AMD Ryzen 7 5700G vs Intel Core Ultra 5 125H Comparison

Head-to-Head Benchmarks

The AMD Ryzen 7 5700G takes the overall win count in direct comparisons, with 9 wins against 6 for the Intel Core Ultra 5 125H. However, the nature of those wins tells a more nuanced story than the raw tally. The AMD part dominates heavily in throughput-oriented tasks, while the Intel chip posts decisive victories in specific single-thread and specialized workloads.

The largest margin in the entire comparison belongs to the Intel Core Ultra 5 125H in the PassMark find prime numbers test. It scores 88 against the AMD's 59, a 49.2% advantage. This is a massive gap that points to architectural efficiency in integer-heavy, latency-sensitive loops. The Intel chip also wins PassMark physics with 1439 versus 999, a 44% lead, which is notable given that physics simulations often scale with core count and memory bandwidth.

On the AMD side, the biggest wins are equally dramatic. The Ryzen 7 5700G leads by 37.1% in PassMark extended instructions (21847 vs 13749), by 29.9% in data encryption (20325 vs 14251), and by 25.8% in data compression (318262 vs 236209). These are large, consistent advantages in workloads that benefit from high per-core throughput and efficient SIMD execution. The AMD chip also wins integer math by 23.5% (91541 vs 69986) and random string sorting by 17.8% (33384 vs 27435).

In multi-threaded renders, the two processors are nearly inseparable. Cinebench R23 multi-core shows AMD at 12830.5 against Intel's 12804.5, a negligible 0.2% difference. Cinebench R15 multi-core is similarly close, with AMD at 2107 and Intel at 2021.5, a 4.1% gap. The AMD chip also leads PassMark multithread by 13.6% (24419 vs 21100), but the Cinebench results suggest that for typical rendering workloads, the difference is small.

Single-core results split by test generation. In Cinebench R23 single-core, the Intel Core Ultra 5 125H wins by 10.3% with 1647.5 against 1494. In PassMark single-thread, the Intel chip wins by 3.5% (3399 vs 3283). However, in Cinebench R15 single-core, the AMD part edges ahead by 0.6% (242.5 vs 241). The floating point math test is essentially a tie, with Intel at 51670 and AMD at 51296, a 0.7% margin for Intel.

Where Each One Wins

The AMD Ryzen 7 5700G is the clear choice for data-heavy and encryption-heavy workloads. Its wins in data compression, encryption, extended instructions, integer math, and random string sorting show a pattern: this chip excels when the task involves moving or transforming large volumes of data. The multithread score of 24419 against 21100 further reinforces that AMD's design favors sustained parallel throughput across all cores.

The Intel Core Ultra 5 125H wins in areas that reward lower latency and higher single-thread efficiency. The 49.2% lead in prime number finding and the 44% lead in physics are both significant. Prime number finding is notoriously sensitive to branch prediction and integer unit efficiency, while physics scores often depend on how well the scheduler handles mixed workloads. Intel's 10.3% win in Cinebench R23 single-core also suggests that for lightly threaded applications, the Ultra 5 125H has the edge.

For rendering specifically, the two are effectively tied. Cinebench R23 multi-core differs by only 0.2%, which is within run-to-run variance. Users who primarily render with Cinebench-style workloads will not see a meaningful difference. The AMD chip wins Cinebench R15 multi-core by 4.1%, but that test is older and may not reflect modern rendering engines.

The split is therefore: AMD for compression, encryption, integer-heavy math, and general multithreaded productivity; Intel for physics simulation, prime number calculation, and newer single-thread benchmarks. Floating point math and Cinebench multi-core are neutral ground.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core Ultra 5 125H uses Meteor Lake architecture, built on a 7 nm process at Intel's own foundry. It packs 14 cores and 18 threads, which indicates a hybrid design mixing performance and efficiency cores. The AMD Ryzen 7 5700G uses Zen 3 architecture, also on a 7 nm node, but fabricated by TSMC. It has 8 cores and 16 threads, all of which are full performance cores.

Cache layouts differ substantially. Intel allocates 112 KB of L1 per core and 2 MB of L2 per core, with 18 MB of shared L3. AMD uses 64 KB of L1 per core and 512 KB of L2 per core, with 16 MB of shared L3. The Intel design has more L2 per core, which can help with frequently accessed data, while AMD's smaller L2 is compensated by a more uniform core design.

Memory support is a major divider. The Intel chip uses DDR5 with a dual-channel bus and 89.6 GB/s of bandwidth. The AMD chip uses DDR4 with a dual-channel bus and 51.2 GB/s of bandwidth. That is a 75% bandwidth advantage for Intel, which explains why the AMD chip still wins many memory-sensitive tests despite lower theoretical bandwidth. The AMD part's older platform may limit its ability to exploit high-bandwidth memory.

PCIe generation also differs. Intel supports Gen 5, while AMD is limited to Gen 3 with 16 lanes on the CPU. Integrated graphics are another split: Intel uses Arc Xe-LPG with 96 execution units, while AMD uses Radeon Vega 8. The AMD chip has a larger physical footprint at 180 mm² with 10,700 million transistors, while Intel's die size is not recorded in the database.

The AMD part is socketed on AM4 and has an unlocked multiplier, making it overclockable. The Intel part is BGA 2049, soldered to the motherboard, and locked. The AMD chip has a 65 W TDP, while the Intel chip is rated at 28 W, reflecting its mobile orientation. Intel's release date is December 2023, while AMD's is April 2021.

The Verdict

The data points to a clear division of use cases. The AMD Ryzen 7 5700G is the stronger all-round performer for desktop productivity, especially in tasks that involve data transformation. Its wins in compression, encryption, integer math, and multithreaded workloads give it a broader applicability. The 13.6% lead in PassMark multithread and the 23.5% lead in integer math are substantial margins that will show up in daily use.

The Intel Core Ultra 5 125H is the better choice for specific workloads that reward its architecture. The 49.2% win in prime number finding and the 44% win in physics suggest that applications with irregular control flow or simulation-heavy logic will run noticeably better on Intel. Its 10.3% lead in Cinebench R23 single-core also makes it preferable for lightly threaded tasks that use newer instruction paths.

For rendering, pick either. The 0.2% difference in Cinebench R23 multi-core is noise. For data-heavy workloads, pick AMD. For physics and branch-heavy integer tasks, pick Intel. The AMD chip's unlocked multiplier and AM4 socket make it more flexible for desktop builders, while the Intel chip's 28 W TDP and mobile BGA socket suit thin-and-light systems. Both parts sit at the 79th percentile among all CPUs, and their average benchmark scores differ by only 1.7% (27507 vs 27051), so the overall performance tier is identical.
