AMD Ryzen 5 8500GE vs Intel Core Ultra 5 125H Comparison

The AMD Ryzen 5 8500GE and Intel Core Ultra 5 125H are both mobile processors that land in the same performance tier, yet they achieve parity through entirely different means. The AMD chip wins 11 of 17 head-to-head benchmarks, but the Intel part takes the overall PassMark multithread crown by a razor-thin margin and dominates in floating-point workloads. Benchmark results indicate the Ryzen 5 8500GE is the stronger all-around performer for most tasks, with a decisive edge in single-threaded and render workloads, while the Core Ultra 5 125H counters with superior math throughput and physics simulation.

Head-to-Head Benchmarks

The most dramatic gap appears in Cinebench R23 multi-core, where the Ryzen 5 8500GE scores 17,940 against the Intel's 12,804.5 — a 40.1% advantage. This is the largest delta in the entire comparison and signals a clear win for AMD in heavily threaded rendering workloads. The single-core R23 result is even more lopsided: the AMD chip posts 2,532 versus 1,647.5, a 53.7% lead. These two numbers alone define the matchup: the Ryzen 5 8500GE is categorically faster in Cinebench.

The story repeats in Cinebench R20, where the AMD chip wins both multi-core (7,534 vs 7,161, a 5.2% edge) and single-core (1,063 vs 1,010, also 5.2%). However, Cinebench R15 multi-core flips the script: the Intel part scores 2,021.5 versus 1,808, a 10.6% victory. This inconsistency across Cinebench versions suggests the Intel chip scales differently depending on the workload's threading characteristics, but the modern R23 result is far more representative of current render workloads.

PassMark results paint a mixed picture. The Ryzen 5 8500GE wins single-thread (3,914 vs 3,399, a 15.2% lead), extended instructions (17,962 vs 13,749, a 30.6% lead), random string sorting (29,501 vs 27,435, a 7.5% lead), and data compression (246,397 vs 236,209, a 4.3% lead). It also edges out the Intel chip in PassMark multithread by a hair: 21,135 vs 21,100, a 0.2% margin. That near-tie in the aggregate multithread score is remarkable given the Intel part has 14 cores and 18 threads versus the AMD's 6 cores and 12 threads.

The Intel Core Ultra 5 125H wins six benchmarks, and its victories are concentrated in math-heavy tasks. It leads floating-point math by 24.4% (51,670 vs 39,065), integer math by 10.5% (69,986 vs 62,666), physics by 20.1% (1,439 vs 1,150), and find prime numbers by 10.2% (88 vs 79). It also wins data encryption by a negligible 0.4% (14,251 vs 14,197) and Cinebench R15 multi-core as noted. The physics result is particularly notable, as it suggests the Intel architecture handles rigid-body and particle simulations more efficiently.

Q: Which processor has the higher boost clock?

A: The AMD Ryzen 5 8500GE has a boost clock of 5.00 GHz, while the Intel Core Ultra 5 125H boosts to 4.50 GHz. The AMD chip also has a lower base clock at 3.40 GHz versus 3.60 GHz.

Q: Do both processors support ECC memory?

A: No. The AMD Ryzen 5 8500GE supports ECC memory, while the Intel Core Ultra 5 125H does not.

Architecture Differences

The two processors represent fundamentally different design philosophies. The AMD Ryzen 5 8500GE uses the Zen 4 architecture on the Phoenix2 codename, built on a 4 nm process at TSMC with 20,900 million transistors on a 137 mm² die. The Intel Core Ultra 5 125H uses the Meteor Lake architecture, built on a 7 nm process at Intel with no transistor count or die size listed. This process advantage helps explain the AMD chip's superior efficiency in single-threaded tasks.

Cache hierarchies differ substantially. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 112 KB of L1 per core, 2 MB of L2 per core, and 18 MB of shared L3. The larger per-core L1 and L2 caches on the Intel part likely contribute to its strong math performance, while the AMD chip's lower-latency Zen 4 cores win in latency-sensitive single-thread tests.

Memory support is another key differentiator. Both support DDR5 with dual-channel memory buses, but the Intel chip has higher memory bandwidth at 89.6 GB/s versus the AMD's 83.2 GB/s. The AMD part supports ECC memory, the Intel part does not. PCIe capabilities also differ: the AMD chip uses Gen 4 with 14 CPU-only lanes, while the Intel chip uses Gen 5 (lane count not specified in the data).

The integrated graphics differ as well. The AMD chip pairs with a Radeon 740M, while the Intel chip uses Arc Xe-LPG 96EU. The AMD chip has an unlocked multiplier, making it overclockable, while the Intel chip is locked. The Intel part has a stated launch MSRP of $375; the AMD part has no listed launch MSRP.

The Verdict

The data points decisively toward the AMD Ryzen 5 8500GE for most users. It wins 11 of 17 benchmarks, including all single-thread tests, the two most recent Cinebench multi-core versions, and the PassMark multithread score. The 40.1% lead in Cinebench R23 multi-core is a dominant result that outweighs the Intel chip's wins in math-heavy PassMark tests. The AMD part achieves this with fewer cores (6 vs 14) and threads (12 vs 18), highlighting the efficiency of the Zen 4 architecture on a 4 nm process.

The Intel Core Ultra 5 125H is not without merit. It wins floating-point math by 24.4%, integer math by 10.5%, and physics by 20.1%. For workloads that are heavy on mathematical computation — scientific simulations, physics engines, or number-crunching algorithms — the Intel chip is the better choice. Its higher memory bandwidth (89.6 GB/s vs 83.2 GB/s) and larger caches support this strength.

However, the AMD chip's advantages are more broadly applicable. Single-thread performance is critical for everyday responsiveness, and the AMD part wins by 15.2% in PassMark single-thread. The 30.6% lead in extended instructions suggests better SIMD and vector processing efficiency. The 53.7% margin in Cinebench R23 single-core is an outlier that suggests the Intel chip has a significant weakness in that specific workload.
