Intel Pentium G3258 Processor Review – Overclocking Quest For 5GHz

Jump To:

Euler3d CFD Benchmark

Next up is the STARS Euler3d CFD benchmark. The benchmark is intended to provide information about the relative speed of different processor, operating system, and compiler combinations for a multi-threaded, floating point, computationally intensive CFD code. The benchmark testcase is the AGARD 445.6 aeroelastic test wing. The wing uses a NACA 65A004 airfoil section and has a panel aspect ratio of 1.65, a taper ratio of 0.66, and a 45 degree quarter-chord sweep angle. This AGARD wing was tested at the NASA Langley Research Center in the 16-foot Transonic Dynamics Tunnel and is a standard aeroelastic test case used for validation of unsteady, compressible CFD codes.

The benchmark CFD grid contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances the Mach 0.50 AGARD flow solution. The Intel Fortran compiler (ifort 10.0) is used and all floating point variables are Fortran’s double precision (8 bytes). Parallelization is through OpenMP. The benchmark score is reported as a CFD cycle frequency in Hertz and that is what we used to make out chart.

Benchmark Results: The Intel Pentium G3258 in stock form isn’t anything to write home about, but when overclocked the performance is just a hair slower than the Intel Core i7-4790K Devil’s Canyon processor when it comes to single and dual-threaded performance.

    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.

      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 Dinรง

      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 ๐Ÿ˜‰

        Anything beyond about $30 makes a stock i3 a better choice ๐Ÿ˜›

        • 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.
