Summary
About the AMD Athlon II X3 455 CPU
The AMD Athlon II X3 455 is an end-of-life 3-core (3-thread) processor built for the desktop CPU market. It launched in Q4 2010. It is part of AMD's Athlon II X3 lineup, which is based on the Rana microarchitecture. The X3 455 is compatible with AMD Socket AM3 motherboards and is fabricated on a 45 nm manufacturing process.
Memory and Cache
The Athlon II X3 455 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Athlon II X3 455 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.
Cores and Clock Speeds
The Athlon II X3 455 features 3 total cores which can process 3 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.3 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 Athlon II X3 455 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
About the AMD Athlon X2 450 CPU
The AMD Athlon X2 450 is an end-of-life 2-core (2-thread) processor built for the desktop CPU market. It launched in Q3 2014. It is part of AMD's Athlon lineup, which is based on the Kaveri microarchitecture. The X2 450 is compatible with AMD Socket FM2+ motherboards and is fabricated on GlobalFoundries's 28 nm manufacturing process.
Memory and Cache
The Athlon X2 450 supports DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Athlon X2 450 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 1 MB, is larger but slower than the L1.
Cores and Clock Speeds
The Athlon X2 450 features 2 total cores which can process 2 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel.
