About the Intel Core i7-4960X CPU

The Intel Core i7-4960X is a 6-core (12-thread) processor built for the desktop CPU market. It launched in Q3 2013. It is part of Intel's Core i7 Extreme lineup, which is based on the Ivy Bridge-E microarchitecture. The i7-4960X is compatible with Intel Socket 2011 motherboards and is fabricated on Intel's 22 nm manufacturing process.

Memory and Cache

The Core i7-4960X supports DDR3 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Core i7-4960X 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 15 MB.

Cores and Clock Speeds

The Core i7-4960X features 6 total cores which can process 12 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.6 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 i7-4960X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance

The Core i7-4960X has the 201st best 3DMark 11 Performance Physics score among the 714 benchmarked CPUs in our database. It achieves 31.34% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X.

About the Intel Core i5-6400 CPU

The Intel Core i5-6400 is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q3 2015 with a suggested retail price of $182. It is part of Intel's Core i5 lineup, which is based on the Skylake microarchitecture. The i5-6400 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.

Memory and Cache

The Core i5-6400 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-6400 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 i5-6400 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 2.7 GHz, and it can boost up to 3.3 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 i5-6400 includes an integrated graphics solution called HD Graphics 530. 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 i5-6400 has the 375th best 3DMark 11 Performance Physics score among the 714 benchmarked CPUs in our database. It achieves 16.42% of the performance of the best benchmarked CPU, the AMD Ryzen 9 9950X. Its 6,283 score and $182 launch price (MSRP) gives it a performance per dollar of 34.52. This is the 100th best in value for the 3DMark 11 Perf. Physics benchmark.
