About the Intel Core i5-2500K CPU

The Intel Core i5-2500K is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q1 2011 with a suggested retail price of $216. It is part of Intel's Core i5 lineup, which is based on the Sandy Bridge microarchitecture. The i5-2500K is compatible with Intel Socket 1155 motherboards and is fabricated on Intel's 32 nm manufacturing process. It features the Intel HD 3000 integrated graphics solution.

Memory and Cache

The Core i5-2500K supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-2500K 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 6 MB.

Cores and Clock Speeds

The Core i5-2500K features 4 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 3.3 GHz, and it can boost up to 3.7 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 i5-2500K includes an integrated graphics solution called Intel HD 3000. 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 i5-2500K has the 363rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 17.76% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 6,571 score and $216 launch price (MSRP) gives it a performance per dollar of 30.42. This is the 118th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i7-6700 CPU

The Intel Core i7-6700 is an end-of-life 4-core (8-thread) processor built for the desktop CPU market. It launched in Q3 2015 with a suggested retail price of $303. It is part of Intel's Core i7 lineup, which is based on the Skylake microarchitecture. The i7-6700 is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the HD Graphics 530 integrated graphics solution and is bundled with a Yes cooler.

Memory and Cache

The Core i7-6700 supports DDR3, DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-6700 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.
