Both of these are at the new 16nm process, so they run really cool: 67 degrees on air under load. They say these babies will OC past the 2 Ghz point easily.
Along with the cards they are updating their driver and gameworks API giving devs a few new tools. First, fully GPU driven physics, which will probably be very useful, specially in VR applications. There’s also a camera mode built into the drivers API that let’s you have complete control over the game camera, allows you to add filters change to FOV and take screenshots up to 10x 4K resolution.
Finally, the new drivers allow for up to 16 different view points to be rendered in a single pass, allowing multi-monitor setups to be perspective correct on all monitors regardless of angle. Probably more importantly, they boost performance in VR and stereoscopic 3D by 100%.
My 780ti still runs most games well even on my 1440p monitor, but that 1070 is looking mighty tempting at $350. It’s slightly faster than a single 980ti.
Fully GPU-driven physics: Is this retroactive to other Nvidia GPUs?
Are they doing anything more with dynamic lighting or VXGI?
I’m somewhat surprised that the GTX 1070 is getting 8GB of DDR5 rather than 4GB of DDR5X. It seems like once a GPU has 4GB of VRAM, it can make a lot more use out of increased memory bandwidth than memory capacity unless you’re specifically going for 4K.
The 1070’s memory bandwidth is 256GB/s*, that’s about 30% higher than the GTX 970 bandwidth. Unless they’re using even more compression to transfer the load from the memory interconnects to the cores, there may not be as much performance improvement as one might expect from so many tech changes.
I do wonder how much Nvidia will let people overvolt and overclock the 1080’s DDR5X memory though. That could be very interesting. Given that it’s 64 bits rather than 32, if it can be overclocked as hard as my GTX 970’s memory can (8.2Gps), that would give us a memory speed of about 16Gps for a memory bandwidth of 512GB/s.* That* would be a big deal and worth paying 600$ rather than 350$.

They look pretty damn sweet. I think I’m in for a 1070, might even splurge for a 1080 but probably not. Ebay says my current card (770) sells for around $150. If I could get that, that’d be a pretty huge upgrade for $200. Although if I wait until the cards launch, the market will probably get flooded with used cards and the price will go down. But I don’t have a spare card/onboard video to sell it early and wait.
I was wondering what they were going to do with the naming. It’s sort of silly that the people buying the 1080 wouldn’t be gaming at 1080p, so it’s sort of a pleb name. That’s what they get for skipping through their hundred series too fast, skipping generations. Watch retards say “you need a 1080 for 1080p! pc gaming is expensive!”
I’ve been hoping for a pretty big leap this generation, it’s been a while since we’ve had one. Looks like this is it. Interesting that they’re not going with HBM - I guess it’s not ready for mass production yet.
Currently, HBM2 is going to entreprise-grade GPUs. Perhaps the GP100 dies which didn’t cook right but aren’t up to entreprise-grade specs might be resold as workstation GPUs and perhaps flagship gaming GPUs.
Now that I think about it, 2 GTX 1070s will be just 17% more expensive than 1 GTX 1080. That could be really interesting, especially for VR which should have decent scaling.
The few sites I’ve visited to get more details are showing the 1070 at $379-380 as the announced price. Still pretty cheap for a new, leading-edge card.
Looks like the real world benchmarks are in line with what they promised. About a minimum of a 20% improvement over the 980TI, average somewhere around 35%, max around 60%. Lower power draw and heat. Better overclocking. VR-specific hardware enhancements tha should make the gap bigger for VR.
Surprised to see how much of that improved performance simply comes from clock speed though rather than architectural improvements. The clock speeds are 60-70% higher than the previous generation which is a huge jump for just a process jump.
It looks like the memory bandwidth is the limiting factor in a lot of scenarios. They really didn’t improve the memory bandwidth from the high end of the last generation (980TI has a 384 bit bus vs 256) and it feels the limits. Some people are reporting at 1440+ that overclocking the memory has a much more direct scaling effect than upping the core clocks.
Which probably means the 1080TI or whatever comes out with HBM 2 will be a big leap.
There’s another new feature that is possible thanks to the hardware improvements they’ve done to asynchronous workloads and VR’s timewarp. They’re calling it Fast Sync, and it’s basically triple buffered Vsync, but with no latency. The pipeline can wait until the very last few microseconds before sending the frame off to the buffer.
I’m thinking about pulling the trigger on a new GTX 1080 system from Cyberpowerpc. Anything particularly wrong about the build below? Total cost comes to $1627.

If it were my money, I’d wait a bit until the non-reference GPUs become available which should be shortly. They’re looking to be higher performance and a bit cheaper.
If it’s a generic power supply, I’d aim for 750ish. 600 is probably fine (if a high quality unit), but it makes me nervous when they just list a generic unit and I’d want more headroom. Otherwise that’s really good.
I’ll have to look more into hybrids. It looks like a hybrid with the same specs as the SSD/HDD combo I chose would be an extra 75 bucks. I suppose not having to manage where to store things might be nice, as long as it does a good job of figuring out what I really want it to use the SSD for.
I have a 1080p monitor now. I am contemplating getting a 1440p monitor elsewhere but haven’t shopped around for those yet. I’ll probably get some new speakers too.
I can bump up the PSU to 800 watts for 8 bucks so I might as well. The calculator I used recommended 450 watts so I thought 600 would be safe since I don’t plan on overclocking and I don’t usually upgrade piecemeal.
You should still have an SSD for your operating system. Hybrid drives work by learning what you use the most and putting that on their solid state component. This works badly with an OS because it’s liable to keep needing a large number of small files where each of those small files is seldom needed on an individual basis.
600 is generally fine for a single GPU system, and most people overestimate their power needs. However, I’m talking about a high quality power supply. Your prebuilt doesn’t mention a brand or model, just “600w psu”, which makes me worry it’s a cheapie. In which case a 800w cheapie is less likely to end up being unable to handle the load than a 600w cheapie.
500gb SSD and 2TB mechanical drive is fine. If it’s cheap to upgrade the 2TB to a hybrid, do that, but it’s not a big deal. You’ll generally keep slow stuff on the mechanical drive like movies and photos and such, and things that need to be fast like OS and games will go on the ssd.
AMD’s announcement suggests their new Polaris line (480) is going to have 85% of the performance of a 1070 for $200. We don’t have real world benchmarks yet, so their numbers may be playing to their strengths and optimistic. It probably uses DX12/Vulkan Async stuff which AMD has a significant lead in. But AMD isn’t shooting for the high end to compete with the 1080 until late this year. But their current line is looking to be extremely price competitive. If their announcement is realistic, it’ll bring good a very good VR GPU to the mainstream at $200 and should dominate the mainstream price point.
