AMD questions

[willirob]

Hi, looking to buy new AMD system - a bit confused

Whats the actual diff between the AMD X2 3800+ and 5000+

Processor: AMD Athlon 64 X2 Dual-core
Model Number: 3800+
Frequency (MHz): 2000
L2 Cache Size: 512KB x2
Socket: Socket 939
Stepping: E4
Manufacturing Tech (CMOS): 90nm SOI
Wattage (W): 89
System Bus (MHz): 2000

and

Processor: AMD Athlon 64
Model Number: 5000+
Frequency (MHz): 2600
L2 Cache Size: 512KB x2
Socket: Socket AM2
Stepping: F2
Manufacturing Tech (CMOS): 90nm SOI
Wattage (W): 89
System Bus (MHz): 2000

Looks like just the clock speed (600MHz) and stepping

Could someone please explain and does this justify the price diff

THanks

Those things are now ancient.
Get yourself a Intel Core 2 Duo E6600.
Their almost half the price of the AMD, and is currently the fastest processors around. (Yes, even faster than the amd FX62)

Core 2 Duo maims so many things out there. The E6800 is the craziest thing I've seen thus far. That E6600 will kill those AMD's. It seems to be almost on a par with the FX62. Certain things it beats the FX62 at, other things it doesn't. Really good value for money though

Willirob, the 5000+ is an AM2 CPU which means you need a socket 940 mobo for it. The 3800+ is a dual core CPU still based on socket 939.

If you have a socket 939 mobo, you might want to consider the 4800+, its 2,4ghz and you can get it for as little as R2600 brand new

 

[Syzygy78]

that AMD 4800+ is also dual core btw

 

[DearHeart]

If price didn't matter then I will go for the Intel Core 2 Duo, but the 6400 sells for R2000 and the 6600 for R3000, while the AMD Athlon 64 X2 3800 is R1215 and the AMD Athlon 64 X2 4200 is R1500.

 

[MrE]

forget the 4200+,
rather the 3800+ and overclock a little to 4200+ or more,
or
go for the 4400+ which has 1mb L2 cache.
and then you can overclock to 4800+ or above

 

[DearHeart]

Does anyone know of a benchmark between the Intel 6400 and the AMD 4400 since they both sell for +-R2000? The benchmarks on Toms hardware only show the higher end chips. Is it only in SA that price matters?

 

[ShockG]

The 6400 is faster. Given the option I'd definately tyake the 6400, but get a proper mobo cause it has a low multiplier so a board that'll only do 300Mhz is no good!

I hate the fact that you have to get a new mobo for each new Intel CPU that gets released, whereas for AMD you only need one board that will last for aaages to come.

AMD forever!

Not really, AM2 is not 4x4 compatible, nor is it K8L compatible (which is due next year) so chances are you'll be changinf the AM2 socket again this time next year maybe earlier. While it is truye that in the past Intel has played tag the @ss with socket changes, they have to their defence stuck to the same LGA 775 pinout for a long time now. Yes that doesn't help since most LGA motherboards on the market are not Core2 compatible, but still it does mean you can keep your current P4 and just get a Core2 comatible motherboard in the meantime that you can use with your current CPU.

Unfortunately socket changes for AMD seem rare but are not really, when they do happen they cost quiet a bit.
Moving from SlotA to Socket A was not fun at all. New Ram, CPU and Motherboard. Socket A stayed for ages, but when S754 came you only had to change mobo and CPU. Then again S754 was short lived and there came S939, needing once again a new CPU and motherboard.

Then shortly afterwards PCI-e changed the picture again needing a new Motherboard.
now again with AM2 and next year again with K8L you'll need a new motherboard and new CPU.

So when you think about it AMD has changed just as much as intel really.
There was no socket change between P4B and P4E 478, All 478.
In the same period AMD moved from S-A->754->939. Now to AM2 and next year another one for quad core support etc...
Kentsfield works just fine on current Core2 capable boards.

S754 didn't change to S939 - they had different markets. S754 is still going. PCI-e didn't require a change in CPU either, only in motherboard.

 

[ShockG]

No S754 is not going anywhere.
Last CPU S754 got was 3700+ C0 stepping CPU which was out 2003 already. Nothing faster ever came that way ever again, save for a few sad semprons. That to me means a socket change. That they over lapped is not really the point.

My bad about the PCI-e it was supposed to be new motherboard and not CPU... Fixed :/
