Intel releases quad-core Tigerton processor

IDG News Service - Intel Corp. plans to unveil a version of its Xeon processor on Wednesday that's designed for high-end servers with multiple processors -- setting the stage for a showdown with rival Advanced Micro Devices Inc.'s upcoming quad-core Barcelona chip.

The Xeon 7300 chips, called Tigerton, are the first quad-core processors from Intel designed to be used in servers with four or more processors, a relatively small but lucrative segment of the server market. Previously, the Xeon processor for this segment of the market had two cores, despite the availability of quad-core Xeon chips for single-processor and two-way servers.

The new chips offer significantly better performance compared to their predecessors, Intel's Xeon 5300 chips, said Adesh Gupta, regional platform architecture manager at Intel Asia-Pacific's server platforms group.

"Across the spectrum of different applications, we're seeing really, really good performance," Gupta said.

Benchmarks run by Intel showed significant gains for many enterprise applications, including SAP AG's ERP software, Gupta said. The 7300 series chips can handle roughly 82% more ERP users and 92% more database transactions than the 5300 chips, he said.

The 7300 is part of the Caneland chip package, which also includes Intel's 7300 chip set, known as Clarksboro. The new chip set has four 1,066-MHz interconnects that are linked to an individual processor, helping reduce latency between the processors and main memory.

Caneland is the last release expected from Intel before AMD announces the availability of its Barcelona server chips on Sept. 10. Barcelona is widely expected to offer significant performance increases over AMD's existing dual-core server chips, and should mean tighter competition with Intel in the server space.

Intel will initially offer six versions of Tigerton. At the top of the range is the X7350, a 2.93-GHz chip designed with 8MB of shared on-chip cache and a thermal design power (TDP) of 130 watts. TDP is the highest sustainable level of power for applications that Intel expects to be run on the chip, and the number describes how much heat a system must be able to dissipate from the chip.

Intel is also offering several Xeon 7300 chips with a TDP of 80 watts. The E7340 runs at 2.4 GHz and offers 8MB of shared on-chip cache. The E7330 also runs at 2.4 GHz, but has 6MB of cache. The E7320 and E7310 both have 4MB of shared cache and run at clock speeds of 2.13 GHz and 1.6 GHz, respectively.

Intel will also release a 50-watt version that runs at 1.86 GHz. The L7345 has 8MB of shared on-chip cache and is designed for blade servers and high-density rack servers.
