Intel Core i3-9300 vs Intel Core i7-10610U Comparison

Head-to-Head Benchmarks

The benchmark data paints a remarkably consistent picture: the Intel Core i7-10610U wins every single recorded comparison against the Intel Core i3-9300. Across all six Cinebench tests, the mobile i7 holds a narrow but uniform advantage, with delta percentages ranging from -3.5% to -3.8% in favor of the i7-10610U.

In Cinebench R15 multi-core, the i7-10610U scores 561 against the i3-9300's 541, a 3.6% lead. The single-core R15 test shows a similar margin: 79 versus 76, a 3.8% advantage. Moving to Cinebench R20, the i7-10610U posts 2338 multi-core and 330 single-core, while the i3-9300 manages 2257 and 318 respectively, translating to 3.5% and 3.6% leads for the mobile part.

The newest test in the set, Cinebench R23, repeats the pattern. The i7-10610U scores 5569 multi-core and 786 single-core, versus 5374 and 758 for the i3-9300. That is a 3.5% multi-core win and a 3.6% single-core win for the i7-10610U. The consistency is striking: no test deviates far from the 3.5% to 3.8% band, suggesting the performance gap is structural rather than workload-specific.

The average benchmark score amplifies the difference. The i3-9300 averages 1554 across its benchmark set, placing it in the 39th percentile of all CPUs. The i7-10610U averages 1611, also in the 39th percentile. The raw delta between their average scores is roughly 3.7%, which aligns with the individual test deltas.

For context, the i3-9300's nearest rivals include the Intel Xeon E3-1268L v5 at 1557 (0.2% ahead), the AMD FX-8350 at 1557 (0.2% ahead), the Intel Core i5-4690S at 1551 (0.2% behind), and the Intel Core i3-1115G4E at 1559 (0.3% ahead). The i7-10610U's nearest rivals include the Intel Core i7-970 at 1613 (0.1% ahead), the Intel Core i3-9100T at 1620 (0.6% ahead), the Intel Xeon E3-1240L v5 at 1609 (0.1% behind), and the Intel Core i3-9100E at 1605 (0.4% behind). These rival clusters show that both chips sit within a tightly packed performance band, but the i7-10610U occupies a slightly higher tier.

Architecture Differences

Both processors are built on Intel's 14 nm process node and share the same core configuration in terms of physical cores: four cores each. The cache hierarchy is identical in structure, with 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 8 MB of shared L3 cache. The fundamental architectural split comes down to threading, socket, and platform positioning.

The i3-9300 is a desktop part built on the Coffee Lake architecture, specifically the Coffee Lake Refresh generation. It runs 4 threads across its 4 cores, meaning no Hyper-Threading. Its base clock is 3.70 GHz and it boosts to 4.30 GHz. The chip uses the Intel Socket 1151 and has a thermal design power (TDP) of 62 watts. Its die size is 126 mm². It supports DDR4 memory in dual-channel configuration with a recorded memory bandwidth of 38.4 GB/s. It also supports ECC memory, a feature not present on the mobile rival. The integrated graphics are UHD 630. The PCIe implementation is Gen 3 with 16 lanes available from the CPU. It launched in April 2019 with a launch MSRP of $143.

The i7-10610U is a mobile part built on the Comet Lake architecture, specifically Comet Lake-U. It runs 8 threads across its 4 cores, enabled by Hyper-Threading. Its base clock is 1800.00 MHz and it boosts to 4.90 GHz. The chip uses the Intel BGA 1440 socket and has a TDP of 25 watts, less than half that of the desktop i3. It supports both DDR3 and DDR4 memory in dual-channel configuration; no memory bandwidth figure is recorded for this part. ECC memory is not supported. The integrated graphics are listed as UHD Graphics. The PCIe implementation is Gen 3 without a specific lane count listed. It launched in April 2020, roughly a year after the i3-9300.

The most consequential architectural difference is threading. The i7-10610U's 8 threads versus the i3-9300's 4 threads explains why the mobile chip wins multi-core tests despite its much lower base clock and TDP envelope. The boost clock tells the story for single-core: the i7-10610U's 4.90 GHz peak exceeds the i3-9300's 4.30 GHz, which explains the consistent single-core advantage.

The TDP difference is also notable. The i7-10610U is rated at 25 watts versus 62 watts for the i3-9300. This does not appear in benchmark scores directly, but it frames the comparison: the mobile chip delivers higher measured performance while being designed for a far more constrained thermal and power environment.

Where Each One Wins

The benchmark results give the i7-10610U a clean sweep across every recorded test. There are no wins for the i3-9300 in the head-to-head data. That said, the context matters for interpreting these wins.

The i7-10610U wins in every multi-core test: R15 at 561 versus 541, R20 at 2338 versus 2257, and R23 at 5569 versus 5374. The margins are consistent at roughly 3.5%. This is a direct consequence of the threading advantage: 8 threads against 4 threads allows the mobile chip to extract more parallel throughput in Cinebench's rendering workloads, even with a much lower base clock.

The single-core tests also favor the i7-10610U: R15 at 79 versus 76, R20 at 330 versus 318, and R23 at 786 versus 758. The margins here are between 3.6% and 3.8%. This aligns with the boost clock advantage: 4.90 GHz versus 4.30 GHz. The i7-10610U's higher peak frequency gives it a clear edge in lightly threaded workloads.

For the i3-9300, the case is not about winning benchmarks but about where its characteristics are preferable. It is a desktop part with a 62 watt TDP, which means it is designed for systems with active cooling and a power supply. It supports ECC memory, which is relevant for certain workstation or server-adjacent use cases. It uses the LGA 1151 socket, which allows for socketed installation and potential upgrades. It also has a recorded memory bandwidth of 38.4 GB/s, a figure not available for the i7-10610U.

For the i7-10610U, its wins translate to real-world advantages in both multi-threaded productivity and single-threaded responsiveness. The 25 watt TDP makes it suitable for thin-and-light laptops, where the i3-9300's 62 watt desktop envelope would be impractical. The BGA 1440 socket means it is soldered to the motherboard, which is typical for mobile platforms.

The Verdict

The data is unambiguous: the Intel Core i7-10610U outperforms the Intel Core i3-9300 in every recorded benchmark. The single-core advantage is driven by a higher boost clock (4.90 GHz versus 4.30 GHz). The multi-core advantage is driven by Hyper-Threading, which doubles the thread count from 4 to 8. The i7-10610U achieves this with a TDP of 25 watts versus 62 watts, making it the more efficient performer by a wide margin.

Buyers should choose the i7-10610U if they need the best measured performance in Cinebench workloads and are operating within a mobile platform. The 8-thread configuration provides a meaningful uplift in multi-core rendering, and the higher boost clock delivers faster single-core results. The 25 watt TDP makes it suitable for laptops and compact systems where thermal headroom is limited.

Buyers should choose the i3-9300 if they require a socketed desktop processor with ECC memory support. The LGA 1151 platform allows for conventional desktop installation and upgrade paths. The 62 watt TDP is higher, but that is appropriate for desktop chassis with dedicated cooling. The memory bandwidth figure of 38.4 GB/s is recorded for this part, which may matter for memory-intensive workloads.

The percentile rankings do not differentiate the two: both sit at the 39th percentile of all CPUs. The average benchmark scores place them in neighboring performance tiers, with the i7-10610U at 1611 and the i3-9300 at 1554. The nearest rival clusters confirm this: the i3-9300 trades blows with Xeon E3-1268L v5, FX-8350, i5-4690S, and i3-1115G4E, while the i7-10610U sits alongside i7-970, i3-9100T, Xeon E3-1240L v5, and i3-9100E.

In short, the i7-10610U is the faster chip in every measured dimension. The i3-9300 offers platform features that the mobile chip cannot match, specifically ECC support and a socketed form factor, but in raw benchmark performance, it loses across the board.
