The Verdict

The recorded data presents a clear performance hierarchy. The AMD Ryzen 5 240 wins 14 of 15 head-to-head benchmarks, with its largest margins appearing in data encryption (50.7%), random string sorting (37.9%), and extended instructions (27.6%). The AMD Ryzen AI 7 445 claims exactly one victory, a 3.5% edge in Cinebench R23 single-core.

The Ryzen 5 240 belongs in systems where raw throughput is the priority. Its 22.9% lead in Cinebench R23 multi-core and 25.1% lead in PassMark multithread indicate that heavily threaded workloads such as rendering, compilation, and scientific computing will favor this chip. The Ryzen AI 7 445, with its 45-watt lower TDP of 28 versus 45, suits power-constrained mobile designs where the single-core win in Cinebench R23 matters more than the broader multi-core deficit. Buyers seeking ECC memory support have only one option in this pair: the Ryzen AI 7 445.

Neither chip offers an unlocked multiplier, and both ship as active mobile parts. The Ryzen 5 240's higher percentile ranking (84 versus 79) and higher average score (33542 versus 26936) make it the default choice for performance-oriented configurations. The Ryzen AI 7 445 counters with a newer architecture, a lower TDP, and ECC support, but the benchmark data consistently shows it trailing in almost every measurable task.

Head-to-Head Benchmarks

The Cinebench suite establishes the overall pattern. In Cinebench R15 multi-core, the Ryzen 5 240 scores 2078 against 1723, a 20.6% margin. The R23 multi-core test widens the gap slightly to 22.9% (13013 versus 10590). Single-core in R15 also favors the Ryzen 5 240, with 270 versus 254, a 6.3% lead. The sole reversal appears in R23 single-core, where the Ryzen AI 7 445 scores 1806 versus 1742, a 3.5% advantage.

PassMark results reinforce the Ryzen 5 240's dominance. The largest single margin is data encryption: 15849 versus 10519, a 50.7% lead. Random string sorting shows a 37.9% gap (32385 versus 23488). Integer math trails at 25.5% (73189 versus 58332), and multithread sits at 25.1% (22658 versus 18115). Extended instructions deliver a 27.6% gap (20201 versus 15826), while data compression shows 24.2% (267963 versus 215812). Find prime numbers shows a 25% difference (70 versus 56). Floating point math is closer at 15.1% (45301 versus 39362). The physics test shows an 8.6% gap (1060 versus 976). The smallest PassMark margin is single-thread, where the Ryzen 5 240 scores 3675 versus 3591, a 2.3% lead.

The benchmark data indicates that the Ryzen 5 240's advantage grows with workload intensity. Encryption and sorting tasks, which stress memory access patterns and instruction throughput, show the largest deltas. The Ryzen AI 7 445's single win in R23 single-core suggests its Zen 5 architecture has a higher peak single-thread capability, but this does not translate into broader single-thread dominance in PassMark, where the Ryzen 5 240 still leads by 2.3%.

Specification Differences

The two processors share the same core and thread counts: 6 cores and 12 threads each. Both use dual-channel memory with 89.6 GB/s bandwidth and both fit the AMD Socket FP8. The Ryzen 5 240 draws 45 W TDP, while the Ryzen AI 7 445 draws 28 W. Clock speeds differ substantially: the Ryzen 5 240 runs at 4.30 GHz base and 5.00 GHz boost, while the Ryzen AI 7 445 runs at 2.00 GHz base and 4.60 GHz boost.

Memory support diverges on two points. The Ryzen 5 240 supports DDR5 only, while the Ryzen AI 7 445 supports DDR5 and LPDDR5X. ECC memory is absent on the Ryzen 5 240 but present on the Ryzen AI 7 445. PCIe lane counts also differ: the Ryzen 5 240 provides Gen 4 with 20 lanes, while the Ryzen AI 7 445 provides Gen 4 with 14 lanes.

Integrated graphics differ as well. The Ryzen 5 240 pairs with a Radeon 760M, while the Ryzen AI 7 445 pairs with a Radeon 840M. The release dates place the Ryzen 5 240 at January 5, 2025, and the Ryzen AI 7 445 at January 4, 2026. The Ryzen 5 240 has a listed transistor count of 25,000 million and a die size of 178 mm²; the Ryzen AI 7 445 has no recorded transistor or die size data. Part numbers are 100-000001727 for the Ryzen 5 240 and 100-000001935 for the Ryzen AI 7 445.

Architecture Differences

The Ryzen 5 240 uses Zen 4 architecture with the Hawk Point codename, while the Ryzen AI 7 445 uses Zen 5 architecture with the Gorgon Point codename. Both are built on TSMC's 4 nm process. The generational naming reflects this split: the Ryzen 5 240 belongs to the Ryzen 5 (Zen 4 (Hawk Point)) generation, and the Ryzen AI 7 445 belongs to the Ryzen AI 400 (Zen 5 / Zen 5c) generation.

Cache layouts differ in two meaningful ways. The L1 cache is larger on the Ryzen AI 7 445 at 80 KB per core versus 64 KB per core on the Ryzen 5 240. L2 cache is identical at 1 MB per core. L3 cache, however, favors the Ryzen 5 240 heavily: 16 MB shared versus 4 MB on the Ryzen AI 7 445. This 12 MB difference in L3 likely explains part of the Ryzen 5 240's advantage in data-heavy workloads like encryption and random string sorting.

The Ryzen AI 7 445's Zen 5 architecture introduces a hybrid core design (Zen 5 / Zen 5c), which may account for its lower base clock of 2.00 GHz. The Ryzen 5 240's Zen 4 design operates at a much higher 4.30 GHz base clock. The Ryzen AI 7 445 also adds ECC support, which neither Zen 4 Hawk Point part offers in this comparison.

Where Each One Wins

The Ryzen 5 240 wins in every multi-threaded and most single-threaded scenarios. Its 20.6% lead in Cinebench R15 multi-core, 22.9% in Cinebench R23 multi-core, and 25.1% in PassMark multithread make it the clear choice for rendering, video encoding, batch processing, and any workload that scales across all 12 threads. The 50.7% encryption advantage and 37.9% random string sorting advantage point to strong performance in database operations, compression tasks, and security-related computations. The 27.6% extended instructions lead suggests the Ryzen 5 240 also handles SIMD-heavy code more efficiently.

The Ryzen AI 7 445 wins only in Cinebench R23 single-core, with a 3.5% margin. This indicates that for lightly threaded tasks that rely on a single core's peak performance, such as some legacy applications or lightly optimized software, the Zen 5 architecture provides a modest edge. Its 28 W TDP also makes it the more power-efficient option for thin-and-light laptops, despite the lower overall performance. The ECC memory support positions it for systems where data integrity is critical, such as small-scale servers or workstations that require error correction.

The Ryzen 5 240's 84th percentile ranking versus the Ryzen AI 7 445's 79th percentile confirms that the older Zen 4 part occupies a higher position in the overall CPU landscape. For users who prioritize maximum throughput in the broadest range of tasks, the Ryzen 5 240 is the data-backed winner. For users who need ECC memory, lower power consumption, and a small single-core advantage in a specific benchmark, the Ryzen AI 7 445 has a narrow but real role.
