About Intel Core i7-3840QM

The Intel Core i7-3840QM is a quad-core processor from the Ivy Bridge generation, leveraging a 22nm manufacturing process for improved efficiency. With eight threads via Intel's Hyper-Threading Technology, this CPU delivers robust multi-threading capabilities essential for multitasking and parallel workloads. Its base clock operates at 2.80 GHz, providing a solid foundation for consistent performance, while the processor can dynamically scale up to 3.80 GHz under lighter loads using Turbo Boost 2.0 technology. This frequency range allows it to handle both sustained computational tasks and bursty, single-threaded applications effectively. Benchmarks such as a Cinebench R23 single-core score of 708 points illustrate its competent per-core performance for its era. The chip's design reflects a focus on balancing raw processing power with platform integration for high-performance mobile workstations.

Power consumption is a critical aspect of this mobile CPU, defined by a 45 Watt Thermal Design Power (TDP) envelope. This TDP rating indicates the chip's thermal footprint, making it suitable for larger laptops and mobile workstations with adequate cooling solutions. The 22nm process technology contributed to a more power-efficient design compared to its predecessors, allowing for better performance-per-watt metrics. Despite its age, the i7-3840QM maintains relevance in scenarios where consistent multi-core throughput within a defined power budget is required. Its performance in multi-core benchmarks, such as achieving 5,020 points in Cinebench R23, demonstrates its historical capability for content creation and data processing. Efficient power management was key to deploying this level of performance in a mobile form factor.

The cache hierarchy of the 3840QM processor is structured around an 8 MB shared L3 cache, which is intelligently allocated across all four cores. This large, shared pool of high-speed memory reduces latency for frequently accessed data and improves inter-core communication. Coupled with the private L1 and L2 caches for each core, this architecture minimizes stalls and keeps the execution units fed with data. The cache subsystem is a significant contributor to the CPU's ability to achieve a Geekbench multi-core score of 2,111 points. This design effectively supported the demands of software benefiting from both high clock speeds and rapid data access, such as engineering simulations and financial modeling applications.

Best applications for the Intel Core i7-3840QM CPU include legacy professional software environments, light to moderate content creation, and computational analysis tasks. Its multi-threaded architecture makes it suitable for running multiple virtual machines, compiling code, or processing large datasets within spreadsheet software. The strong single-core turbo performance, evidenced by a 628-point Geekbench single-core result, ensures responsive performance in everyday office productivity suites. While outpaced by modern processors, this Ivy Bridge chip remains a competent performer for specific, stabilized business systems where platform longevity is valued. Its balanced profile of clock speed, core count, and manageable power consumption made it a defining mobile processor for its time.
