Nvidia GeForce GTX 1070 Gets Upgraded to GDDR5X Memory

After whipping up a GeForce GTX 1060 with GDDR5X memory, Nvidia continues its recycling spree with the GeForce GTX 1070. This time around it wasn't Nvidia who broke the news but Zotac, one of the chipmaker's AIB (add-in-board) partners, that spilled the beans.

Although the GeForce GTX 1070 originally employed GDDR5 memory, the GP104 graphics processor is compatible with GDDR5X memory as we've seen on the GeForce GTX 1080 model. This made Nvidia's life a whole lot easier as the chipmaker only needed to swap out the GDDR5 memory for GDDR5X.

The Zotac GeForce GTX 1070 AMP Extreme Core GDDR5X (ZT-P10700Q-10P) is the first known graphics card to feature Nvidia's new GeForce GTX 1070 design. The closest sibling to the GeForce GTX 1070 AMP Extreme Core GDDR5X is the GeForce GTX 1070 AMP Edition.

The GeForce GTX 1070 AMP Extreme Core GDDR5X is almost a mirror image of the GeForce GTX 1070 AMP Edition. Both come with a 1,607 MHz base clock and 1,797 MHz boost clock. They are also equipped with 8GB of memory across a 256-bit memory interface.

The GeForce GTX 1070 AMP Extreme Core GDDR5X's memory is clocked at 2,002 MHz (8,008 MHz effective) just like the GDDR5 memory on the GeForce GTX 1070 AMP Edition. From a performance standpoint, the GDDR5X model offers zero benefits over the GDDR5 model, which is a darn shame considering that GDDR5X chips can clock all the way up to 10,000MHz.

Zotac listed the GeForce GTX 1070 AMP Extreme Core GDDR5X with a 250W TDP (thermal design power), which is 100W higher than a reference GeForce GTX 1070. It's understandable as the graphics card features a hefty factory overclock out-of-the-box. Curiously, the TDP on the GeForce GTX 1070 AMP Extreme Core GDDR5X is still 30W higher than the company's GeForce GTX 1070 AMP Edition model, which runs with the same overclock.

    Does this mean that NVidia still has a boatload of Pascal to unload even at the 1070 level? In reality these upgrades, like the aforementioned 1070 RAM upgrade, and the further reduction/gimping of high-end GPUs for mainstream use seem to support that... AND this move is not really all that much different in concept to how the RX590 came about.

    I'm definitely curious to see how the GDDR5X versions of the 1070 and 1060 perform relative to their identically clocked GDDR5 counterparts.

    It seems, to me, that memory bandwidth is often an issue with graphics cards, thus higher clocks offer diminishing returns.

    EDIT: guh . . . I missed the bit about the RAM not being clocked any higher than the non-X variety. I guess I know one of the first, easy things users of these new cards can overclock, then.

    I think it means two things:
    1. NVidia has excess inventory of Pascal GPUs.
    2. There is either excess inventory of GDDR5X or supply of GDDR5 is constrained.
