4 nuclear platform 5 for two years to change the interface why

As a key component affecting computer performance, the change of processor interface is considered to be one of the most important forces to drive system upgrades. Between now and 2008, Intel and AMD will join forces to launch at least 5 new processor interfaces---an average of 2.5 a year, perhaps much more. There are indications that the 4-core processor is facing a head-on confrontation. Intel and AMD are planning an interface war against the 4 core processors.

AMD interface 7 months a LGA 775 will be the final curtain call

Of the 5 new processor interfaces to be released, AMD occupies 3 seats. According to a recent AMD-released roadmap, the processor interfaces after AM2 are am2+ and AM3, and the next generation of 4 core Cerberus processor interfaces. It is worth noting that AMD's 3 new processor interfaces are limited to the consumer desktop area only. If you count the mobile and server platforms, then from the introduction of the first socket 754 processor, AMD in 6 years time will replace more than 10 processor interface, the average life of each interface is only 7 months, it is amazing. In addition, we also expect that the Amd-ati "fusion" processor will use what kind of interface?

In contrast, Intel's "passion" for replacing processor interfaces is far less high than AMD. As an interface with PCIe and SATA, LGA 775 witnessed the birth and impending demise of NetBurst, and now continues to exert heat on the Core 2 duo platform. Over the next two years, Intel may only make two changes to the processor interface, replacing LGA 775 with socket B and socket H. Among them, Socket B interface will "eat" desktop, mobile and server three platforms, and the use of the interface of the processor is using the Nehalem framework of the Bloomfield---4 nuclear Bloomfield will replace the Yorkfield of 4 cores, Instead, Yorkfield is now releasing the "2x2" 4 nuclear kentsfield. As for socket H, it replaces socket B.

Socket b stitch Number record AM3 pins may still be 940 stitches

"When the new interface is born, it will give the processor a better performance-power ratio," said an Intel spokesperson after revealing the existence of socket B. In the manufacturing process, the Socket B processor is 45nm, which means it may be smaller in size. However, Socket B has a record 1366 pins, up to 1.76 times times the existing LGA 775 interface. The Socket B processor is added to a number of new designs, based on the theory that the number of pins determines performance. One of the most notable is the integration of the DDR3 memory controller. In addition, the "Hyper-threading" technology will be resurrected on the socket B processor to simulate 4 cores into 8, which may be named HT2.0. Then the FSB architecture will be scrapped, with CSI being replaced. As a North bridge link technology against the AMD HT bus, CSI is described as "significantly improving" the communication efficiency of the processor with other computer components, and can support 8 processor interconnects altogether.

As for AMD, VIA has released a technical preview of the KT960 and KM960 chipsets based on the am2+ platform. One of the most important concerns is that these chipsets support a new HT 3.0 technology, which can be upgraded from 1GHz to 2.6GHz, and the transmission speed from 2gt/s to maximum 5.2gt/s. However, both interfaces, including am2+ and AM3, have no more than 940 pins, equivalent to the number of pins currently on the AM2 interface.

Reducing costs or forcing a painful choice of performance

There is no doubt that the frequent introduction of new processor interface, which is a very helpless for consumers, because the pin has not changed, the estimated am2+ and AM3 can be compatible with AM2. However, using a am2+ or AM3 processor on a AM2 platform costs the loss of new AM2+/AM3 performance, such as HT3.0. In time, am2+ should be the first new processor interface to come, because the Via am2+ chipset is on the market for 2007 years two quarter, while the AM3 product listing time and the am2+ time of the market is "within one year." The first batch of AMD processors using the AM3 platform is likely to be Shanghai. As the strongest server version of Budapest, the Barcelona and Budapest, or KBL, are in front of the Shanghai. As for the Intel socket b/h, the related products are listed in the same time as AM3, after 2008.

Now, the elaboration is clear. If you want to save money, then the 940-pin am2+ (which may only support DDR2) and AM3 is a better option because they may not need to replace the motherboard or accessories. And if you want to pursue more unmatched performance, then socket B should be more worthy of choice, but it will cost a great deal of the economy. In addition, it is said that the interface used for the Cerberus processor will have more pins than "940 stitches", of course it is incompatible with AM3. Have you decided what kind of interface to choose?
