Intel Core i5-1340P vs Intel Core i9-10900F Comparison

The Intel Core i9-10900F and Intel Core i5-1340P occupy different corners of the processor market. The i9-10900F is a 10-core, 20-thread desktop part from Comet Lake, while the i5-1340P is a 12-core, 16-thread mobile part from Raptor Lake. In the database's head-to-head Cinebench tests, the i9-10900F wins all six comparisons, with margins between 6.6% and 6.7%. The i5-1340P counters with a 10 nm process, integrated Iris Xe graphics, and a 28 W TDP.

Where Each One Wins

The recorded head-to-head benchmarks show a clean sweep for the i9-10900F. It wins every Cinebench R15, R20, and R23 test, both single-core and multi-core. The i5-1340P does not win any of the six comparisons. However, the i5-1340P has advantages outside raw compute. It is the only one of the two with integrated graphics (Iris Xe Graphics 80EU). It also has a much lower TDP of 28 W versus 65 W, and it uses a mobile BGA 1744 socket, making it suitable for laptops and compact systems. The i9-10900F, by contrast, is a desktop part on Socket 1200 with a 65 W TDP and no integrated graphics. For workloads that rely on the CPU alone, the i9-10900F is the clear winner in the database. For systems that need a GPU output without a discrete card, or that must fit in a low-power mobile chassis, the i5-1340P is the only viable choice.

Architecture Differences

The two processors diverge on nearly every architectural axis. The i9-10900F uses Comet Lake on a 14 nm process, while the i5-1340P uses Raptor Lake on a 10 nm process. The i9-10900F has 10 cores and 20 threads; the i5-1340P has 12 cores and 16 threads. Despite having fewer cores, the i9-10900F offers more threads, which contributes to its multi-core performance. Cache layouts also differ: the i9-10900F has 64 KB of L1 per core and 256 KB of L2 per core, with 20 MB of shared L3. The i5-1340P has 80 KB of L1 per core and 2 MB of L2 per core, with 12 MB of shared L3. The i9-10900F's larger L3 pool is notable, while the i5-1340P's larger per-core L2 may help with certain access patterns.

Memory support separates the two as well. The i9-10900F supports only DDR4, while the i5-1340P supports both DDR4 and DDR5. The i9-10900F has a recorded memory bandwidth of 46.9 GB/s; the i5-1340P has no recorded memory bandwidth in the database. PCIe connectivity also differs: the i9-10900F provides PCIe Gen 3 with 16 lanes, while the i5-1340P provides PCIe Gen 4 with 20 lanes. The i5-1340P's newer PCIe standard and higher lane count are clear advantages for storage and expansion in a mobile context.

The i9-10900F has no integrated graphics, while the i5-1340P includes Iris Xe Graphics 80EU. This makes the i5-1340P self-contained for display output, whereas the i9-10900F requires a discrete GPU. The i9-10900F is a desktop part with a 65 W TDP; the i5-1340P is a mobile part with a 28 W TDP. The i9-10900F uses Socket 1200, the i5-1340P uses BGA 1744. The i9-10900F is end-of-life, while the i5-1340P is active. The i9-10900F was released on 2020-04-29, the i5-1340P on 2023-01-03. The i9-10900F had a launch MSRP of $464, the i5-1340P of $353.

Both processors have a locked multiplier and no ECC support. Their percentiles against all CPUs in the database are identical at 58. The i9-10900F's average benchmark score is 4664, while the i5-1340P's is 4545. In the nearest-rival context, the i9-10900F sits 0.3% above the Intel Core i9-9900KF and 0.4% below the Intel Core i9-11900T. The i5-1340P is level with the Intel Core i7-10700KF and 0.7% above the Intel Core i5-1250P.

Head-to-Head Benchmarks

The head-to-head results are consistent across all six Cinebench tests. In Cinebench R15 multicore, the i9-10900F scores 1688 against 1584, a 6.6% lead. In R15 single-core, it scores 238 versus 223, a 6.7% lead. In R20 multicore, the i9-10900F scores 7036 against 6600, a 6.6% lead. In R20 single-core, it scores 993 versus 931, a 6.7% lead. In R23 multicore, the i9-10900F scores 16753 against 15716, a 6.6% lead. In R23 single-core, it scores 2365 versus 2218, a 6.6% lead.

The uniformity of these margins is striking. The i9-10900F maintains a 6.6% to 6.7% advantage across every workload, regardless of thread count or rendering engine. This suggests a consistent per-clock performance edge, likely stemming from its higher boost clock of 5.20 versus 4.60 for the i5-1340P. The i9-10900F also has 20 threads versus 16, which helps in multi-core tests. The i5-1340P's 12 cores do not compensate for its lower thread count and lower boost clock in these benchmarks.

The average benchmark scores reinforce the head-to-head picture. The i9-10900F's average of 4664 is 2.6% higher than the i5-1340P's 4545. Both processors land at the 58th percentile of all CPUs, meaning they occupy the same performance tier overall, but the i9-10900F sits at the top of that tier.

The Verdict

The data is unambiguous: the i9-10900F outperforms the i5-1340P in every recorded Cinebench test. For desktop users who prioritize raw multi-threaded and single-threaded performance, the i9-10900F is the stronger choice. Its 20 threads and 20 MB of L3 cache contribute to a 6.6% lead in multi-core workloads. The i5-1340P, however, is the only option for mobile systems, with a 28 W TDP, integrated graphics, and a BGA 1744 socket. It also brings a newer 10 nm process and PCIe Gen 4 support. The i5-1340P is not a performance winner in this comparison, but it serves a different use case. The i9-10900F is end-of-life, while the i5-1340P is active, which may affect availability. Ultimately, the choice depends on whether the system needs desktop performance or mobile flexibility.
