The Lineup - Athlon 64 X2

As we mentioned earlier, the Athlon 64 X2 isn't going to be officially launched until June.  While AMD is purposefully vague in their discussion of availability, it looks like their plans are for system builders and OEMs to offer Athlon 64 X2 systems in Q3 of this year and for retail availability to be in Q4 of this year. 

For AMD, the Athlon 64 4000+ was the last single core Athlon 64 that they will make; all model numbers after 4000+ will be dual core Athlon 64 X2s.  Starting at 4200+ and going up to 4800+, the Athlon 64 X2 continues AMD's trend of basing model numbers on clock speeds and cache sizes.  You can see the breakdown below:

For starters, the Athlon 64 X2's clock speeds aren't that low compared to the current single-core Athlon 64s.  The top of the line Athlon 64 FX-55 runs at 2.6GHz, only 200MHz faster than the Athlon 64 X2 4800+.  This is in stark contrast to Intel's desktop dual core offerings, which run between 2.8 and 3.2GHz, a full 600MHz drop from their fastest single core CPU. 

The other major difference between AMD and Intel's dual core desktop approach is in pricing. Let's take a look at the cost per core of the Athlon 64 X2:

We see that AMD's desktop pricing is much more reasonable than their dual core Opteron pricing, but then again, also remember that their desktop CPUs won't be in volume until later this year.  The second core never costs more than the first one, which is honestly the only way you can ensure good desktop adoption rates. 

That being said, let's compare it to Intel's pricing:

Because Intel is only shipping lower clocked dual core CPUs, Intel's chip prices are much lower - not to mention that Intel's manufacturing abilities far exceed those of AMD.  Percentage-wise, the Pentium D 3.2 commands a high premium for that second core, but the prices are overall quite reasonable.  The fastest Pentium D is still cheaper than the slowest Athlon 64 X2 4200+, and the slowest Pentium D is ridiculously cheap compared to AMD's dual core offerings. 

AMD's answer to Intel's aggressive pricing is two-fold. Eventually, all of AMD's CPUs will be dual core, and thus, prices will be driven back down to single core levels. But for now, AMD feels confident enough that their single core CPUs are fast enough to compete with Intel's low clocked Pentium Ds.  We put that exact thinking to the test in Part II of our Intel dual core preview and concluded that it really depends on what type of a user you are. If you tend to multitask a lot or run a lot of multithreaded applications, then a slower Intel dual core is what you need; otherwise, a faster single core AMD is your best bet.

    i think what #130 was saying was that: from top to bottom, AMD's offerings are really good...if you want the best "bang for the buck" the 3400+ or whatever, or a 3000+ winnie OC'd will provide you with the best performance per dollar you spend...EVEN against the X2's.

    On the other hand if cost is not an issue, an X2 4400+ provides extremely good performance for people willing to pay the $500 premium.

    Zebo's point is in direct response to your point, which is AMD "STILL" has the best bang for the buck, not intel.

    or maybe YOU missed the logic? LOL

    "Intel is just lucky a 3400+ new castle wasn't in that test suite. It's would win the majority of tests over an 830!! and it's still cheaper. Or did you miss this chart? LOL"

    Why not just admit it. AMD's DC is about 10-20% faster while costing 80-100% more.

    Even if the 3400+ is added, that comparison is moot since if you compare the score of that to the price of AMD's own DC - the price performance ratio is stagerrring? Or did you miss that logic?

    Anyways did you miss the part that even AMD DC was being beaten by their own single core.

    Next.

    "The Athlon 64 4000+ was the last single core member of the Athlon 64 line.
    The Athlon 64 FX will continue as a single core CPU line, with the FX-57 (2.8GHz) due out later this year."

    Where did you get this info anand, i am not sure if an Athlon64 X2 4400+ could not coexist with a Athlon64 4400+. If this is the last 4000+ than i must say gee thats too bad....

    Techreports review is better for you. 64-bit OS, 64-bit apps when possible, no mystery unreproducable benchmarks like Anand's database stuff.

    MPE BS, Intel is just lucky a 3400+ new castle wasn't in that test suite. It's would win the majority of tests over an 830!! and it's still cheaper. Or did you miss this chart? LOL

    Intels DC chips can hardy compete with AMDs single core offerings. Side by side both DC it's a joke.

    So ya, AMD still has the "best bang for the buck" top end to bottom end. And they a far on top of the mountain.

    Isn't the shoe on the other foot?

    For several years now, so many touted AMD's cheaper price and competative pricing.

    Now with Pentium4 D, especially with the 3GHz model, you get half the price of the cheapest X2 while probably at best 20% lower performance?

    What happened here?

    Now P4D 3GHz model is the best bang for the buck and not the AMD offering. This is a complete reversal of what a lot of AMD supporters have been touting?

    #125 Yeah, good point.

    Compare:
    A. singletreaded 32-bit app on a singlecore
    B. multi-threaded 64-bit app on a dualcore
    Considering that multithreaded apps already see such large gains on dualcores, going 64-bit too could well mean a more than 100% improvement from A to B.

    But of course, NO ONE needs dual core, 64-bit and +4GB memory in the next 5-10 years :P

    The ball now lies with MS and (Linux) app developpers to write more stuff in multithreaded 64-bit code. From what I hear and read it is not so much the 64-bit part as it is the threading that is a real challenge, even for veterans.

    Visual, On P.12 I was referring to the closest Xeon competitor to the 252s which is the Quad Xeon 3.6 GHz 667 MHz FSB.

    Does that make any more sense?

    jvarszegi, the actual stored procs are not prefixed with "sp_", we just used that as part of the "analogy" to the real system.

    One could also argue that we did not prefix the analogy example with the object owner either which also incurs a cache miss.

    Honestly, I have never quantified the expense of the sp_ prefix or the object owner.

    Where are the dual-core Windows x64 and Linux x64 benchmarks?? That's what I really want to see.
