Architecture Differences

The AMD Ryzen 5 PRO 8645HS belongs to the 8000 series and uses the Zen 4 architecture under the Hawk Point codename. The AMD Ryzen Embedded 9600X belongs to the 9000 series and uses the Zen 5 architecture under the Granite Ridge codename. The database records the Ryzen 5 PRO 8645HS generation as "Ryzen 5 (Zen 4 (Hawk Point))" and the Ryzen Embedded 9600X generation as "Ryzen Embedded (Zen 5 (Granite Ridge))". This places the two parts on different architectural generations, with Zen 5 representing the newer design.

The process node is identical, with both built on TSMC's 4 nm process. Transistor counts and die sizes differ substantially. The Ryzen 5 PRO 8645HS has 25,000 million transistors on a 178 mm² die, while the Ryzen Embedded 9600X has 8,315 million transistors on a 70.6 mm² die. The mobile chip uses a significantly larger physical package despite fewer architectural changes, while the desktop embedded part crams Zen 5 cores into a much smaller area.

Cache layouts differ in both L1 and L3. The Ryzen 5 PRO 8645HS provides 64 KB of L1 per core and 16 MB of shared L3. The Ryzen Embedded 9600X provides 80 KB of L1 per core and 32 MB of shared L3. Both share 1 MB of L2 per core.

Memory support is similar in that both use DDR5 with a dual-channel memory bus and the same 89.6 GB/s memory bandwidth figure. PCIe connectivity differs: the Ryzen 5 PRO 8645HS uses Gen 4 with 20 CPU lanes, while the Ryzen Embedded 9600X uses Gen 5 with 24 CPU lanes. The embedded part offers both a newer PCIe generation and more lanes.

Integrated graphics differ in naming. The Ryzen 5 PRO 8645HS carries the Radeon 760M, while the Ryzen Embedded 9600X carries a generic Radeon Graphics solution. The database does not record detailed GPU specifications for either.

The market segments and sockets separate these parts physically. The Ryzen 5 PRO 8645HS is a mobile processor on AMD Socket FP7, with part numbers 100-000001315(FP7r2) and 100-000001388(FP7). The Ryzen Embedded 9600X is a desktop-class embedded processor on AMD Socket AM5, with part number 100-000001405E. The multiplier is locked on the mobile chip and unlocked on the embedded chip.

Release dates are recorded for both, with the Ryzen 5 PRO 8645HS releasing in April 2024 and the Ryzen Embedded 9600X in October 2025.

The Verdict

The data separates these two processors by architecture generation, platform, and measured performance availability. The AMD Ryzen 5 PRO 8645HS has a full suite of benchmark results in the database, with an average benchmark score of 30,879 and a percentile ranking of 82 against all CPUs. The AMD Ryzen Embedded 9600X has no recorded benchmark scores, an average benchmark score of 0, and a percentile ranking of 50. Direct comparison of measured performance is therefore not possible from the recorded data.

For anyone selecting a mobile processor, the Ryzen 5 PRO 8645HS is the only viable choice between the two because the Ryzen Embedded 9600X is a desktop embedded part. The Ryzen 5 PRO 8645HS also offers a higher base clock at 4.30 GHz versus 3.90 GHz, which matters for sustained low-load operation. The embedded part counters with a higher boost clock at 5.40 GHz versus 5.00 GHz and double the L3 cache at 32 MB versus 16 MB. The Ryzen 5 PRO 8645HS has a lower TDP at 45 W versus 65 W, which aligns with its mobile positioning.

For embedded desktop applications requiring the newer Zen 5 architecture, the Ryzen Embedded 9600X brings PCIe Gen 5 with 24 lanes, an unlocked multiplier, and a smaller die at 70.6 mm². The absence of benchmark data for the embedded part means its real-world standing against the Ryzen 5 PRO 8645HS cannot be quantified from the database. The verdict from the recorded information is that the Ryzen 5 PRO 8645HS is the measured performer, while the Ryzen Embedded 9600X is the architecturally newer part with unverified performance in the database.

Specification Differences

The two processors differ across several recorded specification fields. Base clock: the Ryzen 5 PRO 8645HS runs at 4.30 GHz, the Ryzen Embedded 9600X at 3.90 GHz. Boost clock: the Ryzen 5 PRO 8645HS reaches 5.00 GHz, the Ryzen Embedded 9600X reaches 5.40 GHz. TDP: 45 W for the mobile part, 65 W for the embedded part.

Socket and platform: AMD Socket FP7 for the Ryzen 5 PRO 8645HS, AMD Socket AM5 for the Ryzen Embedded 9600X. Architecture and codename: Zen 4 with Hawk Point for the mobile chip, Zen 5 with Granite Ridge for the embedded chip. Generation entries reflect this split as "Ryzen 5 (Zen 4 (Hawk Point))" versus "Ryzen Embedded (Zen 5 (Granite Ridge))".

Transistor count: 25,000 million for the Ryzen 5 PRO 8645HS versus 8,315 million for the Ryzen Embedded 9600X. Die size: 178 mm² versus 70.6 mm². L1 cache per core: 64 KB versus 80 KB. L3 cache: 16 MB shared versus 32 MB shared. PCIe: Gen 4 with 20 lanes versus Gen 5 with 24 lanes. Integrated graphics: Radeon 760M versus Radeon Graphics. Market segment: Mobile versus Desktop. Multiplier: locked versus unlocked. Part numbers and release dates also differ.

Identical specifications include cores (6), threads (12), process node (4 nm), foundry (TSMC), L2 cache (1 MB per core), memory support (DDR5), memory bus (dual-channel), memory bandwidth (89.6 GB/s), ECC support (enabled), and production status (Active).

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Ryzen 5 PRO 8645HS against the AMD Ryzen Embedded 9600X. The wins counter for both processors is 0, and the head-to-head benchmark array is empty. This means no single-test comparison can be drawn from the recorded measurements between these two specific models.

The Ryzen 5 PRO 8645HS does have a full benchmark profile. In Cinebench R23, it scores 19,742 in multicore and 2,787 in single-core. In Cinebench R20, the scores are 8,291 multicore and 1,170 single-core. Cinebench R15 shows 1,989 multicore and 280 single-core. PassMark results include a multithread score of 23,569, a single-thread score of 3,858, integer math at 72,740, floating point math at 45,481, and data compression at 265,826. The average benchmark score for this mobile processor is 30,879, placing it at the 82nd percentile of all CPUs in the database.

The Ryzen 5 PRO 8645HS sits between nearby rivals in the database. Its average score of 30,879 is 0.4% above the AMD Ryzen 7 8700F at 30,746, and 0.5% below the Intel Core i7-13700TE at 31,028. It trails the AMD Ryzen 9 8945HS by 0.6% (31,074) and the Intel Core i7-12700F by 0.6% (31,081). These deltas are small, indicating the Ryzen 5 PRO 8645HS lands in a tightly clustered performance band around 30,700 to 31,100 average score.

The Ryzen Embedded 9600X has no benchmark entries in the database, so its average score is recorded as 0 and its percentile as 50. Without recorded measurements, no comparison of its Cinebench or PassMark results against the Ryzen 5 PRO 8645HS can be made. The architectural specifications suggest the Zen 5 part should be examined once benchmark data becomes available, but the database currently offers no numeric basis for that evaluation. The only concrete performance-related facts for the Ryzen Embedded 9600X are its clock speeds, cache sizes, and platform features, none of which translate directly into a measured score.

Given the missing benchmark data for the Ryzen Embedded 9600X, the recorded head-to-head comparison is limited to specification-level differences. The Ryzen 5 PRO 8645HS leads in base clock by 0.40 GHz and carries a lower TDP by 20 W. The Ryzen Embedded 9600X leads in boost clock by 0.40 GHz, L3 cache by 16 MB, L1 cache per core by 16 KB, and PCIe generation and lane count. These specification advantages do not yet have corresponding benchmark confirmation in the database.
