AMD Ryzen Threadripper 3960X vs Intel Core i5-10300H Comparison

The AMD Ryzen Threadripper 3960X and Intel Core i5-10300H occupy opposite ends of the computing spectrum, yet their average benchmark scores are nearly identical. The Threadripper 3960X averages 9284, while the i5-10300H averages 9243, a difference of just 0.4%. This parity in aggregate scores, however, masks a complete divergence in workload characteristics: the Threadripper wins all 14 head-to-head benchmark comparisons, while the i5-10300H wins none. The data tells a story of two processors that achieve similar average numbers through entirely different means—one through massive multi-threaded throughput, the other through efficiency and mobility.

Head-to-Head Benchmarks

The Threadripper 3960X dominates every benchmark in the comparison, but the margins vary wildly depending on thread count. In single-threaded tests, the gap is narrow: the Threadripper scores 725 in 3DMark single-thread versus 705 for the i5-10300H, a 2.8% edge. The Geekbench single-core result shows a larger 27.3% advantage for the Threadripper (1681 vs 1321).

The real separation appears as thread counts scale. In 3DMark 2-thread, the Threadripper leads by just 7.4% (1436 vs 1337). At 4 threads, the lead grows to 26% (2775 vs 2202). By 8 threads, the Threadripper is 78.1% ahead (5267 vs 2957). The 16-thread test shows a 236.9% advantage (9989 vs 2965), and at max threads, the Threadripper's 13978 score is 372.1% higher than the i5-10300H's 2961.

Cinebench results amplify the multi-core gap even further. In Cinebench R15 multi-core, the Threadripper scores 4692 versus 700, a 570.3% advantage. The single-core R15 test shows a 575.5% lead (662 vs 98), which is surprising given the smaller single-thread differences elsewhere. Cinebench R20 and R23 both show identical 569.9% deltas in favor of the Threadripper, for both single-core and multi-core runs. The R20 multi-core score is 19553 vs 2919, and R23 multi-core is 46557 vs 6950.

Geekbench multi-core shows a 226.6% advantage (13326 vs 4080). The pattern is consistent: the Threadripper's 24 cores and 48 threads overwhelm the i5-10300H's 4 cores and 8 threads in every scaled workload. The 3DMark max-thread result is particularly illustrative, with the Threadripper delivering 13978 points—nearly five times the i5-10300H's 2961.

Architecture Differences

The fundamental architectural divide is core count. The Threadripper 3960X packs 24 cores and 48 threads, while the i5-10300H offers 4 cores and 8 threads. Both processors boost to 4.50 GHz, but the base clocks differ substantially: the Threadripper runs at 3.80 GHz versus 2.50 GHz for the Intel part.

Process technology separates them further. The Threadripper uses TSMC's 7 nm process with a Zen 2 architecture (codename Castle Peak), while the i5-10300H uses Intel's 14 nm process with Comet Lake architecture (codename Comet Lake-H). The Threadripper's die consists of 4x 74 mm² chiplets with 15,200 million transistors, whereas the Intel part has no listed transistor count or die size.

Cache configurations reflect the different design philosophies. Both share 64 KB L1 per core, but the Threadripper has 512 KB L2 per core versus 256 KB for the i5-10300H. The L3 cache is the starkest difference: 128 MB on the Threadripper versus 6 MB (shared) on the i5-10300H.

Memory architecture differs completely. The Threadripper supports DDR4 in quad-channel configuration with 102.4 GB/s bandwidth. The i5-10300H supports both DDR3 and DDR4 in dual-channel, yielding only 46.9 GB/s. The Threadripper uses PCIe Gen 4, while the Intel part uses Gen 3. The i5-10300H includes integrated UHD Graphics; the Threadripper has none.

The Verdict

The benchmark data is unambiguous: the AMD Ryzen Threadripper 3960X is the superior processor in every measured category. It wins all 14 head-to-head benchmarks, including every single-thread test, which is notable given that both processors share a 4.50 GHz boost clock. The Threadripper's 24 cores and 48 threads deliver 570.3% higher Cinebench R15 multi-core scores and 372.1% higher 3DMark max-thread scores than the i5-10300H.

The i5-10300H's only claim to relevance is its aggregate score parity, which stems from its mobile efficiency. Its 45 W TDP and integrated UHD Graphics make it suitable for laptops, while the Threadripper's 280 W TDP and lack of integrated graphics demand a desktop platform with a discrete GPU. The Intel part also supports DDR3 memory, offering flexibility in older systems.

For anyone building a desktop workstation or high-performance computing rig, the Threadripper 3960X is the clear choice. Its 128 MB L3 cache, quad-channel memory, and PCIe Gen 4 support provide a platform for heavy multi-threaded workloads. The i5-10300H, conversely, is a mobile processor with no desktop equivalent in this comparison. The 4-core, 8-thread configuration and dual-channel memory cap its performance ceiling, though its lower power draw suits portable systems.

Where Each One Wins

The Threadripper 3960X wins in every benchmark category, but the margins define its strengths. In 3DMark tests, the advantage grows from 2.8% at single-thread to 372.1% at max threads, indicating that the Threadripper's scaling is exceptional. Cinebench results show a consistent 569.9-575.5% lead across all tests, making it the definitive choice for rendering and 3D modeling workloads. Geekbench multi-core shows a 226.6% advantage, confirming its dominance in general multi-threaded applications.

The i5-10300H does not win any benchmarks, but its profile suggests specific use cases. Its 45 W TDP makes it viable for thin-and-light laptops where the Threadripper's 280 W TDP is impossible. The integrated UHD Graphics eliminates the need for a discrete GPU in basic systems. Its support for both DDR3 and DDR4 memory allows it to fit into existing motherboard ecosystems. The 4-core design with a 4.50 GHz boost clock provides adequate performance for light productivity tasks, though the data shows it trails the Threadripper by 27.3% even in Geekbench single-core.

In practice, these processors serve entirely different markets. The Threadripper 3960X is a desktop part for professionals who need maximum throughput—its 48 threads and 128 MB cache excel at video encoding, scientific computing, and virtual machines. The i5-10300H is a mobile part for users who prioritize portability and power efficiency over raw performance. The benchmark scores confirm that while the Threadripper is the performance king, the i5-10300H's niche is mobility, not speed.
