The GDDR6 performed about as I expected: I was able to max out the memory speed slider at +1500 MHz, which ends up being 15 GT/s. Then I set about seeing how far I could push the GPU core and memory clocks. Temperatures stayed frosty during testing (50C max-this is one cool cucumber), and the fans aren't even that loud at this speed, so the large cooler and triple fans are definitely doing their job. First, I set the voltage to +100 and cranked the power limit to its maximum (120 percent), and just to be on the safe side I set the GPU fans to a steady 80 percent. I'll need to dig a bit deeper over the coming days to see how much headroom really exists, but I took my standard approach to GPU overclocking with MSI Afterburner. It feels like a bit of an intentional limit to keep the GTX 1660 Ti from encroaching on RTX 2060 territory. Memory speed on the other hand seems quite tame, considering all the other GDDR6 RTX cards are running easily at 14 GT/s stock. The earlier Turing GPUs in the GeForce RTX cards have all hit their limits right around 2000MHz, so I wasn't sure how much more I could get. Asus sent a relatively heavily overclocked card, and while the official boost clock is 1890MHz, I saw peak clockspeeds already hitting 2025MHz. Let's talk a bit more about overclocking. So this test will give Nvidia's latest GPU a bit of an advantage over the other 'reference' cards I've tested, but the RX 590, 580, and 570 are all factory overclocked models, and I expect plenty of models will offer nearly the same level of performance as this Asus Strix card, only at a lower price point. It's also possible to set the card at Nvidia's reference clocks, but VBIOS differences likely mean it will still run a bit faster, plus the cooling should help it hit higher boost clocks. Overclocking is possible of course, and it's something I'll look at in more depth over the next week. I had limited time to test for the GTX 1660 Ti launch, unfortunately, so these initial results are at the factory stock clocks. You can change between two performance modes at the flip of a switch, and there's also a "mute" button that will immediately disable all the RGB lighting if you desire. It's honestly overdesigned for a 120W TDP GPU, with an 8-pin PEG connector and a massive cooler, which means lower temperatures and noise levels. You get triple fans, addressable RGB lighting, dual BIOS, and a factory overclock to 1890MHz for the boost clock (1530MHz base clock). It's priced at $329, a stone's throw from the RTX 2060, but it's also the kitchen sink approach. More on that in a moment.Īsus sent its halo card: the ROG Strix GTX 1660 Ti O6G. The GTX 1660 Ti does drop the memory speed down to 12Gbps (compared to 14Gbps on the various RTX cards), which makes me wonder just how much memory overclocking headroom remains. Turing GPUs are manufactured using TSMC's 12nm FinFET process, and so far all of the GPUs use GDDR6 memory. But you do get the rest of the Turing architecture updates, including support for variable rate shading, simultaneous INT and FP operations, rapid FP16 packed math, and improvements in the cache hierarchy. It also brings back the GTX branding, which is probably all for the best as ray-tracing on hardware below the RTX 2060 level doesn't make a lot of sense right now. Instead, Nvidia ends up with a smaller and more affordable GPU. In their place you get… well, actually, you don't get anything. The newest addition to the Turing family ends up being quite the departure from previous models, as the RT and Tensor cores that have been at the heart of the GeForce RTX story are gone.
