AMD Ryzen 9 9955HX vs Intel Core 7 350 Comparison

The Verdict

The data in the database draws a clear line between these two mobile processors. The AMD Ryzen 9 9955HX wins all 15 head-to-head benchmark comparisons against the Intel Core 7 350, with no recorded wins for the Intel part. The AMD chip sits at the 96th percentile of all CPUs, while the Intel Core 7 350 lands at the 71st percentile. This is not a close contest; it is a decisive performance separation.

The Ryzen 9 9955HX is the choice for workloads that demand heavy multi-threading, large data throughput, and sustained compute. Its average benchmark score of 91,199 dwarfs the Intel part's average of 17,779. The nearest rivals to the AMD chip are the Intel Xeon 654 (0.5% behind), AMD Ryzen AI Max+ 392 (0.7% behind), Intel Core Ultra 7 270K Plus (2.8% ahead), and Intel Xeon 6520P (2.8% ahead). The Intel Core 7 350, by contrast, sits alongside the Intel Core 5 221TE (0.5% behind), AMD EPYC 9374F (0.5% ahead), AMD Ryzen 5 3600XT (0.6% behind), and Intel Core 5 120U (0.7% behind). The AMD part competes in a much higher performance class.

The Intel Core 7 350 is a different kind of mobile chip. It uses a 3 nm process, has a 15 W TDP, and is built for efficiency-oriented systems. The database shows it is not competitive with the Ryzen 9 9955HX in any measured metric, but its position in the 71st percentile and its modest power envelope indicate it targets a different segment of the laptop market. The launch MSRP for the Intel part is $469, though the AMD chip has no recorded launch MSRP in the database. Users who need maximum compute should choose the AMD part; users who prioritize low power consumption in a compact design would consider the Intel part, but only if the performance gap is acceptable.

Where Each One Wins

The AMD Ryzen 9 9955HX wins every benchmark in the head-to-head dataset, so the use-case split is defined by the magnitude of its advantages rather than by any Intel victories. The largest deltas appear in integer math and data compression. The AMD chip scores 212,598 in PassMark integer math versus 33,734 for Intel, a 530.2% advantage. Data compression shows a 411.4% delta (731,998 versus 143,123). These are workloads where core count and thread count dominate, and the AMD part has 16 cores and 32 threads against the Intel part's 6 cores and 6 threads.

Multithreaded rendering also heavily favors AMD. The Cinebench R23 multicore score is 37,159 for the Ryzen 9 9955HX versus 8,030 for the Core 7 350, a 362.8% gap. The R15 multicore test shows a 384% delta (5,905 versus 1,220). Extended instruction workloads, which exercise SIMD and cryptographic instruction sets, favor AMD by 381.1% (57,946 versus 12,045). Floating point math shows a 219.3% delta (136,682 versus 42,809), and data encryption a 241.4% delta (37,330 versus 10,933).

The smallest wins for AMD are in single-threaded tests, where the architectural gap narrows. Cinebench R23 single-core shows 2,174 versus 2,046, a 6.3% delta. PassMark single-thread shows 4,393 versus 4,100, a 7.1% delta. Cinebench R15 single-core shows 336 versus 292, a 15.1% delta. Even in these cases, AMD leads, but the margins are much smaller than in multi-threaded workloads.

The Intel Core 7 350 has no category where it wins outright. Its closest performance relative to AMD is in single-threaded benchmarks, where it trails by roughly 6% to 15%. The data suggests that for lightly threaded tasks like basic office work or web browsing, the Intel chip is not far behind. For any parallel workload, the AMD chip is multiple times faster.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 9955HX belongs to the 9000 series and uses the Zen 5 architecture under the Fire Range codename. It is manufactured by TSMC on a 4 nm process and contains 16,630 million transistors across a dual-chiplet design with a die size of 2x 70.6 mm². The Intel Core 7 350 uses the Wildcat Lake codename and is manufactured by Intel on a 3 nm process. The database does not list transistor count or die size for the Intel part.

Core and thread counts diverge sharply. The AMD chip has 16 cores and 32 threads, with a base clock of 2.50 GHz and a boost clock of 5.40 GHz. The Intel chip has 6 cores and 6 threads, with a base clock of 1.50 GHz and a boost clock of 4.80 GHz. The Intel part has no hyper-threading, which explains why thread count equals core count. The AMD part's 32 threads give it a massive advantage in parallel workloads.

Cache hierarchies also differ. The AMD chip has 80 KB of L1 cache per core, 1 MB of L2 per core, and 64 MB of shared L3 cache. The Intel chip has 192 KB of L1 per core, 2.5 MB of L2 per core, and only 6 MB of shared L3 cache. The AMD part's 64 MB L3 is more than ten times larger than the Intel part's 6 MB, which helps with data-heavy workloads and repeated access patterns.

Memory support and I/O differ as well. The AMD chip supports DDR5 with a dual-channel memory bus and a memory bandwidth of 89.6 GB/s. It also supports ECC memory. The Intel chip supports DDR5 and LPDDR5X but uses a single-channel memory bus with a bandwidth of 59.7 GB/s, and it does not support ECC. PCIe connectivity favors AMD: the Ryzen 9 9955HX offers Gen 5 with 28 lanes, while the Intel Core 7 350 offers Gen 4 with 6 lanes.

The TDP ratings reflect their different positioning. The AMD chip has a 55 W TDP, while the Intel chip has a 15 W TDP. The Intel part is locked (multiplier unlocked: false), while the AMD part has an unlocked multiplier. Integrated graphics also differ: the AMD chip uses a Radeon 610M, while the Intel chip uses Intel Xe3 Graphics with 2 Xe cores. The release dates in the database show the AMD chip from January 2025 and the Intel chip from April 2026, though no further interpretation of that timeline is needed here.

Head-to-Head Benchmarks

The largest single delta in the entire dataset is PassMark integer math, where the AMD Ryzen 9 9955HX scores 212,598 against the Intel Core 7 350's 33,734. That is a 530.2% advantage, the biggest margin recorded in any test. This metric measures arithmetic operations on integer data, and the gap reflects the AMD chip's 16 cores, 32 threads, and larger cache.

Data compression follows closely. The AMD chip scores 731,998 versus 143,123, a 411.4% delta. Compression workloads are highly parallel and memory-bandwidth sensitive, and the AMD chip's 89.6 GB/s bandwidth and 64 MB L3 cache provide a clear structural advantage over the Intel chip's 59.7 GB/s and 6 MB L3.

Cinebench R23 multicore shows a 362.8% delta (37,159 versus 8,030). This is a standard rendering benchmark that scales with core count, and the AMD chip's 32 threads overwhelm the Intel chip's 6. Cinebench R15 multicore shows a similar pattern: 5,905 versus 1,220, a 384% delta. Extended instructions show 57,946 versus 12,045, a 381.1% delta, indicating the AMD chip handles SIMD and cryptographic instruction sets far more effectively.

Random string sorting shows 77,890 versus 17,238, a 351.9% delta. This test stresses memory allocation and pointer chasing, where the AMD chip's larger L3 and dual-channel memory bus matter. PassMark multithread shows 56,171 versus 15,170, a 270.3% delta, confirming the multi-threaded dominance across a broad mix of tasks.

Data encryption shows 37,330 versus 10,933, a 241.4% delta. Floating point math shows 136,682 versus 42,809, a 219.3% delta. Find prime numbers shows 287 versus 107, a 168.2% delta. PassMark physics shows 2,720 versus 1,173, a 131.9% delta. Each of these tests follows the same pattern: the AMD chip is between 1.3 and 2.4 times faster, with the advantage scaling roughly with the parallelism of the workload.

The narrowest margins are in single-threaded tests. PassMark single-thread shows 4,393 versus 4,100, a 7.1% delta. Cinebench R23 single-core shows 2,174 versus 2,046, a 6.3% delta. Cinebench R15 single-core shows 336 versus 292, a 15.1% delta. These results indicate that the AMD chip's Zen 5 architecture has a modest per-core performance lead over the Intel Wildcat Lake design, but the overwhelming differences come from core count, thread count, and cache capacity.

The Intel Core 7 350 does have a recorded Cinebench R20 result (5,373 multicore, 758 single-core) and a PassMark physics score of 1,173, but there is no corresponding AMD R20 score in the head-to-head dataset, so no direct comparison is possible for that specific test. The overall picture from the recorded data is unambiguous: the AMD Ryzen 9 9955HX dominates every comparable metric, and the Intel Core 7 350 occupies a lower performance tier with a significantly lower power envelope.
