1 The Athlons x86 Architecture
First AMD to have x*6 instruction set Its 2048-entry branch prediction table is 4 times the size of Pentium III FPU problem 3D now technology

2 The New Slot Design First AMD to have a new slot design
Slot-A is similar to Slot-1 Easier for motherboard manufacturers Easier for asssemlers

3 The .25 micron transistor and the switch to .18 copper.
Current .25 micron Made switch to .18 copper before Intel

4 128KB of L1 Cache When introduced twice as much as competitors.
Programmable backside L2 cache can run at any ratio.

5 The Athlon's Busses AMD Intel
GTL + option vs. Digital's EV6 bus protocol 1.6Gb/s of bandwidth vs. Intel 800mb/s Multi processor adveantage AMD Intel

6 Negative Aspects of AMD Athlons
Marketing Heat Cache Storage

7 Marketing and Heat Lack of Promotion Heat slowly degrades performance
BIOSTAR, FIC, AMD Heat slowly degrades performance cooling fans and heat sink

8 Cache Storage Cache Speed: Latency Bandwidth Clockspeed

9 On-Die Easier to make L2 faster Closer Connections Cheaper

10 AMD has a brighter Future
Better performance than Pentium IV Cheaper than Pentium IV Will have more memory bandwidth than Pentium IV. It uses the most popular system configuration among hardware enthusiasts.
