About the Intel Core i7-6950X CPU

The Intel Core i7-6950X is an end-of-life 10-core (20-thread) processor built for the desktop CPU market. It launched in Q2 2016 with a suggested retail price of $1,723. It is part of Intel's Core i7 Extreme lineup, which is based on the Broadwell-E microarchitecture. The i7-6950X is compatible with Intel Socket 2011-3 motherboards and is fabricated on Intel's 14 nm manufacturing process.

Memory and Cache

The Core i7-6950X supports DDR4 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Core i7-6950X 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 25 MB.

Cores and Clock Speeds

The Core i7-6950X features 10 total cores which can process 20 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.0 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 unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Core i7-6950X does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance & Value

The Core i7-6950X has the 113th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 44.34% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 16,403 score and $1,723 launch price (MSRP) gives it a performance per dollar of 9.52. This is the 200th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i5-11600K CPU

The Intel Core i5-11600K is an end-of-life 6-core (12-thread) processor built for the desktop CPU market. It launched in Q1 2021 with a suggested retail price of $262. It is part of Intel's Core i5 lineup, which is based on the Rocket Lake-S microarchitecture. The i5-11600K is compatible with Intel Socket 1200 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 750 integrated graphics solution.

Memory and Cache

The Core i5-11600K supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-11600K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 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 12 MB.

Cores and Clock Speeds

The Core i5-11600K 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 3.9 GHz, and it can boost up to 4.9 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 i5-11600K includes an integrated graphics solution called UHD Graphics 750. 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 i5-11600K has the 114th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 44.28% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 16,381 score and $262 launch price (MSRP) gives it a performance per dollar of 62.52. This is the 29th best in value for the 3DMark 11 Perf. Physics benchmark.
