A SEMINAR ON 64 BIT COMPUTING

64 -bit Computing l l l The best and simple definition is enhancing the processing word in the architecture to 64 bits. Data processing speed does not change yet the data processed in a clock cycle increases two times. The addressable memory increases from 4 GB to 264 = 18 billion GB

64 -bit Computing

Is 64 -bit Computing necessary?

Benefits of 64 -bit Computing l l l Allowing applications to store vast amount of data in main memory Manipulating data and executing instructions in chunks that are twice as large as in 32 -bit computing. Allowing complex calculations with a highlevel precision.

32 -bit Computing l In a 32 -bit microprocessor; There are 32 -bit general purpose registers in the processor. There are 232 = 4 GB memory to be addressed.

32 -bit vs. 64 -bit Processors

64 -bit Registers

AMD Athlon 64 FX Processors l The AMD Athlon™ 64 FX processor is the world’s best PC processor. ” -- AMD Inc.

AMD Athlon 64 FX Processor Key features: l l l AMD 64 Technology Hypertransport Technology DDR Memory Controller On-Die Cache 3 DNow!Technology

Performance Tests The performance of the processor is tested in three different computation areas. l l l Computer Gaming Digital Media Office Productivity

Conclusion l 64 -bit computing is a necessary technology in the computer science areas which require larger memory and increased performance such as scientific computing, CAD/CAM, ERP/CRM solutions etc. . . l With new technologies improved, today AMD Athlon 64 FX – 55 processors have the best potential to fulfill 64 -bit desktop computing needs.
