Overclocking

Last, but not least, we'll take a look at overclocking. While NVIDIA does support overclocking, they have limited actual overvolting, and instead providing the ability to unlock 1-2 more boost bins and associated voltages. Either way, Maxwell 2 and Pascal certainly have much to thank for high clockspeeds; for Maxwell 2, it was a combination of high efficiency and ample overclocking headroom, while Pascal took advantage of the FinFET process to ramp up the clocks to new heights.

A total of four different overclocks were tested via EVGA's Precision X1; unfortunately, we were not able to get the auto OC scanning functionality to fully work. First was a baseline, consisting of 100% overvoltage and max temperature limits; power limit is already set to a soft cap of 130W at stock. The second was overclocking the GDDR5 memory by 1Gbps. The third was overclocking the GPU by +100MHz; in practice, observed clocks were in the mid 1900MHz. Lastly, all previous adjustments were combined for an overall overclock.

GeForce GTX 1660 Overclocking
  Baseline Memory OC GPU OC All OC
Core Clock 1530MHz 1530MHz 1530MHz 1530MHz
Boost Clock 1785MHz 1785MHz 1885MHz 1885MHz
Memory Clock 8Gbps 9Gbps (+250MHz) 8Gbps 9Gbps (+250MHz)

Naturally, these results cannot be taken as representative of all GTX 1660 cards, but results here can offer some insight.

    Not really sure this works as a 970 replacement. I'll have to peruse Bench to see what the difference between the 960 and 970 were to see if it's worth the money. Might need to wait another generation.... or refresh. Reply

    On which note I've gone ahead and unlocked the GTX 1660 cards in bench.

    The GTX 1660 is a good bit faster than the 970, but it may not be enough to satisfy your needs. Then again, this is a $219 card versus a $329 card.

    Going by current Newegg prices - the GTX 1070 and Vega56 can be had for just under $329 (original 970 pricing) and are both literally 2X faster in many Bench scenarios than the 970. Reply

    Considering the 970 is $100 on ebay right now...

    Roughly 85% of the performance.

    You can justify anything using used pricing. In a freak bit of luck, I got two used 1080Ti GPUs for $400 each last October, virtually eliminating any possible price/performance comparison. Assuming the OP bought the 970 new, it's a fair comparison to look at current $329 cards. Reply

    It's irrelevant what they paid for the 970. They already have it, so it's effective cost on whether to upgrade is what they can get for it when they sell it, or if they don't sell it, $0. Reply

    Of course it's not. He's not talking about going out and buying a 970 today at that price. The real question is if the increase in performance is worth the $150 or so it'll cost him to upgrade (assuming he nets ~$80 by selling the 970 for $100 on eBay. (I'm afraid that price is about to take a hit though.) This is the same question we're all asking ourselves. Original price of our current cards is irrelevant. It's all about current value. Reply

    ^^This.

    Current value is all that really matters. "What is it worth today?" while I'm building my system.

    Tech doesn't hold on to value. $1,000 Extreme Edition CPUs become worthless right about the same time the $200 midrange CPU does typically. The current Core ix going from dual core up to 28 core may throw a kink in that statement, but historically it has held true.

    I'm saying for the money the 970 isn't a bad deal.

    If the price drops more then that deal improves, SLI and go about your day.

    I'm not talking about valid comparisons, apples to apples, none of that, just saying that today if I need a video card a used 970 is very cheap and performs pretty well. If you've already got one then SLI is a cheap upgrade.

    For any of my broke buddies I'm recommending the 970. I'm not sure what I'd recommend new right now, I guess that ultimately comes down to the budget of the build. 2060 is looking pretty good though. It'll be much better in about six months after the price drops (hopefully).

    My R9 280x still maxes or nearly maxes everything I play. Simply for power and thermal upgrades, as well as DX features, I'll probably "upgrade" to a GTX 1660, but that card is so much faster than this one, on less power, and this one already does everythingI need it to so....

    That's the biggest problem I see for GPU manufacturers. Why do I need more GPU when there hasn't been a half decent game released in 10+ years?

    I play Dark Souls 3, Rocket League, KSP and Mordhau. Mordhau is the most demanding but it looks great even at medium. Civilization is a great game, that already runs great. I just installed KOTOR with a ton of mods, that was fun, think it came out in 2003. Wanna do Mass Effect modded out next, what was that, 2008?

    I don't think anyone needs a RTX anything, or anything above the GTX 1660ti. But more power to the people who buy that stuff, keep these guys funded I love their work! I'm just not rich enough to buy stuff without need motivating it. So when every modern game is udder crap, or from an Indie developer who knows how to code so it runs on 10 year old hardware... there's just no need for much more GPU power.
