Shanghai Economics 101

April 30, 2009

Before the release of the Istanbul 6-core processor we wanted to preview the CAPEX comparisons we’ve been working on between today’s Opteron (Shanghai) and today’s Nehalem-EP. The results are pretty startling and mostly due to the Nahelem-EP’s limited memory addressing capability. Here are the raw numbers for comparable performance systems (i.e. high-end):

Nehalem-EP Configuration Street $
Shanghai HT3 Configuration Street $
Savings $ Savings %
2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 24GB DDR3/1333 $7,017.69   2P/8C Shanghai, 2393 SE, 3.1GHz, 4.4GT HT3 with 32GB DDR2/800 $5,892.12   $1,125.57 16.04%
2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 48GB DDR3/1066 $7,755.99   2P/8C Shanghai, 2393 SE, 3.1GHz, 4.4GT HT3 with 48GB DDR2/800 $6,352.12   $1,403.87 18.10%
2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 96GB DDR3/1066 $21,969.99   2P/8C Shanghai, 2393 SE, 3.1GHz, 4.4GT HT3 with 96GB DDR2/667 $11,968.72   $10,001.27 45.52%
2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 144GB DDR3/800 $30,029.19   2P/8C Shanghai, 2393 SE, 3.1GHz, 4.4GT HT3 with 128GB DDR2/533 $14,300.92   $15,728.27 52.38%
               
2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 96GB DDR3/1066 $21,969.99   4P/16C Shanghai, 8393 SE, 3.1GHz, 4.4GT HT3 with 96GB DDR2/800 $17,512.87   $4,457.12 20.29%
2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 144GB DDR3/800 $30,029.19   4P/16C Shanghai, 8393 SE, 3.1GHz, 4.4GT HT3 with 192GB DDR2/667 $28,746.07   $1,283.12 4.27%
2 x 2P/8C, Nehalem-EP, W5580 3.2GHz, 6.4GT QPI with 144GB (288GB total) DDR3/800 $60,058.38   1 x 4P/16C Shanghai, 8393 SE, 3.1GHz, 4.4GT HT3 with 256GB DDR2/533 $33,410.47   $26,647.92 44.37%

Even the 4-socket Shanghai 8393SE averages 23% lower implementation cost over Nehalem-EP and produces 16 “real” cores versus 8 “real” cores in the process. Even at 50% theoretical efficiency using Nehalem’s SMT, the 4P Shanghai represents a solid choice in the performance segment. An Istanbul drop-in upgrade spread’s the gulf in capabilities even wider.

Based on today’s economics and the history of seamless vMotion between Opteron processors, 4P/24C Istanbul is a solid will be a no-brainer investment. With 2P/24C and 4P/48C Magny-Cours on the way to handle the “really big” tasks, a Shanghai-Istanbul Eco-System looks like an economic stimulus all its own.
