Architecture Differences

The AMD Ryzen 9 9950X uses the Zen 5 architecture, codenamed Granite Ridge, and belongs to the 9000 series. It is built on a 4nm process at TSMC. The Intel Core 7 251TE uses the Bartlett Lake codename and is built on a 10nm process at Intel. The transistor counts differ substantially: AMD lists 16,630 million transistors across a die size of 2x 70.6 mm², while Intel does not provide a transistor count but lists a die size of 215 mm².

Cache configurations differ. The AMD processor has 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel processor also has 80 KB of L1 per core but a larger 1.25 MB of L2 per core and a smaller 36 MB of shared L3 cache. Memory support also differs: AMD supports DDR5 only, while Intel supports both DDR4 and DDR5. Both use dual-channel memory buses with identical memory bandwidth of 89.6 GB/s.

PCIe connectivity is another distinction. The AMD Ryzen 9 9950X offers Gen 5 with 24 lanes (CPU only), while the Intel Core 7 251TE offers Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well: AMD uses Radeon Graphics, while Intel uses UHD Graphics 770. Both processors support ECC memory. The AMD part has an unlocked multiplier, while the Intel part is locked.

Specification Differences

The core and thread counts differ despite both processors supporting 32 threads. The AMD Ryzen 9 9950X has 16 cores and 32 threads, while the Intel Core 7 251TE has 24 cores and 32 threads. Base clocks are significantly different: AMD runs at 4.30 GHz, while Intel runs at 1.40 GHz. Boost clocks are closer, with AMD at 5.70 GHz and Intel at 5.40 GHz. Thermal design power is a major distinction: AMD is rated at 170W, while Intel is rated at 45W.

The sockets differ: AMD uses Socket AM5, while Intel uses Socket 1700. The release dates also differ, with AMD launched on 2024-08-14 and Intel on 2025-01-12. The launch MSRP for the AMD part is $649, while the Intel part lists at $384. The Intel processor supports both DDR4 and DDR5 memory, whereas the AMD processor supports DDR5 only. Both support ECC memory. The AMD processor has a part number of 100-000001277, while the Intel part number is SRQAXQ5ZG. The AMD processor belongs to the 9000 series and is market-segmented as Desktop; the Intel unit is also Desktop.

The Verdict

The recorded data presents a clear picture: the AMD Ryzen 9 9950X is the stronger processor for the vast majority of workloads. Its 13 wins out of 15 head-to-head tests, combined with an average benchmark score of 74,640 versus 41,650 for Intel, establishes it as the higher-performing part overall. The AMD processor also holds a higher percentile ranking among all CPUs at 94, compared to 88 for Intel.

The Intel Core 7 251TE does have a distinct advantage in Cinebench R23 single-core, where it leads by 38.9%. That result suggests the Intel architecture can deliver strong single-threaded rendering performance, but it does not translate into broader single-thread dominance, as AMD wins PassMark single-thread by 32.8%. The Intel part also has a much lower TDP at 45W versus 170W, which indicates a different power profile, but the benchmark data does not show this resulting in competitive multi-threaded scores.

For users prioritizing multi-core throughput, data compression, encryption, or math-heavy tasks, the Ryzen 9 9950X is the clear choice. For those focused on Cinebench single-core rendering, the Intel Core 7 251TE offers the better score, but this is a narrow niche given the overall benchmark results.

Where Each One Wins

The AMD Ryzen 9 9950X wins in every multi-threaded and most single-threaded benchmarks. It dominates Cinebench R15 and R23 multi-core, PassMark multi-thread, integer math, floating-point math, data compression, data encryption, extended instructions, find prime numbers, random string sorting, and physics simulations. It also wins PassMark single-thread tests. This makes it the preferred option for compute-heavy tasks such as content rendering, data processing, scientific simulations, and encryption workloads.

The Intel Core 7 251TE wins in Cinebench R15 single-core by a slim 5% margin and in Cinebench R23 single-core by a substantial 38.9%. These wins point to a specific strength in single-threaded Cinebench rendering tasks. The Intel part also offers a lower TDP and support for both DDR4 and DDR5 memory, which may be relevant for certain system configurations, but the benchmark data does not show these features translating into broader performance wins.
