AMD Ryzen 7 5800XT vs AMD Ryzen 7 8845HS Comparison

The AMD Ryzen 7 8845HS and AMD Ryzen 7 5800XT are both 8-core, 16-thread processors, but they are engineered for entirely different environments. The benchmark data shows a near-even split, with the 8845HS taking 11 wins and the 5800XT taking 10 in direct head-to-head tests. However, the magnitude of those wins is heavily skewed. The 5800XT delivers crushing victories in multi-core rendering tests, while the 8845HS counters with consistent, if smaller, wins in general productivity and math workloads. The average benchmark scores are nearly identical—29955 for the 8845HS versus 29879 for the 5800XT, a delta of just 0.3%—placing both in the 81st percentile of all CPUs. Despite this statistical tie, the data reveals two very distinct performance profiles that cater to different needs.

Head-to-Head Benchmarks

The most significant performance gap in the entire dataset belongs to the 5800XT in Cinebench R23 multi-core, where it scores 23794 against the 8845HS’s 16192. This is a massive 31.9% lead, indicating a substantial advantage in sustained all-core workloads like video rendering or 3D scene compilation. The 5800XT’s dominance extends to the older Cinebench R15 single-core test, where it scores 338 versus 276, a 18.3% margin. This is a curious result, as the 8845HS wins the 3DMark single-thread test by 3.2% (990 vs. 959) and the Passmark single-thread test by 5.7% (3738 vs. 3535). The data suggests the 5800XT is tuned for peak performance in specific legacy rendering instructions, while the 8845HS has a more balanced single-thread advantage in broader workloads.

The 8845HS’s wins, while less dramatic, are numerous. Its largest victory is in Passmark random string sorting, where it scores 41446 versus 35911, a 15.4% lead that indicates superior memory latency handling or sorting algorithm efficiency. It also shows a strong 10.1% advantage in floating-point math (59254 vs. 53808) and a 5.7% lead in extended instructions (25642 vs. 24270). In multi-threaded Passmark tests, the 8845HS wins narrowly, scoring 28498 to the 5800XT’s 28053, a 1.6% margin. The 8845HS also takes the 3DMark 2-thread (1924 vs. 1879) and 4-thread (3690 vs. 3603) tests by 2.4% each, showing better responsiveness in lightly-threaded scenarios.

In the remaining multi-threaded 3DMark tests, the 5800XT asserts its power. It wins the 16-thread test (7683 vs. 7404, a 3.6% lead) and the max-thread test (7680 vs. 7413, a 3.5% lead). The 8-thread test is close, with the 5800XT winning by just 0.9% (6141 vs. 6085). The 5800XT also wins in data compression (352002 vs. 344439, a 2.1% lead), data encryption (21461 vs. 20416, a 4.9% lead), and prime number finding (119 vs. 87, a 26.9% lead). The physics test is essentially a tie, with the 5800XT winning by 0.6% (1355 vs. 1347). The overall picture is clear: the 5800XT is a brute-force performer for heavy, multi-threaded tasks, while the 8845HS is more efficient in mixed and single-threaded workloads.

Architecture Differences

The two processors represent two distinct generations of AMD design. The 8845HS is built on the Zen 4 architecture, codenamed Hawk Point, and utilizes a 4 nm process node from TSMC. It packs 25,000 million transistors into a 178 mm² die. The 5800XT, by contrast, uses the older Zen 3 architecture, codenamed Vermeer, on a 7 nm process node. It has just 4,150 million transistors on a much smaller 74 mm² die. This transistor density difference is key to the 8845HS’s efficiency, though the 5800XT compensates with a higher 105 W TDP versus the 8845HS’s 45 W TDP, explaining the 5800XT’s ability to sustain higher multi-core clock speeds under load.

Cache configurations also differ significantly. Both share a 64 KB L1 cache per core, but the 8845HS has a 1 MB L2 cache per core, double the 512 KB per core on the 5800XT. However, the 5800XT has a much larger 32 MB shared L3 cache, compared to the 8845HS’s 16 MB shared L3 cache. This larger L3 pool likely contributes to the 5800XT’s strong showing in data compression and encryption tests. The memory support is a major divider: the 8845HS supports DDR5 with a theoretical bandwidth of 89.6 GB/s, while the 5800XT is limited to DDR4 with a bandwidth of 51.2 GB/s. This explains the 8845HS’s significant win in random string sorting, a test often sensitive to memory bandwidth.

The 8845HS integrates a Radeon 780M GPU, making it a complete APU solution for mobile systems. The 5800XT has no integrated graphics, requiring a discrete GPU. The 8845HS is built for the AMD Socket FP8 mobile platform, while the 5800XT uses the desktop AMD Socket AM4. The 8845HS also has ECC memory support disabled, whereas the 5800XT has it enabled. The 5800XT is multiplier-unlocked for overclocking, while the 8845HS is locked. Both support PCIe Gen 4 with 20 lanes from the CPU, and both are currently in active production. The 8845HS launched in December 2023, while the 5800XT came later in July 2024.

The Verdict

The data makes a clear verdict: the AMD Ryzen 7 5800XT is the superior choice for pure multi-core rendering and compute-heavy tasks, while the AMD Ryzen 7 8845HS is the better all-rounder for mobile productivity and single-threaded responsiveness. The 5800XT’s 31.9% lead in Cinebench R23 multi-core is a decisive factor for anyone whose primary workload is video rendering, 3D modeling, or other tasks that scale across all cores. Its larger 32 MB L3 cache and higher 105 W TDP allow it to sustain high performance in these scenarios. The 8845HS, however, wins 11 of the 21 head-to-head comparisons, including all Passmark general math and sorting tests. Its higher boost clock of 5.10 GHz and faster DDR5 memory support make it more responsive in everyday applications and less-threaded workloads.

The 5800XT’s single-core Cinebench R15 win (338 vs. 276) is notable, but it is an outlier compared to the 3DMark and Passmark single-thread results, where the 8845HS leads by 3.2% and 5.7%, respectively. The 8845HS’s integrated Radeon 780M GPU is a critical feature for a mobile APU, eliminating the need for a discrete graphics card. The 5800XT’s unlocked multiplier offers overclocking potential for desktop enthusiasts, but this comes at the cost of a 105 W TDP. The 5800XT’s launch MSRP is $249. For a desktop system where raw multi-core power is the only metric, the 5800XT is the data-backed winner. For a laptop or a compact system where efficiency, integrated graphics, and broad workload performance matter, the 8845HS is the clear choice.
