AMD Ryzen 5 7640HS vs AMD Ryzen 7 PRO 5755GE Comparison

AMD Ryzen 5 7640HS and AMD Ryzen 7 PRO 5755GE occupy the same 81st percentile in the database, yet their benchmark profiles diverge sharply. The 7640HS wins 10 of the 15 recorded head-to-head tests, while the 5755GE takes 5, but the margin distribution tells a more nuanced story than the raw win count suggests. The 7640HS excels in latency-sensitive and single-threaded workloads, whereas the 5755GE dominates sustained multi-threaded rendering and integer-heavy tasks.

Where Each One Wins

The AMD Ryzen 5 7640HS is the clear winner for workloads that reward high clock speeds and modern instruction efficiency. Its single-thread Passmark score of 3654 beats the 5755GE’s 3353 by 9%, and the Cinebench R15 single-core result of 269.5 versus 252 gives it a 6.9% edge. The 7640HS also leads in physics simulation, scoring 1155 against 841, a commanding 37.3% advantage that reflects its per-core strength. In random string sorting, the 7640HS posts 31654 versus 27373, a 15.6% lead, and it handles extended instruction sets 20.7% better (20556 versus 17029). Data compression favors the 7640HS at 269524 versus 252937, a 6.6% gain, and the multithread Passmark test shows 22979 versus 20870, a 10.1% advantage.

The AMD Ryzen 7 PRO 5755GE takes the crown in raw multi-threaded rendering and integer throughput. Its Cinebench R23 multi-core score of 17759 dwarfs the 7640HS’s 12554, a 29.3% deficit for the latter. The R23 single-core result is even more lopsided: 2507 versus 1715.5, meaning the 5755GE leads by 31.6%. This is surprising given the 7640HS’s higher boost clock, but the data is unambiguous. The 5755GE also wins integer math with 84004 versus 73284, a 12.8% lead, and floating-point math with 46589 versus 45220, a modest 2.9% edge. Data encryption goes to the 5755GE at 16937 versus 15867, a 6.3% advantage.

Architecture Differences

The two processors come from different generations and target different physical sockets. The 7640HS is a 7000-series mobile chip built on Zen 4 architecture, codenamed Phoenix, using a 4 nm TSMC process. The 5755GE is a 5000-series desktop part on Zen 3, codenamed Cezanne, using a 7 nm TSMC process. The node difference is stark: 4 nm versus 7 nm, which explains why the 7640HS achieves higher clocks despite similar transistor counts. The 7640HS packs 25,000 million transistors on a 178 mm² die, while the 5755GE uses 10,700 million on a 180 mm² die. The newer node allows the 7640HS to fit more than double the transistors in a slightly smaller area.

Core and cache configurations differ significantly. The 7640HS has 6 cores and 12 threads, while the 5755GE has 8 cores and 16 threads. L1 cache is identical at 64 KB per core, but L2 differs: the 7640HS has 1 MB per core, the 5755GE has 512 KB per core. L3 cache is shared at 16 MB on both, but the 5755GE’s total is listed as 16 MB without per-core designation, whereas the 7640HS specifies 16 MB shared. The 5755GE’s extra two cores are its main weapon for multi-threaded tasks, but each core has less L2 cache, which may contribute to its lower single-thread performance.

Memory support is a major divide. The 7640HS uses DDR5 with dual-channel support and a memory bandwidth of 89.6 GB/s. The 5755GE uses DDR4 with dual-channel support and a memory bandwidth of 51.2 GB/s. The 7640HS supports ECC memory; the 5755GE does not. PCIe generations also differ: the 7640HS offers Gen 4 with 20 lanes (CPU only), while the 5755GE offers Gen 3 with 16 lanes (CPU only). Integrated graphics differ as well: the 7640HS has Radeon 760M, the 5755GE has Radeon Vega 8.

Socket compatibility is another fundamental split. The 7640HS uses AMD Socket FP8, a mobile platform, and its part numbers include multiple FP7 variants. The 5755GE uses AMD Socket AM4, a desktop platform, with a single part number. The 5755GE has a release date of 2024-09-04, while the 7640HS has no recorded release date in the database. Both are currently marked as Active production.

FAQ

Q: Which processor has the higher boost clock?

A: The AMD Ryzen 5 7640HS boosts to 5.00 GHz, while the AMD Ryzen 7 PRO 5755GE boosts to 4.60 GHz. The base clocks are 4.30 GHz for the 7640HS and 3.20 GHz for the 5755GE.

Q: Why does the 5755GE win Cinebench R23 multi-core despite losing most other tests?

A: The 5755GE has 8 cores and 16 threads versus 6 cores and 12 threads on the 7640HS. In the R23 multi-core test, the 5755GE scores 17759 against 12554, a 29.3% advantage, because the workload scales well with the extra cores. The 7640HS wins other multithread tests like Passmark multithread (22979 versus 20870) because its higher clocks and newer architecture compensate for fewer cores in that specific workload.

Q: Which processor is better for single-threaded performance?

A: The 7640HS wins in Passmark single-thread (3654 versus 3353, a 9% lead) and Cinebench R15 single-core (269.5 versus 252, a 6.9% lead). However, the 5755GE wins Cinebench R23 single-core with 2507 versus 1715.5, a 31.6% margin. The discrepancy likely stems from benchmark differences, but the majority of single-thread tests favor the 7640HS.

Q: What memory types do these processors support?

A: The 7640HS supports DDR5 with dual-channel memory and a bandwidth of 89.6 GB/s. The 5755GE supports DDR4 with dual-channel memory and a bandwidth of 51.2 GB/s. ECC memory is supported only on the 7640HS.

Q: Are these processors on the same socket?

A: No. The 7640HS uses AMD Socket FP8, which is a mobile socket. The 5755GE uses AMD Socket AM4, which is a desktop socket. They are not interchangeable.

Q: How do their integrated graphics compare?

A: The 7640HS features Radeon 760M integrated graphics, while the 5755GE features Radeon Vega 8. The database does not include direct graphics benchmarks for either, so the comparison is limited to naming the different iGPU models.

The pattern is consistent: the 7640HS wins on latency, encryption-adjacent tasks, and single-thread Passmark tests, while the 5755GE wins on Cinebench rendering and integer-heavy workloads. The 5755GE’s two extra cores and larger thread count give it a decisive edge in Cinebench, which scales almost linearly with core count. The 7640HS compensates with a 4 nm node, higher clocks, and larger L2 cache, which shows up in physics, prime number calculations, and extended instruction tests. The average benchmark score in the database is 30390 for the 7640HS and 29656 for the 5755GE, a 2.4% gap in favor of the mobile part, despite the 5755GE’s Cinebench dominance. Both processors sit at the 81st percentile of all CPUs, and their nearest rivals include similar-scoring parts like the AMD Ryzen 7 7736U (0.1% delta from the 7640HS) and the AMD Ryzen 5 9600X (0.2% delta from the 5755GE). The data suggests the 7640HS is the more balanced overall performer, while the 5755GE is purpose-built for multi-threaded rendering and integer compute.
