I have to put in my doubts about it's effectiveness, and standardness of result. Because you are basing your results on a test of file compression, won't it speed up or slow down depending on hard disk speeds too? And I doubt that is what you are intending to test.. The amount of memory the person has also would probably come into play, as the computer with enough ram during your test wouldnt be using virtual space, while the computer with say 128mb would most likely use it, slowing it down (and that would have nothing to do with the cpu / memory speeds if thats what you are testing).

ok sounds good mechBgon.. I guess just make sure you are using the same version of winzip for all the tests.. because a newer version may have an improved or more efficient compression algorythm that would make it appear that things are lots faster when it's just the version of winzip.. but I'm sure you know that. What version of winzip are you using in all your tests?
That really surprised me about the Athlon XP 1.4 being faster than the P4 2.4Bghz........ what's up with that? It makes me think your test doesnt test all the aspects of the chip (a game must run faster on a 2.4 than 1.4) OR that Pentium 4's are much overrrated? What do you think?
True, winzip is a real world application test, but so are other tests, namely the # of frames per second in a game, and that is really what matters to me. So even if a 1.4 Athlon XP could *winzip* faster than a 2.4ghz p4, i would still take that 2.4 if it made my *games* faster....
so many tests.... so much confusion I may run your test when I get my granite bay motherboard. I plan to overclock to 166mhz bus speed, so that would theoretically give me 5.4gb/sec max transfer rate, which SHOULD be much more than a dual RDRAM system.

I'm not surprised that a DDR333 system is beaten by a PC1066 RDRAM system, as almost all rambus systems have been using dual channel, whereas all DDR motherboards up until the Granite Bay have been one channel. Here's a little info on the memory I found helpful:
DDR (one channel):
PC3200 (DDR400), 200MHz bus DDR, 3.2 GB/s max transfer rate
PC2700 (DDR333), 167MHz bus DDR, 2.7 GB/s max transfer rate
PC2100 (DDR266), 133MHz bus DDR, 2.1 GB/s max transfer rate
PC1600 (DDR200), 100MHz bus DDR, 1.6 GB/s max transfer rate
RDRAM (one channel):
PC1066, 533MHz bus DDR, 2.1 GB/s max transfer rate
PC800, 400MHz bus DDR, 1.6 GB/s max transfer rate
A system with PC1066 ram would be using it in dual mode (as almost all motherboards that use RDRAM use it in dual mode), therefore:
Dual PC1066 ram = (2.1gb/sec x 2 channels) = 4.1 gb/sec
A single channel Dual DDR333 solution:
Single DDR33 ram = (2.7gb/sec x 1 channel) = 2.7 gb/sec
So you were comparing 4.1gb/sec dual rdram to 2.7gb/sec single ddr, and thus of course the rdram is faster.
Now this takes us to why Granite Bay is so good. Because:
Dual DDR266 ram = (2.1gb/sec x 2 channels) = 4.1 gb/sec
which is equivalent to a dual PC1066 RDRAM solution, and if you overclock the bus on a GB board from 133mhz to 167mhz, you get the benefits of DDR333 memory, assuming your memory can handle that speed:
Dual DDR333 ram = (2.7gb/sec x 2 channels) = 5.4 gb/sec
Overclocked bus speeds on a Granite Bay system should OUTPERFORM a RDRAM solution, and *rougly* equal the speeds when not overclocked. Now you could overclock the RDRAM system too, but at least Granite Bay is the first to match it.
Hopefully that helps show it all.. Im not trying to be a know it all or have a big ego, so hopefully it didnt come across like that. Finally we have a solution that makes RDRAM outdated. Now, if only granite bay motherboards werent so darn expensive themselves If that's your concern then you can wait for Springdale or one of the other dual ddr solutions coming in the next few months, which should be both faster than Granite Bay, and less expensive.
from Evan's E7205 (Granite Bay) articleUsers looking at purchasing an all-in-one solution will love the P4G8X; Serial ATA RAID, Gigabit LAN, sound, FireWire, USB 2.0, and a dual channel chipset are excellent features for users that need as much as possible on a motherboard. VGA is just about the only thing missing from the P4G8X that all-in-one minded users might need. Though the price will initially be steep ($190), this is to be expected with a dual channel chipset, especially one from Intel. Prices will fall though, and we expect motherboards like the P4G8X to get as low as $140 in the next couple of months.
but at 32bit it is acting as the dual 16bit would, so in that respect the figures i gave above still hold. Now, what would be pretty interesting is if they made DUAL 32bit RDRAM....... where that would take us, would be quite nice (something like 8.4gb/sec?!? maybe that will happen when system busses can handle that much data without being saturated, but 4.2gb is the current limit with 533mhz bus systems.... and by the time 'dual 32bit rdram' could be used it would be probably outdated.... just lots of jumbled thoughts for u )Even this is still single-channel RDRAM.

Unless you plan on doing a LOT of winzipping (some kind of a professional winzipper *laugh*) then you probably will want to start looking at more sensible, and more of a variety of real life benchmarks. Perhaps there is some explanation for that "anomoly".. which i'd be quite interested to hear... It really does come down to how it performs, so no benchmark can take that "truth" away
Yeah as far as I can tell, the cost of Granite Bay is all that is holding it back for most users.
So hopefully GB will perform pretty darn close to 850e solutions, if not QUITE as good. (thats why im going overclock *evil laugh*)As for "sensible" real-life benchmarks, look at the results here and here.

As for that intel 860, that sounds cool... are there any motherbaords that use it yet? or is it one of those things that we'll see in many months from now. I'm not that up to date on that chipset.. obviously, this is the first *i've* heard of it.
happy new years... im off to celebrate
The 82850/82850E MCH and 82860 MCH both use a dual-channel design. They both have two 16-bit RDRAM channels. The 82850E MCH can use 32-bit RIMMs (that have two 16-bit channels on the same RIMM) or two 16-bit RIMMs (that have a single 16-bit channel on each RIMM) together, either way it's using two 16-bit channels in a dual-channel mode of operation. The i860 uses an MRH-R (Memory Repeater Hub) to split each RDRAM channel into two channels to double the maximum memory capacity - not the bandwidth. So, even though i860 has 4 memory channels they still operate off of two 16-bit RDRAM channels in the same way i850/850E does. So, effective bandwidth is the same (2 x 1.6GB/s = 3.2GB/s) even though memory capacity is doubled. The 82860 MCH does NOT use a quad 16-bit channel design, nor is it a dual 32-bit channel design either.Originally posted by: mechBgon
By "dual-channel" for the RDRAM, are you referring to the combination of the two 16-bit modules into a 32-bit data path? Because there IS a genuine dual-channel RDRAM chipset: Intel 860. i860 is real dual-channel RDRAM, and it only supports Xeons. Intel 850 and 850E are not dual-channel.
While searching on ebay stores, I stumble on a store that has the regular Asus P4G8X for sale for $211.97. I don't know how to make a link but here is the address:

Edit: Nevermind, I just got an email back from him. He doesn't have them in stock.
