The original Klamath Pentium IIs ran at 233 and 266 MHz, were produced in a 0.35 µm fabrication process and produced (for that time) an incredible amount of heat. They also worked with a 66 MHz front side bus, which was a speed that was inadequate for the CPU's design to show its full potential. A 300 MHz version was released later in 1997.
The Deschutes core Pentium IIs which debuted at 333 MHz in January 1998 were produced in a more suitable 0.25 µm fabrication process and ran significantly cooler. Support for 100 MHz front side bus speeds heralded decent performance improvements. During 1998, Pentium IIs running at 350, 400, and 450 MHz were also released. Pentium II-based systems also oversaw the introduction of the new generation RAM-standard, SDRAM (which replaced EDO RAM), and the AGP graphics bus.
Unlike previous Intel processors such as the Pentium and Pentium Pro, the Pentium II was packaged in a slotSlot 1 refers to the physical and electrical specification for the connector used by some of Intel's microprocessors, including the Celeron and the Pentium II. Slot 1 was a departure from the square ZIF PGA/SPGA sockets used for the Pentium and earlier pr-based form-factor rather than a socketA socket generally designates a cavity or region used for fitting and connecting some specific device. Physical sockets Electrical sockets A CPU socket is a physical and electrical specification of how to connect a CPU to a motherboard. In electronics, a one. This larger package was a compromise allowing Intel to separate the secondary cacheThis article is about the computer term. For towns with this name, see Cache, Utah or Cache, Oklahoma and for general sense Cache in general. In computer science, a cache is a collection of duplicate data, where the original data is expensive to fetch or from the processor while still keeping it on a closely coupled busThis article is about the form of transport. See computer bus or electrical bus for the use of the term in computing and electronics respectively, or places like Bus, Pas-de-Calais and Bus-Saint-Remy. The Bus, established by Mayor Frank Fasi, is Honolulu'. This separate cache was slower (running at half the processor speed) than that in the Pentium Pro, but solved the Pentium Pro's low yields allowing Intel to introduce the Pentium II at a mainstream price level.
A low-end version of the Pentium II - essentially a Pentium II with less (or sans) level 2 cache - was marketed under the name " CeleronA Celeron is any of a large number of different budget x86 microprocessors produced by Intel and marketed as a second line to complement their more expensive but higher-performance Pentium CPUs. The first Celeron was introduced in August 1998 and based on". The Pentium II XeonThe Xeon is Intel's current generation of server-class microprocessors for PCs. The first Xeon processor was released in 1998 as the Pentium II Xeon. The Pentium II Xeon uses either a 440GX or 450NX chipset. In 2000, the Pentium II Xeon was replaced by th was a high-end version intended for use on servers.
By early 1999, the Pentium III superceded the Pentium II.
