AMD Ryzen 7 5700X3D vs Intel Core 7 251TE Comparison

AMD Ryzen 7 5700X3D and Intel Core 7 251TE represent two distinct approaches to desktop processing, one built around a mature socket and large cache, the other around a high core count and modern platform features. The benchmark data shows a clear split in workload suitability, with the Intel part dominating most multi-threaded and single-threaded tests, while the AMD part wins specific math and physics workloads.

Head-to-Head Benchmarks

The Intel Core 7 251TE wins 14 of the 17 recorded head-to-head comparisons, establishing a wide lead in most everyday and productivity metrics. In Cinebench tests, the Intel processor is consistently ahead by 12.4 percent across R15, R20, and R23 multi-core and single-core runs. For example, Cinebench R23 multi-core shows the Intel part scoring 25518 against the AMD Ryzen 7 5700X3D's 22366, and single-core R23 shows 3602 versus 3157. This uniformity suggests a fundamental clock and architecture advantage rather than a workload-specific quirk.

The Intel part also wins PassMark integer math with a score of 125739 against 81257, a 35.4 percent margin, and floating-point math with 85607 versus 46492, a 45.7 percent margin. Data compression favors Intel at 334399 versus 307237, an 8.1 percent gap, while data encryption shows Intel ahead by 15.3 percent (22176 versus 18788). Random string sorting, a memory-latency-sensitive test, goes to Intel by 20.6 percent (39643 versus 31492). PassMark multi-thread scores show Intel at 30022 versus 26318, a 12.3 percent lead, and single-thread scores show Intel at 3568 versus 2970, a 16.8 percent margin.

The AMD Ryzen 7 5700X3D wins the remaining three tests, and these wins are notable for their magnitude. PassMark extended instructions show AMD at 21202 versus Intel's 16974, a 24.9 percent advantage. PassMark find prime numbers shows AMD at 224 versus 140, a massive 60 percent lead. PassMark physics shows AMD at 2686 versus 1938, a 38.6 percent margin. These three wins indicate the AMD part has a specific strength in instruction-level parallelism and integer-heavy calculation loops, likely tied to its large cache and Zen 3 core design.

The aggregate data reinforces this split. The AMD part's average benchmark score is 24709, placing it in the 77th percentile of all CPUs, while the Intel part's average score is 41650, placing it in the 88th percentile. The Intel part's nearest rivals are the Intel Core Ultra 7 265H (0.1 percent ahead) and Intel Core i7-14650HX (0.2 percent ahead), while the AMD part sits within 0.6 percent of the Intel Core i5-11600 and 0.5 percent behind the Intel Core i5-12450HX.

Architecture Differences

The two processors come from different manufacturing and design generations. The AMD Ryzen 7 5700X3D uses the Zen 3 architecture on the Vermeer codename, built on a 7 nm process at TSMC. It has a die size of 74 mm² with 8,850 million transistors. The Intel Core 7 251TE uses the Bartlett Lake codename, built on a 10 nm process at Intel foundries, with a die size of 215 mm². The process node difference is reflected in the transistor density, though the Intel part trades that for a substantially larger physical die.

Core counts differ dramatically. The AMD part has 8 cores and 16 threads, while the Intel part has 24 cores and 32 threads. This core count disparity explains the Intel part's lead in multi-threaded benchmarks, but the AMD part compensates with a much larger L3 cache. The AMD Ryzen 7 5700X3D has 96 MB of shared L3 cache, while the Intel part has 36 MB of shared L3. Per-core cache sizes also differ: AMD provides 64 KB of L1 and 512 KB of L2 per core, while Intel provides 80 KB of L1 and 1.25 MB of L2 per core.

Clock speeds favor Intel significantly. The AMD part has a base clock of 3.00 GHz and a boost clock of 4.10 GHz, while the Intel part has a base clock of 1.40 GHz and a boost clock of 5.40 GHz. The Intel part's low base clock with high boost clock suggests a power-managed design, consistent with its 45 W TDP versus the AMD part's 105 W TDP. Memory support also differs: AMD uses DDR4 with dual-channel and 51.2 GB/s bandwidth, while Intel supports both DDR4 and DDR5 with dual-channel and 89.6 GB/s bandwidth. Both support ECC memory.

The Intel part includes integrated graphics (UHD Graphics 770), while the AMD part has no integrated graphics. PCIe support differs as well: AMD provides Gen 4 with 20 lanes, while Intel provides Gen 5 with 16 lanes. The AMD part uses the AMD Socket AM4, while the Intel part uses Intel Socket 1700. The AMD part's release date is January 7, 2024, while the Intel part's release date is January 12, 2025.

The Verdict

The data points to a clear division of roles. The Intel Core 7 251TE is the stronger processor for multi-threaded productivity, rendering, and general computation. Its 24 cores and 32 threads, combined with a 5.40 GHz boost clock, deliver consistent 12.4 percent wins across all Cinebench versions and a 35.4 percent lead in integer math. It also holds a 45.7 percent lead in floating-point math, making it the choice for workloads that scale across cores and benefit from high peak clocks.

The AMD Ryzen 7 5700X3D is the better option for specific calculation-heavy tasks. Its wins in PassMark extended instructions (24.9 percent), find prime numbers (60 percent), and physics (38.6 percent) indicate a strength in tightly-looping integer workloads, likely enhanced by the 96 MB L3 cache. The AMD part also carries a lower launch MSRP of $249 versus Intel's $384, though the performance data shows the Intel part in a higher percentile overall (88th versus 77th).

For users on an existing AM4 platform, the AMD part offers a drop-in upgrade path with ECC support and a 105 W TDP. For those building new on Intel Socket 1700, the Intel part provides integrated graphics, DDR5 support, and a 45 W TDP with a 5.40 GHz boost clock. The benchmark results show the Intel part winning 14 of 17 head-to-head tests, but the three AMD wins are substantial in their respective domains. The choice depends on whether the workload favors raw multi-thread throughput or specific instruction-heavy loops where the AMD part's cache and core design excel.
