Intel Core i5-1340P vs Intel Core i7-9800X Comparison

The Intel Core i5-1340P and Intel Core i7-9800X occupy opposite ends of the Intel spectrum: one is a modern, power-efficient mobile processor, the other a legacy, high-power desktop part. Despite the generational gap and differing design philosophies, benchmark results show a surprisingly consistent outcome. The i5-1340P, a 12-core Raptor Lake-P part, outperforms the 8-core Skylake-X i7-9800X in every single head-to-head benchmark recorded. The data is unambiguous: across six Cinebench tests, the i5-1340P secures six wins, with the i7-9800X failing to claim a single victory.

Head-to-Head Benchmarks

The most striking aspect of this comparison is the uniformity of the results. The Intel Core i5-1340P wins every benchmark, but the margins are consistently narrow. In the Cinebench R15 multicore test, the i5-1340P scores 1584 against the i7-9800X’s 1553, a 2% lead. The single-core R15 result follows the same pattern, with the i5-1340P scoring 223 versus 219, a 1.8% advantage. These are not landslide victories, but they are decisive, especially considering the i7-9800X’s higher 3.80 GHz base clock and 4.50 GHz boost clock, which are closer to the i5-1340P’s 1.90 GHz base and 4.60 GHz boost than the core counts might suggest.

Moving to Cinebench R20, the trend holds. The i5-1340P scores 6600 in the multicore test, while the i7-9800X trails at 6474, a 1.9% delta. In single-core R20, the i5-1340P again leads with 931 points versus 913, a 2% difference. The most modern benchmark in the set, Cinebench R23, reinforces the narrative. The i5-1340P’s multicore score of 15716 is 1.9% higher than the i7-9800X’s 15416. In the R23 single-core test, the i5-1340P scores 2218, edging out the i7-9800X’s 2176 by 1.9%. The consistency of these deltas—hovering around 2%—suggests a fundamental architectural efficiency advantage for the newer Raptor Lake design rather than a raw throughput difference.

It is importantly the i7-9800X has additional benchmark data in Geekbench, scoring 7488 multicore and 1398 singlecore. However, since the head-to-head comparison data only includes Cinebench tests, the verdict on this matchup rests entirely on those six results. The i5-1340P’s average benchmark score of 4545 places it just ahead of the i7-9800X’s 4455, a gap of roughly 2%. Both processors sit at the 58th percentile of all CPUs, indicating they are firmly in the mid-range tier of performance, though the i5-1340P achieves this with a fraction of the power budget.

The Verdict

From the data, the Intel Core i5-1340P is the superior processor in this matchup. It wins all six head-to-head benchmarks, even if by narrow margins. For a mobile processor with a 28 W TDP to beat a desktop part with a 165 W TDP is a significant statement about architectural progression. The i5-1340P’s 12 cores and 16 threads, combined with its 10 nm process node, deliver higher scores than the i7-9800X’s 8 cores and 16 threads on a 14 nm node. The i5-1340P also offers integrated Iris Xe Graphics, while the i7-9800X has none, making the newer part a more complete package for systems without a discrete GPU.

However, the i7-9800X is not without its own merits. It features a quad-channel memory bus with a specified 85.3 GB/s bandwidth, which the i5-1340P’s dual-channel memory bus cannot match. It also supports 44 PCIe Gen 3 lanes, compared to the i5-1340P’s 20 Gen 4 lanes. For workloads that demand high I/O throughput or massive memory bandwidth, the i7-9800X’s platform could be more suitable, even if its raw compute scores are lower. The i7-9800X also has an unlocked multiplier, allowing for overclocking, whereas the i5-1340P is locked. The verdict is clear: for general compute and single-threaded performance, the i5-1340P is the better choice. The i7-9800X only makes sense for specific, bandwidth-intensive tasks.

Architecture Differences

The two processors are separated by five years of Intel architecture evolution. The Intel Core i5-1340P is built on Raptor Lake, with the codename Raptor Lake-P, and utilizes a 10 nm process node. In contrast, the Intel Core i7-9800X is based on the older Skylake architecture, specifically Skylake-X, manufactured on a 14 nm node. This process shrink is a primary driver of the i5-1340P’s efficiency and performance gains. The i5-1340P packs 12 cores and 16 threads, while the i7-9800X offers 8 cores and 16 threads. This means the i5-1340P uses a hybrid core arrangement to reach its thread count, whereas the i7-9800X relies on fewer, physically larger cores.

Cache configurations also differ notably. The i5-1340P has an 80 KB L1 cache per core and a 2 MB L2 cache per core, with a shared 12 MB L3 cache. The i7-9800X has a smaller 64 KB L1 and 1 MB L2 per core, but a larger shared 16.5 MB L3 cache. This larger L3 on the i7-9800X is a hallmark of the Skylake-X design, intended to serve its high-core-count desktop workload. Memory support diverges as well: the i5-1340P supports both DDR4 and DDR5 over a dual-channel bus, while the i7-9800X is limited to DDR4 over a quad-channel bus. The i7-9800X’s 85.3 GB/s memory bandwidth is a clear advantage, but the i5-1340P’s flexibility with newer memory standards is a modern benefit.

The platform differences are stark. The i5-1340P uses the Intel BGA 1744 socket and is classified as a mobile part, with a 28 W TDP. The i7-9800X uses the Intel Socket 2066 and is a desktop part with a 165 W TDP. The i5-1340P’s PCIe Gen 4 support with 20 lanes is newer, but the i7-9800X offers more physical lanes (44) albeit on PCIe Gen 3. The i5-1340P includes integrated Iris Xe Graphics with 80 execution units, while the i7-9800X has no integrated graphics at all. The i7-9800X is marked as end-of-life, while the i5-1340P is still active in production, indicating the former is a legacy product.

Where Each One Wins

The Intel Core i5-1340P is the winner in every Cinebench test, which measures both multicore and single-core rendering performance. This makes it the clear choice for general productivity, software compilation, and any workload that benefits from modern single-thread efficiency. Its 2% lead in multicore tests, despite having fewer physical cores than its rival’s larger design, suggests that its hybrid architecture and newer process node translate to better real-world throughput. For a mobile platform, the i5-1340P’s 28 W TDP and integrated graphics mean it can be deployed in thin-and-light laptops without a discrete GPU, making it a versatile option.

The Intel Core i7-9800X, despite losing all benchmarks, has specific areas where its platform excels. Its quad-channel memory bus with 85.3 GB/s bandwidth is a significant advantage for memory-intensive tasks like large-scale data analysis or high-resolution video editing, where memory speed is more critical than raw CPU compute. Its 44 PCIe Gen 3 lanes also provide more expansion options for multiple GPUs or high-speed storage devices, which is a common requirement in workstation builds. The unlocked multiplier allows for overclocking, potentially closing the performance gap, though the data provided does not include overclocked results. For a desktop user with a need for extreme I/O or memory bandwidth, the i7-9800X’s platform capabilities are its only saving grace. Otherwise, the i5-1340P is the superior processor across the board.
