A64 3500+ has Dual Channel Memory Controller, A64 3400+ doesn't. AMD wants us to think that dual channel memory controller can compensate the loss of ~9% clock speed and may even make the processor little faster. But in really 2.4 GHz 3400+ is faster than 2.2 GHz 3500+ in almost all apps.
A64 3400+ (2.4 GHz) is the best performing CPU you can buy at a reasonanble price. There's only four A64, which are faster than 3400+. Among these four, 3700+, 3800+, 4000+ are slightly faster than 3400+, but cost much more. A64 FX55, which is clocked at 2.6 GHz is somewhat faster than 3400+, but you can build a decent performing inexpensive PC with the price of A64 FX55.

Although I am interested in seeing benchmarks between S939 and S754 of same clock speed (not same XX00+ rating) to see what impact dual channel memory does have over single channel... anyone know of one?
In just two days, tomorrow will be yesterday.
Agreed. However, IMO it’s a virtual tie. By the CPU charts they’re tied in OGL and video benchmarks, the 3500 takes 3D Marks and memory synthetics, while the 3400 takes Unreal, Far Cry, Audio and CPU synthetics. 100 points is wish-wash in AMD speak.

Well......... 6 actually,if you count the fx-51, fx-53 and the FX-55 chips among the faster 64's. The fx-51 rates nearly the same as the 3400+. There is the FX-53(<b>$762</b>) which is identical in clock speed and L2 cache as the 3700+(<b>$429</b>) and the 3800+(<b>$589</b>). When they post benchmark results, all three of these are in very tight sscore groupings. The 754 socket 3700+ actually beats the other 2 in some game benchies.
The common denominator here between the 3700+ and the 3400+(<b>$199</b>) is the socket. socket 754 chips just plain perform better than their 939 bretheren of the same price range. The 3200+(<b>$199</b>)939 socket costs the same and doesn't perform as well as the 3400+. The 3400+ is a great chip and you could do worse than having this one. The dual channel memory and PCI-E technology is not quite all it's cracked up to be just yet and the 754 still rules for the money.
