Intel CPU for Desktop PC: Past, Present, Future
Cheng-Han Du
2
Moore’s Law Proposed by Intel co-founder Gordon Moore
The number of transistors that can be inexpensively placed on an integrated circuit is increasing exponentially, doubling approximately every two years. Similar phenomena can be observed in other computer-related technology.
3
Intel-Based CPU: The Past
80286 80386 80486 Pentium Pentium Pro, 2, III (Celeron) Pentium 4, Pentium D Pentium Dual-Core, Core 2
4
80286 Great performance improvement compared with its predecessor
16-bit architecture CPU clock: 6 ~ 25 MHz 1.5 micron process Milestone of personal computing
5
80386 32-bit architecture CPU clock: 16 ~ 40 MHz
1.5 ~ 1.0 micron process
6
80486 Pipelining Cache-in-chip CPU clock: 16 ~ 100 MHz
0.8 micron process
7
Pentium (P5) Superscalar – two pipes 64-bit data path
U – Handle any instructions V – Handle the simplest and most common instructions 64-bit data path Not 64-bit instruction set CPU clock: 60 ~ 300 MHz 0.8 ~ 0.25 micron process MMX (later models)
8
Pentium Pro, 2, III (P6) Focus on enhancement of multimedia and gaming performance. CPU clock: 150 ~ 1400 MHz 0.5 ~ 0.13 micron process Competitor: AMD K5, K6, K6-2
9
Pentium 4, Pentium D (NetBurst)
CPU clock: 1.3 ~ 3.8 GHz 0.18 ~ micron process Fierce competition against AMD’s Athlon Focus on high clock rate Pentium D Dual-core (2X1) CPU clock: 2.66 ~ 3.73 GHz 90 ~ 65 nm process Hyperthreading
10
Pentium Dual-Core, Core 2 (Core)
Dual-core or Quad-core CPU clock: 1.6 ~ 3.2 GHz 65 or 45 nm process Focus on performance per clock
11
Recent Problem on CPU Current leakage Heat and cooling
Power consumption Process size and physical limit
12
Future Development Near-term Long-term More cores parallelism
Smaller size Long-term Optical bus Optical processor Clockless CPU
13
Other Possible Way? Next time: video card
