Architecture Differences

The two processors come from different architectural lineages. The i9-14901E uses Raptor Lake architecture, specifically the Raptor Lake-R codename, built on Intel's 10 nm process at Intel's own foundry. The Ultra 7 258V uses Lunar Lake architecture, built on TSMC's 3 nm process. This process difference explains much of the power and efficiency gap: the Ultra 7 258V has a 17 watt TDP, while the i9-14901E has a 65 watt TDP.

The core counts are identical at 8 cores each, but the threading models differ. The i9-14901E supports 16 threads, meaning it has simultaneous multithreading enabled. The Ultra 7 258V supports only 8 threads, one per core, with no SMT. This directly explains many of the multicore benchmark gaps.

Cache structures differ significantly. The i9-14901E has 80 KB of L1 cache per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The Ultra 7 258V has 192 KB of L1 per core, 2.5 MB of L2 per core, but only 12 MB of shared L3. The larger L3 on the desktop part, combined with the larger thread count, gives the i9-14901E a substantial advantage in cache-heavy workloads like data compression and random string sorting.

The memory interfaces also differ. The i9-14901E supports DDR4 and DDR5 memory in a dual-channel configuration, while the Ultra 7 258V supports LPDDR5X with a memory bandwidth of 136.5 GB/s. The Ultra 7 258V also uses a different socket, Intel BGA 2833, which is a mobile package, versus the i9-14901E's Intel Socket 1700 desktop socket.

PCIe support differs as well: the i9-14901E provides Gen 5 with 16 lanes from the CPU, while the Ultra 7 258V provides Gen 5 with only 4 lanes. This makes the desktop part far more suitable for multiple high-bandwidth expansion cards.

Where Each One Wins

The i9-14901E wins every recorded benchmark category, so the data does not show any workload where the Ultra 7 258V takes the lead. However, the margin of victory varies, and that variation tells a useful story.

For heavily multithreaded workloads like Cinebench R23 multicore rendering, the i9-14901E delivers a 150% advantage. This is the single largest gap in the data and makes the desktop part the obvious choice for users running 3D rendering, video encoding, or any workload that scales across many threads. The 16-thread support versus 8 threads is the primary driver here.

For integer-heavy workloads, the i9-14901E shows a 162.9% delta in PassMark integer math. This suggests the desktop part handles compiled code, scripting, and general application logic substantially faster. The 36 MB L3 cache helps with data-heavy integer workloads, as seen in the 81.4% delta in random string sorting and the 63.4% delta in data compression.

For single-threaded tasks, the i9-14901E still wins, but by a smaller margin. The PassMark single-thread delta is 8.4%, and the Cinebench R15 single-core delta is 28.4%. The find prime numbers test is nearly a tie at 2.2%. This indicates that the Ultra 7 258V's Lunar Lake cores are relatively strong per-clock, but the i9-14901E's higher boost clock (5.60 GHz versus 4.80 GHz) still gives it the edge.

The Ultra 7 258V's wins are not in raw performance but in efficiency and form factor. Its 17 watt TDP versus 65 watts, combined with a mobile BGA package, makes it suitable for thin-and-light laptops. The 136.5 GB/s memory bandwidth from LPDDR5X is a highlight for memory-intensive mobile workloads. The Arc 140V integrated graphics is a different class of iGPU compared to the UHD Graphics 770 on the desktop part, which matters for users who need strong integrated graphics in a low-power mobile system.

Users choosing between these parts should base the decision on platform and power constraints. The i9-14901E is a desktop processor with a 65 watt TDP, Socket 1700, and 16 PCIe Gen 5 lanes, designed for full-sized systems with dedicated expansion. The Ultra 7 258V is a mobile processor with a 17 watt TDP, BGA 2833, and 4 PCIe Gen 5 lanes, designed for portable systems where battery life and thermals take priority over raw throughput. The benchmark data shows no performance scenario where the mobile part overtakes the desktop part, but the two serve fundamentally different use cases.
