Summary
About the AMD Athlon 650 CPU
The AMD Athlon 650 is an end-of-life 1-core (1-thread) processor built for the desktop CPU market. It launched in Q2 2000. It is part of AMD's Athlon Model 4 lineup, which is based on the Thunderbird microarchitecture. The 650 is compatible with AMD Socket A motherboards and is fabricated on a 180 nm manufacturing process.
Memory and Cache
The Athlon 650 supports DDR1 memory. In terms of cache, the Athlon 650 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 256 KB, is larger but slower than the L1.
Cores and Clock Speeds
The Athlon 650 is a single-core and single-threaded CPU, making it not capable of processing multiple computational tasks in parallel. The base clock speed of the CPU is 650.0 MHz. 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 650 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 Opteron 275 CPU
The AMD Opteron 275 is an end-of-life 2-core (2-thread) processor built for the server CPU market. It launched in Q2 2005. It is part of AMD's Opteron X2 lineup, which is based on the Italy microarchitecture. The Opteron 275 is compatible with AMD Socket 940 motherboards and is fabricated on a 90 nm manufacturing process.
Memory and Cache
In terms of cache, the Opteron 275 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 Opteron 275 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 2.2 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 Opteron 275 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
