About the Intel Core i7-7700K CPU

The Intel Core i7-7700K is a 4-core (8-thread) processor built for the desktop CPU market. It launched in Q1 2017. It is part of Intel's Core i7 lineup, which is based on the Kaby Lake microarchitecture. The i7-7700K is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the HD 630 integrated graphics solution.

Memory and Cache

The Core i7-7700K supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-7700K 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 8 MB.

Cores and Clock Speeds

The Core i7-7700K features 4 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 4.2 GHz, and it can boost up to 4.5 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 i7-7700K includes an integrated graphics solution called HD 630. 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 i7-7700K has the 201st best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 31.93% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i9-7900X CPU

The Intel Core i9-7900X is an end-of-life 10-core (20-thread) processor built for the desktop CPU market. It launched in Q2 2017 with a suggested retail price of $999. It is part of Intel's Core i9 lineup, which is based on the X-Series 7th Gen microarchitecture. The i9-7900X is compatible with Intel Socket 2066 motherboards and is fabricated on Intel's 14 nm manufacturing process.

Memory and Cache

The Core i9-7900X supports DDR4 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Core i9-7900X 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 1 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 14 MB.

Cores and Clock Speeds

The Core i9-7900X 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 3.3 GHz, and it can boost up to 4.5 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 i9-7900X 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 i9-7900X has the 133rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 41.25% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 15,260 score and $999 launch price (MSRP) gives it a performance per dollar of 15.28. This is the 177th best in value for the 3DMark 11 Perf. Physics benchmark.
