Intel Pentium 4 521 2.80 GHz desktop processor OEM

SKU CH-CNQ1-9TF6D

Single-core desktop processor running at 2.80 GHz with 1 MB L2 cache for Socket T LGA-775 systems

  • Processors TypeDesktop
  • Single-core design handles basic computing tasks efficiently
  • 80 GHz clock speed delivers responsive performance for everyday applications
  • 1 MB L2 cache reduces memory latency for smoother operation
  • 64-bit processing capability supports modern operating systems and software
  • 90 nm manufacturing process with 84 W thermal design fits Socket T LGA-775 motherboards

Pentium 4 521 single-core 2.80 GHz

This Intel Pentium 4 521 desktop processor runs at 2.80 GHz on a 90 nm process with 1 MB L2 cache. It uses the LGA 775 socket and provides 64-bit processing capability. The OEM package includes the processor only.

Suits legacy LGA 775 maintenance

This CPU fits existing Socket T motherboards needing a direct replacement. It is not suited for multi-threaded applications, modern operating systems or tasks requiring multiple cores. Buyers building new systems should consider current platforms.

1 MB L2 cache and 2.80 GHz clock speed

The single core handles simple office tasks, legacy software and light embedded workloads within its 84 W thermal envelope. Performance runs out quickly with concurrent processes, modern browsers or any multi-threaded demand.

Questions sur cet article

Will this CPU fit my LGA 775 motherboard?

Yes, the Pentium 4 521 uses the Socket T LGA-775 interface, so it installs directly into any motherboard with that socket.

What does the 90 nm figure mean for my build?

The 90 nm process indicates the transistor size; it generally correlates with the processor's thermal characteristics and power draw for a 2.80 GHz single-core design.

Is a cooler included in the OEM pack?

OEM packaging typically contains only the processor itself; a compatible LGA-775 heatsink and fan must be sourced separately.
