GTX 1080 FE vs GTX 1080 Ti FE - mdelatorre - 08-24-2017
I will like to hear your advice regarding the cost/benefit relation between the GTX 1080 FE vs GTX 1080 Ti Founders edition. Which one would you buy for a cracking rig?
The GTX 1080 FE has a street price of $750 :
- Base Clock: 1607 MHZ
- Boost Clock: 1733 MHz
- Memory Clock: 10010 MHz Effective
- CUDA Cores: 2560
- Memory Detail: 8192MB GDDR5X
- Memory Bit Width: 256 Bit
- Memory Speed: 0.2ns
- Memory Bandwidth: 320 GB/s
The GTX 1080 Ti FE has a street price of $1,300 :
- Base Clock: 1480 MHZ
- Boost Clock: 1582 MHz
- Memory Clock: 11016 MHz Effective
- CUDA Cores: 3584
- Memory Detail: 11264MB GDDR5X
- Memory Bit Width: 352 Bit
- Memory Speed: 0.18ns
- Memory Bandwidth: 484.4 GB/s

1080FE : 2560 * 1733 = 4436480 / $750 = 5915 perf / dollar
1080ti: 3584 * 1582 = 5669888 / $1300 = 4361 perf / dollar
Assuming same architecture and just core and clock differences the 1080 gives you better bang for buck. Haven't factored in power consumption differences.

You should also consider the sizing of your installation. Distributing among several nodes is non-trivial and sometimes package density, performance per enclosure and thermal limits could also favor either the Ti or the 1080.

You need to take total system cost into consideration, not just the cost of the cards themselves.

Thanks Blazer for your answer. Does the product of boost clock by CUDA cores have any physical meaning?
Jeremi (@epixoip) has great benchmarks at his github site so I can calculate hashes/$. For simplification will only do it for NTLM.
1080FE: 41354.8 MH/s / $750 = 55.14 MH/s per dollar
1080tiFE: 53173.6 MH/s / $1300 = 40.90 MH/s per dollar
Today, the 1080FE has better performance and speed per dollar.

Jeremy. I don't understand why I need to take the total system cost into consideration if the only components that will change are the GPU. Everything else will remain constant.

It is possible you may need better PSUs to power 4x 1080TIs vs 4x 1080FE, since they take more power they will generally dissipate more heat thus you may need better fans to cool etc.

Blazer. I haven't think 🤔 in your answer but you are right. In my case I am planning to use as chassis a
Supermicro SYS-7048GR-TR. Thank you for your time and help.
Meme.

Here's with updated prices:
1080FE: 41354.8 MH/s / €509 = 81.24 MH/s per €
1080tiFE: 53173.6 MH/s / €698 = 76.17 MH/s per €
