Intel announces "Nehalem" - 8-core CPU with mem-controller + graphic capabilities
http://money.cnn.com/news/newsfeeds/...7_FORTUNE5.htm SAN FRANCISCO (Dow Jones) - A major computer-chip redesign at Intel Corp. will likely put more pressure on smaller rival Advanced Micro Devices Inc., industry observers said Thursday. Intel (INTC) is working on a new computer chip called Nehalem that will integrate the microprocessor -- the central processing unit in a PC - with the chip's memory controller. Intel currently uses external memory in separate products known as chipsets that fetch data from different parts of the computer. The Nehalem chip should help Intel relieve performance bottlenecks in its current family of chips, analysts said. AMD chips have had the two features combined for several years now, a technology edge that has helped the company take market share from its larger rival. "Nehalem appears to be a truly revolutionary platform and addresses AMD's latest claim of differentiation," wrote Deutsche Bank analyst Ross Seymore. In midday trading Thursday, AMD shares fell 2.5% to $13.05. Intel lost 0.4% to $18.48. Intel plans to ship the Nehalem chip in 2008. It said customers will be able to choose from single-core to eight-core versions, which are the equivalent of eight electronic brains on a single chip. Intel also said it plans to add some graphics capability onto the chip. AMD is currently working on a similar design associated with its $5.4 billion acquisition of ATI Technologies last fall. AMD is facing increased pressure from Intel, which wants to win back market share it's lost the past three years. To carry out that plan, Intel intends to release several new chip lines through 2010. Since last summer, Intel has unleashed 40 new microprocessors for desktops, laptops, and servers. In 2003, AMD (AMD) began to combine the memory controller with the central processor when the company launched its Opteron server chip. The processor, which uses so-called direct connect architecture, rejuvenated AMD's fortunes, helping it dent Intel's worldwide market share and forcing Intel to admit it made some technological missteps. AMD now commands 25% of the world's microprocessor market, up significantly from what it had before it rolled out the Opteron line. Its encore to Opteron is called Barcelona, which is slated to hit the market by mid-summer. Barcelona is the chipmaker's first major design refresh in more than three years. Intel's plans are "further validation that their current architecture will not be competitive with Barcelona until they make this transition that we showed the industry in 2003," AMD Vice President Randy Allen said in a prepared statement. Barcelona will compete with a quad-core processor Intel launched this past November. AMD said its product won't force customers to make "wholesale infrastructure changes in order to achieve incremental performance gains." Last month, AMD warned it won't meet its previous first-quarter financial targets as it struggles with weaker prices for its microprocessors and supply problems. "It is becoming obvious that AMD's only weapon, outside of Barcelona, is price," wrote Doug Freedman, analyst at American Technology Research. He projects Intel will recapture market share in the server space - where AMD has hurt Intel the most - and concede less profitable parts of the PC market to AMD. |

The pros and cons of external memory controllers have been discussed here before, and I won't rehash, but the bottom line is that any assumption that integrated or external memory control is "better" ignores the fact that is a tradeoff. The IBM maximum performance chipset discussed about two years ago is a case in point, providing higher bandwidth and lower latency through increased complexity in the memory subsystem. As I recall, it was multiway interleave, integrated L3 cache, and CPU to CPU cache bypass (not through main memory). And I admit I didn't dig back in the archives for the details, either. -- Bill Davidsen He was a full-time professional cat, not some moonlighting ferret or weasel. He knew about these things. |
