Inflation and the ongoing chip crunch mean thatвЂ¦

RyanSmithAT: Intel has managed to set revenue records for 6 years in a row now.

Seems they've reserved their entire launch allocation for the shuffle

RyanSmithAT: Well it looks like Newegg is going to be a strike-out.

IanCutress: Let's make some CRAAAAAZY money!.

IanCutress: MI250X is just two GPU dies on the same package.

IanCutress: I'm referring to the global semiconductor workforce and associated adjacencies in this context, givenвЂ¦.

Since the disk speed is the bottleneck on my new computer, $750 is worth it just to prompt me to Crossfire my 5850 because the bottleneck shifted to graphics.especially with i7-920 OC to 4Ghz ) Intel just updated their ICH10R chipset firmware to pass TRIM to SSDs in RAID.hopefully Marvell does too. So far Gigabyte boards are the only ones with that controller it appears. It seems the newer Gigabyte boards UD4 or higher do have the newer controller and are better for RAID SSD expecially now that it is hardware supported.the open question no one has been able to answer is if the Marvell 88SE9128 will pass TRIM commands to a RAID SSD set. Unfortunately it does not support the RAID function but at almost 750 a drive I was not going to RAID for a while anyway.I AM happy I went with X58 for sure! I have been planning on the 256GB RealSSD for a couple of months now and am happy they started shipping.as one of the main reasons I had picked the Asus board was the native USB3 and SATA-III support. Whether it hurts performance though is harder to say since I can't test it yet ). Unfortunately on my Asus P6X58D, the controller is the older 9123 so the only way I could RAID a SATA-III SSD (or even mechanical) drive is using 'Windows' Raid, not firmware on the controller.

georgekn3mp - Thursday, Malink About the two different Marvell controllers 88SE9123 and the 88SE9128.the older 9123 does NOT support RAID and the newer 9128 DOES natively support RAID 0, 1 and 5.

Pair it with a PCIe 1.0 x1 interface and youвЂ™re down to 250MB/s (and much less in reality due to bus overhead). The 6Gbps SATA spec allows for up to 750MB/s of bandwidth, but the PCIe 2.0 x1 interface limits read/write speed to 500MB/s. The interface is only a single PCIe 2.0 lane. MarvellвЂ™s 88SE91xx PCIe 2.0 controller is the only way to enable 6Gbps SATA on motherboards (other than 890GX boards) or add-in cards today. ItвЂ™s not a problem today but eventually, with a fast enough USB 3 device, youвЂ™d run into a bottleneck. However if you connect the controller to a PCIe 1.0 interface, you only get half that (and even less in practice). Connected to a PCIe 2.0 interface, you get 500MB/s up and down, more than enough bandwidth for the controller.

The USB 3 spec calls for transfer rates of up to 500MB/s. The ВµPD720200 has a PCIe 2.0 x1 interface and supports two USB 3.0 ports. NECвЂ™s ВµPD720200 is exclusively used by all motherboard manufacturers for enabling USB 3.0 support. These 3rd party controllers are all PCIe devices, just placed on the motherboard. On Intel chipsets, you need a separate controller for both 6Gbps SATA and USB 3. AMDвЂ™s 8-series brings native 6Gbps SATA support, but USB 3 still requires an external controller. No desktop chipset natively supports both 6Gbps SATA and USB 3.0.

AMDвЂ™s 7 and 8 series chipsets donвЂ™t have any PCIe 1.0 slots.ДЄMD's 890GX doesn't have any PCIe 1.0 lanes

IntelвЂ™s X58 chipset for example has 36 PCIe 2.0 lanes off of the X58 IOH, plus an additional 6 PCIe 1.0 lanes off the ICH. This is a problem because all Intel chipsets have a combination of PCIe 1.0 and 2.0 slots. The only PCIe 2.0 lanes come from the IOH. Both can easily saturate a PCIe 1.0 x1 connection. Today, both USB 3.0 and 6Gbps SATA aim to change that. Thus the distinction between PCIe 1.0 and 2.0 has never really mattered. Other than graphics, there havenвЂ™t been any high bandwidth consumers on the PCIe bus in desktops. Instead of 250MB/s in each direction per lane, you get 500MB/s. PCI Express 2.0 doubles the bidirectional bandwidth per lane. One of our first encounters with PCI Express was at IDF in 2002 While that is the total aggregate bandwidth available to a single slot, you can only reach that bandwidth figure if youвЂ™re reading and writing at the same time.

Bandwidth in a single direction for a single PCIe 1.0 lane (x1) is 250MB/s, but because you can send and receive 250MB/s at the same time Intel likes to state the bandwidth available to a PCIe 1.0 x1 slot as 500MB/s. Each lane has an independent set of transmit and receive pins, and data can be sent in both directions simultaneously.
