Intel Core i9-14901KE vs Intel Core Ultra 5 235 Comparison

The Verdict

The Intel Core i9-14901KE and Intel Core Ultra 5 235 occupy completely different positions in the desktop processor landscape. The i9-14901KE is a high-core-count, high-clock part aimed at users who need maximum single-threaded responsiveness and traditional multithreaded throughput. The Core Ultra 5 235 is a more power-conscious, efficiency-focused design that still delivers strong all-around performance.

Benchmark data is only available for the Core Ultra 5 235, which sits at the 89th percentile of all CPUs in the database with an average benchmark score of 46062. Its nearest rivals include the AMD Ryzen AI 9 HX 375 (0.1% ahead), the Intel Core i9-13900HX (0.1% behind), and the AMD EPYC 4364P (0.2% ahead). This places the Core Ultra 5 235 in a competitive tier that trades blows with high-end laptop and workstation parts. The i9-14901KE has no recorded benchmark scores in the database and sits at the 50th percentile with an average score of zero, meaning its performance cannot be directly quantified here.

For buyers choosing between the two, the decision hinges on platform compatibility and workload type. The i9-14901KE uses the Intel Socket 1700 platform with DDR4 or DDR5 memory support and ECC memory capability, making it suitable for existing LGA1700 builds or memory-flexible workstations. The Core Ultra 5 235 uses the newer Intel Socket 1851, supports only DDR5, and has no ECC memory support, but it offers more PCIe Gen 5 lanes and a significantly more advanced process node. Users needing maximum clock speed and legacy memory options should pick the i9-14901KE; those wanting a modern, efficient platform with higher overall CPU percentile ranking should pick the Core Ultra 5 235.

Architecture Differences

The i9-14901KE is built on Raptor Lake architecture with the Raptor Lake-R codename, part of the Core 14th Gen series. It uses Intel's 10 nm process node and is manufactured by Intel itself. The die size measures 257 mm². This is a traditional monolithic design with 8 cores and 16 threads, reflecting a hybrid approach where each core handles two threads via Hyper-Threading. The processor has an unlocked multiplier, allowing overclocking.

The Core Ultra 5 235 uses Arrow Lake architecture with the Arrow Lake-S codename, part of the Core Ultra Series 2. It is built on TSMC's 3 nm process node, a substantial manufacturing advantage over the i9-14901KE. The die contains 17,800 million transistors across a 243 mm² area, making it denser despite the smaller physical size. This processor has 14 cores and 14 threads, meaning it relies on a mix of performance and efficiency cores without simultaneous multithreading. The multiplier is locked, preventing traditional overclocking.

Cache configurations differ significantly. The i9-14901KE has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Core Ultra 5 235 has 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. The Core Ultra 5 235 has more per-core cache capacity, which helps with data locality, while the i9-14901KE has a larger shared L3 pool for the entire processor.

Integrated graphics also differ. The i9-14901KE pairs with UHD Graphics 770, while the Core Ultra 5 235 uses Arc Xe-LPG Graphics with 24 execution units. The Core Ultra 5 235's graphics solution is based on newer architecture. Memory support diverges as well: the i9-14901KE accepts both DDR4 and DDR5 in dual-channel configuration, while the Core Ultra 5 235 is DDR5-only with a measured memory bandwidth of 102.4 GB/s. PCIe connectivity favors the Core Ultra 5 235, which provides Gen 5 with 20 lanes from the CPU, versus 16 lanes on the i9-14901KE.

Head-to-Head Benchmarks

Direct head-to-head benchmark comparisons between the two processors are not present in the database. However, the Core Ultra 5 235 has a full suite of recorded benchmark scores that define its performance envelope. The i9-14901KE has no recorded benchmark results, so numerical comparisons against it are impossible.

The Core Ultra 5 235's Cinebench scores show its multithreaded capability. In Cinebench R15 multicore, it scores 1488, with a single-core score of 210. In Cinebench R20, the multicore score jumps to 6202 with a single-core score of 875. The more demanding Cinebench R23 test yields a multicore score of 14769 and a single-core score of 2085. These results indicate a processor that scales well across increasing thread counts, though the lack of simultaneous multithreading means its 14 threads are physical cores only.

PassMark results for the Core Ultra 5 235 show strengths in specific workloads. Data compression scores 390711, while data encryption scores 29293. Extended instructions reach 32752, and floating-point math hits 117951. Integer math scores 87948, and the multithread test produces 37816. Physics processing scores 2570, and random string sorting reaches 48980. Single-thread performance is measured at 4516 in both PassMark single-thread tests. Prime number finding scores 371, which is a relatively modest result compared to the other math workloads.

The average benchmark score of 46062 places the Core Ultra 5 235 in a competitive position. Its nearest rival, the AMD Ryzen AI 9 HX 375, scores 46030, a delta of just 0.1% in favor of the AMD part. The Intel Core i9-13900HX scores 46098, putting it 0.1% ahead of the Core Ultra 5 235. The AMD EPYC 4364P and AMD EPYC 7303 both score 45970 and 45960 respectively, with deltas of 0.2% behind the Core Ultra 5 235. These margins are within noise, meaning the Core Ultra 5 235 performs essentially on par with these rivals across the aggregate benchmark suite.
