MSI GeForce GTX 1080 Ti Lightning Z Review

By

Board & Power Supply

MSI uses its own design for this board, and that implementation is much different from what the company did for its GeForce GTX 1080 Ti Lightning X card.

Behind a trio of eight-pin auxiliary power connectors, the board has three chokes to smooth out spikes in the electrical input, along with a shunt.

The GeForce GTX 1080 Ti Lightning Z employs a 7+3-phase power supply with doubling. Thus, each phase is able to distribute the load between two parallel 180°-shifted control circuits. You can see the memory's three phases over there on the PCB's right side.

MSI keeps the back of its card tidy-looking. It's home to the memory's PWM controller and a number of other components.

    20% more performance for 100% more price ?

    no ty .. I can GET 2x SLI GTX 1080 ti for the same price.

    Nice 1080ti, I had an msi 680 Lightning and it was the greatest gpu I ever had, and I had like 20 gpus thought the years.

    After allowing for driver improvements since the review, the final result looks an awful lot like a Titan XP with maybe an extremely mild OC. Or a stock Titan XP in an 18C room rather than a 20C room. For $200 more.

    Well, thats not really the point is it?
    Nobody buys a Lightning card because its affordable, you buy it because its a Lightning card.

    $2K for??? There are several "high-end" Ti's in the $700 range (on air) that run better specs than this overpriced card and run same or better benches.

    What is the purpose of this card, LOL.

    Remember about the line, no bad products, just bad price... well this is the case. The price is just ridiculous.

    I cannot believe you gave an Award to this. So basically any overpriced piece of hardware deserve an award by the same logic.

    Also, you never talk about reliability or engineering flaws. For example, you gave that piece of garbage an award...

    Just take a look at this from a fellow user and me... you guys cannot even point out these simple issues and give feedback about the manufacturers design quality.

    This card does not even match the Asus ROG Poseidon's base clocks nor boost clock.. So basically your paying $2K for the cooler

    why are the charts only stock nvidia stuff and none of the competitions overclocked cards.....why is there a stupid video on all pages i hate it....why is there a stupid email popup every time i visit this site. tomshardware i bid you goodbye i have been with you since the beginning, but all the spam video's and popups...and worst of all comparisons thats useless....bye

    For the most part you can always ignore the seemingly helpful prices that Tom's shows in the big green stickers.

    The price of the card is not $2000.

    Bit-tech did a review of the card and mentioned they bought it for $870.

    https://www.bit-tech.net/reviews/tech/graphics/msi-geforce-gtx-1080-ti-lightning-z-review/1/

    When sites sell out of the cards they remove the price from the page making the overpriced $2000 cards the only ones left to actually advertise, hence the price grabber code pulling $2000 and saying that is the price.


    If you dig deep enough you can find the actual vendor Tom's is talking about, Ecotest with 33 whole reviews over the past year, that sells it for $2000 hoping some one will inadvertently hit purchase.

    I simply cannot imagine something of this weight and width is a good thing to be hanging off your PCI bridge...

    Ill pass thanks. And take just about any other similarly spec'ed 1080ti.
