AMD Ryzen 9 9955HX3D vs Intel Core 7 350 Comparison

The AMD Ryzen 9 9955HX3D and Intel Core 7 350 are both active mobile processors, but the database places them in different classes. In the 15 shared head-to-head benchmarks, the AMD part wins all 15 and the Intel part wins none. The AMD part averages 97453 across all recorded tests and sits in the 96th percentile of all CPUs, while the Intel part averages 17779 and sits in the 71st percentile. These reference points frame the entire comparison.

Head-to-Head Benchmarks

The AMD Ryzen 9 9955HX3D leads by the largest margins in the compute-heavy tests. The largest margin is PassMark integer math: 222503 versus 33734, a delta of 559.6%. Data compression follows at 449% (785811 versus 143123), extended instructions at 421.5% (62813 versus 12045), Cinebench R15 multi-core at 395.3% (6042.5 versus 1220), find prime numbers at 390.7% (525 versus 107), random string sorting at 384.4% (83497 versus 17238), Cinebench R23 multi-core at 375.2% (38161.5 versus 8030), PassMark multithread at 313.1% (62674 versus 15170), physics at 299.6% (4687 versus 1173), data encryption at 260.8% (39446 versus 10933), and floating-point math at 236.7% (144122 versus 42809).

The remaining margins are all single-core tests. Cinebench R23 single-core is the closest: 2159.5 versus 2046, a delta of 5.5%. PassMark single-thread entries share identical scores, 4511 versus 4100, a delta of 10%. Cinebench R15 single-core is 332 versus 292, a delta of 13.7%. Even where the Intel part is relatively strongest, the AMD part still leads.

Where Each One Wins

On benchmark wins, the split is lopsided: the AMD part holds all 15 wins, and the Intel part holds none. The AMD part wins every Cinebench R15 and R23 test, plus every PassMark workload in the shared set. That makes the AMD part the data-backed choice for compute-heavy use cases such as multi-threaded rendering, integer math, data compression, encryption, and physics simulation, all of which appear in the recorded scores.

The Intel part does not register a benchmark win, but its recorded platform traits point to a different use case. It has a TDP of 15, supports DDR5 and LPDDR5X, and uses a single-channel memory bus with 59.7 GB/s of bandwidth. The AMD part has a TDP of 55, supports DDR5, and uses a dual-channel bus with 89.6 GB/s. The Intel part also uses PCIe Gen 4 with 6 CPU lanes, while the AMD part uses PCIe Gen 5 with 28 CPU lanes. In the database, the Intel part is not a performance alternative to the AMD part; it is a lower-power, lower-bandwidth mobile design.

Architecture Differences

The chips come from different foundries and process nodes. The AMD uses a 4 nm TSMC process, Zen 5 architecture, and the Fire Range codename. The Intel uses a 3 nm Intel process and the Wildcat Lake codename; its architecture field is not listed in the database. The AMD generation is listed as Ryzen 9 (Zen 5 (Fire Range)), while the Intel generation is listed as Core 5 (Wildcat Lake).

The core configurations diverge sharply. The AMD has 16 cores and 32 threads, with a base clock of 2.50 and a boost clock of 5.40. The Intel has 6 cores and 6 threads, with a base clock of 1.50 and a boost clock of 4.80. The AMD is an unlocked part; the Intel is locked. The AMD uses AMD Socket FL1, and the Intel uses Intel BGA 1516.

Cache hierarchies are also different. The AMD has 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3. The Intel has 192 KB of L1 per core, 2.5 MB of L2 per core, and 6 MB of shared L3. The AMD's L3 is far larger, while the Intel has more L1 and L2 per core.

The platform features differ as well. The AMD supports DDR5 over a dual-channel bus with 89.6 GB/s bandwidth and ECC memory. The Intel supports DDR5 and LPDDR5X over a single-channel bus with 59.7 GB/s bandwidth and no ECC. The AMD provides PCIe Gen 5 with 28 CPU lanes; the Intel provides PCIe Gen 4 with 6 CPU lanes. Integrated graphics differ: the AMD uses Radeon 610M, and the Intel uses Intel Xe3 Graphics (2 Xe). The AMD die is listed as 2x 70.6 mm² with 16,630 million transistors, while the Intel record does not list die size or transistor count. The release dates are 2025-01-05 for the AMD and 2026-04-15 for the Intel.

The Verdict

The head-to-head data is unambiguous. The AMD Ryzen 9 9955HX3D wins every shared benchmark, and the Intel Core 7 350 wins none. The average benchmark scores place the AMD at 97453 and the Intel at 17779, with CPU percentiles of 96 and 71 respectively. The nearest-rival comparisons reinforce the separation: the AMD's average score is 1.1% below the AMD Ryzen Threadripper PRO 5965WX and 1.4% above the AMD Ryzen 9 PRO 9945, while the Intel's average score is 0.5% above the AMD EPYC 9374F and 0.7% below the Intel Core 5 120U.

For workloads captured by Cinebench R15, Cinebench R23, and the PassMark suite, the AMD part is the only part with a winning record in the database. For system designs that must fit a 15 TDP envelope, use single-channel memory, and include LPDDR5X support, the Intel part matches those constraints. The data does not show a middle ground: the AMD part dominates the performance tests, and the Intel part occupies a lower-power platform niche.
