About the Intel Pentium D 940 CPU

The Intel Pentium D 940 is an end-of-life 2-core (2-thread) processor built for the desktop CPU market. It launched in Q1 2006 with a suggested retail price of $423. It is part of Intel's Pentium D lineup, which is based on the Presler microarchitecture. The D 940 is compatible with Intel Socket 775 motherboards and is fabricated on Intel's 65 nm manufacturing process.

Memory and Cache

The Pentium D 940 supports DDR1, DDR2, DDR3 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Pentium D 940 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 16 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1.

Cores and Clock Speeds

The Pentium D 940 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 3.2 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 Pentium D 940 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 2356 (B3) CPU

The AMD Opteron 2356 (B3) 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.
