KONTAK PERKASA FUTURES - Bitcoin might not be worth as much as it was at the beginning of the year, but miners are still operating at a phenomenal rate. A new calculation from Bitcoin analyst Alex de Vries says those mining operations are using a stupendous amount of energy. At current levels, de Vries estimates Bitcoin mining uses at least 2.6GW of power per year, and that number could grow to as much as 7.7GW by the end of the year, an astounding half a percent of the entire world’s electricity consumption. KONTAK PERKASA FUTURES - Anyone can mine Bitcoins by contributing computing power to the network, but mining isn’t as easy as it used to be. When you “mine” Bitcoin, you’re actually verifying transactions on the blockchain, a distributed ledger of Bitcoin activity. Bitcoin is designed in such a way that mining gets more difficult over time, so it was possible to mine the currency with a laptop CPU a few years back. Now, you need high-power ASIC (application-specific integrated circuits) hardware that can run those calculations more efficiently to have any hope of making money. KONTAK PERKASA FUTURES - Because Bitcoin is decentralized, there’s no way to know exactly how much power it uses. The numbers de Vries cites are speculative, based on the economics of Bitcoin and the efficiency of mining hardware. To get these numbers, de Vries started with the knowledge that a new block is completed about every ten minutes, and that awards 12.5 Bitcoins. That’s around $15 million in mining revenues per day at current values. Importantly, more computing power does not mean more Bitcoins. Thus, as new miners join the network, it actually just takes more power to produce the same number of coins. Mining is a question of economics, so that’s how de Vries arrived at his final estimate of Bitcoin power consumption. He made the estimate that the power bill makes up 60 percent of the cost when mining Bitcoins. The analysis also assumes that miners won’t keep hardware running if it doesn’t turn a profit, and electricity costs an average of 5 cents per kWh. That’s how de Vries arrived at the upper bound of 7.7GW. The lower bound of 2.6GW is what you’d get if all mining operations were using highly efficient hardware like the Antminer S9. They aren’t so the real value is probably somewhere in the middle.
This is already a huge amount of energy, but de Vries notes that Bitcoin energy usage could easily spike. If the price stops trending downward, more mining hardware will inevitably come online. If prices get anywhere close to the $20,000 highs of early 2018, we could blow right through the upper bound calculation. Mining rewards are designed to go down over time to limit the number of Bitcoins, so this problem won’t last forever. The next drop will come in 2020 when rewards are cut in half. That should, theoretically, result in a 50 percent drop in energy usage. Source : extremetech.com

PT KONTAK PERKASA FUTURES - Last week, we published our AMD 2nd Gen Ryzen Deep Dive, covering our testing and analysis of the latest generation of processors to come out from AMD. Highlights of the new products included better cache latencies, faster memory support, an increase in IPC, an overall performance gain over the first generation products, new power management methods for turbo frequencies, and very competitive pricing. PT KONTAK PERKASA FUTURES - In our review, we had a change in some of the testing. The big differences in our testing for this review was two-fold: the jump from Windows 10 Pro RS2 to Windows 10 Pro RS3, and the inclusion of the Spectre and Meltdown patches to mitigate the potential security issues. These patches are still being rolled out by motherboard manufacturers, with the latest platforms being first in that queue. For our review, we tested the new processors with the latest OS updates and microcode updates, as well as re-testing the Intel Coffee Lake processors as well. Due to time restrictions, the older Ryzen 1000-series results were used. PT KONTAK PERKASA FUTURES - Due to the tight deadline of our testing and results, we pushed both our CPU and gaming tests live without as much formal analysis as we typically like to do. All the parts were competitive, however it quickly became clear that some of our results were not aligned with those from other media. Initially we were under the impression that this was as a result of the Spectre and Meltdown (or Smeltdown) updates, as we were one of the few media outlets to go back and perform retesting under the new standard. Nonetheless, we decided to take an extensive internal audit of our testing to ensure that our results were accurate and completely reproducible. Or, failing that, understanding why our results differed. No stone was left un-turned: hardware, software, firmware, tweaks, and code. As a result of that process we believe we have found the reason for our testing being so different from the results of others, and interestingly it opened a sizable can of worms we were not expecting. What our testing identified is that the source of the issue is actually down to timers. Windows uses timers for many things, such as synchronization or ensuring linearity, and there are sets of software relating to monitoring and overclocking that require the timer with the most granularity - specifically they often require the High Precision Event Timer (HPET). HPET is very important, especially when it comes to determining if 'one second' of PC time is the equivalent to 'one second' of real-world time - the way that Windows 8 and Windows 10 implements their timing strategy, compared to Windows 7, means that in rare circumstances the system time can be liable to clock shift over time. This is often highly dependent on how the motherboard manufacturer implements certain settings. HPET is a motherboard-level timer that, as the name implies, offers a very high level of timer precision beyond what other PC timers can provide, and can mitigate this issue. This timer has been shipping in PCs for over a decade, and under normal circumstances it should not be anything but a boon to Windows.
However, it sadly appears that reality diverges from theory – sometimes extensively so – and that our CPU benchmarks for the Ryzen 2000-series review were caught in the middle. Instead of being a benefit to testing, what our investigation found is that when HPET is forced as the sole system timer, it can sometimes a hindrance to system performance, particularly gaming performance. Worse, because HPET is implemented differently on different platforms, the actual impact of enabling it isn't even consistent across vendors. Meaning that the effects of using HPET can vary from system to system, as well as the implementation. And that brings us to the state HPET, our Ryzen 2000-series review, and CPU benchmarking in general. As we'll cover in the next few pages, HPET plays a very necessary and often very beneficial role in system timer accuracy; a role important enough that it's not desirable to completely disable HPET – and indeed in many systems this isn't even possible – all the while certain classes of software such as overclocking & monitoring software may even require it. However for a few different reasons it can also be a drain on system performance, and as a result HPET shouldn't always be used. So let's dive into the subject of hardware timers, precision, Smeltdown, and how it all came together to make a perfect storm of volatility for our Ryzen 2000-series review.

KONTAK PERKASA FUTURES - Papa Roach frontman Jacoby Shaddix has spoken about his 2017 vocal cord surgery.
KONTAK PERKASA FUTURES - The band had to pull the plug on three US shows in August last year after Shaddix was forced to undergo an emergency operation. KONTAK PERKASA FUTURES - And in a new interview with Philadelphia radio station 93.3 WMMR, the singer admits he was terrified that his voice wouldn’t recover. He says (via Blabbermouth): “In the recovery process, you don't speak. I didn't speak for two weeks before the surgery, because I tried to get the swelling to go down. “It didn't go down, so I had to get surgery, so it was three more weeks of no speaking – that was intense. “But in the recovery process, you try everything to avoid heartburn. So I cut out coffee, tomatoes — all those things that gave me heartburn. Now it's just a matter of just living more of a disciplined life as far as the food I eat. “I don't drink alcohol, so that's not an issue to me. I'm just taking care of myself.” He describes the process as “terrifying” and adds: “You just don't know if your voice is going to show up again. But luckily, I had one of the best surgeons in the business. She did Steven Tyler's, Adele's and Meghan Trainor's surgery. “I've learned a lot about myself and my emotions, but also a lot about my voice and the importance of being able to live a life to support my career.” Papa Roach will head back out on the road in August, a run of shows that also includes an appearance at the UK’s Reading And Leeds festivals.

PT KONTAK PERKASA FUTURES - JessNoLimit pemain game yang tergabung dalam tim pro player Evos Mobile Legends memberikan tanggapan ketika game Arena of Valor (AOV) masuk cabang olahraga Asian Games yang diselenggarakan di Indonesia. pada 18 Agustus 2018 mendatang. PT KONTAK PERKASA FUTURES - Dalam sebuah wawancara, Pria bernama Justin tersebut mengatakan bahwa, meski pemain Mobile Legends, Jess menyambut positif hal tersebut. "Ini kabar yang positif ya, karena istilahnya kan mobile game kan ya, karena dan itu bisa masuk Asian Games itu jadi naik tingkat istilahnya" kata Jess. Pria yang memenangkan Digital Persona of the Year dari acara Indonesian Choice Awards 2018 di NetTV tersebut menambahkan tidak terlalu mementingkan game apa yang masuk, Ia hanya menekankan bahwa tingkatan game tersebut telah meningkat. "Saya sendiri tidak terlalu mikir ya, itu game apa, tapi istilahnya kalau misalnya game itu sampai masuk Asian Game itu, itu artinya tingkatan gamenya meningkat lagi, satu level baru lagi' tambahnya. Jess kembali menyatakan bahwa Dirinya senang mendengar hal tersebut. Tanggapan Jess ini tentu mengejutkan beberapa warganet, mengngat rivalitas pemain kedua game. Tentu, Jess dianggap bijaksana oleh sebagian pihak. Sebelumnya diberitakan, AOV masuk sebagai Cabang olah raga Exhibisi di Asian game 2018 ke-18 th, Jakarta -Palembang dengan nama ESporst. Esports akan masuk sebagai cabang olahraga di Asian game 2018 juga diberikan setelah Kementerian Pemuda dan Olahraga (Kemenpora) memberikan sambutan dalam turnamen AOV di Jakarta, Sabtu (5/5) Pertandingan Esports di Indonesia selalu didukung oleh Kemenpora, lewat Asosiasi Esports Indonesia (IESPA). Alasannya, AOV jadi masuk Asian game bahwa game tersebut sangat populer di banyak negara di kawasan asia. Memang masih ada juga beberapa game lainnya yang sejenis dan cukup banyak digemari, seperti Mobile legends dan Vainglory. Tapi Arena of Valor dianggap lebih memenuhi kriteria pemilihan dari title Esports di Asian game tersebutd dan saat ini sudah dimainkan di lebih dari 85 negara di seluruh dunia. Hal ini menjadi salah satu pertimbangan bagi Federasi Esports Asia atau AeSF dalam menentukan title game yang akan dipertandingkan di Asian game 2018 nanti. Selain itu, AOV juga dianggap telah memiliki struktur kompetisi yang memadai, mulai dari tingkat amatir hingga tingkat international. Hal itu disampaikan Tommy Kurniawan, salah satu selebritas Tanah Air sekaligus staf khusus bidang keolahragaan, saat menyampaikan pesan dari Menpora Imam Nahrawi. Esports di Asian game tahun 2018 ini masih menjadi ajang exhibisi, dan di Asian game tahun 2022 nanti, akan memperebutkan medali. Kenapa Esports baru menjadi exhibisi di tahun 2018 ini? Karena, itu memang merupakan procedur dari Olimpic Council of Asia atau OCA. Suatu olah raga baru, sebelum dipertandingkan sebagai cabang medali, harus melalui proses exhibisi atau demonstrasi terlebih dahulu. Sebelumnya, Indonesia juga menggelar turnamen Esports besar lainnya, yakni Jakarta Minor. Game yang dipertandingkan di Jakarta Minor adalah Dota 2.
