CPU Comparison

The Intel Atom x7835RE and Intel Core i7-1165G7 are both mobile processors from Intel, but they target vastly different use cases. The Atom is a low-power, efficiency-focused part built on the Amston Lake architecture, while the Core i7 is a higher-performance Tiger Lake-U chip. Benchmark data reveals a clear performance hierarchy, with the Core i7 winning 16 of 17 head-to-head tests, yet the Atom holds its own in specific efficiency-oriented workloads. The data shows both processors occupy the same overall performance percentile, making the choice between them dependent on workload-specific requirements rather than raw capability alone.

Architecture Differences

The architectural divide between these two processors is fundamental. The Intel Atom x7835RE is built on the Amston Lake architecture with Gracemont efficiency cores, fabricated on Intel's 10 nm process. It features 8 cores and 8 threads, a configuration focused on parallel throughput for low-power scenarios. In contrast, the Intel Core i7-1165G7 uses the Tiger Lake architecture with Willow Cove-U cores, also on a 10 nm process, but with only 4 cores and 8 threads, relying on higher clock speeds and Hyper-Threading for performance.

Cache hierarchies differ substantially. The Atom x7835RE has 96 KB of L1 cache per core and 2 MB of L2 cache per module, with a shared 6 MB L3 cache. The Core i7-1165G7 has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and a larger 12 MB shared L3 cache. This larger L3 cache on the Core i7 is a significant factor in its superior performance in cache-sensitive workloads.

Memory support also diverges. The Atom x7835RE supports DDR4 and DDR5 memory with a single-channel memory bus and a memory bandwidth of 38.4 GB/s. The Core i7-1165G7 supports DDR4 and LPDDR4X with a dual-channel memory bus. The dual-channel configuration on the Core i7 provides a bandwidth advantage, though no specific bandwidth figure is listed for it.

Integrated graphics differ as well. The Atom x7835RE is equipped with UHD Graphics 32EU, while the Core i7-1165G7 features Iris Xe-LP Graphics G7 96EU. The Core i7's integrated GPU has three times the execution units, indicating a significantly more capable graphics solution. PCIe support also differs: the Atom uses Gen 3 with 9 lanes, while the Core i7 uses Gen 4 with 4 lanes, offering newer but fewer lanes.

The Verdict

The data strongly favors the Intel Core i7-1165G7 for general-purpose performance. It wins 16 of the 17 head-to-head benchmarks, with victories ranging from 18.1% in Passmark floating point math to 50.6% in Passmark extended instructions. Its single-thread advantage of 42.1% in Passmark tests makes it the clear choice for responsive, lightly-threaded applications.

The Intel Atom x7835RE should be selected for scenarios prioritizing power efficiency over performance. With a TDP of 12 watts versus the Core i7's 28 watts, the Atom is suited for fanless or thermally constrained designs. Its sole benchmark victory in data encryption (5579 vs 5561) is negligible, but its lower power draw and support for DDR5 memory make it viable for specific embedded or always-on workloads.

Both processors sit at the 65th percentile of all CPUs, and their average benchmark scores are close (9430 vs 9235). However, the Core i7-1165G7 is the superior performer in nearly every measurable workload. The Atom x7835RE's appeal lies entirely in its efficiency profile, not its benchmark results. For users who need raw compute, the Core i7 is the choice; for those who need a low-power x86 processor, the Atom is the only sensible option.

Specification Differences

The two processors differ across nearly every core specification. The Intel Atom x7835RE has 8 cores and 8 threads, while the Intel Core i7-1165G7 has 4 cores and 8 threads. Base clock speeds are 1.30 GHz for the Atom and 2.80 GHz for the Core i7. Boost clocks are 3.60 GHz and 4.70 GHz, respectively.

Thermal design power is a major differentiator: the Atom x7835RE is rated at 12 watts TDP, while the Core i7-1165G7 is rated at 28 watts. The Atom uses an Intel BGA 1264 socket, while the Core i7 uses an Intel BGA 1449 socket. The Atom's architecture is Amston Lake with a Gracemont core generation, whereas the Core i7 uses Tiger Lake with a Willow Cove-U core generation.

Cache configurations differ. The Atom has 96 KB of L1 cache per core and 2 MB of L2 cache per module, with a 6 MB shared L3 cache. The Core i7 has 80 KB of L1 cache per core and 1.25 MB of L2 cache per core, with a 12 MB shared L3 cache. The die size also differs, with the Core i7 measuring 144 mm² while the Atom has no listed die size.

Memory support varies: the Atom supports DDR4 and DDR5 with a single-channel bus and 38.4 GB/s bandwidth, while the Core i7 supports DDR4 and LPDDR4X with a dual-channel bus and no listed bandwidth. PCIe capabilities are Gen 3 with 9 lanes on the Atom versus Gen 4 with 4 lanes on the Core i7. Integrated graphics are UHD Graphics 32EU on the Atom and Iris Xe-LP Graphics G7 96EU on the Core i7.

Production status and release dates also differ. The Atom x7835RE is listed as Active with a release date of April 2024, while the Core i7-1165G7 is End-of-life with a release date of September 2020. The launch MSRP for the Atom is $127, while the Core i7 launched at $426.

Head-to-Head Benchmarks

The Core i7-1165G7 dominates the benchmark comparison across all major test categories. In Cinebench R23 multicore, it scores 8293 versus the Atom's 6051, a 27% advantage. The single-core Cinebench R23 results are similarly lopsided: 1170 for the Core i7 against 854 for the Atom, also a 27% gap. This pattern holds across Cinebench R15 and R20, with the Core i7 leading by 27% in both multicore and single-core tests.

Passmark results show the Core i7's largest win in extended instructions, where it scores 7323 against the Atom's 3617, a 50.6% margin. Prime number finding also favors the Core i7 by exactly 50%, with scores of 46 versus 23. Single-thread Passmark results show a 42.1% lead for the Core i7 (2763 vs 1599), while multithread Passmark scores are 9958 versus 7119, a 28.5% difference.

The Atom x7835RE's only victory comes in Passmark data encryption, where it scores 5579 against the Core i7's 5561, a 0.3% margin. This is a narrow win and represents the only benchmark where the Atom outperforms its rival. Other Passmark tests show the Core i7 leading by margins between 18.1% and 20.2%, including floating point math (19830 vs 16236), integer math (33349 vs 26623), and random string sorting (12698 vs 10180). Data compression also favors the Core i7 with a 25.9% lead (103497 vs 76736).

The overall benchmark count is decisive: the Core i7-1165G7 wins 16 head-to-head comparisons, while the Atom x7835RE wins just 1. Despite this, both processors land at the same 65th percentile of all CPUs, and their average scores are within 2% of each other. The Core i7's consistent, substantial wins in standard workloads make it the higher-performing processor, while the Atom's single encryption victory is too isolated to alter the overall performance picture.
