NVIDIA GeForce GTX 1070 Founders Edition Video Card Review

Will The GeForce GTX 1070 ‘Pascal’ Video Card Win The Hearts of Gamers?

Last week we were impressed by how the NVIDIA GeForce GTX 1080 8GB GDDR5X video card performed when we put to the test, but not everyone can afford a $699 video card and we understand that. If you have an 2-5 year old video card you might be getting the itch to upgrade to something more modern that has the performance you want to have while supporting all the new features that NVIDIA has added over the past couple generations. The NVIDIA GeForce GTX 1070 uses the same GP104 ‘Pascal’ GPU build on the 16nm FinFET process that is used on the GeForce GTX 1080, but costs a fair amount less. When the GeForce GTX 1070 becomes available on June 10th, 2016, the Founders Edition of the card runs $449 whereas the MSRP for third party GTX 1070 cards is just $379.

The GeForce GTX 1070 costs less because rather than using 8GB of GDDR5X memory it uses 8GB of GDDR5 memory and NVIDIA essentially disabled a GPC unit. The good news is that the NVIDIA GeForce GTX 1070 still has 1,920 CUDA cores in 15 Stream Multiprocessors, 120 Texture Units and 64 ROPs for a peak texture fill rate of 202 Gigatexels/sec. In comparison, the GeForce GTX 1080 has a fully enabled GP104 GPU with 2,560 CUDA cores in 20 Stream Multiprocessors, 160 Texture Units and 64 ROPs for a a peak texture fill rate of 277.3 Gigatextures/sec. Keep in mind that while the GeForce GTX 1070 has 25% fewer CUDA Cores and Texture Units, the price of the card has been slashed by 36% when compared to the GeForce GTX 1080.

What is nice about the way NVIDIA designed the GP104 GPU is that NVIDIA didn’t disable any memory controller channels or ROPs, so the GTX 1070 has the full 64 ROP backend! On the NVIDIA GeForce GTX 970 most all gamers know about ‘ramgate‘ where NVIDIA disabled an L2 segment and impacted memory performance. NVIDIA isn’t touching the memory subsystem that the L2 segment is part of and instead is just disabling a single GPC block.

When it comes to clock speeds the NVIDIA GeForce GTX 1070 Founders Edition graphics card has a base clock of 1506MHz with a boost clock speed of 1683MHz. GeForce GTX 1080 are clocked at 1607MHz base and 1733MHz boost of the GeForce GTX 1080 Founders Edition video card. NVIDIA says that the power delivery system of the GeForce GTX 1070 Founders Edition wass designed with a low impedance power delivery network, custom voltage regulators and a 4-phase dualFET power supply that is optimized for clean power delivery. NVIDIA internal testing showed that most GeForce GTX 1070 cards are able to overclock exceptionally well and can hit over 1.9GHz!

The GeForce GTX 1070 might be stuck using older GDDR5 technology on a 256-bit wide bus, but the good news is that NVIDIA is shipping this card with the highest memory speed of any GDDR5 GPU in the world. The 8GB of GDDR5 memory on the GeForce GTX 1070 is clocked at 4,006MHz or 8Gbps! This allows the GeForce GTX 1070 to have 256 GB/s of memory bandwidth, which isn’t too far behind (only 20%) the 320 GB/s of memory bandwidth found on the GeForce GTX 1080 that uses the new G5X memory.

With regards to power draw, the GeForce GTX 1070 is a 150W TDP video card, which is 20W less than a GeForce GTX 1080. Due to this the GeForce GTX 1070 doesn’t have the vapor chamber cooler used on the GeForce GTX 1080 and will use a GPU cooler with old school heatpipes.

    Just got 18,300 score on firestrike with a zotac 1070 amp extreme running stock clocks, the card boosts to 2038mhz out of the box gonna push the overclock to the max today but im betting it will be one the best overclocking 1070’s especially since it only hit 54c max in firestrike. The only downside is it wont fit into a lot of cases hell i thought my cm storm stryker was a big case and it was a tight fit up against my hd’s and ssd’s cables. But it been great so far love the way it looks and the lighting and even when im gaming its very silent, cant hear it over my case fans.

  • Wookie Groomer

    Can’t wait to see 1070 sli benchmarks against the same cards, some day.

    • Nathan Kirsch

      Already asked for another for SLI testing… Crossing my fingers.

  • CCKMA

    For Ashes of the Singularity test, did you have async enabled for the DX12 test? Given Nvidia still doesn’t have hardware based async and is relying of software tricks to match the hardware edge AMD has with it’s GCN architecture that’s an important distinction to note and expand on

    • Nathan Kirsch

      I selected ‘high’ image quality settings and ran the test. Using v1.1, which has the GPU or CPU focused benchmark option.

  • Marko Novak

    Thx for Temperature & Noise Testing since that is one single information I still needed to know! Definitely waiting for 0db version or AIO water block…

    • Nathan Kirsch

      EVGA and others will certainly have a water cooled version and EKWB will more than likely have blocks soon.

  • Dmitri

    Yay !!!
    The idea to compare 1070 with older cards is nice.
    I’m using gtx570 (heavily overclocked) and it was mostly doing the job at 1920×1200.
    I was only tempted to upgrade to 900 series since i couldn’t see enough value to upgrade to 670 or 770, but then it was not using smaller process.
    So here we are.
