Intel Pentium 4 HT 641

The Intel Pentium 4 HT 641 is an end-of-life 1-core (2-thread) processor built for the desktop CPU market. It launched in Q1 2006. It is part of Intel's Pentium 4 HT lineup, which is based on the Cedar Mill microarchitecture. The 4 HT 641 is compatible with Intel Socket 775 motherboards and is fabricated on Intel's 65 nm manufacturing process.

Memory and Cache

The Pentium 4 HT 641 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 4 HT 641 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 28 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 4 HT 641 is a single core CPU, but is able to 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 4 HT 641 does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
