Nvidia Pascal GP104 GPU Features 8GB GDDR5 Memory, Die Measures Around 300mm2
Just yesterday, we reported that Nvidia could launch their consumer grade GeForce graphics cards at Computex 2016 in June. The new cards include the GeForce GTX 1070 and GTX 1080, which will both feature Nvidia’s next gen Pascal GP104 GPU that is expected to power a range of graphics chips.
Now, a new close up picture of Nvidia Pascal GP104 GPU has just leaked on the web. According to the leaker, the area of the die measures around 300mm2. This puts the GPU around 100mm2 smaller than the GM204 GPU which measures 398mm2 and features 5.20 Billion transistors.
Still, the die size seems large enough to fit four graphics processing clusters, especially since GP104 won’t need as many memory controllers as the GP100. Assuming the GPU has the same density of FP32 CUDA cores as Big Pascal, we can expect it to feature 2560 CUDA cores in total, as well as 8 billion transistors which is the same count as featured on the current flagship, the GM200 GPU.
Equally interesting is that the board features 20nm GDDR5 K4G80325FB-HC25 memory from Samsung. These latest memory modules use the 8GB DRAM and rated at 2GHz, so this could make up for some of the bandwidth against GDDR5X and HBM2 which we know won’t be available for a while.
Finally, the next gen Nvidia Pascal architecture is built on 16nm FinFET process technology which will enable much reduced power consumption, as well as 2x performance per watt improvement over Maxwell. The Pascal cards are rumored to cost between $600 to $1,100, and as mentioned in the start, could launch at Computex 2016 which runs from May 31 to June 4 in Taipei, Taiwan.
