Intel Atom x7809C vs Intel Core i7-10750H Comparison

The Intel Core i7-10750H and Intel Atom x7809C occupy very different positions in the mobile processor landscape, despite their average benchmark scores being surprisingly close. The Core i7 is a high-performance part from the 10th Gen Comet Lake-H family, while the Atom x7809C is a power-sipping Amston Lake design. The data shows a clear split: the Core i7 dominates almost every compute-heavy test, but the Atom has a few unexpected strengths that make it relevant for specific workloads.

Head-to-Head Benchmarks

The most striking result is the sheer number of wins for the Core i7-10750H. Out of 17 head-to-head comparisons, the Core i7 takes 16 victories. The margin is not uniform, though. In Cinebench tests, the Core i7's lead is consistent and significant. Across Cinebench R15, R20, and R23, both multi-core and single-core scores, the Core i7 wins by roughly 21.5% to 22.1%. For example, in Cinebench R23 multi-core, the Core i7 scores 9718 versus the Atom's 7997, a 21.5% advantage. Single-core R23 shows a similar story: 1372 versus 1129, also a 21.5% gap.

The differences become even more pronounced in certain PassMark workloads. The Core i7's lead in extended instructions is enormous, scoring 10470 against the Atom's 5509, a 90.1% difference. This indicates a massive advantage in workloads that leverage modern instruction sets like AVX. Single-thread performance is another area of clear superiority, with the Core i7 scoring 2625 versus the Atom's 1462, a 79.5% lead. Data compression also favors the Core i7 heavily, with a score of 167213 versus 111525, a 49.9% difference.

Floating-point math and integer math also show the Core i7 ahead by 40.4% and 37.3%, respectively. Random string sorting is another win for the Core i7, at 36.2%. Prime number finding is a 34.5% win, and PassMark multithread shows a 23.5% lead for the Core i7. Even the closest contest, PassMark physics, goes to the Core i7, but by a razor-thin margin of just 2%.

The Atom x7809C's single win is in PassMark data encryption. Here, the Atom scores 7832, which is a full 49.8% higher than the Core i7's score of 3930. This is an outlier result that suggests the Atom's Gracemont cores have a significant advantage in certain cryptographic workloads, likely due to hardware acceleration. This is the only test where the Atom is competitive, and it is a decisive victory in that specific area.

FAQ

Q: Is the Intel Core i7-10750H always faster than the Atom x7809C?

Q: How big is the performance gap in multi-core rendering?

A: The Core i7-10750H is consistently about 21.5% faster in Cinebench multi-core tests. In R23 multi-core, it scores 9718 versus the Atom's 7997.

Q: Which processor is better for single-threaded tasks?

A: The Core i7-10750H is substantially better. Its PassMark single-thread score is 2625, which is 79.5% higher than the Atom's 1462. Cinebench R20 single-core shows a similar 21.5% advantage.

Q: Does the Atom x7809C have any advantage besides encryption?

A: The recorded data shows only one benchmark win for the Atom. In every other measured test, it trails the Core i7, with margins ranging from 2% in physics to 90.1% in extended instructions.

Q: What is the overall average performance difference?

A: The average benchmark scores are very close. The Core i7-10750H has an average score of 13024, while the Atom x7809C has an average of 12607. This places the Core i7 only about 3% higher overall, despite its dominance in individual tests.

Q: How does the Core i7 compare to its own rivals?

A: The Core i7-10750H's average score of 13024 puts it in the 68th percentile of all CPUs. Its nearest rivals include the Intel Core i5-9400F, which is 0.1% slower, and the Intel Core Ultra 3 105UL, which is 0.3% slower. It is 1.8% faster than the Intel Core i3-1210U.

The Verdict

The data presents a clear choice. The Intel Core i7-10750H is the superior processor for virtually all general-purpose computing tasks. Its wins in Cinebench, PassMark integer math, floating-point math, and single-thread tests make it the obvious pick for productivity, content creation, and any workload that benefits from raw CPU power. The 21.5% lead in multi-core rendering and the 79.5% lead in single-thread performance are decisive.

The Intel Atom x7809C is not a general-purpose alternative. Its single benchmark win in data encryption suggests it could be a specialized choice for network appliances or security-focused devices where cryptographic throughput is the primary concern. Its 49.8% advantage in that one test is significant. However, outside of that niche, the Atom is consistently slower, often by large margins. Its average score of 12607 is only slightly below the Core i7's 13024, but that average is pulled up by the encryption result. For any other application, the Core i7 is the correct choice.

Specification Differences

The two processors differ in nearly every fundamental specification. The Core i7-10750H has 6 cores and 12 threads, while the Atom x7809C has 8 cores and 8 threads. The Core i7 has a base clock of 2.60 GHz and a boost clock of 5.00 GHz, compared to the Atom's 2.00 GHz base and 3.60 GHz boost. The thermal design power is also very different: the Core i7 is rated at 45 watts, while the Atom is rated at just 25 watts.

The Core i7 uses the Intel BGA 1440 socket, while the Atom uses the Intel BGA 1264 socket. Memory support differs as well. The Core i7 supports only DDR4 with a dual-channel memory bus and a peak bandwidth of 46.9 GB/s. The Atom supports both DDR4 and DDR5, but only on a single-channel bus with a lower peak bandwidth of 38.4 GB/s. The Core i7 offers 16 PCIe Gen 3 lanes from the CPU, while the Atom offers only 9. The Core i7 also includes integrated UHD Graphics, while the Atom has no integrated graphics. The Core i7 was released in April 2020, while the Atom was released in April 2024.

Architecture Differences

The architectural gap is generational. The Core i7-10750H is built on Intel's 14 nm process using the Comet Lake-H architecture, specifically the Comet Lake microarchitecture. The Atom x7809C is built on a 10 nm process using the Amston Lake architecture, which employs Gracemont efficiency cores. This is a fundamental difference in design philosophy.

Cache configurations also differ significantly. The Core i7 has 64 KB of L1 cache and 256 KB of L2 cache per core, with 12 MB of shared L3 cache. The Atom has 96 KB of L1 cache per core and 2 MB of L2 cache per module, with only 6 MB of shared L3 cache. The Atom's smaller shared L3 cache is notable, especially given its 8 cores.

Feature support further separates them. The Core i7 supports a wider memory bus and higher bandwidth, as well as more PCIe lanes and integrated graphics. The Atom's single-channel memory and lack of integrated graphics reflect its more limited role. The Atom's single win in encryption suggests it has specialized cryptographic instructions or hardware, but the database does not detail specific instruction set extensions beyond the benchmark results.

Where Each One Wins

The Intel Core i7-10750H is the winner for any task that relies on general CPU performance. This includes video editing, 3D rendering, software compilation, and everyday multitasking. Its 21.5% lead in Cinebench R23 multi-core and its 79.5% lead in PassMark single-thread make it suitable for both heavily threaded and lightly threaded applications. Its 90.1% lead in extended instructions means it is particularly strong in scientific computing and other AVX-heavy workloads. For a laptop user who needs one machine to do everything, the Core i7 is the clear choice.

The Intel Atom x7809C has exactly one area of dominance: data encryption. Its 49.8% lead in PassMark data encryption makes it the better option for a dedicated security appliance, a VPN gateway, or any device that spends most of its time encrypting and decrypting data streams. Its lower 25-watt TDP also suggests it fits in thermally constrained designs, though the database does not provide cooling requirements. However, for any other task, including basic productivity or media playback, the Core i7 will deliver better performance. The Atom's 8 cores and 8 threads cannot overcome the Core i7's higher clocks and superior single-thread execution.
