Guest adrian_dav Posted May 24, 2002 Share Posted May 24, 2002 hi, i'm interested to see what kind of hardware configuration is optimal for radiosity processing in viz4. i created a simple scene. it is available here. could you download it, run the radiosity solution up to 96% and post the time it took as well as the specs of the hardware you used? please read the time used for the solution from the statistics roll-out in the radiosity panel. thanks! my trusty old dual-pentium3-boxes came up with the following results. computer A: CPU: 1000MHz Pentium III number of CPUs: 2 RAM: 1024MB motherboard: MSI 694D time: 13minutes, 28seconds ----------------------------- computer B: CPU: 800MHz Pentium III number of CPUs: 2 RAM: 1024MB motherboard: MSI 694D time: 17minutes, 15seconds [ May 24, 2002, 11:42 AM: Message edited by: adrian_dav ] Link to comment Share on other sites More sharing options...

Greg Hess Posted May 24, 2002 Share Posted May 24, 2002 Pentium 1.8A Northwood WinBlows 98 SE Viz 4 Asus P4B266-C 512 megs of PC3000 Mushkin DDR. Memory settings to 2-2-2 and 4 way interleaving Geforce 4 Ti 4400 (Software heidi used) 17 Minutes 59 Seconds I'm not entirely sure if I did this correctly, so I'll be running it again. I think I just rendered in which case its the radiosity + the render itself. So now I'm just using the radiosity panel to compute the time.

Guest adrian_dav Posted May 24, 2002 Share Posted May 24, 2002 17 Minutes 59 Seconds very very impressive speed. the rendering should have added something like 20 seconds. it seems that radiosity just scales well with the MHz and doesn't use the FPU-heavy features that are very strong on the athlon. you might be rightin the other thread and i'm fine with just 2 xeons. thanks for running the solution.

Greg Hess Posted May 24, 2002 Share Posted May 24, 2002 Note that the 1800+ XP (a 1.53 Gigahertz Athlon) Beats the 1.8A Northwood in this particular test. Even with the Pentium IV's almost 300 megahertz speed advantage, I think the powerful FPU of the Athlon is still dominating, making it the superior choice over the Pentium IV based systems. I'm curious to see if anyone has a Dual Tualatin system to benchmark. Link to comment Share on other sites More sharing options...

samp Posted May 25, 2002 Share Posted May 25, 2002 These results alre realy shocking me! I'm going to buy myself a new PC this summer, and I allways thought that for stuff like VIZ4 I deffinately needed to go for the Intel Pentium IV ! But it seems that AMD is the better choice. And with AMD I can maybe afford a dual CPU system Link to comment Share on other sites More sharing options...

And with AMD I can maybe afford a dual CPU system intel seems to be close behind amd when it comes to calculating radiosity at the same clock speed. nobody posted results for a p4 xeon 2.4GHz yet, but i assume it runs circles around the athlon MP 1670MHz(or 2000+ PR rating). that would be a relief for me. i use a dual athlon system right now. it runs very hot and needs a lot of cooling resulting in nasty noice levels. no more amd chipset on my mobo please! i'd like working USB, shutdown windows despite the existence of a firewire card, less heat and more predictable RAM support. it might have been just my tyan MP board, but it felt like an unfinished product from the beginning.

Greg Hess Posted May 25, 2002 Share Posted May 25, 2002 If someone posts the 2.4 Xeon. I'll post a Dual 2100+ MP and make them weep. The higher intel goes, the faster amd catches up . And yes I'm biased. My 1.8A northwood is slow as !@$(*7 compared to my AMD system. Link to comment Share on other sites More sharing options...
squid Posted May 25, 2002 Share Posted May 25, 2002 Be very careful if you're going to build your own AMD system though. I would recommend Monarch Computer,.Game PC, etc. Not Xi though. Link to comment Share on other sites More sharing options...

My 1.8A northwood is slow as !@$(*7 compared to my AMD system.the little chip war is the best thing that ever happened to us. i'm biased in both directions. i like AMD's raw FPU power and i like intel for being able to build a box that doesn't sound like a vacuum cleaner. since i spent looooong hours near my machine the noise is a bit of an issue. at least i don't hear the airconditioner as much . do things get better with the new athlons?

Greg Hess Posted May 25, 2002 Share Posted May 25, 2002 Noise is a problem regardless of which chip you go with. To solve either problem you need to do some research, and setup the cooling yourself. If your willing to do that, you can build dual systems with well under 35 db output. (Thats with 8 fans). Currently my default 1.8A Northwood is AS LOUD as my dual 1900+ MP system. So don't think that buying intel you automatically solve the noise problem . YOU have to solve the noise problem, AMD and Intel don't care . I commented alot on this issue in one of the other dual athlon threads on this forum about jeff's system. The easiest solution is replacing all the fan's in the case. Throw in some adjustable rpm fans, and you can tweak the noise levels and get the same quiet ambient hum throughout. This of course requires massive heatsinks on the cpu's, as you need to cool more with surface air then airflow. If noise is still a problem, there are a variety of insulators you can purchase to cut off front and top and side noise. I would recommend if you do this, to greatly increase the ventilation out of the rear of the case, to help hot air escape. Insulation also creates heatbuildup and nullifies all the advantages (cooling wise) of an alumnium case. The most advanced and technically challenging setup would be a water cooling system, contained within an insulated box, with an external resevoir and monitoring system to completely remove any and all fan sounds from the case area. The new AMD systems now include a downclocking system to reduce core temperature, just like intel has with the p4's. With the burning up problem solved, I really don't seen any reason going with an intel solution, unless your forced too, or have a specific program that utilizes SSE2. Probably the quietest system you could build WITHOUT rpm adjustable fans would be... A case using an enermax whispher powersupply, with 4 x pablst 16 CFM fans (18 db), with two silverrado's (around 60 USD each) as cpu coolers. That would then make the loudest part of the computer the rom and hd's. Link to comment Share on other sites More sharing options...

Dave Buchhofer Posted August 1, 2002 Share Posted August 1, 2002 Finally got the new box's in! the word is 9:23 radiosity Dual athlon 2100's. out of the box haven't tried to tweak them yet. unfortunately 1 of the 3 has this little thing where if you install VIZ, it wont boot! such an annoying thing.
