1440P overclocked:
GTX 1070 is 3% faster than GTX 980Ti
GTX 1080 is 23% faster than GTX 980Ti

I remember not picking up 980 Ti because it was in many scenarios that 5-20% performance increase. Worst case a few fps, best case a noticeable difference, and of course the DX12 marketing.

examples firestrike http://www.overclock.net/t/1406832/single-gpu-fire-strike-top-30 and firestrike extreme http://www.overclock.net/t/1443196/fire-strike-extreme-top-30
Looking at firestrike scores in the benchmark sections I see to a 20-25%+ improvement on the 980Ti.
Then another 20-25% for 1080 to 980Ti
Last 20-25% for Titan XP to 1080
The extreme scores are is very similar

I'm trying to understand how in this large gap of architectural improvements over 2 generations that a SLI 780 Ti is putting up the scores close to this 1080 Ti. Could it be another 50mhz will make 5-10% out of this card? Something just doesn't seem right with my numbers, maybe the custom 780Ti's are very strong and still capable or the reference 1080 Ti design is really held back with it's power draw?

My best guess is because of 2 reasons:

1. VRAM bandwidth, the GTX 780ti had a much more favourable BW to Flops ratio so it was less bottnecked, granted its not a hard advantage because Pascal has fantastic caching and mem compression but I suspect its still a net loss in ratio (for Pascal). I mean, most OC tests I've seen show measurable to modest improvements to performance via VRAM OC even with GDDR5X so I suspect there still performance on tap if they ever do a HBM2 GP102 card.

2. 2x780ti actually has more cores at fairly competitive clocks. While again, the tile-based rendering of Pascal compensates for the discrepancy via sheer IPC. The combination of IPC + Clockspeed might theoretically, not fully compensate for the discrepancy.

However, these benchmarks are highly optimized for the specific architectures, in the real world tests, you tend to find the GTX 1080ti pulling ahead because the cores are much better utilized in a moderate-poorly optimised scenario, even assuming perfect SLI scaling.

How much power is this baby juicing out of the system ?
I think I might be limited by my PSU.

Does anyone have that chart that shows games that max out 8Gb Vram, 11Gb, 12Gb etc? I remember it just showed examples of a game or two that used a lot of VRAM.

You should be just fine. You may be hitting thermal/power limits but that's because of the card itself, not the psu.

I don't recall that chart but I know Call Of Duty Advanced Warfare and maybe Black Ops 3 if I recall right when I tested them on my old Maxwell Titan X used 10-11GB of Ram, but mostly just caching textures and stuff I think.

just done the shunt mode on the 2 top shunts left the bottom shunt untouched
😎 The card hold 2088 on core and 6000 on memory not a single drop in clock max TDP 80-86 🙏
On evga aio max temp 50 until ek mlc get released

This was on Conrad.de, with membercard + shoop discount.

My power sticks around 115% to 118% but I've seen it hit 120% every now and then.

What boost are these cards getting if you can get the temperature below 50C?

What is the math for thermal throttling​ exactly? I know I lose 12 MHz when my temps go fro. 59C to 60C. Goes from 2050 to 2038.

Waterblock came yesterday! Installed it and Shunt Modded the card:









2088/12312 (+184/+650)

Temps are in the low 30's °C, Custom Loop with 2*480 Radiators, with fans at lowest possible Speeds and Ambient of 18 ° C.
