AMD Ryzen Threadripper 3960X vs Intel Core i7-1165G7 Comparison

The AMD Ryzen Threadripper 3960X and the Intel Core i7-1165G7 occupy opposite poles of the processor spectrum, yet their aggregate benchmark scores land them within 0.5% of each other. The data reveals a stark divergence: the Threadripper 3960X, a 24-core desktop behemoth, wins 13 of 14 head-to-head comparisons, while the i7-1165G7, a 4-core mobile chip, claims only a single victory. The average benchmark scores tell the story of a statistical tie — 9284 for AMD versus 9235 for Intel — but the underlying workloads could not be more different. This comparison is less about which chip is "better" and more about which type of processing demand each was engineered to satisfy.

Head-to-Head Benchmarks

The Threadripper 3960X dominates multi-threaded tests with margins that escalate dramatically as thread counts rise. In the 3DMark suite, the AMD part scores 9989 at 16 threads versus Intel's 2617, a 281.7% advantage. At 8 threads, the lead is 110.7% (5267 versus 2500), and at 4 threads it narrows to 37.7% (2775 versus 2015). The 2-thread test is the closest multi-core contest, with AMD ahead by just 7% (1436 versus 1342). The max-thread test shows the full gulf: 13978 versus 2645, a 428.5% blowout. Cinebench results amplify this pattern — R15 multicore shows 4692 versus 835 (461.9%), R20 multicore shows 19553 versus 3483 (461.4%), and R23 multicore shows 46557 versus 8293 (461.4%). Geekbench multicore adds another data point, with AMD winning 13326 versus 4467, a 198.3% margin.

The single-thread results are more nuanced. Intel wins the 3DMark single-thread test, scoring 811 versus 725, a 10.6% advantage. However, the Cinebench single-core tests flip decisively to AMD: R15 single-core shows 662 versus 117 (465.8%), R20 single-core shows 2760 versus 491 (462.1%), and R23 single-core shows 6572 versus 1170 (461.7%). Geekbench single-core is a closer affair, with AMD ahead 1681 versus 1578, a 6.5% margin. The Intel chip's lone head-to-head win in 3DMark single-thread suggests its Willow Cove cores have a specific strength in that synthetic test, but the broader Cinebench single-core data indicates the Zen 2 architecture handles that workload far more effectively. The 3DMark result appears to be an outlier rather than a trend.

The Verdict

The data points to a clear division of labor. Pick the AMD Ryzen Threadripper 3960X if your workloads scale with core count — the 24-core, 48-thread configuration produces benchmark leads of 428.5% in max-thread tests and 461.4% in Cinebench R23 multicore. The 65th percentile ranking against all CPUs (shared by both chips) masks the fact that the Threadripper's average score of 9284 is propped up almost entirely by multi-threaded wins. Its nearest rival, the Intel Xeon Platinum 8280M, sits just 0.3% behind at 9260, indicating that the Threadripper competes in server-class territory.

Pick the Intel Core i7-1165G7 for scenarios where the 3DMark single-thread score of 811 (a 10.6% advantage) matters, or where the integrated Iris Xe-LP Graphics G7 96EU eliminates the need for a discrete GPU. The i7-1165G7's end-of-life status and 28W TDP versus the Threadripper's 280W TDP also signal different deployment contexts. The Intel part's nearest rival, the Xeon Gold 5320, is within 0% deltaPct, suggesting it competes with server chips on aggregate metrics despite being a mobile processor. The Threadripper's 13 wins versus Intel's 1 win is decisive, but the single Intel victory — plus its integrated graphics — defines its niche.

Architecture Differences

The fundamental architectural split is node technology and core topology. The Threadripper 3960X uses TSMC's 7 nm process with 15,200 million transistors across a 4x 74 mm² die configuration, while the i7-1165G7 uses Intel's 10 nm process on a single 144 mm² die. The AMD chip employs Zen 2 architecture under the "Castle Peak" codename, offering 24 cores and 48 threads with a base clock of 3.80 GHz and boost clock of 4.50 GHz. The Intel part uses Willow Cove architecture under "Tiger Lake-U," with 4 cores and 8 threads, a 2.80 GHz base clock, and a higher 4.70 GHz boost clock.

Cache hierarchies diverge substantially. The Threadripper provides 64 KB L1 and 512 KB L2 per core, with a massive 128 MB L3 cache. The i7-1165G7 offers 80 KB L1 and 1.25 MB L2 per core, but only 12 MB of shared L3. Memory support differs too: AMD uses quad-channel DDR4 with 102.4 GB/s bandwidth, while Intel uses dual-channel DDR4 or LPDDR4X with no listed bandwidth. Both support PCIe Gen 4, though Intel limits it to 4 CPU lanes. The Threadripper requires an AMD Socket TRX4 motherboard, while the i7-1165G7 is soldered to Intel BGA 1449. The AMD part is unlocked for overclocking; the Intel part is locked. Neither supports ECC memory.

Where Each One Wins

The Threadripper 3960X wins every multi-threaded benchmark category by substantial margins. It excels in 3DMark max-thread (13978 versus 2645), Cinebench R23 multicore (46557 versus 8293), and Geekbench multicore (13326 versus 4467). It also wins single-core Cinebench tests by over 460% — a surprising result given Intel's higher boost clock. The data suggests the Threadripper's 24-core design, combined with its 128 MB L3 cache, provides superior throughput for rendering, compilation, and scientific computing workloads.

The i7-1165G7 wins only the 3DMark single-thread test (811 versus 725), indicating a specific strength in that synthetic workload. Its integrated Iris Xe-LP Graphics G7 96EU is a unique feature absent from the Threadripper, enabling GPU-accelerated tasks without a discrete card. The Intel chip also has a lower TDP (28W versus 280W), making it suitable for power-constrained mobile designs. Its 4.70 GHz boost clock is the highest of the two, and its 1.25 MB L2 per core is larger than AMD's 512 KB, which may benefit certain latency-sensitive applications.
