The 8. 04. 86 was introduced in 1. It represents a fourth generation of binary compatible CPUs since the original 8. A 5. 0 MHz 8. 04. MIPS peak performance. The i. 48. 6 does not have the usual 8. Later, with the introduction of the Pentium brand, Intel began branding its chips with words rather than numbers. BackgroundeditThe 8. Spring Comdex in April 1.

Intel 8. 03. 86, with the addition of only a few extra instructions, such as CMPXCHG which implements a compare and swapatomic operation and XADD, a fetch and add atomic operation returning the original value unlike a standard ADD which returns flags only. From a performance point of view, the architecture of the i. It has an on chip unified instruction and data cache, an on chip floating point unit FPU and an enhanced bus interface unit. Due to the tight pipelining, sequences of simple instructions such as ALU reg,reg and ALU reg,im could sustain a single clock cycle throughput one instruction completed every clock. These improvements yielded a rough doubling in integer ALU performance over the 3. A 1. 6 MHz 8. 04. MHz 3. 86, and the older design had to reach 5. MHz to be comparable with a 2. MHz 8. 04. 86 part. Differences between i. An 8 k. B on chip level 1 SRAMcache stores the most recently used instructions and data 1. B andor write back on some later models. The 3. 86 had no such internal cache but supported a slower off chip cache which was not a level 2 cache because there was no internal level 1 cache on the 8. Tightly coupled pipelining completes a simple instruction like ALU reg,reg or ALU reg,im every clock cycle after a latency of several cycles. The 3. 86 needed two clock cycles to do this. Integrated FPU disabled or absent in SX models with a dedicated local bus together with faster algorithms on more extensive hardware than in the i. Improved MMU performance. New instructions XADD, BSWAP, CMPXCHG, INVD, WBINVD, INVLPG. Just as in the 8. GB memory model could be implemented by setting all segment selector registers to a neutral value in protected mode, or setting the same segment registers to zero in real mode, and using only the 3. CPU registers used as address registers as a linear 3. Virtual addresses were then normally mapped onto physical addresses by the paging system except when it was disabled. Real mode had no virtual addresses. Just as with the 8. On a typical PC motherboard, either four matched 3. SIMMs or one 7. 2 pin 3. SIMM per bank were required to fit the 8. The address bus used 3. A3. 1. A2 complemented by four byte select pins instead of A0,A1 to allow for any 81. This meant that the limit of directly addressable physical memory was 4 gigabytes as well 2.
