# The Verdict

The data clearly indicates that the AMD Ryzen Threadripper PRO 9955WX is the dominant processor in this comparison. In every head-to-head benchmark recorded, the AMD chip won, with a 6-0 win record. The Intel Core i5-14401E did not register a single victory in any of the six tests.

For workloads that demand massive multi-threaded performance, the AMD Ryzen Threadripper PRO 9955WX is the only sensible choice. Its 16 cores and 32 threads, combined with a 4.50 GHz base and 5.40 GHz boost, deliver scores that are more than triple those of the Intel part in multi-core tests. The AMD chip also leads in single-core performance by a similar margin, meaning it is faster not only in parallel workloads but also in tasks that rely on a single thread.

The Intel Core i5-14401E, with its 6 cores and 12 threads, is a lower-end desktop chip. It has a lower average benchmark score and a lower percentile ranking. The data does not support any scenario where the Intel processor would outrun the AMD processor in the tested benchmarks. The Intel part may be suitable for basic desktop tasks, but the recorded scores show it is far behind in every measurable category.

The AMD Ryzen Threadripper PRO 9955WX is the clear pick for anyone needing maximum compute power. The Intel Core i5-14401E is a more modest processor that cannot compete with the AMD chip on any benchmark in the database.

# Head-to-Head Benchmarks

The head-to-head results are one-sided. In Cinebench R15 multi-core, the AMD Ryzen Threadripper PRO 9955WX scored 5996 against the Intel Core i5-14401E's 1830, a delta of 227.7%. In Cinebench R15 single-core, the AMD chip scored 846 versus 258, a delta of 227.9%.

Cinebench R20 multi-core shows the AMD part at 24987 and the Intel part at 7627, a delta of 227.6%. In Cinebench R20 single-core, the AMD chip scored 3527 against 1076, a delta of 227.8%.

Cinebench R23 multi-core results are 59494 for the AMD chip and 18161 for the Intel chip, a delta of 227.6%. In Cinebench R23 single-core, the AMD chip scored 8399 versus 2564, a delta of 227.6%.

Every delta is approximately 227.6% or 227.7%, meaning the AMD processor consistently delivers roughly 3.3 times the performance of the Intel processor across all six tests. The margin is uniform, indicating that the performance gap is consistent regardless of the specific workload within the Cinebench suite.

The AMD chip also holds a higher average benchmark score. The AMD Ryzen Threadripper PRO 9955WX has an average benchmark score of 101041, while the Intel Core i5-14401E has an average of 5253. The AMD chip's percentile rank is 97, while the Intel chip's rank is 60.

# Where Each One Wins

The AMD Ryzen Threadripper PRO 9955WX wins in all six recorded head-to-head benchmarks. This includes both multi-core and single-core tests across Cinebench R15, R20, and R23. The AMD chip's wins are not marginal; they are substantial, with deltas exceeding 227% in every case.

The Intel Core i5-14401E has zero wins in the head-to-head benchmarks. The database records no test where the Intel processor outperforms the AMD processor.

From the broader benchmark data, the AMD chip shows strong results in additional areas. In PassMark tests, the AMD chip scored 920954 in data compression, 44389 in data encryption, 76363 in extended instructions, 337 in find prime numbers, 156215 in floating point math, 236120 in integer math, 67035 in multithread, 4156 in physics, 99813 in random string sorting, and 4530 in single-thread. These scores are not directly compared to the Intel chip in the head-to-head table, but they contribute to the AMD chip's higher average benchmark score.

The Intel Core i5-14401E, with only Cinebench scores recorded, shows a much lower performance envelope. Its highest recorded score is 18161 in Cinebench R23 multi-core, which is less than one-third of the AMD chip's score in the same test.

The use-case split is therefore clear. The AMD Ryzen Threadripper PRO 9955WX is the processor for heavy compute workloads, content creation, rendering, and any task that benefits from high core counts and high clock speeds. The Intel Core i5-14401E is a much less capable part, with no recorded advantage in any benchmark. For a builder choosing between these two, the data points exclusively to the AMD processor.
