About the AMD A6-6400K CPU
The AMD A6-6400K is an end-of-life 2-core (2-thread) processor built for the desktop CPU market. It launched in Q2 2013. It is part of AMD's A6 lineup, which is based on the Richland microarchitecture. The A6-6400K is compatible with AMD Socket FM2 motherboards and is fabricated on GlobalFoundries's 32 nm manufacturing process. It features the Radeon HD 8470D integrated graphics solution.
Memory and Cache
The A6-6400K supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the A6-6400K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1 MB, is larger but slower than the L1.
Cores and Clock Speeds
The A6-6400K features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.9 GHz, and it can boost up to 4.1 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 A6-6400K includes an integrated graphics solution called Radeon HD 8470D. 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 A6-6400K has the 615th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 5.40% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the Intel Core i7-12700 CPU
The Intel Core i7-12700 is a 12-core (20-thread) processor built for the desktop CPU market. It launched in Q1 2022 with a suggested retail price of $349. It is part of Intel's Core i7 lineup, which is based on the Alder Lake-S microarchitecture. The i7-12700 is compatible with Intel Socket 1700 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution and is bundled with a Laminar RM1 cooler.
Memory and Cache
The Core i7-12700 supports DDR4-3200, DDR5-4800 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-12700 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 1.25 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 25 MB.
Cores and Clock Speeds
The Core i7-12700 features 12 total cores which can process 20 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 12 cores consist of 8 P-Cores and 4 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 2.1 GHz, and it can boost up to 4.9 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 i7-12700 includes an integrated graphics solution called UHD Graphics 770. 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 i7-12700 has the 16th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database.
