Nvidia’s Pascal GPU GP104 Features Smaller Die, Liquid Cooling – Faster than Titan X
Nvidia’s first high-end Pascal GPU, allegedly called the GP104, has finally been spotted in a shipping manifest on Zauba.
The source website Beyond3D claims to have an inside information on the GPU, according to which the GP104 chip comes in a 37.5×37.5mm BGA package, and has 2152 pins. For comparison, the predecessor GM204 is 40×40mm, and has less pins – around 1745. Which indicates that the new Pascal chip is not only smaller in size, but features a much denser architecture making the chip theoretically faster than both GTX 980 Ti and TITAN X.
Based on the ratio derived from the difference in dimensions, the GP104 should have a die size of around 300 to 350 mm² as compared to the GM204’s 398 mm². We already know that the Pascal GPUs will be based on 16nm FinFET processing node which is approximately twice at dense with a performance jump of 2x, claims the Taiwanese chip maker.
While Nvidia intends to utilize HBM2 memory in Pascal graphic cards, the source claims that the GP104 chip could actually utilize GDDR5X instead, a next-gen verion of GDDR5. This is in line with a previous report which suggests that Nvidia will adopt both architectures: GDDR5X for mid-high tier Pascal GPUs and HBM2 for enthusiast class Pascal ones such as the GP100 aka the Big Pascal.
Last but not least, the shipping manifests suggest that the GP104 graphics card could be powered by a completely new liquid cooled solution – indicating Nvidia’s plans for adopting it as a stock feature on its future GPUs.
