LGA 1155, a new socket for Sandy Bridge

[Flying Black]

Sandy Bridge requires the LGA 1155. Yes, in less than a pin of the interface effect on the compatibility with LGA 1156 socket that has a one year old. The current interface is essentially identical, but has been amended so as to prevent them from mistakenly enter an older generation processor Lynnfield Clarkdale or a new motherboard. Intel says that the transition to socket LGA 1155 could not be avoided. The Sandy Bridge architecture revolves around the idea of integration. Were integrated into the day things were not there before. The result is that the pins have been moved. Intel told us that if it was possible to make a Sandy Bridge LGA 1156, it would, because the company does not gain money from the transition to a new interface - this is only partially true, because Intel sells chipsets for the new cards mother.

I hope that more members must be having some more information to continue.

AMD has had to face the same challenges with the Zambezi, the desktop processor-based architecture Bulldozer out later this year. The company said that it would create processors compatible with socket AM3, assuming you lose some capabilities of the new. The smart move, however, was to simply switch to AM3 +, while maintaining backward compatibility. In conclusion, the LGA 1155 processors are not compatible with existing infrastructure and require an upgrade of the platform. Unfortunately, the chipset P67/H67 not offer capabilities that were not already available on P55 motherboard, then the value of this offer suffers a severe blow if you already have a decent mid-range platform.

The three CPU architecture-based Sandy Brigd are at the top of the overall rankings, followed by the Core i7 875K qualifying speed of 3.6 GHz achieved thanks to the Turbo Boost. Although the 950 Intel Core i7 has a higher frequency and throughput benefits of the DDR3 memory controller with three channels, the highest frequency is 1066 MT / s (compared to 1333 MT / s Lynnfield). Probably does not help the fact that the processor 900 series can come only with the Turbo Boost to 3.3 GHz. The lack of software capable of using all six core clock and lower the base has a generally negative effect on the Phenom II X6 1100T. You see that in some disciplines, such as TV and Movies and Communications, the position of the six-core AMD processor improves. This is not the first time that we write: if a Phenom II covers Core 2, it would be up to it. Against Nehalem is simply outclassed. Compared to Sandy Bridge, there is no game. PCMark Vantage tests, however, is a synthetic.

It was granted the excellent work which was done by Intel. The only drawback is the overclock. I think that the following might be the two main reasons:

1. Intel wants to enjoy these few months that separate us from the Bulldozer architecture of AMD. Once the power of the latter, if Intel will make its processors more attractive suitors by making available unlocked on a wider range of CPU Sandy Bridge. For the moment, can not care less because of the benefits are definitely at the top holds a monopoly from Intel.
2. The second is that maybe Intel is aware that the Bulldozer for improvement, architecture will not be able to fly its Sandy Bridge that plays like it always did before the advent of the Athlon ten years ago.

All this makes me very unsympathetic to Intel and its damned annoying as discounted trade policies but at the same time I inspires admiration for its work.

As you know, the core-based processors Clarkdale presented a year ago were the first to benefit from Intel's manufacturing leadership. Specifically, the dual-core processor was manufactured to 32 nanometers. Intel, however, used the 45-nanometer process for the second day on the package, comprising the memory controller, PCIe controller and graphics. This was the first step towards integrating more functionality into the CPU, but it was not ideal. Graphics performance was better than previous implementations in the chipset. Memory performance, however, decline to Lynnfield and Bloomfield, since the controller was outside by the day. Sandy Bridge with all this logic has been combined, giving Intel the most control over his behavior. For example, the graphics core can now access the last level cache, then the architecture has a mechanism to prevent problems between core and graphics.
