Scalable Link Interface, abbreviated as SLI is the brand name of NVIDIA’s multi-GPU technology. The SLI technology is used to combine two or more video cards to produce a single output. You can increase the processing power of your computer by using GPUs that support SLI. So, you can understand that all GPUs don’t support SLI technology.
There are 3 types of SLI configurations including 2-way SLI, 3-way SLI, and 4-way SLI. The GeForce GTX 1070 and 1080 are 2-way SLI cards. In 2-way SLI, 2 GPUs are combined using a 2-way SLI bridge. You know only the 2-way SLI is officially supported by GTX 10 series cards.
GeForce GTX 1070 SLI Vs 1080 SLI -Comparison Between Them
(A) GTX 1070 SLI
1. Key Configuration
Released in June 2016 the GeForce GTX 1070 SLI is still at the top of the priority list of gamers. It is equipped with Pascal architecture offering 1920 Shader Processing Units, 120 TMUs (Texture Mapping Units), and 64 ROPs (Render Output Pipelines).
It can access an 8GB frame buffer of GDDR5 SDRAM through a 256-bit memory interface and the memory clock operates at 2002 MHz. In turbo mode, the core clock speed and the boost clock speed are 1506MHz and 1683 MHz respectively.
It comes with 1 DVI connector, 1 HDMI connector, and 3 display ports. You will also get 1 8-pin connector with it. With a rated board TDP of 150W, the card needs at least a 500W PSU with the available connector.
2. Game Performance Synopsis
This Pascal-based card is designed to meet the requirements of modern games like DirectX 12 games and AAA games. It can provide an excellent frame rate at both 1080p and 1440p displays.
Based on the performance of the 1070 SLI at Ultra graphics settings and the frame rate returned at 1080p, 1440p, and 4K resolutions here is a short performance synopsis for 1070 SLI.
When it is run at 1080p resolution to play Star Citizen it will return an excellent frame rate across the following graphics settings –
Low: 292 FPS
Medium: 230 FPS
High: 155 FPS
Ultra: 111 FPS
When it is run at 1440p resolution (which is the most popular resolution to gamers today) to play Star Citizen it will return an excellent frame rate across the following graphics settings:
Low: 222 FPS
Medium: 175 FPS
High: 118 FPS
Ultra: 84 FPS.
When it is run at 1440p resolution to play Back 4 Blood it will return an excellent frame rate across the following graphics settings:
Low: 236FPS
Medium: 186FPS
High: 125FPS
Ultra: 89FPS
When it is run at 1440p resolution to play Dying Light 2 it will return an excellent frame rate across the following graphics settings:
Low: 148FPS
Medium: 117FPS
High: 78FPS
Ultra: 56FPS
A common question we get from gamers that how long NVIDIA’s GeForce GTX 1070 SLI card will be able to play newly released games.- Well, we predict that it can give you a satisfactory service for 2 to 3 years more.
(B) GTX 1080 SLI
1. Key Configuration
Released in May 2016 the GeForce GTX 1080 SLI is still dominating the market. It is equipped with Pascal architecture offering 5120 Shader Processing Units, 320 TMUs (Texture Mapping Units), and 128 ROPs (Render Output Pipelines).
It can access an 8GB frame buffer of GDDR5X SDRAM through a 256-bit memory interface and the memory clock operates at 1251 MHz. In turbo mode, the core clock speed and the boost clock speed are 1607MHz and 1733 MHz respectively.
It comes with 1 DVI connector, 1 HDMI connector, and 3 display ports. You will also get a pair of 8-pin connectors with it. With a rated board TDP of 360W, the card needs at least a 600W PSU with the available connectors.
2. Game Performance Synopsis
The GTX 1080 SLI meets the DirectX 12 gaming requirements and can run top-tier AAA games at 1080p, 1440p, and even 4K.
Based on the performance of the 1070 SLI at Ultra graphics settings and the frame rate, it returns at the popular display resolutions here is a short performance synopsis.
When it is run at 1080p resolution to play FIFA22 it will return an excellent frame rate across the following graphics settings:
Low: 510 FPS
Medium: 401 FPS
High: 270 FPS
Ultra: 193 FPS.
When it is run at 1440p resolution to play FIFA22 it will return an excellent frame rate across the following graphics settings:
Low: 389 FPS
Medium: 306 FPS
High: 206 FPS
Ultra: 147 FPS
A common question we get from gamers that how long NVIDIA’s GeForce GTX 1080 SLI card will be able to play newly released games.- Well, we predict that it can give you a satisfactory service for more than years from now on.
Final Thoughts
Since the GTX 1070 SLI and 1080, SLI is still good they are surviving in the market otherwise NVIDIA would not invest in these cards. The best-suited resolution for GTX 1070 is 2560×1600. For optimal performance, it is recommended to use Core i7-6700K 4-Core 4.0GHz CPU and 16GB RAM.
On the other hand, the best-suited resolution for GTX 1080 is 3840×2160. For optimal performance, it is recommended to use Core i7-6800K 6-Core 3.4GHz CPU and 16GB RAM.
