AMD Ryzen 3 PRO 5355G vs Intel Core 7 251E Comparison

Where Each One Wins

The AMD Ryzen 3 PRO 5355G and the Intel Core 7 251E occupy very different positions in the desktop processor landscape. The AMD part is a four-core, eight-thread Zen 3 design built for efficiency and solid single-threaded responsiveness. The Intel part is a 24-core, 32-thread powerhouse aimed at heavy parallel workloads. The recorded data shows no direct head-to-head benchmark wins for either processor because the head-to-head matrix is empty. However, the individual benchmark scores for the AMD processor and the architectural specifications for the Intel processor allow a clear use-case split.

The AMD Ryzen 3 PRO 5355G delivers a PassMark single-thread score of 3096, which is strong for a 4.00 GHz base and 4.20 GHz boost clock. That places it in the 79th percentile among all CPUs in the database. For everyday desktop tasks, lightly threaded applications, and workloads that depend on per-core speed, the AMD part holds the advantage. Its 65 TDP and 7 nm TSMC process also indicate efficient operation, which suits compact desktop builds.

The Intel Core 7 251E, by contrast, has no recorded benchmark scores in the database. Its advantage is entirely structural: 24 cores, 32 threads, a 5.60 GHz boost clock, 36 MB of shared L3 cache, and 89.6 GB/s of memory bandwidth. These specifications target multi-threaded rendering, compilation, virtualization, and content creation where core count and memory throughput dominate. The Intel part also supports both DDR4 and DDR5 memory, while the AMD part is limited to DDR4.

The AMD processor wins in situations where clock speed and per-core efficiency matter. The Intel processor wins in situations where the workload can scale across many threads. The data shows no overlap in their intended strengths.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the Intel Core 7 251E has an empty benchmark array. The only quantitative comparisons available come from the AMD processor's individual PassMark scores and its nearest rival list, plus the Intel part's specifications.

The AMD Ryzen 3 PRO 5355G achieves an average benchmark score of 27382. Its nearest rivals in the database are the Intel Core i7-13700H at 27355 (0.1% faster), the Intel Core Ultra 5 125H at 27507 (0.5% faster), the AMD Ryzen 7 5800 at 27535 (0.6% faster), and the Intel Core i5-12600K at 27578 (0.7% faster). This places the AMD part within 0.7% of those four processors, indicating that its overall performance profile is competitive with much higher-core-count parts in the database's average scoring.

Looking at individual workloads, the AMD Ryzen 3 PRO 5355G scores 168041 in data compression, 10288 in data encryption, 11935 in extended instructions, 36 in find prime numbers, 25245 in floating point math, 45910 in integer math, 14033 in multithread, 701 in physics, and 18819 in random string sorting. The multithread score of 14033 is modest compared to what a 24-core processor would be expected to produce, but without a recorded score for the Intel part, no direct delta can be stated.

The Intel Core 7 251E has no measurable benchmark data. Its 24 cores and 32 threads, combined with 5.60 GHz boost and 36 MB of shared L3 cache, suggest it would outperform the AMD part in parallel workloads, but the database does not quantify that advantage. The AMD part's single-thread score of 3096 is the only recorded single-thread data point in this comparison.

Specification Differences

The two processors differ substantially across nearly every specification field. The AMD Ryzen 3 PRO 5355G uses 4 cores and 8 threads, while the Intel Core 7 251E uses 24 cores and 32 threads. Base clocks differ: 4.00 GHz for the AMD part versus 2.10 GHz for the Intel part. Boost clocks differ: 4.20 GHz for the AMD part versus 5.60 GHz for the Intel part.

Both processors share a 65 TDP, which is notable given the Intel part's much higher core count. The AMD part uses a 7 nm TSMC process with 10,700 million transistors on a 180 mm² die. The Intel part uses a 10 nm Intel process on a 257 mm² die, with no transistor count recorded.

Cache configurations differ significantly. The AMD Ryzen 3 PRO 5355G has 64 KB L1 per core, 512 KB L2 per core, and 8 MB L3. The Intel Core 7 251E has 80 KB L1 per core, 2 MB L2 per core, and 36 MB shared L3. The Intel part has over four times the L3 cache.

Memory support diverges: the AMD part supports only DDR4, while the Intel part supports both DDR4 and DDR5. Memory bandwidth is 51.2 GB/s for the AMD part and 89.6 GB/s for the Intel part. Both support ECC memory and dual-channel memory buses.

PCIe capabilities differ. The AMD Ryzen 3 PRO 5355G uses PCIe Gen 3 with 16 lanes (CPU only). The Intel Core 7 251E uses PCIe Gen 5 with 16 lanes (CPU only). The Intel part offers significantly newer PCIe generation.

Integrated graphics differ: Radeon Vega 6 on the AMD part, UHD Graphics 770 on the Intel part. Sockets differ: AMD Socket AM4 for the AMD part, Intel Socket 1700 for the Intel part. Release dates differ: September 2024 for the AMD part, January 2025 for the Intel part. The Intel part has a launch MSRP of $384; the AMD part has no recorded launch MSRP.

Architecture Differences

The AMD Ryzen 3 PRO 5355G is built on Zen 3 architecture with the Cezanne codename, part of the Ryzen 3 generation. It uses a 7 nm process from TSMC with 10,700 million transistors. The Intel Core 7 251E uses the Bartlett Lake codename, part of the Core 7 generation, on a 10 nm Intel process. The AMD part's smaller process node indicates a more advanced manufacturing technology for its time.

The AMD processor's cache hierarchy uses 64 KB L1 per core and 512 KB L2 per core, which is typical for Zen 3. The Intel processor uses 80 KB L1 per core and 2 MB L2 per core, a larger per-core L2 allocation. The L3 cache difference is the most pronounced architectural gap: 8 MB on the AMD part versus 36 MB shared on the Intel part.

The Intel Core 7 251E supports both DDR4 and DDR5 memory, while the AMD Ryzen 3 PRO 5355G supports only DDR4. This gives the Intel part a memory bandwidth advantage of 89.6 GB/s versus 51.2 GB/s. The Intel part also uses PCIe Gen 5, which doubles the per-lane bandwidth compared to the AMD part's PCIe Gen 3.

Both processors support ECC memory, which is a relevant feature for workstation and server-adjacent workloads. Neither processor has an unlocked multiplier, so architectural differences are fixed at the factory. The Intel part's 24 cores and 32 threads represent a hybrid or high-core-count design, while the AMD part's 4 cores and 8 threads represent a traditional low-core-count desktop design.

The Verdict

The data supports a clear split. The AMD Ryzen 3 PRO 5355G should be selected for single-threaded and lightly threaded desktop workloads. Its 3096 single-thread score, 79th percentile ranking, and 4.20 GHz boost clock make it responsive for everyday tasks, and its 65 TDP with 7 nm process suggests efficient operation. Its average benchmark score of 27382 places it within 0.7% of processors like the Intel Core i5-12600K and AMD Ryzen 7 5800, confirming that core count alone does not determine overall usability.

The Intel Core 7 251E should be selected for heavily multi-threaded workloads. Its 24 cores, 32 threads, 5.60 GHz boost clock, 36 MB shared L3 cache, and 89.6 GB/s memory bandwidth provide the structural capacity for parallel processing that the AMD part cannot match. The DDR5 support and PCIe Gen 5 connectivity further position it for modern high-throughput systems. The recorded launch MSRP is $384.

Neither processor is unlocked for overclocking, and both run at 65 TDP. The AMD part offers a lower transistor count and smaller die, while the Intel part offers a larger die with no recorded transistor count. The AMD part arrived first in September 2024; the Intel part followed in January 2025.

For a compact desktop where per-core speed matters, the AMD Ryzen 3 PRO 5355G is the measured choice. For a workstation where core count and memory bandwidth drive performance, the Intel Core 7 251E is the specification-based choice. The database does not provide a direct benchmark comparison, so the decision rests on workload type.
