A complete review of NVIDIA’s upcoming GeForce GTX 780M has been posted on a Chinese forum. Due to company’s NDA policy it was later removed but VideoCardz got hold of the screenshots and results just in time. The review was conducted using MSI GT700 notebook with 4th generation Intel Core i7 Haswell processor, 3 x 128 GB SSDs in RAID 0 and 16 GB DDR3 memory.
First of all, I would like to point out the RAID 0 with three SSDs in a notebook. Perhaps this is the first time I am seeing three SSDs RAID configuration in a notebook, it might be possible that the reviewer altered it himself. According to the GPU-Z screenshot, GTX 780M features 4 GB GDDR5 memory with a 256-bit memory interface. It is equipped with 1536 CUDA Cores, 32 ROPs and 160 GB/s memory bandwidth.
The GPU is clocked at 771 MHz and 797 MHz Boost clock while the memory is clocked at 5000 MHz effectively. GTX 780M is based on GK104 silicon and will replace current GTX 600 series flagship mobile GPU, GTX 680M. The unique feature in the GPU is the support for GPU Boost 2.0 which was first introduced in GTX TITAN. This means that upcoming Desktop GTX 700 series will take advantage of the the same feature as well.
Moving on to the benchmarks, GTX 780M scores P7644 in 3D Mark 11 which is approximately 30% faster than GTX 680M. The 3D Mark Vantage Entry preset score turned out to be 87,780 making it 42% better than its predecessor. The table below shows the comparison of GTX 780M and GTX 680M in various DirectX 11 games. Overall performance difference turns out to be 31% between the two GPUs.
