8.2 Out of 10

The Intel Core i5 4670K is a Haswell processor sporting four cores, each clocked at 3.4GHz. The processor is also capable of sustaining up to four different threads, promising good performance. What is new about the 4670K, and differentiates it from its predecessor- the i5-3570K- is better power consumption, and it also offers better CPU performance, as well as improving on the GPU, than the 3570K, which is a good gaming processor in itself. Now the 4670K succeeds the 3570K and enters the CPU charts as another great gaming processor.

Reviews Word on the street for the Intel Core i5 4670K

But the 4670K has the same 3.4GHz baseclock and 3.8GHz Turbo as the old 3570K, with the same quad-core layout, and 6MB of Intel Smart Cache.

What People Are Saying Give it to me straight

Socket Type

Surely the 100MHz increments provided by the multiplier are good enough for everything bar bragging rights?
by Tech Radar
You get 20 execution units as opposed to 16, but that's still half the number of the really interesting Iris and Iris Pro graphics cores that Intel is restricting to other Haswell chips.
by Tech Radar
Our sources in the chip channel tell us that the new Haswell models are much more variable in terms of the speeds you can achieve with retail chips, which means most gaming systems are likely to be sold with a conservative 4.2GHz overclock at best.
by Tech Radar


The new Intel Core i5-4670K enters the CPU charts as our new favourite all-round gaming CPU.
by Tech Radar
You just can't feel 50MHz in-game and it's not going to shave significant time off a video encode job.
by Tech Radar


We're not overly distracted by the new base clock strap Intel has exposed for the K series models, either.
by Tech Radar
That leaves only clockspeeds and core counts to give them a chance of achieving a tangible performance improvement.
by Tech Radar


Better power consumption is always a good thing, but the savings are tiny for grid-connected appliances.
by Tech Radar


It gives a bit more flexibility, allowing you to hit some intermediate speeds you can't achieve with the CPU multiplier alone.

Hey guys! If you are intresting check out this build using i5 4670k !
Which can mean a lot when rendering 5000 players on a video game or working on photoshop...
Hi Anon, thanks for checking out our site. Did you see our comparison of the <a href="">fx 8350 vs 4670k</a>? We linked to it in the "read more" section just above the comments, and it compares the performance both single core and multi core and more between these two cpus. On this page, in the benchmarks section, we chose different CPUs to compare against for each benchmark, to try to show differences, e..g to give context to the 4670k's performance!
fucking bs they only show fx 8350 in single core performance.
