Intel Pentium G3258 Processor Review – Overclocking Quest For 5GHz

Intel Pentium G3258 CPU – Budget Overclocker of the Year?

The Intel Pentium G3258 20th Anniversary Edition processor was released to the public this week and Legit Reviews have been waiting for weeks to pick this processor up. Why have we been highly anticipating a low-end Intel Pentium processor? Well, we remember the old days when you could get massive overclocks on inexpensive processors and get some decent performance out of them. The days of using a pencil or rear window defogger kit to get a sick overclock are certainly a thing of the past, but that doesn’t mean that there still aren’t budget friendly processors that can be overclocked to the hilt. When Intel announced that they were coming out with a Pentium Processor Anniversary Edition processor we were excited. The thought of a cheap processor that was unlocked was no longer going to be a thing of a past that old timers reminisce about at LAN parties or to friends. The Intel Pentium G3258 20th Anniversary Edition processor has been released and it will be the budget overclocking champion for the DIY PC enthusiast of this generation!


The Intel Pentium G3258 processor (Intel ARK) is an unlocked Dual-Core, 3.2GHz processor with 3MB of cache. This is a basic 22nm Haswell processor that has entry level Intel HD Graphics (up to 1100MHz) with Intel Quick Sync Video enabled. The bad news is that it is a basic processor. That means it lacks Intel Hyper-Threading, Turbo Boost, Intel Clear Video HD, vPro, VT-d technologies along with the AES and TSX-NI instruction sets.

Intel Pentium G3258 GPU-Z

The key selling point of this specific processor is that it has an unlocked multiplier and it is the only Intel Pentium processor that is currently on the market to be unlocked.


Intel has interestingly priced the Pentium G3258 processor at $72, which is actually less expensive than the Intel Pentium G3440 ($75) and the Pentium G3450 ($86). The all of the Intel Pentium G3XXX series processors share the same dual-core Haswell microarchitecture, Intel HD Graphics at 1100MHz and 3MB of L2 cache. The only real big difference between the processors in this series is their clock speeds. The Intel Pentium G3258 is clocked at 3.2GHz, which is 100-200MHz slower than the G3440 and G3450. Who cares? We won’t spoil the overclocking section, but you should easily be able to get the Intel Pentium G3258 by at least 1GHz and some lucky folks will get 1.5-1.8 GHz overclocks on this processor. Why Intel priced the Pentium G3258 lower than some of the other Pentium SKUs is strange, but it is in the consumers favor and we’ll take the gift. As far as we are concerned the only Intel Pentium processor that one should be buying right now is the unlocked Intel Pentium G3258 as long as it is placed on a board that supports overclocking and is overclocked!
Intel Pentium G3258 Processor Retail Packaging

We were able to purchase two of them up at Micro Center locally when they were on a pre-order special for $59.99 plus tax. This meant that we were out the door for $65 each, which is a great price and below the Intel suggested tray pricing. If the Intel Pentium G3258 can get close to hitting 5GHz like the rumors say that would almost be a steal! Amazon currently has the Pentium G3258 in-stock, but they want $89.99 shipped for it right now. The product code for this retail boxed LGA1150 processor is BX80646G3258.

Intel Pentium G3258 Processor

Here is a look at the Intel Pentium G3258 processor and on the Integrated Heat Spreader (IHS) it shows the model number, S-Spec, Batch number and where it was made. This particular Intel Pentium G3258 CPU has an S-spec of SR1V0, a batch number of 3418B990 and that it was made in Costa Rica.

Intel Pentium G3258 CPU Pins

Flipping the processors over you can see that the Intel Pentium G3258 has the usual capacitors that reside in the middle around the pins needed to operate in an LGA1150 socket.

Intel Pentium G3258 HSF

Intel includes a small CPU cooler or HSF with the Intel Pentium G3258 processor.  The part number is E97378-001 and this particular model uses a Delta Fan (DTC-DAA14). This HSF supports processors up to 95W TDP, so it should handle the 53W TDP Intel Pentium G3258 processor without any issue (unless you overclock it and then you’ll want an aftermarket air or water cooler). Here are the specs the included CPU Cooler:

  • Mfr Part Number: E97378-001
  • CPU Socket Type: LGA 1155/ 1156/ 1150

    Here is nice simple and effective guide to overclock G3258.

  • ferryporsche

    Can the g3258 run the ram at 2133mhz? It would be stepped down to 1333 right?

  • soumen

    man is it x86 or x64? which is it?

  • Wickedpedia PHil

    the G3258 at 3,8ghz will be more than enough for me i just traded my PS3 for a GTX 750 TI i’ll be pairing it with that

  • Shalesh

    65$ cpu with corsair h105 please try to overclock it with stock cooler and share the the result with us i am trying to build a budget gaming pc there isn’t any room for a aftermarket cooler

  • Who the heck is going to pair this cpu with a GTX 780? This cpu is aimed at enthusiasts but also is perfect for budget rigs and a GTX 780 is not a budget video card.

    • Valentin Rafael

      I pair it with GTX 960 and in top popular twitch games runs better than high-end cpus from Intel. Also has upgrade path to i5/i7 if the buyer wants to go streaming or something else that needs more cores.

  • Baumy15

    Could you some testing with the stock cooler and see what you can get?
    I would like to see how far you could overclock it

  • DudeNice

    Why is a $65 budget CPU being compared to $300 powerhouses?

    People who are interested in this processor will be comparing it to i3s, i5s, quad-core FX chips and low-end APUs. Why none of these were included for comparison is beyond me.

    • Nathan Kirsch

      DudeNice – That is what I had tested at the time and I had this 5,000 word review up and done in under 24 hours. Other LR staff members are doing follow-up articles with additional low-end processors, but for now this can give people an idea of what they are looking at in terms of performance both in stock form and when overclocked to 4.8Ghz.

    • Selman Dinç

      hi, this is true . i am wondering i3 vs g3258 @4,5 ghz. this tests not important for me and has no passmark test .

  • Terry Perry

    Why the Low Price because the M.B.’s aren’t selling there is a Huge back up Seriously when did Intel EVER give us a cheap CPU that was a Monster in Speed Never. I remember those so called Good Old days when Intel put out a new M.B. every 6 months because they were all Garbage I went through 12 M.B. in 3 years before I realized it was the O.C. that was killing my M.B. Intel Never told you this.

    • Kreno

      If you’re going to overclock make sure you’re cooling your motherboard’s components otherwise yeah you’re gonna burn out some boards. Research is your friend.

    • faaaaq

      Intel never explicitly said you could kill your mobo by overclocking, and youre mad at them? When you OC, and something breaks, its your fault, not theirs. And unless this was 20 years ago, pretty much every manu warns that OCing can damage things if you dont knwo what youre doing (and clearly you did not)

  • Cicero_68

    Kinda silly to combine a $65 CPU with a $100+ cooler.
    Why not test this CPU in a “budget gaming build with … a decent little CPU cooler”?

    • dood

      This removes any bottlenecks and shows the full potential of the CPU, all good testing is done this way in order to insure that the results are not skewered by bad hardware choices.

      • Nathan Kirsch

        ^^ Plus it keeps the power numbers consistent. Swapping the CPU cooler could change the power draw by a good 3-5 Watts and when dealing with 30 Watt idle temperatures, that is a significant difference. We bought a bunch of these processors (I think 4 and counting) and we’ll be doing more articles with them in the future. Right now Dan is working on a gaming performance article with a bunch of different game titles.

      • Kreno

        Exactly. It would be silly to use a crap cooler with it. You could probably get some pretty close results though with a Hyper 212 Evo though 😉

        Anything beyond about $30 makes a stock i3 a better choice 😛

        • Intranet

          You can overclock to at least 4.0GHz on the crap Intel stock cooler. The cpu is a 65w part – the stock cooler can handle 95w cpus. There are some reviews overclocking to 4.4-4.6GHz on the stock cooler with golden voltage chips.
