AMD Announces 65-nm Chips, Touts Power Savings 234
Several readers wrote in about AMD's entry into the 65-nm manufacturing generation. The company introduced four chips to be manufactured with 65-nm process in the first quarter of 2007 to replace existing 90-nm chips in their lineup. AMD is playing up the power economy of its line, claiming that even its existing 90-nm parts consume less than 50% the power of Intel's Core 2 Duo, averaged over a typical day's usage, while the new 65-nm chips will be even stingier with power. Next stop, 45-nm. The article says that AMD has a goal of catching up within 18 months to Intel's lead on the way to 45-nm technology.

Of course, since Intel will also be moving forward over the next 18 months, they might end up still in the lead. Making a huge turnaround like they did (from Netburst to Core) in such a short time is remarkable. Creating an architecture and setting up the process and designing a generation of chips takes a looooong time. Kudos to Intel for that. Now the ball is in AMD's court, and they have to respond.
At the high end, of course, Intel rules. What about processors that normal people buy?
I was recently looking at a Core2Duo review, and noticed something interesting. At each brand's bottom end (E6300 vs. X2 3800), Intel outperformed AMD. The problem in my mind, however, is that Intel's bottom-end starts at a higher price point than AMD's. Very smart marketing move by Intel. However, If you match the processors price-to-price, the E6300 matches up against the X2 4200 (both currently around $180), and there is relatively little performance difference. In other words, the price/performance metric really isn't in anyone's favor.
Another smart (but a little slimy) marketing move Intel has made is in the power dissipation numbers. AMD quotes their CPU's maximum dissipation, and Intel quotes a power figure for some arbitrary (under 100%) CPU load. Intel looks good here....until you actually measure a system's power draw at the outlet, and find that again, there's not that much difference. This may (and probably will) drastically change as AMD's 65nm parts get out, but we'll have to wait and see.

However that's not what most of us want. I want a feature rich system, I want my computer to be everything, do everything. Well for that I need hardware, and I'm willing to pay for it.
It would be like trying to compare frame rates between Ultima 1 and ES4: Oblivion. When you get down to it, Ultima 1 probably has a frame rate as fast or faster than Oblivion. Ultima 1 wouldn't have any trouble running at 30fps or more, even on 286 hardware. Oblivion can run under 30fps, even on an 8800GTX. However you are dealing with a totally different level of graphics. Ultima 1 was made to run in CGA which is 2D, 2-bit (4 colour), 320x200. Oblivion is full 3D with amazingly high geometry, 128-bit FP colour, 2560x1600 with anti-aliasing. Despite the speed being around the same, there is a difference.
While games are teh most pronounced difference, it's still there with other apps. Comparing Office to an old text mode Wordperfect app is meaningless. Ok, maybe for what you do you don't notice any difference, but many of us do. As a simple example, take a highly accurate, learning, in-line spell checker. I love that feature. Well, guess what? That takes resources. You couldn't do that on a really old computer, it just lacks the resources.
So if you are happy with what you have now, great, stick with it, but don't get mad that people want to find ways to use the new power. I do not buy a new graphics card to get higher and higher frame rates, 60fps is enough thanks that's all my screen does. I buy it for more an more features, at the same framerate. Likewise with processing in my computer. Everything is plenty fast now, my computer responds near instantaneously for normal tasks. So what I want is for my computer to do more. I want it capable of doing more complex things. In 1996 my computer played little postage-stamp sized videos, and used nearly 100% CPU to do it. Now it plays fullscreen HD videos and uses nearly 100% CPU (well ok, of one of the cores) to do it. I'm not pissed that it hasn't changed, I'm pleased with the increase in quality, the increase in features.

I would rather have a motherboard with a CPU design distributed, where the surface area is spread out in such a way, that is completely solid state without any moving parts to fail, namely, a CPU does no require active cooling.
The future lies in completly 100% solid state devices. What does this philosophy mean?
No CPU fans, no power supply fans, no harddrives (flash memory instead), no noise, no moving parts whatsoever. Distributed or minimized waste heat.
Reliability and shock resistance skyrocket. You can seal them inside waterproof and dust proof and fire proof boxes.
I've implemented these kind of computers, at critical network points, and literally you can plug them in FOR YEARS and forget about them.
They are absolutely silent. And absolutely low powered. And totally reliable. All of which, is a very beautiful thing from an engineering standpoint.
These guys need to hire me on their team, because the definition of what is going to be expected in computers is going to radically change in the near future. Computers are going to go under, they are going to become *embedded* in everything with no expectaions of mainenance to them at all and installed in harsh environments. They either work or they fail after decades of use (or preferably, never), and then you replace them.
Reliability is CORE, and to achieve it, computers are going to have to abandon all cruches and become purely solid state devices entombed in indestructible plastic modules.
How often have you ever reformated the drive on your wrist watch? Had to reinstall an OS on your cellphone? Had to replace the CPU fan on your calculator?
I often wondered, why in heck weren't motherboards encased in protective plastic casing, and the same for ISA / PCI / AGP / PCI-x cards.
