The Test

Without any Founders Edition, NVIDIA is pushing out the GTX 1660 Ti as a fully custom launch, and while the EVGA GeForce GTX 1660 Ti XC Black has reference clocks, the TDP is set at 130W rather than the reference 120W. To keep testing and analysis as apples-to-apples as possible, as usual we've emulated reference GTX 1660 Ti specifications. While not perfect, this should be reasonably accurate for a virtual reference card as we look at reference-to-reference comparisons.

Test Setup
CPU Intel Core i7-7820X @ 4.3GHz
Motherboard Gigabyte X299 AORUS Gaming 7 (F9g)
PSU Corsair AX860i
Storage OCZ Toshiba RD400 (1TB)
Memory G.Skill TridentZ
DDR4-3200 4 x 8GB (16-18-18-38)
Case NZXT Phantom 630 Windowed Edition
Monitor LG 27UD68P-B
Video Cards EVGA GeForce GTX 1660 Ti XC Black
NVIDIA GeForce GTX 1660 Ti

AMD Radeon RX Vega 64 (Air)
AMD Radeon RX 590
AMD Radeon RX 580
NVIDIA GeForce RTX 2060 Founders Edtion
NVIDIA GeForce GTX 1070 Founders Edition
NVIDIA GeForce GTX 1060 6GB Founders Edition
NVIDIA GeForce GTX 960 (2GB)
Video Drivers NVIDIA Release 418.91
AMD Radeon Software Adrenalin 2019 Edition 19.2.2
OS Windows 10 x64 Pro (1803)
Spectre and Meltdown Patched

Thanks to Corsair, we were able to get a replacement for our AX860i, and so power consumption figures will differ for earlier GPU 2018 Bench data.

In the same vein, for Ashes, GTA V, F1 2018, and Shadow of War, we've updated some of the benchmark automation and data processing steps, so results may vary at the 1080p mark compared to previous GPU 2018 data.

    Never mind, the second page explains this well. (Parallell execution of fp16, fp32 and int32)

    Not only that.
    With Turing you also get mesh shading and a better support for thread switching, which is a awful technique used on GCN to improve its terrible efficiency, having lots of "bubbles" in the pipelines.
    That's the reason you see previous AMD optimized games that didn't run too well with Pascal work much better with Turing, as the high threaded technique (the famous AC which is a bit overused in engines created for the console HW) is not going to constantly stall the SM with useless work as that of frequent task switching.

    “Worse yet, the space used per SM has gotten worse“. not true.. you know, turing have separate cuda cores for int and fp. It means when turing have 1536 cuda cores means 1536 int + 1536 fp cores. So on die size actually turing have 2x cuda cores compare to pascal

    Not exactly, the number of CUDA core are the same, just that a new independent ALU as been added.
    A CUDA core is not only an execution unit, it also registers, memory (cache), buses (memory access) and other special execution units (load/store).
    By adding a new integer ALU you don't automatically get double the capacity as really doubling the number of a complete CUDA core.

    Here are some spelling and grammar corrections.

    This has proven to be one of NVIDIA's bigger advantages over AMD, an continues to allow them to get away with less memory bandwidth than we'd otherwise expect some of their GPUs to need.
    Missing d as in "and":

    so we've only seen a handful of games implement (such as Wolfenstein II) implement it thus far.
    Double implement, 1 befor ()s and 1 after:

    For our games, these results is actually the closest the RX 590 can get to the GTX 1660 Ti,

    This test offers a slew of additional tests - many of which use behind the scenes or in our earlier architectural analysis - but for now we'll stick to simple pixel and texel fillrates.
    Missing "we" (I suspect that the sentence should be reconstructed without the "-"s, but I'm not that good.):

    "Looking at temperatures, there are no big surprises here. EVGA seems to have tuned their card for cooling, and as a result the large, 2.75-slot card reports some of the lowest numbers in our charts, including a 67C under FurMark when the card is capped at the reference spec GTX 1660 Ti's 120W limit."
    I think this could be clarified as their are 2 EVGA cards in the charts and the one at 67C is not explicitly labeled as EVGA.

    Thanks

    The model numbers have become quite confusing
  • Yojimbo - Saturday, February 23, 2019 - link

    I don't think they are confusing, 16 is between 10 and 20, plus the RTX is extra differentiation. In fact if NVIDIA had some cards in the 20 series with RTX capability and some cards in 20 series without RTX capability, even if some were 'GTX' and some were 'RTX', then that would be far more confusing. Putting the non-RTX Turing cards in their own series is a way of avoiding confusion. But if they actually come out with an "1180" as say some rumors floating around, that would be very confusing.

    Interesting to see the next year.
    Rtx 3050 and gtx 2650ti for the weaker version, if we get one new card rtx family... Hmm... that could work if They keep the naming. 2021 RTX3040 and gtx 2640ti...
  • CiccioB - Thursday, February 28, 2019 - link

    Next generation all cards will have enough RT and tensor core enabled.
