Intel Core i7-10510U vs Intel Core i9-13900E Comparison

The Intel Core i9-13900E and Intel Core i7-10510U occupy opposite ends of Intel’s product stack, and the benchmark data reflects a complete mismatch in compute capability. The i9-13900E, a desktop Raptor Lake part, holds an 8-0 win record across all head-to-head tests, with the widest margins appearing in multi-threaded workloads. In Cinebench R23 multi-core, the i9-13900E scores 34,244 against the i7-10510U’s 5,388, a delta of 535.6%. The single-core gap is almost as stark: 4,834 versus 760 in Cinebench R23, a 536.1% difference. These are not incremental improvements; they represent a generational and architectural chasm.

Head-to-Head Benchmarks

The most lopsided results come from Cinebench’s multi-core tests, where the i9-13900E’s 24 cores and 32 threads overwhelm the i7-10510U’s 4 cores and 8 threads. In Cinebench R20 multi-core, the i9-13900E posts 14,382, while the i7-10510U manages 2,262, a 535.8% advantage. The pattern repeats in Cinebench R15 multi-core, with scores of 3,451 and 542, respectively, a 536.7% delta. Even the single-core tests, which typically narrow the gap between processors of different core counts, show massive leads: 487 versus 76 in Cinebench R15 single-core (540.8%), and 2,030 versus 319 in Cinebench R20 single-core (536.4%).

Geekbench results tell a slightly different story, though the winner remains unchanged. In Geekbench multi-core, the i9-13900E scores 8,337 against the i7-10510U’s 2,648, a 214.8% delta—large but proportionally smaller than the Cinebench margins. The single-core Geekbench test shows the closest relative result of the entire comparison, with the i9-13900E at 1,646 and the i7-10510U at 1,032, a 59.5% lead. This narrower gap suggests that while the i9-13900E’s higher boost clock of 5.20 GHz helps, the i7-10510U’s 4.90 GHz boost is not far behind in nominal clock speed. The real separation comes from IPC improvements and core count, not raw frequency.

Where Each One Wins

Given the 8-0 sweep, the i9-13900E wins every category where both chips have benchmark data. Its dominance is most pronounced in heavily parallel workloads: Cinebench R23 multi-core, Cinebench R20 multi-core, and Cinebench R15 multi-core all show deltas above 535%. These tests scale with core count and memory bandwidth, areas where the i9-13900E’s 36 MB of shared L3 cache and dual-channel DDR5 support provide a structural advantage. The i7-10510U, with 8 MB of shared L3 cache and DDR3/DDR4 support, cannot compete in sustained multi-threaded rendering or simulation tasks.

The i7-10510U’s only "win" is in the field of power efficiency, though the FACT PACK does not include direct power draw measurements. Its 25 W TDP versus the i9-13900E’s 65 W TDP suggests the mobile chip consumes far less energy, making it better suited for battery-powered devices. The i7-10510U also has additional PassMark benchmarks not present for the i9-13900E, including data compression (82,606), data encryption (2,151), and integer math (23,441). These scores are not comparable to the i9-13900E, but they indicate the i7-10510U is a capable processor for light productivity tasks where the i9-13900E would be overkill.

Architecture Differences

The two processors are separated by four generations of Intel architecture. The i9-13900E uses Raptor Lake, built on a 10 nm process at Intel’s foundry, while the i7-10510U uses Comet Lake, a 14 nm design. This process difference explains much of the performance gap: the 10 nm node allows for higher transistor density and better power efficiency, enabling the i9-13900E to pack 24 cores into a 257 mm² die. The i7-10510U’s die size is not listed, but its 4-core configuration on 14 nm would be substantially smaller in core count if not necessarily in physical size.

Cache hierarchies differ dramatically. The i9-13900E features 80 KB of L1 cache per core and 2 MB of L2 cache per core, with 36 MB of shared L3. The i7-10510U has 64 KB of L1 per core, 256 KB of L2 per core, and only 8 MB of shared L3. The i9-13900E’s larger cache reduces memory latency and improves data throughput, particularly in workloads that repeatedly access the same data sets. Memory support also diverges: the i9-13900E supports DDR4 and DDR5, while the i7-10510U supports DDR3 and DDR4. The i9-13900E also adds ECC memory support, a feature absent on the i7-10510U.

PCIe connectivity is another differentiator. The i9-13900E offers PCIe Gen 5 with 16 CPU lanes, enabling faster NVMe storage and graphics cards. The i7-10510U’s PCIe capabilities are not listed, but as a mobile part from 2019, it would be limited to older PCIe generations. Integrated graphics differ as well: the i9-13900E ships with UHD Graphics 770, while the i7-10510U has a generic UHD Graphics solution. The socket types are incompatible—Intel Socket 1700 for the i9-13900E versus Intel BGA 1440 for the i7-10510U—meaning they cannot be swapped between systems.

The Verdict

The data clearly shows the i9-13900E is the superior processor in every measured benchmark. Its Cinebench R23 multi-core score of 34,244 is 535.6% higher than the i7-10510U’s 5,388, and its Geekbench single-core score of 1,646 is 59.5% higher. For users running CPU-intensive desktop workloads—video rendering, 3D modeling, scientific simulations—the i9-13900E is the only rational choice. Its 24 cores, 32 threads, and 36 MB of L3 cache provide a level of parallel performance that the i7-10510U cannot approach.

The i7-10510U, however, is not without merit. Its 25 W TDP and mobile BGA 1440 socket make it suitable for laptops and compact devices where power draw and heat dissipation are primary concerns. Its PassMark scores, while not directly comparable to the i9-13900E, show it can handle everyday tasks like data compression and encryption. But for anyone who needs maximum compute performance, the i9-13900E wins outright. The i7-10510U is an end-of-life product, while the i9-13900E remains active in production. The verdict is unambiguous: the i9-13900E for performance, and the i7-10510U only if the use case demands a low-power mobile chip.
