Intel Core i5-3570 3.40 GHz desktop processor

SKU CH-90GT-4JGHE

Quad-core desktop processor running at 3.40 GHz with a 3.80 GHz turbo speed, 6 MB cache, 77 W TDP and LGA 1155 socket

  • TDP rating77 W
  • Processor classDesktop
  • Quad-core design handles multitasking smoothly with four processing cores
  • 40 GHz base clock delivers responsive everyday performance
  • Turbo frequency reaches 3.80 GHz for demanding workload bursts
  • 22 nm manufacturing enables efficient 77 W thermal design
  • LGA 1155 socket fits compatible motherboards for straightforward upgrades

Ideal for 3rd gen LGA-1155 builds

The Intel Core i5-3570 is a 22 nm desktop processor with four cores running at 3.40 GHz. It fits the LGA-1155 socket and carries a 77 W thermal design power. This CPU suits system builders refreshing an existing platform or assembling a budget workstation from compatible parts.

6 MB cache and 3.80 GHz peak

Six megabytes of shared cache feed the four cores for everyday multitasking and light content creation. The chip can reach 3.80 GHz when thermal headroom allows, giving a measurable lift in single-threaded workloads. Under sustained all-core loads the 77 W envelope limits how long the higher frequency can be maintained.

Drop-in upgrade for dual-core LGA-1155 CPUs

Replacing an older two-core Sandy Bridge or early Ivy Bridge part with this quad-core i5-3570 adds two full threads and the larger 6 MB cache. The jump is worth it when the motherboard already supports 22 nm processors and the user needs smoother background task handling without changing platform.

Questions about this item

Will the Core i5-3570 drop into my existing LGA-1155 board without a BIOS update?

The processor uses the LGA-1155 socket, so it fits the same physical slot as other CPUs on that platform; whether a BIOS update is needed depends on the motherboard vendor and the board's current firmware.

How can I confirm the CPU is running at its rated 3.40 GHz base and 3.80 GHz turbo speeds after installation?

Open Task Manager or a hardware monitor such as CPU-Z and watch the core frequency readout under load; it should sit at 3.40 GHz at stock settings and climb toward 3.80 GHz when thermal headroom allows.

Does the retail box include a cooler, or do I need to buy one separately for the 77 W TDP?

The boxed version of the Core i5-3570 ships with Intel's stock cooler rated for the 77 W thermal design power; an aftermarket cooler is only required if you prefer quieter operation or lower temperatures.
