Sandy Bridge-E is now scheduled to release X79 in November
The high-end fever platform is always exciting, but the progress of Intel LGA2011 Waimea Bay is not very smooth, especially when the storage problems are difficult to solve for a time, resulting in delays in the release time and the functional features will be forced to streamline. The Sandy Bridge-E Core i7-3000 series processor and X79 chipset were originally scheduled for release in the third quarter of this year, but were postponed until the fourth quarter, and even once there was news that it would wait until 2012. There have been road maps showing that they will be released in October, but the latest date has been changed to November. Even so, this is a tentative time and does not rule out the possibility of further changes.
In short, Intel is trying to publish as early as possible, so as not to miss the end of the shopping holiday, and must be provided to OEM manufacturers as soon as possible to formulate next year's high-end PC planning. If the postponement to the end of the year or even 2012, these two excellent opportunities will be missed, Intel is clearly unacceptable.
On the other hand, even if it can be released in time in November, the new platform we see will not be the way it was initially planned. The Patsburg chipset was originally planned for four levels. The X79, which was used on the desktop, was originally designated Patsburg-D and was later reduced to third-place Patsburg-B. It lost four SATA/SAS 6Gbps interfaces and CPUs. Between the PCI-E 3.0 channel, but now has become the lowest Patsburg-A, no longer support SAS 6Gbps, so compared to the P67, Z68 is not too much.
What is even more depressing is that bad news about the X79 is said to be more than that, but it is still not clear what the problem is.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.
1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.
2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.
3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
