AMD Ryzen 7 PRO 9745 vs AMD Ryzen AI Max+ 395 Comparison

The Verdict

The benchmark data splits these two AMD processors cleanly along core-count and workload lines. The AMD Ryzen AI Max+ 395 wins 9 of the 11 recorded head-to-head tests, while the AMD Ryzen 7 PRO 9745 takes the remaining 2, both of which are single-threaded tests. The AI Max+ 395 is the clear choice for multi-threaded, data-heavy, or floating-point workloads, as its 16 cores and 32 threads produce leads ranging from roughly 44% to 72% across the Passmark suite. The Ryzen 7 PRO 9745 is the pick for single-thread responsiveness, where it leads by 10.3% in the Passmark single-thread test, and for anyone needing a workstation platform with PCIe Gen 5 connectivity on Socket AM5.

The database places both CPUs at the 95th percentile among all processors, so neither is a weak option. The AI Max+ 395 posts an average benchmark score of 77740, while the Ryzen 7 PRO 9745 averages 74761. That 4% gap in average score favors the larger chip, but the smaller one holds its own in latency-sensitive single-core work. Buyers should select based on workload: if the task scales across cores, the AI Max+ 395 is the data-backed winner; if the task is largely single-threaded, the Ryzen 7 PRO 9745 is the better fit.

Architecture Differences

Both processors share the same Zen 5 architecture, but they are implemented in different packages with different design goals. The AMD Ryzen AI Max+ 395 is built on the Strix Halo platform, codename Strix Halo, and uses a 4 nm process from TSMC. It has 16 cores and 32 threads, with a base clock of 3.00 GHz and a boost clock of 5.10 GHz. Its L1 cache is 80 KB per core, L2 is 1 MB per core, and L3 is 64 MB shared. The chip is split across two dies, each measuring 70.6 mm², for a total die size of 2x 70.6 mm². Memory support is LPDDR5X over a quad-channel bus, delivering 256.0 GB/s of bandwidth, with ECC support. The integrated graphics are the Radeon 8060S, and the socket is AMD Socket FP11, a mobile platform. It has PCIe Gen 4 with 16 lanes from the CPU.

The AMD Ryzen 7 PRO 9745 is a Granite Ridge part, also on a 4 nm TSMC process, but designed for the server and workstation segment. It has 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.40 GHz. Cache amounts are identical per core for L1 and L2, but L3 is halved to 32 MB shared. The die size is a single 70.6 mm² chip, and the transistor count is 8,315 million. Memory support is DDR5 over a dual-channel bus, yielding 89.6 GB/s of bandwidth, also with ECC. The integrated graphics are simply called Radeon Graphics, and the socket is AMD Socket AM5. This chip offers PCIe Gen 5 with 24 lanes from the CPU, a notable upgrade over the AI Max+ 395's PCIe Gen 4.

The most consequential architectural differences are the core count, the memory bus width, and the PCIe generation. The AI Max+ 395 doubles the cores and threads, and its quad-channel LPDDR5X memory provides nearly three times the bandwidth of the Ryzen 7 PRO 9745's dual-channel DDR5 (256.0 GB/s versus 89.6 GB/s). Conversely, the Ryzen 7 PRO 9745 has a higher boost clock (5.40 GHz versus 5.10 GHz) and a higher base clock (3.80 GHz versus 3.00 GHz), which explains its single-thread advantage. The Ryzen 7 PRO 9745 also benefits from PCIe Gen 5, which the AI Max+ 395 lacks.

Where Each One Wins

The AMD Ryzen AI Max+ 395 dominates in multi-threaded and memory-intensive operations. Its 16 cores and 32 threads, combined with quad-channel memory, make it the stronger choice for video encoding, 3D rendering, scientific simulations, and any workload that can use many threads simultaneously. The data shows its largest win in the Passmark physics test, where it scores 3481 versus 2026, a 71.8% advantage. It also leads by 61.6% in integer math, 61.2% in prime number finding, and 56.1% in floating-point math. For data compression and encryption, the AI Max+ 395 is ahead by 51.1% and 55.2%, respectively. The recorded benchmark scores indicate that this processor is built for throughput.

The AMD Ryzen 7 PRO 9745 wins only in the single-threaded Passmark tests, scoring 4624 versus 4147, a 10.3% lead. This makes it the better choice for lightly threaded applications, legacy software, or tasks where a single core's speed dictates responsiveness, such as certain database queries or interactive workloads. Additionally, its Socket AM5 platform and PCIe Gen 5 support make it more suitable for workstation builds that require high-speed storage or expansion cards, even if the CPU itself has fewer cores. The Ryzen 7 PRO 9745 also has a higher TDP at 65 watts versus the AI Max+ 395's 55 watts, which may allow for sustained single-core boost behavior, though the database does not record power consumption directly.

Head-to-Head Benchmarks

The head-to-head results in the database are one-sided, with the AMD Ryzen AI Max+ 395 winning every multi-threaded test. The largest single margin is in the Passmark physics test, where the AI Max+ 395 scores 3481 against the Ryzen 7 PRO 9745's 2026, a 71.8% delta. The integer math test is nearly as decisive: 200665 versus 124167, a 61.6% lead. Prime number finding shows a 61.2% gap (303 versus 188), while floating-point math is 56.1% ahead (128682 versus 82461). Data encryption sees a 55.2% advantage (35455 versus 22848), and random string sorting is 54.8% better (76177 versus 49219). Extended instructions follow at 53.1% (56346 versus 36800), and data compression is 51.1% higher (690650 versus 457211). The Passmark multithread score rounds out the multi-core sweep with a 43.8% lead (54934 versus 38201).

The only two tests where the AMD Ryzen 7 PRO 9745 comes out ahead are the identical Passmark single-thread and singlethread tests, both scoring 4624 against the AI Max+ 395's 4147, a 10.3% advantage. This is consistent with its higher boost clock of 5.40 GHz versus 5.10 GHz. The AI Max+ 395 compensates for that single-core deficit with its 16-core design, which explains why its average benchmark score (77740) is about 4% higher than the Ryzen 7 PRO 9745's (74761). The data shows a clear trade-off: raw single-core speed versus massive parallel throughput.
