Nvidia GeForce GTX 1070 8GB Pascal overall performance overview

more than one weeks in the past, we introduced the world’s quickest computer-oriented GPU in our Nvidia GeForce GTX 1080 Pascal evaluate. Reactions have been mixed, no longer noticeably—any time you address a subject as contentious as pics, half of the target audience walks away impressed, even as the alternative half decries a loss of progress. but there’s no arguing the benchmarks. GeForce GTX 1080 beats GeForce GTX Titan X throughout the board. It beats Radeon R9 Fury X throughout the board. And there’s a good danger the 1080 will go uncontested for a whole lot of 2016 as AMD prepares its Polaris structure for a run on the greater extent-orientated phase.

in which Nvidia seemed to step in it became the decision to fee a further $100 for its reference card, now known as the Founders version. Many Tom’s hardware readers are reluctant to pay greater than MSRP for the industrial layout made famous via its radial fan and windowed shroud, specifically considering the fact that overclocking seems limited via the cooler’s loss of thermal headroom.

put together yourself for the same debate, then, as Nvidia lifts the veil on GeForce GTX 1070 overall performance. The business enterprise tells us the Founders edition card will sell for $449. meanwhile, board partners are readying their personal designs starting at an MSRP of $379. Availability isn’t anticipated until June 10th although, so it remains to be visible if the ones costs maintain or if release-day demand drives them up. Such is the trouble with paper launches.

as a minimum we may be confident that the overall performance of GeForce GTX 1070 gained’t trade. the cardboard we’ve got in our lab represents what you’ll have get admission to to in multiple weeks, and it’s an outstanding piece of hardware.

Pascal, extensive

We pass into greater detail on Nvidia’s Pascal architecture and its features in our Nvidia GeForce GTX 1080 Pascal evaluation. If you haven’t examine that story yet, check it out. there is a lot extra to GP104 than the specs imply!

Meet The GeForce GTX 1070

You’ll note that GeForce GTX 1070 seems almost precisely just like the 1080. certainly, it borrows plenty from its huge brother, each electrically and robotically.

There’s the GP104 GPU, to begin. whereas GeForce GTX 1080 comes equipped with a complete GP104 wearing 20 Steaming Multiprocessors across 4 pix Processing Clusters, 1070 sheds a complete GPC, dropping 5 SMs within the method. That leaves it with 15 SMs, or 1920 CUDA cores (vs. 2560) and 120 texture devices (vs. a hundred and sixty). Nvidia similarly detunes its Pascal-based totally processor by using dialing the GPU’s base frequency to 1506MHz and its targeted GPU boost clock rate to 1683MHz (those are 1607MHz and 1733MHz, respectively, inside the GTX 1080).

Nvidia doesn’t contact the chip’s back-end. you still get 8 32-bit memory controllers with 8 ROPs and 256KB of L2 cache bound to each. In overall, that’s sixty four ROPs and 2MB of L2. however while the GeForce GTX 1080 sports activities 8GB of 10 Gb/s GDDR5X, 1070 receives 8GB of 8 Gb/s GDDR5 from Samsung. memory bandwidth consequently peaks at a pleasing round 256 GB/s, or 14% higher than GeForce GTX 980. The GeForce GTX 980 Ti and Titan X in reality advantage from greater throughput than the 1070 because of their 384-bit interfaces (as do numerous AMD cards with 384- and 512-bit buses). but, Nvidia continues that the improved delta color compression we discussed in our GTX 1080 evaluate yields 20% greater effective bandwidth by reducing bytes fetched.
aside from the model name etched into its shroud, the GeForce GTX 1070 Founders version seems much like the 1080, and that’s desirable. dating lower back to the GTX 690, Nvidia’s commercial design motivated what we assume from a excessive-stop pix card. And although I for my part decide upon the purifier strains of generations past to this new faceted body, it’s more essential that cooling and acoustics are properly-accomplished. We expect board partners to offer configurations with superior thermal ability. but, those models usually exhaust waste warmth back into your chassis. a few lovers are excellent with that and layout their desktops accordingly. but because the proprietor of a small form thing gaming device, I must be more discerning. Nvidia’s radial fan pushes heated air thru aluminum fins and out the I/O bracket.

beneath the shroud, variations between the 1070 and 1080 turn out to be extra apparent. whereas the 1080 employs a vapor chamber answer, 1070 sports an aluminum warmness sink with 3 embedded copper heat pipes. nearly veritably that is a cost-reducing measure related to the 1070’s 150W TDP. A lower-electricity card truely doesn’t need such a beefy cooler, even if it’d certainly help GeForce GTX 1070 conquer some of the thermal limits we saw the 1080 hit.

Down on the PCB level, Nvidia implements a four-phase dual-FET layout instead of the 1080’s five-phase power supply. test out the 1070’s naked PCB above, and the 1080’s below for assessment.

The GTX 1070’s I/O bracket includes the equal 3 e4028a5c6dae3ad5086501ec6f3534d0 DisplayPort 1.three/1.four-geared up outputs as 1080, together with one HDMI 2.0b connector and a dual-link DVI port. Up pinnacle, you’ll once more locate SLI interfaces that accommodate Nvidia’s new excessive-bandwidth bridges. not anything adjustments in regards to SLI support: GPUs are nevertheless the max, despite the fact that the organisation will possibly deliver 1070 proprietors get right of entry to to the equal free up key to be had to all of us with a 1080, permitting 3- and 4-manner setups as nicely. And GeForce GTX 1070 similarly sports activities a single 8-pin connector to complement energy brought throughout the 16-lane PCIe slot.
