Intel Core i7-14701E vs Intel Core Ultra 9 288V Comparison

The Verdict

The recorded data separates these two processors clearly by workload class. The Intel Core i7-14701E wins 16 of 17 head-to-head benchmark comparisons, with an average benchmark score of 33206 against 23219 for the Intel Core Ultra 9 288V. The i7-14701E also holds the higher percentile rank, sitting at 83 versus 76 for the Ultra 9 288V. The single benchmark victory for the Ultra 9 288V comes in the PassMark find prime numbers test, where it scores 195 against 176, a 9.7% advantage.

The i7-14701E is the processor for multi-threaded desktop workloads. Its Cinebench R23 multicore score of 22195 more than doubles the 10178 of the Ultra 9 288V, a 118.1% gap that represents the largest delta in the entire comparison. The Ultra 9 288V, by contrast, is a mobile part with a 30 TDP and a smaller L3 cache, and the data shows it is not competitive in sustained parallel tasks. The verdict from the measurements: choose the i7-14701E for compute-heavy desktop builds, while the Ultra 9 288V only makes sense where its mobile form factor and lower power envelope are the primary constraints.

Architecture Differences

The two processors come from different Intel families and different foundries. The i7-14701E is built on Raptor Lake architecture, specifically the Raptor Lake-R codename, on a 10 nm process node fabricated by Intel. The Ultra 9 288V uses Lunar Lake architecture on a 3 nm node fabricated by TSMC. The process node difference is substantial, and it explains part of the power and thermal gap: the i7-14701E has a 65 TDP while the Ultra 9 288V draws 30.

Core counts are identical at 8, but thread counts differ. The i7-14701E supports 16 threads, indicating simultaneous multithreading, while the Ultra 9 288V supports 8 threads, one per core. The cache hierarchy also diverges. The i7-14701E has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. The Ultra 9 288V has 192 KB of L1 per core, 2.5 MB of L2 per core, and only 12 MB of shared L3. The larger L3 on the desktop part is a major factor in its multicore dominance.

Memory support differs completely. The i7-14701E accepts DDR4 and DDR5 in a dual-channel configuration, while the Ultra 9 288V is limited to LPDDR5X with a measured memory bandwidth of 136.5 GB/s. ECC memory is supported on the i7-14701E but not on the Ultra 9 288V. The desktop part also exposes more PCIe connectivity, with Gen 5, 16 lanes from the CPU, whereas the mobile part offers Gen 5, 4 lanes from the CPU. Integrated graphics differ as well: the i7-14701E uses UHD Graphics 770, the Ultra 9 288V uses Arc 140V. The socket situation is another divider, with the i7-14701E on Intel Socket 1700 and the Ultra 9 288V on Intel BGA 2833, a soldered mobile package.

Head-to-Head Benchmarks

The Cinebench suite shows the clearest separation. In Cinebench R15 multicore, the i7-14701E scores 2237 against 1583, a 41.3% lead. The R15 single-core result is closer, 315 versus 301.5, a 4.5% edge for the desktop chip. Cinebench R20 widens the gap substantially: multicore shows 9321 versus 7069 (31.9% ahead), and single-core shows 1315 versus 997, also 31.9% ahead. The R23 results are the most dramatic. Multicore gives 22195 versus 10178, a 118.1% advantage. Single-core gives 3133 versus 1950, a 60.7% advantage. The single-core R23 delta is notable because it shows the desktop part is not merely winning on thread count; its per-thread performance is also significantly higher in this test.

PassMark results follow a similar pattern, though with some variation. Data compression scores 282939 versus 186521, a 51.7% lead. Integer math shows 81325 versus 44019, an 84.7% lead, the second-largest delta in the comparison. Multithread scores 26112 versus 19810, a 31.8% lead. Physics scores 2399 versus 1637, a 46.5% lead. Random string sorting scores 29158 versus 22622, a 28.9% lead. Extended instructions score 18528 versus 15613, an 18.7% lead. Data encryption is a narrow win at 14862 versus 14141, only 5.1% ahead. Floating point math is also close, 61873 versus 59536, a 3.9% margin. Single-thread PassMark is nearly tied: 4305 versus 4274, a 0.7% edge.

The one reversal is prime number finding. The Ultra 9 288V scores 195 against 176, a 9.7% win. This is an isolated result, but it appears consistently in the data as the only test where the mobile chip outpaces the desktop chip. The nearest rival data places the i7-14701E alongside desktop and mobile parts like the AMD Ryzen 9 PRO 6950H (33201, 0% delta), AMD Ryzen 5 8645HS (33244, -0.1%), AMD Ryzen 7 7745HX (33091, 0.3%), and Intel Core i7-13650HX (33089, 0.4%). The Ultra 9 288V sits near the Intel Core i9-11900F (23254, -0.2%), AMD EPYC 4124P (23167, 0.2%), AMD Ryzen 7 5800H (23277, -0.2%), and Intel Core Ultra 7 266V (23297, -0.3%).

Where Each One Wins

The i7-14701E dominates in nearly every measured category. Its wins span Cinebench R15, R20, and R23 in both single-core and multicore tests. It wins all PassMark workloads except prime number finding. The data suggests the desktop part is the stronger choice for integer math, data compression, multithreaded rendering, physics simulation, string sorting, extended instruction workloads, encryption, and floating point math. The Cinebench R23 multicore result, at 118.1% ahead, makes the i7-14701E the clear pick for any application that scales across threads.

The Ultra 9 288V wins only the prime number test. That result, 195 versus 176, indicates a specific advantage in a workload that may benefit from its lower-latency memory or architecture characteristics. But the win is narrow in absolute terms, and it does not offset the losses elsewhere. The Ultra 9 288V also carries a 30 TDP versus 65 for the i7-14701E, which positions it for a different physical environment, and its LPDDR5X memory support with 136.5 GB/s bandwidth is tailored to mobile integration. The use-case split is therefore not about raw performance, where the i7-14701E wins decisively, but about platform: the i7-14701E is for desktop sockets with expandable memory, the Ultra 9 288V is for compact mobile systems.
