Intel Core i5-1130G7 vs Intel Core i7-3960X Comparison

# Where Each One Wins

The Intel Core i7-3960X wins every single head-to-head benchmark in this comparison. The data is unambiguous: across all six Cinebench tests, the Sandy Bridge-E desktop flagship outperforms the Tiger Lake-U mobile chip. The i7-3960X takes the multicore crown with scores of 722 (Cinebench R15), 3011 (R20), and 7170 (R23), while the i5-1130G7 trails at 706, 2942, and 7006 respectively. Single-core results follow the same pattern: the i7-3960X posts 102, 425, and 1012 across R15, R20, and R23, against the i5-1130G7's 99, 415, and 989.

The wins are narrow but consistent. Every deltaPct sits between 2.3% and 3.0%, meaning the i7-3960X holds a small but repeatable edge in both single-threaded and multi-threaded workloads. There is no workload category—not rendering, not single-core responsiveness, not multi-core throughput—where the i5-1130G7 manages to pull ahead. The i7-3960X also has a Geekbench presence, scoring 3193 multicore and 657 singlecore, while the i5-1130G7 has no Geekbench scores listed in the data.

This is a case where the older, larger, and more power-hungry desktop part simply outruns the newer, efficiency-oriented mobile part. The i5-1130G7's advantages—a 10 nm process node, higher boost clock, and integrated graphics—do not translate into benchmark victories. The i7-3960X's six cores and twelve threads, combined with a 15 MB shared L3 cache, deliver enough throughput to edge out the four-core, eight-thread i5-1130G7 in every measured scenario.

Head-to-Head Benchmarks

The largest margin comes in Cinebench R15 single-core, where the i7-3960X posts 102 against the i5-1130G7's 99—a 3.0% advantage. This is the only test where the deltaPct exceeds 2.5%. The i7-3960X's boost clock is 3.90 GHz, which is lower than the i5-1130G7's 4.00 GHz, yet the older chip still manages to win. This suggests that architectural efficiency differences and cache hierarchy play a larger role than raw clock speed in this specific comparison.

The Cinebench R20 single-core test shows a 2.4% gap (425 vs 415), while R23 single-core shows 2.3% (1012 vs 989). The multicore tests are uniformly at 2.3% deltas: R15 at 722 vs 706, R20 at 3011 vs 2942, and R23 at 7170 vs 7006. Across all six tests, the i7-3960X's minimum lead is 2.3% and maximum is 3.0%. The consistency of these margins—never exceeding 3%, never dropping below 2.3%—indicates that the i7-3960X has a stable, workload-independent performance advantage over the i5-1130G7.

The i5-1130G7 has no benchmark wins in the head-to-head data. Its average benchmark score is 2026, compared to the i7-3960X's 2037. Both chips sit at the 45th percentile among all CPUs, placing them in the same performance tier despite the i7-3960X's victories. The nearest rivals corroborate this: the i7-3960X's closest competitor is the AMD Opteron 6386 SE (avg score 2038, 0% delta), while the i5-1130G7's nearest rival is the Intel Core i5-1145GRE (avg score 2025, 0.1% delta). These are adjacent chips in the broader CPU landscape, even though the i7-3960X wins every direct comparison.

Specification Differences

The two processors differ in nearly every physical and electrical specification. The i7-3960X has 6 cores and 12 threads, while the i5-1130G7 has 4 cores and 8 threads. Base clocks are dramatically different: the i7-3960X runs at 3.30 GHz base, while the i5-1130G7 has a 1100.00 MHz base clock—a design choice for mobile power efficiency. Boost clocks are closer, with the i7-3960X at 3.90 GHz and the i5-1130G7 at 4.00 GHz. Thermal design power tells the real story: the i7-3960X consumes 130 W, while the i5-1130G7 is rated at 15 W. That is an 8.7x difference in power envelope.

Socket compatibility is entirely different: the i7-3960X uses Intel Socket 2011, while the i5-1130G7 is soldered to Intel BGA 1598. The i7-3960X supports quad-channel DDR3 memory with 51.2 GB/s bandwidth; the i5-1130G7 uses dual-channel DDR4 with 68.3 GB/s bandwidth. PCIe connectivity differs as well: the i7-3960X offers Gen 3 with 40 lanes (CPU only), while the i5-1130G7 provides Gen 4 with 16 lanes (CPU only). The i7-3960X has an unlocked multiplier; the i5-1130G7 is locked. The i7-3960X's launch MSRP was $990, while no launch MSRP is listed for the i5-1130G7.

Architecture Differences

The i7-3960X is built on Sandy Bridge-E architecture, a 32 nm process with 2,270 million transistors on a 435 mm² die. This is a desktop-class, end-of-life product released on 2011-11-13. The i5-1130G7 uses Tiger Lake architecture (specifically Willow Cove-U), fabricated on a 10 nm process. The transistor count and die size for the i5-1130G7 are not listed in the data. The i5-1130G7 is an active mobile product released on 2020-09-01.

Cache layouts differ substantially. The i7-3960X has 64 KB L1 per core, 256 KB L2 per core, and 15 MB shared L3. The i5-1130G7 has 96 KB L1 per core, 1.25 MB L2 per core, and 8 MB shared L3. The i7-3960X's larger L3 cache (15 MB vs 8 MB) is likely a factor in its benchmark wins, particularly in multi-threaded workloads where shared cache access matters. The i5-1130G7 compensates with larger per-core L1 and L2 caches, but the data shows this does not overcome the i7-3960X's aggregate resources.

The i7-3960X belongs to the Core i7 Extreme (Sandy Bridge-E) generation, while the i5-1130G7 is part of the Core i5 (Willow Cove-U) generation. The market segments reflect this: the i7-3960X is a desktop part, the i5-1130G7 is mobile. Neither chip supports ECC memory. The i5-1130G7 includes integrated graphics (Iris Xe Graphics G7 80EU), which the i7-3960X lacks entirely.

The Verdict

The data points to a clear conclusion: the Intel Core i7-3960X is the faster processor in every benchmark category measured. It wins all six Cinebench head-to-head tests with margins ranging from 2.3% to 3.0%. Buyers who prioritize raw compute performance—whether in single-core or multi-core tasks—should choose the i7-3960X based on the benchmark evidence alone.

The i5-1130G7 is not without merit, but its strengths lie outside the benchmark suite. It has integrated graphics, a 10 nm process node, higher memory bandwidth (68.3 GB/s vs 51.2 GB/s), and a dramatically lower 15 W TDP compared to the i7-3960X's 130 W. For a mobile or low-power system, the i5-1130G7 is the only viable choice, as the i7-3960X requires a desktop Socket 2011 platform and quad-channel DDR3 memory. The i5-1130G7's 4.00 GHz boost clock exceeds the i7-3960X's 3.90 GHz, but this does not translate into benchmark wins.

The i7-3960X's unlocked multiplier is an additional asset for enthusiasts, though the data does not include overclocked results. Its 40 PCIe Gen 3 lanes also provide more expansion capability than the i5-1130G7's 16 Gen 4 lanes. The i7-3960X's 15 MB L3 cache doubles the i5-1130G7's 8 MB, which correlates with its multicore performance advantage.

For users building a desktop workstation or high-end gaming rig where power consumption is not a constraint, the i7-3960X is the superior choice according to this benchmark data. For users needing a compact, low-power mobile solution with integrated graphics, the i5-1130G7 is the only option that fits the form factor—but they should expect slightly lower performance across the board. The verdict is data-driven and consistent: the i7-3960X wins on performance, while the i5-1130G7 wins on efficiency and mobility.
