AMD Ryzen 9 9900X vs Intel Core 7 350 Comparison

The AMD Ryzen 9 9900X and Intel Core 7 350 occupy different corners of the processor market, and the benchmark data reflects that separation clearly. The recorded measurements show a consistent and substantial performance advantage for the AMD part across every single shared test. The Intel Core 7 350, a mobile-focused chip with a 15 W TDP, is not competing on raw throughput; it is built for efficiency in a compact package. The data shows the Ryzen 9 9900X delivering anywhere from 10.1% to 436.7% higher scores depending on the workload, with the largest gaps appearing in heavily parallel tasks.

Head-to-Head Benchmarks

The most dramatic difference appears in PassMark integer math, where the Ryzen 9 9900X scores 181056 against the Core 7 350's 33734, a delta of 436.7%. This is the largest margin in the entire comparison and highlights the massive gap in multi-threaded integer throughput. Data compression shows a similar story: 683579 versus 143123, a 377.6% advantage for the AMD chip. Extended instructions follow at 358.6% ahead (55243 versus 12045), and random string sorting shows a 317.8% lead (72013 versus 17238). Prime number finding is 307.5% faster (436 versus 107).

Cinebench results reinforce the pattern. In Cinebench R23 multi-core, the Ryzen 9 9900X scores 32172 versus 8030, a 300.6% advantage. Cinebench R15 multi-core shows a 310.5% lead (5008 versus 1220). PassMark multi-thread delivers 54643 versus 15170, a 260.2% gap. Floating point math shows 120083 versus 42809, an 180.5% lead. Physics tests show 3381 versus 1173, a 188.2% margin. Data encryption results are 205.7% higher on the AMD side (33421 versus 10933).

Single-thread performance is much closer, which is expected given that both chips use modern architectures. PassMark single-thread shows 4672 versus 4100, a 14% advantage for the Ryzen 9 9900X. Cinebench R23 single-core shows 2253 versus 2046, a 10.1% lead. Cinebench R15 single-core shows 353 versus 292, a 20.9% margin. These smaller deltas indicate that the architectural efficiency of the two designs is comparable at low thread counts; the massive overall difference comes from the Ryzen 9's 12 cores and 24 threads versus the Core 7 350's 6 cores and 6 threads.

The Ryzen 9 9900X wins all 15 head-to-head tests. The Intel Core 7 350 does not record a single victory. The average benchmark score for the AMD part is 57498, placing it in the 92nd percentile of all CPUs. The Intel part averages 17779, which puts it in the 71st percentile. For context, the Ryzen 9 9900X sits near the AMD EPYC 9015 (57555, 0.1% behind) and the Intel Core i9-14900 (58115, 1.1% behind). The Core 7 350's nearest rivals include the AMD Ryzen 5 3600XT (17891, 0.6% ahead) and the Intel Core 5 120U (17898, 0.7% ahead), showing it slots into a much lower performance tier.

The Verdict

The data directs a clear split. Anyone building a desktop system for demanding multi-threaded work, such as rendering, compilation, or heavy data processing, should choose the AMD Ryzen 9 9900X. Its 12-core, 24-thread configuration delivers between 2.6x and 5.4x the performance of the Intel part in parallel workloads, and it maintains a meaningful lead in single-thread tests as well. The 92nd percentile ranking places it among the top desktop processors in the database.

The Intel Core 7 350 serves a different purpose. It is a mobile chip with a 15 W TDP, 6 cores, and 6 threads, designed for compact, power-constrained systems. Its 71st percentile ranking is respectable for its class, but it cannot match the desktop part in sustained throughput. The recorded data shows no scenario where the Intel chip outperforms the AMD chip. The choice is not about which is better in absolute terms; it is about which fits the intended system. For a desktop tower, the Ryzen 9 9900X is the obvious pick. For a thin-and-light laptop, the Core 7 350 is the only viable option in this comparison, given its socket and power profile.

Specification Differences

The two processors differ in nearly every fundamental specification. The AMD Ryzen 9 9900X uses 12 cores and 24 threads, while the Intel Core 7 350 uses 6 cores and 6 threads. The AMD part has a base clock of 4.40 GHz and a boost clock of 5.60 GHz; the Intel part runs at 1.50 GHz base and 4.80 GHz boost. TDP is a major divider: 120 W for the AMD chip versus 15 W for the Intel chip. The Ryzen 9 9900X uses AMD Socket AM5, while the Core 7 350 uses Intel BGA 1516, a soldered mobile socket. Memory support differs as well: the AMD chip uses dual-channel DDR5 with 89.6 GB/s bandwidth and ECC support, while the Intel chip uses single-channel DDR5 and LPDDR5X with 59.7 GB/s and no ECC. PCIe lanes also differ: the AMD part provides Gen 5 with 24 lanes, the Intel part provides Gen 4 with 6 lanes. The AMD chip has an unlocked multiplier; the Intel chip does not. The integrated graphics differ, with the AMD part using Radeon Graphics and the Intel part using Intel Xe3 Graphics (2 Xe).

Architecture Differences

The architectural split is fundamental. The AMD Ryzen 9 9900X is built on the Zen 5 architecture with the Granite Ridge codename, produced on TSMC's 4 nm process. It uses 16,630 million transistors across a die size of 2x 70.6 mm². Its cache layout includes 80 KB of L1 per core, 1 MB of L2 per core, and a 64 MB L3 cache. The Intel Core 7 350 uses the Wildcat Lake codename, produced on Intel's own 3 nm process. It has a different cache structure: 192 KB of L1 per core, 2.5 MB of L2 per core, and 6 MB of shared L3 cache. The transistor count and die size for the Intel part are not recorded in the database. The AMD chip is a dual-die design with a large shared L3 pool, which helps its multi-threaded performance. The Intel chip is a single, efficiency-focused design with a much smaller L3 cache, consistent with its low-power mobile role. The AMD part's 4 nm TSMC process and 120 W TDP allow for high clock speeds and sustained throughput. The Intel part's 3 nm Intel process and 15 W TDP prioritize energy efficiency over peak performance.

Where Each One Wins

The AMD Ryzen 9 9900X wins in every measured category. It dominates in multi-threaded rendering, as shown by the Cinebench R23 multi-core score of 32172 versus 8030. It leads in data compression (683579 versus 143123) and encryption (33421 versus 10933), making it the better choice for file archiving and secure data handling. Integer math (181056 versus 33734) and floating-point math (120083 versus 42809) both favor the AMD part decisively, which matters for scientific computing and financial modeling. Physics simulation (3381 versus 1173) and random string sorting (72013 versus 17238) also go to the AMD chip. Even in single-thread tests, the Ryzen 9 9900X holds a 10% to 21% lead, meaning it is also the better choice for lightly threaded applications like older games or single-threaded productivity tools.

The Intel Core 7 350 does not win any benchmark in this comparison. Its utility comes from its form factor and power envelope, not its performance class. The 15 W TDP and BGA 1516 socket make it suitable for compact laptops where cooling and battery life take priority over raw speed. Its 6 MB L3 cache and 6 lanes of PCIe Gen 4 are aligned with that use case. The data shows that for any workload measured in this database, the Ryzen 9 9900X is the superior processor. The Core 7 350's only advantage is that it exists in a segment where the Ryzen 9 9900X cannot go: a low-power mobile socket. For desktop users, the choice is unambiguous. For mobile users, the Core 7 350 is the only one of the two that fits the hardware requirements.
