Intel Core i5-1350P vs Intel Core i9-10900E Comparison

The Intel Core i5-1350P and Intel Core i9-10900E occupy the same performance percentile, both sitting at the 59th percentile against all CPUs, but they achieve this from opposite design philosophies. The i5-1350P is a mobile Raptor Lake processor with 12 cores and 16 threads, while the i9-10900E is a desktop Comet Lake chip with 10 cores and 20 threads. Across the six shared Cinebench benchmarks, the i5-1350P wins every single test, but the margins are uniformly thin at 2.6% in each case. The average benchmark score tells a similar story: the i5-1350P scores 4776, while the i9-10900E scores 4708. This is a close contest where the newer mobile part edges out the older desktop part in raw compute, but the differences are small enough that other factors like platform, memory support, and integrated graphics become decisive for a buyer.

The Verdict

The data points to a clear but narrow victory for the Intel Core i5-1350P in pure computational performance. It wins all six head-to-head Cinebench comparisons, including a 2.6% lead in both single-core and multi-core tests across R15, R20, and R23. For example, in Cinebench R23 multi-core, the i5-1350P scores 16514 versus the i9-10900E’s 16093, and in single-core it scores 2331 versus 2272. The i9-10900E does have a Geekbench multi-core score of 8162 and a single-core score of 1575, but no corresponding i5-1350P data exists for that test, so it cannot be used to claim a win.

The i5-1350P is the better choice for anyone prioritizing CPU benchmark performance in a mobile or space-constrained system, given its 28 W TDP and BGA 1744 socket. The i9-10900E is the better choice for desktop builders who need a Socket 1200 part with 20 threads, a 65 W TDP, and a larger 20 MB shared L3 cache. The i9-10900E also supports DDR4 memory with a measured memory bandwidth of 46.9 GB/s, whereas the i5-1350P supports both DDR4 and DDR5 but lacks a published bandwidth number. If the workload is heavily multi-threaded and the platform is fixed as desktop, the i9-10900E remains viable, but the benchmark data shows the i5-1350P is consistently ahead in Cinebench.

Where Each One Wins

The Intel Core i5-1350P wins every benchmark recorded in the head-to-head table. This includes Cinebench R15 multi-core (1664 vs 1622), R15 single-core (234 vs 228), R20 multi-core (6935 vs 6759), R20 single-core (979 vs 954), R23 multi-core (16514 vs 16093), and R23 single-core (2331 vs 2272). The delta is a consistent 2.6% across all six tests, indicating a uniform performance advantage rather than a workload-specific one. This means the i5-1350P is the winner in both lightly-threaded and heavily-threaded Cinebench workloads, which are representative of rendering and general CPU compute.

The Intel Core i9-10900E does not win any of the six head-to-head benchmarks, but it has strengths that the i5-1350P lacks. It offers 20 threads versus 16, which is a 25% thread-count advantage, and its 20 MB shared L3 cache is larger than the i5-1350P’s 12 MB. It also has a higher base clock of 2.80 GHz compared to 1.90 GHz, though both boost to 4.70 GHz. For workloads that scale with thread count beyond the Cinebench tests, the i9-10900E’s extra threads could be beneficial, but the data available does not show a scenario where it wins. The i9-10900E also has a Geekbench multi-core score of 8162, but without a comparable i5-1350P score, it is not possible to declare a winner in that test.

Architecture Differences

The two processors come from different Intel generations and are built on different process nodes. The Intel Core i5-1350P uses Raptor Lake architecture (codename Raptor Lake-P) on a 10 nm process, while the Intel Core i9-10900E uses Comet Lake architecture (codename Comet Lake) on a 14 nm process. This process difference is significant: the 10 nm node allows the i5-1350P to achieve higher performance within a 28 W TDP, whereas the i9-10900E requires a 65 W TDP to reach similar performance levels.

Core and cache configurations differ notably. The i5-1350P has 12 cores and 16 threads, with an L1 cache of 80 KB per core and an L2 cache of 2 MB per core. The i9-10900E has 10 cores and 20 threads, with an L1 cache of 64 KB per core and an L2 cache of 256 KB per core. The shared L3 cache is larger on the i9-10900E at 20 MB, compared to 12 MB on the i5-1350P. The i9-10900E also has a larger die size of 206 mm², while the i5-1350P’s die size is not listed.

Memory and PCIe support diverge as well. The i5-1350P supports both DDR4 and DDR5 memory with dual-channel bus, while the i9-10900E supports only DDR4 with dual-channel bus and a published memory bandwidth of 46.9 GB/s. The i5-1350P has PCIe Gen 4 with 20 lanes (CPU only), while the i9-10900E has PCIe Gen 3 with 16 lanes (CPU only). Integrated graphics also differ: the i5-1350P uses Iris Xe Graphics 80EU, while the i9-10900E uses UHD Graphics 630. Both processors have locked multipliers and do not support ECC memory.

Head-to-Head Benchmarks

The head-to-head results are remarkably consistent, with the Intel Core i5-1350P winning every test by exactly 2.6%. In Cinebench R15 multi-core, the i5-1350P scores 1664 versus 1622 for the i9-10900E. The single-core R15 test shows 234 versus 228. Moving to Cinebench R20, the multi-core scores are 6935 for the i5-1350P and 6759 for the i9-10900E, while single-core is 979 versus 954. In Cinebench R23, the multi-core gap is 16514 to 16093, and single-core is 2331 to 2272.

These consistent 2.6% deltas suggest a fundamental per-clock or per-architecture advantage for the i5-1350P, despite the i9-10900E’s higher base clock (2.80 GHz vs 1.90 GHz) and equal boost clock (4.70 GHz). The i5-1350P achieves its wins with 4 fewer threads and a smaller L3 cache, pointing to the efficiency of the Raptor Lake architecture on the 10 nm node. The i9-10900E’s Geekbench scores (8162 multi-core, 1575 single-core) are listed but cannot be compared directly because the i5-1350P has no Geekbench results in the data. In the six comparable tests, the i5-1350P has 6 wins and the i9-10900E has 0 wins.
