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

Where Each One Wins

The benchmark data is unambiguous: the Intel Core 9 273PE wins every recorded comparison. Across 17 head-to-head tests, the Intel part takes all 17, while the AMD Ryzen 5 PRO 5655GE records zero wins. That does not mean the AMD chip is without purpose, but it does mean the use-case split is defined by margins rather than by which processor takes a given category.

The AMD Ryzen 5 PRO 5655GE is a 6-core, 12-thread Zen 3 part aimed at a different performance class entirely. Its strongest relative showing comes in single-threaded PassMark work, where it trails the Intel part by only 11.2%. In the broader Cinebench suite, the Intel advantage sits consistently around 50%. The AMD chip's best absolute scores are in PassMark integer math (67582) and floating-point math (38204), but the Intel part more than doubles those figures in both cases.

The Intel Core 9 273PE dominates every workload category. Its most extreme wins come in PassMark physics (3120 versus 648, a 79.2% margin) and PassMark find prime numbers (203 versus 49, a 75.9% margin). These are heavily parallel workloads, and the Intel part's 12 cores and 24 threads simply outclass the AMD's 6 cores and 12 threads. The Intel chip also holds a commanding lead in memory bandwidth (89.6 GB/s versus 51.2 GB/s), which helps in data-heavy tasks like compression and encryption.

For a builder choosing between these two, the decision is not about workload type but about performance tier. The AMD part occupies the lower end of the desktop spectrum, while the Intel part sits near the top of the database's rankings. The Intel chip holds a 90th percentile vs all CPUs, while the AMD chip sits at the 78th percentile. The average benchmark score gap is massive: 49845 for Intel versus 25880 for AMD.

Architecture Differences

The two processors come from different manufacturing and design generations. The AMD Ryzen 5 PRO 5655GE uses Zen 3 architecture on the Cezanne codename, built on TSMC's 7 nm process. The Intel Core 9 273PE uses the Bartlett Lake codename on Intel's 10 nm process. Both are active production parts, and both are desktop market segments, but that is where the architectural similarities end.

The core layouts diverge sharply. AMD offers 6 cores and 12 threads, with 64 KB of L1 cache per core, 512 KB of L2 per core, and 16 MB of shared L3 cache. Intel offers 12 cores and 24 threads, with 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The transistor counts and die sizes for the Intel part are not recorded in the database, while the AMD chip lists 10,700 million transistors on a 180 mm² die.

Memory support also differs. The AMD chip supports DDR4 only, while the Intel chip supports both DDR4 and DDR5. Both use dual-channel memory buses, but the Intel part's maximum bandwidth is 89.6 GB/s versus 51.2 GB/s for AMD. Both support ECC memory, which matters for workstation-style reliability.

PCIe connectivity is another split. The AMD chip uses PCIe Gen 3 with 16 CPU lanes, while the Intel part uses PCIe Gen 5 with 16 CPU lanes. That is a significant generational jump for storage and GPU bandwidth. Integrated graphics differ as well: AMD uses Radeon Vega 7, Intel uses UHD Graphics 730.

The clock profiles are notable. The AMD chip has a base clock of 3.40 GHz and a boost of 4.40 GHz. The Intel chip has a lower base of 2.30 GHz but a much higher boost of 5.70 GHz. Both are locked multipliers, so neither offers overclocking headroom. Both carry a 65 W TDP, which keeps them in the same thermal envelope despite the Intel part's much higher performance.

Head-to-Head Benchmarks

The Cinebench results establish the overall shape of the comparison. In Cinebench R15 multicore, the Intel part scores 3153 against 1562, a 50.5% lead. In single-core R15, Intel leads 445 to 220, a 50.6% margin. R20 multicore shows 13140 versus 6511 (50.4% lead), and R20 single-core shows 1855 versus 918 (50.5% lead). R23 multicore gives 31288 versus 15504 (50.4% lead), and R23 single-core gives 4417 versus 2188 (50.5% lead). The consistency is striking: across all six Cinebench tests, the Intel advantage sits between 50.4% and 50.6%.

PassMark results show a wider range of margins. The smallest Intel win is in single-threaded tests: 3650 versus 3240, an 11.2% lead. That is the AMD chip's most competitive showing. The data compression test gives Intel a 43.8% lead (405885 versus 228037). Data encryption shows a 36.1% lead (22719 versus 14509). Extended instructions show a 36.2% lead (24630 versus 15714). Random string sorting gives Intel a 47.3% lead (45098 versus 23769).

The largest gaps appear in heavily parallel and math-heavy workloads. PassMark integer math gives Intel a 51.5% lead (139410 versus 67582). PassMark multithread gives a 50.9% lead (36810 versus 18057). Floating-point math shows a 64.6% lead (107884 versus 38204). Find prime numbers gives Intel a 75.9% lead (203 versus 49). Physics shows the widest gap at 79.2% (3120 versus 648).

The pattern is clear: the AMD chip is closest in single-threaded integer work, and the Intel chip's advantage grows as workloads scale across cores and use more complex instruction paths. The Intel part's 36 MB of shared L3 cache and per-core 2 MB L2 likely contribute to its dominance in compression and encryption tasks, where data locality matters.

Specification Differences

The two processors differ in nearly every measurable specification. Core count: 6 versus 12. Thread count: 12 versus 24. Base clock: 3.40 GHz versus 2.30 GHz. Boost clock: 4.40 GHz versus 5.70 GHz. Both are 65 W TDP parts, but the sockets are incompatible: AMD Socket AM4 versus Intel Socket 1700.

Cache configurations diverge completely. AMD uses 64 KB L1 per core, 512 KB L2 per core, and 16 MB shared L3. Intel uses 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Intel part has more than double the L3 capacity and four times the per-core L2.

Memory support: AMD is DDR4 only, Intel is DDR4 and DDR5. Both are dual-channel, but Intel's bandwidth is 89.6 GB/s versus AMD's 51.2 GB/s. Both support ECC. PCIe: AMD is Gen 3 with 16 lanes, Intel is Gen 5 with 16 lanes. Integrated graphics: Radeon Vega 7 versus UHD Graphics 730.

Process node: 7 nm TSMC for AMD, 10 nm Intel for Intel. Foundry: TSMC versus Intel.

The Verdict

The data supports a straightforward conclusion. The Intel Core 9 273PE is the faster processor in every measured test, and by large margins in most of them. For workloads that scale across cores, such as rendering, physics simulation, and prime number computation, the Intel part is roughly two to four times faster depending on the test. The Cinebench suite shows a consistent 50% advantage across both single-core and multi-core runs, which indicates the Intel architecture holds a per-thread efficiency lead as well as a core-count advantage.

The AMD Ryzen 5 PRO 5655GE is not without merit, but its strengths are relative rather than absolute. Its closest result is the 11.2% gap in PassMark single-threaded performance, which suggests it handles lightly threaded integer tasks reasonably well. Its 65 W TDP matches the Intel part, and its DDR4 support may be simpler for existing AM4 platform users. However, the Intel part also supports DDR4, so that is not a differentiating advantage. The AMD chip's PCIe Gen 3 interface is a generation behind Intel's PCIe Gen 5, which matters for users planning high-bandwidth storage or current GPUs.

For a builder with an existing AM4 motherboard, the Ryzen 5 PRO 5655GE offers a competent 6-core upgrade path within that socket. For a new build, the Intel Core 9 273PE delivers dramatically more performance across every workload category in the database, with double the core count, more than double the L3 cache, higher memory bandwidth, and a newer PCIe generation. The Intel part's launch MSRP is $549, and its nearest rivals in the database are all within roughly 1% of its average score, which places it in a competitive tier near the top of the desktop market.

The choice comes down to platform commitment versus performance ceiling. The AMD chip is a reasonable option for those already on Socket AM4 who do not need maximum throughput. The Intel chip is the clear choice for anyone prioritizing raw performance, parallel workloads, or future-facing connectivity. The recorded data shows no workload where the AMD part wins, so the verdict is straightforward: the Intel Core 9 273PE is the superior processor by every benchmark measurement in the database.
