Socket 754 vs Socket 939


Recommended Posts

The battle of the Athlon 64's...

I know that Socket 939 is newer and therefore better, but I also know that it's more expensive. What are the advantages to a Socket 939?

Should I bother going that high if I just build new computers from scratch rather than upgrading them?

I read on here somewhere that because the 939's are newer that's what's going to be used for all the newer Athlon chips for a while. If I can get something fast enough anyways on a Socket 754, is it really worth spending the extra money? I don't upgrade my computer components as far as CPU and Motherboard goes, I just get an entire new PC, so getting a 939 for the purpose of upgrading later is kind of pointless.

So do you think I should just stick with 754, or are there other advantages to the 939 that I'm overlooking?

The main difference is Dual Channel Memory as opposed to Single channel on the 754, another big difference is the cache is halved on the 939. Check up on benchmarks to see if Dual Channel is more important than cache. Another major selling point of 939 is future upgradibility.

I suppose the main point is the Memory types. The initial Athlon64's only had support for single channel DDR as opposed to dual channel, and because the memory controller sits on the CPU now rather than on the mobo, to use new memory types that have to put out a new cpu type. I suppose it also stops the newbies from putting the wrong CPU in the wrong board, making the sockets different.

I suppose when they start using DDR2 they'll have to change the CPU size again? Or do the current Socket 939 athlons support DDR2 as well as Dual DDR?
