AMD Ryzen 5 8500GE vs AMD Ryzen 5 PRO 5655G Comparison

Head-to-Head Benchmarks

The benchmark data splits these two six-core parts into distinct profiles. The AMD Ryzen 5 8500GE wins 14 of the 17 recorded comparisons, while the AMD Ryzen 5 PRO 5655G takes 3. The most decisive victory for the 8500GE is in PassMark physics, where it scores 1150 against 686, a 40.3% lead. That is a massive gap for a workload that often reflects real-world responsiveness and simulation logic.

The 8500GE also dominates PassMark single-thread performance with 3914 versus 3241, a 17.2% advantage. This carries over to Cinebench single-core tests, where the 8500GE leads by 3.8-3.9% across R15, R20, and R23. In Cinebench R23 single-core, the scores are 2532 against 2435. The boost clock difference explains much of this: the 8500GE reaches 5.00 GHz while the PRO 5655G tops out at 4.40 GHz.

Multithreaded Cinebench results follow the same pattern, but with smaller margins. The 8500GE scores 1808 in R15 multicore versus 1738, a 3.9% lead. In R20, it is 7534 versus 7244, a 3.8% gap. In R23, the 8500GE posts 17940 versus 17249, again 3.9% ahead. The PassMark multithread test shows a larger spread: 21135 versus 19129, a 9.5% advantage for the 8500GE.

The PRO 5655G fights back in specific integer-heavy and cryptographic workloads. PassMark integer math goes to the PRO 5655G with 67561 versus 62666, a 7.8% lead. Data encryption is even stronger: 15253 versus 14197, a 7.4% margin. Data compression also favors the PRO 5655G, 255608 versus 246397, a 3.7% edge.

The remaining tests are closer. Floating-point math is nearly even: 39065 for the 8500GE versus 38649, a 1.1% lead. Extended instructions are essentially tied at 17962 versus 17944, a 0.1% difference. The 8500GE wins random string sorting by 14.4% (29501 versus 25253) and find prime numbers by a wide 38% (79 versus 49). Overall average benchmark scores are nearly identical: the PRO 5655G sits at 28032 and the 8500GE at 27712, with each part landing in the 79-80th percentile of all CPUs in the database.

Architecture Differences

The two processors come from different generations and platforms. The AMD Ryzen 5 PRO 5655G uses Zen 3 architecture on the Cezanne codename, built on a 7 nm TSMC process. It packs 10,700 million transistors into a 180 mm² die. The AMD Ryzen 5 8500GE uses Zen 4 architecture on the Phoenix2 codename, built on a 4 nm TSMC process, with 20,900 million transistors in a smaller 137 mm² die. The node shrink and transistor count increase are substantial, but the 5655G still competes well in several tests.

Cache layouts differ. Both have 64 KB of L1 per core, but the L2 cache doubles on the 8500GE: 1 MB per core versus 512 KB per core. L3 is 16 MB on each, though the 5655G lists it as 16 MB total while the 8500GE lists 16 MB shared. Memory support also diverges. The PRO 5655G uses DDR4 with dual-channel memory and 51.2 GB/s bandwidth. The 8500GE uses DDR5 with dual-channel memory and 83.2 GB/s bandwidth. Both support ECC memory.

PCIe generations differ: the 5655G offers Gen 3 with 16 CPU lanes, while the 8500GE offers Gen 4 with 14 CPU lanes. The integrated graphics are different as well: Radeon Vega 7 on the 5655G versus Radeon 740M on the 8500GE. Sockets are not interchangeable: the 5655G is on AMD Socket AM4, the 8500GE on AMD Socket AM5. The 8500GE has an unlocked multiplier; the 5655G does not. The 5655G is classified as a desktop part, while the 8500GE is listed under the mobile segment, despite both being active in production.

Where Each One Wins

The AMD Ryzen 5 8500GE is the clear winner for most everyday computing and productivity tasks. Its single-thread advantage of 17.2% in PassMark and 3.8-3.9% in Cinebench makes it the better choice for applications that rely on one or two fast cores. The physics test result, 1150 versus 686, suggests a strong edge in simulation and gaming-adjacent workloads. The 9.5% lead in PassMark multithread also makes it the better pick for general multi-threaded work like rendering or video encoding, where the higher boost clock and newer architecture pay off.

The AMD Ryzen 5 PRO 5655G wins in three specific areas: integer math, data encryption, and data compression. The 7.8% lead in integer math and the 7.4% lead in encryption point to strengths in database operations, file archiving, and security-related processing. For users who run encryption-heavy workloads or compress large datasets regularly, the PRO 5655G offers measurable gains. Its 65 W TDP also means it is designed for sustained desktop operation, while the 8500GE's 35 W TDP reflects a mobile-oriented efficiency target.

The 8500GE also wins in random string sorting by 14.4% and find prime numbers by 38%, indicating better memory subsystem efficiency and integer execution on certain algorithm patterns. Floating-point math is nearly identical, so scientific or mathematical workloads see no significant difference between the two.

The Verdict

The data points to the AMD Ryzen 5 8500GE as the stronger overall processor for most users. It wins 14 of 17 benchmarks, including all Cinebench tests, all single-thread tests, and the major multithreaded PassMark test. Its 5.00 GHz boost clock, Zen 4 architecture, DDR5 memory support, and 83.2 GB/s bandwidth give it a modern platform advantage. The 35 W TDP also makes it attractive for compact or low-power builds, even though it is categorized as a mobile part.

The AMD Ryzen 5 PRO 5655G is not without merit. It wins in data compression, data encryption, and integer math, which are meaningful for specific professional workflows. Its 65 W TDP and AM4 socket appeal to those upgrading existing platforms without changing motherboards or memory. The 7.4% encryption lead and 7.8% integer lead are real, not negligible.

Choose the Ryzen 5 8500GE if you prioritize raw speed, single-thread performance, and modern memory technology. Choose the Ryzen 5 PRO 5655G if your workload centers on encryption, compression, or integer math, and if staying on the AM4 platform matters to you. For everything else, the 8500GE is the safer bet based on the recorded benchmarks.
