The Test Platforms

To see how much we’d be limited by Intel’s PCIe 1.0 slots and AMD’s new SB850, I put together a handful of test platforms.

I’ve got ASUS’ 890GX motherboard equipped with native 6Gbps SATA support. This board/chipset should give us full bandwidth to the Crucial RealSSD C300:


ASUS' M4A89GTD Pro/USB3

I’ve got Intel’s own X58 motherboard. With no on-board 6Gbps support I installed my RocketRAID 62X card into a PCIe 2.0 x16 slot, a PCIe 1.0 x4 slot and a PCIe 1.0 x1 slot.


Intel's DX58SO

Gigabyte sent its X58-UD3R motherboard, which has a Marvell 6Gbps controller branching off one the X58’s PCIe 2.0 lanes.

Next up is Intel’s P55 board where I use one of the x16 slots branching off the CPU socket, as well as a PCIe 1.0 x1 slot from the PCH. The results here should be equal to a H55/H57 platform, which I also verified.

Finally I’ve got ASUS’ P7H57D-V EVO with the PLX solution, just to see how well combining a bunch of PCIe 1.0 lanes to feed Marvell’s 6Gbps SATA controller works.

    Anand,

    I was going to maybe get two C300's for my current build. Do we consumers need to wait for your update before we invest in these?

    We know it died, but I haven't been able to find any other reliability statistics collated anywhere to make a buying decision on.

    Sorry, I missed the Update link in the upper corner.

    Great review. Not much to be said. There was a little bit of puffery at the end, in AMDs favor.

    I'm sure most companies have faster controllers/BIOSs to be released. Rather than saying AMD is something to look out for, for some reason I'd think Intel would have something greater.

    As you mentioned, the on-die controller should have lower latencies - could you ask them about this? Perhaps some of the PCI bandwidth is being chewed up by something else, or perhaps the latencies are too low, causing a check/repeat bottleneck? (or maybe this a marketing ploy to release something faster in the future)

    Because AMD has native 6Gbps and they are improving drivers. With intel chipsets you can't phisicly increase speed further.

    I don't like how Intel switches between [Mb/s & Gb/s] and [MB/s & GB/s]. It'd be nicer to not have to translate 480Mbps into 60MB.

    I guess the issue was at first past I almost equated the 480Mb/s to the 500MB/s right under it.

    You should not type dates in that format, and if you had an editor, he or she should absolutely stop you from doing such things. People have expectations. You might think it's no worse than the ever-present traditional ambiguous formats of the US and Europe (m/d/yy(yy), d/m/yy(yy)) which are bad enough, but at least it's an old and well recognized problem that people are used to living with, so long as it uses slashes. People with knowledge of standards, though, use dashes for ISO date format, yyyy-mm-dd which is also perfectly sortable. By mixing and matching styles haphazardly, you're only propagating the notion that anything goes, causing people to stop and wonder for 12 days out of every month. If you're deliberately adopting the style commonly used in the Netherlands (I had to look it up) and advocating its use for an international audience, I cannot imagine why.

    I know it seems crazy to harp on this and I kind of agree . . . but I am just so surprised to see it here, written by a detail oriented technically minded accomplished writer.

    If this is in response to the IOMeter build, that might be the way it was named by its creator, not Anand. Also, I would imagine 6-22-2008 is m-dd-yyyy

    Hey Anand, Why isn't the X-58 gigabyte native 6gbs board on the write benchmarks?
  • assassin37 - Thursday, March 25, 2010 - link

    never mind I read why, legacy mode
