AMD Ryzen 5 5600 vs AMD Ryzen 5 PRO 4655GE Comparison

The AMD Ryzen 5 PRO 4655GE and AMD Ryzen 5 5600 are both six-core, twelve-thread AM4 processors, but they target very different priorities. The data shows a clear performance hierarchy, yet the PRO 4655GE retains a unique advantage that the 5600 cannot match. The verdict comes down to whether raw compute or integrated graphics and efficiency matter more for your specific build.

The Verdict

The AMD Ryzen 5 5600 is the outright performance winner in every single benchmark recorded. Out of 17 head-to-head tests, the 5600 wins all 17. Its most decisive victory is in PassMark find prime numbers, where it scores 137 against the PRO 4655GE’s 28, a massive 79.6% lead. This is not a close contest; the 5600 is simply the faster processor for CPU-bound work. If your priority is maximum multi-core and single-core throughput, the 5600 is the only choice between these two.

However, the PRO 4655GE is not without purpose. It is the only one of the two with integrated graphics, featuring Radeon Vega 7. This makes it a practical option for a system that will never see a discrete GPU, such as a basic office machine or a home theater PC. It also operates at a 35W TDP, which is substantially lower than the 5600’s 65W TDP, making it far easier to cool in a compact or silent build. The 5600’s performance lead is significant, but the PRO 4655GE wins on platform simplicity and power efficiency. The 5600 is for builders who will pair it with a dedicated graphics card; the PRO 4655GE is for those who will rely on the CPU alone.

Architecture Differences

The two processors represent different generations of AMD’s core designs. The PRO 4655GE is built on the Zen 2 architecture, codenamed Renoir, while the 5600 uses the newer Zen 3 architecture, codenamed Vermeer. Both are fabricated on a 7nm process at TSMC, but the similarities end there.

The transistor counts and die sizes tell a compelling story. The PRO 4655GE packs 9,800 million transistors on a 156 mm² die, while the 5600 uses 4,150 million transistors on a much smaller 74 mm² die. The Renoir chip is a monolithic design that includes the integrated graphics, which explains its larger physical footprint. The Vermeer chip is a chiplet design focused purely on CPU cores, allowing for a more concentrated and efficient layout.

Cache configuration is another major differentiator. Both have 64 KB of L1 cache per core and 512 KB of L2 cache per core. The crucial difference lies in L3 cache: the PRO 4655GE has 8 MB shared, while the 5600 has 32 MB shared. This fourfold increase in L3 cache is a primary reason for the 5600’s superior performance in many workloads, as it can hold more frequently used data closer to the cores.

Memory support is identical on paper: both support DDR4 in dual-channel mode with a memory bandwidth of 51.2 GB/s and both support ECC memory. The PCIe interface differs, with the PRO 4655GE offering Gen 3 with 20 lanes (CPU only), while the 5600 offers Gen 4 with 20 lanes (CPU only). The 5600’s newer PCIe standard doubles the bandwidth available for fast NVMe storage and modern GPUs.

Head-to-Head Benchmarks

The benchmark results paint a consistent picture of the 5600’s dominance. Across all Cinebench versions, the 5600 holds a near-uniform 34.2% lead. In Cinebench R23 multi-core, the 5600 scores 18,309 versus 12,045, and in single-core it scores 2,584 versus 1,700. The same margin appears in Cinebench R20 and R15, indicating a fundamental architectural advantage per clock and with multi-threaded scaling.

PassMark results show the 5600 winning across the board, but with varying margins. The largest gap is in find prime numbers, where the 5600’s score of 137 is 79.6% higher than the PRO 4655GE’s 28. This test is highly sensitive to cache and core efficiency, and the 5600’s larger L3 cache shines here. In floating point math, the 5600 scores 38,778 against 27,947, a 27.9% lead. Integer math shows a 29.1% advantage (68,396 vs 48,513). Data compression is closer, with the 5600 at 251,687 versus 193,067, a 23.3% lead. Random string sorting shows the smallest gap at 17.6% (25,943 vs 21,382).

The 5600 also dominates in PassMark physics, scoring 1,285 compared to 592, a 53.9% advantage. This test is a strong indicator of gaming performance potential. In single-threaded tests, the 5600 scores 3,256 versus 2,660, an 18.3% lead. The head-to-head data is exhaustive, and there is no benchmark where the PRO 4655GE comes out ahead. The 5600’s advantage is consistent, ranging from 17.6% to 79.6% depending on the workload.

Where Each One Wins

The AMD Ryzen 5 5600 wins in every compute-focused scenario. Its 34.2% lead in Cinebench multi-core tests makes it the superior choice for video rendering, 3D modeling, software compilation, and any heavily threaded productivity task. The 53.9% lead in PassMark physics suggests it will provide a better gaming experience when paired with a discrete GPU. The 18.3% lead in single-threaded tests also benefits everyday responsiveness and lightly threaded applications. For any builder who plans to install a graphics card, the 5600 is the clear winner.

The AMD Ryzen 5 PRO 4655GE wins in scenarios where a discrete GPU is not an option. Its integrated Radeon Vega 7 graphics make it a functional, complete platform on its own. This is ideal for a compact office PC, a media server, or a home theater PC where low noise and heat are priorities. Its 35W TDP is a major advantage in these builds, requiring less robust cooling and drawing less power under load. The PRO 4655GE also offers a lower overall platform cost for basic tasks, but the database does not record a launch MSRP for it, while the 5600 is recorded at a launch MSRP of $199. If the use case demands no discrete GPU and maximum efficiency, the PRO 4655GE is the practical pick despite its large performance deficit.
