Liquid Cooling, Meeting The Demands Of AI Data Centers


Many Porsche “purists” reflect forlornly upon the 1997, 5th generation, 996 version of the iconic 911 sports car. It was the first year of the water-cooled engine versions of the 911, which had previously been based on air-cooled engines since their entry into the market in 1964. The 911 was also the successor to the popular air-cooled 356. For over three decades, Porsche’s flagship 911 w... » read more

Chip Aging Becoming Key Factor In Data Center Economics


Chip aging is becoming a much bigger concern inside of data centers, where it can impact server uptime, utilization rates, and the amount of energy needed to drive signals and cool entire server racks. Aging in chips is the result of both higher logic utilization and increasing transistor density. This is problematic for data centers, in general, but especially for AI chips where digital log... » read more

Squeezing The Margins


Back in 2016, we looked at the MediaTek Helio X20, the first Tri-Gear mobile SoC. Tri-Gear is a step beyond ARM’s big.LITTLE concept of using two different cores that have unique power and performance characteristics, by adding a third core. The main advantage to this approach is having more core choices to best run workloads at better energy efficiency and performance operating points. At... » read more
