Intel Pentium G3258 

Released April, 2014
  • 3.2 GHz
  • Dual core
  • Unlocked
8.3 Out of 10

Pairing it with something like the R9 280X and a 1920x1080 monitor will make for a really awesome gaming system that will offer strong performance and won't break the bank.

This is because the gaming industry has moved on from the last overclockable dual core Intel CPU - games can now take advantage of more cores, and that jump from 2 cores to hyperthreading lets a high end title stretch its legs a little more than a simple overclock.

How can you make your Pentium G3258 system cheaper? Run Ubuntu!

by Jeremy Hellstrom |
When they benchmarked the CPU the lack of Advanced Vector Extensions and the fact that it is a dual core CPU showed in the results but when you consider the difference in price for a G3258's compared to a 4770K it fares quite well.
Phoronix tested out the 20th Anniversary Pentium CPU on Ubuntu 14.10 and right off the bat were impressed as they managed a perfectly stable overclock of 4.4GHz on air.
With some strong overclocking potential on the budget friendly G3258, we're expecting some strong gains in overall performance.
Overall, the G3258 is a really cool and fun processor from Intel.
Heading into the BIOS of our ASRock Z97X Killer, we move straight over to the multiplier section to see just what kind of overclock we're able to achieve.
Of course, we'd be disappointed if we had those kinds of temperatures, since we don't have that kind of performance.
As long as the user is not thermally limited, there seems to be a big bump where the amount of voltage needed to increase the frequency by 100 MHz is significantly higher than before.
Having a lack of cores can really damage frame rates in some titles, especially when the amount of GPUs starts to rise.

what is passmark on 1 core when is cpu OC?
This processor is powerful the fx 8350 and gaming! 2 Intel cores win 8 AMD cores.
