I forgot a bit that might help. The system bus is not silent. Based on the chip design, a write to cache may remain within the cache until its page is swapped out (and the entire page is written if marked dirty), or a "write through": both cache and system memory are written at the same time. They use a write buffer either way, which is x-values deep to accomodate for a slow RAM. Occasionally that buffer will be flushed.

Newer designs are amazingly clever to minimize RAM access (read misses, RAM coherency).

I get the general idea - but a few of the details just zinged past the top of my head. Overall, I like this discussion between the two of you.

I tried reading some of the above posts and found myself passed out on the floor under my desk with drool coming out of my mouth.

Back to watching the 3 stooges for me.

As far as I know, the Dothan will go up to 2.0 GHz with the current chipset, but future chipsets will allow for Dothan processors up to 2.4 GHz, which will probably be on-par or better than a P4 3.2 GHz processor.

So... after that discussion between those two that completely went over my head in many aspects, the final verdict is ....

The 2mb L2 cache on Dothan will kick ass, or wont make much of a difference?

It will make a nice difference, but I wouldn't be expecting anything crazy like 2x. A lot of websites like anandtech and toms are going to break down the chip very well. The impact of things like cache aren't as straightforward as a bump in clock rate, so we will have to wait and see what those sites say. Im really looking forward to it.

The 2MB Cache will be good for Mobile Power Users and Mobile Gamers, otherwise the Area-51m would be a better choice. I suppose if you are in the art of OCing such as I am, then the clock speed wouldn't matter as such, as long the BIOS will let you configure FSB speeds. In other words if you overclock then the Dothan kicks ass, if you are really mobile the Dothan is good, if you game at LAN Parties and stay at home then it doesn't affect you.

in regards to performance for 3dgaming,

its really more of the graphics card
rather then cpu power

the graphics card handles 85% of the work

so dothan with its higher x 2 cache of banias and slightly higher clock speeds wont make too much of a diff if ur asking about how it'll fare in gaming

thats really up to the video card again...

and if sentia 2 uses the integrated intel extreme graphics card (crap) u wont be on par with other centrino systems thats hooked up with dedicated ati cards like the 9600 and the new 9700

dothan might be more mobile than banias coz it uses 20w TDP instead of existing banias 25w TDP

but again its not out yet and this is just theoretical speculation

I want to bring in one more factor before we decide how the Dothan will be used.

As we all may or may not know, America is a capitalist country. We want money. Look at Cheney, man has a secret deal with Halliburton and now he drives ferraris. Intel has the option of playing out existing contracts with companies such as dell and alienware, and then discontinuing the current chipset. Then capitalize on the new chipset before releasing their new and improved higher clock speed version of the Dothan, this will swing the market that's already theirs, their way, eliminating competitors such as AMD. If I were the CEO of Intel, and I knew the Dothan was already getting this much publicity, that is exactly what I would do. Who knows, maybe the "delay" wasn't an accident...can you say "free publicity".
