About the AMD Ryzen 7 3700X CPU

The AMD Ryzen 7 3700X is a 8-core (16-thread) processor built for the desktop CPU market. It launched in Q3 2019 with a suggested retail price of $329. It is part of AMD's Ryzen 7 lineup, which is based on the Zen 2 microarchitecture. The 3700X is compatible with AMD Socket AM4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen 7 3700X supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 7 3700X 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 32 MB.

Cores and Clock Speeds

The Ryzen 7 3700X 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 4.4 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 7 3700X 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 7 3700X has the 89th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 49.43% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 18,283.5 score and $329 launch price (MSRP) gives it a performance per dollar of 55.57. This is the 35th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i5-8400 CPU

The Intel Core i5-8400 is an end-of-life 6-core (6-thread) processor built for the desktop CPU market. It launched in Q4 2017 with a suggested retail price of $182. It is part of Intel's Core i5 lineup, which is based on the Coffee Lake microarchitecture. The i5-8400 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 i5-8400 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-8400 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 9 MB.

Cores and Clock Speeds

The Core i5-8400 features 6 total cores which can process 6 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.8 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 locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core i5-8400 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 i5-8400 has the 262nd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 25.55% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 9,453 score and $182 launch price (MSRP) gives it a performance per dollar of 51.94. This is the 42nd best in value for the 3DMark 11 Perf. Physics benchmark.
