AMD Ryzen AI 7 450G vs Intel Core i5-14400 Comparison

The database compares the AMD Ryzen AI 7 450G and the Intel Core i5-14400 as two 65 W desktop CPUs with 16 threads each. The AMD part uses 8 cores, a 2.00 GHz base clock, and a 5.10 GHz boost clock, while the Intel part uses 10 cores, a 2.50 GHz base clock, and a 4.70 GHz boost clock. In the recorded head-to-head PassMark set, the AMD part wins every test, and its overall database percentile is 93 versus 82 for Intel.

The Verdict

The verdict from the recorded data is clear: the AMD Ryzen AI 7 450G dominates the shared benchmark suite. It wins all 11 head-to-head PassMark comparisons, with margins ranging from 3.2% in physics to 42.4% in extended instructions. The Intel Core i5-14400 wins none of those tests. AMD also carries the higher average benchmark score, 63331 versus 32115, and the higher percentile ranking, 93 versus 82.

That average score gap should be read with care because the two entries contain different benchmark sets. The AMD entry lists PassMark results only, while the Intel entry also lists Cinebench and Geekbench results. In the tests common to both processors, AMD is consistently ahead. The largest head-to-head margin is 42.4% in extended instructions; the smallest is 3.2% in physics. Single-thread performance favors AMD by 15.2%, multithread performance favors AMD by 21.3%, and data compression favors AMD by 27.9%.

The Intel part still offers a different platform profile. It has 10 cores instead of 8, a 20 MB shared L3 cache instead of 8 MB, DDR4 and DDR5 memory support, PCIe Gen 5 with 16 CPU lanes, and an Intel Socket 1700 footprint. For workloads that resemble the measured PassMark suite, the data points to the AMD part. For builds that require the Intel platform features, the i5-14400 is the alternative.

Architecture Differences

The two CPUs differ at the process, core, cache, memory, and platform levels. AMD lists a TSMC 4 nm process and a 195 mm² die. Intel lists its own 10 nm process and a 215 mm² die. AMD's codename is Gorgon Point, with generation Ryzen AI 400 (Zen 5 / Zen 5c). Intel's codename is Raptor Lake-R, with generation Core i5 (Raptor Lake Refresh).

Core counts differ, but thread counts do not. AMD uses 8 cores and 16 threads. Intel uses 10 cores and 16 threads. Base and boost clocks move in opposite directions: Intel has the higher base clock at 2.50 GHz versus 2.00 GHz, while AMD has the higher boost clock at 5.10 GHz versus 4.70 GHz.

Cache layouts also differ. Both provide 80 KB of L1 per core, but AMD gives 1 MB of L2 per core and an 8 MB L3 cache, while Intel gives 1.25 MB of L2 per core and a 20 MB shared L3 cache. Memory support differs as well. AMD accepts DDR5 and LPDDR5X with a recorded 89.6 GB/s memory bandwidth. Intel accepts DDR4 and DDR5, with no bandwidth figure recorded. Both use a dual-channel memory bus and support ECC.

Platform features diverge further. AMD uses AMD Socket AM5 and PCIe Gen 4 with 12 CPU-only lanes. Intel uses Intel Socket 1700 and PCIe Gen 5 with 16 CPU-only lanes. The integrated graphics are the Radeon 860M on the AMD side and the UHD Graphics 730 on the Intel side. AMD has an unlocked multiplier; Intel does not. AMD's release date is 2026-02-28, while Intel's is 2024-01-07.

FAQ

Q: Which CPU has the higher PassMark single-thread score?

A: The AMD Ryzen AI 7 450G scores 4309, which is 15.2% higher than the Intel Core i5-14400's 3741.

Q: Does the Intel Core i5-14400 have more cores?

A: Yes, 10 cores versus 8, and both have 16 threads. Despite the core deficit, AMD wins the PassMark multithread test 30422 to 25080, a 21.3% margin.

Q: How do the cache sizes differ?

A: AMD provides 1 MB of L2 per core and 8 MB of L3. Intel provides 1.25 MB of L2 per core and 20 MB of shared L3. Both have 80 KB of L1 per core.

Q: Which memory types does each CPU support?

A: AMD supports DDR5 and LPDDR5X. Intel supports DDR4 and DDR5. Both are dual-channel and ECC-capable.

Q: What do the overall database scores show?

A: AMD has an average benchmark score of 63331 and a 93rd percentile ranking. Intel has an average benchmark score of 32115 and an 82nd percentile ranking. The benchmark lists differ, so the head-to-head PassMark results are the more direct comparison.

Q: Are there Cinebench or Geekbench results for both CPUs?

A: The Intel entry includes Cinebench R15, R20, R23 and Geekbench scores, but the AMD entry does not. The head-to-head set is limited to PassMark tests.

Head-to-Head Benchmarks

The recorded head-to-head set contains 11 PassMark tests. The AMD Ryzen AI 7 450G wins all 11, and the Intel Core i5-14400 wins none. The largest AMD margin is 42.4% in extended instructions: 28223 versus 19816. Random string sorting follows at 31.9%, with 42663 against 32346. Data compression is next at 27.9%, 402831 versus 314995.

Integer math shows a 21.6% margin, 99732 versus 82017. Multithread performance is 21.3% ahead, 30422 versus 25080. Single-thread performance is 15.2% ahead, 4309 versus 3741. Data encryption is 13.2% ahead, 18937 versus 16731.

The remaining tests are closer. Find prime numbers is 8.8% ahead, 87 versus 80. Floating point math is 3.5% ahead, 63683 versus 61549. Physics is 3.2% ahead, 1440 versus 1396. No Intel win appears anywhere in the head-to-head result set.

The Intel part has additional recorded Cinebench and Geekbench scores, but the AMD part does not, so those cannot be used for a same-test comparison. The PassMark head-to-head results are the only directly comparable measurements, and they consistently favor the AMD Ryzen AI 7 450G.
