Intel Core i7-1375PRE vs Intel Core i9-9820X Comparison

The Intel Core i9-9820X and Intel Core i7-1375PRE represent two very different approaches to CPU design: a high-power desktop part from 2018 versus a low-power mobile processor from 2023. The benchmark data reveals a surprisingly tight contest, with the older i9-9820X winning all six head-to-head Cinebench comparisons, albeit by a narrow margin. The largest advantage for the i9-9820X comes in the Cinebench R20 single-core test, where it scores 1034 against the i7-1375PRE's 1021, a delta of 1.3%. The multi-core tests tell a similar story, with the i9-9820X posting a 7332 in R20 multicore versus 7239 for its rival, also a 1.3% gap. Across the entire benchmark suite, the i9-9820X consistently edges out the i7-1375PRE, with every single test result landing within a 1.2% to 1.3% margin of victory.

Head-to-Head Benchmarks

The data from the six Cinebench tests paints a clear picture of a processor that is consistently ahead, but never by a wide margin. In the Cinebench R15 multicore test, the i9-9820X scores 1759, while the i7-1375PRE scores 1737, giving the older chip a 1.3% lead. The single-core R15 test shows a similar pattern: 248 for the i9-9820X versus 245 for the i7-1375PRE, a 1.2% difference. This consistency is notable, as it suggests the performance gap is not workload-dependent but rather a reflection of a fundamental, albeit small, advantage.

Moving to the more demanding Cinebench R20 suite, the i9-9820X again takes the lead in both tests. Its multicore score of 7332 surpasses the i7-1375PRE's 7239 by 1.3%. In single-core R20, the i9-9820X scores 1034, which is also 1.3% higher than the 1021 achieved by the i7-1375PRE. These results reinforce the idea that the i9-9820X holds a slight but consistent edge in raw processing power, regardless of the render load.

The final and most recent test, Cinebench R23, follows the exact same pattern. The i9-9820X achieves a multicore score of 17459, while the i7-1375PRE manages 17236, a 1.3% delta. In single-core R23, the scores are 2464 and 2433 respectively, again a 1.3% advantage for the i9-9820X. The fact that the deltaPct remains at 1.3% across multiple generations of the Cinebench benchmark indicates that the performance relationship between these two CPUs is stable and predictable. The i9-9820X is the winner in all six comparisons, but its victories are narrow, with no single test showing a lead greater than 1.3%.

Where Each One Wins

Based strictly on the benchmark results, the Intel Core i9-9820X wins in every tested category. There are no Cinebench tests where the i7-1375PRE comes out ahead. The i9-9820X’s wins span both single-core and multi-core workloads, meaning it holds the advantage in lightly-threaded tasks like everyday application responsiveness and in heavily-threaded tasks like 3D rendering. The data shows a clean sweep, with the i9-9820X taking all six head-to-head benchmark victories.

For the i7-1375PRE, there are no wins to analyze in the provided benchmark suite. However, its strengths lie outside of raw Cinebench performance. The data shows it has a significantly lower TDP of 28 watts compared to 165 watts for the i9-9820X. This indicates that the i7-1375PRE is designed for power-constrained environments, such as laptops, where efficiency is more critical than peak performance. Its active production status and mobile market segment further suggest it is intended for systems where the i9-9820X's desktop socket and power requirements would be impractical. The i7-1375PRE also features integrated Iris Xe Graphics, which the i9-9820X lacks entirely, making it a more complete package for systems without a discrete GPU.

Architecture Differences

The two processors are built on fundamentally different architectures and process nodes. The i9-9820X uses the Skylake architecture on a 14 nm process node, with the codename Skylake-X. It is part of the Core i9 X-Series 9th Gen family. In contrast, the i7-1375PRE is based on the Raptor Lake architecture on a 10 nm node, with the codename Raptor Lake-P, belonging to the Core i7 Raptor Lake-P generation. This generational gap is significant, as the newer 10 nm process is designed to be more power-efficient than the older 14 nm process.

The core configurations also differ substantially. The i9-9820X has 10 cores and 20 threads, while the i7-1375PRE has 14 cores and 20 threads. This means the i7-1375PRE has four more physical cores, but it uses a hybrid architecture (implied by Raptor Lake-P) to manage power. Cache hierarchies differ as well: the i9-9820X has 64 KB of L1 cache and 1 MB of L2 cache per core, with a shared 16.5 MB L3 cache. The i7-1375PRE has 80 KB of L1 and 2 MB of L2 per core, with a larger 24 MB shared L3 cache. Despite having more cores and more cache, the i7-1375PRE still trails in all benchmarks, suggesting the i9-9820X's higher base and boost clocks of 3.30 GHz and 4.20 GHz respectively, combined with its desktop-optimized design, are more impactful for Cinebench performance.

Memory support is another differentiator. The i9-9820X supports DDR4 memory over a quad-channel bus, providing a memory bandwidth of 85.3 GB/s. The i7-1375PRE supports both DDR4 and DDR5, but over a dual-channel bus, and its memory bandwidth is not listed. The i9-9820X also offers more PCIe lanes: 44 lanes of Gen 3, compared to 20 lanes of Gen 4 on the i7-1375PRE. The i9-9820X has an unlocked multiplier, while the i7-1375PRE is locked, and its TDP of 165 watts is nearly six times higher than the 28-watt TDP of the mobile part.

The Verdict

The benchmark data is unambiguous: the Intel Core i9-9820X is the faster processor in every Cinebench test included in this comparison. It wins all six head-to-head matchups, with a maximum lead of 1.3%. For users whose priority is raw multi-threaded rendering performance, as measured by Cinebench, the i9-9820X is the correct choice. Its higher average benchmark score of 5049, compared to 4985 for the i7-1375PRE, and its higher percentile ranking (60th vs 59th) support this conclusion.

However, the data also shows that the i7-1375PRE is not a performance slouch. Despite its much lower TDP of 28 watts, it comes within 1.3% of the i9-9820X, which consumes 165 watts. This makes the i7-1375PRE an exceptionally efficient performer for its power class. The choice between these two depends entirely on the use case. If the application requires maximum performance and power consumption is not a concern, the i9-9820X is the winner. If the system must be mobile, battery-powered, or operate within a strict thermal envelope, the i7-1375PRE is the only viable option, offering near-identical performance at a fraction of the power. The i9-9820X is the performance winner, but the i7-1375PRE is a more modern, integrated, and power-efficient design.
