Dual Processor Motherboard...CPU and a Graphics Chip?

ISA, PCI, AGP, and PCI Express all have one thing in common: they are bus interfaces that allow you to extend the capability of your motherboard through add-ons such as a graphics and sound system, network connectivity, etc. We've already seen built-in sound and network systems, and basic integrated graphics. However, the graphics system is second only to the CPU in terms of power and performance, and is very relavent to the speed of the computer. The system bus is constantly improving to accomodate for the bandwidth demand of the graphics card. So why isn't such an important component an actual part of the motherboard? Just like we can choose a CPU and replace it when an upgrade is due, why can't we just pop out a graphics chip and replace it with a newer one?

I will admit that many of the newer motherboards are crowded enough as it is, but integrating the graphics chip into the motherboard, along with its own set of memory, would eliminate the bottleneck of the PCI bus (assuming the graphics chip is connected through HyperTransport or a similar technology) and make the graphics system a more regular and cost-effecient upgrade. All that would have to be replaced is the graphics chip; no board or memory to increase the cost.

Although a nice solution, there are a few negative aspects to consider.

- First of all, if the graphics chip ever changed in size, the motherboard would have to be replaced. However, if this method was ever adopted, the lifespan of the graphics architecture would be about the same as the CPU, so an upgrade should entitle some sort of processor upgrade as well.
- This option would be a limiting factor for people with older systems. AGP has been around for at least 5 years, a lot longer than a typical upgrade.
- The graphics interconnect system would be limited to the technologies present on the motherboard. On current graphics cards, the speeds between the graphics chip and the memory are typically "the latest and greatest". I believe some graphics cards use DDR2 and have a 1 GHz bus, which may be about right for current PC's, but using a graphics chip on an older motherboard would limit the graphics system.

From a technology standpoint, having the graphics chip on-board would be a more efficient solution overall. However, the positive aspects have to outweigh any negative ones, and in this case, the race is close. I guess we'll see what happens in the future, especially when Intel comes up with a solution similar to HyperTransport.

Looks like the online music industry is moving in the right direction...Buy.com's music store now offers a choice in bitrate. When you purchase a song, you can choose whether you want to download a 256 kbps or 128 kbps version of the song. It's WMA so 256 is as high as you can before you hit lossless. The prices are also pretty reasonable; although most songs seem to be $.99 each, it was only $7.99 for the Skindred album. Unfortunately, not all of the songs are available at 256 kbps yet, so I'll have to hold off for now. Of course, the selection is limited to mostly popular artists, so it's hard to find some independent bands. With the number of available songs increasing and bitrate approaching lossless, soon we will be closer to a viable CD replacement. Next up: offering album inserts, CD art, and 5-channel audio.

Hello all! I'm just blogging from Illinois. I meant to see Strike Anywhere live, but traffic prevented us from doing so. Guess it's alright...having fun at my friend Keto's place drinking and stuff. Hopefully one day I'll be able to see Strike Anywhere live again...we'll see what happens. Gotta go...later.

Two Computers in One


At the Intel Developer Forum last week, Intel demonstrated dual-core chips incorporating the Itanium (Montecito) and the Pentium M (Napa) architecture. The Itanium system demonstrated contained 4 dual-core chips using HyperThreading, which appeared as 16 processors on the task manager in Itanium Windows (crazy, huh!). However, Itanium incorporates a new architecture that breaks away from x86, so don't expect to be using a desktop with an Itanium CPU for years to come.

I am particularly anticipating the arrival of the Pentium M dual-core chip, code-name Napa. The Pentium M architecture, designed by a team in Israel, is similar to the Athlon chips in that, instead of focusing on clock speeds, improvements to other parts of the chip are done to enhance performance. It is an excellent mobile chip that is very competitive with both Intel and AMD desktop offerings, and its lower power consumption makes it ideal in a dual-core setting.

I'm not writing this article to tout Intel's next generation of chips; AMD announced and demonstrated a dual-core chip of their own a couple of weeks ago. Since the Athlon64 architecture includes HyperTransport and the on-board memory controller, it has been designed from ground-up to support dual-core processors. I can't wait to read about all of these chips and the performance we will see out of them when they arrive sometime in 2005 (hopefully).

But there is one more remark I would like to make about Intel. Last fall, Intel announced a work-in-progress called Vanderpool. Vanderpool is a chip technology that will allow you to use one processor to run multiple operating system. With dual-core processors coming out next year, it would make sense to incorporate such a technology into these chips. Just imagine being able to run both FreeBSD and Linux (or Windows) on the same machine at the same time. With a multi-monitor and keyboard/mouse configuration, you could be playing a game on one core and watching a movie on the other without much impact on either tasks.

I can't wait for Vanderpool to be introduced into the PC market. With a technology like that, I think I might have to jump back to the Intel camp, or AMD will definately have to take advantage of their cross-license agreement, if possible. One other note I wanted to make about Vanderpool is how Intel could use it to gain market share with Itanium. Itanium has been slow to catch on due to high costs and limited software availability. Since Intel has already announced their plans for dual-core Itanium, it would be pretty cool to see a dual-core Itanium-Pentium chip. With Vanderpool, Intel will be able to vouch the ability to run native Itanium and native Pentium applications. Although both cores cannot be combined, it would be a good entry-level product to get people to start using Itanium. I guess we'll see what Intel decides to pull out of its sleeve in the coming years.

Reverse engineering software to create computer viruses has always been looked down upon by companies and users alike, but rarely do we take a moment and look at how amazing viruses are. A convention, originally held in Frankfort, Germany in 2002, is being held this year in the U.S. and Denmark. People will be able to infect disconnected computers to watch a virus propogate and play a game to see the large scale effects of them. If anyone wants to head over to Brown University this month, I'm down...the event started September 11 and will end October 4.
