Architecture Differences

The AMD Ryzen 5 PRO 5655GE and Intel Core 3 305 represent two fundamentally different design philosophies. The AMD part uses the Zen 3 architecture under the Cezanne codename, built on a 7 nm process at TSMC with 10,700 million transistors on a 180 mm² die. The Intel Core 3 305 uses the Wildcat Lake codename with a 3 nm process at Intel, though the database records no transistor count or die size for this part.

Core and thread counts differ significantly. Both processors have 6 physical cores, but the AMD Ryzen 5 PRO 5655GE supports 12 threads through simultaneous multithreading, while the Intel Core 3 305 has 6 threads with no SMT capability. This explains much of the multi-threaded performance gap.

Cache hierarchies are structured differently. The AMD part allocates 64 KB of L1 cache per core, 512 KB of L2 per core, and a 16 MB L3 pool. The Intel part uses 192 KB of L1 total, 2.5 MB of L2, and 6 MB of shared L3. The larger L3 on the AMD chip provides a substantial capacity advantage for working sets that fit in cache.

Clock speeds also diverge. The AMD Ryzen 5 PRO 5655GE runs at a 3.40 GHz base clock and boosts to 4.40 GHz. The Intel Core 3 305 has a much lower 1.50 GHz base clock but boosts to 4.30 GHz. The wide gap between base and boost on the Intel part suggests a design tuned for burst workloads and power efficiency rather than sustained throughput.

The memory subsystems point to different target platforms. The AMD processor uses DDR4 with dual-channel access and 51.2 GB/s bandwidth, plus ECC support. The Intel processor uses DDR5 and LPDDR5X with single-channel access but higher bandwidth at 59.7 GB/s. The Intel part lacks ECC memory support.

PCIe connectivity differs as well. The AMD Ryzen 5 PRO 5655GE provides PCIe Gen 3 with 16 lanes from the CPU. The Intel Core 3 305 provides PCIe Gen 4 with only 6 lanes. The AMD part offers more expansion lanes, while the Intel part offers a newer standard with fewer lanes.

The integrated graphics also differ. The AMD chip includes Radeon Vega 7 graphics, while the Intel chip includes Intel Xe3 Graphics with 1 Xe core. The database records no direct graphics benchmark comparison for these two iGPUs.

The AMD processor uses the AMD Socket AM4 platform, while the Intel processor uses Intel BGA 1516, a soldered mobile package. The market segments reflect this: the AMD part is listed as Desktop, while the Intel part is listed as Mobile.

Head-to-Head Benchmarks

The AMD Ryzen 5 PRO 5655GE dominates the Cinebench suite across the board. In Cinebench R15 multi-core, the AMD part scores 1562 versus 1322, a lead of 18.2%. Single-core R15 shows a similar 18.3% advantage with 220 versus 186. The R20 tests show 6511 versus 5511 for multi-core (18.1%) and 918 versus 777 for single-core (18.1%). Cinebench R23 follows the same pattern: 15504 versus 13123 in multi-core and 2188 versus 1852 in single-core, both at 18.1% deltas.

The PassMark suite reveals a more nuanced picture. The AMD processor wins 8 of the 12 PassMark tests, with particularly large margins in integer math and data compression. Integer math shows the biggest gap in the entire comparison: the AMD chip scores 67582 against 32295 for the Intel part, a 109.3% advantage. Data compression also skews heavily toward AMD at 228037 versus 146857, a 55.3% delta. Data encryption favors AMD by 31.7% (14509 versus 11019). Random string sorting goes to AMD by 34.9% (23769 versus 17623). Extended instructions show a narrower 16% edge for AMD (15714 versus 13543). PassMark multithread favors AMD by 17% (18057 versus 15439).

The Intel Core 3 305 counters with wins in five tests, some by wide margins. The largest is in find prime numbers, where Intel scores 115 versus 49 for AMD, a 57.4% lead in the opposite direction. Physics shows Intel ahead at 1233 versus 648, a 47.4% margin. The single-thread tests show Intel at 3977 versus 3240, an 18.5% advantage. Floating point math goes to Intel by 9.6% (42284 versus 38204).

The overall win count stands at 12 for the AMD Ryzen 5 PRO 5655GE and 5 for the Intel Core 3 305. The AMD processor wins all six Cinebench tests and six of the eleven PassMark tests. The Intel processor wins the remaining five PassMark tests.

The thread count difference, cache capacity difference, and memory channel difference are the most impactful specification gaps. The TDP difference between 65 W and 15 W indicates very different power envelopes, though the database records no power consumption measurements beyond these TDP figures.

The Verdict

Benchmark results indicate that the AMD Ryzen 5 PRO 5655GE is the stronger overall performer. It holds a 41.4% higher average benchmark score (25880 versus 18302) and wins 12 of 17 head-to-head tests. The AMD part also ranks higher in the overall percentile distribution at 78 versus 72.

The Intel Core 3 305 does not match the AMD chip in most multi-threaded workloads. The thread advantage of the AMD part (12 versus 6) shows up clearly in Cinebench multi-core tests and in PassMark multithread. The 109.3% lead in integer math and 55.3% lead in data compression demonstrate that the AMD processor is substantially faster for compute-heavy and data-processing tasks.

However, the Intel Core 3 305 delivers a decisive single-thread performance win. The 18.5% advantage in PassMark single thread (3977 versus 3240) is the largest single-thread gap in this comparison. The Intel part also wins physics simulation by 47.4% and prime number finding by 57.4%. These results indicate a different strength profile: the Intel chip is efficient at specific instruction patterns and single-thread workloads.

The platform differences matter for deployment decisions. The AMD part uses socket AM4 with DDR4 and dual-channel memory, 16 PCIe Gen 3 lanes, and ECC support. The Intel part uses BGA 1516 with DDR5/LPDDR5X single-channel memory, 6 PCIe Gen 4 lanes, and no ECC. The Intel part is a mobile processor with 15 W TDP, while the AMD part is a desktop processor with 65 W TDP.

For desktop workstations requiring sustained multi-threaded throughput and ECC memory, the data points clearly to the AMD Ryzen 5 PRO 5655GE. For mobile or power-constrained systems where single-thread speed and a newer process node matter more, the Intel Core 3 305 has identifiable strengths.

Where Each One Wins

The AMD Ryzen 5 PRO 5655GE wins across the entire Cinebench suite, covering both multi-core and single-core rendering workloads. The 18.1% to 18.3% margins are consistent across all three Cinebench versions. This makes the AMD processor the pick for rendering tasks that use Cinebench-style workloads.

In PassMark tests, the AMD chip wins integer math by 109.3%, data compression by 55.3%, random string sorting by 34.9%, data encryption by 31.7%, extended instructions by 16%, and multithread by 17%. These are the workloads where the 12 threads and larger cache configuration deliver measurable advantages. The 16 MB L3 cache versus 6 MB likely contributes to the compression and sorting wins.

The Intel Core 3 305 wins PassMark single thread by 18.5%, which is notable given that the AMD chip has a higher boost clock (4.40 GHz versus 4.30 GHz). The Intel part also wins floating point math by 9.6%, physics by 47.4%, and find prime numbers by 57.4%. These wins suggest the Intel architecture handles certain math patterns and physics calculations more efficiently despite having fewer threads.

The Intel processor also holds advantages in platform-level specifications. It uses a 3 nm process versus 7 nm, supports DDR5 and LPDDR5X memory, offers PCIe Gen 4, and fits a 15 W TDP envelope. The memory bandwidth is higher at 59.7 GB/s despite single-channel access.

The AMD processor counters with ECC memory support, dual-channel DDR4, 16 PCIe Gen 3 lanes, and a desktop socket platform. The 10,700 million transistors on a 180 mm² die provide a material advantage in total cache capacity and thread count.

For workloads that stress sustained multi-threaded integer operations, data compression, encryption, or rendering, the AMD Ryzen 5 PRO 5655GE is the stronger choice based on the benchmark data. For workloads dominated by single-thread performance, prime number computation, physics simulation, or floating point math, the Intel Core 3 305 shows clear wins. The overall score distribution favors AMD, but the Intel part occupies a distinct performance niche that its benchmarks confirm.
