AMD Ryzen 5 5500X3D vs Intel Core 7 251TE Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the Intel Core 7 251TE, which wins 9 of the 11 recorded comparisons. The AMD Ryzen 5 5500X3D manages only 2 wins, but those wins are concentrated in workloads that favor its unique architecture. The Intel part takes a commanding lead in raw throughput, while the AMD chip claims specialized wins in prime number calculation and physics simulation.

The largest single delta appears in floating point math, where the Intel Core 7 251TE scores 85,607 against the AMD Ryzen 5 5500X3D's 34,511. That is a 59.7% advantage for Intel. The gap is nearly as large in integer math: Intel scores 125,739 versus 60,033, a 52.3% lead. These two results indicate that the Intel processor's core configuration is far more effective at sustained arithmetic workloads. The data suggests the Intel part delivers more than double the throughput in these areas.

In multithreaded performance, the Intel Core 7 251TE posts a score of 30,022, which is 32.2% higher than the Ryzen's 20,363. This aligns with the core count difference, as the Intel part features 24 cores and 32 threads against the AMD's 6 cores and 12 threads. The multithread result is a strong indicator of the Intel processor's advantage in heavily parallel tasks.

Data compression shows a similar pattern. The Intel Core 7 251TE scores 334,399 versus 230,392, a 31.1% lead. Encryption workloads are even more lopsided: Intel scores 22,176 versus 13,967, a 37% advantage. Random string sorting, another memory-heavy workload, shows Intel ahead with 39,643 against 23,675, a 40.3% margin. The Intel core's higher memory bandwidth of 89.6 GB/s, compared to the AMD's 51.2 GB/s, likely explains part of this gap.

Single-thread performance also favors Intel. The Core 7 251TE scores 3,568 in the PassMark single-thread test, which is 17.6% higher than the Ryzen 5 5500X3D's 2,941. The Intel part's 5.40 GHz boost clock far exceeds the AMD's 4.00 GHz, and the data reflects that difference. Extended instructions show a smaller margin: Intel leads 16,974 to 15,925, a 6.2% edge.

The AMD Ryzen 5 5500X3D's two wins are worth examining closely. In prime number calculation, the AMD part scores 170 against Intel's 140, a 21.4% advantage. This workload often benefits from cache size, and the AMD chip's 96 MB of shared L3 cache is likely the deciding factor. In physics simulation, the AMD part scores 2,282 versus 1,938, a 17.8% lead. Physics workloads also typically respond well to large caches and lower-latency memory access patterns.

The average benchmark scores tell the same story. The Intel Core 7 251TE has an average score of 41,650, while the AMD Ryzen 5 5500X3D averages 37,018. The Intel part also ranks higher in the overall percentile, sitting at the 88th percentile of all CPUs compared to the AMD's 85th. The nearest rivals for each part confirm their positioning: the AMD chip trades blows with the AMD Ryzen 5 5600F, Intel Core Ultra 5 225, and Intel Core i9-12900T, all within 0.3% of its average score. The Intel chip competes with the Intel Core Ultra 7 265H, Intel Core i7-14650HX, and Intel Core i7-12850HX, also within a narrow band.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 5 5500X3D uses the Zen 3 architecture under the Vermeer codename, built on a 7 nm process at TSMC. The Intel Core 7 251TE uses the Bartlett Lake codename, built on a 10 nm process at Intel's own foundry. The AMD chip has a die size of 74 mm², while the Intel chip measures 215 mm². Both are active production parts.

Core counts differ dramatically. The AMD Ryzen 5 5500X3D has 6 cores and 12 threads. The Intel Core 7 251TE has 24 cores and 32 threads. The cache hierarchy is equally divergent. The AMD part offers 64 KB of L1 cache per core, 512 KB of L2 cache per core, and a massive 96 MB of shared L3 cache. The Intel part offers 80 KB of L1 per core, 1.25 MB of L2 per core, but only 36 MB of shared L3. The AMD's 96 MB L3 cache is the standout architectural feature, and it directly explains the AMD chip's wins in cache-sensitive workloads like prime number calculation and physics simulation.

Memory support also differs. The AMD Ryzen 5 5500X3D supports DDR4 memory in a dual-channel configuration with 51.2 GB/s of bandwidth. The Intel Core 7 251TE supports both DDR4 and DDR5 in dual-channel mode, with 89.6 GB/s of bandwidth. Both parts support ECC memory. PCIe connectivity splits along generational lines: the AMD chip provides PCIe Gen 4 with 20 CPU lanes, while the Intel chip provides PCIe Gen 5 with 16 CPU lanes.

Integrated graphics is another major differentiator. The AMD Ryzen 5 5500X3D has no integrated graphics. The Intel Core 7 251TE includes UHD Graphics 770. This matters for systems built without a discrete GPU, though the benchmark data does not include graphics tests. Both processors have locked multipliers, so neither supports overclocking via multiplier adjustment. The AMD part has a TDP of 105 watts, while the Intel part has a TDP of 45 watts, a significant power envelope difference.

The release dates are close. The AMD Ryzen 5 5500X3D launched on June 4, 2025. The Intel Core 7 251TE launched on January 12, 2025. The AMD part carries part number 100-000001504, and the Intel part carries part number SRQAXQ5ZG.

Specification Differences

The specifications that differ between the two processors are numerous. The AMD Ryzen 5 5500X3D has 6 cores and 12 threads, while the Intel Core 7 251TE has 24 cores and 32 threads. Base clocks differ substantially: the AMD part runs at 3.00 GHz, while the Intel part runs at 1.40 GHz. Boost clocks flip the comparison: the AMD part boosts to 4.00 GHz, while the Intel part boosts to 5.40 GHz.

TDP is a major point of separation. The AMD Ryzen 5 5500X3D has a TDP of 105 watts. The Intel Core 7 251TE has a TDP of 45 watts. Socket compatibility differs as well: the AMD chip uses AMD Socket AM4, and the Intel chip uses Intel Socket 1700.

Cache configurations are entirely different. The AMD part has 64 KB of L1 per core, 512 KB of L2 per core, and 96 MB of shared L3. The Intel part has 80 KB of L1 per core, 1.25 MB of L2 per core, and 36 MB of shared L3. Memory support shows the AMD part limited to DDR4, while the Intel part supports both DDR4 and DDR5. Memory bandwidth is 51.2 GB/s for AMD and 89.6 GB/s for Intel. PCIe generation and lane counts differ: Gen 4 with 20 lanes for AMD, Gen 5 with 16 lanes for Intel. The AMD part has no integrated graphics, while the Intel part includes UHD Graphics 770.

The process node and foundry also differ. AMD uses a 7 nm process at TSMC. Intel uses a 10 nm process at its own foundry. Die size is 74 mm² for AMD and 215 mm² for Intel. The Intel part has a launch MSRP of $384. The AMD part has no launch MSRP recorded in the database. Both parts are active production parts with locked multipliers.

The Verdict

The benchmark data supports a clear split decision based on workload. The Intel Core 7 251TE is the stronger processor for most tasks. Its 24 cores and 32 threads deliver a 32.2% lead in multithreaded performance, and its higher boost clock of 5.40 GHz contributes to a 17.6% single-thread advantage. The Intel part wins 9 of 11 head-to-head tests, including large margins in floating point math, integer math, data compression, encryption, and random string sorting. Its average benchmark score of 41,650 places it in the 88th percentile of all CPUs. The Intel part also offers integrated graphics, support for both DDR4 and DDR5, and a much lower TDP of 45 watts. The launch MSRP is $384.

The AMD Ryzen 5 5500X3D is the more specialized choice. Its 96 MB of shared L3 cache gives it a 21.4% win in prime number calculation and a 17.8% win in physics simulation. Those are the only two tests it wins, but they point to a consistent strength in cache-sensitive workloads. The AMD part sits in the 85th percentile with an average score of 37,018, and its nearest rivals include the AMD Ryzen 5 5600F and Intel Core Ultra 5 225, both within 0.2% of its average. The AMD chip uses the AM4 socket, supports only DDR4, has no integrated graphics, and carries a 105 watt TDP.

For users prioritizing maximum throughput across a broad range of workloads, the recorded data favors the Intel Core 7 251TE. For workloads that depend heavily on large cache capacity, such as prime number calculations and physics simulations, the AMD Ryzen 5 5500X3D shows a measurable advantage. The two processors target different priorities, and the benchmark results reflect those distinct design goals.
