  • Socket 1155
  • Number of cores 4
  • Clock rate 3.4 GHz
  • Cache 6 MB
  • Thermal Design Power 77 W
  • Technology 22 nm
The Core i5 3570K is a scaled-down version of Intel's Core i7 3770K, using the same Ivy Bridge architecture, 22 nm design, new Tri-Gate transistors and Intel HD Graphics 4000 onboard graphics processing.

The Core i5 3570K is cheaper than the Core i7 3770K. It has four physical cores but there's no Hyper-Threading function. However, a Turbo mode is still on hand to adjust the clock speed from 3.4 (base frequency) to 3.8 GHz (maximum Turbo frequency) in relation to workload in the various cores. Here, there's 6 MB of L3 cache compared with 8 MB in the higher-end model. The cache is shared between the cores.

These differences reduce performances by 13% compared with the Core i7 3770K. That makes the Core i5 3570K a decent processor that comes in just behind the Core i7 2600K and Core i7 2700K previous-generation Sandy Bridge CPUs. However, the Core i5 out-performs the AMD FX-8150 by over 13%.

That said, we did notice something quite strange when testing this CPUs power use, which turned out to be higher—both at idle and when active—than the Core i7 3770K. We were expecting to see the opposite.

For more detailed information on Intel's Ivy Bridge processors, see our review of the, Intel Core i7 3770K. Here you'll find an overview of functions such as the Turbo mode and Hyper-Threading, as well as a review of the built-in graphics processor's performances.

See Performance Index Table


  • Performances in applications and games
  • Turbo mode
  • Low power use
  • Much faster onboard graphics


  • Graphics processing is faster but still isn't good enough to replace a stand-alone graphics card—even an entry-level card!


Intel has confirmed its status as leader in the market for desktop computer CPUs with a new generation of processors that are faster and less power-hungry than their predecessors. Although the gain in performance isn't enormous, it's certainly still beneficial. However, with no real competitors at this performance level, the price could stay quite high for quite some time.
