AMD Ryzen 7 7700X3D vs Intel Core 7 251TE Comparison

AMD Ryzen 7 7700X3D and Intel Core 7 251TE represent two very different approaches to desktop processing. The AMD part is a high-frequency 8-core chip built on a 5 nm process with a massive 96 MB shared L3 cache, while Intel counters with a 24-core, 32-thread design on a 10 nm node that runs at a much lower base clock but boosts higher. The recorded data shows a clear split: Intel dominates multi-threaded workloads with its larger core count, while the AMD chip’s architecture targets different strengths. The database contains benchmark results for the Intel chip, while the AMD chip has no recorded benchmark scores, so the analysis relies on architectural and specification differences alongside the Intel data for context.

Architecture Differences

The two processors come from different manufacturing and design philosophies. AMD uses a 5 nm process node built by TSMC, while Intel uses a 10 nm process from its own foundry. The AMD chip has a die size of 71 mm² and contains 11,270 million transistors. Intel’s die size is 215 mm², and the database does not list a transistor count for it. This means the AMD chip packs roughly three times the transistor density per square millimeter, though the Intel chip has a physically larger die.

Cache hierarchy differs substantially. The AMD Ryzen 7 7700X3D uses 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a shared 96 MB L3 cache. The Intel Core 7 251TE uses 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 36 MB L3 cache. The AMD chip’s L3 cache is 60 MB larger, which typically helps with repeated data access in certain workloads. Intel’s per-core L1 and L2 caches are larger, at 16 KB and 0.25 MB more per core respectively.

The memory controllers also differ. AMD supports DDR5 only with dual-channel access, while Intel supports both DDR4 and DDR5 with dual-channel access. Intel’s memory bandwidth rating of 89.6 GB/s is higher than AMD’s 83.2 GB/s. Both processors support ECC memory.

PCIe lane counts differ. AMD provides Gen 5 with 24 lanes from the CPU, while Intel provides Gen 5 with 16 lanes from the CPU. The AMD chip also includes integrated Radeon Graphics, whereas Intel includes UHD Graphics 770.

The AMD part uses the AMD Socket AM5, while Intel uses Socket 1700. Both processors have locked multipliers, so neither supports manual overclocking. Intel’s codename is Bartlett Lake, and AMD’s is Raphael. AMD belongs to the 7000 series with a Zen 4 (Raphael) generation, while Intel is in the Core 7 (Bartlett Lake) generation.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between these two specific processors. However, benchmark data exists for the Intel Core 7 251TE, and its percentile ranking provides context. The Intel chip scores in the 88th percentile against all CPUs in the database, with an average benchmark score of 41,650.

Intel’s nearest rivals in the database include the Intel Core Ultra 7 265H with an average score of 41,621 and a delta of 0.1 percent, meaning the 251TE is effectively tied with it. The Intel Core i7-14650HX scores 41,576, which is 0.2 percent lower. The Intel Core i7-12850HX scores 41,779, which is 0.3 percent higher. The Intel Core i7-14700T scores 41,914, which is 0.6 percent higher.

Looking at Intel’s benchmark results, the multi-threaded scores are strong. In Cinebench R23 multi-core, the Intel chip scores 25,518. In Cinebench R20 multi-core, it scores 10,717, and in Cinebench R15 multi-core, it scores 2,572. Single-core results show 3,602 in Cinebench R23, 1,512 in Cinebench R20, and 362 in Cinebench R15.

PassMark results for Intel show strong integer math performance at 125,739, floating point math at 85,607, and multithread at 30,022. Data compression scores 334,399, and data encryption scores 22,176. Extended instructions score 16,974, and random string sorting scores 39,643. Physics scores 1,938, and find prime numbers scores 140. Single-thread performance in PassMark is 3,568.

The AMD processor has no recorded benchmark scores in the database, so direct numerical comparisons cannot be made. The data shows that Intel’s core count advantage of 24 cores versus 8 cores likely drives its multi-threaded scores, but the absence of AMD benchmark data means the exact deltas remain unrecorded.

The Verdict

The data points to a clear division of roles. The Intel Core 7 251TE is the multi-threaded workhorse, with 24 cores, 32 threads, and an 88th percentile ranking against all CPUs. Its Cinebench R23 multi-core score of 25,518 and PassMark multithread score of 30,022 confirm strong parallel throughput. The AMD Ryzen 7 7700X3D, with only 8 cores and 16 threads, cannot match that core count, and the database shows no benchmark scores for it to argue otherwise.

For single-thread performance, Intel’s boost clock of 5.40 GHz is higher than AMD’s 4.50 GHz, and Intel’s PassMark single-thread score of 3,568 reflects that. The AMD chip has a much higher base clock at 4.00 GHz versus 1.40 GHz, but the boost clock matters more for bursty single-thread tasks.

The AMD processor’s 96 MB L3 cache is its standout feature, but without benchmark data, its practical impact cannot be quantified. The Intel chip has a lower TDP at 45 watts versus 120 watts, which indicates lower power draw under sustained loads, though the database does not list actual power consumption figures.

Users who need maximum multi-threaded throughput for rendering, compilation, or data processing should look at the Intel part based on its recorded scores. Users who prioritize the large L3 cache and higher base clock of the AMD chip have no benchmark evidence in the database to confirm those advantages translate into wins.

Where Each One Wins

Multi-threaded compute: The Intel Core 7 251TE wins decisively on paper. Its 24 cores and 32 threads versus AMD’s 8 cores and 16 threads give it a 16-core and 16-thread advantage. The recorded Cinebench R23 multi-core score of 25,518 and PassMark multithread score of 30,022 show strong parallel scaling. This chip is suited for video rendering, 3D simulation, and batch data processing where core count drives throughput.

Single-thread burst performance: Intel also holds the advantage here based on its boost clock of 5.40 GHz, which is 0.90 GHz higher than AMD’s 4.50 GHz. The PassMark single-thread score of 3,568 reflects that capability. For lightly threaded tasks like web browsing, office work, or older games that rely on one or two cores, Intel’s higher boost clock should deliver faster response times.

Cache-sensitive workloads: The AMD Ryzen 7 7700X3D has a 96 MB shared L3 cache, which is 60 MB larger than Intel’s 36 MB. This large cache can reduce memory latency for data that fits within it, which historically helps in certain simulation and gaming scenarios. However, the database contains no benchmark scores for the AMD chip, so the actual performance benefit is not recorded.

Power efficiency: Intel’s TDP of 45 watts is significantly lower than AMD’s 120 watts. For compact builds, small form factor systems, or environments where heat output matters, the Intel chip has a clear specification advantage. The lower TDP also suggests lower sustained power draw, though exact wattage figures are not in the database.

Platform flexibility: Intel supports both DDR4 and DDR5 memory, while AMD supports only DDR5. This gives builders using the Intel Socket 1700 platform the option to reuse existing DDR4 memory, potentially lowering system cost, though the database does not list pricing for memory.

PCIe expansion: AMD provides 24 PCIe Gen 5 lanes from the CPU, compared to Intel’s 16 lanes. This gives AMD an 8-lane advantage for high-speed storage or multiple expansion cards, which is a meaningful difference for workstation builds that need more direct CPU-attached devices.

Integrated graphics: Both chips include integrated graphics, with AMD using Radeon Graphics and Intel using UHD Graphics 770. Neither is a dedicated GPU, but both can drive displays without a discrete card. The database does not list performance metrics for either iGPU.
