NVIDIA Next GEN Possible Prototype Leaks – 12GB GDDR6 Memory

NVIDIA’s next-generation GeForce GPUs are in the works and one of the prototypes has found its way to Reddit. It looks like it has a 384-bit memory bus, 12GB VRAM, and three 8-pin power connectors (woof) along with a second generation NVLINK connector.  Estimatesclaim it could result in bandwidth output of 672GBps which is more than any NVIDIA consumer grade card at the moment. To put it into perspective, a Titan V has 652.8GBps while the Tesla V100 is 897GBps. The prototype was posted by a Redditor claiming his “buddy works for a company that is testing NVIDIA boards and this is apparently their new line up”. (We’ll see) Some people claim this prototype is setting us up for 16GB of memory (sweet Jesus)
NVIDIA prepping a new line up of cards to the point where its being tested by outside agencies is an interesting development when you consider that NVIDIA CEO Jen-Hsun Huang announced that the company would not be launching any new GPUs for “a long time”. Crazy when you think about the fact that the GeForce 10 series of cards have been around for two years.  This is leading people to speculate that the lack of next-generation GeForce cards has to do with the company overestimating mining demand.
Cooling fan manufacturer Power Logic has stated it expects shipments to increase in the third quarter. The company makes fans used by global graphics card brands so it probably has an idea of NVIDIA’s roadmap, particularly with the rumored GeForce GTX 1170 and 1180 GPUs.
Power Logic Chairman Hsu Wen-feng talked about the Asian Games 2018 in August as a possible tipping point for greater demand, perhaps hinting at when NVIDIA may just announce its next-generation GPUs in August.  All I’m going to say is when preorders are available, YOU NEED TO JUMP ON BOARD.

Bitmain’s Mining Pool Nearing 51% Control

According  CoinDance, bitcoin mining pools BTC.com and Antpool have mined 25.5 percent and 16.5 percent, respectively, of all bitcoin blocks over the past seven days. Both of these mining pools are owned by Bitmain — the world’s largest producer of application-specific integrated circuit (ASIC) miners.  Meaning that the firm now has influence over at least 42 percent of the Bitcoin hashrate. The two pools also control a combined 21.3 percent of the Bitcoin Cash hashrate, which operates on the same algorithm (SHA-256) as Bitcoin.
Bitmain is dangerously close to controlling 51 percent of the Bitcoin hashrate.  This would theoretically allow it to attempt a 51 percent attack against the network. Such attacks have recently been successfully deployed against a number of smaller altcoins, including Litecoin Cash, Bitcoin Gold, Verge, and Monacoin. There is far less financial incentive to attack Bitcoin, but some in the community nevertheless worry that  CEO Jihan Wu‘s support for bitcoin cash and controversial scaling proposal SegWit2x, that Bitmain might launch a malicious attack against the network anyway. That’s a very unlikely scenario, but critics argue that the fact that it is a discussion at all means that bitcoin mining is becoming too centralized.
The percentage of the hashrate belonging to devices physically-operated by Bitmain is unclear, but that point is that pool operators control the block templates for the entire pool. This means that as long as those devices are pointed at Antpool or BTC.com, Bitmain can decide what transactions the pool will process (and which, if any, it won’t).  In 2014, now-defunct mining pool Ghash briefly crossed the 51 percent threshold but in response to community concern encouraged users to move some of their hashpower to other pools. However, it does not appear that Bitmain intends to take a similar tack. In fact, Antpool recently began a zero-fee promotion that will continue through mid-September in a bid to attract even more miners to its platform. While the pool supports a variety of cryptocurrency mining algorithms, the promotion explicitly lists bitcoin as one of the coins that will be exempt from fees.
