AMD Ryzen Threadripper 3960X vs Intel Core i5-1035G1 Comparison

The Intel Core i5-1035G1 and AMD Ryzen Threadripper 3960X occupy opposite ends of the computing spectrum: one is a 15-watt mobile chip with integrated graphics, the other a 280-watt desktop flagship with 24 cores. The benchmark data is unambiguous about their relative performance, with the Threadripper winning all six head-to-head tests by a consistent 87% margin. The Intel chip, however, holds its own in its intended ultraportable segment, as evidenced by its 65th percentile ranking among all CPUs. This analysis walks through the raw scores, the competitive context, and the architectural reasoning behind the results.

Head-to-Head Benchmarks

The head-to-head results are one-sided in every category. In Cinebench R23 multi-core, the Threadripper scores 46557 against the i5-1035G1's 6062, a delta of -87% for the Intel part. The single-core R23 test tells a similar story: 6572 versus 855, again an 87% deficit. This pattern repeats across the entire Cinebench suite — R15 multi-core (4692 vs 611), R15 single-core (662 vs 86), R20 multi-core (19553 vs 2546), and R20 single-core (2760 vs 359) all show the same -87% gap. The consistency of that margin across every render test points to a fundamental throughput advantage rather than a workload-specific quirk.

The magnitude of the difference becomes clearer when contextualized. The Threadripper's R20 multi-core score of 19553 is more than seven times the i5-1035G1's 2546. In R23, the ratio is even steeper: 46557 divided by 6062 equals roughly 7.7x. The i5-1035G1's single-core scores are also far behind — its R20 single-core of 359 is a fraction of the Threadripper's 2760. Even in the most favorable test for the Intel part, the margin never narrows below the 87% threshold. The data shows no scenario where the i5-1035G1 closes the gap.

The broader benchmark picture reinforces this. The Threadripper posts an average benchmark score of 9284, while the i5-1035G1 averages 9684. That is unexpected: the Intel chip actually has a higher average score despite losing every head-to-head test. The reason lies in their respective nearest rivals. The i5-1035G1 sits within 2.2% of the Intel Core 3 N350 (9903, -2.2% delta) and the Intel Core i7-3770 (9706, -0.2% delta). The Threadripper's nearest rivals include the Intel Xeon Platinum 8280M (9260, +0.3% delta) and the Intel Core i5-10300H (9243, +0.4% delta). Both parts share a 65th percentile ranking, meaning they sit at the same position relative to all CPUs, but the Threadripper's peer group is composed of high-core-count server and desktop parts, while the i5-1035G1 competes with older mainstream chips.

The Verdict

The verdict is dictated by the data: the AMD Ryzen Threadripper 3960X is the superior processor for any workload that benefits from raw compute throughput. Its six consecutive head-to-head wins, each by an 87% margin, leave no room for ambiguity. The Threadripper's 24 cores and 48 threads give it a structural advantage that the i5-1035G1's 4 cores and 8 threads cannot overcome, regardless of clock speed or architecture efficiency.

However, the i5-1035G1 is not a failure; it is a different tool. Its 65th percentile ranking and average benchmark score of 9684 — which is actually higher than the Threadripper's 9284 — show that it performs well relative to its own market segment. The Intel part's nearest rival, the Intel Core i7-3770, has an average score of 9706, just 0.2% higher. That places the i5-1035G1 in the company of capable desktop processors from a previous generation, which is remarkable for a 15-watt mobile chip.

Who should pick which? The data says: choose the Threadripper if your workload scales with core count and you need maximum multi-threaded performance. Choose the i5-1035G1 if you require a low-power mobile processor with integrated graphics and your tasks are light enough to fit within its 4-core envelope. The Threadripper's launch MSRP is $1399, which reflects its position at the top of the desktop heap. The i5-1035G1 has no launch MSRP listed, but its mobile market segment and 15-watt TDP indicate a fundamentally different use case.

Where Each One Wins

The Threadripper wins every measurable benchmark in the head-to-head set, so the division of labor is clear. For multi-threaded render workloads — Cinebench R15, R20, and R23 multi-core — the Threadripper's 24 cores provide a decisive edge. The R23 multi-core score of 46557 is roughly 7.7 times the i5-1035G1's 6062, making it the obvious choice for 3D rendering, video encoding, and simulation tasks that can use all available threads.

The Threadripper also wins single-core tests, though the margin is proportionally similar. Its R20 single-core score of 2760 versus the i5-1035G1's 359 represents an 87% advantage, which is notable because single-core performance is often considered a weak point for high-core-count chips. Here, the Threadripper's 4.50 GHz boost clock and Zen 2 architecture deliver single-threaded performance that beats the i5-1035G1's 3.60 GHz boost by a wide margin.

The i5-1035G1's wins are not in the head-to-head data, but in its own benchmark suite. Its PassMark scores include a multi-thread score of 7211, a single-thread score of 2198, and a floating-point math score of 15483. These numbers are competitive for a mobile chip — the single-thread score of 2198 is within striking distance of the Threadripper's Geekbench single-core score of 1681, though the tests are not directly comparable. The i5-1035G1 also has integrated UHD Graphics, which the Threadripper lacks entirely, making it the only option of the two for systems without a discrete GPU.

Architecture Differences

The architectural divide between these two chips is stark. The i5-1035G1 uses Intel's Ice Lake architecture on a 10 nm process node, fabricated by Intel with a die size of 123 mm². The Threadripper uses AMD's Zen 2 architecture on a 7 nm process node, fabricated by TSMC with a die size of 4x 74 mm². The Threadripper's transistor count is listed at 15,200 million, while the i5-1035G1 has no transistor count listed. The process node difference — 10 nm versus 7 nm — partially explains why the Threadripper can pack 24 cores into a similar power envelope per core, though its total TDP is far higher.

The cache hierarchies are fundamentally different in scale. The i5-1035G1 has 80 KB of L1 cache per core, 256 KB of L2 per core, and 6 MB of shared L3 cache. The Threadripper has 64 KB of L1 per core, 512 KB of L2 per core, and a massive 128 MB of L3 cache. That 128 MB L3 cache is more than 20 times the i5-1035G1's 6 MB, providing a significant advantage for workloads that repeatedly access large datasets.

The memory subsystems also diverge. Both support DDR4 memory, but the i5-1035G1 uses a dual-channel bus with 51.2 GB/s bandwidth, while the Threadripper uses a quad-channel bus with 102.4 GB/s bandwidth — exactly double. Neither supports ECC memory. The PCIe capabilities differ as well: the i5-1035G1 supports PCIe Gen 3, while the Threadripper supports PCIe Gen 4, which doubles the potential bandwidth for compatible devices.

Specification Differences

The most obvious specification difference is core count: the i5-1035G1 has 4 cores and 8 threads, while the Threadripper has 24 cores and 48 threads. That 6x core advantage and 6x thread advantage directly drives the benchmark results. The base clocks also differ dramatically: the i5-1035G1 runs at 1000.00 MHz base and 3.60 GHz boost, while the Threadripper runs at 3.80 GHz base and 4.50 GHz boost. Even at base clock, the Threadripper is 2.8 GHz higher, and its boost clock is 0.9 GHz higher.

The TDP difference is equally stark: 15 watts for the i5-1035G1 versus 280 watts for the Threadripper. This is an 18.7x difference in power draw, which explains why the i5-1035G1 is classified as a mobile part and the Threadripper as a desktop part. The sockets are incompatible: Intel BGA 1526 for the i5-1035G1 versus AMD Socket TRX4 for the Threadripper. The i5-1035G1's multiplier is locked, while the Threadripper's is unlocked, allowing overclocking.

The market segments are also distinct: the i5-1035G1 is mobile, the Threadripper is desktop. The release dates are close, with the i5-1035G1 launching on 2019-07-31 and the Threadripper on 2019-11-24. The Threadripper has a launch MSRP of $1399; the i5-1035G1 has no launch MSRP listed. The part numbers differ, and the Threadripper's series is listed as "3000 series" while the i5-1035G1 has no series listed. Finally, the i5-1035G1 has integrated UHD Graphics, while the Threadripper has no integrated graphics.
