Title: Dual core or 1MB L2 cache?
Post by: Ceathreamhnan on July 29, 2006, 01:17:42 AM
Which is better: a dual core X2 A64 with 512 L2 cache (two lots of obviously) or a same-power-rated single core A64 with 1MB L2 cache (San Diego core)? And in what software?

why not have a A64 X2  with 2x 1mb L2?

pretty sure thats what mine has

its a 4400+

dual core with half the cache would be marginally faster as itd be like dual channel ram able to do 2 things at once

How about a Ã,£70 odd 805D o/cd to 3.8 GHz?

Faster + Cheaper? Just a suggestion...

More than the budget/cpu potential depreciation ratio ;)

What are the heat issues like? Rather not run an oclocked setup as its for a colleagues kids gaming machine and I dont want lots of support problems. Im happy with the idea of a S939 A64 at stock.

They are on a 65nm process and run cool, even when o/cd AFAIK.

Well the target mobo was the Asus Crossfire chipset S939 board at about Ã,£60, what would the suggested Pentium home for the 805D be?

I recently set one up for a friend on a budget board - an Asus P5LD2 - of course, the P5WD2 is much better feature wise, but I was able to get him a steady 3.8GHz on air with the P5LD2 on stock voltage.

Faster, not.....

If you want faster you want a Core Duo 2.

That CPU BX is talking about is a sh*tty P4 based core, you want either a A64 or better still an Intel Core Duo 2.

the 805 is a good budget option atm

http://www.ebuyer.com/customer/products/index.html?action=c2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=101699

would go together well imo.

Wouldnt go for the 805 purely because you _need_ to overclock it to get the performance.

the X2s are cheap enough now that i would be looking straight at them.  Hell the 2800+ im still running cost me that much (Ã,£130), and it still does everything i want it to.

If you want faster you want a Core Duo 2.

Based on my experiences with my 4800+ x2 and superpi results, my 805D (o/cd) is faster at superpi (to 1M) than my 4800+ x2

Id go for a Core 2 Duo also

Well, interesting choice available - Ã,£120 or...Ã,£775! One presumes they havent quite got the pigs to market yet  :?

Ã,£775 for a Core 2 Duo Extreme Edition, yes. Get an E6300 and youre looking at a somewhat more reasonable price, Ã,£115 at Overchargers at the mo.

IIRC Toms Hardware has somethign up about the E6300 beating the X2 3800, however i trust them not a bit.  Anyone else remeber the A64/Intel face off they did, that had 13 hours where the P4 crashed they didnt mention?

Im waiting until just after christmas before I upgrade.  Well have some preliminary benchmarks from the next Gen AMDs and ill work out my options then.  This has happened before where Intel pulled ahead for a few months, to be absolutely left standing by AMDs next offering (athlon to AthlonXP anyone?).  

basically ill have ~Ã,£800 to spend on a box, at that type of money im thinking its worth waiting.  Dont accuse me of fanboyism, im using my P4 lappy at the moment, with the AMD say upstairs and the Celeron sat next to that.

Of course, Super Pi is the be all and end all of performance  testing:roll:

You can look else where and still see that the bottom Core Duo 2 is one hell of a performer.  Much cooler than the P4 offerings and even A64s.  Also OC much better too :)  On XtremeSystems one guy has already got 5.5GHz out of one, it did Super Pi 1m in 9 seconds! YES, 9 seconds.  3.5GHz+ is not uncommon with aircooling.

Seriously, pipe up the cash for a low end Core Duo 2, much better deal IMO.

Look at this list of reviews here - http://www.xtremesystems.org/forums/showthread.php?t=104147

To Summarise, a Core Duo 2 E6300(1.86GHz) is nearly always around the same performance as an A64 4600+(2.4GHz) and faster than all the Pentium Ds.

Yeah I was being a bit lazy, the Conroe stuff looks very good. At the moment though, there only appears to be expensive motherboards supporting it, so Id be better waiting a few months to get more options. Bear in mind that the Asus board I had in mind is only Ã,£60, and an AMD X2 would "be good enough" for most any game sw out there.
The guy who wants it needs to move his sons pc into his office and give him a gamer box instead, so I may not have that luxury of waiting :lol:

No, it just proves that it performs faster at superpi than my 4800+ ?

Id love to repeat that experiment the guy did with the 7GHz D805 - dont think the cooling would be too practical though! I have access to the liquid nitrogen in my girlfriends lab however....

Id be very suprised if the 7GHz P4 core could come anywhere close to the core duo at 5.5GHz tbh.

The core duo simply blows everything else on the market out of the water right now.

No need to be surprised or not, a core duo 2 at 5.5GHz is far far faster than a 7GHz P4.

Having used some Core Duo powered things @ work I can also say, that I think they are totally brilliant.

Intel, is indeed back with us making real CPUs

I ordered 4x 2.8 core duos and they (by a long, long way) outshone my work PC, which is a 3.2 P4 with Hyper-threading.

same amount of RAM in both.. 1GB
