However, ramped-up security measures, including federal troop deployments to assist police, have been left in place.,What Happened?,Sierra Leone is one of the poorest nations in the world, ranking 186 out of 198 in a recent GDP purchasing power parity ranking. An estimated 80 percent of the population lives in poverty, many of them in the country’s rural areas. Like other nations in Africa, the country has faced special difficulties amid the global economic calamity brought on by COVID, and exacerbated by Western restrictions on Russian exports of agricultural goods and fertilizers amid the security crisis in Ukraine, which has caused a major jump in food prices.,AfricaAnti-Russia Sanctions Left Africa Without Access to Grain and Fertilisers, African Union Chief Says3 June, 11:13 GMT,As a net importer of both energy and food, Sierra Leone is especially vulnerable to global economic conditions, and along with food and fertilizers, fuel and electricity costs have also soared. Food prices alone have jumped by over 40 percent over the past few months, with a bag of rice once costing 350 leones now going for over 500. The country’s Central Bank recently removed three zeros from the national currency in a bid to restore confidence. The country has also been overcome by weeks of strikes by government workers, including doctors and teachers, and by small traders protesting poor conditions.,Coup Plot?,However, President Julius Maada Bio has also accused protesters of having ulterior motives beyond the cost of living crisis.,“This was not a protest against the high cost of living occasioned by the ongoing global economic crisis. The chant of the insurrectionists was for a violent overthrow of the democratically-elected government,” Bio said in an address on August 12 after returning to the country from a holiday in London.,Local media pointed to the chants of “Bio must go” among protesters as they gathered in the capital, and the president accused some of the demonstrators of consisting of “APC Warriors,” a reference to the opposition All People’s Congress party, which governed the country from 2007 until 2018, when Bio’s Sierra Leone People’s Party won national elections.,No doubt mindful of the violent civil war which shook the country between 1991 and 2002, claiming as many as 70,000 lives and displacing over 2.5 million people, Bio vowed that “in the coming weeks and months, [the] government will undertake necessary security actions meant to guarantee the peace and security of all citizens.”,“The security forces will, and must, act with great restraint and within their professional codes of service. But be assured that my government will crack down hard on violent insurrectionists, their collaborators, their sponsors and their supporters. My government will relentlessly fight those who would rather use terror and gruesome violence to achieve political goals,” the president said.,As a government, we will continue our engagement with Civil Society as we strive to promote sustainable peace, national cohesion and socio-economic development in Sierra Leone. #newdirectionagenda— President Julius Maada Bio (@PresidentBio) August 18, 2022,Bio did not elaborate on who these “sponsors” and “supporters” were, or whether they included any foreign actors.,Geopolitical Context,Like other African nations, Sierra Leone recently rejected calls by Washington and Brussels to show solidarity with the West and Ukraine and impose sanctions on Russia. But even before the escalation of the Ukraine crisis, relations between Freetown and Washington were tense at times. Last year, US President Joe Biden snubbed Bio by refusing to invite the African leader to the US’ so-called “Democracy Summit.” No reasons were given. However, neighboring Liberia, which faced mass civil unrest of its own between 2019 and 2020, and whose officials have been sanctioned by the US over suspected corruption, did get an invite.,While Sierra Leone maintains economic and political ties with its former British colonial masters, and remains a member of the Commonwealth of Nations, Freetown has sought to expand its partnerships with other geopolitical power centers, including Russia and China. President Bio attended the Russia-Africa Summit in Sochi in 2019, where he discussed ways to strengthen economic cooperation between the distant nations. In February 2021, Freetown signed onto Moscow’s efforts to prevent the deployment of weapons in outer space. In May 2021, Bio spoke by phone to President Xi Jinping of China, where they discussed the friendly, “brotherly” relations between the two nations, as well Chinese assistance to Freetown in measures against COVID, and agricultural and economic development.,In this context, the reactions of major foreign powers to this month’s unrest have been telling. While the United States, Britain, and the European Union collectively expressed “grave concern” over the “disturbing reports of violence” and urged the parties to “stay calm, promote accountability and ensure respect for human rights,” China’s Embassy smoothed over the protests altogether, refraining from wagging its finger at Freetown and instead trumpeting the expanding cooperation between the two countries.,We are gravely concerned by reports of violence surrounding today’s demonstrations in Sierra Leone. We urge all parties to stay calm, promote accountability, and ensure respect for human rights and fundamental freedoms.— Bureau of African Affairs (@AsstSecStateAF) August 10, 2022,Similarly, while UK High Commissioner to Sierra Leone Lisa Chesney lectured President Bio about how “violence has no place in a democracy and the necessary investigation into August 10 can sit alongside de-escalation,” the Russian Embassy in the Republic of Guinea, which concurrently serves as the Embassy in Sierra Leone, only presented a bare bones report on the situation in the country, Bio’s meetings with community and tribal leaders, and indicated that an internal “debriefing” was being created “regarding the causes, course and consequences of the riots on August 10.”。          具体来看，玄戒O3首发发16核G2-Ultra NX图形处理器，支持第三代光线追踪，整体算力达到36TOPS。

二 |          性能方面相比上一代玄戒O1提升85%，Aztec Ruins 1440P跑分213分，是A19 Pro的2.2倍；Steel Nomad Light 4657分，领先A19 Pro约55%；Solar Bay Extreme 3628分，比玄戒O1暴涨182%，能效同时大幅改善，同性能下功耗降低64%。

三 |               在AI渲染方面，传统手机的AI图形增强方案渲染数据必须离开GPU，经过SLC或DDR内存搬运到NPU，NPU处理完再搬回GPU继续渲染。一来一回两次数据搬运，延迟和功耗都浪费在数据传输上。         玄戒O3的做法是把NX神经网络加速器塞进GPU渲染管线内部，数据从几何处理、光栅化、着色到NX推理、后处理，全流程在GPU子系统内闭环完成，不需要任何数据搬运。

四 |          硬件原生AI超分下，540P分辨率经2倍超分后画质媲美原生1080P，单帧游戏功耗降低20%，在3.2K分辨率下，两款开放世界游戏30分钟实测平均帧率分别达到119.7fps和119.1fps，基本贴满120帧上限。这意味着玄戒O3不需要靠降低分辨率来换取帧率，高画质和高帧率可以同时兼顾。
