AMD Ryzen 7 8700G vs Intel Core Ultra 7 155H Comparison

The benchmark data is unambiguous: the AMD Ryzen 7 8700G decisively outperforms the Intel Core Ultra 7 155H across the vast majority of tested workloads. Of the fifteen head-to-head comparisons, the AMD part claims thirteen victories, while the Intel chip manages only two narrow wins. The average benchmark scores reflect this overall trend, with the Ryzen 7 8700G posting a 33089 average against the Intel’s 32697, though both sit at the 83rd percentile among all CPUs.

Head-to-Head Benchmarks

The single most lopsided result is in PassMark’s extended instructions test, where the Ryzen 7 8700G scores 29067 against the Intel’s 16456, a commanding 43.4% advantage. This indicates a substantial gap in SIMD and multimedia instruction throughput, making the AMD part the clear choice for workloads that leverage these instruction sets. Similarly, in PassMark’s random string sorting, the Ryzen 7 8700G posts 46025 versus 31990, a 30.5% margin that suggests superior memory subsystem efficiency for data organization tasks.

Data compression and encryption workloads also heavily favor the AMD chip. The Ryzen 7 8700G achieves 386811 in PassMark data compression, beating the Intel’s 277353 by 28.3%. In data encryption, the score is 22842 versus 16358, a 28.4% advantage. These results point to the Ryzen 7 8700G handling file archiving and secure data processing tasks with considerably more headroom.

The multi-threaded performance picture is consistent. In Cinebench R23 multi-core, the Ryzen 7 8700G scores 17128 against the Intel’s 15028, a 12.3% lead. The PassMark multithread test shows a wider gap at 21.5% (31690 versus 24873). Even in the older Cinebench R15 multi-core benchmark, the AMD part leads by 9% (2693 versus 2450). The Ryzen 7 8700G also wins the integer math test decisively, scoring 103107 versus 86870, a 15.7% margin.

Single-thread performance follows the same pattern. The Ryzen 7 8700G wins PassMark single-thread with 3928 versus 3468, an 11.7% advantage. In Cinebench R23 single-core, the lead is narrower at 4.1% (1817 versus 1743), but the R15 single-core test shows a 10.8% gap (286 versus 255). Floating-point math is a near dead heat, with the AMD part edging out the Intel by a mere 0.2% (63815 versus 63703).

The Intel Core Ultra 7 155H’s two wins are notable for their specificity. In PassMark’s find prime numbers test, the Intel chip scores 113 against the AMD’s 103, a 9.7% advantage. This suggests a particular strength in a niche integer workload. The Intel part also wins the PassMark physics test, scoring 1727 versus 1647, a 4.9% margin. These victories are isolated, however, and do not offset the broader trend of AMD dominance.

Architecture Differences

The two processors represent fundamentally different design philosophies and market targets. The Intel Core Ultra 7 155H is built on the Meteor Lake architecture, using a 7 nm process node from Intel’s own foundry. It is a mobile-focused part, as indicated by its Intel BGA 2049 socket and its 28 W TDP. The AMD Ryzen 7 8700G, in contrast, uses the Zen 4 architecture on a 4 nm process node fabricated by TSMC. It is a desktop processor designed for the AMD Socket AM5, with a significantly higher 65 W TDP.

The core configurations differ substantially. The Intel part packs 16 cores and 22 threads, while the AMD part offers 8 cores and 16 threads. Despite having half the cores, the AMD chip wins most multi-threaded tests, which highlights the efficiency of its Zen 4 cores versus Intel’s hybrid design. The Intel chip has a base clock of 3.80 GHz and a boost clock of 4.80 GHz, while the AMD part operates at a higher 4.20 GHz base and 5.10 GHz boost.

Cache hierarchies also diverge. The Intel Core Ultra 7 155H features 112 KB of L1 cache per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The AMD Ryzen 7 8700G has 64 KB L1 per core, 1 MB L2 per core, and 16 MB of shared L3. The AMD chip’s larger physical footprint is reflected in its 25,000 million transistors on a 178 mm² die, whereas the Intel part’s transistor count and die size are not specified in the data.

Memory bandwidth is another differentiator. The Intel chip supports 89.6 GB/s, while the AMD part is rated at 83.2 GB/s. Both use dual-channel DDR5 memory, though the Intel’s support is noted as depending on the motherboard. PCIe connectivity also differs: the Intel part offers Gen 5 with 8 lanes (CPU only), while the AMD part provides Gen 4 with 20 lanes (CPU only). The integrated graphics are distinct as well, with Intel using Arc Xe-LPG 128EU and AMD featuring the Radeon 780M.

Where Each One Wins

The AMD Ryzen 7 8700G is the clear winner for compute-intensive workloads. Its 43.4% lead in extended instructions, 30.5% lead in random string sorting, and 28.3% lead in data compression make it the superior choice for content creation, video encoding, scientific simulations, and database operations that rely on SIMD throughput and memory bandwidth. The 15.7% advantage in integer math and 21.5% lead in multithread performance further cement its position for software compilation, 3D rendering, and heavy multitasking. The 11.7% single-thread advantage also makes it better for general responsiveness and lightly-threaded applications.

The Intel Core Ultra 7 155H has a very narrow set of strengths. Its 9.7% win in the find prime numbers test suggests an edge in specific number-theoretic algorithms, which could matter for cryptography or certain mathematical software. The 4.9% win in the physics test indicates a slight advantage in that particular simulation workload. However, these are isolated cases. The Intel part’s lower TDP of 28 W versus 65 W indicates it is designed for thermal-constrained mobile environments, but the benchmark data does not show a corresponding performance benefit in any mainstream category.

The Verdict

The data leads to a straightforward conclusion: the AMD Ryzen 7 8700G is the superior processor in nearly every measurable performance category. It wins 13 of 15 head-to-head benchmarks, with the only Intel victories being narrow ones in two specialized tests. The AMD part’s advantages are often substantial, ranging from 4.1% in Cinebench R23 single-core to 43.4% in PassMark extended instructions. Its higher clock speeds, more efficient Zen 4 architecture on a newer 4 nm process, and lower memory bandwidth requirement do not hinder its performance; in fact, they enable it to beat a chip with twice the core count in most multi-threaded workloads.

For users building a desktop system and prioritizing raw performance in content creation, data processing, and general compute tasks, the AMD Ryzen 7 8700G is the clear choice. Its wins in compression, encryption, integer math, and multithreaded tests make it versatile for a wide range of demanding applications. The unlocked multiplier also suggests overclocking potential, which the Intel part lacks.

The Intel Core Ultra 7 155H is a mobile processor with a much lower TDP of 28 W, which is a significant design constraint. Its benchmark results are consistently behind the AMD part, with the gap widening in more complex workloads. Its only wins are in prime number finding and physics simulation, which are narrow niches. The data indicates that if performance is the primary criterion, the AMD Ryzen 7 8700G is the definitive winner. There is no benchmark category where the Intel chip offers a compelling advantage that would justify choosing it over the AMD part on performance grounds alone. The verdict is clear: the AMD Ryzen 7 8700G is the more capable processor.
