Intel's New Pentium 4's
(Click here to view the original thread with full colors/images)
Posted by: TotalRecall
Intel debuted it's new line of Northwood Pentium 4 processors a couple days ago. The new processors, running at 2.26GHz, 2.4GHz, and 2.53GHz, have the ability to utilize a 533MHz fsb. These processors will be indicated by a "B" following the title of the chip. To use this new 533MHz bus, Intel has released the 850E chipset. There are many reviews on the web of this duo, and here's a snip from the review at The Tech Report:
Sure enough, the 533MHz bus delivers a good chunk more bandwidth than the "old" 400MHz bus, especially with dual-channel RDRAM. Although the 400MHz bus theoretically was fast enough to accommodate 3.2GB/s, in practice, it was a bottleneck.
Speaking of bottlenecks, the Athlon XP 2100+ delivers almost no more memory bandwidth here, with DDR333 memory on a KT333 chipset, than it did last time out, when we used DDR266 on a KT266A. The limiting factor is clear: The Athlon XP's 266MHz bus. The Athlon XP's bus is now effectively half the speed of Pentium 4's new 533MHz bus (although AMD's bus is probably a little more efficient). Unless and until AMD raises the speed of the Athlon XP's front-side bus, the Athlon XP will be at a disadvantage in scenarios where memory or bus bandwidth is critical.

Does this mean in overall speed of crunching numbers the new Northwood core is faster than AthlonXP? (Until the new Opteron comes out )

It goes beyond that. This is talking memory bandwidth, and what is one operation that hinges largely on memory bandwidth?
Gaming.
I'm considering going Intel with the system I'm going to build this summer, and the new 533 mhz bus chips may be something to look into--or at least wait until they come out so I can get a 400 mhz bus chip at a 5-finger price.

Yes, the new Intel Chips are looking really nice along with the i850E Chipset and the new support for faster RDRAM and I think DDR(Dont remember if there is an i850E with DDR).
But its just a matter of time before AMD Pulls out their big guns and starts firing. Its like a teeter totter effect - AMD releases something that pounds Intel, then Intel releases something that pounds AMD and back and forth. I am suprised though that the AMD T-Bred isnt out yet, it was supposed to be out May 4th I think.
nVidia has also made some bold statements as of late about the i850E chipset: http://www.nvidia.com/view.asp?IO=IO_20020505_8962
Its gonna be a tough decision for me at the begining of next year when I decide to build a top notch PC. I never even considered Intel for it until now.

The top end systems from Intel and AMD are both more than enough to handle anything out there. I think whichever is the best value is what counts IMO.
By the time I may need a speed boost, the Clawhammer will be here. Going to wait and see how it does.

And that is what it will ultimately come down to for me - what is more economical.
That's why I want to wait for these new 533 mhz chips and boards to come out, and see if the existing P4s become more economical.

The clawhammers have an integrated northbridge; the processor has a memory and agp controller built in.
Personally, I want the clawhammer more than what intel is offering, just because it offers something new in terms of advancement, instead of just making existing tech faster.
