In unison, these and many other advancements and enhancements make the GeForce GTX 1080’s Pascal architecture the most efficient GPU design ever built.
GeForce GTX 1080's Memory Compression Engine Compared to the GeForce GTX 980’s In the images below you can see a Project CARS scene on the left, the same scene when compressed on previous-generation NVIDIA GeForce GTX Maxwell GPUs in the middle, and on the right the same scene again when compressed with the new Pascal Memory Compression Engine.
This brand new, never before-used G5X VRAM runs at a blistering data rate of 10Gbps, which when combined with the 256-bit memory interface provides 43% more memory bandwidth than on the previous-generation GeForce GTX 980.īolstering this unprecedented level of bandwidth is the new, fourth-generation Pascal Memory Compression Engine, which is able to compress components of a scene to significantly reduce the number of bytes that have to be fetched from memory per frame. Surrounding the GeForce GTX 1080’s 16nm GPU is 8GB of GDDR5X (G5X) video memory (VRAM). At its core is the GP104 GPU, built using a new 16nm FinFET manufacturing process that enables the addition of more transistors, which in turn allows us to crank up the clock speed, whilst simultaneously improving power efficiency. Based on the new NVIDIA Pascal architecture, the GeForce GTX 1080 is the world’s most advanced graphics card.
