About the Intel Core i7-640M CPU

The Intel Core i7-640M is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2010 with a suggested retail price of $346. It is part of Intel's Core i7 lineup, which is based on the Arrandale microarchitecture. The i7-640M is compatible with Intel BGA 1288 motherboards and is fabricated on Intel's 32 nm manufacturing process. It features the HD Graphics (Ironlake) integrated graphics solution.

Memory and Cache

The Core i7-640M supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-640M 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 4 MB.

Cores and Clock Speeds

The Core i7-640M features 2 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.8 GHz, and it can boost up to 3.5 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core i7-640M includes an integrated graphics solution called HD Graphics (Ironlake). 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 i7-640M has the 500th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 9.07% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 3,356 score and $346 launch price (MSRP) gives it a performance per dollar of 9.7. This is the 196th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i5-5250U CPU

The Intel Core i5-5250U is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q1 2015 with a suggested retail price of $315. It is part of Intel's Core i5 lineup, which is based on the Broadwell-U microarchitecture. The i5-5250U is compatible with Intel BGA 1168 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel HD 6000 integrated graphics solution.
