About the Intel Core i9-9900K CPU

The Intel Core i9-9900K is an end-of-life 8-core (16-thread) processor built for the desktop CPU market. It launched in Q4 2018 with a suggested retail price of $488. It is part of Intel's Core i9 lineup, which is based on the Coffee Lake Refresh microarchitecture. The i9-9900K is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 630 integrated graphics solution.

Memory and Cache

The Core i9-9900K supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-9900K 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 16 MB.

Cores and Clock Speeds

The Core i9-9900K features 8 total cores which can process 16 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 5.0 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 i9-9900K includes an integrated graphics solution called UHD Graphics 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 & Value

The Core i9-9900K has the 104th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 46.67% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 17,264 score and $488 launch price (MSRP) gives it a performance per dollar of 35.38. This is the 99th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i5-6600T CPU
