Intel Core i7-1370P vs Intel Core i9-11900K Comparison

The Intel Core i7-1370P and Intel Core i9-11900K represent two very different design philosophies from Intel, one a power-sipping mobile processor and the other a desktop flagship. Benchmark data shows the i9-11900K dominates the raw performance charts, winning 12 of the 17 head-to-head comparisons, but the i7-1370P is far from a pushover, claiming victory in 5 tests and often by significant margins. Both CPUs sit at the 79th percentile among all processors, with average benchmark scores of 26,900 for the i7-1370P and 26,639 for the i9-11900K, placing them in nearly identical overall performance tiers despite their architectural and market differences.

Head-to-Head Benchmarks

The i9-11900K’s advantage in multi-core workloads is consistent and decisive across all Cinebench versions. In Cinebench R23 multi-core, the i9-11900K scores 21,168 against the i7-1370P’s 16,365, a 22.7% edge. That same 22.7% delta appears in Cinebench R15 and R20 multi-core, with scores of 2,133 versus 1,649 and 8,890 versus 6,873 respectively. Single-core Cinebench results tell a similar story: the i9-11900K leads by 22.7% in R15 (300 vs 232) and R23 (2,988 vs 2,310), and by 22.6% in R20 (1,254 vs 970). These are substantial margins that leave little ambiguity about which chip is faster in rendering workloads.

The gap widens further in certain PassMark tests. The most dramatic difference appears in extended instructions, where the i9-11900K scores 23,406 versus 12,822 for the i7-1370P, a massive 45.2% advantage. Random string sorting also favors the desktop chip heavily, with the i9-11900K posting 37,942 against 23,580, a 37.9% delta. Data compression shows a 34.2% lead for the i9-11900K (330,836 vs 217,676), and multithread performance is 18.9% higher (25,038 vs 20,303). Even integer math, a strong suit for the mobile chip, goes to the i9-11900K by 11.9% (89,279 vs 78,675).

However, the i7-1370P secures several notable wins that demonstrate its strengths in specific task types. The standout result is in find prime numbers, where the i7-1370P scores 97 against 68 for the i9-11900K, a 42.6% victory. Physics simulation also leans heavily toward the mobile chip, with the i7-1370P scoring 1,466 versus 1,052, a 39.4% advantage. In floating-point math, the i7-1370P edges out the i9-11900K by 2.4% (54,105 vs 52,841). Single-thread performance is essentially a tie, with the i7-1370P leading by a slim 1.3% in both PassMark single-thread tests (3,557 vs 3,511). Data encryption also goes to the i9-11900K, but by a smaller 18.3% margin (16,000 vs 13,067).

Architecture Differences

The two processors are built on fundamentally different foundations. The i7-1370P uses Intel’s Raptor Lake architecture on a 10 nm process node, while the i9-11900K is a Rocket Lake part on a 14 nm node. This process advantage helps the mobile chip pack more cores into a smaller footprint, with the i7-1370P’s die size measuring 217 mm² compared to 276 mm² for the i9-11900K.

Core counts diverge sharply. The i7-1370P features 14 cores and 20 threads, while the i9-11900K has 8 cores and 16 threads. Cache layouts also differ significantly. Both share 80 KB of L1 cache per core, but the i7-1370P has 2 MB of L2 cache per core versus 512 KB per core for the i9-11900K. The L3 cache favors the newer chip as well: 24 MB shared for the i7-1370P versus 16 MB shared for the i9-11900K.

Clock speeds tell a different story. The i9-11900K has a higher base clock at 3.50 GHz versus 1.90 GHz for the i7-1370P, and a marginally higher boost clock at 5.30 GHz versus 5.20 GHz. The desktop chip also has a much higher thermal envelope at 125 W TDP compared to 28 W for the mobile part. Both processors use dual-channel memory, but memory support differs: the i7-1370P supports DDR4 and DDR5, while the i9-11900K is limited to DDR4. The i9-11900K lists a memory bandwidth of 51.2 GB/s, while the i7-1370P does not specify one. Both offer PCIe Gen 4 with 20 lanes from the CPU.

Integrated graphics separate them further. The i7-1370P includes Iris Xe Graphics with 96 execution units, while the i9-11900K has UHD Graphics 750. The i7-1370P is a mobile segment chip on Intel BGA 1744, and the i9-11900K is a desktop processor on Intel Socket 1200. The i9-11900K has an unlocked multiplier, while the i7-1370P does not. Production status also differs: the i7-1370P is active, while the i9-11900K is end-of-life.

Where Each One Wins

The i9-11900K is the clear choice for multi-threaded productivity workloads that scale with core count and raw throughput. Its victories in all three Cinebench multi-core tests, data compression, encryption, extended instructions, integer math, and random string sorting make it the stronger option for rendering, file archiving, code compilation, and heavy number-crunching tasks. The 45.2% lead in extended instructions is particularly telling for workloads that leverage SIMD and specialized instruction sets.

The i7-1370P, despite being a mobile chip with a 28 W TDP, wins in tasks that favor its newer architecture and larger L2/L3 cache. The 42.6% lead in find prime numbers suggests strong performance in prime-finding algorithms and related workloads. Physics simulation, where it leads by 39.4%, points to advantages in certain scientific or gaming physics calculations. The floating-point math win, however slight at 2.4%, and the near-tie in single-thread performance, where it leads by 1.3%, indicate that the i7-1370P is no slouch in lighter, latency-sensitive tasks.

For users prioritizing raw multi-core performance in a desktop environment with an unlocked multiplier for overclocking, the i9-11900K is the data-backed choice. For those needing strong performance in a mobile form factor with significantly lower power draw, the i7-1370P offers competitive single-thread and physics performance, plus wins in prime number calculations and floating-point math.

The Verdict

The data paints a clear picture: the Intel Core i9-11900K is the faster processor in the majority of benchmark tests, winning 12 of 17 comparisons and holding decisive leads in rendering, compression, encryption, and extended instruction workloads. Its 22.7% advantage across all Cinebench tests makes it the superior choice for multi-threaded desktop productivity. The i7-1370P, however, counters with wins in prime numbers (42.6% ahead), physics (39.4% ahead), and floating-point math, plus a marginal single-thread edge, all while consuming far less power and fitting into a mobile socket.

Users building a desktop workstation or gaming rig that prioritizes maximum multi-core throughput should choose the i9-11900K based on benchmark results. Those requiring a mobile processor for a laptop or compact system, or who value the newer Raptor Lake architecture with more cores, larger caches, and DDR5 support, should select the i7-1370P. The i9-11900K is end-of-life and has a launch MSRP of $539, while the i7-1370P is active with a launch MSRP of $438. Both chips sit at the same 79th percentile, but the i9-11900K delivers more raw performance where it matters most in the benchmark suite.
