3800+x2 vs 4200+x2

When they're not the same then ?!?! ;)


no 2 chips overclock equally :)


not that it really matter all that much, the amd k8+ have never been really cache dependent

theyre the same physically. they set the cpu multiplier and lock it.
no two chips overclock equally... but you have the same chance of overclocking an x2 3800+ as you do a 4200+.... the only thing a 4200+ guarantee's by buying it is 2.2ghz rather than 2.0ghz... not necessarily 200mhz more after overclocked.
for instance, an X2 3800+ was overclocked to 3.0ghz in overclock.net...
just as an FX-55 was overclocked to 3.7ghz :)

its the individual chip... spending more money for a 4200+ doesnt mean diddly except for the different multiplier and the model #
 
Why a X2 4200+ is better than a X2 3800+ is that they are tested to see what they can run at, then are downclocked. Yes, they are the same (basically), but the X2 4200+ is better because it was selected to be a X2 4200+. The reason that everyone else doesn't just buy a X2 3800+ is that a X2 4800+ will overclock more because it is the ones that are selected because they run faster. No, a X2 4800+ may not overclock the same amount of ghz more, but it still is faster.

funny, you see my processor benched higher than a 4800+ and they didn't post back? lol :P
i plan on getting to 2.7-2.8ghz with some water cooling once i get the money :) (correction i have the money, getting my father to let me is another thing)

actually, mine is better than the 4800+. cache doesnt matter as much as frequency. also, id like to see where this 4200+ at 2.74ghz is??? lol NOT gonna happen!
as i said, same chip, different multiplier. if you know how to overclock (that is, the cpu while keeping the rest of the system stable by using lower hypertransport multipliers + memory dividers) then you can easily get the X2 3800+ at the same overclock as the 4200+

note: my processor beats the 4800+ :P

if your X2 3800+ can be overclocked to 2.2 GHZ, the X2 4200+ can be overclocked to 2.4GHz, if your X2 3800+ can be overclocked to 2.4GHz, X2 4200+ can be overclocked to 2.6GHz, IF your X2 3800+ can really be overclocked to 2.6GHz, then X2 4200+ can be overclocked to 2.8GHz

and if you get water cooling and your X2 3800+ really did get up to 2.8GHz, then if that was possible, if you were using a X2 4200+ you could get up to 3GHz...

of course i doubt your going to get ur 3200+ up to 2.8GHz and keep it stable... and i doubt an X2 4200+ could get up to 3GHz and be kept stable... using a $200 water system i doubt u could...

What absurd logic.

http://www.xtremesystems.org/forums/showthread.php?t=59753

Check the WR for X2 3800+ and X2 4200+, and you'll see that the clock speed margin between the X2 3800+ WR and the X2 4200+ is 50.17MHz, in favor of the X2 3800+.
 
I don't really agree with Clutch or Encore4more. Some random guy could be using phase change on his X2 3800+ while the X2 4200+ was just using watercooling or something. Or the guy with the X2 3800+ probably just got a lucky chip.
However, encore4more's logic isn't correct either.

They are almost identical, but the 4200+ is at 2.2ghz while the 3800+ is at 2.0ghz.

id much prefer the 3800+ just because its cheaper.
of course, if you dont plan on overclocking then get the 4200+
if you do plan on overclocking, then get an opteron 165. more cache more overclockability :)

havent we covered this. Cache is not that important for amd, and oppys are more expensive than there standard amd64 (x2 or not) counterparts. Sure you get about 10% more OC room (if you lucky) but you also pay about 10% more in price.

We are talking about world records, so it's quite obvious that they would both be using extreme cooling solutions.
 
I personally bought the 3800 to save money from the 4200. I have it overclocked to 2.5ghz which beats the 4800 and I saved 500 dollars on that part the only thing i dont have is the l2 cache but I never use all that. So If you have a budget I would buy the 3800 and just overclock to meet the 4200 or you can go up from there. I got the 3800 running at 2.5 and 42 degree celsius at full load and fan not at full load, using regular paste on the processor so I could easily get it to go below the 40 mark!:P
 
Im just a gamer I dont do to much multi-tasking at the moment! My computer has 2 x 512KB L2 Cache and 3gb ram I dont think I need more. However Im not a 100% computer person so I dont know!
