did with MMX). These instructions will benefit 3D games that use DirectX6. To other games it will show little improvements. When game-developpers will support 3DNow in future games, 3DNow will be a serious threat to Intels Pentium II, although the business performance is almost equal. If not, the only advantage is the lower price of the K6-2. Cyrix and WinChip will also support 3DNow. Intel will release similar instructions, called MMX2 in the first quarter of next year. Soon, AMD will release the third-K6, codenamed 'Sharptooth'. This CPU has 256Kb on-die cache, similar to the Celeron Mendocino core. The K6-3 probably will beat the Pentium II at the same frequency. The K6-3 will be socket 7/super 7 compatible. The AMD K7 chip will run at 600+ Mhz, but will not be out until 1999. This slot will support slot A (which is similar to slot 1, only cheaper) and will also support 3DNow. The K7 will be based on Alpha's EV-6 protocols.

Fastest processor: MII 400 MHz Also producing: MX200, MX233, MX266, MII-300 New productions: MII 350, MXi Cayenne Other products: MediaGX processor Current slots: socket 7 Homepage: www.cyrix.com www.national.com Cyrix and IBM used to work together on their microprocessors. Cyrix mades the design and IBM produced. National Semiconductor, of which Cyrix is a wholly owned subsidairy, terminated this foundry agreement recently and it mass producing Cyrix itself now. Cyrix processors run at a different megahertz than Intel. Cyrix has developed a faster core. For instance: The 6x86-PR200 is really a 150Mhz processor (75Mhz busx2), but scores even higher than the Intel 200Mhz version. Therefore Cyrix gave their chips the PR-rating. Their latest processors are quite fast, close to the pentium II. Some tests say the new M II 300 processor sometimes even exceeds the pentium II 300Mhz! Cyrix CPUs score higher on business applications. Games, especially 3D, score much lower, because of a weak FPU (=the mathematical part of a processor) Cyrix/IBM is working on a new cpu core, nicknamed 'MXi', based on the Cayenne core. This will run at aprox. 350-450Mhz. "Cayenne will future a fully pipelined, dual-issue floating point unit and 15 new multimedia instructions to enable the highest-performance 3D graphics, DVD and 3D audio." The MXi will have improved FPU performance, an on-chip 3D accelerator and 3DNow support. It would be released in the second half of 1998, but its debut is delayed till early 1999. Cyrix has also discussed plans for the next generation processor core, nicknamed Jalapeno (M III). National Semiconductor has a broad cross-license agreement with Intel that gives Cyrix the right to do Slot 1. But officially, no decision has been made on Slot 1. Cyrix is awaiting the right opportunity, maybe when a partner comes along.
Cyrix has announced new M II 300/333/350 & 400Mhz, see NEWS

Other x86 CPUs:
WINCHIP C6 | ||
IDT www.winchip.com Socket 7 180-240MHz |
This company, launched in 1995, only recently took part in the CPU branche (1st half 1997) but is considered too be a good alternative. Their chip is much smaller (and therefore consumes less power) which makes it pretty cheap. The name "WinChip" comes from "Windows", as it is designed for MS Windows. A WinChip with 3DNow support, the Winchip2, will be released soon. | |
RISE MP6 | ||
RISE Tech www.rise.com Socket 7 166-266MHz |
The MP6 is a newcomer and only just released. Rise is focusing at the laptop market, but their chip will be available to the regular market also. There is not much information about its performance. IBM will produce a part of the Rise mP6 | |
x86 | ||
IBM www.ibm.com Socket ? ?? MHz |
Since the break-up with Cyrix, it is rumoured that IBM will start its own x86 line. IBM does now have an agreement with Rise, for whoom they'll produce processors for. | |
x86 | ||
Transmeta www.transmeta.com Socket ? ?? MHz |
Transmeta also plans to step into the x86 world. The most interesting thing about transmeta is that they want to transform x86 instructions into VLIW (Very Long Instruction Word) instructions. | |
G3 | ||
Apple www.apple.com www.motorola.com ZIF socket 233-400 MHz |
Since the G3, Apple machines are again very popular. And with right! The G3 is a very powerful processor, reasonably faster than a Pentium II/III at the same MHz speed. The fourth generation (G4) is coming very soon. The chips are being manufactored by Motorola and IBM. | |
21x64 | ||
Digital Alpha www.alpha.com Socket ? 525-667 MHz |
The Alpha processors are very powerful. They are used in high end facilities, such a servers. Unix systems (often used as internet servers) are based on Alpha processors. Altavista (an initiative from DEC, the producer of Alpha) is also use these chips. An Alpha server is very expensive though. | |
ULTRASPARC | ||
SUN www.sun.com Socket ? 250-400 MHz |
The 64-bit Ultrasparc II is manufactured by TI for Sun. Sun processors are also used in high end serversystems. The 400Mhz has 4Mb level 2 cache and costs over 4000 dollars. |
