Intel is celebrating its 20th Anniversary by offering an unlocked Pentium processor to budget users. Pentium G3258 is the first in the series with an unlocked multiplier for overclocking. Friends at Coolaler managed to get their hands on an engineering sample and checked out its overclocking potential. To our surprise, this Haswell SKU reached 4.7 GHz on air which is quite astonishing. Overclocked performance of Pentium G3258 is on par and slightly lower than Core i3 4340U in some benchmarks. Benchmarks show that Pentium G3258 has a great price:performance ratio.
Intel Pentium G3258 Specifications
Pentium G3258 is a dual core processor with two threads and 3 MB L3 cache. It comes with a 3.2 GHz base frequency but does not support Intel’s Turbo Boost technology. Pentium G3258 supports DDR3-1333 MHz memory and has a max TDP of 53 W. CPU-Z recognized the processor as G3420 but the correct model name is display in the specifications area. The engineering sample used in these testings is made in Costa Rica which indicates that it might be one of the lucky cherry picked ones.
Intel Pentium G3258 Overclocking
Coolaler overclocked the CPU in two stages. First they tried the average overclocking number of 4.5 GHz which the Pentium G3258 easily reached. This showed a nice potential for the processor to reach beyond that on air thanks to the unlocked multiplier and voltage regulation.
Apart from Sandy Bridge processors, we havent seen any good overclocking processors stable at 5 GHz be it Ivy Bridge or Haswell. Intel only allows overclocking on Z87 and Z97 chipset motherboards but manufacturers have unlocked overclocking in H97, H87, H85 and H81 chipset motherboards as well through a BIOS update.
Intel Pentium G3258 Benchmarks
Coolaler used MSI’s Z97M Gaming motherboard and AMD R7 260X in their testbed. The processor was tested in various CPU and GPU benchmarks including – wPrime, CineBench, 3DMark, AIDA64 and X264 FHD. For complete benchmarks, head over to Coolaler.
