Overview
GeForce GTX 970 4GB SLI is a solution of two GeForce GTX 970 4GB put together using NVIDIA's SLI technology.

Architecture
The Second variant of the Maxwell Architecture, despite being also manufactured with a 28nm technology, has an extremely large L2 Cache and features a Third Generation Delta Color Compression which allows NVIDIA to produce Graphics Cards with relatively small memory data transfer rates, without causing too much impact on the overall performance. Furthermore, the Shaders have been redesigned and are both more powerful and energy efficient.

GPU
It consists of 2 GPUs codenamed GM204-400-A1 which, together, offer 3328 Shader Processing Units, 208 TMUs and 128 ROPs, on a 512-bit memory interface of fast GDDR5. The central unit runs at 1050MHz and goes up to 1178MHz, in Turbo Mode, while the memory clock operates at 1753MHz.

Power Consumption
Power Consumption lies between 300W and 400W.

Performance
Gaming benchmarks prove that at 4K (3840x2160) GeForce GTX 970 4GB SLI is over 25% faster than Radeon HD 7990 and almost as fast as AMD's Radeon R9 295X2.

System Suggestions
We recommend a very strong processor (Intel Core i7 Six Core/AMD FX Eight Core) and 16GB of RAM for a system with GeForce GTX 970 4GB SLI.
