Architecture Differences

The two processors come from different generations and process nodes. The 8845HS is built on Zen 4 architecture with the Hawk Point codename, using a 4 nm process from TSMC. It packs 25,000 million transistors on a 178 mm² die. The 5800X uses Zen 3 architecture with the Vermeer codename, on a 7 nm process, with 4,150 million transistors on a 74 mm² die. This process advantage gives the 8845HS a higher boost clock (5.10 GHz vs 4.70 GHz) and better power efficiency, reflected in its 45 W TDP versus the 5800X's 105 W.

Cache configurations differ significantly. The 8845HS has 1 MB of L2 cache per core, while the 5800X has 512 KB per core. However, the 5800X has 32 MB of shared L3 cache, twice the 16 MB on the 8845HS. This larger L3 cache likely contributes to the 5800X's wins in prime number finding and encryption, which are cache-sensitive. Memory support also diverges: the 8845HS uses DDR5 with a dual-channel bus and 89.6 GB/s bandwidth, while the 5800X uses DDR4 with 51.2 GB/s. The 8845HS also includes a Radeon 780M integrated GPU, whereas the 5800X has none. ECC memory is supported on the 5800X but not on the 8845HS. The 8845HS uses AMD Socket FP8, while the 5800X uses AM4. The 8845HS is a mobile part, and the 5800X is a desktop part.

Specification Differences

The two processors differ in several key specifications. The 8845HS has a boost clock of 5.10 GHz, while the 5800X reaches 4.70 GHz. TDP is 45 W for the 8845HS and 105 W for the 5800X. The socket is FP8 for the 8845HS and AM4 for the 5800X. Architecture is Zen 4 versus Zen 3, and the process node is 4 nm versus 7 nm. Transistor count is 25,000 million versus 4,150 million, and die size is 178 mm² versus 74 mm². L2 cache per core is 1 MB versus 512 KB, and L3 cache is 16 MB versus 32 MB. Memory support is DDR5 versus DDR4, with bandwidth of 89.6 GB/s versus 51.2 GB/s. ECC memory is not supported on the 8845HS but is on the 5800X. Integrated graphics are present on the 8845HS (Radeon 780M) and absent on the 5800X. The market segment is mobile versus desktop. Release dates are 2023-12-05 for the 8845HS and 2020-11-04 for the 5800X. The 5800X had a launch MSRP of $449. The multiplier is unlocked on the 5800X but locked on the 8845HS. Part numbers also differ.

The Verdict

The benchmark data is unambiguous: the 8845HS is the faster processor in the majority of tests. It wins 16 of 23 head-to-head comparisons, including the most modern and relevant workloads. Its single-thread advantage is substantial, with a 12.4% lead in Cinebench R23 single-core and an 8.5% lead in PassMark single-thread. In multi-threaded tasks, it leads by 4.6% in Cinebench R23 multi-core and 10.7% in Geekbench multi-core. The 8845HS also dominates in floating point math and random string sorting, with margins of 12.6% and 17.1% respectively. For general productivity, content creation, and single-threaded applications, the 8845HS is the clear choice.

The 5800X is not without merit. It wins in prime number finding by 29.8%, data encryption by 3.7%, and data compression by 0.3%. It also takes the 3DMark 16-thread and max-thread tests, along with Cinebench R15 multi-core and PassMark physics. These wins suggest the 5800X is better suited for workloads that rely on large L3 cache and specific integer operations, such as prime number generation and encryption. It also offers ECC memory support and an unlocked multiplier, which are valuable for desktop users who need those features. However, the 5800X is a desktop part with a 105 W TDP and no integrated graphics, while the 8845HS is a mobile chip with a 45 W TDP and a Radeon 780M iGPU. The data shows the 8845HS is the stronger overall performer in modern benchmarks.

Where Each One Wins

The 8845HS wins in 3DMark 2-thread, 4-thread, and 8-thread tests, as well as 3DMark single-thread. It also takes Cinebench R23 multi-core and single-core, Geekbench multi-core and single-core, PassMark extended instructions, floating point math, integer math, multithread, random string sorting, and both PassMark single-thread entries. These wins cover a broad range of tasks, from office productivity to scientific computing. The 8845HS is particularly strong in memory-bandwidth-sensitive workloads, thanks to its DDR5 support and 89.6 GB/s bandwidth, and in single-threaded applications where its 5.10 GHz boost clock and Zen 4 architecture shine.

The 5800X wins in 3DMark 16-thread and max-thread, Cinebench R15 multi-core, PassMark data compression, data encryption, find prime numbers, and physics. These are mostly legacy multi-threaded tests or workloads that benefit from its 32 MB L3 cache. The 5800X's 29.8% lead in prime number finding is its largest margin, and its 3.7% edge in encryption shows a clear advantage in cryptographic tasks. For users who run prime number searches, encryption, or older multi-threaded benchmarks, the 5800X is the better option. For everything else, the 8845HS is the superior choice based on the recorded data.
