AMD Ryzen 5 PRO 5655G vs Intel Core 7 251E Comparison

The AMD Ryzen 5 PRO 5655G and the Intel Core 7 251E are both 65 W desktop processors, yet they represent fundamentally different design philosophies. The Ryzen relies on a mature 7 nm Zen 3 architecture with six cores, while the Intel part uses a 10 nm process with 24 cores and a much higher boost clock. The database contains a full benchmark suite for the AMD processor, but the Intel chip currently has no recorded benchmark scores, an average score of zero, and no rival comparison data. This creates an unusual analytical situation: the AMD part has measurable performance data, while the Intel part can only be evaluated on its architectural specifications and market positioning.

Where Each One Wins

The AMD Ryzen 5 PRO 5655G wins in every measurable benchmark category because it is the only processor in this comparison with recorded performance data. Its benchmark suite includes Cinebench R15, R20, and R23 tests for both multi-core and single-core performance, plus a full Passmark workload set. In Cinebench R23, the AMD chip records a multi-core score of 17249 and a single-core score of 2435. In Cinebench R20, the scores are 7244 multi-core and 1022 single-core, while Cinebench R15 shows 1738 multi-core and 245 single-core. These numbers place the Ryzen 5 PRO 5655G in the 80th percentile among all CPUs in the database, with an average benchmark score of 28032.

The nearest rivals in the database provide context for where the AMD chip sits. Its average score of 28032 is nearly identical to the AMD Ryzen 5 PRO 8500GE, which scores 28054, a difference of only 0.1%. The Intel Core i9-12900H scores 28003, also 0.1% away, and the Intel Core i5-14500T scores 28065, again 0.1% away. The AMD Ryzen AI 5 435 scores 28128, which is 0.3% higher. This grouping suggests the Ryzen 5 PRO 5655G sits in a tight performance cluster, with no single rival more than 0.3% ahead or behind in average score.

For the Intel Core 7 251E, the database records no wins because there are no benchmark entries. Its percentile rank of 50 reflects the median position of an unmeasured part, not a tested result. The Intel chip does hold advantages in several specification fields: it has 24 cores versus 6, 32 threads versus 12, a boost clock of 5.60 GHz versus 4.40 GHz, and a larger L3 cache of 36 MB shared versus 16 MB. The Intel part also supports DDR5 memory in addition to DDR4, has a memory bandwidth of 89.6 GB/s versus 51.2 GB/s, and uses PCIe Gen 5 with 16 lanes versus Gen 3 with 16 lanes. These specifications suggest the Intel chip could win in multi-threaded workloads if benchmarks existed, but the data does not confirm that.

The Verdict

Based strictly on recorded data, the AMD Ryzen 5 PRO 5655G is the only processor with verified performance results. Its 80th percentile ranking and average score of 28032 show it performs in the upper range of all CPUs in the database, matching the performance of several Intel and AMD rivals within 0.3%. The Intel Core 7 251E, with no benchmark scores, cannot be compared on measured performance. Its specifications indicate a different design: more cores, a higher boost clock, and newer memory and PCIe standards. For users who require verified performance data, the AMD part is the only choice. For users who prioritize core count, memory flexibility, and PCIe generation, the Intel part offers those features on paper, but the database provides no evidence of how those translate into actual workload performance.

The production status of both parts is Active, and both use a 65 W TDP. The AMD processor uses AMD Socket AM4, while the Intel part uses Intel Socket 1700, so they are not platform-compatible. The AMD part has a release date in May 2024, while the Intel part was released in January 2025. The Intel chip has a launch MSRP of $384, but that is the only pricing information in the database, and it should not be used for value analysis.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, and the Intel Core 7 251E has zero benchmark scores. Therefore, a direct comparison of measured performance is impossible. The only data available is the AMD Ryzen 5 PRO 5655G's own benchmark results and its percentile position. The AMD chip's Cinebench R23 multi-core score of 17249 and single-core score of 2435 show a strong balance between single-threaded and multi-threaded capability. Its Passmark results include a multithread score of 19129, a single-thread score of 3241, and an integer math score of 67561. The floating point math score is 38649, and the extended instructions score is 17944.

The Intel Core 7 251E has no such data. Its architecture uses a different core layout, with 24 cores and 32 threads, which is 4 times the core count and 2.67 times the thread count of the AMD part. The base clock of 2.10 GHz is lower than the AMD's 3.90 GHz, but the boost clock of 5.60 GHz is 1.20 GHz higher. The L3 cache of 36 MB is 20 MB larger than the AMD's 16 MB. The Intel part also has a larger die size of 257 mm² compared to 180 mm², and it uses a 10 nm process versus the AMD's 7 nm process. These differences suggest the Intel part might excel in heavily parallel workloads, but the database does not confirm this.

The AMD's nearest rivals show its performance tier. The Intel Core i9-12900H, a high-end mobile processor, scores within 0.1% of the AMD part. The Intel Core i5-14500T, a low-power desktop chip, also scores within 0.1%. This indicates the Ryzen 5 PRO 5655G delivers performance comparable to both mobile and desktop Intel parts across their respective segments, despite having only 6 cores and 12 threads.

Architecture Differences

The AMD Ryzen 5 PRO 5655G uses the Zen 3 architecture, specifically the Cezanne codename, built on a 7 nm process by TSMC. It contains 10,700 million transistors on a 180 mm² die. The cache hierarchy is 64 KB of L1 per core, 512 KB of L2 per core, and a 16 MB L3 cache. The integrated graphics are Radeon Vega 7, and the processor supports ECC memory. It uses PCIe Gen 3 with 16 lanes, and its socket is AMD Socket AM4.

The Intel Core 7 251E uses the Bartlett Lake codename, built on a 10 nm process by Intel, with a die size of 257 mm². The cache is 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The integrated graphics are UHD Graphics 770, and it also supports ECC memory. It uses PCIe Gen 5 with 16 lanes, and its socket is Intel Socket 1700. The Intel part has no recorded transistor count, and its architecture field is null, meaning the database does not specify a named microarchitecture beyond the codename.

The core count difference is substantial: 6 cores and 12 threads for AMD versus 24 cores and 32 threads for Intel. This likely indicates different core types, but the database does not list performance or efficiency core counts. The AMD part's higher base clock of 3.90 GHz versus 2.10 GHz suggests higher per-core frequency at the base level, while the Intel part's 5.60 GHz boost clock suggests a higher maximum single-core frequency. The process node difference, 7 nm TSMC versus 10 nm Intel, affects transistor density and power characteristics, but the TDP is identical at 65 W for both.

The memory controller support differs: the AMD part is limited to DDR4, while the Intel part supports both DDR4 and DDR5. This gives the Intel chip access to higher memory bandwidth, 89.6 GB/s versus 51.2 GB/s, which could benefit memory-intensive workloads. The PCIe generation difference, Gen 3 versus Gen 5, affects available bandwidth for GPUs and storage devices, with Gen 5 offering significantly higher throughput per lane.
