News Overview
- AMD is rumored to have abandoned its 4nm orders with Samsung Foundry.
- The company is allegedly shifting production of future EPYC CPUs to TSMC’s Arizona facility.
- This move could be motivated by performance or yield concerns with Samsung’s 4nm process or strategic desires related to US-based manufacturing.

In-Depth Analysis
The core of the article revolves around two significant claims. First, AMD is allegedly cancelling its planned use of Samsung Foundry’s 4nm process for at least some products. While the article doesn’t specify all 4nm products, the focus is on EPYC CPUs. This implies that other components like certain APUs might still utilize Samsung’s foundry.
Second, the article states that AMD is shifting EPYC CPU production to TSMC’s new Arizona-based fab. This is a crucial detail because TSMC has multiple manufacturing locations. Producing chips in Arizona could be related to government incentives, improved supply chain security and potentially faster access to products for the North American market. It also signifies a growing importance of US-based semiconductor manufacturing.
The article does not provide specific benchmark data or comparative analysis of performance or yield between Samsung and TSMC’s respective processes. It infers, however, that AMD’s decision is based on factors like these, even though the specifics are currently unknown. The article also mentions that the report is coming from “industry sources” and therefore is still in the realm of rumor.
Commentary
If this rumor proves true, it has several significant implications. First, it suggests that AMD may have encountered issues with Samsung’s 4nm process, potentially related to yields, performance, power consumption, or a combination of these factors. Shifting production to TSMC signals that AMD prioritizes quality and performance over sticking with the original plan.
Secondly, the move to TSMC’s Arizona fab is strategically significant. It demonstrates AMD’s commitment to diversifying its manufacturing base and leveraging US-based production. This could be advantageous in terms of government subsidies and improved supply chain resilience.
From a market perspective, this could solidify AMD’s position as a high-performance CPU provider, but the ramp up of the TSMC Arizona fab could be slow leading to potential supply constraints initially. Intel, with its own foundry ambitions, will be closely watching these developments. A successful TSMC Arizona fab is good news for the US semiconductor industry and could accelerate the growth of other semiconductor businesses in the United States.
