AMD Ryzen 5 PRO 8640HS vs AMD Ryzen Embedded 9700X Comparison

The Verdict

The database record for these two AMD processors presents a sharp contrast in positioning and available evidence. The AMD Ryzen 5 PRO 8640HS, a mobile Hawk Point part on Zen 4, has a complete benchmark profile with 17 recorded scores and an 80th percentile rank among all CPUs. The AMD Ryzen Embedded 9700X, a desktop Granite Ridge part on Zen 5, has no recorded benchmark scores in the database, an average score of zero, and a 50th percentile rank that reflects its incomplete data profile rather than actual performance.

Given the absence of recorded measurements for the Embedded 9700X, the data cannot support a direct performance comparison. The 8640HS offers 6 cores, 12 threads, a 3.50 GHz base clock, and a 4.90 GHz boost clock, with a 28 W TDP. The Embedded 9700X offers 8 cores, 16 threads, a 3.80 GHz base clock, and a 5.50 GHz boost clock, with a 65 W TDP. The Embedded part has a higher core count, higher clocks, and a larger 32 MB shared L3 cache versus 16 MB on the 8640HS. It also supports PCIe Gen 5 with 24 lanes, while the 8640HS supports PCIe Gen 4 with 20 lanes.

Users who need a validated mobile processor with established benchmark results should select the Ryzen 5 PRO 8640HS. Users who require a desktop embedded processor with higher core counts, higher clocks, newer Zen 5 architecture, and PCIe Gen 5 connectivity should select the Ryzen Embedded 9700X, accepting that its performance profile is not yet recorded in the database.

Architecture Differences

The two processors come from different AMD generations and architectures. The Ryzen 5 PRO 8640HS uses Zen 4 architecture under the Hawk Point codename, part of the 8000 series. The Ryzen Embedded 9700X uses Zen 5 architecture under the Granite Ridge codename, part of the 9000 series. Both are fabricated on a 4 nm process node at TSMC, but the physical implementations diverge significantly.

The 8640HS has a die size of 178 mm² with 25,000 million transistors. The Embedded 9700X has a die size of 70.6 mm² with 8,315 million transistors. The smaller die and lower transistor count for the Embedded part reflect a different chiplet or monolithic design approach for the Zen 5 Granite Ridge generation.

Cache hierarchies differ by core. The 8640HS provides 64 KB of L1 cache per core and 1 MB of L2 cache per core, with 16 MB of shared L3 cache. The Embedded 9700X provides 80 KB of L1 cache per core and 1 MB of L2 cache per core, with 32 MB of shared L3 cache. The larger per-core L1 and doubled shared L3 on the Embedded part indicate a more generous cache design.

The memory subsystems are identical in bus width and bandwidth. Both support DDR5 memory on a dual-channel bus with 89.6 GB/s of memory bandwidth. Both also list ECC memory support as true. The PCIe capabilities differ: the 8640HS uses PCIe Gen 4 with 20 lanes from the CPU, while the Embedded 9700X uses PCIe Gen 5 with 24 lanes from the CPU.

The integrated graphics differ. The 8640HS pairs with a Radeon 760M GPU. The Embedded 9700X pairs with a generic Radeon Graphics solution. The market segments also differ: the 8640HS targets mobile systems, while the Embedded 9700X targets desktop embedded applications. The 8640HS has a locked multiplier, while the Embedded 9700X has an unlocked multiplier.

Head-to-Head Benchmarks

The Ryzen 5 PRO 8640HS has a complete set of 17 recorded benchmark scores. The Ryzen Embedded 9700X has no recorded benchmarks, so a direct head-to-head comparison cannot use matched measurements. The analysis below interprets the 8640HS scores in absolute terms and notes where the Embedded part's specification advantages would apply, based solely on the recorded data.

The 8640HS achieves a Cinebench R23 multi-core score of 18,104 and a single-core score of 2,555. In Cinebench R20, it scores 7,603 multi-core and 1,073 single-core. In Cinebench R15, it scores 1,824 multi-core and 257 single-core. These results place the processor at the 80th percentile among all CPUs in the database. Its average benchmark score across all recorded tests is 28,478.

Against its nearest rivals, the 8640HS shows tight clustering. The Intel Xeon E-2436 has an average score of 28,530, a delta of -0.2% relative to the 8640HS. The AMD Ryzen 7 PRO 6850HS scores 28,549, also -0.2%. The Intel Core 5 220H scores 28,574, -0.3%. The AMD Ryzen 7 PRO 6850U scores 28,379, +0.3% relative to the 8640HS. These deltas indicate that the 8640HS sits within a narrow band of performance among its closest competitors, with differences under one percent in either direction.

PassMark results for the 8640HS show strength in specific workloads. The multi-thread score is 21,465, while single-thread scores are recorded at 3,561. Integer math scores 69,839, floating-point math scores 43,019, and extended instructions score 18,507. Data compression scores 246,446, data encryption scores 14,962, and random string sorting scores 30,235. Physics scores 1,043, and finding prime numbers scores 71.

The Embedded 9700X has no benchmark scores in the database. Its percentile of 50 and average score of zero reflect missing data, not measured parity. The specification sheet shows a higher core count, higher base and boost clocks, and a larger L3 cache, all of which typically contribute to higher multi-threaded throughput. However, without recorded measurements, the database cannot confirm any performance advantage.

The 8640HS wins every recorded benchmark by default because the Embedded 9700X has no scores. The Embedded 9700X wins on specifications: 2 more cores, 4 more threads, a 0.30 GHz higher base clock, a 0.60 GHz higher boost clock, double the L3 cache, and PCIe Gen 5 support. The 8640HS wins on portability and power: a 28 W TDP versus 65 W, and a mobile market segment. The database records zero benchmark wins for each part in the head-to-head comparison field, as no matched tests exist.

For users relying on validated measurements, the 8640HS is the only part with data. For users requiring the Embedded 9700X's specifications, the performance profile remains unverified in the database. The data indicates that the 8640HS performs competitively against its nearest rivals, with all deltas between -0.3% and +0.3%, confirming that its 80th percentile ranking is consistent with surrounding processors in the database.
