Cool AMD Athlon 64 FX-51

what is the Atjlon 64 FX-51 CPU? i just heard about it a few days ago. its more expensive than the 64 3200+ so is it newer and better??

HAL9000 had a nice post awhile ago about different Intel chips (Link), could someone post something like that about AMD chips? it seems like AMD has about 500 different chips! lol

Celerons... all of them are on a 400Mhz FSB and currently goes up to 2.8Ghz... all have a 128k cache

P4 400Mhz FSB processors.... available up to 2.8Ghz. Willamette cores with 256k cache, Northwood cores with 512k cache.

P4 533Mhz FSB processors available up to 3.06Ghz all with 512k cache. Only the 3.06 has hyperthreading

P4 800Mhz FSB processors available in 200Mhz increments from 2.4Ghz to 3.2Ghz all with 512k cache... all with hyperthreading.

P4 3.2Ghz EE. Extreme Edition P4... 800Mhz FSB, 512k L2 cache, 2MB L3 cache, hyperthreading... essentially a Xeon with an 800Mhz FSB in P4 packaging.

the fx is the new amd chip
lvl 3 cache added and fsb goes up the 1600 (200Xtoo many for me to count )

fx are opterons in a desktop packaging... just like the ee is a xeon. they perform better and can be oced higher.

they use registered ram on the present socket but as soon as 939 is here they won't be using reg ram anymore

the fx-53 is awaited by the end of this week btw

The FX chips also support Dual Channel DDR, which the regular Athlon 64s do not.

They are also multipllier unlocked, not that they can OC very high.

I know my AMD athlon 2400 was unlocked... somehow... but I never wanted to overclock it yet... Don't need to until my friend upgrades his dell.. Then I'll show off.... haha..

Also, the AMD athlon fx runs at 2.2 ghz currently and is pretty much an opteron for us regular comp users. The motherboard support is going up, but before anything happens, they change the socket to ONE less pin.. thats funny

Im assuming you dont care for anything before the athlon XP.

The XP 1500 through the 2400, as well as the 2600 non barton version, all run on a FSB of 266.
the 2500 barton, 2600 barton, and all the Athlon XP's after that(except the 2700 non barton) run at 333 FSB until the XP 3000, which runs at 400 fsb, as well as the 3200

for reference the Lowest athlon XP, the 1500, runs at 1.33 ghz, the 1800 at 1.53, the 2200 at 1.8, the 2500 1.83, the 2800 2.083, and the 3200 2.2.

the 3200 has 128k L1 cache, and 512 k L2 cache
same with the 3000 and 2800
the 2700 (non barton) has 128k L1 cache, and 256 L2 cache.
the 2600 barton uses 128k L1 cache, and 512 L2 cache
2500 is same as 2600
the 2400 (everything after this is not Barton) uses 128k L1 cache, 256 L2

the 1500 through the 2400 are all the same.

is this the info you wanted?

there is a 3000 with 400fsb? I was thinking they only did it with 333fsb so it's 166 X 13, what is the 400fsb multi? 11?

Wait, doesnt the Athlon FX-64 have something called quad-pumping? I read that the Athlon FX, and the 3200+ have this meaning they only have a 400Mhz FSB, but it is multiplied by the speed of the ram. ex. 400Mhz FSB x DDR3200, or 400Mhz= 1600, right or am I wrong? correct me if I am wrong.

Intel have quad pumping, not AMD.

To answer your very first question, the FX line is going to be the big bucks of 64bit processors where the others are going to be specialized more for the general buyer. A good analogy is the comparison between celeron and pentium.
