AMD - Piledriver chitchat

CAC reduction

That's a good sign

It seems the Trinity thin and light laptop,looks like it is a Samsung Series 5,if you look at the shape:

More Trinity ramblings from good old Charlie, with a promise of further ramblings to come.

Wait, Trinity laptops aren't actually available yet?

They seem to be some parts of the world.

I'm personally saving money to buy an AMD ultrabook for hopefully under £700, as long as the battery lasts more than 5 hours so I can use it for university and it will play diablo 3. Hopefully they will also produce a higher res screen one, after my pc monitor and having documents side by side my old lappy seems so useless

Took months after release for me to find an E-350 netbook despite AMD saying they sold millions of CPUs. Perhaps the same is happening again.

Seems to have the best integrated graphics for Diablo, but a cheap laptop and also a desktop might give better results for that sort of money.

More transistor count shenanigans.

Sounds meaningless to me. Do you think they meant "De-coupling cells"??

That's what i was getting at. That Aussie chap who leaked the benchmarks had one weeks ago now. Launch/reveal has been and gone and i still haven't come across any, although i guess Computex could be the 'proper' launch pad?

According to Google, AMD's explanation of their transistor counts is the only place on the whole web to use the term "de-capacitor cells". They could mean de-coupling, I guess, but to me the only logical way to read "de-capacitor" is that there are parts of the CPU that could potentially be capacitive, and certain transistor masses are required to either safely drain the stored charge in them or prevent them from storing charge in the first place. Sadly, my knowledge of CPU design and lithography is minimal at best, so whether that's also a sensible explanation I have no idea...

The world is not Europe and the US though!!

AMD,sold loads of CPU in Asia,particularly in China which is the biggest PC market in the world.

It seems last September,China alone was taking up 50% of all Llano shipments:

Well everything on a CPU has some capacitance, and usually that is something you try and minimise. There was a time when processors used to bung a bit onto a wire and rely on the capacitance of the wire to hold it until read by the next stage. Works fine, but I thought that fell into disuse as a technique because you can't turn the frequency of the CPU down below some minimum (eg clock stopping for power management or debug) as your data decays and it all falls apart. I think the 6800 did that (the 8 bit one, I don't mean 68k).

Am convinced this is a Chinese whispers problem, someone didn't hear/understand the engineers properly. De-coupling makes more sense, an added register here and there can make a design more robust but adds nothing to the functionality.

Makes sense. There were plenty of posts from people around the world saying how they liked their e350 systems, but *I* couldn't buy one for quite a few months.

Looks like Charlie is off again:

Flat power curve? So adding volts doesn't send temperatures through the roof? That man is such a tease

That's certainly his implication: you can volt it much higher without sending the power usage through the roof - hence higher stable/sustainable clocks. Not sure how that works, as it seems to somewhat defy the laws of physics to me (power draw should scale with the square of voltage), but there you have it.
