Back in those days, overclocking was fun and not something where the mass have to bleed their bank dry. It was the good times when low-cost processors can get a boost of up to 50%, starting the days of overclocking. However, things changed since. We had dual cores, quad cores, Hexa-cores. All of a sudden, chipmakers have introduced series of locked and unlocked processors. The early days of overclocking changed where certain chipsets, motherboard enable you to overclocking. Overclocking was cheap, and the only ‘extra’ add-on you’ll end up purchasing was a CPU air cooler. You never really need to spend a lot to get the best, but you will eventually overclock it to get there.

Now? It’s about who has the big toys, HWBOT rankings, resources, cherry-picked stuff like processors, graphic cards, etc. , special BIOS with certain unlocked that’s left out from public for certain reasons, LN2 pots and all that. But if one wanted more. Not that it’s bad, we still do see innovation. It’s just that now overclocking is now the hobby of the resources and the somewhat rich.

Intel 20th anniversary Pentium G3258 sort of rekindles that spark of the old days or sort of bring nostalgia (but with Haswell architecture) for those older enthusiasts and end-users in the PC master race. This processor was along with the Devil’s Canyon lineups.

Specs-wise, the G3258 is a dual-core piece of cake for LGA 1150 socket with a base clock speed of 3.2GHz with 3MB cache and supports up to 1333MHz dual channel. At the time of launch, it was priced for $72. Nostalgia, anyone?


The unlocked versions are currently available only in certain i5 and i7 ranges. There was a high requirement for unlocked lower-than-i5 series processors because that’s the area where the mass would really need to overclock without really going for fancy spending.

Overclocking is preferred by gamers and enthusiasts. HTPC users, general PC users and even office PC users wouldn’t care or know what’s the point of unlocked processors. Some HTPC users may consider it, some may not. depending on their system at the end of the day.

I benchmarked the 3.2GHz clock speed with 3.7GHz OC along with Gigabyte Z97N-WiFi whose review will also be up soon. I used the stock CPU cooler because of the main point that it’s unlikely that someone who will buy a low-cost unlocked Pentium processor would spend approximately half the amount of the processor for a CPU cooler (unless they happy to have one lying around).
