Please could someone give me an idea of how fast an AMD 64 3000+ mobile processor is? How much quicker is it than the 2800+ mobile processor? And can it be compared to a centrino 1.6GHz (With 2MB L2 Cache)?

Thanks guys.
Greg

It will be a fair bit better than the centrino, The 3000 will be only slightly faster than the 2800.

The mobile processors are popular for overclockers who pop them into "normal" PC's and take advantage of their low power and resulting lower temperatures when they overclock them to the hilt, often with water cooling solutions. In theory, the mobile CPU's should remain stable at higher overclock speeds, though I haven't tried it myself.

Currently, I run an AMD XP2800+ "Thorton core" CPU overclocked to perform like an XP3200+. It's now summer here and so far it's been fine on standard fan and heatsink.

Centrinos don't compare to 64 processors, they are different leagues. The 64 is far more faster than the Centrino.

My system:Intel Q6600@3.6GHz, Corsair XMS2 4GB DDR2-6400 (4-4-4-12-1T) , Sapphire 7850 OC 2BG 920/5000, X-Fi Fatality, Corsair AX 750, 7 Pro x64

Thanks for that guys, all I really needed to know! Grin

What can the AMD 64 2800+ and 3000+ be compared to then? I have absolutely no idea of the speed of the AMD 64 processors, or any AMD processors for that matter.

Cheers,
Greg

AMD CPU's are named after the Pentium CPU performance equivalency. (AMD don't claim this, but that's the way it is.)

So, an AMD XP3000+ is roughly equivalent in performance to an Intel P4 3000 hertz, (3.0 gigahertz), CPU.

AMD 64 bit CPU's use 64 bit technology as opposed to 32 bit, the current computing standard.

I don't think their is much of an advantage in the CPU power between, say, a 32 bit AMD 2800+ or it's 64 bit counterpart. The AMD naming convention takes the relative difference between the two technologies into account when they name the CPU. In fact, the 64 bit version is actually slower in it's frequency than a 32 bit equivalent.

AMD had difficulty raising the performance of their CPU's by using raw speed increases to their CPU's because of physical technological barriers. They simply hit a wall with the amount of layers of silicon they could use in their design. They instead used different technologies to improve the CPU's performance without having to ramp up the actual speed of the CPU.

Intel's CPU design was more readily adapted to raw speed increase and set the standard for CPU power by simply stating it's oscillation speed in hertz in it's naming convention.

Unfortunately for the end user, CPU naming is becoming more cryptic with the variety of CPU's now on offer. (A clear attempt to baffle us all with their technology! Wink

)

The end result of all this is that it takes a geek's dedication to sort the whole mess out so we can make a valid and wise purchase decision. The "industry" relies on the ignorance of the masses to "flog off" all the cheaper and nastier variants of their products.

Let the buyer beware.

I agree with Congo.... So does a 3800+ Run as fast as a P4 3.8Ghz? So, looking in the OC UK catalogue, I have found a 'AMD Athlon 64 3800 Newcastle 130nm (Socket 939)' and a 'Intel Pentium 4 570 "LGA775 Prescott" 3.8GHz (800FSB)'. The AMD 64 is £431.81 and the P4 is £469.94. Personally I would buy the AMD 64, but which would eb the faster for simming?

Thanks Congo. Helped a lot. But how much faster is a 64 processor than a 32 processor?

Here is a bench of my CPU which is an AMD64 3500 not overclocked whilst doing this bench test. As you can see its the same as a P4 3.4GHz in the Drystone test.

Not sure how much advantage 64bit has right now but as software starts to use more 64bit technology things will only get faster on 64bit systems. I will say my system is megga fast and I really like it Grin

Its the HyperThread Technology in the 64bit CPU's that helps the most I think. Like P4's that have an FSB of 800MHz. HT on AMD64 does the same thing. In Theory my FSB is 1000MHz as my HT value is set to 5 in BIOS hence 5 X 200FSB of the ram = 1000MHz Grin

This is why things get fast!!

AMD64 3500+ @ 2200MHz 400FSB&&MSI K8N Neo 2 mobo nForce3 chipset&&1gig Corsair XMS PC3200 timings @ 10.2.2.2 &&XFX 6800 Ultra @ 450/1200&&80gig HDD&&Loadsa fans!!!
