About the Intel Core i7-6650U CPU

The Intel Core i7-6650U is a 2-core (4-thread) processor built for the mobile CPU market. The i7-6650U is compatible with FCBGA1356 motherboards and is fabricated on a 14 nm manufacturing process. It features the Intel Iris Graphics 540 integrated graphics solution.

Memory and Cache

In terms of cache, the Core i7-6650U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 128 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 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 i7-6650U 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 2200.0 MHz, and it can boost up to 3400.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Core i7-6650U includes an integrated graphics solution called Intel Iris Graphics 540. 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

The Core i7-6650U has the 410th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 13.30% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i5-5257U CPU

The Intel Core i5-5257U 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 i5-5257U is compatible with Intel BGA 1168 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the Intel Iris 6100 integrated graphics solution.

Memory and Cache

The Core i5-5257U supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-5257U 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 3 MB.

Cores and Clock Speeds

The Core i5-5257U 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 2.7 GHz, and it can boost up to 3.1 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 i5-5257U includes an integrated graphics solution called Intel Iris 6100. 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 i5-5257U has the 465th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 10.54% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 3,898 score and $315 launch price (MSRP) gives it a performance per dollar of 12.37.
