Intel Core i5-11600

The Intel Core i5-11600 is a 6-core, 12-thread desktop processor built on the Rocket Lake architecture for the Intel Socket 1200 platform. It occupies an 81st percentile position among all CPUs in the benchmark database, placing it firmly in the upper-middle tier of desktop processors despite being end-of-life. The data shows a well-rounded performer whose strengths and weaknesses are clearly defined by its dual 4.80 GHz boost clock and 65-watt TDP envelope.

Benchmark Performance

The Core i5-11600 delivers a Cinebench R23 multi-core score of 15,229 and a single-core score of 2,150. These results place it in a surprisingly tight cluster with its nearest rivals; the overall average benchmark score of 24,559 sits within a razor-thin margin of all four comparable processors listed in the database. The multi-core R23 result indicates a processor that can sustain heavy all-core workloads at a respectable level, but the more revealing figure is the R20 single-core score of 903, which outpaces its multi-core scaling in relative efficiency.

In Cinebench R15, the chip scores 1,535 in multi-core and 216 in single-core, while R20 produces 6,396 multi-core and 903 single-core. These numbers show consistent scaling across test generations, with the multi-core scores roughly seven times the single-core figures — a ratio that reflects the 6-core/12-thread configuration working in harmony. The PassMark suite reinforces this profile: a multi-thread score of 17,918 and a single-thread score of 3,284. The data compression test yields 218,062, while integer math hits 60,158 and floating-point math reaches 35,478.

The benchmark data indicates that the i5-11600 trades blows with its nearest rivals within a negligible 0.3% margin. It sits 0.2% ahead of the AMD Ryzen 5 8640U and the Intel Core Ultra 7 266V, while trailing the AMD Ryzen 5 7600X3D by 0.2% and the Intel Core i7-1360P by 0.3%. These are effectively statistical ties, meaning the i5-11600's real-world performance is indistinguishable from these newer parts in aggregate workloads. The PassMark extended instructions score of 15,698 suggests solid AVX-512 throughput, a hallmark of the Rocket Lake architecture that many competing chips lack.

Power and Thermals

The i5-11600 carries a 65-watt TDP, which classifies it as a mainstream power envelope rather than a high-performance or enthusiast-tier part. This figure is notable because the processor achieves its 4.80 GHz boost clock within that modest power budget. The 14 nm process node from Intel, with a die size of 276 mm², means the chip does not require exotic cooling solutions. A capable air cooler with a 120mm-class fan will comfortably handle this processor under sustained all-core loads, based on the thermal characteristics implied by the TDP class.

The 65-watt TDP also has practical implications for system builders. It allows for smaller power supply units and more compact chassis designs than would be possible with higher-wattage parts. The Rocket Lake architecture's 14 nm process runs warmer than smaller-node competitors per watt, but the 65-watt ceiling keeps heat density manageable. For a builder targeting a quiet system, the data suggests that a mid-range tower cooler will keep temperatures in check without aggressive fan curves. The locked multiplier means no overclocking headroom, so the thermal solution only needs to handle stock operation, which further simplifies cooling choices.

Who Should Consider It

The Core i5-11600 is a strong fit for productivity workloads that benefit from balanced single-thread and multi-thread performance. The Cinebench R23 multi-core score of 15,229 indicates it can handle video encoding, 3D rendering, and software compilation tasks with reasonable efficiency, though it will not compete with higher-core-count parts in heavily threaded workloads. The single-core R20 score of 903 makes it well-suited for applications that rely on per-core speed, such as legacy database operations and spreadsheet calculations.

For gaming, the PassMark physics score of 891 and single-thread score of 3,284 point to strong performance in game physics and game logic threads, which typically scale with single-core speed. The processor's 6-core/12-thread configuration is adequate for modern titles that use up to eight threads, but the data does not suggest it is optimized for the high-refresh-rate gaming segment where top-tier single-thread performance matters most. Office and web workloads will see no bottlenecks, as the R15 single-core score of 216 and PassMark single-thread score of 3,284 are well above the threshold for responsive daily use.

The processor is less ideal for users who run heavily multi-threaded professional workloads like 4K video editing or complex simulations, where the 12 MB shared L3 cache and 6-core layout may create constraints. The PassMark data encryption score of 11,060 and random string sorting score of 25,178 indicate decent but not exceptional performance in data-intensive tasks. Budget-conscious builders building a new system today should note the end-of-life status and the Intel Socket 1200 platform, which limits future upgrade paths.

How It Compares

AMD Ryzen 5 8640U: The i5-11600 edges out this mobile-oriented Ryzen part by 0.2% in average benchmark score. The desktop i5 achieves this with a 65-watt TDP, while the Ryzen 5 8640U is designed for lower-power mobile environments. In practice, the i5-11600 offers comparable performance in a desktop form factor, making it a viable alternative for builders who prefer Intel's platform features.

AMD Ryzen 5 7600X3D: This rival holds a 0.2% advantage over the i5-11600 in average score. The margin is negligible, but the Ryzen part's 3D V-Cache technology may provide advantages in cache-sensitive workloads that the benchmark averages do not fully capture. For general-purpose use, the two processors are effectively interchangeable in performance, with the i5-11600 offering a lower TDP class.

Intel Core Ultra 7 266V: The i5-11600 leads this newer Intel part by 0.2%. The Core Ultra 7 266V represents a different architecture generation, yet the benchmark data shows the older Rocket Lake chip holds its own. This suggests that the i5-11600's high boost clock and mature architecture still deliver competitive results against newer silicon.

Intel Core i7-1360P: The i7-1360P outperforms the i5-11600 by 0.3%, the largest margin among the rivals listed. The i7-1360P is a mobile processor with a different core configuration, but the benchmark data shows it is only marginally faster in aggregate. The i5-11600's desktop orientation with a 65-watt TDP provides a more predictable thermal environment for sustained workloads.

Single-Thread vs Multi-Thread Behavior

The i5-11600 exhibits a performance profile that is slightly weighted toward single-thread efficiency. The Cinebench R23 single-core score of 2,150 translates to a strong per-core capability, while the multi-core score of 15,229 yields a scaling ratio of approximately 7.1x from single to multi-core. This ratio is lower than the theoretical 6x from six cores, indicating that the processor does not achieve perfect linear scaling in multi-threaded workloads — a common outcome due to shared L3 cache and thermal/current limits.

The PassMark data reinforces this split. The single-thread score of 3,284 is competitive with much newer processors, while the multi-thread score of 17,918 reflects the 6-core limitation. The find prime numbers score of 56 is notably low, suggesting that this workload — which often stresses memory latency and branch prediction — is not a strong suit. Conversely, the integer math score of 60,158 and floating-point math score of 35,478 show solid arithmetic throughput that benefits from the 4.80 GHz boost clock.

For real-world use, this means the i5-11600 excels in applications where a single thread is the bottleneck, such as web browsing, document editing, and many game engines. Multi-threaded applications like video rendering or batch photo processing will see good but not exceptional performance, as the 6-core/12-thread layout is outclassed by higher-core-count alternatives. The 12 MB shared L3 cache is moderate for the era, and the dual-channel DDR4 memory bus with 51.2 GB/s bandwidth provides adequate data flow for the core count.
