Hi, Iīm from Brazil and Iīd like some help and advices.
Iīm considering buying a 64 bit computer system.
I woulīd like to take advantage of the 64 bits microsoft OS and 64b Lightwave.
What system do you recomend? (motherboard and cpu)
Intel or AMD?
I actually use a Asus P4c800 deluxe motherboard and a P4 3.2 HT system, lets say I decide to buy a similar system but 64 bits based, how faster would be a lw render, for example?
Is there any site with some comparative informations about the difference?

Thanks a lot, and sorry if I didnīt make my point in the question, but my english sucks.

64bit basically allows you to take advantage of more RAM (32GB) as opposed to the current 32bit limit of 3GB (2GB with windows). In terms of render time, not sure if you'd see *that* much improvement.

If you want to see the biggest improvement, you'd be better off getting a dual core system.

Bear in mind tho, that if you get a 64bit system, you'd have to get drivers for all the hardware, and make sure that you fully update your BIOS to fully take advantage of it.

I bought the MSI motherboard with AMD CPU. Haven't tried LW on it yet, waiting for the 64bit version. I missed out on the beta. Bought an ATI compatible card, with no problem from the 64bit catalyst drivers. I heard of issues with the Sentinel drivers but I won't know that until I get LW64. It should have render improvements since LW seems to use 128 bit. With 64 bit it would take two cycles instead of 4. It would have to decrease any CPU cycles that use greater than 32 bits.

Ok, iīm going to look for a motherboard that supports pentium D cpu, one that suits my pocket and most of all one that I can buy here in Brazil. I started looking for a Intel 8 series pentium processor but its being really hard to find a reseller here.

By the way, thanks a lot for the help.

Whereisanykey, please post your results when you get lw64, Ok?

tks again.

I second the "dual core" as the way to go. Memory is important
but for speed processing power is the key. Now the question is
who sells a good dual core system? Is the Intel Dual core any
good? I saw some cool 64 bit systems on Dell's website.

Anybody know how to compare the CPU speed increase of a dual
core over say a 3.0 GHz Pentium? Are talking about doubling
processing speed over a 3 gig?

Tom

Theoretically, if you have a dual 3.0ghz core compared to a 3ghz core, the speed should be double. However, this depends heavily on the application. Some applications that support dual CPUs will run close to twice as fast. On the average however, expect around 1.5x to 1.75x performance. So, if something used to take 100 seconds to render, it should now only take 57-66 seconds.

I've got an AMD 64bit cpu with GAk8nf9 Mainboard with a 6600 PCIE vga card and 1 Gig dual channel RAM. I'm waiting for lw64 to see how much the performance will get better. It was faster than my AMD Athlon xp :)

An ASUS A8N-SLi m/b and a AMD 4400+ dual core here...very impressed with it in lw.

once again, thanks for the replies.
As I said before iīm still looking for a Intel dual core system to buy, itīs hard to find some reseller here.

I'd suggest you hang on for a bit. Dual is the way things are going and may end up kicking yourself wishing you had gone dual64 Cpus when dual core becomes mainstream fair. Unless you have the $$ to play;)

You should get the best of BOTH worlds. Dual core 64bit.

AMD releases "budget" dual-core CPU, drops prices (http://arstechnica.com/news.ars/post/20050801-5155.html)

8/1/2005 10:27:12 AM, by Eric Bangeman (eric@arstechnica.com)

AMD's recent dual-core Athlon releases (http://arstechnica.com/news.ars/post/20050531-4955.html) have been noteworthy as much for their high price as they have been for their performance. While the Athlon 64 X2 4800+ took (http://arstechnica.com/news.ars/post/20050509-4884.html) Intel's best out behind the cafeteria, beat it up, and took its lunch money, it was also expensive, coming in at US$1,001 per CPU in quantities of 1,000 at its release. By way of contrast, the new budget Athlon 64 X2 3800+ (http://www.amd.com/us-en/Corporate/VirtualPressRoom/0,,51_104_543%7e100309,00.html) is a comparative bargain at US$354.
If the 3800+ moniker rings a bell, that's because AMD already has a single-core, 2.4GHz 64-bit processor with the 3800+ description (for about US$25 less). Architectually, the new X2 3800+ is most similar to the Athlon 64 X2 4200+. It shares the same 512KB L2 cache as the the 4200+, but is clocked at 2.0GHz instead of 2.2GHz. It also uses AMD's HyperTransport technology and sports DDR controllers for each core. The release of the 3800+ also marks the full transition of AMD's processor fabrication to the 90nm process.

At least the high end of AMD's product line is getting a bit cheaper, as the chip maker also announced some sweeping price cuts across the whole product line. The aforementioned 4800+ has dropped to US$902, while its fastest single-core CPU, the Athlon 64 4000+ dropped from US$480 to US$375. AMD has also reshuffled the Opteron lineup, dropping the 140 and 240, while dropping prices as well. Last of all, the company dropped the Mobile Athlon 64 CPU in favor of the Turion (http://arstechnica.com/news.ars/post/20050107-4510.html).

All in all, it's a nice price drop for AMD fans, and the release of the low-cost, dual-core 3800+ might prove attractive to consumers who are looking for dual-core performance but are scared off by the relatively high prices. Could the new offering find its way into this month's Ars System Guide (http://arstechnica.com/guides/buyer.ars)?

Now about that 64-bit and dual-core aware software...

good news!
take a look at the LW8 benchmarks (http://www.xbitlabs.com/articles/cpu/display/athlon64-x2_15.html) so far...they weren't testing with LW64 bit as far I can tell :bounce:

Iīm considering buying the following system

motherboard - asus p5wd2 (chipset 955x - liked its later cpus upgrade possibilities)
cpu - pentium D 820
ram - havenīt decided yet (accepting sugestions)

iīve found this a good system based on the following benchmark
http://www.xbitlabs.com/articles/cpu/display/pentiumd-820_15.html

Also found very impressive the Amd X2 benchmark posted, but that system kind of exceed my budget.

Someone has any sugestions or advices about the p5wd2 motherboard?

once again tks for your replies, and sorry about the bad english.

Intel CPU and Asus MB sounds like a good pairing and reviews on the MB are good, but keep in mind, you're jumping on the bleeding edge. check this (http://www.tomshardware.com/cpu/20050603/stresstest-08.html)

Tks for the THG article iīm now aware of some problems i may have but still think that the asus pw5d2 and the pentium D 830 system, is going to be my final choice.
The pw5ad2 motherboard seemed to be a smart choice in the upgrades question, specially cause of its chipset, i think the motherboard will be able to receive some good cpus upgrades during its "life". I intend to buy the pentium D 830 now and maybe when intel releases some pentium D with HT support, and of course a friendly price i can upgrade it.

Is there anyone with this system running LW8.3?


once again tks for the replies.
man, this forum really works, heheheheh
:buttrock:

PS.: I heard that intelīs pentium D arenīt really DUAL CORE, but MultiCore, with no total paralel processing. is it true?

Glad to help, but just to keep your idea of the forums intact...better stay away from the LW9 thread :shrug: :D
