Which sandy bridge are affected

For now, however, we'd certainly recommend holding off on buying a new Sandy Bridge computer if the one you want is an affected model. Be respectful, keep it civil and stay on topic. We delete comments that violate our policy , which we encourage you to read.

The company is continuing to ship Sandy Bridge processors, while the 6-Series chipset has been put on hold, Smith said. But the chipset and Sandy Bridge processors are paired in many PCs, so the chipset halt could indirectly affect Sandy Bridge volumes, Intel officials acknowledged. End-user laptops with dual-core Sandy Bridge chips were expected to launch in a few weeks and Smith said those launches may be delayed.

The second-generation Core processors based on the Sandy Bridge microarchitecture include a number of improvements over their predecessor. The new Core processors for the first time integrate a CPU and graphics processor on one chip, which helps deliver better graphics and application performance.

Intel said that full-year revenue is not expected to be materially affected by the issue. This is a big hit for Intel, which is known for flawless chip designs and was pinning hopes on Sandy Bridge chips to deliver close to a third of the revenue during fiscal Intel announced on Monday that it was recalling its Intel 6 series chipset.

This chipset is utilized in computers powered by the next generation Core i5 and Core i7 processor. Intel has issued a silicon fix and is re-manufacturing this chipset.

The first batch of improved chipsets will arrive in late February, and manufacturing should be in full swing by April. Intel has said a fault in one of its support chips will need "a silicon fix," which has led to downgraded revenue expectations for the first quarter of The company discovered ports within the affected chipsets, which are used in PCs with the company's latest generation Sandy Bridge processors, could degrade over time.

Intel stressed there were no issues with the Sandy Bridge chip design and no other processors were affected by the Cougar Point problem. Only those support chips shipped after 9 January are affected and Intel believes "relatively few consumers" have been affected.
