Individual results will vary from that a bit, but it's a reasonable baseline estimate. Combined, performance in games with the overclocked GPU is about 10 percent faster than at stock. Meanwhile on the GPU clock, I was only able to add 125MHz, which resulted in stable clockspeeds of 1950-2010MHz in games, a 5-6 percent improvement. (I was able to go from 12GT/s to 15GT/s on the Asus 1660 Ti, and 14.7GT/s on an EVGA 1660 Ti.) With the Zotac GTX 1660, I was able to push the GDDR5 from 8GT/s to 9.4GT/s (+700MHz), a 17.5 percent increase. The GTX 1660 uses GDDR5 memory, so it's not going to come anywhere near matching a 1660 Ti.
Then I looped the 3DMark Time Spy stress test while I tweaked the VRAM and core clocks.
System power draw is only 250W, but at least half of that comes from the motherboard, CPU, RAM, and other components-and that's not accounting for PSU inefficiency, which would be actual power draw at 225W, so the GTX 1660 is likely running well under its 120W TDP rating.įor overclocking, I set the core voltage slider to +100 in MSI Afterburner, increased the power limit to 111 percent, and increased the fan speed to 75 percent. During testing, at stock clocks the GTX 1660 runs at speeds of 1845-1905MHz, with temperatures of up to 67C. The boost clock is nominally 1785MHz, but Nvidia's GPUs for the past several generations have rarely run at clocks below that level, often far exceeding the boost clock in games (though not necessarily in GPU compute workloads). Since this particular card doesn't come with any fancy extras, it's also a good candidate to show how much overclocking headroom exists for enthusiasts GPU. This is a no-frills card that provides everything you need, at Nvidia's base $219 price. That's fine with me, though, since anyone looking for such features would usually be better off spending more money and grabbing a GTX 1660 Ti or RTX 2060. There are no RGB LEDs, or any lights for that matter, no dual VBIOS chips, or really any other higher end features. If you have an older monitor that requires a DVI-D connection, you'll have to bring your own adapter to the party.
#1660 GRAPHICS CARD PLUS#
(That's per Nvidia's specs, incidentally, probably to err on the side of caution: a single 6-pin PEG connector plus an x16 PCIe slot should provide up to 120W, but by using an 8-pin connection Nvidia can ensure cards don't exceed the PCIe slot's power capacity.)įor video outputs, Zotac provides one HDMI 2.0b port along with three DisplayPort 1.4 ports, and it can run all four outputs simultaneously. Like nearly all modern graphics cards, it's a dual-slot design, and while it's technically not required, the card uses a single 8-pin PEG power connector. Despite the two fans, it's basically a mini-sized card that can easily fit in smaller cases, measuring just 173mm (6.83 inches) in length. The Zotac Gaming GTX 1660 is nothing fancy, though it does have dual fans for cooling. Nvidia should see much bigger gains when it eventually moves to TSMC's 7nm node, but we'll have to wait a while before that happens. I've said it before, but TSMC's 12nm in practice doesn't appear to be much more than a refinement of its 16nm tech-what Intel would have called 16nm+.
Transistor counts increased from 4.4 billion to 6.6 billion, and die size also went up from 200mm^2 to 284mm^2. Perhaps more interesting is when you look at the GPU and compare it with the GP106 used in the GTX 1060. The GPU at the heart of the GTX 1660 is the same TU116 as in the 1660 Ti, only with two of the SMs disabled, which in turn disables 128 CUDA cores and 8 texture units. If you're using such a card, the 1660 is a great upgrade, while anyone with a GTX 970 or better will probably want to wait a bit longer (or go with a faster and more expensive GPU like the GeForce RTX 2060). That's why I generally recommend trying to skip a generation or two of hardware between upgrades, especially for budget and mainstream gamers, which means the GTX 1660 is better positioned as a replacement for an old GTX 960 or earlier GPU. The GTX 1660 will be faster than the GTX 1060 6GB-it has some architectural enhancements, higher clockspeeds, and more shader cores-but it's not going to be a massive upgrade. Getting more performance at a lower price is great, but with graphics cards there's always a problem of competing with the previous generation.
