AMD Ryzen 5 PRO 4655GE

The AMD Ryzen 5 PRO 4655GE is a 6-core, 12-thread desktop processor built on the Zen 2 architecture under the Renoir codename. It is manufactured by TSMC on a 7nm process with 9,800 million transistors on a 156 mm² die. The CPU runs at a 3.30 GHz base clock and a 4.20 GHz boost clock, with a 35W TDP. It integrates Radeon Vega 7 graphics, supports ECC memory, and uses the AMD Socket AM4 with dual-channel DDR4 memory. Released in 2022 and still in active production, the part targets the desktop segment with a locked multiplier. It lands in the 79th percentile of all CPUs in the database, with an average benchmark score of 20,900.

Benchmark Performance

The 4655GE's average benchmark score of 20,900 places it in the 79th percentile of all CPUs tested, meaning it outperforms the majority of the database. Its four nearest rivals are extraordinarily close, all within 0.3% of its aggregate score. The Intel Core i5-12500 averages 20,897, a 0% delta — a dead heat. The Intel Core i5-12600T averages 20,917, putting the 4655GE 0.1% behind. The AMD Ryzen 5 5500 scores 20,875, which the 4655GE edges by 0.1%. The AMD EPYC 7J13 scores 20,845, 0.3% behind the 4655GE.

In Cinebench R23, the 4655GE scores 12,045 multi-core and 1,700 single-core. The R20 run produces 5,058 multi-core and 714 single-core, while R15 yields 1,213 multi-core and 171 single-core. The consistency across all three Cinebench versions indicates stable, repeatable performance. The multi-core results scale as expected for a 6-core, 12-thread part, while the single-core scores reflect the 4.20 GHz boost clock.

Passmark results reinforce the picture. The multithread score is 14,171, and the single-thread score is 2,660. Integer math reaches 48,513, while floating-point math lands at 27,947. Data compression is a standout at 193,067, suggesting strong throughput in compression and archiving workloads. Data encryption scores 11,586, extended instructions 11,792, random string sorting 21,382, physics 592, and find prime numbers 28.

The narrow deltas against all four nearest rivals mean the 4655GE is effectively interchangeable with the i5-12500, i5-12600T, Ryzen 5 5500, and EPYC 7J13 in average aggregate performance. The 79th percentile placement confirms a solidly mid-to-upper-tier desktop CPU. For a 35W part, the 4655GE delivers performance that rivals much higher-power processors.

Power and Thermals

The 4655GE carries a 35W TDP, placing it firmly in the low-power class of desktop processors. This is a key differentiator: the 7nm TSMC process, with its 9,800 million transistors and 156 mm² die, enables high performance within a modest thermal envelope. The integrated Radeon Vega 7 graphics means the 35W budget covers both CPU and GPU workloads, so systems with no discrete graphics card still have a complete visual output solution.

A 35W TDP implies that a capable air cooler — even a compact or low-profile unit — is sufficient to maintain the 4.20 GHz boost clock under sustained loads. The locked multiplier prevents overclocking, so the 35W figure is effectively the ceiling for power draw. This predictability is valuable for system integrators and commercial deployments where thermal design is fixed. The low power draw also translates to reduced heat output, which simplifies chassis design and can enable quieter operation in office environments.

The 7nm process node and Renoir architecture are mature, and the active production status means the part remains available for new designs. The combination of a 35W TDP, integrated graphics, and ECC memory support makes the 4655GE a compelling choice for small-form-factor workstations, thin clients, and always-on systems where heat and power are at a premium.

Single-Thread vs Multi-Thread Behavior

The Cinebench R23 single-core score of 1,700 and multi-core score of 12,045 show a wide gap between lightly threaded and fully parallel workloads. The single-thread Passmark score of 2,660 indicates strong responsiveness for everyday tasks like web browsing, document editing, and light development work. The multi-thread Passmark score of 14,171, combined with the R23 multi-core result, demonstrates that the 12 threads scale effectively under parallel loads such as video encoding, compilation, and batch rendering.

The R15 single-core score of 171 versus multi-core 1,213, and the R20 single-core 714 versus multi-core 5,058, follow the same pattern. The consistent relationship across all three Cinebench versions suggests the Zen 2 architecture's thread scheduling and cache hierarchy are well balanced. The 8 MB shared L3 cache, 512 KB L2 per core, and 64 KB L1 per core provide a moderate cache topology that supports both single- and multi-threaded execution.

For real-world use, the single-thread scores matter for interface responsiveness and latency-sensitive applications, while the multi-thread scores matter for throughput-oriented tasks. The data compression score of 193,067 indicates strong performance in archiving and data movement workloads, while the integer math score of 48,513 shows robust general-purpose compute. The floating-point math score of 27,947 is respectable for a 35W part, and the extended instructions score of 11,792 indicates solid SIMD throughput for workloads that use modern instruction sets.

The dual-channel DDR4 memory bus with 51.2 GB/s bandwidth keeps both the CPU cores and the Radeon Vega 7 iGPU fed with data. ECC memory support adds a layer of data integrity that is rare in this performance class, making the 4655GE suitable for entry-level workstations and reliability-conscious deployments. The single-thread performance of 2,660 in Passmark is competitive for the 35W class, and the multi-thread result of 14,171 shows the 6-core design punches above its power class.

Platform and Compatibility

The 4655GE uses the AMD Socket AM4. Memory support is DDR4 in a dual-channel configuration, with a memory bandwidth of 51.2 GB/s. ECC memory is supported, which is unusual for a desktop-oriented part and adds appeal for professional and commercial systems.

PCIe is Gen 3 with 20 lanes from the CPU. The Gen 3 lanes are sufficient for most storage and graphics configurations, particularly in a 35W APU class. The integrated Radeon Vega 7 graphics removes the need for a discrete GPU in many office, media, and light-content-creation scenarios, while the 20 PCIe lanes remain available for users who want to add a dedicated graphics card or high-speed storage.

The locked multiplier means no overclocking, but the AM4 socket, active production status, and PRO branding indicate a long-lived, dependable platform. The part number 100-000001156100-100001156MPK and the PRO designation target commercial buyers who prioritize stability and support over enthusiast features. The 7nm process from TSMC is mature, and the 9,800 million transistors on a 156 mm² die represent a compact, efficient design.

The Renoir codename places the 4655GE in the Zen 2 generation, and the Radeon Vega 7 integrated graphics provide a complete visual solution without additional hardware. The 51.2 GB/s memory bandwidth is well matched to the Vega 7's needs, ensuring that both CPU and GPU workloads have adequate data throughput. The dual-channel DDR4 support is standard for the platform, and the ECC option widens the part's applicability.

How It Compares

Intel Core i5-12500: The i5-12500 averages 20,897, a 0% delta from the 4655GE. The two are statistically indistinguishable in aggregate performance. The 4655GE matches that score while carrying a 35W TDP and integrated Radeon Vega 7 graphics, making it a strong option for power-constrained systems that still need solid multi-threaded throughput.

Intel Core i5-12600T: The i5-12600T averages 20,917, 0.1% ahead of the 4655GE. The two are effectively tied, with the 4655GE offering integrated graphics and ECC memory support as differentiators. The 0.1% gap is well within run-to-run variance, so the choice between them comes down to platform and feature preferences.

AMD Ryzen 5 5500: The Ryzen 5 5500 averages 20,875, 0.1% behind the 4655GE. Both are 6-core, 12-thread parts, and the delta is negligible. The 4655GE's ECC memory support and Radeon Vega 7 graphics are notable features for its performance class, giving it an edge in commercial and workstation scenarios.

AMD EPYC 7J13: The EPYC 7J13 averages 20,845, 0.3% behind the 4655GE. This is a notable result, as the EPYC 7J13 is a different class of product, yet the 4655GE posts a higher average score. The 0.3% delta, while small, shows that a 35W desktop APU can keep pace with enterprise hardware in aggregate benchmarks, an impressive outcome for a low-power part.
