Specification Differences

The two processors differ in nearly every fundamental specification. The Intel Core i9-11900H has 8 cores and 16 threads, while the AMD Ryzen 5 PRO 4655GE has 6 cores and 12 threads. This core count difference directly explains the multi-core benchmark results.

Clock speeds favor Intel significantly. The i9-11900H runs at a 2.10 GHz base clock and boosts to 4.90 GHz. The AMD part has a higher base clock of 3.30 GHz but a lower boost of 4.20 GHz. The higher base clock on the AMD chip does not compensate for the Intel's superior boost ceiling in burst workloads.

Cache allocation differs substantially. The Intel part has 80 KB of L1 cache per core, 1.25 MB of L2 per core, and 24 MB of shared L3 cache. The AMD part has 64 KB L1 per core, 512 KB L2 per core, and only 8 MB of shared L3. The Intel's 24 MB L3 is triple the AMD's 8 MB, which helps with larger working sets and cache-sensitive applications.

Socket compatibility is entirely different: Intel uses BGA 1787 (mobile), while AMD uses Socket AM4 (desktop). This means the two are not interchangeable in any system. The Intel part targets laptops and mobile workstations, while the AMD part is designed for desktop builds.

PCIe support also differs. The Intel chip supports PCIe Gen 4 with 20 CPU lanes, while the AMD part is limited to PCIe Gen 3 with the same 20 lanes. This gives the Intel platform an advantage for high-bandwidth GPUs and NVMe storage.

Memory support is similar at first glance, with both using DDR4 on a dual-channel bus with 51.2 GB/s bandwidth. However, the AMD part supports ECC memory, which the Intel does not. The AMD also has a larger transistor count at 9,800 million versus no recorded figure for Intel, and a smaller die size at 156 mm² versus 190 mm².

Architecture Differences

The Intel Core i9-11900H is built on the Tiger Lake-H architecture, a mobile-focused design from Intel's 11th generation Core family. It uses a 10 nm process node manufactured at Intel's own fabs. The architecture is designed for high performance in thin-and-light laptops, with a 35 W TDP that allows for aggressive boost behavior within thermal limits.

The AMD Ryzen 5 PRO 4655GE uses the Zen 2 architecture, specifically the Renoir die, and is manufactured on TSMC's 7 nm process. This gives AMD a process node advantage, as 7 nm is more dense than Intel's 10 nm. The AMD chip has 9,800 million transistors packed into a 156 mm² die, while the Intel's 190 mm² die has no recorded transistor count.

The integrated graphics differ: Intel uses UHD Graphics 750, while AMD includes Radeon Vega 7. Both are integrated solutions, but the AMD's Vega architecture typically offers stronger compute capability, though no graphics benchmarks are recorded to confirm this.

The AMD part is a desktop processor on Socket AM4, while the Intel is a mobile processor on BGA 1787. This reflects different design philosophies: the AMD chip prioritizes power efficiency in a fixed desktop environment, while the Intel chip is built to balance performance with thermal constraints in portable systems.

The production status also differs. The Intel Core i9-11900H is end-of-life, meaning it is no longer in active production. The AMD Ryzen 5 PRO 4655GE remains active, suggesting ongoing availability for new system builds.

The Verdict

The data is clear: the Intel Core i9-11900H is the superior processor in every measured benchmark. It wins all 17 head-to-head comparisons, with an average benchmark score of 21,367 against the AMD's 20,900. The percentile ranking confirms this, with Intel at the 75th percentile and AMD at the 74th.

For anyone prioritizing raw computational performance, the Intel Core i9-11900H is the only choice. Its multi-core advantage of 39.2% in Cinebench R23 and 42.3% in PassMark multithread makes it significantly faster for video editing, 3D rendering, software compilation, and data processing. The single-core lead of 16.6% to 39.2% ensures it also excels in everyday tasks and lighter workloads.

The AMD Ryzen 5 PRO 4655GE should be considered only if specific requirements override performance. Its ECC memory support makes it suitable for error-sensitive computing environments. The active production status and desktop socket format may appeal to system builders who need current availability. The lower transistor count and smaller die size suggest better power efficiency, though no power consumption benchmarks are recorded.

However, the performance gap is too large to ignore. The Intel i9-11900H's 210.7% lead in prime number finding and 61% lead in physics simulation are not minor differences; they represent fundamental architectural superiority for compute-heavy tasks. The launch MSRP of $546 for the Intel part reflects its high-end positioning, while the AMD's MSRP is not recorded.

In practical terms, a user choosing between these two should select the Intel Core i9-11900H unless they specifically need ECC memory or require a desktop AM4 socket. The benchmark data offers no scenario where the AMD Ryzen 5 PRO 4655GE comes out ahead, making the Intel part the rational choice for performance-focused builds.
