NVIDIA is shaping up to be the most consistent chipmaker in the industry when it comes to per-generation performance and energy efficiency gains. Over the past three generations, spread across the past four years, the company successfully developed increasingly more energy efficient GPUs, which sees its culmination with the Pascal architecture that powers the GeForce GTX 1080 we are reviewing today.
The GeForce GTX 1080 is based on NVIDIA's "Pascal" architecture. This architecture sees the streaming multiprocessors (SMs), the indivisible subunits of an NVIDIA GPU, get even more dedicated components, which increases their performance. NVIDIA claims to have "meticulously" designed the GPU architecture to be as energy efficient as possible given the silicon fab node and is leveraging the 16 nm FinFET node at TSMC for "Pascal."
The GTX 1080 features more CUDA cores than its predecessor – 2560 vs. 2048. It features even more TMUs (160 vs. 128) and, at 8 GB, double the memory. Memory technology sees a major update with NVIDIA's adoption of the GDDR5X memory standard. The memory is clocked at a staggering 10 GHz effective, which gives the GPU 320 GB/s of memory bandwidth over a 256-bit wide memory interface.

In this review, we're taking a close look at the GIGABYTE GTX 1080 G1 Gaming, the company's premium air-cooled GTX 1080 graphics card. Gigabyte has installed a large dual-slot, triple-fan cooler on the card, which introduces customizable RGB lighting to the company's lineup. Out of the box, the card is overclocked to a base clock of 1696 MHz on the GPU. Memory clock remains at the NVIDIA default of 1251 MHz.
In our launch review of the GeForce GTX 1080, we expressed our fears that NVIDIA's decision to go with two MSRPs for the GeForce GTX 1080 could set a potentially dangerous precedent. The company launched the GTX 1080 at an SKU MSRP of $599; however, it set the MSRP of its own reference-design card at $699 and sold it as the "GTX 1080 Founders Edition." We saw the potential for NVIDIA's board partners to see $699 rather than $599 as the base-line pricing for the GTX 1080 to then accordingly price their custom-design boards.
It is refreshing to see the Gigabyte G1 Gaming retail at $649 right now, which is right in the middle of the MSRP and the Founders Edition's price - still not anywhere close to the MSRP, pricing is better than with the MSI GTX 1080 Gaming X we reviewed yesterday, which goes for $719.
