Intel Core 2 Extreme QX6700 Reviews 197
An anonymous reader writes, "The first reviews of Intel's new quad-core Core 2 Extreme QX6700 have emerged this morning and opinion is mixed. TrustedReviews were blunt: 'There is nothing new on display here. Very few people will need quad cores...' while Tech Report think 'many owners of this beast may be stuck waiting for new applications to arrive that use it to its fullest ability.' The boys at bit-tech managed to overclock to 3.47GHz and found the first killer application: quad-core support in the Source Engine! Nice!"

5-6 years is ages in computer technology. Maybe now 200GB disks are entry level, and I indeed have two 200GB disks here and 320GB external disk, but if I go back 15 years ago, I'd still buy myself a 20MB Seagate for my IBM PC and probably never find what to fill it up with.

On a quad core system, 40% CPU = 1 core pegged (100%) and a second core at 60%. In other words, you simply didn't have enough going on concurrently. The reason why you didn't see a performance boost over that of a dual core system is because you never even pegged two cores, let alone four. This is exactly why most people will get zero (or nearly) benefit from a four core system. Heck, most games are still single threaded which means on dual core

I work for a company that runs their application in a clustered windows shop. The cluster is active passive for highest availability. Microsoft and "high availability" is the greatest contradiction. Ever.
Every once in a while, we max the two dual-cores out on the server. So a quad core should help us avoid those maxed-out periods.
I don't know anything about windows cluster, is there a way to add more servers as processing power in this environment?

For general computing, I'd rather have a quad-core 500 MHz processor than a single-core 2 GHz one. It'd run cooler and be more responsive, even though the peak performance would be lower.
Ideally I'd like a computer with a display engine running an OpenGL-based remote display server, and one or more compute engines... and maybe even a separate processor for the file system with its own battery-backed RAM. Not just a RAID controller, a NAS box inside the computer.

I don't think you do. A java application here chokes on the 4 x 400MHz sparc (about a minute to render the menubar!) and runs well on the older 1.8GHz AMD systems. Memory is not an issue on both, and is far more plentiful on the Sun anyway. Dual or quad core or 1GHz vs 2GHz is a different story but I think 500MHz is too slow for far too many things now that don't have more than one process or thread.

I know the sparc is a bloody anemic processor, thanks to its bizarre stack discipline, but I had no idea that a quad 400 MHz Sparc was worse than the 33 MHz 68000 in my Clie, or the 166 MHz Pentium (not III, or II, or even MMX) in my Toshiba Libretto!

Same thing that a battery-backed cache on a RAID controller does, except in spades. The battery backed cache gives you block integrity even if the system loses power, so you can do write-back instead of write-through caching. This gives you file system integrity even if the system loses power or the OS crashes. Which means you can do more buffering and smarter buffering.

The idea with Fortran (and presumably with these new languages) is that it's higher level than something like C. You need higher level structures in order to represent parallel vs. sequential operations in many cases. For example, if you're writing a parallelizable operation as a C-style sequential loop, you're actively prohibiting the compiler's attempts

Run "top" and see. Usually there's maybe one process that's somewhat CPU bound, and everything else is in waitstate for one thing or another.
As developers start writing CPU intensive code to be threaded and run on multiple processors, having many cores is going to become a wonderful thing. But at the moment, most systems have one, or maybe two CPU bound processes on average, and most cores will sit idle.
