Pentium 4 Architecture In Depth, Part 1
By Johan De Gelas on Monday, January 29, 2001 10:31 AM EST
Simply
assuming the Pentium 4 was designed for high clockrates, and that Intel has thrown
all other considerations overboard, however, is a bit too simplistic. No, there
must be more!...

Mustang VS Pentium 4: Design Decisions
By Johan De Gelas on Monday, October 23, 2000 9:00 AM EDT
Are double pumped, hyperpipelined, low latency designs the only future for x86? Will future designs from AMD and other competitors be similar to Intel's innovative seventh generation core?...

Ace's Guide to Memory Technology, Part 2
By Johan De Gelas on Thursday, August 3, 2000 9:15 AM EDT
The battle between Rambus vs (DDR) SDRAM is one of the hottest
discussion topics on the net today. Some people feel as if it has become an "Intel versus AMD" flamewar or a more typical...

Ace's Guide to Memory Technology
By Johan De Gelas on Thursday, July 13, 2000 1:33 AM EDT
We at Ace's Hardware decided to forget the rumbling in the courts
and focus on what is our duty: making sure that you are well informed. No better weapon than a comprehensive article to...

Binaries Vs Byte-Codes
By Chris Rijk on Friday, June 2, 2000 12:00 PM EDT
There are several reasons why Java could be thought to be inherently
slower than C for pure performance. For starters, Java is optimized at
run-time, instead of compile-time....

The Quest for Better Performance, Part 2
By Johan De Gelas on Sunday, April 23, 2000 3:39 PM EDT
In our previous article, we hunted for performance
bottlenecks and we have discovered quite
a few interesting bottlenecks. In this article we will try to
solve these bottlenecks....

The Quest for Better Performance
By Johan De Gelas on Friday, April 21, 2000 3:07 AM EDT
Performance is limited by certain bottlenecks, that is what this article
is all about. We will try to find out what exactly are the bottlenecks
in a top notch system of today....

Inside Tech: The UltraSPARC III
By Chris Rijk on Friday, February 25, 2000 12:01 AM EST
Increasing cache sizes is not as effective as it used to be, ILP is not as effective as it used to be, increasing clock frequency by lengthening the pipeline is not as effective as it used...
