AMD Ryzen 9 9950X vs Intel Core i9-14901E Comparison

Head-to-Head Benchmarks

The benchmark data shows a decisive overall victory for the AMD Ryzen 9 9950X, which wins 13 of the 15 recorded head-to-head comparisons. The Intel Core i9-14901E takes only two wins, both in single-core Cinebench tests. The scale of AMD’s advantage is substantial, particularly in multi-threaded workloads where the core count difference is most impactful.

The largest margin recorded is in PassMark extended instructions, where the 9950X scores 71,564 versus 17,249 for the Intel chip, a 314.9% advantage. This indicates a massive gap in workloads that leverage modern SIMD and cryptographic instruction sets. Data compression shows a similar story: the AMD processor scores 896,544 against 288,777, a 210.5% lead. These are the kinds of tasks where the combination of more cores and newer architecture pays off dramatically.

In the broader multi-threaded picture, Cinebench R23 multicore has the 9950X at 40,924 while the i9-14901E manages 25,753, a 58.9% difference. The older Cinebench R15 multicore test shows an even larger relative gap at 144.1%, with scores of 6,335 versus 2,595. PassMark multithread confirms the trend at 66,030 versus 30,298, a 117.9% lead. Floating-point math is another strong point for AMD at 159,063 versus 81,089, a 96.2% margin. Integer math sits at 242,097 versus 112,736, a 114.7% advantage. Data encryption shows 44,366 versus 18,571, a 138.9% gap. Random string sorting rounds out the major wins at 94,368 versus 39,138, a 141.1% lead.

Even in tests that are typically less parallel, the 9950X holds an edge. PassMark single-thread shows 4,737 versus 4,354, an 8.8% win for AMD. Prime number finding, which often favors raw single-thread speed, goes to AMD at 345 versus 189, an 82.5% margin. Physics simulation records 3,279 versus 3,041, a modest 7.8% advantage.

The Intel processor’s two wins come exclusively in Cinebench single-core tests. In R15 single-core, Intel posts 366 against AMD’s 344, a 6% margin. In R23 single-core, the gap widens to 39.4% with Intel at 3,635 and AMD at 2,202. These results are notable because they run counter to the PassMark single-thread result, but Cinebench’s specific rendering workload clearly favors the Intel architecture’s peak frequency and IPC characteristics in that benchmark.

The average benchmark score across all recorded tests reinforces the split: the 9950X sits at 74,640, while the i9-14901E trails at 37,911. The AMD part occupies the 94th percentile among all CPUs, while Intel sits at the 86th percentile. The nearest rivals for the 9950X include the AMD Ryzen 7 PRO 9745 (0.2% slower on average), the AMD Ryzen AI 9 HX PRO 475 (0.2% faster), the AMD EPYC 4545P (1% faster), and the Intel Core Ultra 9 285 (1.1% faster). The Intel i9-14901E’s nearest rivals are the AMD Ryzen AI 9 HX 370 (0% delta), the AMD Ryzen 7 9700X (0.1% faster), the Intel Core 5 211E (0.2% slower), and the AMD Ryzen AI Embedded P132 (0.3% slower).

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 9 9950X is built on the Zen 5 architecture, codenamed Granite Ridge, and belongs to the Ryzen 9 generation. It uses a 4 nm process node manufactured by TSMC. The Intel Core i9-14901E is based on Raptor Lake, specifically the Raptor Lake-R codename, and represents the Core 14th Gen family. Intel fabricates this chip on a 10 nm process at its own foundries.

The most obvious architectural divergence is core count. AMD provides 16 cores and 32 threads, while Intel provides 8 cores and 16 threads. This doubling of resources explains much of the multi-threaded performance gap seen in the benchmarks. The AMD chip also has a higher thermal design power at 170 watts versus Intel’s 65 watts, indicating a much more aggressive power envelope.

Cache hierarchies differ markedly. Both processors share an identical L1 cache of 80 KB per core. However, the L2 cache splits: AMD uses 1 MB per core, while Intel uses 2 MB per core. The L3 cache favors AMD at 64 MB, versus Intel’s 36 MB shared pool. The transistor count is only listed for AMD at 16,630 million, with Intel’s figure not recorded. Die size shows AMD using a dual-die design at 2x 70.6 mm², while Intel uses a monolithic 257 mm² die.

Memory support is another differentiator. AMD supports DDR5 exclusively with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. Intel supports both DDR4 and DDR5 memory, also on a dual-channel bus, though its memory bandwidth is not recorded in the database. Both platforms support ECC memory.

PCI Express connectivity differs in lane count. AMD provides Gen 5 with 24 CPU-only lanes, while Intel provides Gen 5 with 16 CPU-only lanes. Integrated graphics solutions also diverge: AMD includes Radeon Graphics, while Intel includes UHD Graphics 770.

The AMD processor has an unlocked multiplier, enabling overclocking, while Intel’s multiplier is locked. The AMD part also carries a launch MSRP of $649, while Intel’s launch MSRP is not recorded. Release dates place the AMD chip at August 14, 2024, and the Intel chip earlier on June 30, 2024.

The Verdict

The data supports a clear split in use cases. The AMD Ryzen 9 9950X is the choice for any workload that scales with core count and thread count. Its 16 cores and 32 threads deliver margins ranging from 7.8% in physics to 314.9% in extended instructions. The database shows the 9950X at the 94th percentile among all CPUs, with an average benchmark score of 74,640. For rendering, data compression, encryption, and heavy math workloads, the AMD part is categorically faster.

The Intel Core i9-14901E offers a different profile. Its 8 cores and 16 threads are sufficient for lighter multi-threaded tasks, and its single-core Cinebench results are superior. The 39.4% win in Cinebench R23 single-core is the largest single advantage recorded for either processor. The Intel chip also operates at a 65 watt TDP, which is 105 watts lower than AMD’s 170 watt rating. This suggests a lower-power option for systems where thermal and power constraints matter more than peak throughput.

The average benchmark score difference of 36,729 points (74,640 vs 37,911) is substantial. The Intel part sits at the 86th percentile, 8 percentile points behind AMD. Its nearest rivals include the AMD Ryzen 7 9700X and the AMD Ryzen AI 9 HX 370, while AMD’s nearest rivals are higher-end parts like the Intel Core Ultra 9 285 and AMD EPYC 4545P.

For users who prioritize raw multi-threaded throughput, the recorded data points decisively to the AMD Ryzen 9 9950X. For users who need the best Cinebench single-core scores and a lower power draw, the Intel Core i9-14901E holds specific advantages. The locked multiplier on Intel and the unlocked multiplier on AMD also factor into flexibility, with AMD offering overclocking headroom that Intel does not.
