Architecture Differences

The two processors come from different generations and design philosophies. The i9-10900E uses the Comet Lake architecture on a 14 nm process, built for desktop systems with an Intel Socket 1200. It has 10 cores and 20 threads, with a base clock of 2.80 GHz and a boost clock of 4.70 GHz. Its cache layout includes 64 KB of L1 per core, 256 KB of L2 per core, and a shared 20 MB L3 pool.

The i5-1340P uses the Raptor Lake architecture, specifically the Raptor Lake-P variant, built on a 10 nm process. It is a mobile part using Intel BGA 1744. It has 12 cores and 16 threads, with a base clock of 1900.00 MHz and a boost clock of 4.60 GHz. The cache differs considerably: 80 KB of L1 per core, 2 MB of L2 per core, and a shared 12 MB L3.

The process node difference is significant. The 14 nm Comet Lake design is older and larger, with a die size of 206 mm², while the database does not list a die size for the 10 nm Raptor Lake-P chip. The newer node typically allows higher efficiency, and the TDP figures reflect that: the i9-10900E has a 65 W TDP, while the i5-1340P runs at 28 W. That is a substantial power envelope difference, with the mobile chip drawing less than half the power of the desktop part.

Memory support also diverges. The i9-10900E supports DDR4 only, with dual-channel operation and a rated memory bandwidth of 46.9 GB/s. The i5-1340P supports both DDR4 and DDR5, also dual-channel, but the database does not record a bandwidth figure. PCIe connectivity differs as well: the i9 offers Gen 3 with 16 lanes from the CPU, while the i5 offers Gen 4 with 20 lanes.

Integrated graphics differ too. The i9-10900E carries UHD Graphics 630, while the i5-1340P uses Iris Xe Graphics 80EU. Neither chip supports ECC memory. Both are listed as active production parts, with the i9 releasing on 2020-04-29 and the i5 on 2023-01-03.

Where Each One Wins

The recorded data shows a clean sweep: the i9-10900E wins all six head-to-head benchmarks. However, the margins are small, and the context matters for real-world use.

The i9-10900E wins in both single-core and multi-core Cinebench tests. Its largest advantage is 2.5% in Cinebench R20 single-core, where it scores 954 versus 931. The smallest margin is 2.2% in Cinebench R15 single-core, with scores of 228 and 223. In multi-core tests, the i9 leads by 2.4% consistently across R15, R20, and R23. For workloads that stress sustained multi-threaded performance, such as rendering or compilation, the i9's 20 threads and higher boost clock give it a measurable edge.

The i5-1340P does not win any benchmark in the head-to-head comparison. Its strengths lie elsewhere: it is a mobile processor with a 28 W TDP, which the data shows as a much lower power envelope than the i9's 65 W. It also supports newer memory standards, DDR4 and DDR5, and has more PCIe Gen 4 lanes. For a laptop or compact mobile system, the i5's efficiency and platform features matter more than the small benchmark deficit.

In terms of overall standing, the i9-10900E sits at the 59th percentile among all CPUs, while the i5-1340P sits at the 58th. The average benchmark score for the i9 is 4708, and for the i5 it is 4545. The i9's nearest rivals include the Intel Core i9-11900T with an average score of 4685 and a 0.5% delta, and the Intel Core i9-10900F at 4664 with a 0.9% delta. The i5's nearest rivals include the Intel Core i7-10700KF at 4547 with a 0% delta and the Intel Core i5-1250P at 4515 with a 0.7% delta.

Head-to-Head Benchmarks

The head-to-head data covers three Cinebench versions, each with single-core and multi-core tests. The i9-10900E wins every one.

In Cinebench R15 multi-core, the i9 scores 1622 against 1584 for the i5, a 2.4% margin. In Cinebench R15 single-core, the i9 scores 228 against 223, a 2.2% margin. These are the smallest gaps in the comparison, but they still favor the i9.

Cinebench R20 shows a slightly larger spread. In multi-core, the i9 scores 6759 versus 6600, again a 2.4% difference. In single-core, the i9 scores 954 versus 931, which is the largest relative win at 2.5%. This indicates the i9's single-thread performance advantage is consistent across Cinebench versions.

Cinebench R23, the most current of the three, shows the i9 at 16093 in multi-core against 15716 for the i5, a 2.4% gap. In single-core, the i9 scores 2272 against 2218, also a 2.4% margin. The consistency of these deltas, all between 2.2% and 2.5%, suggests the performance difference is stable across workload types and benchmark generations.

Outside the head-to-head set, the i9 also has Geekbench results: 8162 multi-core and 1575 single-core. The i5 does not have Geekbench scores recorded in the database. For users relying on Geekbench as a reference point, only the i9 has data available.

The overall benchmark averages reinforce the picture. The i9-10900E averages 4708 across its recorded benchmarks, placing it at the 59th percentile. The i5-1340P averages 4545, placing it at the 58th percentile. The 3.6% difference in average score matches the pattern of the head-to-head results, where the i9 leads by roughly 2.4% in most tests.

The Verdict

The data points to a straightforward conclusion: the Intel Core i9-10900E is the faster processor in every benchmark recorded. It wins all six Cinebench head-to-head comparisons, holds a higher average benchmark score, and sits one percentile point higher in the overall CPU ranking. For anyone building a desktop system and prioritizing raw compute performance, the i9-10900E is the choice based on these measurements.

The margins, however, are not dramatic. The largest win is 2.5%, and most are 2.4%. That means the i5-1340P is not far behind in raw throughput. In multi-core workloads, the i5's 12 cores help it stay close despite having only 16 threads against the i9's 20. The i9's higher boost clock, 4.70 GHz versus 4.60 GHz, likely contributes to its consistent advantage in both single and multi-threaded tests.

The i5-1340P makes its case on platform and efficiency rather than benchmark wins. It is a mobile processor with a 28 W TDP, less than half the i9's 65 W envelope. It supports DDR5 memory, offers PCIe Gen 4 with 20 lanes, and uses a newer 10 nm process. It also carries a lower launch MSRP of $353 compared to $488 for the i9. For a laptop or a compact mobile workstation, the i5 is the sensible pick despite the small performance deficit.

The i9-10900E is a desktop part on Intel Socket 1200 with DDR4 memory support and PCIe Gen 3. Its 20 MB of shared L3 cache and 20 threads give it an edge in heavily threaded applications. Its launch MSRP of $488 reflects its position as a higher-tier desktop processor, though it is from an older generation.

Choose the i9-10900E if you need the fastest recorded performance and are building a desktop system. Choose the i5-1340P if you need a mobile platform, lower power draw, newer memory and PCIe standards, and accept a small trade-off in benchmark scores. The database shows no scenario where the i5 beats the i9 in compute tests, but its advantages in efficiency and platform features are clear from the specifications.
