Architecture Differences

The two processors are built on fundamentally different architectures. The AMD Ryzen 7 PRO 5755G uses the Zen 3 architecture, codenamed Cezanne, which is a mature design from the 5000 series. It is manufactured on a 7 nm process node by TSMC, with a die size of 180 mm² and 10,700 million transistors. The Intel Core Ultra 7 356H, by contrast, uses the Panther Lake architecture, codenamed Panther Lake-H, from the Core Ultra Series 3. It is manufactured on a 3 nm process node by Intel.

Cache layouts differ significantly. The AMD part has 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of L3 cache. The Intel part has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. This gives Intel a larger total cache footprint, particularly at the L1 and L2 levels, which contributes to its superior performance in memory-latency-sensitive benchmarks.

The integrated graphics differ as well. AMD uses the Radeon Vega 8, a known quantity from the Cezanne generation. Intel uses the Intel Xe3 Graphics, a newer design that benefits from the Panther Lake architecture's improved power efficiency. The PCIe support also differs: AMD offers PCIe Gen 3 with 16 lanes (CPU only), while Intel offers PCIe Gen 5 with 12 lanes (CPU only). The newer PCIe standard on the Intel part provides higher bandwidth for connected devices, though the lane count is lower.

The memory architecture is another major divergence. AMD supports DDR4 memory on a dual-channel bus. Intel supports DDR5 and LPDDR5X on a dual-channel bus. The memory bandwidth figures are 51.2 GB/s for AMD and 115.2 GB/s for Intel. This doubling of bandwidth is a direct result of the newer memory standard and is reflected in the benchmark scores for data compression and encryption, which are heavily memory-bound.

Specification Differences

The core and thread counts are a key differentiator. The AMD Ryzen 7 PRO 5755G has 8 cores and 16 threads, while the Intel Core Ultra 7 356H has 16 cores and 16 threads. The base clock for AMD is 3.80 GHz, which is significantly higher than Intel's 1.90 GHz. The boost clocks are closer, with AMD at 4.60 GHz and Intel at 4.70 GHz. The thermal design power (TDP) differs substantially: AMD is rated at 65 watts, while Intel is rated at 25 watts. This lower TDP for Intel is notable given its higher core count and benchmark scores.

The socket types are incompatible. AMD uses the AM4 socket, while Intel uses the BGA 2540 socket. The production status for both is listed as Active. The release dates show AMD launching on 2024-09-04 and Intel on 2026-01-04. Neither processor has a recorded launch MSRP.

Memory support is exclusive to each platform. AMD supports DDR4, while Intel supports DDR5 and LPDDR5X. Both use dual-channel memory buses, but the bandwidth figures are 51.2 GB/s for AMD and 115.2 GB/s for Intel. Neither processor supports ECC memory. The PCIe lanes are Gen 3 for AMD and Gen 5 for Intel, with lane counts of 16 and 12 respectively.

The cache specifications differ in structure. AMD uses a per-core layout with 64 KB L1 and 512 KB L2, plus a 16 MB L3. Intel uses 192 KB L1 and 2.5 MB L2 per core, plus 18 MB shared L3. The transistor count and die size are only recorded for AMD: 10,700 million transistors on a 180 mm² die. No transistor count or die size is recorded for Intel.

Where Each One Wins

The Intel Core Ultra 7 356H is the clear winner in raw computational throughput. Its victories span data compression, data encryption, extended instructions, prime number finding, floating-point math, multithreaded performance, physics simulation, random string sorting, and single-threaded tasks. For users running parallel workloads, scientific simulations, or content creation tools that rely on floating-point math, the Intel part delivers consistently higher scores, often by margins of 20% to 80%.

The AMD Ryzen 7 PRO 5755G wins only in integer math, scoring 90270 versus Intel's 83111. This 8.6% advantage suggests that for workloads dominated by integer arithmetic, such as certain types of database operations, financial calculations, or legacy software optimized for Zen 3, the AMD part holds a measurable edge. However, this is a narrow use case. The AMD processor also has a higher base clock (3.80 GHz vs 1.90 GHz), which can benefit latency-sensitive tasks that do not scale across cores but depend on raw clock speed for responsiveness.

The market segments also define the appropriate use cases. AMD is categorized as a Desktop processor, while Intel is categorized as Mobile. This means the AMD chip is suited for stationary builds where the 65-watt TDP is acceptable, while the Intel chip is designed for laptops and portable devices where the 25-watt TDP is a critical advantage. The Intel part's higher memory bandwidth and newer PCIe Gen 5 support make it more future-proof for mobile systems with fast SSD and external GPU connectivity.

The Verdict

The benchmark data points to the Intel Core Ultra 7 356H as the superior processor for almost all measured tasks. It wins 10 of 11 head-to-head tests, often by wide margins, while consuming less power (25 watts vs 65 watts) and using a more advanced 3 nm process node. The Intel part's higher single-thread score (4072 vs 3366), higher multithread score (33978 vs 23858), and massive lead in floating-point math (103128 vs 50778) make it the obvious choice for users who prioritize performance across a broad range of applications.

The AMD Ryzen 7 PRO 5755G is the better choice only for workloads that are specifically integer-math intensive, where its 8.6% advantage in that single test could justify its selection. Its higher base clock and established AM4 platform may appeal to users with existing DDR4 infrastructure or those who prefer a desktop-oriented processor with a 65-watt TDP. However, the overall average benchmark score (49196 for AMD vs 41215 for Intel) does not tell the full story, as the Intel part's newer architecture and lower power envelope make it the more compelling option for mobile and power-constrained environments. The data confirms that for general-purpose computing, the Intel Core Ultra 7 356H is the stronger performer, while the AMD Ryzen 7 PRO 5755G is a niche specialist for integer-heavy desktop tasks.
