No, 0.5W is not possible. Just see the heatsink of a north bridge. Memory use dam heavy I/O drivers to get maximum transfert speed while driving high capacitive lines. And this is without take in account the internel logic.
I find the datasheet of the 915PL north bridge (without the integrated graphic) http://www.intel.co.jp/design/chipsets/datashts/30 1467.htm and in page 257 you can find the power characteristics:
Core at 1.5V discret take 7.7A => 11.5W
I don't count VTT bus and others since Turion have no PCI-E but have HyperTransport. But in next page you have the DDR table:
DDR interface at 2.6V take 4.1A => 10.6W
So the memory subsystem on intel can burn as high as 22W! Even if this number are two time too high, this put Intel to 27W + 11W = 38W at the minimum.
The article say "tri-LED DLP", not three DLP chip. I suspect that there use only one DLP and use 3 set of LEDs, to have the RGB colors without the use of a color whell. The advantage is that make a full static mechanic system. Other advantage is that there can pulse each set of LEDs with havy current as there duty cycle is 1/3. So there is more power light without destruct the LEDS. This trick is also used into each IR remote control. Maybe there is possibility to use 6 set of LEDs to take even more power and buitfull colors...
Now M$ is certain that some big US pharma will stay away from OSS...

No. This is not a typo.

FBGA is very common for small processors and chipset. FPGA is not so much used but for old CPU as now Intel uses LGA and AMD uses uOPGA
No, mysql is just a dangerouse code for your data. Just list how many filedescriptors mysql keep open on all the tables it uses. For exemple on my server now there is 148 filesdescriptors open from mysql, majority of them are on tables.
Now if you look at postgresql process, you see only a few pipes and socket and only two logs files open, no tables. Even if you make some big query, is not easy to see filedescriptors open on table from postgresql. Postgresql take care to protect at most as possible your data.
The probability to trash a posgresql table is not null, but the window is very thin. Mysql instead manage to have almost 100% probability to trash your data. What happens to my serveur data is just the consequence of the design of the code running on it.
Just to inform you, a few weeks ago the server I manage crashed despit the mirroring (one disk failed, and the ext3 filesystem has corrupted entry).
The machine have mysql and postgresql databases. result is simple: almost all mysql users have trashed tables, absolutly _NO_ users have any glitch with postgresql. If your data have any values, forget mysql, only use postgresql. Periode.
For me, data integrity is the highest priority, all other aspects are just cosmetic.
Before last year I owned a CRT 21" (real 20") Sony F500 that have been CHF 2400.-- at buy time, 4 years ago. This was one of the top most clear and precise monitor you can get in normal shop at this time, providing 1600x1200 at 85Hz with linear and superbe colors.
When it break, I discovered that LCD 20" 1600x1200 Acer AL2021 is only CHF 1300.--, almost half the price of the CRT before. I immediately buy it and I found that the product is great fot that price, even if the frequency is only 60Hz and the colors not completely linear (you can see that while watching movies). But the sharp, contrast and stability is far superior. Not mention to the space saved on my desktop!
The probleme is that 20" LCD TV you can buy now cost CHF 1300.-- (same as a 20" LCD monitor) but for only 1024x768 at 50Hz!!! This is just crap as you lost the possibility to get good picture while using it for other thing than TV.
A better solution if to buy a 20" LCD monitor and a TV tunner card for a old PC without fan booting a USB flash device. I sucessfully use a quiet, NFS rooted PC for that.
From the article I found very weak the conclusion that this brain section act like a cache. This can be a multiplexer that connect a processing section the the memory section. Or more simply registers that hold intermediate informations.
All the 3 systems have in common that there are build with memory cells, but there are different in terms of the way the memory are used and the associativity. Registers and caches hold encoded informations; multiplexer don't care of the encoding. registers don't have any associativity between a tag and tne information stored, only cache have that.
All tree systems generate heat and consum power that the brain camera see. Really, I see nothing that assert this is a cache.
Sound like the author want to use high-tech buzz word, without any prof.
I agree about CMPXCHG16B. AMD should have including it as it seem to help creating fast, explicit lock free algo. But to be atomic the CMPXCHG16B opcodes have to do bus locking. Because of that this don't make a hug difference at the end: The AMD implementation will have more opcodes but in a path where the bus locking is the slowest thing anyway...
No! You are wrong, x86-64 and IA32-e both uses 32-bits operands. Other way there will not be compatible!
For AMD see the table 1.1 "Operating modes" page 43 of http://www.amd.com/us-en/assets/content_type/white _papers_and_tech_docs/24592.pdf
For Intel see the table 1.1 "IA32-e modes" page 18 of http://developer.intel.com/technology/64bitextensi ons/30083401.pdf
(I dont know why slashdot add sometimes a space in the URL, it's not in the original)
The CMPXCHG16B example just show that Intel continue there nasty game of adding opcode in a way that nobody can use it because thre need to run on AND chip too.
Yes REX prefix byte is a small change in the instruction set, but a very nice one: it allow to extends the architecture to 64 bits (more longer registers, more addresses, etc...) while permit to execute IA32 userland code without problems.
The most nice part it that the change do more cleaning that hacking: Intel have a long history of adding new opcodes to IA32, but almost no one use it because binary programs have to run on all IA32 chips including the older one. So now the difference between older and new IA32 chips is so big that for time critical functions, programmers have to test the capability of the chip and to dynamicaly branche to a dedicated functions optimized for that chip. x86-64 make a hug reset to this entropy. This don't stop the process as new opcodes will exists in the futur, but at least it voids the last 10 years or so ugly hacks to the IA32.
In a wonderfull world, where all uses Debian source package and recompile it for each of his machines, the binary compatibility problem will be less important. But this even don't solve the problem, as the detection and specialization to a dedicated chip will be done while compiling.
The lesson is that it is not supportable to indefinitely add hack to an architecture. Sometimes it better to make a new backward compatible architecture. I doubt that 128bits computing will be the next thing that will trigg an architecture change. But without doubt architectur change will happens again in the futur to clean the older one and enable new capability.
And at this time the market will certainely follow the proposition that will have the bigger performance and smallest change ratio. This is exactly why IA64 is dead and x86-64 shine, forcing Intel to copy it and rename it IA32-e...
I would like to see how SCO can charge for code that are not in the binary image. Embedded system like Tivo have very little probability to compile NUMA or RCU code. This have no sense. Remember that SCO licence is for binary use (to be compilant with the GPL, as there say...).
SCO is crasy if there expect to charge for somthing that don't even exists!
If it's not 2.3.99, take 2.3.43 or 2.3.18... If problematic code exists, it have been introduced in a know version of linux, take version-1 and merge the evolution and fix.
SCO case is about introduction of code into Linux, not about Linux having the same functionality as sysV.
In a small country like Switzerland, media play a far less role because the normal relation of each people quickly corver a appreciable part of the whole activity. This become especially true when a probleme occure because everybody talk about it. Everybody here play the game because everybody have the right to change the law. We are still the only direct democratie in the world. I play the game and I pretend to have some experiences of what is the difference of the stuff on the TV or online compared to what really happens.
In USA there is I think two big barriers to let the people fell what is the reality. First is that USA is so big that the normal relation of people can't extract valuable opignion of the whole country. This let the media play a overratted role, and since media is more controllable that each people directly, lobby use them to put some artificial stuff. Second the politique activity and possibility of a american is so decoupled of the process of makeing the law that people are not responsible, but "one in the masse".

The "iraqi super cannon" was a hoax to break some chance to get contract for some EU company. The end of the studie show that the material cannot even be modified to make a cannon. I agree that this can be used to other military purpose, but nor the studie, nor the ONU inspectors, nor the US army can find any "suped-lethal-massive-weapon-ready-in-hours" or others imaginative devices that US and UK secret services known so well (especially there location...).
And since you assert that the UK make the probleme, did you remember that this is your closest allie in the Iraq ware?
And for the final, I live in Switzerland, who as you probably known invade almost every contry in the world, take black peopole to make hard work, finance the most powerfull army, and attack every contry that have petrol... Realy, it seem that your last justification is based on the fact that everybody is agressive as you. Check a second time!
Clean up? Are you thinking US have resolved the vietnam, afganistan and iraq problem? Try to live in one of this contry a whole yare!
US create the afganistan problem by provids ultra-fanatic material agains the URSS. You have to assume now.
You say that France and Germany sell military technology secrets and weapons, but are you able to say a single example? No one have found this kind of secrets and weapons for months. Do you realise that you say is completely wrong? Did you understand the reality?
European are not against USA. It's a idea from USA just because you do not see the reality.
If you take a look at the real number you can found on the web (many good URL are in this thread) you will quickly understand that the European countrys together spends far more monney on aid to other nations (in total $) than the USA.
USA use a very wrong way to make a secure world. There think that there are the only country to have the "right" to be "free". All others have to be under there controls.

Still, as you say 27+6=33W and this is very near 35W . We will see if Intel need only 2W to add the 64 bits feature to an old P3 desing...
No, 0.5W is not possible. Just see the heatsink of a north bridge. Memory use dam heavy I/O drivers to get maximum transfert speed while driving high capacitive lines. And this is without take in account the internel logic.

So the memory subsystem on intel can burn as high as 22W! Even if this number are two time too high, this put Intel to 27W + 11W = 38W at the minimum.
Now AMD with 35W look far better...
AMD wattage includs the memory controller. Do anyone know how much watt take the Intel memory controller (without the integrated graphic) ?
