Magny-Cours Spotted

Magny-Cours, 12-core Processor

AMD’s next generation “G34” socket Magny-Cours processor was spotted recently by XbitLabs running in AMD’s 4-way test mule platform. We’ve talked about Magny-Cours and socket-G34 before, but had no picture until now. The multi-chip module (MCM) heritage is obvious given it’s rectangular shape.

Critical for AMD will be HT3+DCA2 efficiency and memory bandwidth to counter the apparent success of Nehalem-EP’s SMT technology. Although AMD does not consider hyperthreading to be a viable technology for them, it appears to be working for Intel in benchmark cases.

While seems logical that more “physical” cores should scale better than the “logical” cores provided by SMT, Intel is making some ground of legacy “physical core” systems, demonstrating what appears to be a linear scaling in VMmark. However, Intel has a fine reputation for chasing – and mastering – benchmark performance only to show marginal gains in real-world applications.

Meanwhile, the presure mounts on Instanbul’s successful launch in June with white box vendors making ready for the next wave of “product release buzz” to stimulate sinking sales. Decision makers will have a lot of spreadsheet work to do to determine where the real price performance lies. Based on the high-cost of dense DDR3 and DDR2, the 16-DIMM/CPU advantage is weighing heavily on AMD’s side from a CAPEX and OPEX perspective (DDR2 is already a well-entrenched component of all socket-F platforms).

Up to now, Intel’s big benchmark winners have been the W5580 and X5570 with $1,700 and $1,500 unit prices, respectively. Compounded with high-cost DDR3 dual-rank memory, or reduction in memory bandwidth (which eliminates a significant advantage), the high-end Nehalem-EP is temporarily caught in an economic bind, severely limiting its price-performance suitability.

Tyan Announces Support for Enhanced Opteron

April 28, 2009

Remember our “reveal” of the Tyan S2935-SI back in January as a potential HT3-capable replacement for the GT28 dual-node systems? Well, it’s still not ready, but Tyan has announced 18 motherboard and system updates that “support the enhanced Opteron with HT-3 technology” that are shipping now.

“TYAN has launched 9 new motherboards that support the AMD HyperTransport 3.0 technology that targets various appliances. For scalable and flexible 2-way motherboard solutions, TYAN’s S2912-E, S2915-E, S2927-E, S2932-SI, S2937 and S3992-E are perfect platforms to meet current and future IT server and workstation requirements. TYAN’s S4985-SI, S4989-SI and S4992 motherboards are 4-way solutions that are exceptionally proficient in high density and high performance IT infrastructures.”

We’ve included the table of motherboard and barebones systems affected by the update. Those in blue italics are also part of Tyan’s VMware Ready Certified platform. While these platforms have been user HCL for some time, the elevation to “Certified” status is recognition of the reliability and performance these systems have rendered over the years. It is good news indeed to see their value extended with motherboard and barebones refreshes.

These systems, which SOLORI has been recommending for low-cost VMware Eco-systems for some time, are part of Tyan’s aggressive VMware strategy:

“As a member of the VMware Technology Alliance Partner (TAP) program, TYAN is aggressively utilizing VMware virtualization software technology in TYAN hardware platforms. The nine servers that have recently passed VMware Ready certification for VMware ESX 3.5 and VMware ESX 3.5i include TA26-B2932-E, TA26-B3992-E, TA26-B5397, TX46-B4985-E, VX50-B4985-8P-E, S4985-E, S3992-E, S5397 and S2932-E. VMware System Builder program members can claim equivalency for these systems via the VMware System Builder site at http://www.vmware.com/partners/vip/system-builders/

Most of these systems offer 16-socket+ DIMM configurations (8-DIMM/CPU) enabling up to 64GB/CPU with DDR3/533 support. In order to run DDR2/800 memory, only half of the available slots can be filled (4-DIMM/CPU) allowing for 16GB/CPU of DDR2/800 (4x4GB REG ECC DDR2/800, about 2GB/second increase in bandwidth over DDR2/533 according to benchmarks).
