# Architecture Differences

The AMD Ryzen Threadripper 9960X uses the Zen 5 architecture, codenamed Shimada Peak, and belongs to the Ryzen Threadripper generation. It is built on a 4 nm process at TSMC, with 33,260 million transistors and a die size of 4x 70.6 mm². The cache hierarchy uses per-core allocations: 64 KB of L1 per core, 1 MB of L2 per core, and a shared 128 MB of L3 cache. This large L3 cache is typical of a high-core-count desktop processor designed for data-heavy workloads.

The Intel Core Ultra 7 356H uses the Panther Lake architecture, with the same codename for the architecture and the generation listed as Ultra 7 (Panther Lake-H). It is built on a 3 nm process at Intel. No transistor count or die size is listed. The cache hierarchy also uses per-core allocations: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The larger per-core L1 and L2 allocations contrast with the Threadripper’s larger total L3 pool.

The process node difference, 4 nm versus 3 nm, indicates that the Intel part uses a newer manufacturing process. The Threadripper’s transistor count of 33,260 million reflects a large, multi-die design, consistent with its 4x 70.6 mm² die size configuration. The Core Ultra 7 356H’s lack of listed transistor and die data prevents a direct comparison of physical design.

Memory architecture differs in channel count and bandwidth. The Threadripper uses quad-channel memory with 204.8 GB/s bandwidth, while the Core Ultra 7 356H uses dual-channel memory with 115.2 GB/s. ECC support is present on the Threadripper but absent on the Core Ultra 7 356H.

PCIe connectivity differs by lane count. The Threadripper provides 80 Gen 5 lanes from the CPU, while the Core Ultra 7 356H provides 12 Gen 5 lanes from the CPU. This reflects the Threadripper’s desktop workstation role, where many expansion cards and storage devices require direct CPU connections.

Integrated graphics differ completely. The Threadripper has no integrated graphics, so a discrete GPU is required for display output. The Core Ultra 7 356H includes Intel Xe3 Graphics, allowing it to drive displays without a separate graphics card.

The Threadripper has an unlocked multiplier, enabling overclocking. The Core Ultra 7 356H has a locked multiplier, preventing user-controlled frequency adjustments. This aligns with their market positions: the Threadripper targets enthusiasts and workstation builders, while the Core Ultra 7 356H targets mobile systems where power and thermal constraints take priority.

The TDP figures, 350 watts for the Threadripper and 25 watts for the Core Ultra 7 356H, illustrate the design intent. The Threadripper is built for sustained high performance in desktop systems with robust cooling. The Core Ultra 7 356H is built for efficient operation in laptops and compact mobile devices.
