Intel Core 3 305 vs Intel Core i9-14900T Comparison

The Intel Core 3 305 and Intel Core i9-14900T represent opposite ends of Intel's current mobile and desktop design philosophies. The benchmark data shows a complete sweep for the Core i9-14900T across all 17 recorded tests, yet the two processors are engineered for entirely different physical environments. The Core 3 305 is a 15 W mobile part built on a 3 nm process, while the Core i9-14900T is a 35 W desktop processor on a 10 nm node. The average benchmark score of 51,015 for the Core i9-14900T places it in the 90th percentile of all CPUs, whereas the Core 3 305's average of 18,302 sits in the 72nd percentile. This gap, while substantial, masks the fact that the Core 3 305 competes directly with desktop processors like the Intel Core i3-14100, which shows a delta of -0.1%, indicating near-identical overall performance.

Where Each One Wins

The recorded benchmark results show no wins for the Intel Core 3 305 in any of the 17 head-to-head tests. The Intel Core i9-14900T wins every comparison, making the use-case distinction straightforward: the Core 3 305 is positioned for power-constrained mobile systems, while the Core i9-14900T is for desktop workloads that can use its 24 cores and 32 threads. The closest contest appears in PassMark single-thread tests, where the Core i9-14900T scores 4,016 against the Core 3 305's 3,977, a delta of only -1%. This near-parity in single-thread performance indicates that the mobile chip's 4.30 GHz boost clock is competitive for lightly threaded tasks, even against the desktop part's 5.50 GHz boost. The data suggests that for single-threaded applications, the Core 3 305 loses by a negligible margin, making the mobile part surprisingly capable in that specific workload category. The Core i9-14900T dominates heavily in multi-threaded and data-heavy workloads, such as PassMark integer math, where it scores 138,149 against 32,295, a delta of -76.6%. The Core 3 305's closest relative in the database, the AMD Ryzen 5 2600E, shows a delta of 0.4%, meaning the mobile chip slightly outperforms that older desktop processor in average score, despite being designed for a lower power envelope.

Architecture Differences

The architectural split between these two Intel processors is defined by process node, core configuration, and platform. The Core 3 305 uses the Wildcat Lake codename and is built on a 3 nm process, whereas the Core i9-14900T uses Raptor Lake-R on a 10 nm node. The Core 3 305 has 6 cores and 6 threads, while the Core i9-14900T has 24 cores and 32 threads, the latter featuring a hybrid configuration typical of Raptor Lake. The mobile part's cache hierarchy uses 192 KB of L1, 2.5 MB of L2, and 6 MB of shared L3. The desktop part lists 80 KB of L1 per core and 2 MB of L2 per core, with 36 MB of shared L3. The Core i9-14900T also has a die size of 257 mm², while the Core 3 305 has no recorded die size. The integrated graphics differ as well: the Core 3 305 uses Intel Xe3 Graphics with 1 Xe core, while the Core i9-14900T uses UHD Graphics 770. The Core 3 305 supports DDR5 and LPDDR5X memory in a single-channel configuration, while the Core i9-14900T supports both DDR4 and DDR5 in dual-channel mode. The memory bandwidth for the Core 3 305 is recorded at 59.7 GB/s, while the Core i9-14900T has no recorded memory bandwidth figure. PCIe support also differs, with the Core 3 305 using Gen 4 with 6 CPU lanes, and the Core i9-14900T using Gen 5 with 16 CPU lanes. ECC memory is supported on the Core i9-14900T but not on the Core 3 305.
