Press Release: SK Hynix Inc. Introduces Industry’s Fastest 8Gb Graphics DRAM (GDDR6)
Quote
Seoul, April 23, 2017 – SK Hynix Inc. (or ‘the Company’, www.skhynix.com) today introduced the world’s fastest 2Znm 8Gb(Gigabit) GDDR6(Graphics DDR6) DRAM. The product operates with an I/O data rate of 16Gbps(Gigabits per second) per pin, which is the industry’s fastest. With a forthcoming high-end graphics card of 384-bit I/Os, this DRAM processes up to 768GB(Gigabytes) of graphics data per second. SK Hynix has been planning to mass produce the product for a client to release high-end graphics card by early 2018 equipped with high performance GDDR6 DRAMs.
 
GDDR is specialized DRAM for processing an extensive amount of graphics data quickly according to what graphics cards command in PCs, workstations, video players and high performance gaming machines. Especially, GDDR6 is a next generation graphics solution under development of standards at JEDEC, which runs twice as fast as GDDR5 having 10% lower operation voltage. As a result, it is expected to speedily substitute for GDDR5 and GDDR5X. SK Hynix has been collaborating with a core graphics chipset client to timely mass produce the GDDR6 for the upcoming market demands.
 
“With the introduction of this industry’s fastest GDDR6, SK Hynix will actively respond to high quality, high performance graphics memory solutions market” said senior vice president Jonghoon Oh, the Head of DRAM Product Development Division. “The Company would help our clients enhance their performance of high-end graphics cards” he added.
 
GDDR6 is regarded as one of necessary memory solutions in growing industries such as AI(Artificial Intelligence), VR(Virtual Reality), self-driving cars, and high-definition displays over 4K to support their visualization. According to Gartner, average graphics DRAM density in graphics cards is to be 2.2GB this year and 4.1GB in 2021 with CAGR of 17%.

Greek Temple
 
   A basic temple model. Terrain is false perspective. No global illumination. Two sun directions. Ambient occlusion is mostly painted by hand. Bounce lighting is also painted by hand. Completed from a live coding session with the students of UPENN

Converted to GeeXLab
I guess i need to learn how convert WebGL 2.0 properly  :-[

3D-Tech News Around The Web / NVIDIA GameWorks Flow - in DX12
« Last post by Stefan on April 22, 2017, 03:25:07 AM »
NVIDIA Flow is a realtime fluid simulation - in this demo, simulating fire and smoke. The simulation is based on an adaptive sparse voxel grid, allowing the simulation to focus compute and memory resources around regions of interest, and track shifts in the region of interest over time.

With the fire, the combustion process is simulated per voxel, generating elevated temperatures and smoke, which influences the visual appearance and produces buoyancy and expansion effects on the fluid simulation.

An adaptive sparse voxel grid is also used to compute self-shadowing on the smoke, increasing both the realism and visualizing the structure of the smoke. The fluid simulation supports real time collision with objects in the environment, along with fuel emitters than can be modified in real time, making the simulation fully interactive.

Did a clean install of Windows when Creators Update landed on April 11 after figuring out how to do it with no external media.  Problem solved. I think there is at least one of these 2 potential causes:
- My experiment on getting Microsoft Basic Display Adapter to work along with the GPU driver.
To anyone interested. Don't try this, it won't work no matter how hard you try. Windows will just install the GPU driver,  essentially cloning the GPU entry in Device Manager.  Other tools like Aida64 end up listing the GPU 2 times even if you clean the mess from Device Manager. Most likely this confuses GPU Caps Viewer;
- Display Driver Uninstaller
This tool, while many geeks recommend it to clean the GPU drivers it most likely messes with Audio driver, it can also mes with Network and Chipset drivers, probably even Realtek Card Reader, making Windows replace a part, if not all of these drivers with inbox versions.

Epic Games has released a realistic, comprehensive Unreal Engine 4 sample along with accompanying documentation to demonstrate the use of high-quality character shader techniques, similar to those used for characters in Paragon, Epic's MOBA for PC and PS4. 

Read more about this sample and if you missed it about the "uncanny valley"
