AMD Ryzen 5 8400F vs Intel Core 7 350 Comparison

Where Each One Wins

The AMD Ryzen 5 8400F dominates this head-to-head with 14 benchmark wins out of 17 recorded comparisons. Its decisive advantage lies in multi-threaded work, where the combination of 12 threads versus the Intel Core 7 350's 6 threads produces massive gaps. The Cinebench R23 multi-core result is the standout: 20851 versus 8030, a 159.7% margin. That is not a small edge; it is more than double the score. The PassMark integer math test shows a similar pattern at 74021 versus 33734, a 119.4% difference. Data compression also favors AMD strongly at 288158 versus 143123, a 101.3% lead. Random string sorting follows at 34604 versus 17238, a 100.7% gap. These are workloads that scale with thread count, and the data confirms the Ryzen 5 8400F crushes them.

The Intel Core 7 350 wins only three benchmarks, but they matter for specific use cases. PassMark single-thread scores go to Intel at 4100 versus 3685, a 10.1% advantage. This is a meaningful lead for lightly threaded applications that depend on one core's peak performance. The other Intel win is PassMark find prime numbers at 107 versus 89, a 16.8% margin. That test rewards a different kind of integer efficiency, and Intel's architecture handles it better despite the thread deficit. Those are the only two tests where Intel comes out ahead, so the pattern is clear: Intel wins where clock speed and single-core efficiency dominate, AMD wins everywhere else.

The average benchmark score reinforces the split. The Ryzen 5 8400F sits at 25005, which places it in the 77th percentile of all CPUs in the database. The Intel Core 7 350 averages 17779, placing it in the 71st percentile. The raw average difference is 7226 points, roughly 40.6% higher for AMD. The nearest rivals for each chip confirm the positioning. The Ryzen 5 8400F sits within 0.4% of the AMD Ryzen 5 7500F, the Intel Core i7-11850H, the Intel Core i7-13620H, and the AMD EPYC 9474F. The Intel Core 7 350 sits within 0.7% of the Intel Core 5 221TE, the AMD EPYC 9374F, the AMD Ryzen 5 3600XT, and the Intel Core 5 120U. These are different performance neighborhoods entirely.

The Verdict

The data points to a simple conclusion for most users: the AMD Ryzen 5 8400F is the stronger processor for multi-threaded workloads. The Cinebench R23 multi-core score of 20851 is 159.7% ahead of the Intel's 8030. The PassMark multi-thread score of 24389 is 60.8% ahead of the Intel's 15170. Anyone running rendering, compilation, data compression, or encryption workloads should pick the AMD part. The encryption test shows a 52.3% lead at 16646 versus 10933. The extended instructions test shows an 84.1% lead at 22175 versus 12045. These are not marginal differences; they are generational gaps in throughput.

The Intel Core 7 350 has one clear niche: single-thread performance. The PassMark single-thread score of 4100 beats the AMD's 3685 by 10.1%. That is the only category where Intel holds a decisive edge, aside from the prime number calculation. For users running applications that are strictly single-threaded and cannot use additional cores, the Intel chip will feel faster. But the Cinebench R15 single-core scores tell a different story: the AMD wins 296 to 292, just 1.4% apart. So the single-thread advantage is not consistent across all tests. The PassMark test shows Intel ahead by 10.1%, while Cinebench R15 shows AMD marginally ahead. The Cinebench R23 single-core result also goes to AMD at 2943 versus 2046, a 43.8% lead. That inconsistency matters: the Intel single-thread win is real in PassMark, but not universal.

The Intel Core 7 350 is a mobile part with a 15 watt TDP, while the AMD Ryzen 5 8400F is a desktop part with a 65 watt TDP. The data reflects that power envelope difference. The Intel chip's launch MSRP is $469. The AMD chip's launch MSRP is $170. The performance data does not justify that price gap for most workloads, but the form factor and power characteristics are different categories entirely.

Head-to-Head Benchmarks

The largest margin in the entire comparison is Cinebench R23 multi-core. The AMD Ryzen 5 8400F scores 20851, the Intel Core 7 350 scores 8030, and the delta is 159.7%. No other test comes close to that gap. The PassMark integer math test is next at 119.4% (74021 versus 33734). Data compression follows at 101.3% (288158 versus 143123). Random string sorting is at 100.7% (34604 versus 17238). These four tests all show the AMD chip delivering roughly double the throughput of the Intel chip.

The extended instructions test shows an 84.1% lead for AMD at 22175 versus 12045. The Cinebench R15 multi-core test shows a 72.2% lead at 2101 versus 1220. The Cinebench R20 multi-core test shows a 63% lead at 8757 versus 5373. The Cinebench R20 single-core test shows a 63.1% lead at 1236 versus 758, which is surprising because it is a single-thread test, yet the AMD chip wins by a wide margin. The PassMark multi-thread test shows a 60.8% lead at 24389 versus 15170. The data encryption test shows a 52.3% lead at 16646 versus 10933. The Cinebench R23 single-core test shows a 43.8% lead at 2943 versus 2046.

The smaller AMD wins are still meaningful. Floating point math goes to AMD at 46217 versus 42809, an 8% lead. Physics goes to AMD at 1332 versus 1173, a 13.6% lead. Cinebench R15 single-core goes to AMD at 296 versus 292, just 1.4% apart. These are closer contests, but AMD still takes them.

The Intel wins are concentrated in two tests. PassMark single-thread (and the duplicate singlethread entry) shows Intel at 4100 versus AMD at 3685, a 10.1% lead. PassMark find prime numbers shows Intel at 107 versus AMD at 89, a 16.8% lead. The prime number test is an interesting outlier because it is the only test where the Intel chip wins by a double-digit margin other than single-thread. It suggests the Intel architecture has a specific strength in integer-heavy scalar loops that the AMD architecture does not match.

A: The Intel Core 7 350 has a boost clock of 4.80 GHz. The AMD Ryzen 5 8400F has a boost clock of 4.70 GHz. The Intel chip is 0.10 GHz higher, but the base clocks differ far more: Intel at 1.50 GHz versus AMD at 4.20 GHz.

Architecture Differences

The AMD Ryzen 5 8400F uses the Zen 4 architecture under the Phoenix codename. It is built on a 4 nm process at TSMC, with 25,000 million transistors on a 178 mm² die. The Intel Core 7 350 uses the Wildcat Lake codename and is built on a 3 nm process at Intel. The transistor count and die size for the Intel part are not recorded in the database.

Cache layouts differ substantially. The AMD chip has 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3. The Intel chip has 192 KB of L1 per core, 2.5 MB of L2 per core, and 6 MB of shared L3. The Intel L1 and L2 caches are larger per core, but the shared L3 is less than half the size of the AMD's. This cache structure likely contributes to the Intel's PassMark single-thread advantage, but it does not overcome the thread count deficit in multi-threaded tests.

Memory architecture is another major split. The AMD Ryzen 5 8400F supports DDR5 with a dual-channel memory bus and a recorded bandwidth of 83.2 GB/s. The Intel Core 7 350 supports DDR5 and LPDDR5X, but uses a single-channel memory bus with a recorded bandwidth of 59.7 GB/s. The AMD chip delivers 39.4% more memory bandwidth, which feeds its advantage in data-heavy workloads like compression and encryption.

PCIe connectivity also differs. The AMD chip provides Gen 4 with 20 lanes (CPU only). The Intel chip provides Gen 4 with 6 lanes (CPU only). Neither chip has ECC memory support. Neither chip has a 3D V-Cache option recorded in the database.

The Intel Core 7 350 includes integrated graphics with Intel Xe3 Graphics (2 Xe cores). The AMD Ryzen 5 8400F has no integrated graphics at all. This makes the Intel chip a complete mobile package, while the AMD chip requires a discrete graphics card.
