Intel Core i7-1370P vs Intel Core i9-9900K Comparison

The Intel Core i9-9900K and the Intel Core i7-1370P represent two very different approaches to x86 processing, separated by four years of architectural evolution and targeting entirely different market segments. The 9900K is an end-of-life desktop flagship from the Coffee Lake refresh era, while the 1370P is an active mobile processor built on Raptor Lake. The benchmark data shows a clear performance hierarchy, with the mobile i7-1370P winning 14 of the 17 head-to-head comparisons, but the desktop i9-9900K securing decisive victories in specific workloads that reveal its enduring strengths. The average benchmark scores are nearly identical—27097 for the 9900K and 26900 for the 1370P, a delta of just 0.7%—yet the distribution of wins tells a story of specialization rather than equivalence.

Where Each One Wins

The Intel Core i9-9900K dominates in three specific, narrowly-defined workloads. Its most significant victory comes in PassMark random string sorting, where it scores 36238 against the 1370P's 23580, a massive 53.7% advantage. This suggests the 9900K's memory subsystem and cache hierarchy are particularly well-suited to pointer-chasing and sorting algorithms. Similarly, in PassMark extended instructions, the 9900K posts 18965 versus 12822, a 47.9% lead, indicating superior execution of advanced instruction set extensions. The third win is in PassMark data compression, with the 9900K scoring 283506 against 217676, a 30.2% margin. These three wins are all in data-manipulation and compression-style tasks, pointing to a desktop processor optimized for raw throughput in memory-intensive, sequential workloads.

The Intel Core i7-1370P, by contrast, wins everywhere else. Its largest victory is in PassMark data encryption, where it scores 13067 against 6430, a 50.8% advantage. This is followed by PassMark find prime numbers, with the 1370P scoring 97 versus 47, a 51.5% lead. The mobile chip also excels in PassMark physics, scoring 1466 against 934, a 36.3% margin, and in floating-point math, where it posts 54105 versus 41036, a 24.2% lead. These wins indicate strengths in integer-heavy, cryptographic, and physics-simulation workloads, likely driven by its newer architecture and higher boost clock. The 1370P also leads in every Cinebench test, single-core and multi-core alike, with consistent margins around 6.3% to 6.5%.

Architecture Differences

The architectural gulf between these two processors is substantial. The 9900K is built on Intel's 14 nm process node, while the 1370P uses a 10 nm node, representing a full process generation improvement. The die sizes reflect this: the 9900K measures 180.3 mm², while the 1370P is larger at 217 mm², accommodating more transistors and a more complex design. The core counts differ dramatically—the 9900K has 8 cores and 16 threads, while the 1370P has 14 cores and 20 threads, reflecting Raptor Lake's hybrid architecture with performance and efficiency cores.

Cache hierarchies also diverge. The 9900K features 64 KB of L1 cache per core and 256 KB of L2 per core, culminating in 16 MB of shared L3 cache. The 1370P has 80 KB of L1 per core and a much larger 2 MB of L2 per core, with 24 MB of shared L3. This larger cache pool, combined with the newer node, likely contributes to the 1370P's superior performance in single-threaded and lightly-threaded tasks. The memory support differs as well: the 9900K supports only DDR4 with a dual-channel bus and a memory bandwidth of 42.7 GB/s, while the 1370P supports both DDR4 and DDR5 on a dual-channel bus, with no bandwidth figure listed in the data. PCIe capabilities are also upgraded on the 1370P, offering Gen 4 with 20 lanes versus Gen 3 with 16 lanes on the 9900K.

The integrated graphics are another point of divergence. The 9900K includes UHD Graphics 630, while the 1370P features Iris Xe Graphics 96EU, a more modern and capable iGPU. The sockets are incompatible, with the 9900K using Intel Socket 1151 and the 1370P using Intel BGA 1744, meaning these are not swappable in any system. The 9900K has an unlocked multiplier for overclocking, while the 1370P is locked, reflecting its mobile, power-constrained design. The TDPs tell this story clearly: the 9900K has a 95 W TDP, while the 1370P is rated at just 28 W.

Head-to-Head Benchmarks

The Cinebench suite shows a consistent, if modest, advantage for the 1370P across all versions. In Cinebench R15 multi-core, the 1370P scores 1649 against 1545, a 6.3% lead. Single-core R15 shows 232 versus 217, a 6.5% margin. This pattern repeats in R20, where multi-core results are 6873 versus 6439 (6.3%) and single-core is 970 versus 908 (6.4%). In R23, the multi-core scores are 16365 versus 15333 (6.3%) and single-core is 2310 versus 2164 (6.3%). The consistency of these margins, all hovering around 6%, suggests a fundamental architectural advantage rather than a workload-specific quirk.

The PassMark suite reveals more dramatic swings. Beyond the 9900K's three wins, the 1370P dominates in several categories. The largest margin is in data encryption, where the 1370P's 13067 score is more than double the 9900K's 6430, a 50.8% difference. Prime number finding shows a similar gap, with 97 versus 47, a 51.5% margin. Physics performance heavily favors the 1370P, with 1466 versus 934, a 36.3% lead. Floating-point math shows the 1370P ahead at 54105 versus 41036, a 24.2% margin. Integer math also favors the mobile chip, with 78675 versus 66134, a 15.9% lead. Multi-threaded performance in PassMark gives the 1370P a 20303 score against 18153, a 10.6% margin. Single-thread performance shows the 1370P at 3557 versus 2919, a 17.9% lead.

The 9900K's wins are equally decisive in the other direction. Its 53.7% lead in random string sorting is the largest single margin in either direction. The 47.9% advantage in extended instructions is similarly commanding. The 30.2% lead in data compression rounds out its victories. These three wins suggest that the 9900K's older architecture retains a specific edge in certain data-processing patterns, likely due to its higher base clock of 3.60 GHz versus the 1370P's 1900.00 MHz base clock, though the 1370P's boost clock of 5.20 GHz exceeds the 9900K's 5.00 GHz.

Specification Differences

The two processors diverge on nearly every specification field. The 9900K has 8 cores and 16 threads, while the 1370P has 14 cores and 20 threads. Base clocks are starkly different: 3.60 GHz for the 9900K versus 1900.00 MHz for the 1370P, reflecting the mobile chip's power management strategy. Boost clocks favor the 1370P at 5.20 GHz versus 5.00 GHz. TDP is a major differentiator, with 95 W for the desktop chip and 28 W for the mobile chip. The sockets are incompatible: Intel Socket 1151 versus Intel BGA 1744.

The cache specifications show the 1370P's advantage in L2 and L3 capacity, with 2 MB per core L2 versus 256 KB per core, and 24 MB shared L3 versus 16 MB. The 1370P also has a larger die at 217 mm² versus 180.3 mm². Memory support differs, with the 9900K limited to DDR4 and the 1370P supporting DDR4 and DDR5. The 9900K has a specified memory bandwidth of 42.7 GB/s, while the 1370P has no bandwidth figure listed. PCIe generations differ, with Gen 3 on the 9900K and Gen 4 on the 1370P, with 16 lanes versus 20 lanes.
