Intel P35: Intel's Mainstream Chipset Grows Up

Audio Encoding Performance
Our audio test suite normally consists of Exact Audio Copy v095.b4 and LAME 3.98a3. We did run these tests with basically the same results but for our purposes today we will utilize iTunes 7.1 as it is one of the most utilized audio applications available due to the immense popularity of the iPod. As in previous articles, we are using an INXS Greatest Hits CD for testing, which contains 16 tracks totaling 606MB of songs.Our first test consists of utilizing iTunes to rip our INXS CD in WAV format onto our hard drive. Even though CPU speed and optical drive selection have a great impact on these test results we are using the same optical drive between platforms for each test.
It's interesting to see our two boards from ASUS and Gigabyte at the top showing a clear separation from the rest of the pack. It wouldn't be surprising if the results of the two top boards are a result of a BIOS tweak not present on the other boards (yet). Excellent memory bandwidth and latencies are a plus for encoding although, even though these tests remain CPU and at times storage system sensitive.
Our next two tests have us utilizing iTunes to convert our WAV files into ACC or MP3 compatible formats. We utilize the 320kbps setting for both tests with the MP3 test also utilizing the variable bit rate option.
We see iTunes favoring boards with excellent CPU throughput with the 1333FSB showing a slight advantage in this test. All of the P35 boards place ahead of the older chipsets, with the exception of the MSI board. As we have mentioned already, the MSI board appears to be about two BIOS updates behind the Gigabyte and ASUS offerings right now, so we expect its scores to improve to match the other offerings with a few more updates.
Our final test has us creating a legal use copy CD from the base WAV files we collected when ripping the INXS Greatest Hits CD. Not that the world needs any more of these CDs but it makes for a good closing test. We promise all CDs are destroyed after testing much to the pleasure of our ears and those at the RIAA.
Once again our test results are extremely close with the optical drive playing a leading role in ensuring our results are fairly close. The minor differences are all attributable to the better disk performance of the P35/ICH9R combination in this case. We noticed in this test that the ICH8, ICH7, and 680i LT equipped boards always started writing to the DVD drive a little slower on the first track than the P35 boards.

X38 is basically ready, going through some fine tuning now... I understand it will be held until after the 1333CPUs are launched and DDR3 availability is a little more widespread/cost effective. I expect late August right now, but you never know with Intel. ;-)JarredWalton - Monday, May 21, 2007 - link
Technically Q3 is any time between July 1 and September 30, but if they're saying Q3 right now it probably means some time in August at best.gigahertz20 - Monday, May 21, 2007 - link
I applaud ASUS for only including 1 legacy connection on their P5K series, and not 4 like Gigabyte has chosen to do for their P35 board. Death to legacy connections!I mean really, why even include those damn legacy ports. The enthusiast that buys one of these boards will not be using them, they are a waste of space. Instead of having them, they should replace them with more USB ports or something useful.

I still have a parallel based laser printer that works fine for what I need, and I'm quite happy using it until it dies. There are also people that use serial devices that cost a lot of money. I don't think every board needs legacy support, but it's good that there are still options for people that *need* certain legacy devices. I've got several KVM switches that won't be useful if PS/2 ports disappear. :(yacoub - Monday, May 21, 2007 - link
Don't they offer USB or eSATA to serial/parallel convertors for those sort of situations? :)JarredWalton - Monday, May 21, 2007 - link
Sure, but I haven't had the need to try one yet. :)Truth be told, my printer has a USB port, but it behaves very poorly using a USB connection. It's a Brother HL-1240, and if the printer isn't powered on when you boot, Windows won't see it unless you unplug it and plug it back into a different USB port. It just works better with LPT, and as I said for my needs it's sufficient. The way I figure it, having the ports there isn't hurting most people. I've never seen anything to indicate they hamper performance, and how many extra transistors are "wasted" on these ports? Maybe a few thousand? Heheh. 45M transistors on the P35 is a bit crazy....
For what it's worth, between mouse, keyboard, and my LCD (which actually has four USB ports and flash memory readers), I haven't had any need for more than four USB ports on a motherboard. But then, I've got too many PCs around anyway.

I agree with you, but for another reason.I don't like USB at all, because a few years ago I ran some tests, on motherboards ranging from MVP3 based to a KT880, and USB seems to have a negative impact on performance, particularly on memory, in many cases.
It doesn't make my keyboard work any better, or my mouse, and I'm not sure why I need it for those functions at all. PS/2 ports don't do it well enough? I'm not crazy about this one size fits all approach, especially when it comes with overhead. The current ports work fine.
USB is a crappy, bloated technology. I'm not sure the "S" should stand for "serial" at all, I think there is a better word that begins with S for it.

Wake me up when Bluetooth works over PS/2.Though one reason to still include PS/2 keyboard/mouse is that it is hard to screw up support for those in Linux kernels. Same can't be said about USB.
TA152H - Tuesday, May 22, 2007 - link
Wake me up when I need Bluetooth.You could implement Bluetooth easily if USB didn't exist, but you're missing the point anyway. When you have to use USB for stuff that is handled more efficiently by PS/2 ports, it's a bad thing. Or other ports. It adds no function for these devices, and comes with overhead. It's a bad idea, but of course Intel was in the mode of making as many things as possible use CPU power so they could keep selling their latest and greatest.
It's just a rehash of some dorky Apple stuff that most people here don't remember. The original MacIntoy didn't have any slots, and you'd attach stuff to some serial bus for expansion. Naturally, it didn't work out, and they had to add slots. At least they didn't get rid of slots for USB, they just made it bloated.

Man, if the P35 boards are going to be around the $250 mark, I'm not looking forward to see the price on the X38 boards.... :-(
