Intel Core i7-1180G7 vs Intel Core i7-6700T Comparison

The Intel Core i7-1180G7 and Intel Core i7-6700T represent two distinct eras of Intel mobile and desktop design, yet benchmark results show a surprisingly consistent performance gap. The 1180G7, a Tiger Lake-U part, wins every single head-to-head benchmark in the data, despite the 6700T having a significantly higher base clock. The 1180G7’s advantage is uniform across all Cinebench tests, with the multicore and singlecore deltas hovering in a narrow band between 11.9% and 12.3%. This consistency suggests a fundamental architectural efficiency advantage rather than a workload-specific quirk. Both processors hold the same 43rd percentile ranking among all CPUs, indicating they are peers in the broader performance landscape, but the 1180G7 edges ahead in every measured scenario.

Head-to-Head Benchmarks

The data is unambiguous: the 1180G7 outperforms the 6700T in every single Cinebench test recorded. The largest delta appears in the multi-core tests, where the 1180G7 scores 6672 in Cinebench R23 multicore versus 5943 for the 6700T, a 12.3% lead. The R20 multicore test shows a similar story, with the 1180G7 at 2802 and the 6700T at 2496, also a 12.3% difference. In R15 multicore, the scores are 672 and 599, respectively, yielding a 12.2% advantage for the 1180G7.

Single-core performance tells the same tale. The 1180G7 posts 942 in Cinebench R23 singlecore, beating the 6700T’s 839 by 12.3%. In R20 singlecore, the margin is 395 versus 352, a 12.2% win. The R15 singlecore test shows 94 against 84, an 11.9% lead. The narrow spread of these deltas—from 11.9% to 12.3%—is remarkable. It indicates that the 1180G7’s advantage is not tied to thread scaling or burst clocks, but rather to a consistent per-clock efficiency edge. The 6700T, with its higher base clock of 2.80 GHz versus 1.30 GHz, cannot overcome the IPC gains of the newer architecture.

The average benchmark scores further contextualize these wins. The 1180G7 averages 1930 across all benchmarks, while the 6700T averages 1918. This is a slim 0.6% overall margin, yet the head-to-head Cinebench results show a much larger gap. The reason is that the 6700T’s average includes a Geekbench multicore score of 3906 and a singlecore score of 1128, which are not present in the 1180G7’s benchmark set. The 1180G7’s nearest rivals include the AMD Opteron 6348 at an identical 1930 average, the Intel Core i3-10300 at 1934 (-0.2%), and the Intel Xeon E3-1231 v3 at 1925 (0.3%). The 6700T’s nearest rivals are the AMD Ryzen 3 7320U at 1916 (0.1%), the Intel Core i3-10305T at 1922 (-0.2%), and the Intel Xeon E-2314 at 1911 (0.4%). This places both chips in the same performance tier, but the 1180G7 consistently finishes ahead in the tests they share.

Where Each One Wins

The 1180G7 wins everywhere in the head-to-head data, but the nature of its wins suggests specific use cases. For multi-threaded productivity workloads, such as video encoding or 3D rendering, the 1180G7’s 12.3% lead in Cinebench R23 multicore is the headline figure. A score of 6672 versus 5943 means the 1180G7 completes render tasks measurably faster, despite running at a much lower base clock. The 6700T, with its 35W TDP, is a capable desktop part, but it cannot match the efficiency of the 10nm Tiger Lake design.

For single-threaded tasks—like web browsing, office applications, or legacy software that relies on one core—the 1180G7 again holds a 12.3% advantage in R23 singlecore. The 942 score versus 839 is a meaningful gap for responsiveness. The 6700T’s higher base clock (2.80 GHz) does not help it close the gap because the 1180G7’s boost clock of 4.60 GHz is substantially higher, and the newer microarchitecture delivers more instructions per clock. The data shows no scenario where the 6700T takes a win, so users prioritizing any Cinebench-measured performance metric should favor the 1180G7.

However, the 6700T is not without context. Its Geekbench scores—3906 multicore and 1128 singlecore—are not directly comparable to the 1180G7 because the latter lacks Geekbench results in the FACT PACK. The 6700T also benefits from a desktop socket (Intel Socket 1151) and 16 PCIe Gen 3 lanes, which may be preferable for systems requiring discrete GPU expansion. The 1180G7, with only 4 PCIe Gen 4 lanes, is limited to mobile or compact designs. Thus, while the 1180G7 wins every benchmark, the 6700T wins on platform flexibility for desktop builders who need more I/O lanes.

Architecture Differences

The architectural chasm between these two chips is wide. The 1180G7 is built on Intel’s 10nm process node and uses the Willow Cove-U core architecture, part of the Tiger Lake family. The 6700T, in contrast, uses the 14nm node and the older Skylake architecture. This node difference is the primary driver of the performance-per-watt gap, with the 1180G7’s TDP rated at just 9 watts versus the 6700T’s 35 watts.

Cache configuration also differs substantially. The 1180G7 has 80 KB of L1 cache per core and a large 1.25 MB of L2 cache per core, with 12 MB of shared L3 cache. The 6700T has 64 KB of L1 per core, 256 KB of L2 per core, and only 8 MB of shared L3. The 1180G7’s larger L2 cache, in particular, reduces latency for frequently accessed data, contributing to its superior single-core performance. The die size also tells a story: the 1180G7 measures 144 mm², while the 6700T’s die size is not listed, but the smaller node allows more transistors in a comparable area.

The integrated graphics are another major divergence. The 1180G7 pairs its CPU cores with Iris Xe-LP Graphics G7 with 96 execution units, a significant step up from the 6700T’s HD Graphics 530. While no graphics benchmarks are provided, the architectural difference is clear: Tiger Lake’s GPU is designed for modern media and light gaming, while Skylake’s HD 530 is an older, less capable design. Both processors lack ECC memory support and have locked multipliers, but the 1180G7 supports LPDDR4X memory, whereas the 6700T supports DDR3 and DDR4.

Specification Differences

The specification sheet highlights how far Intel moved in five years. The 1180G7 has a base clock of 1.30 GHz and a boost clock of 4.60 GHz, while the 6700T runs at a 2.80 GHz base and 3.60 GHz boost. The 1180G7’s lower base clock is a trade-off for its 9W TDP, but its higher boost clock allows it to surge ahead when needed. The 6700T’s 35W TDP is more than triple, reflecting its desktop-oriented power budget.

The sockets are incompatible: the 1180G7 uses Intel BGA 1598 (soldered to the motherboard), while the 6700T uses Intel Socket 1151 (LGA, replaceable). The memory support differs, with the 1180G7 limited to LPDDR4X and the 6700T accepting both DDR3 and DDR4. Both have dual-channel memory buses and identical 34.1 GB/s memory bandwidth. PCIe support is a notable split: the 1180G7 offers Gen 4 with 4 lanes, while the 6700T offers Gen 3 with 16 lanes. This means the 6700T can connect more devices directly to the CPU, but the 1180G7’s Gen 4 lanes offer higher per-lane bandwidth.

The 1180G7’s launch MSRP was $426, while the 6700T launched at $303. The 1180G7 released on 2021-03-30, and the 6700T on 2015-08-31. Both are end-of-life products. The 1180G7’s part number is SRK0D, while the 6700T lists as SR2BUSR2L3. The 1180G7 is classified as a Mobile segment part, and the 6700T as Desktop. The 1180G7’s generation is listed as “Core i7 (Willow Cove-U)” and the 6700T’s as “Core i7 (Skylake).” Both processors have 4 cores and 8 threads, but the 1180G7’s smaller process node and newer architecture deliver the benchmark wins.
