- 2010-Apr-11: Intel has constructed a single chip with 48 processors on it, this is going to be made available to universities for research purposes. 
- 2010-Mar-09: Slashdot discusses the difficulty of selecting CPUs and GPUs due to the strange naming and numbering systems that are used these days. For comparison purposes the site: CPUBenchmark.net has a number of good performance charts that span a wide range of CPUs, as well the companion site VideoCardBenchmark.net compares GPUs. 
- 2010-Jan-16: A presentation from the JVM Languages Summit 2009 that talks about how modern CPUs function. 
- 2009-Sep-01: How many cores will our CPUs get in the future, and why don't we already have 1024 core based machines. This article blames the lack of applications that can use multiple cores. 
- 2009-May-08: Not all of Intel's modern CPUs have support for VT virtualization mode, though it appears that most of AMD's CPUs do. This could be of particular annoyance to users of Windows 7 that want to use the XP mode. Discussed here on Slashdot.  
- 2009-Mar-06: NVidia has built a set of single-chip computer system devices it calls the Tegra processors, these are based on an ARM processor core integrated with all necessary additional support circuits. One logical application of these would be to the netbook market allowing the production of lower cost, smaller and most significantly, low power consumption devices.  
- 2008-Dec-16: Slashdot discusses an ExtremeTech article which presents a performance study of Intel's current crop of quad processor CPUs (including the old Q6600 and the newest Core i7 chips). Looks like about 30% is the improvement you could get by spending 2 to 3 times as much as the $200 a Q6600 goes for. And if you are looking for faster video transcoding its probably still better to wait for a good GPU implementation to appear. 
- 2008-Aug-17: The AMD Athlon 64 2000+ appears to outperform the Intel Atom and consumes less power. This also has the advantage that it can be run on any AM2 or AM2+ socket motherboard. It also appears that the AMD solution may have a more efficient supporting chip set, giving it a significantly lower system power consumption (not to mention more features). The Celeron 220 is apparently about 29% faster than the Atom, which also makes it faster than the 2000+ chip - but it consumes more power. 
- 2008-Jul-20: Slashdot discusses liquid metal based CPU heat sinks which will probably be the next fad in CPU cooling. Perhaps these are using alloys based on gallium, some of which melt near room temperature. Bismuth and indium can also be used in these low melting point alloys. 
- 2008-May-21: Intel's Atom processor may not be offering a big performance boost to the low-power market. 
- 2008-May-01: The Tile64, a 64 processor CPU appeared in 2008, along with a PCIExpress development board and a Linux-based development kit. They claim one of these chips can outperform a dual-core Xeon by a factor of 10. Might be just the thing for some fast ray tracing. Though with the development cards hosting a pair of 10Gbit ethernet ports the initial applications are probably going to be in the internet packet sniffing and routing fields. 
- 2008-Feb-05: While not a CPU, the Curta was probably the first hand-held calculating devices capable of long multiplication. It was also a pretty neat device that had a wonderful feeling to it, rather like using a Nikon F1. 
- 2007-Dec-28: The AMD Phenom is supposed to be compatible with AM2 motherboards (perhaps after a BIOS upgrade) but Tom's Hardware tested 10 boards and found this to be true of only 2. 
- 2007-Oct-09: AMD has introduced some new 45-watt processors, which would be useful in lower power appliance (i.e. such as DVR) computers that don't need super-fast processors but do get a lot of run time. 
- In Sept'07 Toshiba
announced their SpurEngine video processing chip, this is based on
the Sony Cell processor technology used in the PS3, it looks like they
are going to integrate this into some of their future laptops to give
them a boost in the video editing (trans-coding) department. This could
be a significant advancement, I wonder if anyone is going to make a
PCI card to allow a video processing accelerator to be plugged into
existing systems. This could also help with power consumption, as its
possible that one of these chips could consume less energy that a
general purpose CPU to do the same overall task, which would be good
for laptops. LeadTek's HPVC1100 puts a SpursEngine in a small external enclosure for connection to a laptop (or perhaps some other computer).
In Aug'07 Tilera
announced their new 64 core processor the TILE64. While this is a
RISC chip (rather than an x86 processor) it may make its way to the
desktop by some Linux variant.
In Feb'07 AMD
showed their new Barcelona quad-core CPU, the unique thing about
this is that each core also has a vector math processor.
CPU from Intel will contain 4 cores on a single chip and ship in
Nov'06, this will run in existing 775 socket motherboards and looks
like it will bring quad-CPU functionality to the desktop. Here is a preview
of the performance that can be expected. The Core 2 Quad got launched
in early Jan'07.
has returned as some of the current (June'06) generation of CPUs
can be clocked at up to 4GHz
In Jun'06 Intel started showing their new Conroe CPU, this
looks like it could bring a 10-25% increase in performance
in Jun'06 AMD announced their 4x4 chips, which really will be dual
processor, dual core motherboards - so a 4 CPU "consumer"
workstation will soon be possible. These are being targeted at gamers
as they will support a pair of dual GPU graphics cards (for 4 times the
rendering power). I wonder what size of power supply you'll need to run
a high end system?
Intel's hyperthreading system may actually reduce

strong competitor to x86 chips some day.

In Oct'04 VIA announced plans to get into the 64bit
processor race. Plus their first dual processor
VIA chip motherboard.
And it looks (Sept'04) that the end
is in sight for the Itanium, maybe it'll die out before HP stops
making the Alpha chip, now that would be fitting.
of the road has been announced for the DEC Alpha processor
roadmaps (Aug 2004) for both Intel and AMD are discussed
AMD and Intel are both planning to introduce dual-CPU
on a chip processors in 2005. I love working on dual processor
boxes, so this should make quad processor boxes affordable...
a quiet gaming system, discussed
on Slashdot, this used an Antec Sonata II case and lined it with a
pre-cut acoustic foam solution from AcoustiPack.
AcoustiPack also makes quiet rack mount cases.

In case you are confused by Intel's
recent entry against AMD's 64 bit processor, it appears that Intel
has finally copied what AMD did, so the two processors will be able to
run the same software.

How does the VIA

Duron? Apparently not very well.
For comparing different computer architectures the SPECmark

between the Athlon and Athlon-MP chips?
now that the 2GHz Pentium 4 is out Intel seems to have regained
the lead over AMD, according to this article
at least. Where the Athlon 1.4GHz seems to be lagging the most is in
CODEC type applications, which this article talks about a lot.
Here is a 1U
