AMD Ryzen 9 9950X3D vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The recorded data presents a direct comparison challenge: the AMD Ryzen 9 9950X3D has a full suite of 23 benchmark scores, while the Intel Core 7 251E has no recorded benchmark entries in the database. This means there are zero head-to-head benchmark results to compare directly, and neither processor registers a win in the head-to-head category. The analysis must therefore rely on the available metrics for the AMD part and the specification-level differences between the two.

For the AMD Ryzen 9 9950X3D, the benchmark data shows a processor that delivers strong multi-threaded performance. In Cinebench R23, the multi-core score is 42018, while the single-core score is 2259. This represents a multi-core to single-core ratio of roughly 18.6 to 1, indicating significant scaling across its 16 cores and 32 threads. The Geekbench results follow a similar pattern: a multi-core score of 26736 against a single-core score of 3064, a ratio of approximately 8.7 to 1.

The 3DMark tests provide a more granular view of thread scaling. The 2-thread score is 2549, the 4-thread score is 4963, the 8-thread score is 9259, and the 16-thread score is 16374. The max-thread score reaches 17184. The progression from 2 to 4 threads shows a 94.7% increase, from 4 to 8 threads a 86.6% increase, and from 8 to 16 threads a 76.9% increase. The relatively small gain from 16 threads (16374) to max threads (17184) is only 4.9%, which suggests that the additional threads beyond 16 provide diminishing returns in this particular workload, likely due to the test's scaling limits rather than a processor deficiency.

PassMark results further characterize the AMD part's capabilities. The multi-thread score is 70255, while the single-thread score is 4737. The integer math score is 243209, and the floating point math score is 159724. The extended instructions score is 73011, which indicates strong SIMD and vector processing performance. Data encryption scores 44536, while data compression scores 908421. The random string sorting test shows 95423, and the find prime numbers test shows 613. The physics score is 5670.

The AMD Ryzen 9 9950X3D holds a 95th percentile ranking against all CPUs in the database. Its average benchmark score is 75779. Its nearest rivals, based on average score, are the AMD Ryzen 7 PRO 9755 at 75738 (0.1% behind), the AMD Ryzen 7 PRO 9755X3D at 75716 (0.1% behind), the AMD EPYC 8224P at 75582 (0.3% behind), and the Intel Core Ultra 9 285 at 75488 (0.4% behind). These delta percentages are extremely tight, indicating that the 9950X3D sits at the top of a very closely clustered group of high-performance processors.

Where Each One Wins

Without any benchmark scores recorded for the Intel Core 7 251E, the wins analysis is one-sided. The AMD Ryzen 9 9950X3D has measurable wins in every benchmark category where data exists. These include single-threaded, multi-threaded, and specialized workloads such as data encryption, compression, floating point math, and integer math.

The Intel Core 7 251E, with an empty benchmark array, cannot be attributed any performance wins based on the recorded data. Its percentile ranking is 50th across all CPUs, but this figure is not backed by any specific test scores. The average benchmark score is listed as 0, which aligns with the absence of recorded test results.

Given that the database contains no head-to-head results, the practical interpretation is that the AMD processor demonstrates measurable performance across all tested workloads, while the Intel processor's performance characteristics remain unquantified in the database. The AMD part's wins are therefore absolute within the available data, but this is a function of data completeness rather than a demonstrated superiority in every possible workload.

The AMD Ryzen 9 9950X3D's performance profile suggests it is well-suited for workloads that benefit from high thread counts, given its Cinebench R23 multi-core score of 42018 and Geekbench multi-core score of 26736. Its single-thread performance, with a Cinebench R23 single-core score of 2259 and a Geekbench single-core score of 3064, also indicates strong per-core capability. The PassMark data compression score of 908421 is notably high, suggesting strong memory subsystem performance for compression workloads.

The Intel Core 7 251E, with 24 cores and 32 threads, has a higher core count than the AMD part, but the absence of benchmark data prevents any assessment of how those cores perform in practice. Its lower base clock of 2.10 GHz and boost clock of 5.60 GHz, compared to the AMD part's 4.30 GHz base and 5.70 GHz boost, provide a specification-level hint, but without test scores, no performance conclusion can be drawn.

Thermal design power is another major differentiator: the AMD part is rated at 170 watts, while the Intel part is rated at 65 watts.

The sockets are incompatible: the AMD part uses AMD Socket AM5, while the Intel part uses Intel Socket 1700. The memory support differs as well: the AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. Both use a dual-channel memory bus with identical memory bandwidth of 89.6 GB/s. Both support ECC memory.

PCIe lane counts differ: the AMD part provides Gen 5 with 24 lanes (CPU only), while the Intel part provides Gen 5 with 16 lanes (CPU only). The integrated graphics differ: the AMD part uses Radeon Graphics, while the Intel part uses UHD Graphics 770.

The multiplier is unlocked on the AMD part, but locked on the Intel part. The launch MSRP differs: the AMD part launched at $699, while the Intel part launched at $384. The release dates are close, with the AMD part released on January 5, 2025, and the Intel part released on January 12, 2025.

Architecture Differences

The AMD Ryzen 9 9950X3D is built on the Zen 5 architecture with the codename Granite Ridge, part of the 9000 series. It uses a 4 nm process node manufactured by TSMC. The processor contains 16,630 million transistors across a die size of 2x 70.6 mm². Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 128 MB of L3 cache.

The Intel Core 7 251E uses the Bartlett Lake codename, part of the Core 7 generation. It is built on a 10 nm process node manufactured by Intel, with a die size of 257 mm². The transistor count is not recorded in the database. Its cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache.

The process node difference is substantial: 4 nm versus 10 nm, which typically indicates a significant difference in transistor density and power efficiency. The AMD part's dual-die design with 2x 70.6 mm² dies contrasts with the Intel part's single 257 mm² die. The L3 cache difference is notable: the AMD part has 128 MB, while the Intel part has 36 MB, a difference of 92 MB. The L2 cache per core is larger on the Intel part at 2 MB versus 1 MB on the AMD part.

The architecture field for the Intel part is listed as null in the database, meaning no specific architecture name is recorded, only the codename Bartlett Lake. The AMD part explicitly states Zen 5. The generation field shows "Ryzen 9 (Zen 5 (Granite Ridge))" for the AMD part and "Core 7 (Bartlett Lake)" for the Intel part.

Both processors use dual-channel memory and support ECC. The AMD part's memory bandwidth is 89.6 GB/s, and the Intel part matches this exactly at 89.6 GB/s. The PCIe implementation differs in lane count, with the AMD part offering 24 lanes versus 16 lanes on the Intel part, both at Gen 5 speed.
