If you wish to make a computer from scratch...

The Megaprocessor is a 16-bit computer made almost entirely from discrete electronic components (individual transistors, diodes, resistors, capacitors and LEDs). When finished it will measure 14m wide x 2m tall. [more inside]

Things CPU architects need to think about

Things CPU architects need to think about. Bob Colwell gave this lecture in 2004, for the Stanford University Computer Systems Colloquium (EE380). Colwell was the chief architect of the Pentium Pro, Pentium II, Pentium III, and Pentium 4 processors. [About 90 minutes, Windows Media format] [more inside]

...but can it run Crysis?

According to a customer report on the TribalWar forums, Newegg.com accidentally shipped bogus Intel i7 920 Retail CPUs. There are photos on Overclockers Forums and HardOCP. There's even a YouTube video of the fake CPU, fan and manual.

And I had hyperthreading, which was popular at the time...

Grandpa laces up his skates: How would a single core, 3.8 GHz Pentium 4 670 from 2005 compete against the latest offerings of AMD and Intel? How about a 2007 quad-core, the 2.4 GHz Core 2 Quad 6600? The Tech Report finds out in a Huge 14-way Roundout, including a price-performance evaluation (2nd perspective). For the release of AMD's new midrange DirectX 11 graphic card, the somewhat disappointing ATI Radeon HD 5830, they've done Something Similar, this time pitting older cards, including a Nvidia GeForce 7900 GTX from 2006, against the newcomer and today's top performers.

Homebrewed CPU

Intel’s fabrication plants can churn out hundreds of thousands of processor chips a day. But what does it take to handcraft a single 8-bit CPU and a computer? Give or take 18 months, about $1,000 and 1,253 pieces of wire.

RISCy business

Great Microprocessors of the Past and Present : This list is not intended to be an exhaustive compilation of microprocessors, but rather a description of designs that are either unique, or representative designs typical of the period, not necessarily the first of their kind, or the best. It includes material from text books, magazine articles and papers, authoritative descriptions and half remembered folklore from obscure sources, as such, it has no bibliography or list of references. via Linkfilter. It gets a little technical at times, but it's interesting reading if you're into the guts of these fun little toys!

What happens when you take the heatsink off a running CPU?

What happens when you take the heatsink off a running CPU? The people at tomshardware.com find out by trying to fry four different processors. They also produced this excellent little video of them pulling heatsinks off running computers. You don't have to be a geek to appreciate burning silicon. You'll need the divx codec to view the video

Athlon + DDR:

Athlon + DDR: Bert McComas is a very highly respected analyst of the CPU and memory industry, and I always read his articles with great interest.

Intel has announced that they don't expect the P4 to be a significant part of their business until late 2001. According to McComas, if they don't change that plan, AMD is going to eat them for lunch, because the P3 is no longer competitive. The performance/price ratio for the new AMD stuff has to be seen to be believed. I think Intel is in major trouble, because informal reports are that a 1.5GHz P4 is about the same power as a 900 MHz P3.[more>

A while ago I posted about some guys who built a computer case out of a refrigerator the better to overclock their CPU. Those guys were wusses. REAL men use liquid nitrogen.

I've been thinking of making my own digital delay for several years, but I've been waiting for CPU prices to drop. Damned if Cirrus logic went and solved that with one chip.
