NVIDIA Credits Close Collaboration with TSMC for Kepler's Energy Efficiency
 
Despite the fact that NVIDIA is frantically seeking out other semiconductor foundries for high-volume manufacturing its 28 nm chip designs, and despite some looming irritants, NVIDIA appears to value its relationship with TSMC highly. NVIDIA's senior vice president for Advanced Technology Group Joe Greco, in a recent company blog post, credited close collaboration with TSMC for the stellar energy-efficiency (performance/Watt) figures NVIDIA's Kepler architecture has been able to achieve.

"The advancement that TSMC offered was a new optimized process technology. Kepler is manufactured using TSMC's 28nm high performance (HP) process, the foundry's most advanced 28nm process which uses their first-generation high-K metal gate (HKMG) technology and second generation SiGe (Silicon Germanium) straining," read the blog post. "Using TSMC's 28nm HP process enabled us to reduce active power by about 15 percent and leakage by about 50 percent compared to 40nm, resulting in an overall improvement in power efficiency of about 35 percent (see charts)."

How come the news reader can't link the real source?
