Discrete GPU Gaming

When comparing CPUs to APUs, one strength shown by team Blue in the past is the discrete GPU performance. When using dual graphics cards at a 1920x1080p resolution, at a lower amount of CPU power overall, there tends to be a significant amount of variance when extra CPU performance is applied. While it seems the overclock numbers are nice for a Pentium, a little extra money for an i3 at stock seems to be the choice here.

All of our titles, except Tomb Raider, get a significant increase from overclocking the CPU.  However, it is worth noting (especially in titles such as Battlefield) that using and i3 from the start gets an even better result. 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.

    It would be interesting to see how a hypothetical i3-K would perform. Perhaps it's possible to test with an i7-K at around 4.5 GHz and two cores disabled?

    Also, it'd be interesting to see benchmarks with the type of games mentioned in the beginning of the review (and a low-mid range GPU) - DOTA 2, League of Legends, Counter-Strike: Global Offensive, popular MMORPGs, Minecraft, etc.

    Yes, I agree totally. I think that the i3-K would the modern day version of the old Celerons because of the fact it is 4 threads. Ian did a great job in this article to show that we are past the point of '2 threads is enough' and a maxed out dual core isn't giving you the same extra free performance like over clocking did in the old days (because of todays low end of 4 thread processors). But as far as gaming is concerned, we have been to that point of '4 threads is enough' as seen by the i5 being the sweet spot for gaming for a couple years now. So a highly overclocked i3-K does fit into that scenario nicely. Perhaps Intel already knows this, and perhaps it fits a little TOO nicely that it would cut too far into i5 sales, and this is the reason they have not made one? So instead they chose to put out the Pentium-AE fully knowing it wouldn't cut into their i3 sales because the performance isn't there.

    Also, I second the request for a hypothetical i3-K test that yhselp proposed!

    Indeed, but remember that we're talking about a specific set of games that aren't very demanding to begin with; in my mind, this Pentium-K or even a hypothetical i3-K would never be enough for proper high image quality gaming with the latest games, however, it might be very well-suited for DOTA/LoL/CS, etc. The source engine, especially with Valve games, is terribly single-threaded so I wouldn't be surprised if an OC'd G3258 actually pulls ahead of stock i3 under certain circumstances with these games. Unfortunately, that's one set of benchmarks we didn't get.

    The problem with using the i-7's and down clocking to simulate lower tier processors is that the L3 cache is still there at 8MB, where those lower tier processors are severely castrated in that department. You can get the memory simulated and thread counts can kind of be controlled.

    Just makes no sense. Overclocking is generally targeted at gamers and data crunchers. The Pentium AE does neither because it has no hyper threading and no AES. Even at 5GHz this thing couldn't touch a stock i3 in gaming or data crunching. The salt on the wound is the i3 can be had for $40 more, and you can SAVE $40 opting for a non-overclocking motherboard chipset.

    So basically for the same price, you can get an i3 platform with superior performance. This thing is literally just for "fun" but once reality sets in and you consider the facts, fun turns to regret.

    I feel as if this chip is simply a delivery platform for high-end Intel chipsets to people who would otherwise get an H-series.

    If you want a real overclocking platform, just spend the extra $100 and get an i5-4690k. If you want a quality gaming CPU or need modern multithreaded performance (and practically all apps/games are multithreaded now, BF4 practically requires quadcore) get an i3 for $40 more and save $40 on the fancy motherboard, breaking even compared to a Pentium AE.

    Typical Intel gimmicks and some its seems think they are doing us a favor or whatever.

    I was actually quite interested with and tinkering with a Pentium K until it was clear Intel makes you by a stinking Z board. Yeah Intel, a real Pentium celebration, for you.
  • Computer Bottleneck - Monday, July 14, 2014 - link

    You don't need a Z board to overclock Pentium G3258.

    Also Intel supplies a beefy 95 watt cooler with Pentium G3258.....so no need buy aftermarket HSF unless a person is trying to squeeze out the last 200 Mhz of the overclock.
  • Samus - Monday, July 14, 2014 - link

    Since only Z boards are firmware-ready for the G3258, unless you have a first-gen Haswell lying around along with a 80-series "new stepping" H81 or better, your stuck with a Z97 or "compatible" H97 (again, read firmware update required.)

    All the launch boards/combo's for G3258 aren't Z97-chipsets by mistake. It is essentially required at this point. It will change as time goes on, but that doesn't change the fact you are better off with an i3+H81 for the SAME PRICE as a G3258+Z97. The G3258 is such a weak multithreaded performer (having two physical cores with no hyper-threading) that if you are looking to spend that little on some fun, you're actually just better off with an AMD platform.

    And the cooler is still shit. Nobody has had their G3258 run for 24 hours at STOCK speed without throttling. STOCK. How do you think 1" of tiny fins and a 1200RPM fan is going to dissipate 50w of heat? Notebook heatpipes are more effective and they only need to dissipate 15-35w of heat.

    Anybody who actually buys this platform is misinformed. The writing is on the wall. No reviewers can morally recommend this chip unless you just like the "fun" of overclocking. Beyond that, its a bad investment. An i3 platform with a more basic chipset will be faster for the same price, or less.

    Why don't you like the stock 3258 cooler? It is the same cooler that cools a Haswell i7 quad core, yet the 3258 even when OC consumes only a modest amount of extra power (see system power consumption chart on page 1 of this review).

    "And the cooler is still shit. Nobody has had their G3258 run for 24 hours at STOCK speed without throttling. STOCK."

    I see plenty of reports in the forums of people using the STOCK cooler that came with the G3258 to hit 4.5GHz running 100% load in the 60-70°C temperature range, without being super noisy either. These are first-hand reports from those who have actually tried it.

    Here is one such thread:

    Also, cheap non-Z motherboards can overclock this CPU:

    (Thanks Computer Bottleneck for the links)

    But you go believe what you want, and if you have proof please post links. Potentially there is a huge conspiracy with a bunch of people posting that the stock cooler works fine when it really doesn't. I do not discount that possibility, however unlikely.
