INTEL CORE i5-13600K Review

As if Intel’s Core I5-13600K wasn’t already attractive enough when we first reviewed this chip, it’s also received a price cut since our first review, meaning it now sits at just £ inc VAT. Both the Ryzen 7 77OOX and Ryzen 7 7700 cost about the same amount, while the Ryzen 5 7600X costs significantly less and the Core i7-13700K costs £ more, so these three CPUs are very much up against each other at the moment, courtesy of AMD’s recent price cuts. Read our INTEL CORE i5-13600K Review.

As well as having a peak stock-speed P-Core frequency of 5.1GHz, which is a 200MHz advantage over its predecessor, we found it could also achieve this frequency over all its P-Cores in multi-threaded workloads, while the peak 3.9GHz E-Core boost clock was being applied over all those cores too.

The Core i5-13600K is also a fullfat Raptor Lake CPU, with 20MB of L2 cache, plus has four more E-Cores than the Core i5-12600K, as well as 4MB of extra L3 cache.

Not only that, but this chip is becoming a favourite among enthusiasts, as its also a decent overclocker, hitting 5.7GHz across all its P-Cores with 1.35V, although temperatures and power consumption do rise as a result. Still, it wasn’t particularly hard to cool at stock speed, with our water-cooling system returning temperatures in the mid-70s (°C) under load, showing there’s plenty of headroom for using less powerful coolers.

Starting with the RealBench tests, the Core i5-13600K was outdone by all the Ryzen 7000-series CPUs in the image editing test, which stresses lightly threaded performance. However, it came out swinging elsewhere, beating both the Ryzen 7 77OOX and Ryzen 7 7700 in our heavily multi-threaded video encoding test and coming close to matching the more expensive Ryzen 9 7900 too. The system score of 372,186 again beat the two Ryzen 7 chips and satjust below the Ryzen 9 7900’s result.

It nearly matched the latter in Cinebench too, and massively outstripped the Ryzen 7 7700X here, offering massively more performance than the Core i5-12600K in the process. It was also fasterthan any of AMD’s chips short of the Ryzen 7 5800X3D in Far Cry 6, and only the Ryzen 7 7700X was quicker in Watch Dogs: Legion too.

Once overclocked, it was a convincing win for the Core i5-13600K over the Ryzen 7 7700X, and it even beat the Ryzen 9 7900’s stock speed Cinebench score in addition to bettering it in games and image editing. It also beat the similarly priced Ryzen 7 5800X3D in our game benchmarks. On the downside, power consumption was high at stock speed, eclipsing the Ryzen 9 7900X and even the Ryzen 9 7950X once overclocked.


While it might not be the most power-frugal option, the Core i5-13600K is one of the fastest chips available in many tasks, despite its reasonable price tag. Its quick out of the box, matching or bettering AMD’s Ryzen 7-series CPUs, and once overclocked, its a monster that punches well above its weight.

The most attractive quality is its versatility. It’s good at every task, and rarely far behind more expensive options, fulfilling the remit of a Core i5 chip brilliantly. If you need an affordable gaming CPU, that’s also a multithreaded performance beast when you need it, this is the best all-round option.

Editor choice INTEL CORE i5-13600K Review

Great at stock speed, and even better when overclocked. This is a superb all-round CPU for both gaming and multi-threaded workloads.

  • Excellent overclocking potential
  • Great all-round performance for the cash
  • Reasonable temperatures
  • Can be power-hungry
  • New AMD chips are faster in some lightly threaded loads
  • Ryzen 7 5800X3D quicker in some games
