Intel Core i5-1130G7 vs Intel Core i7-5775R Comparison

The Intel Core i7-5775R and Intel Core i5-1130G7 are both 4-core, 8-thread processors, but they belong to different eras and market segments. The i7-5775R is a desktop Broadwell part from 2015, while the i5-1130G7 is a mobile Tiger Lake chip from 2020. Despite the older chip’s higher TDP and desktop positioning, the newer mobile processor wins every single benchmark in this comparison, though the margins are consistently narrow. The data shows a clear, if modest, performance advantage for the i5-1130G7 across all tested workloads.

Head-to-Head Benchmarks

The i5-1130G7 sweeps all six benchmark comparisons, with every win falling in a tight band between 9.1% and 9.4%. In Cinebench R15 multi-core, the i5-1130G7 scores 706 against the i7-5775R’s 641, a 9.2% advantage. The single-core R15 result is nearly identical in percentage terms: 99 versus 90, a 9.1% lead. Moving to Cinebench R20, the multi-core test shows 2942 versus 2671, again a 9.2% difference, while single-core R20 scores 415 against 376, a slightly larger 9.4% gap.

The pattern holds in the newer Cinebench R23 tests. Multi-core R23 gives the i5-1130G7 a 7006 score compared to 6360 for the i7-5775R, a 9.2% margin. Single-core R23 shows 989 versus 897, a 9.3% lead for the mobile chip. The consistency of these deltas across different benchmark versions is notable; it suggests the performance gap is systematic rather than workload-specific. The i7-5775R’s best showing is in Geekbench, where it posts 3996 multi-core and 1218 single-core, but the i5-1130G7 has no Geekbench scores in the data pack, so no direct comparison is possible there.

Both processors land at the 45th percentile among all CPUs, indicating they are statistically equivalent in overall standing. The average benchmark score is similarly close: 2031 for the i7-5775R versus 2026 for the i5-1130G7. However, that average includes Geekbench results for the i7-5775R, which are absent for the i5-1130G7, so the average does not reflect the head-to-head sweep. In the direct comparisons available, the i5-1130G7 is consistently ahead by roughly 9-10%, which is a meaningful margin for synthetic rendering tests.

FAQ

A: In single-core R20, the i5-1130G7 scores 415, while the i7-5775R scores 376. The delta is 9.4%, making it the largest single-core margin in the head-to-head data.

Q: Do both processors have the same number of cores and threads?

A: Yes, both the Intel Core i7-5775R and the Intel Core i5-1130G7 have 4 cores and 8 threads. The performance difference comes from architectural and clock speed advantages, not core count.

Q: Which processor has a larger L3 cache?

A: The i5-1130G7 has 8 MB of shared L3 cache, while the i7-5775R has 6 MB of shared L3 cache. The i5-1130G7 also has larger per-core L1 and L2 caches.

Q: How do the average benchmark scores compare?

A: The i7-5775R has an average benchmark score of 2031, while the i5-1130G7 averages 2026. The i7-5775R is marginally ahead in this metric, but this includes Geekbench scores that are not available for the i5-1130G7.

Where Each One Wins

The i5-1130G7 wins every benchmark where both processors have scores. This includes all three generations of Cinebench (R15, R20, R23) in both single-core and multi-core tests. The margins are uniform, ranging from 9.1% to 9.4%, which suggests the i5-1130G7’s newer architecture provides a consistent generational uplift. For users running rendering or CPU-bound workloads, the i5-1130G7 is the clear choice based on the data.

The i7-5775R has no direct benchmark wins in this comparison. However, it does have Geekbench scores (3996 multi-core, 1218 single-core) that the i5-1130G7 lacks in the data pack, so its standing in that specific test cannot be assessed. The i7-5775R also benefits from a desktop socket (Intel BGA 1364) and a 65W TDP, which indicates it is designed for sustained operation in a desktop chassis, whereas the i5-1130G7 is a 15W mobile part. If the workload involves Geekbench-style tests, the i7-5775R at least has measurable scores, but the head-to-head data gives the i5-1130G7 the edge everywhere it counts.

In terms of raw performance per benchmark, the i5-1130G7 is the winner. The i7-5775R’s only claim to a win is the absence of Geekbench data for its rival, which is not a true victory. For practical purposes, the i5-1130G7 is the faster processor in every workload represented in the head-to-head table.

Specification Differences

The two processors differ significantly in clock speeds, TDP, and platform support. The i7-5775R has a base clock of 3.30 GHz and a boost clock of 3.80 GHz, while the i5-1130G7 has a base clock of 1100.00 MHz (1.10 GHz) and a boost clock of 4.00 GHz. The i7-5775R runs at a 65W TDP, whereas the i5-1130G7 is rated at just 15W, making the mobile chip far more power-efficient on paper.

Memory support also differs. The i7-5775R uses DDR3 with a dual-channel bus and a memory bandwidth of 29.9 GB/s. The i5-1130G7 uses DDR4 with a dual-channel bus and a much higher memory bandwidth of 68.3 GB/s. PCIe support is one generation apart: the i7-5775R has Gen 3 with 16 lanes (CPU only), while the i5-1130G7 has Gen 4 with 16 lanes (CPU only).

The i7-5775R has a launch MSRP of $384, while the i5-1130G7 has no launch MSRP listed. The i7-5775R is end-of-life and was released on 2015-05-14, whereas the i5-1130G7 is active and was released on 2020-09-01. The i7-5775R uses the Intel BGA 1364 socket, and the i5-1130G7 uses the Intel BGA 1598 socket, so they are not interchangeable.

Integrated graphics differ as well: the i7-5775R has Iris Pro Graphics 6200, while the i5-1130G7 has Iris Xe Graphics G7 80EU. Neither processor has an unlocked multiplier, and both lack ECC memory support. The i7-5775R has a die size of 182 mm², while the i5-1130G7’s die size is not listed.

Architecture Differences

The i7-5775R is built on Intel’s Broadwell architecture using a 14 nm process node, while the i5-1130G7 uses the Tiger Lake architecture (specifically Willow Cove-U) on a 10 nm process node. Both are manufactured by Intel, but the newer 10 nm node gives the i5-1130G7 a transistor density advantage that partially explains its higher performance despite a much lower TDP.

Cache hierarchies differ substantially. The i7-5775R has 64 KB of L1 cache per core and 256 KB of L2 cache per core, with 6 MB of shared L3 cache. The i5-1130G7 has 96 KB of L1 cache per core and 1.25 MB of L2 cache per core, with 8 MB of shared L3 cache. The i5-1130G7’s L2 cache is nearly five times larger per core, which likely contributes to its single-core performance lead.

The market segment and production status also reflect architectural positioning. The i7-5775R is a desktop part that is end-of-life, while the i5-1130G7 is an active mobile processor. The i5-1130G7’s 15W TDP is a hallmark of Tiger Lake-U’s focus on efficiency, whereas the i7-5775R’s 65W TDP is typical of a desktop Broadwell chip. The i5-1130G7’s higher memory bandwidth (68.3 GB/s versus 29.9 GB/s) aligns with its newer DDR4 support and Gen 4 PCIe, which the i7-5775R lacks.

The Verdict

The data is unambiguous: the Intel Core i5-1130G7 is the faster processor in every head-to-head benchmark. It leads by 9.1% to 9.4% across all Cinebench tests, making it the better choice for rendering and CPU-intensive tasks. The i5-1130G7 achieves this with a 15W TDP versus the i7-5775R’s 65W, which is a remarkable efficiency gain from the newer 10 nm Tiger Lake architecture.

The i7-5775R, however, is not without a niche. It has measurable Geekbench scores (3996 multi-core, 1218 single-core) that the i5-1130G7 lacks in this data, and its desktop socket (Intel BGA 1364) and 65W TDP suggest it is built for sustained, high-power operation in a fixed chassis. If a user specifically needs a desktop Broadwell part with Iris Pro Graphics 6200, the i7-5775R is the only option, but it is end-of-life and costs $384 at launch.

For anyone comparing these two directly, the i5-1130G7 is the superior performer in all tested workloads. It is also an active product with Gen 4 PCIe and DDR4 support, making it more future-proof. The i7-5775R’s only advantages are its lower average benchmark score (2031 versus 2026, a negligible 0.2% difference) and its availability of Geekbench data, which is not a functional benefit. Choose the i5-1130G7 for raw speed and efficiency; choose the i7-5775R only if the desktop platform or specific integrated graphics are required.
