yea, ur right once again, i guess, but not until the nv 40 chip comes, w00t!

the intel has been on the market before the intel but the im not sure amd has made such gains on intel, 40-50%. Dont want to sound like a broken record here but 2.2ghz at 800fsb is dam good compared to pent4 3.2@800fsb. Could someone inform me on hyperthreading, is it like O'cing for pentiums?

im also talking about consumer use, something I an afford, my family has 2 pentium 3's, gonna get my friends pentium 4 1.7 for free, so im not against pentiums. I just tend to lean towards amd for the prices cuz im not running a world simulator here.

I don't need customer support for AMD cuz my mom is a comp. techie :fawk:

Hyper Threading is like haveing 2 cpu's in one.

The AMD Athlon 64 FX 51 is impressive not just becuase it runs 64 bit code (which probably won't take a real foothold until probably 2005) but for how fast it runs 32 bit code. Intel has a 64 bit processor called the Itanium (I think that's the name) for 64 bit servers. Problem is, it supposevly only runs 32 bit code at a Pentium 2 level (not designed for it). The AMD 64 also has the memory controller built into the processor running at processor speeds, rather than behing seperate and only putzing along with the memory like older designed processors. Big onboard cache too. It's not just the same old Athlon XP that runs 64 bit code, it's the newest most powerful chip technology right now.

Hyperthreading isn't quite like having 2 processors, but allowing 1 processor to do two completely different things at one time. For example, if your calculating a floating point number and moving something through a bus, a HT enabled processor can do them at the same time. If you have two operations wanted access to the floating point calculation aspect of the processor, there is no performance benefit, one still has to wait. To really maximize the use of HT processors, the programs that use them must be optimized for them, so some older programs may not run any faster with HT.

I'm still waiting for more info about the P4 extreme edition. I've heard it's a 3.6Ghz P4 with a 2megs of L2 cache. Going to be pricey but should be impressive. Intel isn't being caught with their pants down either, they've got new technologies probably already ready for market. I've read that the nessicary hardware configurations for hyperthreading have been in place in Intel chipset specifications but never actually activated since the Pentium 3's. Intel just never needed a new hot technology for a sales boost so they just waited and attached to the 800 Mhz P4's.

i think the reason he said it's like having dual processors on one chips is that that is how windows recognises it. instaed of one processor you have 2 virtual processors. and as for the performance gain... i ran benchmarks on my P4 3.0G with hyperthreading enabled and disabled and saw at least a 25% increase in performance. that's not too shabby IMO

Which is exactly the reason why I runa dual Xeon setup

And I agree about pants being not down. AMD and Intel are sizing each other out. Throwing jabs here and there and trying to see how the opponents are reacting.

And the bit about the HT is true. I knew about it 6months before it was officially introduced so it was probably capable years before that.

One of my friend that used to work for Intel told me when the P4 was introduced, that was stuff people were working on several years ago :happysad:

The 875 chipsets have Performance Accelleration Technology built into them, which I believe is way to skip a few steps in the pipeline but keep the speed and the MB manufactures found a way to turn it on in the 865 chipest, even though it was never supposed to be an option. I guess Intel hides these little secrets incase they ever need to steal some thunder from someone else.

I was reading about graphics card manufactures like ATI and Nvidea use 3 teams on a 6 month cycle. One is working on the big new technology that about to come out (lets say the 9800 Pro). The next team is working an updated version of that card which will come out 6 months later (9800 XT) and another 6 months to build the next generation of cards will come out. The team that created the 9800 Pro will start working on a 6 month update for the new generation of card that won't be released for a year and a half and the team that built the XT cards are now working on the next next generation of graphics cards that won't be out for 2 years. I though that was rather interesting.

same with Intel. They are developing what we would call next next next next generation processor already.

What we call new is at least 2 generations behind what's already available.

I love how they sometimes show up at IDF and say here is a prototype processor running xGHz and x FSB but it's not stable enough for you to test yet. :rofl:

"Yea, here we have a 10ghz cpu running at 1.5ghz fsb... it's getting like 5,000 FPS in Unreal Tournament.... but only for about 5 mins... then it GPFs'.... it'll be great when it's ready though!!! :eek3: "

serious, amd and intel are jus going at it. andy knows wat he's talking bout

does any1 know how o extract the hl2-anon.tar?
cuz its jus a bunch of rar files that are the same thing.
