bs

Do they actually give you another use of the key?

they ask if you are installing xp on the same system, and then they give you a completely different key.

[hitznrunz]

for me...if i switch video cards..it makes me use the key...i put in a new processor...i need the key...waste of time

Even for OEM versions of XP? I know my OEM version won't accept another valid key unless I get a confirmation number from them.

i bought mine retail and ive gotta call them and they ask why i need another number..i tell them reformat drive and they give me a new number to plug in

actually the extreme edition is Intel's best gaming processor, and it is because of the 2mb of l3 cache. Go look at any gaming benchmarks comparing it to the regular northwoods or prescotts. The extreme edition annihalates them.

That isn't due to extra l1/l2/l3 cache. But due to shreer speed and better architecure of the processor itself. (remember extreme edition=xeon)

[MMmmGood]

Id get the C series ( 512k L2 cache ) as some others have pointed out the difference in performance is negligable and the E series with 1MB L2 cache run a good 5-7C hotter.

I havent had any problems reinstalling with OEM software... even after changing to different motherboards. All you need to do is re-activate over internet or tell them you needed to re-install

Yeah, anytime I need to re-activate due to a re-format or hardware change, I call, give them this phone reference number that appears on the screen, and they give me a number to activate Windows. They don't give you a different key.

lol cache size is the major difference between p4 northwoods and xeons. Architecturally they are very similar if not the same. Think about it, if the extreme edition is so vastly different architecturally from the northwoods, then why can they be used in p4 motherboards? The reason is, that the only difference between extreme edition and regular p4s is cache size.

Doesn't have to be vastly differnt. Just differnt enough to get anouther 5-7% better. Also the 800Mhz FSB over 400Mhz doubles the data bandwidth. Only thing cache is used for is getting files ready that it thinks it will need next so there is less wait. In a FPS it will be accessing the same file nonstop for long periods of time so cache doesn't make as much of a differnce.

(proof is pentium 2 and celeron processor. pentium 2 had cache while celerons did not. Celerons were just as good as the pentium 2 for gaming but video/pictureand office work was very slow on the celeron)

The extreme edition doesnt have a fsb advantage over the northwood. When the EE came out, the northwoods were already at 800mhz fsb. Also, the advantage of cpu cache is that it is a hell of a lot faster than system memory. Therefore the more data that is stored in cache, the faster the cpu can work on the data. Now the Northwoods have 512k l2 cache, while the EEs have 512k l2 + 2mb l3=2.5mb total cache. Less wait = higher frames per seconds


finally, cpu cache is expensive. Intel knew the EE was for gaming, believe me they wouldnt have included an extra 2mb of cache if it wasnt for better gaming performance. thats the reason why the EE's are so expensive. If the cache had nothing to do with better gaming perfomance, they would have left the 2mb cache out to keep production costs and retail prices down.

Hyperthreading actually slows down your computer unless your doing something made to take advantage of it. Which would be video editing, picture editing and thing like that.

Reason is that winxp will install extra drivers so it can use HT.


The pentium 4 extrem edition is really just a hyped up xeon processor with the purpose of trying to take away the athlon 64 on it's debut day.

The extra cache won't help with gaming much but thing like video editing picture modifiying or accessing many files will speed up.

Neither of these statements are even remotely true. There are no additional drivers required for windows to take advantage of hyperthreading. To windows, it just appears as if you have 2 CPUs, which XP supports natively - plain and simple. In fact, as windows is built around the multi-tasking paradigm, there are obvious benefits to having HyperThreading even when applicaitons don't natively support SMP.

The extra cache _always_ helps in memory intesive applications, which very obviously includes games. Gamers are in fact the EE's target audience.

For quantitative proof, look at these benchmarks:

In repsonse to your links taken from one of them.

Conclusions

Certainly if you made it through our 198 benchmarks, you have likely come away with the same feeling that I did, and that is, "Why did I just read all of this?" Of course in my case it was, "Why did I spend all week hovering over motherboards to find out that this launch is basically a stagnant move for Intel?" Well, that might be how it seems at first, but let's look at a few things independently.

Then it goes on to say that the pentium 4 will be better because of PCI-E DDR2 new socket types and other crap.

As to to hyper threading, if windows detects hyper threading is on during the install it installs extra drivers during the install to take advanatage of it. Unless your doing something made to take advantage of it or you multitask compatible programs it's 5-7% slower.

Using Programs That Help You to Help Yourself to HT

In summary, do not expect HT to change your life that much unless you use a computationally intensive program such as a video editing or a high-end game designed to really take advantage of HT benefits, almost all of which are not yet commercially available. The applications available today that take advantage of HT were inadvertently written for the end user. That is because software such as Adobe PhotoShop and Windows Media Decoder offered multithreading for debugging purposes prior to their commercial launch.

Conclusion

Applications already optimized for HyperThreading see performance gains from the use of two physical CPUs. In view of system costs, it is therefore worthwhile for users to go with a Dual Xeon as their next system if most of their time is spent rendering or encoding.

http://www6.tomshardware.com/cpu/20040322/prescott-25.html

Conclusion

The new Prescott at 3.4 GHz behaves pretty much like the 3.2 GHz version. It comes with slightly faster performance at consistent thermal specifications. And once again it is not clearly faster than a Pentium 4 Northwood at the same clock speed, while there are a few applications such as Pinnacle Studio or MPEG 4 encoding with XMPEG/DivX where the Prescott 3.4 GHz even outperforms the P4 Extreme Edition at 3.4 GHz. On the other hand, in Cool Edit Pro 2.1, it is even slower than Northwood 2.8 GHz.

Hyper threading is just a marketing scheme just as was the p4 when it first came out. (p4 was actually slower than p3 of the same speed)
And extreme edition is just anouther marketing scheme so they can keep pushing the same product out for the same price or increased price.
