AMD Ryzen 5 7600X vs AMD Ryzen 5 PRO 5655G Comparison

The AMD Ryzen 5 PRO 5655G and the AMD Ryzen 5 7600X are both 6-core, 12-thread desktop processors, but they target very different system builders. The PRO 5655G is a Zen 3 part for the AM4 platform, while the 7600X is a Zen 4 part for the AM5 platform. The benchmark data reveals a clear split: the 7600X dominates in most workloads, but the PRO 5655G posts surprising wins in certain Cinebench tests.

Head-to-Head Benchmarks

The most striking result in the database is the split verdict between the two Cinebench versions. In Cinebench R23 multi-core, the PRO 5655G scores 17,249 against 15,236 for the 7600X, a 13.2% advantage. The single-core R23 result is even more lopsided in favor of the older chip: 2,435 versus 1,965, a 23.9% lead. However, in Cinebench R15, the tables turn completely. The 7600X wins multi-core with 2,517 against 1,738, a 30.9% gap, and single-core with 314 versus 245, a 22% lead. These contradictory results suggest the PRO 5655G performs better under the specific workload characteristics of the R23 test, while the 7600X excels in the R15 test.

Outside of Cinebench, the 7600X is the clear winner across the Passmark suite. The largest margin comes in the find prime numbers test, where the 7600X scores 205 versus just 49 for the PRO 5655G, a 76.1% difference. The physics test also heavily favors the 7600X: 1,824 versus 686, a 62.4% gap. In multithread performance, the 7600X scores 28,390 against 19,129, a 32.6% advantage. Random string sorting shows a 33.1% lead for the 7600X (37,726 versus 25,253). Extended instructions see the 7600X ahead by 25.9% (24,216 versus 17,944), and floating point math by 24.3% (51,025 versus 38,649). Data compression favors the 7600X by 19.6% (317,862 versus 255,608), integer math by 20.3% (84,749 versus 67,561), and data encryption by 17.7% (18,543 versus 15,253). Single-thread Passmark scores give the 7600X a 21.6% edge (4,135 versus 3,241).

Overall, the database records 13 wins for the 7600X and only 2 wins for the PRO 5655G. The average benchmark score tells a similar story at a high level: the PRO 5655G averages 28,032, while the 7600X averages 27,636. Despite the 7600X winning the majority of individual tests, the PRO 5655G's higher average score indicates that its Cinebench R23 wins carry significant weight in the aggregate. The PRO 5655G sits at the 80th percentile among all CPUs, while the 7600X is at the 79th percentile. The nearest rivals for the PRO 5655G include the AMD Ryzen 5 PRO 8500GE (0.1% lower average score), the Intel Core i9-12900H (0.1% higher), and the Intel Core i5-14500T (0.1% lower). The 7600X's nearest rivals include the AMD Ryzen 7 5700X and Intel Core i5-12600K, both with average scores 0.2% higher, and the AMD Ryzen 7 5800 at 0.4% higher.

The Verdict

The data supports a straightforward choice for most builders. The AMD Ryzen 5 7600X is the superior processor for general performance. It wins 13 of the 15 head-to-head benchmarks, and its wins include the most heavily weighted tests in the Passmark suite. If you are building a system for gaming, content creation, or any workload that relies on raw compute throughput, the 7600X is the pick. Its single-thread Passmark score of 4,135 is substantially higher, and its multithread score of 28,390 is far beyond what the PRO 5655G can manage.

The AMD Ryzen 5 PRO 5655G should only be considered by a niche audience. Its two wins are both in Cinebench R23, which is a rendering benchmark. If your primary application is 3D rendering using the Cinebench R23 engine, the PRO 5655G delivers 13.2% higher multi-core performance and 23.9% higher single-core performance. That is a real advantage for that specific task. However, the 7600X wins Cinebench R15 by 30.9% multi-core and 22% single-core, so the PRO 5655G's advantage is not consistent across all Cinebench versions.

The PRO 5655G also has a practical platform advantage: it uses DDR4 memory and the AM4 socket, which are older and more widely available. The 7600X requires DDR5 and the AM5 socket. Builders with existing DDR4 memory or AM4 motherboards may find the PRO 5655G a more convenient upgrade path. However, the benchmark data does not support choosing the PRO 5655G for any performance reason outside of Cinebench R23. The 7600X is the faster chip in nearly every measurable way.

Specification Differences

The two processors differ significantly in their memory and platform support, which dictates motherboard choice. The PRO 5655G uses the AMD Socket AM4 and supports DDR4 memory with a dual-channel bus and a bandwidth of 51.2 GB/s. The 7600X uses the AMD Socket AM5 and supports DDR5 memory with a dual-channel bus and a bandwidth of 83.2 GB/s. This represents a 32 GB/s advantage for the 7600X in theoretical memory bandwidth.

Clock speeds also differ substantially. The PRO 5655G has a base clock of 3.90 GHz and a boost clock of 4.40 GHz. The 7600X has a base clock of 4.70 GHz and a boost clock of 5.30 GHz. The 7600X is therefore 0.80 GHz higher at base and 0.90 GHz higher at boost. The thermal design power (TDP) reflects these higher clocks: the 7600X is rated at 105 watts, while the PRO 5655G is rated at 65 watts.

PCIe support is another differentiating factor. The PRO 5655G offers PCIe Gen 3 with 16 lanes (CPU only). The 7600X offers PCIe Gen 5 with 24 lanes (CPU only). The 7600X also has an unlocked multiplier, while the PRO 5655G's multiplier is locked. The integrated graphics differ as well: the PRO 5655G has Radeon Vega 7, while the 7600X has Radeon Graphics. Both processors support ECC memory. The PRO 5655G was released on 2024-05-06, while the 7600X was released on 2022-09-26. The 7600X has a launch MSRP of $299. The PRO 5655G has no recorded launch MSRP.

Architecture Differences

The architectural gap between these two CPUs is significant and explains the performance differences. The PRO 5655G is built on the Zen 3 architecture, codenamed Cezanne, and is part of the 5000 series. It uses a 7 nm process node from TSMC and has 10,700 million transistors on a die size of 180 mm². The 7600X is built on the Zen 4 architecture, codenamed Raphael, and is part of the 7000 series. It uses a 5 nm process node from TSMC and has 6,570 million transistors on a die size of 71 mm². The smaller 5 nm node with fewer transistors allows for higher clock speeds at a higher TDP.

Cache configurations also differ. Both have 64 KB of L1 cache per core and 512 KB of L2 cache per core for the PRO 5655G. The 7600X has 1 MB of L2 cache per core, double the amount. The L3 cache is 16 MB for the PRO 5655G, while the 7600X has 32 MB of shared L3 cache. This doubled L2 and L3 capacity is a major factor in the 7600X's superior Passmark performance, particularly in tests like data compression and integer math.

The generations are distinct: the PRO 5655G is listed as "Ryzen 5 (Zen 3 (Cezanne))" and the 7600X as "Ryzen 5 (Zen 4 (Raphael))". The 7600X also benefits from a newer process node and a more efficient transistor layout per square millimeter, despite having fewer total transistors. The PRO 5655G's larger die and higher transistor count are due to the integrated Radeon Vega 7 graphics, which occupy significant silicon area.

Where Each One Wins

The AMD Ryzen 5 7600X wins in the vast majority of workloads. It is the clear choice for any task that stresses raw compute throughput. Its wins in Passmark integer math (84,749 versus 67,561) and floating point math (51,025 versus 38,649) make it better for scientific computing, financial modeling, and any number-crunching application. The physics test win (1,824 versus 686) indicates better performance in simulation and game physics. Data compression and encryption wins (317,862 versus 255,608 and 18,543 versus 15,253) make it faster for file archiving and secure data handling. The multithread score (28,390 versus 19,129) and the single-thread score (4,135 versus 3,241) confirm it as the superior all-around performer for productivity and gaming.

The AMD Ryzen 5 PRO 5655G wins only in Cinebench R23, both multi-core and single-core. This makes it a specialized tool for 3D rendering workloads that use the Cinema 4D render engine. The 13.2% multi-core and 23.9% single-core advantages are substantial for that specific application. If a user's primary workflow is rendering in a Cinebench R23-compatible application, the PRO 5655G offers measurable benefits. Additionally, its lower TDP of 65 watts and support for DDR4 memory make it a more power-efficient and potentially simpler build for users who already own AM4 motherboards and DDR4 RAM, though the database does not record any performance advantage for the PRO 5655G in other memory-sensitive or power-sensitive benchmarks. For all other measured workloads, the 7600X is the definitive winner.
