Intel Core i5-1035G7 vs Intel Core i7-6700T Comparison

The Intel Core i5-1035G7 and the Intel Core i7-6700T are both 4-core, 8-thread processors, but they represent very different design philosophies and eras. The i5-1035G7 is a modern, power-sipping mobile chip built on the 10 nm Ice Lake architecture, while the i7-6700T is a desktop processor from the older 14 nm Skylake generation. The benchmark data shows a clear overall winner, but the distinctions in platform, efficiency, and market positioning tell a more nuanced story.

Where Each One Wins

The data is unambiguous in terms of raw performance: the Intel Core i5-1035G7 wins every single benchmark recorded in the database. Across six head-to-head Cinebench tests, the i5-1035G7 takes all six wins, while the i7-6700T has zero. The victory margins are remarkably consistent, ranging from 13.1% to 13.4% in favor of the i5-1035G7. This is not a case of one chip being better at certain workloads; the i5-1035G7 simply outperforms the i7-6700T across the board in multi-core and single-core rendering tasks.

However, the i7-6700T is not without its own advantages in context. It is a desktop part with a higher base clock of 2.80 GHz compared to the i5-1035G7's 1.20 GHz, and it supports both DDR3 and DDR4 memory, whereas the i5-1035G7 only supports DDR4. The i7-6700T also has a larger 8 MB shared L3 cache versus the i5-1035G7's 6 MB. For users on an existing Socket 1151 platform, the i7-6700T may be a drop-in upgrade path, but from a pure performance standpoint, the i5-1035G7 leads in every measured category.

Architecture Differences

The two processors come from different architectural generations. The Intel Core i5-1035G7 is built on Ice Lake, specifically the Sunny Cove-U microarchitecture, fabricated on Intel's 10 nm process node. Its die size is recorded at 123 mm². In contrast, the Intel Core i7-6700T uses the older Skylake architecture on a 14 nm process node, with no die size recorded in the database. This process shrink is a major factor in the i5-1035G7's efficiency and performance uplift.

Cache hierarchies also differ. The i5-1035G7 has 80 KB of L1 cache per core, while the i7-6700T has 64 KB per core. Both share the same 256 KB L2 per core, but the i7-6700T compensates with a larger 8 MB shared L3 cache, compared to the i5-1035G7's 6 MB. The integrated graphics differ as well: the i5-1035G7 features Iris Plus graphics, while the i7-6700T is equipped with HD Graphics 530. The i5-1035G7 also has a significantly higher memory bandwidth rating at 51.2 GB/s, more than double the i7-6700T's 34.1 GB/s, despite both using dual-channel memory buses.

Thermal design is another key divider. The i5-1035G7 has a TDP of 15 watts, making it a low-power mobile part, while the i7-6700T draws 35 watts, a typical desktop low-power variant. The i5-1035G7 uses the Intel BGA 1526 socket, which is soldered to the motherboard, while the i7-6700T uses the LGA Socket 1151, which is replaceable. Production status also differs: the i5-1035G7 is listed as active, while the i7-6700T is end-of-life.

Head-to-Head Benchmarks

The head-to-head data is remarkably one-sided. The Intel Core i5-1035G7 wins all six recorded comparisons, with margins that hover tightly around 13%. The largest single win is in Cinebench R20 single-core, where the i5-1035G7 scores 399 against the i7-6700T's 352, a 13.4% lead. The smallest margin is in Cinebench R15 single-core, where the i5-1035G7's 95 beats the i7-6700T's 84 by 13.1%.

In multi-core tests, the i5-1035G7's advantage is consistent. In Cinebench R15 multi-core, it scores 678 versus 599, a 13.2% lead. In Cinebench R20 multi-core, the score is 2829 versus 2496, a 13.3% lead. The same 13.3% margin appears in Cinebench R23 multi-core, with 6736 versus 5943. This consistency suggests that the i5-1035G7's architectural efficiency, not just clock speed, is driving the performance gap.

The i7-6700T does have a higher base clock (2.80 GHz vs 1.20 GHz), but its boost clock is slightly lower (3.60 GHz vs 3.70 GHz). This, combined with the older Skylake IPC, means the i5-1035G7 is able to overcome the base clock deficit and pull ahead in sustained workloads. The i7-6700T's only recorded benchmark outside Cinebench is Geekbench, where it scores 3906 multi-core and 1128 single-core, but no comparable Geekbench score exists for the i5-1035G7 in the database, so a direct comparison is not possible.

The Verdict

Based strictly on the recorded data, the Intel Core i5-1035G7 is the superior processor. It wins every benchmark in the comparison set, with a consistent 13% advantage across all Cinebench tests. Its 10 nm Ice Lake architecture, higher boost clock, lower TDP, and faster memory bandwidth all contribute to this outcome. The i5-1035G7 also has a higher average benchmark score (1948 vs 1918) and a slightly better percentile ranking (44th vs 43rd).

The i7-6700T, however, is not without merit for its intended use case. It is a desktop part with a higher base clock, support for DDR3 memory, and a larger L3 cache. It also carries a launch MSRP of $303, which was recorded for its original release. For users on a Socket 1151 platform who cannot upgrade to a newer motherboard, the i7-6700T remains a viable option, but it is slower in every measured metric.

The verdict is clear: for raw performance, the i5-1035G7 is the better choice. The i7-6700T's only advantages are platform compatibility, memory flexibility, and its recorded launch price, none of which appear in the benchmark results. The database shows a younger, more efficient chip decisively outperforming an older desktop part.
