About Intel Core i3-N305

The Intel Core i3-N305 is a mobile processor built on Intel’s Gracemont architecture, released on 2023-01-02 with a launch MSRP of $309. It has 8 cores and 8 threads, a 3.80 GHz boost clock, integrated UHD Graphics 770, and a 15 W TDP. The benchmark database places it at the 50th percentile among all CPUs, with an average score of 2376. Its nearest rivals are separated from it by deltaPct values of +0.4, -0.4, +0.7, and -0.9, making this an unusually tight cluster of mid-pack results.

Benchmark Performance

The i3-N305’s Cinebench results show a consistent mid-range position. In Cinebench R15, it scores 828 multi-core and 116 single-core. In Cinebench R20, it scores 3450 multi-core and 487 single-core. In Cinebench R23, it scores 8216 multi-core and 1160 single-core. The single-core scores are modest in absolute terms, while the multi-core scores benefit from the 8-core, 8-thread configuration.

The aggregate picture is defined by the average benchmark score of 2376 and the 50th percentile ranking. Against its four nearest rivals, the margins are very small. The i3-N305 sits 0.4% above the AMD Ryzen 3 5300U’s average score of 2367, and 0.7% above the AMD Ryzen 5 2500X’s average score of 2361. It sits 0.4% below the Intel Core i5-1155G7’s 2387 and 0.9% below the Intel Core i5-8600T’s 2398. The largest gap in this group is the 0.9% delta with the i5-8600T, which is still a narrow margin.

What this means in practice is that the benchmark results place the i3-N305 in the middle of the current CPU distribution. It is not a high-end performer, but it is also not far off several established processors. The Cinebench multi-core numbers, especially the R23 score of 8216, show that the chip can carry parallel workloads without collapsing into the low end of the database.

Who Should Consider It

For everyday office use, the single-core scores are the relevant part of the data. The Cinebench R15 single-core score of 116, the R20 score of 487, and the R23 score of 1160 indicate a processor that handles common single-threaded desktop tasks without the need for especially high sustained clock speeds. The 15 W TDP and mobile segment further suggest a machine designed around portability and quiet operation.

For content creation, the multi-core scores are more useful. The Cinebench R23 multi-core score of 8216 and the R20 multi-core score of 3450 show meaningful parallel throughput from the 8 cores. This makes the processor a plausible fit for occasional Cinebench-style rendering or other multi-threaded creation tasks on a thin-and-light mobile system. It is not a creator flagship; the 50th percentile ranking makes that clear. But within its power class, the multi-core results are much stronger than the single-core results.

For gaming, the data is limited. The processor has a 3.80 GHz boost clock and integrated UHD Graphics 770, but no gaming benchmark appears in the fact pack. Buyers should treat gaming conclusions as unproven from this database. The CPU side of the chip is capable in aggregate, but the integrated GPU is the graphics path, and no game scores are available to quantify it.

Platform and Compatibility

The i3-N305 uses Socket Intel BGA 1264 and belongs to the Core i3 (Alder Lake-N) generation. It is fabricated on Intel’s 10 nm process node. The cache hierarchy is structured as 96 KB of L1 per core, 2 MB of L2 per module, and 6 MB of shared L3.

Memory support includes DDR4 and DDR5 over a single-channel memory bus, with a memory bandwidth of 38.4 GB/s. ECC memory is not supported. The processor provides PCIe Gen 3 with 9 lanes, CPU only. Integrated graphics is UHD Graphics 770. The integrated GPU removes the need for a separate display adapter in basic configurations.

The platform is explicitly a mobile design: the market segment is Mobile, the production status is Active, and the part number is SRMDQ. The multiplier is not unlocked, so user-controlled overclocking is not supported. The BGA 1264 socket indicates a board-mounted mobile package, which means platform compatibility is fixed at the time the board is chosen rather than through a desktop-style socketed upgrade. The combination of single-channel memory, 9 PCIe lanes, and no ECC makes this platform more suited to compact mainstream laptops than to high-expansion workstation builds.

Power and Thermals

The i3-N305 has a TDP of 15 W, which places it in the low-power mobile tier. This is a small power envelope for an 8-core processor, and the thermal implications are modest. A low-power mobile design does not require the kind of cooling solution associated with desktop high-core-count parts. The 10 nm process node is consistent with a compact, efficient platform.

The integrated UHD Graphics 770 shares the same package, so the thermal load includes both CPU and GPU on one die. The 3.80 GHz boost clock is the headline frequency, but the processor remains within the 15 W class. For system builders, the data indicates that the cooling priority is chassis airflow and quiet operation rather than high-capacity heatsinks. The 50th percentile average score, combined with 15 W power, suggests a predictable thermal profile rather than an extreme one.

Single-Thread vs Multi-Thread Behavior

The Cinebench results reveal a clear split between single-thread and multi-thread performance. In Cinebench R15, the single-core score is 116 and the multi-core score is 828. In Cinebench R20, the single-core score is 487 and the multi-core score is 3450. In Cinebench R23, the single-core score is 1160 and the multi-core score is 8216.

The multi-core scores are far above the single-core scores, which reflects the 8-core, 8-thread configuration. Workloads that can use all cores will extract a much higher result than workloads limited to one core. Single-threaded applications, by contrast, will rely on the lower single-core scores and the 3.80 GHz boost clock. This makes the processor well matched to mixed-use mobile systems where users alternate between light single-threaded tasks and parallel creation workloads. The data does not show single-core dominance; it shows a core-count-driven multi-core advantage within a low-power envelope.

How It Compares

Compared with the AMD Ryzen 3 5300U, the i3-N305 has an average score of 2376 against 2367, with a deltaPct of +0.4. That is effectively a tie. The N305 is slightly ahead, but the margin is small enough that benchmark position is not distinguishable from parity.

Compared with the Intel Core i5-1155G7, the i3-N305 is behind. The i5-1155G7 averages 2387, while the N305 averages 2376, a deltaPct of -0.4. Again, the gap is tiny; the ranking is essentially the same performance class.

Compared with the AMD Ryzen 5 2500X, the i3-N305 is ahead by a deltaPct of +0.7, with the Ryzen 5 2500X averaging 2361. The N305’s higher average score is still within a narrow band, but the direction of the comparison favors the Intel part.

Compared with the Intel Core i5-8600T, the i3-N305 trails by the largest margin among the listed rivals. The i5-8600T averages 2398, and the deltaPct is -0.9. Even the biggest competitor gap in this group is under a full point, so the overall conclusion is that the i3-N305 sits in a very tight mid-pack cluster.
