About the Intel Core i7-4940MX CPU

The Intel Core i7-4940MX is an end-of-life 4-core (8-thread) processor built for the mobile CPU market. It launched in Q1 2014 with a suggested retail price of $1,096. It is part of Intel's Core i7 Extreme lineup, which is based on the Haswell microarchitecture. The i7-4940MX is compatible with Intel Socket G3 motherboards and is fabricated on Intel's 22 nm manufacturing process. It features the Intel HD 4600 integrated graphics solution.

Memory and Cache

The Core i7-4940MX supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-4940MX has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 8 MB.

Cores and Clock Speeds

The Core i7-4940MX features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.1 GHz, and it can boost up to 4.0 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Core i7-4940MX includes an integrated graphics solution called Intel HD 4600. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.

Benchmark Performance & Value

The Core i7-4940MX has the 264th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 25.42% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 9,402 score and $1,096 launch price (MSRP) gives it a performance per dollar of 8.58. This is the 204th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i9-12900HX CPU
