AMD Ryzen 5 PRO 5655GE vs Intel Core 9 273PTE Comparison

The AMD Ryzen 5 PRO 5655GE and the Intel Core 9 273PTE represent two very different approaches to desktop processing. The AMD chip is a 6-core, 12-thread part built on TSMC's 7 nm process with a 65 W TDP, while the Intel part is a 12-core, 24-thread processor on Intel's 10 nm process with a 45 W TDP. The data shows a clear overall winner in the Intel Core 9 273PTE, which takes 16 of the 17 head-to-head benchmark comparisons, but the AMD chip manages a narrow win in one specific workload.

Where Each One Wins

The Intel Core 9 273PTE dominates the broad majority of workloads. It wins every Cinebench iteration, both multi-core and single-core, across R15, R20, and R23. It also wins all PassMark tests except data encryption. The AMD Ryzen 5 PRO 5655GE takes only one head-to-head victory: PassMark data encryption, with a score of 14509 versus 14253 for the Intel part, a margin of 1.8%. This makes the AMD chip the pick for encryption-heavy tasks, but that is the extent of its advantage.

For multi-threaded productivity, the Intel part is decisively ahead. The Cinebench R23 multi-core score for the Intel is 20445 versus 15504 for AMD, a 24.2% gap. The PassMark multithread test shows a similar story: 24054 versus 18057, a 24.9% difference. For single-thread work, the Intel part also leads, though by a smaller margin. The Cinebench R23 single-core score is 2886 versus 2188, a 24.2% difference, and PassMark single-thread shows 3433 versus 3240, a 5.6% gap. The Intel part wins in physics simulation by a massive 66.2% margin (1917 versus 648), and in prime number finding by 65.5% (142 versus 49). These results indicate the Intel processor is the stronger choice for rendering, simulation, and general compute.

Architecture Differences

The two processors come from different manufacturing and design philosophies. The AMD Ryzen 5 PRO 5655GE uses the Zen 3 architecture, codenamed Cezanne, built on a 7 nm process at TSMC with a transistor count of 10,700 million and a die size of 180 mm². It has 6 cores and 12 threads. The Intel Core 9 273PTE uses the Bartlett Lake codename, built on Intel's 10 nm process. It has 12 cores and 24 threads, double the core and thread count of the AMD part.

Cache layouts differ substantially. The AMD chip has 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of L3 cache. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The larger per-core L2 and the much larger shared L3 give the Intel part a considerable cache advantage. Memory support also differs: the AMD chip supports DDR4 only, while the Intel part supports both DDR4 and DDR5, with a dual-channel memory bus. The recorded memory bandwidth is 51.2 GB/s for the AMD and 89.6 GB/s for the Intel, a 75% higher figure for the Intel part.

PCIe generation differs as well. The AMD chip uses Gen 3 with 16 lanes from the CPU, while the Intel part uses Gen 5 with 16 lanes. Both support ECC memory. Integrated graphics differ: the AMD has Radeon Vega 7, while the Intel has UHD Graphics 730. The AMD chip uses AMD Socket AM4, while the Intel uses Intel Socket 1700, so they are not interchangeable in any board. The Intel part has a launch MSRP of $549.

Head-to-Head Benchmarks

The Cinebench results show a consistent pattern. In Cinebench R15 multi-core, the Intel scores 2060 versus 1562 for AMD, a 24.2% difference. The R15 single-core test shows 290 versus 220, a 24.1% gap. Cinebench R20 multi-core gives 8586 versus 6511, again 24.2%, and R20 single-core gives 1212 versus 918, a 24.3% difference. Cinebench R23 multi-core shows 20445 versus 15504, 24.2%, and R23 single-core shows 2886 versus 2188, 24.2%. The margins are nearly identical across all Cinebench versions, indicating a consistent architectural advantage for the Intel part.

PassMark results show a wider range of deltas. The largest Intel win is in physics, where it scores 1917 versus 648, a 66.2% advantage. The find prime numbers test shows 142 versus 49, a 65.5% gap. Floating point math gives 60673 versus 38204, a 37% difference. Integer math gives 82411 versus 67582, an 18% difference. Random string sorting shows 28973 versus 23769, also 18%. Data compression gives 258704 versus 228037, an 11.9% gap. Extended instructions show 15952 versus 15714, a narrow 1.5% edge for Intel. The only AMD win is data encryption at 14509 versus 14253, a 1.8% margin.

The single-thread PassMark result is notable for being the smallest Intel win at 5.6% (3433 versus 3240). This suggests that while the Intel part has a strong single-core advantage in Cinebench, the PassMark single-thread test compresses that difference considerably. The Intel part still wins, but the AMD chip is closer in that specific metric.

The Verdict

The benchmark data points to a clear performance hierarchy. The Intel Core 9 273PTE wins 16 of 17 head-to-head tests, with an average benchmark score of 31143 versus 25880 for the AMD Ryzen 5 PRO 5655GE. The Intel part sits at the 82nd percentile of all CPUs, while the AMD sits at the 78th. The Intel part is 24% ahead in every Cinebench multi-core test and also 24% ahead in single-core Cinebench, which indicates a consistent per-thread advantage. The PassMark data shows the Intel part is particularly strong in physics and prime number finding, where it leads by over 65%.

The AMD Ryzen 5 PRO 5655GE is not without a role. Its 1.8% win in data encryption is a real, recorded advantage. It also runs at a 65 W TDP versus the Intel's 45 W, so the Intel part actually uses less power despite delivering higher performance. The AMD chip uses the AM4 socket, which may be relevant for users with existing boards, and it has a smaller cache footprint with 16 MB L3 versus 36 MB. The Intel part doubles the core count, offers DDR5 support, and delivers roughly 75% more memory bandwidth.

For workloads that depend on multi-core rendering, physics simulation, or heavy integer and floating point math, the Intel Core 9 273PTE is the stronger processor by a wide margin. For tasks that involve data encryption, the AMD Ryzen 5 PRO 5655GE holds a narrow edge, and it remains a viable option for AM4-based systems. The recorded data does not support any other AMD advantage. The Intel part is the superior choice for general compute, with the AMD chip limited to a single specific workload win.
