P55 or X58
Posted 02/01/10 at 12:33:38 PM by The Maximum PC Staff
I’m planning my next build, and I’m having a hard time deciding between a motherboard with the X58 chipset or one with P55. Is triple-channel RAM worth paying extra for? I plan to keep this PC for three years (until the motherboard warranty expires) and I’m worried that in three years there’ll be 9x-channel RAM or something crazy like that. I’m a heavy gamer but I don’t do anything else that requires a ton of memory—I don’t use AutoDesk or Maya.
Damien, although the memory bandwidth on X58 contributes to some performance advantages over a P55, the Doctor doesn’t think that that in itself warrants the extra coinage. What may be of more value to you, however, is X58’s ability to run dual x16 PCI-Express at full x16 PCI-E 2.0 data rates. The P55 platform inherently limits dual x16 physical slots to running at x8 PCI-E 2.0 speeds. Keep in mind, that’s still plenty of bandwidth, but the X58 will likely have some advantage at ultra-high-resolutions in games that need the bandwidth in multi-GPU scenarios. X58’s other ace in the hole is its ability to support the upcoming six-core Core i9 CPUs due early next year. P55 isn’t supposed to support those procs. Those processors, however, are likely to be very expensive, so if you don’t plan on spending $900 for a CPU, then you don’t have to worry about that, either.

USB3 and SATA-II Support

It also appears that X58 has better support for USB 3.0 and SATA-III drives, as it is not limited to "stealing" bandwidth from existing PciE lanes. The P55 only has 16 "native lanes, so adding USB3/SATA-III to that chipset reduces the video bandwidth unless you add a bridge chip like NForce 200 to the board. And even then on some new boards you can lose that speed boost if you add an extra video card.
On X58, which has more channels, when you add USB3 and SATA-III you do not lose any native speed for multiple video cards.
On my Asus P6X58D, I can run 2 video cards at 16x/16x natively and still have USB 3.0 and SATA-III both at the standard 6GB/s. Very few P55 boards can do that, and certainly not as "true" 16x/16x.
Definitely an advantage in the future.

good point Damien

good point.....i like the x58 for this reason.....plus i plan to keep my mobo for several years,so that 900 dollar 6-core cpu,will be around 200 1 or 2 years after it comes out.
good point george....i did'nt know that.
