The Am386 CPU is a 100%-compatible clone of the Intel 80386 design released by AMD in March 1991. It sold millions of units, positioning AMD as a legitimate competitor to Intel , rather than being merely a second source for x86 CPUs (then termed 8086-family ).
In computer architecture, speedup is a number that measures the relative performance of two systems processing the same problem. More technically, it is the improvement in speed of execution of a task executed on two similar architectures with different resources.
Improving part A by a factor of 2 will increase overall program speed by a factor of 1.60, which makes it 37.5% faster than the original computation. However, improving part B by a factor of 5, which presumably requires more effort, will achieve an overall speedup factor of 1.25 only, which makes it 20% faster.
In Windows Vista and 7: "Minimum processor state" found in "Processor Power Management" of "Advanced Power Settings" should be lower than "100%". Also In Windows Vista and 7 the " Power Saver " power profile allows much lower power state (frequency and voltage) than in the " High Performance " power state.
The performance increase of the 80286 over the 8086 (or 8088) could be more than 100% per clock cycle in many programs (i.e., a doubled performance at the same clock speed). This was a large increase, fully comparable to the speed improvements seven years later when the i486 (1989) or the original Pentium (1993) were introduced.
As of 2010 the fastest PC processor reached 109 gigaFLOPS (Intel Core i7 980 XE) [51] in double precision calculations. GPUs are considerably more powerful. For example, Nvidia Tesla C2050 GPU computing processors perform around 515 gigaFLOPS [ 52 ] in double precision calculations, and the AMD FireStream 9270 peaks at 240 gigaFLOPS.
On April 14, 2003, Intel officially launched the new Pentium 4 HT processor. This processor used an 800 MT/s FSB (200 MHz physical clock), was clocked at 3 GHz, and had Hyper-Threading technology. [23] This was meant to help the Pentium 4 better compete with AMD's Opteron line of processors. Meanwhile, with the launch of the Athlon XP 3200+ in ...
The later "Dixon" mobile Pentium II would emulate this combination with 256 KB of full-speed cache. In Intel's "Family/Model/Stepping" scheme, the Pentium II OverDrive CPU identifies itself as family 6, model 3, though this is misleading, as it is not based on the family 6/model 3 Klamath core.
