Intel Core i7-11600H vs Intel Core i7-9700K Comparison

The Intel Core i7-9700K and Intel Core i7-11600H represent two distinct design philosophies from Intel: a high-power desktop flagship from the Coffee Lake era versus a power-efficient mobile processor from Tiger Lake. The benchmark data reveals a clear split, with the desktop 9700K dominating in specific compute workloads while the mobile 11600H wins the majority of tests, 13 to 6. This head-to-head is less about raw capability and more about which workload characteristics—raw core count or modern instruction efficiency—matter more to the user.

Where Each One Wins

The Intel Core i7-9700K is the specialist for tasks that rely on extended instruction sets and memory bandwidth. Its most significant victory comes in PassMark's extended instructions test, where it scores 18,088 against the 11600H's 12,938, a massive 39.8% advantage. This suggests the older architecture's execution engine is better suited for AVX-type workloads. The 9700K also wins in data compression (208,062 vs 190,721, a 9.1% lead), random string sorting (25,756 vs 22,217, a 15.9% lead), and floating-point math (35,498 vs 32,963, a 7.7% lead). In Geekbench multicore, the 9700K scores 7,799 against 6,563 for the 11600H, an 18.8% win, likely driven by its two extra physical cores. Physics simulation also favors the desktop chip, with scores of 880 vs 763 (15.3% ahead).

The Intel Core i7-11600H counters with a sweeping victory in single-threaded performance and integer-heavy tasks. Its PassMark single-thread score of 3,019 beats the 9700K's 2,865 by 5.1%. The gap widens dramatically in integer math, where the 11600H scores 55,437 versus 41,411, a 25.3% advantage. The mobile chip also excels in data encryption, posting 9,718 against 4,590, a staggering 52.8% lead—likely due to newer cryptographic instructions. In the Cinebench suite, the 11600H wins every iteration (R15, R20, R23) in both single-core and multi-core tests, with a consistent 7.9% margin in most cases. The mobile chip also takes PassMark's multithread test (16,093 vs 14,414) and prime number finding (65 vs 52).

Architecture Differences

The fundamental split comes down to process node and core configuration. The 9700K uses Intel's 14 nm Coffee Lake process with a die size of 180.3 mm², while the 11600H is built on the 10 nm Tiger Lake-H node with a slightly larger 190 mm² die. The desktop chip features 8 cores and 8 threads with no hyper-threading, whereas the mobile chip has 6 cores and 12 threads, leveraging Hyper-Threading to reach higher thread counts. This explains why the 11600H wins multithreaded Cinebench despite having fewer physical cores—its 12 threads outperform the 9700K's 8 threads in these specific render workloads.

Cache hierarchies differ significantly. The 9700K provides 64 KB of L1 and 256 KB of L2 per core, with a shared 12 MB L3 cache. The 11600H offers 80 KB of L1 and a much larger 1.25 MB of L2 per core, plus an 18 MB shared L3 cache. The larger L2 and L3 caches on the mobile chip likely contribute to its integer and encryption advantages. Clock speeds also tell a story: the 9700K has a 3.60 GHz base and 4.90 GHz boost, while the 11600H operates at 2.50 GHz base and 4.60 GHz boost. The desktop chip's higher raw clocks help in floating-point and compression, but the mobile chip's architectural improvements overcome the clock deficit in most other areas.

The 11600H also supports PCIe Gen 4 with 20 lanes, while the 9700K is limited to PCIe Gen 3 with 16 lanes. Memory bandwidth is higher on the mobile part at 51.2 GB/s versus 42.7 GB/s, despite both using dual-channel DDR4. The 9700K pairs with UHD Graphics 630, while the 11600H includes UHD Graphics 750. The desktop chip has an unlocked multiplier, the mobile one does not. The 9700K is end-of-life, released in October 2018, while the 11600H remains active, launched in May 2021.

Head-to-Head Benchmarks

The Cinebench suite is the 11600H's domain. In Cinebench R23 multi-core, the mobile chip scores 13,286 against 12,238 for the 9700K, a 7.9% win. The single-core R23 result shows 1,875 vs 1,727, also a 7.9% lead. This pattern repeats in R20 (5,580 vs 5,139 multi-core; 787 vs 725 single-core) and R15 (1,339 vs 1,233 multi-core; 188 vs 174 single-core). The consistency of the 7.9% margin suggests a fundamental architectural efficiency advantage rather than a workload-specific quirk.

The 9700K's biggest counter-punch is in extended instructions. Its 18,088 score eclipses the 11600H's 12,938 by 39.8%, a decisive victory that shows the older chip's AVX2 capabilities remain potent. The desktop chip also dominates Geekbench multicore, scoring 7,799 versus 6,563, a 18.8% win. However, the 11600H reverses that in Geekbench single-core, winning 1,924 to 1,639, a 14.8% margin. This split highlights the 9700K's strength in scaling across its 8 cores versus the 11600H's superior per-core efficiency.

Encryption is the most lopsided result: the 11600H scores 9,718 versus 4,590, a 52.8% advantage. This is likely due to AES-NI improvements in Tiger Lake. Integer math also heavily favors the mobile chip (55,437 vs 41,411, 25.3% ahead), while the 9700K wins floating-point math (35,498 vs 32,963) and physics (880 vs 763). In PassMark multithread, the 11600H takes a 10.4% win (16,093 vs 14,414), showing its thread count advantage matters in this aggregate metric.

Specification Differences

The two processors diverge sharply on paper. The 9700K offers 8 cores and 8 threads; the 11600H has 6 cores and 12 threads. Base clocks differ by over a gigahertz: 3.60 GHz versus 2.50 GHz, with boost clocks at 4.90 GHz versus 4.60 GHz. The desktop chip has a 95 W TDP, while the mobile part is rated at 35 W, reflecting their different market segments. Sockets are incompatible: Intel Socket 1151 for the 9700K, Intel BGA 1787 for the 11600H.

Process technology separates them by node size: 14 nm versus 10 nm. The 11600H has larger per-core caches (80 KB L1, 1.25 MB L2) and a larger shared L3 (18 MB) compared to the 9700K's 64 KB L1, 256 KB L2, and 12 MB L3. PCIe support is newer on the mobile chip (Gen 4, 20 lanes) versus Gen 3, 16 lanes on the desktop. Memory bandwidth improves from 42.7 GB/s to 51.2 GB/s. The 9700K has an unlocked multiplier; the 11600H is locked. The launch MSRP for the 9700K was $385, while the 11600H launched at $395.
