Almost none really, except for the fact that the FX costs about 2½ times as much as the fastest Opteron.
Actually you're wrong...
Pricing The AMD Opteron processor Model 848 will be priced at $3199 in 1,000-unit quantities. The AMD Opteron processor Model 248 is priced at $913 in 1,000-unit quantities and the AMD Opteron processor Model 148 will be priced at $733 in 1,000-unit quantities.
Opteron 248
Jeff, you're the wrong who is wrong, this time anyway! This forum is entitled "What's the difference between the Opteron 14* and an Athlon64. Yeah, the Opteron 200-series are much more expensive than even the Athlon FX, but the 1.8ghz Opteron 144 is only $309 for the retail version, and the retail Athlon FX is going for $776 on newegg. I actually just checked the price on the 2.0ghz Opteron 146 @newegg a couple of days ago, and they had the oem version for $270. Now, it isn't even on their website.
The FX51 runs at 2.2 Ghz... it's faster than the Opteron 146, 246, and 846... I don't care what the price is, or if you can buy any of those in a store, the FX51 is still faster. If you looked at the first link you'd see that the 148, which runs at 2.2 Ghz just like the FX51 is priced at $733 in 1,000-unit quantities from AMD... that doesn't include the markup retailers have to make in order to make a profit.
To answer the question of the origional poster, "What's the difference between an Opteron 14x and Athlon 64 FX?" Pretty much just the name... The A64 FX's have all 3 Hyper Transport links just like the Opteron, the memory controller is dual channel, they use the exact same packaging.
myocardia, Opterons and A64 FX's are basically the same CPU with a different label. So an Opteron at 2.0 Ghz will NOT be faster than an A64 FX at 2.2 Ghz. I think you're just confused about the speeds and the model numbers... so I'll clarify...
Opteron x40 = 1.4 Ghz
Opteron x42 = 1.6 Ghz
Opteron x44 = 1.8 Ghz
Opteron x46 = 2.0 Ghz
Opteron x48 = 2.2 Ghz
Athlon 64 FX51 = 2.2 Ghz
Take a look at this... then tell me if you still think the A64 FX51 is twice as expensive as the fastest Opteron.
