In the very first week of his presidency, Donald Trump vowed to force silicon manufacturing back to the United States by making processors more expensive, a threat he’s repeated since. Is he finally going through with that plan? Trump just announced he’ll putting an enormous 100 percent tariff on chips and semiconductors — unless your…
The Trump administration has excluded “smartphones, computers, and other electronics,” even those imported from China, from tariffs it levied last week, reports Bloomberg. The exemptions don’t free them from all tariffs, though, as the outlet says others from before Trump’s April 9th tariffs still apply. Late last night, US Customs and Border Protection (CBP) updated…
At CES 2025 in Las Vegas, AMD unveiled a slew of new chips destined for devices ranging from desktops to gaming handhelds. AMD is riding high coming into this year’s CES. The company commanded a 28.7% share of the desktop CPU segment in Q3 2024, up 9.6 percentage points compared to the same quarter the…
Graphics processing units (GPUs), the chips on which most AI models run, are energy-hungry beasts. As a consequence of the accelerating incorporation of GPUs in data centers, AI will drive a 160% uptick in electricity demand by 2030, Goldman Sachs estimates. The trend isn’t sustainable, argues Vishal Sarin, an analog and memory circuit designer. After…
The GPUs and other chips used to train AI communicate with each other inside datacenters through “interconnects.” But those interconnects have limited bandwidth, which limits AI training performance. A 2022 survey found that AI developers typically struggle to use more than 25% of a GPU’s capacity. One solution could be new interconnects with much higher…
For months, Intel’s highest-end desktop gaming processors have had a strange tendency to occasionally make games crash — and despite what you might have seen earlier today, Intel says it doesn’t have a final fix for its 13th and 14th Gen Intel Core i9 “Raptor Lake” and “Raptor Lake S” chips just yet. “Contrary to…
Since the passage of the CHIPS and Science Act last August, eight companies have already received more than half of the planned government direct funding. These companies have collectively received $29.34 billion in funding through the CHIPS Act for semiconductor factories across the country. The law, a $280 billion package to support innovation in the…
