AMD Ryzen Threadripper 3990X vs Intel Core i7-10750H Comparison

The benchmark data presents a stark contrast between a mobile six-core processor and a desktop sixty-four-core workstation flagship. The AMD Ryzen Threadripper 3990X dominates almost every metric, with the Intel Core i7-10750H securing a single victory in a low-thread-count test. The data shows the Threadripper 3990X is in a completely different performance class, while the i7-10750H is optimized for a power-constrained environment.

Head-to-Head Benchmarks

The scale of the Threadripper 3990X’s victory is most visible in multi-threaded workloads. In Cinebench R23 multi-core, the AMD processor scores 68,124 against the Intel’s 9,718, a delta of -85.7%. This pattern repeats across every Cinebench iteration: R15 multi-core shows 6,866 versus 979 (-85.7%), and R20 multi-core shows 28,612 versus 4,081 (-85.7%). The Geekbench multi-core test tells the same story, with the Threadripper 3990X scoring 20,912 against 5,574, a -73.3% difference.

The 3DMark results further illustrate the thread-count advantage. At 16 threads, the AMD chip scores 9,975 versus 4,162 (-58.3%). Expanding to max threads, the gap widens dramatically: 18,441 versus 4,186, marking a -77.3% delta. The Intel processor’s performance plateaus at 4,186 in the max-thread test, while the AMD part scales to over four times that score, demonstrating the benefit of its 128 threads.

Single-thread performance is the only area where the Intel part shows any competitive edge. In the 3DMark single-thread test, the i7-10750H scores 728 versus 695, a 4.7% advantage. This is the sole benchmark win for Intel out of 14 head-to-head comparisons. However, in Cinebench R15, R20, and R23 single-core tests, the AMD part wins decisively. For instance, Cinebench R23 single-core shows 9,617 for AMD versus 1,372 for Intel (-85.7%), and Geekbench single-core shows 1,472 versus 1,417 (-3.7%).

The Cinebench single-core results are particularly notable. The Intel Core i7-10750H has a higher boost clock (5.00 GHz versus 4.30 GHz), yet it trails in every Cinebench single-core test. The Threadripper 3990X’s 7 nm process and Zen 2 architecture appear to deliver superior instructions-per-clock, outscoring the Intel part despite its lower clock speed. The data indicates that the Intel part’s 5.00 GHz boost is insufficient to overcome the architectural efficiency of the AMD design.

Architecture Differences

The two processors are built on fundamentally different architectures. The Intel Core i7-10750H is a 14 nm Comet Lake-H part with 6 cores and 12 threads, while the AMD Ryzen Threadripper 3990X is a 7 nm Zen 2 (Castle Peak) part with 64 cores and 128 threads. The Intel chip is manufactured by Intel, whereas the AMD chip is fabricated by TSMC. The transistor count and die size reflect this scale difference: the Threadripper 3990X has 30,400 million transistors across 8x 74 mm² dies, while the Intel part has no listed transistor or die size data.

Cache configuration diverges sharply. The Intel Core i7-10750H has 12 MB of shared L3 cache, while the Threadripper 3990X has 256 MB of L3. Both have 64 KB of L1 per core, but the L2 cache differs: 256 KB per core on Intel versus 512 KB per core on AMD. This larger cache hierarchy on the AMD part directly supports its massive thread count, reducing memory access latency in heavily parallel workloads.

Memory bandwidth is another major differentiator. The Intel part supports dual-channel DDR4 with a bandwidth of 46.9 GB/s, while the AMD part supports quad-channel DDR4 with a bandwidth of 102.4 GB/s. This 55 GB/s advantage is critical for feeding 64 cores. The platform also differs: the Intel i7-10750H uses Intel BGA 1440 and is a mobile part, while the Threadripper 3990X uses AMD Socket TRX4 and is a desktop part.

PCIe connectivity and integrated graphics highlight their different target markets. The Intel part has PCIe Gen 3 with 16 lanes and includes UHD Graphics, while the AMD part has PCIe Gen 4 with 64 lanes and no integrated graphics. The AMD chip also supports an unlocked multiplier, enabling overclocking, whereas the Intel chip is locked. Neither processor supports ECC memory, according to the data.

The Verdict

The data is unambiguous: the AMD Ryzen Threadripper 3990X is the superior processor for any workload that scales with thread count. It wins 13 of 14 head-to-head benchmarks, and its multi-core scores are often over seven times higher than the Intel Core i7-10750H. The 64-core, 128-thread configuration delivers a level of parallel performance that the 6-core, 12-thread Intel part cannot approach. For rendering, scientific computing, or any task that uses all available cores, the Threadripper 3990X is the only viable choice from this data.

The Intel Core i7-10750H wins in exactly one scenario: the 3DMark single-thread test, where it scores 4.7% higher. This suggests the Intel part has a slight edge in lightly-threaded tasks that rely on a single core. However, even this advantage is inconsistent, as the AMD part wins every Cinebench single-core test and the Geekbench single-core test. The Intel part’s higher boost clock of 5.00 GHz does not translate into consistent single-thread superiority.

The market segments are clear from the specifications. The Intel Core i7-10750H is a mobile processor with a 45 W TDP and integrated graphics, designed for laptops. The AMD Ryzen Threadripper 3990X is a desktop processor with a 280 W TDP, no integrated graphics, and a launch MSRP of $3990, designed for high-end workstations. The Intel part is for users who need a capable processor in a power-constrained mobile chassis; the AMD part is for users who need maximum multi-threaded performance on a desktop.

Where Each One Wins

The AMD Ryzen Threadripper 3990X wins in every multi-threaded benchmark and most single-threaded benchmarks. Its 13 wins out of 14 comparisons make it the clear choice for rendering, video encoding, scientific simulations, and any workload that can utilize 64 cores and 128 threads. The Cinebench R23 multi-core score of 68,124 versus 9,718 shows it is roughly seven times faster in heavily parallel tasks. The 3DMark max-threads score of 18,441 versus 4,186 reinforces this, indicating the AMD part scales effectively with thread count.

The Intel Core i7-10750H wins only the 3DMark single-thread test, with a 4.7% edge. This suggests it holds a narrow advantage in a specific, lightly-threaded workload. The data does not support a broader single-thread victory for Intel, as the AMD part wins all Cinebench and Geekbench single-core tests. The Intel part’s 45 W TDP and integrated graphics make it suitable for mobile laptops, but its performance in this comparison is limited to that single 3DMark test.

For users prioritizing maximum multi-core throughput, the Threadripper 3990X is the definitive winner. For users who need a mobile processor with integrated graphics and a lower TDP, the Intel Core i7-10750H exists, but it sacrifices the massive parallel performance of the AMD part. The choice is not between two similar CPUs; it is between a mobile processor and a desktop workstation powerhouse.
