Intel 3.40EE & 3.60E - LGA Arrives
MBR writes "MBReview has taken a quick look at Intel's
new high-end LGA775 processors, the 3.40GHz Extreme Edition, and the 3.60GHz
'E,' now known as the 560. They've covered some of the questions about pin
frailty of the new LGA socket, as well as cooling issues that might arise
from these new processors." ("LGA" stands for Land Grid Array, which moves pins from the processor to the socket it sits in.) Update: 06/19 20:50 GMT by T :
Reader Chi-Energy points out that besides the new processor packaging, Intel has also just released its i925X and i915 chipsets, PCI Express and DDR2 DRAM for the desktop, and links to this review showcase with benchmarks at HotHardware.
I'm not as worried about frail pins as I am about the amount of heat these things push out, the size of the new heatsink/fan assemblies, and the noise they put out. I thought Socket 478 processors were hot, but LGA Prescott processors run even hotter, which makes me think Intel has a point when it says we should switch away from the ATX case factor and adopt BTX for Intel chips..
That said, are the Extreme Edition processors still selling for $900 USD a pop? Hardly seems worth the extra money for gaming, although a server that wants to survive Slashdottings could probably use one...
If my answers frighten you, stop asking scary questions.
Apparently the BTX form factor (of which LGA is a part) has been heavily resisted by many Taiwanese chassis, mainboard and heatsink manufacturers.
But what's new here? Word has it that this time round, the Taiwanese heastink, mainboard and PSU manufacturers - and quite a lot of them it would seem - are being rather less than enthusiastic or co-operative, about the sweeping changes and support that Intel is asking, nay demanding, of them.
I'd be interested to see if Intel can actually strong-arm them into it

Yes, it would basically be a widget with pins on both side, one plugging into the mobo and the other into the chip. Then, if you break a pin off, you just replace the cheap adapter. It also means chips would be less susceptible to static shock, since the contacts would not be as exposed.

At high frequencies, the pins on a package aren't really short circuits (ie, zero resistance); they have a capactiance and inductance which mess with the signals. Making removable pins would make this a lot worse.

Yeah..
nothing like a graph that makes a 10% difference look like a 90% gap.

According to Sandpile.org, the 3.4GHz Pentium IV Prescott can use up to 127W, and has a typical power usage of 103W (when browsing the web or reading email).
In my opinion, it is rediculous for a single processor to single-handedly run up your power bill. That's like having two light bulbs on 24/7 (assuming you keep your computer on), not to mention the power needed to cool your PC, let alone your house's air conditioner.
I would take a VIA chip for low-performance stuff, and an Athlon64 for performance computing. support 64-bit software including 64-bit Linux distributions, are faster than Intel's best even running 32-bit software, and they have a maximum power usage of 89W. Because of Cool'n'Quiet mode, they spend most of the time running at 800MHz consuming about 30-35W and generally not requiring a loud and abnoxious cooling fan.
It is actually impressive what the chips can do at 800MHz. You can play a full screen DVD at 1400x1050, and the CPU usage tops out at about 5% (at 800MHz). If, of course, you run something that requires more power, like a video game or a compiler, the processor instantly switches to full speed. Handy, that.

Each time Intel rolls out a new product, an improved version of that product comes about 6 months later that is much better. Early adoption gets you screwed first, quick, and for a higher price. Nothing is better than paying top dollar to be an uncompensated beta tester for the mobo companies.
It seems to me that when Intel develops a product half way through the design process they realize they screwed up but still release the original tech to make cash, then the fixed version of that tech comes out 6-12 months later.
Pentium 60/66 - 1st of the family, used older mobo technology
Celeron 266 - no L2, much better a few months later with the L2
P2 - oops, here is P3, we fixed everything
P4-1.4 - Couldn't beat a P3-800 yet the ram cost 3x more
P4- Needs to be ~1Ghz faster than a P3/PM/AXP/A64 to deliver the same performance (the clock frequency here is a marketing gimmick - and poor design)
Itanium 1 - I-Tanick
I have a feeling a lot of the P4-3.6s are going to fail in the field with stock Intel cooler.
One of the most useful things about the 925 chipset, IMHO, is the interesting possibilities it offers for SATA RAID. Say you want the performance capabilities of RAID 0, but at the same time, you need the redundancy for RAID 1. let's also say that you can only afford two SATA drives.
the intel 925 chipset has native support for a mixed raid, where you can create a raid 0 partiiton across two hard drives, using only part of the hdd capacity on each drive for the raid 0 partition. the rest of the unpartitioned space can be set aside as a raid 1 partition. that way you can install the OS and other non-critical files tha can be lost to the raid 0 partition and get the performance, but if one of the drives fail, you can store your important stuff on the raid 1 partition. I'm trying to find a controller card that will do this functionality, but I can't find anyone that claims to explicitly support it. the only reason I know about the 925 features is I got a chance to play with a pre-production board. definitely a cool feature.
This isn't just some AC's random opinion either. This was the consensus of most of the Taiwan motherboard manufacturers at Computex this year. P4 boards were everywhere, but nobody really expected them to sell. It's like Intel is on a suicide mission to hit the wall at full speed.
They recently has a press release where they stated that they intend to produce processors that consumer 200watts by the end of the year. And that's not peak power as many people naively want to pretend, that's mostly leakage current that is dumped as heat. It has nothing to do with the halt instruction. You can only reduce the power consumption by turning off the machine. They've clearly lost it.

Seen it happen twice, once with a p4 and once with a p/166.
Both times, the chip was just fine afterwards.
if the answer isn't violence, neither is your silence / freedom of expression doesn't make it alright
