Sapphire PURE Innovation - ATI's Chipset for the AMD Enthusiast

Disk Controller Performance
With so many chipsets and brands of storage controllers on current Athlon 64 boards, we needed a means of comparing performance of the wide variety of controllers. The logical choice was Anand's storage benchmark first described in Q2 2004 Desktop Hard Drive Comparison: WD Raptor vs the World. To refresh your memory, the iPeak test was designed to measure "pure" hard disk performance, and in this case, we kept the hard drive as consistent as possible while varying the hard drive controller. The idea is to measure the performance of a hard drive controller with a consistent hard drive. We played back Anand's raw files that recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's IPEAK utility was then used to play back the trace of all the IO operations that take place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance difference to the controllers that we were testing, we used Seagate 7200.7 model SATA and IDE hard drives for all tests.iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each IO operation. In order to make the data more understandable, we report the scores as an average number of IO operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned as it is just the number of IO operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.
The Sapphire PURE Innovation is a really excellent performer in iPeak tests. The new SB450 turned in some of the highest iPeak measurements that we have yet seen in IDE and on-board SATA. While the SATA controller of the SB450 is not the SATA 2 used by the NVIDIA nForce4, its performance is even faster than nF4 when running our stock SATA drive.
In past benchmarking, IDE has provided the slowest IO performance in this roundup. However, ATI IDE breaks that trend, with IDE performance to be the best that we have measured since we have been testing with iPeak.
Sapphire and ATI have also done an excellent job in implementing the Silicon Image 3132 chipset for SATA 2 performance. The 3132 was blazing fast in our benchmarks, setting new iPeak performance records. For disk storage - IDE, SATA, or SATA 2 (with the Sil3132) - the Sapphire ATI delivers outstanding storage performance.

only thing that i would like to know is the pricing, since its on par performance wise with the other entusiast boards, the one thing that will seperate itself will be pricing.L3p3rM355i4h - Friday, July 29, 2005 - link
WTF, these aren't bartons! Props to ATi for including something that high. 4.0vdimm is good too.The white PCB is....interesting, to say the least. Just going to leave it at that. ;)
If these are actually out in Mid-October/Nov. I'm def. going to get one.

I am impressed to say the least. IGP versions will be coming along with Crossfire versions. There are 4 different flavours coming and 8 if you count the addition of IGP. This may lead to a breakthrough into the OEM's. The true test will be how the intel chipset performs.Excellent job ATI!

That white mobo is supa hot. When I saw that pic, my jaw dropped. PRETTY MOBO.Too bad I'm an all-Mac shop now. I need a mobo like this in my G4. :-P

I wanted to buy this mobo when I saw the awesome colours, but the featureset sealed the deal. If this board can overclock like it should, I will buy it without any further question. This has massive potential..fitten - Friday, July 29, 2005 - link
Just think.... now if they just had a TypeR sticker on it somewhere... :rolleyes:xsilver - Friday, July 29, 2005 - link
is there any mention of the price? Competitive performance at a non competitive price still means little for ATIand also the limited availability (ala rs480) might also kill some of this products hopes
hopefully though they will make a spash and give nvidia a kick in the pants to lower their prices :)

Nice to finally see a amd64 board with decent quality onboard audio, wonder if anyone will revise their nf4 boards to support the better codcec?Zebo - Friday, July 29, 2005 - link
I guess you missed the MSI with on-board SBlive?
