Head-to-Head Benchmarks

The head-to-head data reveals where each processor builds its case. The Intel Core i5-14400 wins 7 of 11 tests, but the AMD Ryzen AI 5 440G wins the tests that matter most for single-thread responsiveness.

The largest Intel victory comes in floating point math. The Core i5-14400 scores 61549 against the Ryzen AI 5 440G's 45711, a 25.7% margin. Integer math follows a similar pattern: Intel scores 82017 versus 71251, a 13.1% lead. Data encryption also favors Intel, with 16731 against 13585, an 18.8% gap. These three tests alone establish the Intel part as the stronger choice for math-heavy and encryption-heavy workloads.

The Intel part also wins data compression at 314995 versus 292735, a 7.1% margin. The multithread test goes to Intel at 25080 versus 23487, a 6.4% lead. Physics simulation favors Intel at 1396 versus 1329, a 4.8% margin. Random string sorting rounds out the Intel wins at 32346 versus 31106, a 3.8% edge.

The AMD Ryzen AI 5 440G claims its biggest win in single-thread performance. The AMD part scores 4060 against Intel's 3741, an 8.5% margin, and the same result appears twice in the recorded data. Prime number finding goes to AMD at 90 versus 80, a 12.5% lead. Extended instructions favor AMD at 20648 versus 19816, a 4.2% margin.

The pattern is consistent: Intel wins the throughput tests by wide margins, while AMD wins the per-thread and specialized instruction tests. The AMD part's average benchmark score of 46187 versus Intel's 32115 suggests that the AMD processor's wins carry outsized weight in the overall ranking, even though Intel wins more individual tests.

Specification Differences

The core and thread counts differ substantially. The AMD Ryzen AI 5 440G uses 6 cores and 12 threads, while the Intel Core i5-14400 uses 10 cores and 16 threads. The Intel part's additional cores explain its throughput advantages in the benchmark data.

Clock speeds also differ. The AMD part has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The Intel part has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The AMD part boosts higher, which aligns with its single-thread win. The Intel part starts higher at base, which helps in sustained all-core workloads.

Memory support differs. The AMD Ryzen AI 5 440G supports DDR5 only, with dual-channel memory and a recorded bandwidth of 89.6 GB/s. The Intel Core i5-14400 supports both DDR4 and DDR5, also dual-channel, with no recorded bandwidth figure in the database. The AMD part's narrower memory support is offset by a specified bandwidth number.

PCIe connectivity differs significantly. The AMD part uses Gen 4 with 12 lanes from the CPU. The Intel part uses Gen 5 with 16 lanes from the CPU. Intel offers both a newer PCIe generation and more lanes, which matters for expansion and high-speed storage.

The integrated graphics differ. AMD uses the Radeon 840M, while Intel uses UHD Graphics 730. The socket and platform also differ: AMD uses Socket AM5, Intel uses Socket 1700.

The multiplier unlock status differs. The AMD Ryzen AI 5 440G has an unlocked multiplier, while the Intel Core i5-14400 does not.

Architecture Differences

The two processors come from different design generations and manufacturing processes. The AMD Ryzen AI 5 440G uses the Gorgon Point codename and belongs to the Ryzen AI 400 generation, built on a mix of Zen 5 and Zen 5c cores. The Intel Core i5-14400 uses the Raptor Lake-R codename and belongs to the Core i5 Raptor Lake Refresh generation.

The manufacturing process differs sharply. AMD uses a 4 nm process from TSMC. Intel uses a 10 nm process from its own foundry. The die sizes also differ: AMD measures 195 mm², Intel measures 215 mm². The smaller process node and die give AMD a potential efficiency advantage, though the database does not record power consumption figures beyond the 65 W TDP shared by both parts.

Cache layouts differ. Both parts use 80 KB of L1 cache per core. The L2 cache differs: AMD uses 1 MB per core, while Intel uses 1.25 MB per core. The L3 cache differs more significantly: AMD uses 8 MB, while Intel uses 20 MB shared. Intel's larger L3 cache helps explain its wins in data-heavy workloads like compression and encryption.

The generation naming reflects different design philosophies. AMD's Ryzen AI 400 series targets a unified Zen 5 architecture with a mix of full and compact cores. Intel's Raptor Lake Refresh extends the previous generation's hybrid design, adding more cores and a larger shared cache. Both parts support ECC memory, but the platform differences, AM5 versus Socket 1700, mean they are not interchangeable.

The release dates differ, with the Intel part entering the market earlier than the AMD part. The production status for both is listed as Active.

The Verdict

The data points to a clear split based on workload type. The Intel Core i5-14400 is the stronger multi-threaded processor, winning the multithread test at 25080 versus 23487, and dominating floating point math at 61549 versus 45711, a 25.7% margin. It also leads in integer math, data encryption, data compression, physics, and random string sorting. For users running heavily parallel workloads, rendering, or number-crunching tasks, the Intel part delivers more throughput.

The AMD Ryzen AI 5 440G is the stronger single-threaded processor. It scores 4060 in the single-thread tests, 8.5% ahead of Intel's 3741. It also wins prime number finding by 12.5% and extended instructions by 4.2%. Its 89th percentile ranking versus Intel's 82nd, combined with an average benchmark score of 46187 versus 32115, indicates that the AMD part performs closer to high-end rivals like the Intel Core i9-13900HX, which sits just 0.2% behind in average score.

The specification differences reinforce the benchmark conclusions. Intel's 10 cores and 16 threads provide the raw parallelism for its throughput wins. AMD's higher boost clock and smaller 4 nm process support its single-thread efficiency. Intel's 20 MB of shared L3 cache versus AMD's 8 MB explains the Intel advantage in cache-sensitive workloads. AMD's unlocked multiplier and newer socket position it for a different kind of user.

The verdict from the recorded data: choose the Intel Core i5-14400 for multi-threaded compute and cache-heavy workloads. Choose the AMD Ryzen AI 5 440G for single-thread responsiveness, extended instruction efficiency, and a higher overall performance percentile. Both parts carry a 65 W TDP and support ECC memory, but they serve different performance priorities.
