Summary
About the AMD Opteron 2356 CPU
The AMD Opteron 2356 is an end-of-life 4-core (4-thread) processor built for the server CPU market. It launched in Q2 2008 with a suggested retail price of $690. It is part of AMD's Opteron lineup, which is based on the Barcelona microarchitecture. The Opteron 2356 is compatible with AMD Socket Fr2 motherboards and is fabricated on a 65 nm manufacturing process.
Memory and Cache
The Opteron 2356 supports DDR2 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Opteron 2356 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 2 MB.
Cores and Clock Speeds
The Opteron 2356 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 2.3 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 Opteron 2356 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
About the Intel Xeon 6726P-B CPU
The Intel Xeon 6726P-B is a 42-core (84-thread) processor built for the server CPU market. It launched in Q1 2025 with a suggested retail price of $3,795. It is part of Intel's Xeon 6 lineup, which is based on the Granite Rapids-D microarchitecture. The 6726P-B is compatible with Intel BGA 4368 motherboards and is fabricated on Intel's 5 nm manufacturing process.
Memory and Cache
The Xeon 6726P-B supports DDR5 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously. In terms of cache, the Xeon 6726P-B has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 112 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 168 MB.
Cores and Clock Speeds
The Xeon 6726P-B features 42 total cores which can process 84 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.3 GHz, and it can boost up to 3.5 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 Xeon 6726P-B does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
