About the AMD Phenom II X4 820 CPU
The AMD Phenom II X4 820 is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q3 2009. It is part of AMD's Phenom II X4 lineup, which is based on the Deneb microarchitecture. The X4 820 is compatible with AMD Socket AM3 motherboards and is fabricated on GlobalFoundries's 45 nm manufacturing process.
Memory and Cache
The Phenom II X4 820 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Phenom II X4 820 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 128 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 4 MB.
Cores and Clock Speeds
The Phenom II X4 820 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 2.8 GHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.
Integrated Graphics
The Phenom II X4 820 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
