About the AMD Ryzen 9 3900X CPU

The AMD Ryzen 9 3900X is a 12-core (24-thread) processor built for the desktop CPU market. It launched in Q3 2019 with a suggested retail price of $499. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 2 microarchitecture. The 3900X is compatible with AMD Socket AM4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen 9 3900X supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 3900X 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 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 64 MB.

Cores and Clock Speeds

The Ryzen 9 3900X features 12 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.8 GHz, and it can boost up to 4.6 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 Ryzen 9 3900X 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 Ryzen 9 3900X has the 80th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 51.18% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 18,932 score and $499 launch price (MSRP) gives it a performance per dollar of 37.94. This is the 86th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i7-8086K CPU

The Intel Core i7-8086K is an end-of-life 6-core (12-thread) processor built for the desktop CPU market. It launched in Q2 2018 with a suggested retail price of $425. It is part of Intel's Core i7 40th lineup, which is based on the Coffee Lake microarchitecture. The i7-8086K 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 i7-8086K supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-8086K 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 12 MB.

Cores and Clock Speeds

The Core i7-8086K 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 4.0 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 i7-8086K 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 i7-8086K has the 209th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 31.23% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 11,554 score and $425 launch price (MSRP) gives it a performance per dollar of 27.19. This is the 134th best in value for the 3DMark 11 Perf. Physics benchmark.
