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 AMD A10-7850K CPU
The AMD A10-7850K is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q1 2014. It is part of AMD's A10 lineup, which is based on the Kaveri microarchitecture. The A10-7850K is compatible with AMD Socket FM2+ motherboards and is fabricated on GlobalFoundries's 28 nm manufacturing process. It features the Radeon R7 integrated graphics solution.
Memory and Cache
The A10-7850K supports DDR3 memory. In terms of cache, the A10-7850K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 256 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 4 MB, is larger but slower than the L1.
Cores and Clock Speeds
The A10-7850K 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 3.7 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 A10-7850K includes an integrated graphics solution called Radeon R7. 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 A10-7850K has the 455th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 10.76% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
