Socket A --> Socket 754 --> Socket 939
 
Hey all, question. Is that how the 'order of power' goes with CPU's these days (see flowchart thingy in title)

So, for example, would a Socket 754 AMD 64 2800 be faster than my Socket A AMD XP 2800 and by how much?

Also, can you tell me the increase in speed i would see from the following upgrades. Trying to balance cost with performance u see:

AMD XP 2800 -> 1) AMD Athlon 64 3000 Newcastle 130nm (754)
2) AMD Athlon 64 3200 Newcastle 130nm (754)

AMD XP 2800 -> 3) AMD Athlon 64 3000+ Winchester 90nm (939)
4) AMD Athlon 64 3200+ Winchester 90nm (939)

So, please advise me on what kind of performance the upgrades above will give me compared to my Xp 2800. Either be technical or just say "Thats gonna be ****ing faster than your current CPU"

For example:

1) the AMD 64 3000 socket 754 is a pretty sweet card, you would see maybe a <insert fps number here> increase in games. Programs would run a lot faster too!

well yes, an Athlon 64 2800 in socket 754 will be faster than your socket A XP2800+. and you will notice the difference.

the difference between the 754 and 939 socket A64's is minimal, the reason people get 939 over 754 is because it supports dual channel ram, is going to be used for a long time still, and all the new AMD cores will be released on 939 and not 754.

i would say that the best bang for buck cpu out of the ones you listed would be the 3000+ winchester.

To give you a bit of a idea of what the differences are:

great stuff :D

cheers

Ok, as i am strapped for cash right now i'm just gonna buy a socket 754 MOBO and a 3000+ or 3200+ CPU. Once again i find myself asking, can i add PC 2700 RAM to most 754 mobos without any real performance loss?

that is a nice little chart!

Diabetic, i recommend getting socket 939 eminently! Socket 754 only good use is mobiles. Socket 754 processors have 1.6ghz HTT. Socket 939 processors have 2.0ghz HTT. Thats an 400mhz increase. Another good fact about 939, is it has REAL dual channel RAM. Normal dual channel RAM, is regulated through your mobo. But socket 939 dual channel RAM, is with the cpu. 939 Processors are built with a DDR Channel inside the the very processor. 939 is the way to go man

There is no reason to get 754 if u can get 939.

'nuff said.

Diabetic 04-24-2005 12:46 PM

but i'm trying to be..... ahh **** it. I'll get 939, still, someone answer me this. Will sticking PC2700 ram in the mobo have any negative effects? Will it work? Cause i don't have enough money to buy RAM, mobo AND CPU. Just enough for MOBO and CPU (notice the word 'just')

gaara 04-24-2005 01:08 PM

Yes, it will. The Athlon 64 HTT speed is 200MHz, the RAM you are trying to put in it runs at 166MHz. As a rule, RAM speed must match the HTT speed for the best performance results. Get PC3200 RAM, you'll thank yourself later.

Yeah it will, but your ram wont effect the HTT I believe, as you still have 200 FSB (on athlon) since the memory controller is built into the CPU and you still have your blazing fast 1000mhz HTT

For therotical things about SKT 939 with ram, with PC2700 in single channel you get 2.7 GIG bandwidth, with 3200 in single channel you get 3.2 gig

Dual channel actually doubles your bandwidth, so 4.6 with 2700 dual channel, 6.4 single channel.

Actually though with 3200 ram in dual channel with good timings the record is 5.9 gig not 6.4.

Here's a few more results for examples, take time to laugh at DDR2
