AMD Ryzen 5 PRO 7645 vs AMD Ryzen AI 7 PRO 360 Comparison

The AMD Ryzen AI 7 PRO 360 and AMD Ryzen 5 PRO 7645 are two very different interpretations of a PRO-series processor. The data shows a clear split: the Ryzen 5 PRO 7645 dominates in raw multi-threaded throughput and legacy single-core tests, while the Ryzen AI 7 PRO 360 counters with wins in specific math workloads and a modern single-thread metric. Both CPUs land at the 83rd percentile among all CPUs, yet their average benchmark scores tell a story of near-parity (32662 vs 32446) despite wildly different architectures. This comparison walks through the benchmark deltas, architectural choices, and use-case implications from the data.

Head-to-Head Benchmarks

The Ryzen 5 PRO 7645 wins the overall head-to-head count decisively, taking 11 of 15 benchmark comparisons. Its biggest margin comes in Cinebench R23 multi-core, where it scores 21710 against the Ryzen AI 7 PRO 360's 13794 — a 36.5% advantage. The single-core R23 result is equally lopsided: 3065 vs 1958, a 36.1% delta in favor of the Ryzen 5. These are not marginal differences; the Ryzen 5 PRO 7645 delivers roughly a third more performance in both Cinebench R23 tests.

The pattern repeats across several Passmark workloads. In find prime numbers, the Ryzen 5 PRO 7645 scores 198 versus 76, a 61.6% lead — the largest single delta in the entire comparison. Data encryption shows a 20.4% edge (16657 vs 13264), and physics follows at 21.3% (1598 vs 1257). The Ryzen 5 also leads in random string sorting by 17.8% (34557 vs 28390), extended instructions by 17.3% (21813 vs 18029), and multithread by 13.2% (25489 vs 22125). Even in data compression, where the gap narrows, the Ryzen 5 still wins by 10.4% (286298 vs 256603).

The Ryzen AI 7 PRO 360's four wins are concentrated in specific math and single-thread areas. Its best result is Passmark single-thread: 3862 vs 3652, a 5.8% advantage. The same delta appears in the duplicate singlethread entry. In floating point math, the Ryzen AI 7 wins 46996 vs 45202 (4%), and integer math goes its way by 3.5% (77414 vs 74782). Notice that the Ryzen AI 7's single-thread win in Passmark contradicts the Cinebench R15 single-core result, where the Ryzen 5 wins 308 vs 271 (12%). The data offers two different single-thread narratives depending on the benchmark.

Architecture Differences

The two processors represent distinct design philosophies. The Ryzen AI 7 PRO 360 uses Zen 5 architecture on a 4 nm TSMC node, codename Strix Point, with a die size of 233 mm². The Ryzen 5 PRO 7645 uses Zen 4 on a 5 nm TSMC node, codename Raphael, with a die size of 71 mm² and 6,570 million transistors. The Ryzen AI 7 is built for mobile efficiency with a 28 W TDP on AMD Socket FP8, while the Ryzen 5 is a 65 W part on AMD Socket AM5, classified for the server/workstation market segment.

Core counts differ: the Ryzen AI 7 has 8 cores and 16 threads, while the Ryzen 5 has 6 cores and 12 threads. Cache layout is notably different — the Ryzen AI 7 uses 80 KB L1 per core and 1 MB L2 per core, with only 8 MB L3, whereas the Ryzen 5 has 64 KB L1 per core, 1 MB L2 per core, and a much larger 32 MB shared L3. The process node advantage belongs to the Ryzen AI 7 (4 nm vs 5 nm), but the Ryzen 5 compensates with higher clock speeds: 3.80 GHz base and 5.10 GHz boost versus 2.00 GHz base and 5.00 GHz boost.

Memory support diverges as well. The Ryzen AI 7 supports DDR5 and LPDDR5X with 89.6 GB/s bandwidth, while the Ryzen 5 supports only DDR5 at 83.2 GB/s. Both have dual-channel memory buses and ECC support. PCIe connectivity favors the Ryzen 5 significantly: it offers Gen 5 with 24 lanes, while the Ryzen AI 7 is limited to Gen 4 with 16 lanes. Integrated graphics also differ — the Ryzen AI 7 features Radeon 880M, while the Ryzen 5 lists simply "Radeon Graphics."

Where Each One Wins

The Ryzen 5 PRO 7645 wins in every Cinebench test, both R15 and R23, single and multi-core. It also wins in Passmark data compression, encryption, extended instructions, find prime numbers, multithread, physics, and random string sorting. This makes it the clear choice for workloads that stress sustained multi-core execution, CPU-bound rendering, and cryptographic or compression tasks. The 61.6% lead in find prime numbers suggests particular strength in integer-heavy primality testing, while the 21.3% physics win points to better performance in simulated physics calculations.

The Ryzen AI 7 PRO 360 wins in Passmark floating point math, integer math, and single-thread tests. Its 5.8% single-thread advantage in Passmark is notable because it comes despite a lower boost clock (5.00 GHz vs 5.10 GHz). The 4% floating point win and 3.5% integer math win indicate that Zen 5's architectural improvements deliver real gains in these specific math operations, even at lower clock speeds and with fewer L3 cache. For workloads that are heavily dependent on floating point precision or single-threaded responsiveness in Passmark's methodology, the Ryzen AI 7 holds an edge.

The wins distribution — 11 for the Ryzen 5, 4 for the Ryzen AI 7 — tells a story of general-purpose dominance versus targeted strengths. The Ryzen 5's higher TDP and desktop-oriented socket clearly translate into broader benchmark superiority, while the Ryzen AI 7's wins suggest architectural efficiency rather than raw throughput.

Specification Differences

The core specifications diverge on nearly every measurable field. Core count: 8 vs 6. Threads: 16 vs 12. Base clock: 2.00 GHz vs 3.80 GHz. Boost clock: 5.00 GHz vs 5.10 GHz. TDP: 28 W vs 65 W. Socket: FP8 vs AM5. Architecture: Zen 5 vs Zen 4. Process node: 4 nm vs 5 nm. Die size: 233 mm² vs 71 mm². Transistors: not listed for the Ryzen AI 7, but 6,570 million for the Ryzen 5.

Cache differs dramatically: 80 KB L1 per core for the Ryzen AI 7 versus 64 KB for the Ryzen 5, same 1 MB L2 per core, but L3 is 8 MB vs 32 MB shared. Memory bandwidth: 89.6 GB/s vs 83.2 GB/s. PCIe: Gen 4 with 16 lanes vs Gen 5 with 24 lanes. Integrated graphics: Radeon 880M vs Radeon Graphics. Market segment: Mobile vs Server/Workstation. Release date: 2025-01-05 vs 2023-06-12. Part numbers differ: 100-000001571 vs 100-000000600. Both have ECC support, dual-channel memory, and locked multipliers.

The Verdict

The data points to a straightforward choice for most users: the AMD Ryzen 5 PRO 7645 is the stronger processor in the majority of benchmarks. Its 11 wins out of 15 head-to-head comparisons, including every Cinebench test and a 36.5% multi-core lead, make it the default recommendation for compute-heavy workloads. The 61.6% advantage in find prime numbers and consistent wins in encryption, compression, and physics suggest it handles diverse multi-threaded tasks with greater efficiency. The higher 65 W TDP and desktop AM5 socket indicate it is designed for sustained performance rather than power conservation.

The AMD Ryzen AI 7 PRO 360 is not without merit, but its wins are narrower and more specialized. The 5.8% single-thread lead in Passmark and 4% floating point math advantage show Zen 5's architectural maturity, but these do not offset the massive Cinebench deltas. Its 28 W TDP and mobile FP8 socket position it as an efficiency-focused part, and the 89.6 GB/s memory bandwidth with LPDDR5X support suggests it targets thin-and-light systems. For users prioritizing power efficiency, single-thread responsiveness in Passmark, or specific floating point workloads, the Ryzen AI 7 PRO 360 has a case. For everyone else, the benchmark data favors the Ryzen 5 PRO 7645 by a wide margin. Both CPUs sit at the same 83rd percentile, and their average scores differ by less than 1%, but the distribution of wins could not be more different — the Ryzen 5 PRO 7645 is the broad-spectrum performer, while the Ryzen AI 7 PRO 360 wins only where its Zen 5 architecture specifically excels.
