AMD Ryzen 5 PRO 8540U vs Intel Core 7 350 Comparison

The Verdict

The AMD Ryzen 5 PRO 8540U and Intel Core 7 350 are both 6-core mobile processors, but the benchmark data separates them into distinct roles. The AMD part wins 11 of 17 head-to-head tests, while the Intel part wins 6. The average benchmark score tells the broader story: the Ryzen 5 PRO 8540U records 23709, placing it in the 76th percentile of all CPUs, while the Intel Core 7 350 averages 17779, sitting in the 71st percentile.

The Ryzen 5 PRO 8540U is the pick for multi-threaded workloads, rendering, and data-heavy tasks. Its Cinebench R23 multicore score of 15456 versus 8030 for the Intel part is a 92.5% advantage, the largest gap in the entire comparison. The AMD chip also leads in integer math by 68.2%, data compression by 43.7%, and random string sorting by 43.9%. For users running compiled workloads, database operations, or parallel rendering, the AMD processor is clearly the stronger option.

The Intel Core 7 350 has its own territory. It wins in Cinebench R15 singlecore by 25%, Passmark single-thread by 13.1%, floating point math by 18.6%, physics by 16.2%, and prime number finding by 38.3%. Those wins point to workloads that favor higher per-core frequency bursts or specific math instruction patterns. The Intel part also has a lower 15 W TDP versus 28 W for the AMD chip, which matters for fanless or ultra-light chassis designs where sustained multi-core loads are secondary.

The database positions each chip near different rivals. The Ryzen 5 PRO 8540U sits within 1.1% of the AMD Ryzen 7 8840U and 0.7% of the Intel Core 3 100HL. The Intel Core 7 350 matches closely with the AMD Ryzen 5 3600XT (0.6% faster) and the Intel Core 5 120U (0.7% faster). This confirms the AMD part belongs in a higher performance tier despite both having six physical cores.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 PRO 8540U uses Zen 4 architecture on Hawk Point, built on a 4 nm TSMC process with 20,900 million transistors on a 137 mm² die. It offers 6 cores and 12 threads, meaning simultaneous multithreading is enabled. Each core has 64 KB of L1 cache, 1 MB of L2 cache, and the chip shares 16 MB of L3 cache. It supports DDR5 memory in dual-channel configuration with 89.6 GB/s bandwidth and ECC memory support.

The Intel Core 7 350 uses Wildcat Lake, built on a 3 nm Intel process. It also has 6 cores but only 6 threads, so no hyper-threading on this part. Cache structure is different: each core gets 192 KB of L1 and 2.5 MB of L2, but the shared L3 is only 6 MB. Memory support includes DDR5 and LPDDR5X, but the bus is single-channel with 59.7 GB/s bandwidth. ECC memory is not supported.

The memory subsystem is a major architectural separation. The AMD part has dual-channel memory with roughly 50% more theoretical bandwidth (89.6 GB/s versus 59.7 GB/s). That bandwidth advantage shows up in the data compression and random string sorting results. The Intel part compensates with a larger per-core L2 cache (2.5 MB versus 1 MB), which may explain its lead in prime number finding and floating point math, workloads that fit in cache.

Connectivity also differs. The AMD chip exposes Gen 4 PCIe with 14 lanes from the CPU, while the Intel chip has Gen 4 PCIe with only 6 lanes. For a mobile processor, the AMD part offers more headroom for discrete GPUs or multiple NVMe drives. The integrated graphics also differ: AMD uses Radeon 740M, Intel uses Xe3 Graphics with 2 Xe cores. The Intel chip has a later release date in the database, 2026-04-15 versus 2024-04-15 for the AMD part.

Head-to-Head Benchmarks

The Cinebench suite paints a clear picture. In R15 multicore, the AMD chip scores 1557 against 1220 for Intel, a 27.6% lead. In R20 multicore, AMD leads 6491 to 5373, a 20.8% margin. The R23 multicore result is the standout: 15456 versus 8030, a 92.5% advantage. That near-doubling comes from the AMD part having 12 threads versus 6, plus the dual-channel memory feeding those threads.

Single-core Cinebench results are mixed. In R15 singlecore, the Intel part wins 292 to 219, a 25% lead. But in R20 singlecore, the AMD chip wins 916 to 758, a 20.8% margin. In R23 singlecore, AMD wins again, 2182 to 2046, a 6.6% edge. The R15 result appears to be an outlier relative to the other two single-core tests, where the AMD chip either wins or stays close.

Passmark tests show the workload split. The AMD part dominates data compression (205703 versus 143123, up 43.7%), data encryption (12319 versus 10933, up 12.7%), extended instructions (15410 versus 12045, up 27.9%), integer math (56738 versus 33734, up 68.2%), multithread (18218 versus 15170, up 20.1%), and random string sorting (24797 versus 17238, up 43.9%).

The Intel part wins in floating point math (42809 versus 34865, up 18.6%), physics (1173 versus 983, up 16.2%), prime number finding (107 versus 66, up 38.3%), and single-thread tests (4100 versus 3563, up 13.1% in both Passmark single-thread entries). The prime number result is particularly notable: the Intel chip's 107 score versus 66 for AMD represents a 38.3% advantage, the largest Intel win in the Passmark suite.

FAQ

Q: What is the memory bandwidth difference?

A: The AMD chip has dual-channel memory with 89.6 GB/s bandwidth. The Intel chip has single-channel memory with 59.7 GB/s. That is a 50% bandwidth advantage for the AMD part.

Q: Why does the AMD chip have so many more threads?

A: The AMD Ryzen 5 PRO 8540U has 12 threads from 6 cores, meaning simultaneous multithreading is active. The Intel Core 7 350 has 6 threads from 6 cores, so no multithreading. This directly contributes to the AMD chip's large multicore lead.

Q: Which processor has a lower TDP?

A: The Intel Core 7 350 is rated at 15 W, while the AMD Ryzen 5 PRO 8540U is rated at 28 W. The Intel chip draws less power, which may suit thinner laptops, but the AMD chip delivers substantially higher multi-threaded scores.

Where Each One Wins

The AMD Ryzen 5 PRO 8540U wins in all CPU throughput tests that scale with thread count and memory bandwidth. It takes 11 of 17 head-to-head tests. The wins include Cinebench R15, R20, and R23 multicore; R20 and R23 singlecore; data compression; data encryption; extended instructions; integer math; multithread; and random string sorting. This makes it the choice for video rendering, software compilation, data compression pipelines, encryption workloads, and any parallel integer-heavy processing. The 12 threads and dual-channel 89.6 GB/s memory give it a structural advantage in these tasks. The average benchmark score of 23709 versus 17779 for the Intel part reinforces this: the AMD chip is roughly 33% higher on average.

The Intel Core 7 350 wins 6 tests: Cinebench R15 singlecore, Passmark floating point math, Passmark physics, Passmark prime number finding, and both Passmark single-thread entries. The floating point math win (42809 versus 34865) suggests the Intel core design executes FP math more efficiently per clock. The physics score (1173 versus 983) points to better performance in certain simulation or constraint workloads. The prime number finding result (107 versus 66) indicates strong integer division or modular arithmetic throughput. For users running scientific floating point simulations, physics engines, or single-threaded legacy applications, the Intel chip holds an edge. The lower 15 W TDP also makes it suitable for passively cooled designs or battery-sensitive usage where maximum sustained multi-core load is not the priority.

The specification differences reinforce this split. The AMD chip has a 4.90 GHz boost clock versus 4.80 GHz for Intel, and a 3.20 GHz base clock versus 1.50 GHz. The AMD chip also has more PCIe lanes (14 versus 6) and dual-channel memory. The Intel chip has a newer process node (3 nm versus 4 nm) and a larger per-core L2 cache (2.5 MB versus 1 MB), which explains its single-thread and FP math wins. The AMD chip has a larger shared L3 (16 MB versus 6 MB), which helps in multi-threaded data-sharing workloads.

In practical terms, the data shows the AMD Ryzen 5 PRO 8540U as the higher-performance part for productive, parallel workloads, while the Intel Core 7 350 offers better efficiency per watt and wins in specific math-heavy or single-threaded scenarios. Neither chip has an unlocked multiplier, and both are mobile parts. The launch MSRP for the Intel Core 7 350 is $469. The AMD part has no launch MSRP listed in the database.
