Intel Core i7-13705H vs Intel Core i9-11900 Comparison

The Intel Core i9-11900 and Intel Core i7-13705H are both 82nd-percentile processors, but they achieve that standing through entirely different means. The i9-11900 is a desktop part that wins every Cinebench test by roughly 19%, while the i7-13705H is a mobile chip that counters with wins in half of the Passmark tests, including a massive 47.3% lead in physics. The data suggests the i9-11900 is the pick for sustained multi-threaded rendering and single-core legacy workloads, while the i7-13705H suits floating-point math, encryption, and prime-number sieving. The i9-11900 takes 9 of 17 head-to-head benchmarks, but the i7-13705H’s wins are often by larger margins.

The Verdict

From the raw benchmark data, the Intel Core i9-11900 is the stronger all-around performer for desktop users who prioritize Cinebench workloads. It beats the i7-13705H by 18.7% in Cinebench R23 multi-core (18985 vs 15998) and by the same percentage in single-core (2680 vs 2258). This consistency across all six Cinebench tests — R15, R20, and R23, both single and multi-core — indicates a fundamental architectural advantage for the older desktop chip in rendering tasks. The i9-11900 also wins Passmark extended instructions by 24.3% and data compression by 4.2%, making it the better choice for code compilation and file archiving.

The i7-13705H, despite losing the overall benchmark count 8-9, is not a weak chip. Its Passmark physics score of 1854 is nearly double the i9-11900’s 977, a 47.3% advantage that suggests superior handling of real-time simulation. It also wins floating-point math by 22.4% (63064 vs 48948) and data encryption by 14.6% (16324 vs 13942). For mobile users doing scientific computing, cryptography, or physics simulations, the i7-13705H is the clear choice. Its 45W TDP versus the i9-11900’s 65W also makes it the more power-efficient option, though the i9-11900’s higher 5.20 GHz boost clock versus 5.00 GHz helps explain its single-core Cinebench wins.

The decision hinges on workload. The i9-11900 is the pick for desktop rendering, legacy software, and single-threaded productivity. The i7-13705H is the pick for mobile floating-point math, encryption, and physics workloads. Neither chip is objectively superior; the data shows a near-even split with 9 wins for the i9-11900 and 8 for the i7-13705H.

Architecture Differences

The two processors come from different Intel generations and are built for different sockets. The i9-11900 uses the Rocket Lake architecture on a 14 nm process node, while the i7-13705H uses Raptor Lake on a 10 nm node. The die sizes reflect this: the i9-11900 measures 276 mm², the i7-13705H is 257 mm². The i9-11900 is a desktop part on Intel Socket 1200, whereas the i7-13705H is a mobile processor on Intel BGA 1744.

Core counts diverge significantly. The i9-11900 has 8 cores and 16 threads, while the i7-13705H has 14 cores and 20 threads. The i7-13705H’s extra cores come with larger per-core caches: 80 KB L1 and 2 MB L2 per core versus the i9-11900’s 64 KB L1 and 512 KB L2. The i7-13705H also has more shared L3 cache at 24 MB versus 16 MB. This explains why the i7-13705H wins in multi-threaded Passmark tests despite losing Cinebench.

Memory support differs: the i9-11900 supports DDR4 only, while the i7-13705H supports both DDR4 and DDR5. The i9-11900 has a listed memory bandwidth of 51.2 GB/s; the i7-13705H’s bandwidth is not specified. PCIe capabilities also diverge, with the i9-11900 offering Gen 4 with 20 lanes (CPU only) versus the i7-13705H’s Gen 5 with 8 lanes (CPU only). Integrated graphics differ as well: the i9-11900 has UHD Graphics 750, while the i7-13705H has Iris Xe Graphics 96EU.

The i7-13705H is the newer part, released on 2023-01-03, versus the i9-11900’s 2021-03-15 release. The i9-11900 is end-of-life, while the i7-13705H is active. Both have locked multipliers, so neither supports overclocking. The i9-11900 has a launch MSRP of $439; the i7-13705H’s launch MSRP is $502.
