Architecture Differences

The AMD Ryzen 5 PRO 5655GE uses the Zen 3 architecture on the Cezanne codename, built on TSMC's 7 nm process. It integrates 10,700 million transistors on a 180 mm² die. The Intel Core Ultra 5 225T uses the Arrow Lake architecture (Arrow Lake-S codename) on TSMC's 3 nm process, integrating 17,800 million transistors on a 243 mm² die. The manufacturing node difference is substantial: 7 nm versus 3 nm, which contributes directly to the Intel part's efficiency and frequency behavior.

Core organization differs sharply. AMD's chip provides 6 cores with 12 threads via simultaneous multithreading. Intel's chip provides 10 physical cores with 10 threads and no multithreading. This means the Intel part relies on raw core count and higher boost clocks rather than thread duplication for its multi-threaded lead.

Cache hierarchies are not comparable in structure. The AMD part has 64 KB of L1 per core, 512 KB of L2 per core, and a 16 MB L3 cache. The Intel part has 192 KB of L1 per core, 3 MB of L2 per core, and a 20 MB shared L3 cache. The Intel L2 is six times larger per core, which helps with data locality in workloads that repeatedly access moderate-sized working sets.

Memory support diverges by generation. The AMD chip uses DDR4 with dual-channel memory and a maximum bandwidth of 51.2 GB/s. The Intel chip uses DDR5 with dual-channel memory and a maximum bandwidth of 102.4 GB/s, exactly double the AMD figure. This bandwidth advantage shows up in memory-sensitive algorithms and in the PassMark data compression and encryption results.

PCIe connectivity also differs. AMD provides PCIe Gen 3 with 16 lanes (CPU only). Intel provides PCIe Gen 5 with 20 lanes (CPU only), which doubles the per-lane bandwidth and adds four more lanes for expansion devices.

Integrated graphics are different as well. AMD uses Radeon Vega 7, while Intel uses Arc Xe-LPG Graphics with 16 execution units. Both are desktop parts with active production status, but neither has an unlocked multiplier. The AMD part uses the AMD Socket AM4, while the Intel part uses Intel Socket 1851.

The release dates differ by several months. The AMD Ryzen 5 PRO 5655GE launched on 2024-05-06, and the Intel Core Ultra 5 225T launched on 2024-12-31.

Head-to-Head Benchmarks

The Intel Core Ultra 5 225T wins 16 of the 17 head-to-head tests. The most decisive Intel victory is in PassMark prime number finding, where Intel scores 284 versus AMD's 49, a 82.7% advantage. This test is heavily dependent on integer throughput and branch handling, areas where the newer Arrow Lake core design excels.

In floating-point math, Intel's advantage is 53.8%. Intel scores 82751 against AMD's 38204. The physics test shows an even larger gap on a percentage basis: Intel scores 2053 versus 648, a 68.4% difference. This pattern suggests the Intel core's wider execution resources and higher boost clock of 4.90 GHz versus 4.40 GHz drive most of the compute-heavy wins.

Cinebench results are consistent across all three versions. In R15 multi-core, Intel scores 2214 versus 1562 (29.4% higher). In R20 multi-core, Intel scores 9227 versus 6511 (29.4% higher). In R23 multi-core, Intel scores 21971 versus 15504 (29.4% higher). Single-core Cinebench tests show nearly identical deltas: R15 single-core is 312 versus 220 (29.5% higher for Intel), R20 single-core is 1302 versus 918 (29.5% higher), and R23 single-core is 3101 versus 2188 (29.4% higher).

PassMark multithread shows Intel at 25358 versus AMD's 18057, a 28.8% gap. PassMark single-thread shows Intel at 4348 versus 3240, a 25.5% gap. These two tests bracket the general performance difference between the chips, with the multi-threaded gap slightly larger than the single-threaded gap.

Memory-related workloads favor Intel but by smaller margins. Data compression: Intel 233998 versus AMD 228037, only 2.5% apart. Random string sorting: Intel 28774 versus AMD 23769, a 17.4% gap. Data encryption: Intel 18289 versus AMD 14509, a 20.7% gap. Extended instructions: Intel 20083 versus AMD 15714, a 21.8% gap. The compression result is notable because the two chips are nearly equal despite Intel's memory bandwidth advantage, suggesting the workload is not bandwidth-limited at these sizes.

The AMD Ryzen 5 PRO 5655GE wins exactly one test: PassMark integer math. AMD scores 67582 against Intel's 59543, a 13.5% advantage. This is a counterintuitive result given Intel's higher core count, but it indicates that AMD's Zen 3 integer execution pipeline, combined with SMT, handles this particular workload more efficiently. The AMD chip also has a higher base clock of 3.40 GHz versus Intel's 2.50 GHz, which may contribute in lightly threaded integer loops.

The Verdict

The recorded data shows a clear overall performance leader in the Intel Core Ultra 5 225T. Its average benchmark score of 30468 is 17.7% above the AMD part's 25880, and it wins 16 of 17 head-to-head tests. The Intel chip's advantages are largest in compute-heavy integer and floating-point workloads, with prime number finding (82.7% lead), physics (68.4% lead), and floating-point math (53.8% lead) being the most lopsided results.

The Intel part's 10 physical cores and 4.90 GHz boost clock provide a strong foundation for multi-threaded throughput, as shown by its 21971 Cinebench R23 multi-core score versus the AMD's 15504. The 20 MB L3 cache and 3 MB per-core L2 cache, combined with DDR5 memory bandwidth of 102.4 GB/s, give it a structural edge in data-heavy tasks. The 3 nm process node and higher transistor count (17,800 million versus 10,700 million) support this performance within the same 65 W TDP envelope.

The AMD Ryzen 5 PRO 5655GE retains specific niches. Its 13.5% win in PassMark integer math shows that Zen 3's execution engine remains competitive in that targeted workload. The chip also supports ECC memory, which the Intel part does not, making it a candidate for systems that require error-correcting memory. Its lower base clock of 3.40 GHz versus Intel's 2.50 GHz is the only clock-speed specification where AMD leads, though Intel's boost clock of 4.90 GHz exceeds AMD's 4.40 GHz.

For buyers on the AMD Socket AM4 platform, the Ryzen 5 PRO 5655GE offers a familiar DDR4 ecosystem with active production status and ECC support. For those building on Intel Socket 1851, the Core Ultra 5 225T delivers substantially higher multi-core and single-core performance, double the memory bandwidth, PCIe Gen 5 connectivity, and a larger cache hierarchy. The data does not indicate any workload category, aside from integer math, where the AMD part is preferable on pure performance grounds.
