AMD Ryzen 5 40 vs Intel Core 7 350 Comparison

The Verdict

The benchmark data is unambiguous: the Intel Core 7 350 wins every single recorded head-to-head test against the AMD Ryzen 5 40. Across 15 comparisons, Intel takes 15 wins, with zero victories for the AMD chip. The average benchmark score reflects this gap: the Intel Core 7 350 posts 17,779 versus 15,882 for the Ryzen 5 40, a difference of roughly 12%. The Intel part also sits slightly higher in the overall CPU percentile ranking, at 71 compared to 70 for the AMD processor.

The Intel Core 7 350 is the choice for anyone prioritizing raw compute throughput, whether in single-threaded responsiveness or heavily threaded workloads. Its advantages range from modest to overwhelming depending on the workload. The AMD Ryzen 5 40 remains a functional mobile processor, and its nearest rival cluster includes server-class EPYC parts with similar average scores, but it cannot match the Intel chip in any measured category. The data does not support recommending the AMD part for performance-driven scenarios. For buyers who need maximum compute capability in a 15 W mobile envelope, the Intel Core 7 350 is the clear pick from these two.

Architecture Differences

The two processors represent fundamentally different design philosophies and manufacturing approaches. The AMD Ryzen 5 40 uses the Zen 2 architecture under the Mendocino codename, built on a 6 nm process at TSMC. The Intel Core 7 350 uses the Wildcat Lake codename and is fabricated on Intel's 3 nm process. This node advantage likely contributes to the Intel part's performance lead, though the architectural differences run deeper.

Core counts differ significantly. The AMD chip offers 4 cores and 8 threads, using simultaneous multithreading to reach that thread count. The Intel chip provides 6 physical cores and 6 threads, with no hyperthreading support. Despite having fewer threads, the Intel processor wins all multithreaded benchmarks, indicating that its per-core performance advantage more than compensates for the two-core deficit in threaded work.

Cache hierarchies are notably different. The AMD Ryzen 5 40 allocates 64 KB of L1 cache per core, 512 KB of L2 per core, and 4 MB of shared L3 cache. The Intel Core 7 350 uses 192 KB of L1 per core, 2.5 MB of L2 per core, and 6 MB of shared L3. The Intel chip's larger per-core caches and bigger L3 pool give it a structural advantage in data-heavy workloads.

Memory support diverges as well. The AMD part supports LPDDR5 memory over a dual-channel bus, delivering 88.0 GB/s of bandwidth. The Intel part supports both DDR5 and LPDDR5X, but only over a single-channel bus, yielding 59.7 GB/s of bandwidth. This is a notable trade-off: the AMD chip offers substantially more memory bandwidth, yet it still loses memory-sensitive benchmarks to the Intel part, which suggests the Intel architecture uses its available bandwidth more efficiently.

Connectivity also differs. The AMD Ryzen 5 40 provides PCIe Gen 3 with 4 CPU lanes, while the Intel Core 7 350 offers PCIe Gen 4 with 6 CPU lanes. Integrated graphics are distinct: the AMD chip uses a Radeon 610M GPU, while the Intel chip employs Intel Xe3 Graphics with 2 Xe cores. Neither ECC memory nor an unlocked multiplier is available on either processor.

Head-to-Head Benchmarks

The Intel Core 7 350 dominates the Cinebench suite. In Cinebench R23 multi-core, Intel scores 8,030 against AMD's 4,841, a 39.7% advantage. Single-core R23 shows an even larger gap: 2,046 versus 1,150, a 43.8% lead. Cinebench R15 results follow the same pattern, with Intel ahead 1,220 to 790 in multi-core (35.2%) and 292 to 165.5 in single-core (43.3%). These results indicate that the Intel core design is significantly stronger on a per-thread basis, and that advantage carries through to multi-core workloads despite the thread count difference.

PassMark integer math is the closest contest. Intel scores 33,734 versus AMD's 31,598, a modest 6.3% edge. Data compression is similarly tight: Intel at 143,123 versus AMD at 141,533, just 1.1% apart. Random string sorting favors Intel by 12.3%, with scores of 17,238 and 15,124. These smaller margins suggest that the AMD chip remains competitive in certain integer and memory-access patterns, even though it loses overall.

The largest gaps appear in specialized workloads. PassMark find prime numbers shows Intel at 107 versus AMD at 20, an 81.3% deficit for the AMD part. Floating point math favors Intel by 64.5%, with scores of 42,809 and 15,194. Physics simulation gives Intel a 63.2% edge, 1,173 to 432. Extended instructions show a 46.6% gap, with Intel at 12,045 and AMD at 6,437.

Data encryption also favors Intel heavily: 10,933 versus 6,646, a 39.2% gap. PassMark multi-thread gives Intel 15,170 against AMD's 9,341, a 38.4% lead. Single-thread PassMark shows Intel at 4,100 versus AMD at 2,477, a 39.6% difference. Across every recorded benchmark, the Intel Core 7 350 delivers the higher score, with the closest margins in integer math and data compression.
