What are the differences between the Venice Core (E3) 512KB L2 - And the San Diego Core (E4) 1MB L2 Besides the cache increase?

Thanks :)

and Dont know if this will be related in any way or not... But on Venice we still cant do 4x512 @ 1T... will we be able to on San Diego? How about Dual Core? Thanks ;)
 
nothing. just the cache, they are otherwise identical.

i know 2T isnt ideal for four double sided dimms, but its better than running DDR333, and with the improvments to the memory controller, 2T shouldnt be as bad as it once was (or so ive heard)
 
there are rumors of a different thermal shutdown method on E4.. though i don't see why they would do this, the rumors are there.

other than possibly that, and the cache size.. there isn't anything that i know of. also remember that some venice cores will actually be san diego with 1/2 of the cache disabled, just as some newcastles are really clawhammers ;)

Hah, and those half cached clawhammers were great, just like my C0 2800+ ;)

I'm sure you'll be able to force 1T mode and maybe loosen something here or there for it to work.
 
i dunno, right now, if you have 4 sticks and try to run 1t.. either the mhz has to be dropped a lot, or the computer will simply not boot at all
 
I'm still baffled at this 2 gigs of ram thing....but I guess that's just me. I ran fine at 512MB of DDR400 stock at 3-3-3-8 and added a second stick just to make sure I wasn't choking...and I notice a difference but I don't really need anymore, and I consider myself a power user between gaming and burning stuff/listening to music/etc. 2 gigs still seems overkill and I have yet to see an application where its good OTHER than in servers.

We (them nine thirty niners) shall see. If they are able to get it to 1T DDR500 then I might consider a venice, but until then, I see no reason to go with that over what I have now.

Supposedly WoW and EQ2 will eat any ram you can feed it.

i play wow. sure, there was a difference between 512mb and 1gb.. most of it was load time though. once the game starts up, it's fine :D

you have a bad-ass cpu
 
Eclipse was right, AMD changed the thermal shutdown procedures with the new San Diego (E4), or did something to the thermal management of the processor. That is the reason why there have been problems with San Diegos in current NF4/NF3 motherboards. This should however be fixed with a BIOS update.

speak for yourself, my full cached clawhammer is great.

And the dual core's will be called toledo, incase yww
 
he was joking about that 2800+.. notice the 3700+ in his sig? ;)

and to be more specific, the dual core opterons will be Egypt, Italy and Denmark (8xx, 2xx and 1xx, respectively)
then the a64-X2 will be Toledo, as you said.
then there will be a dual core Turion.. but i forget the codename. something strange
 
Grr.. If only I could *know* I was getting a decent overclocking Winchester right now, I would get one... but lately a lot of people have been having horrible OC's, so I'm doomed to wait for AMD to provide my salivating self with a Venice or San Diego, grR!

P.S. Eclipse what server are you on in WoW?
 
well actually it seems that the clocks are.. going back up. dunno why, maybe it's just me imagining things.

o/t: Lothar, i have two chars, an alliance night elf druid named Blark and a horde troll mage named Hehe :D
(don't ask how i managed to get hehe, but it's funny when i complete quests.. "good job hehe, i want you to do blah blah blah now"

For me its what I want. When I build systems, I go all out. I already have ran 1 GB of Ram in my Box for 2 years. 2 years ago it was concered overkill but look now, its optimal to run 1GB. I future proof my stuff as soon as I get it. my next box I again am going all out, I will get a dual Core hopefully Athlon 2.4Ghz, Vapochill it to 3Ghz, and I want 2 GB of DDR Ram @ 500Mhz cas 2-2-2-6 (OCZ VX) but I want it to run at 1T. If I cant, I might just go intel so I dont have these memory problems. I hope they can fix that issue, i really do.
I just want max performance. And sure 1GB of ram is more than enough now, however in 1 year from now, we are all going to concider it the High end, with 2GB being Supreme. I wont have to buy anything, for I will have already had it :)

you can have 2gb at 1T. you just need to get 1gb sticks.

if you really wanted, you could probably go for 4gb.. but that gives the risk of having to run at 2T... so 2x1gb is probably the best bet for the time being

True, however I deffinaly want OCZ VX memory. I deffinalty want 500Mhz Cas 2-2-2-6. That performance would deffinatly be killer.

How i have it figured out is this: Cooling with vapochill I think i can get 3Ghz Per core out of a dual core Athlon. 250FSB x 12 Multi - 250 HyperTransport x 4 (1000) so I dont lose any there. and 1:1 memory ratio. All around performance Increase. The system would fly. I just dont want 1GB of memory. Yes Its more than enough right now, but in the future It wont be, and I dont want to have to add memory later only to find i have to run at 2T and lose 10% performance.
 
well, that's a consequence you will have to face if you want to overclock 4 dimms. fortunatly for intel, switching to 2t doesn't effect performance quite as much, so they can have more memory without feeling the side effects.
 
Is their any chance at all of AMD revamping their memory controller again for the release of Dual Core?
 
definitly a chance... they changed it in clawhammer, going from the terrible C0 to CG, then later the CG clawhammers got a slight tweak, which newcastles seemed to have had from the start.
then there was winchester. usually good, but sometimes not. it seems that they have put for considerable effort to get venice to work at 200mhz with 4 double sided sticks... they could still have a few things to change though.

I would assume they would revamp it to work better with two seperate cores, unless of course the crossbar latch (is that the right name) will deal with that.
 
Sorry, what? Venice? San Diego? Why have i never heard of these as AMD cores?

Because they were just released monday.

Venice: successor to Winchester
San Diego: 90nm successor to Clawhammer

Wait, wait, I thought the San Diegos were scheduled to release around April 14 or 15? If both were released on Monday... linkage?

I dont have any links, but both have been in production since last year. They are not available in stores yet, really. And you're right, the San Diego is supposed to be released later than the Venice.

The dual core turion is codenamed 'Taylor.'
The regular mobile 64 dual core is Trinidad.
Both rumored to support DDR2, not sure on pacifica, presidio, or even socket.

Pacifica and Presidio will be on M2. DDR2 seems to be an M2 thing, though S1 just doesnt have very many details. My theory is that S1 will replace S940.
 
Well, in that case, what's the advantage of having a San Diego instead of a Venice? Does the cache really improve performance by a noticeable amount?

I find that it improves many of my games by about 5-15 FPS with equal clocks. I'm comparing my 3700 at 1.8ghz to my 2800+ at 1.8.

Probably about 5%, if its anything like the clawhammer/newcastle 754 cache difference.
