As military strikes and diplomatic negotiations have both failed to bring an early end to the roughly six‑month‑old US-Iran conflict, Washington rolled out new sanctions against Tehran on Monday local time intended to further strangle its economy. Iran, for its part, has vowed a tougher pushback.
In a news conference on Monday, Treasury Secretary Scott Bessent threatened new sanctions on countries refusing to cut economic ties with Iran, following recent rhetoric from Washington threatening an "economic D-Day" for Iran. 
Meanwhile, the Office of Foreign Assets Control (OFAC) under the US Treasury announced secondary sanctions on nearly 60 entities, individuals, and vessels in multiple jurisdictions which, according to the US' claims, enable Iran's activities, including so-called nuclear and missile technology procurement, cyber operations, and oil-revenue generation networks.
According to Reuters, those sanctions targeted businesses in China, the UAE, Singapore and several other countries, including a cooking-oil refinery in France, but did not include any of the Chinese financial institutions suspected of facilitating Iran's oil trade.
In response to US Treasury Secretary Scott Bessent laying out plans for economic asphyxiation of Iran, expanding Washington's secondary sanction threats and warning of dire consequences for countries that do not join the campaign, Chinese Foreign Ministry spokesperson Lin Jian said at a press briefing on Tuesday that China has made clear on many occasions its firm opposition to illicit unilateral sanctions that have no basis in international law or the authorization of the UN Security Council. 
"Economic warfare and maximum pressure provide no solution. On the contrary, they only serve to fuel tensions and lead to risk spillover, which will disrupt the global economic and financial order, and harm the legitimate rights and interests of other countries," the spokesperson said. 
The pressing task is to facilitate the deescalation of the situation and return to dialogue and negotiation as soon as possible, Lin said, adding that China will do everything necessary to firmly safeguard its rights and interests, Lin added. Lin also said China's cooperation with Iran is conducted within the framework of international law, thus should not be disrupted.
When asked whether China has received any such timeline, as the US stated it would give countries a timeline on when to shut down the actions that it has identified, and how China intends to respond to the relevant announcements by the US Treasury involving China-based entities and individuals, Chinese Foreign Ministry spokesperson Lin Jian stated on Tuesday that China is closely following the developments, and will do everything necessary to firmly safeguard our rights and interests.
In May this year, China's Ministry of Commerce issued a blocking ban prohibiting any recognition, enforcement or compliance with US sanctions imposed on five Chinese companies on the grounds of their alleged involvement in Iranian petroleum transactions.
Relying on its financial hegemony and long‑arm jurisdiction, the US enforces unilateral sanctions with no basis in international law. Such measures severely undermine fundamental consensus for international trade and erode the existing international order, Zhou Mi, senior research fellow at the Chinese Academy of International Trade and Economic Cooperation, told the Global Times on Tuesday.
In essence, Washington is imposing its Iran‑focused policies to enterprises across the globe, compelling third‑party actors to fall in line with its diplomatic objectives, Zhou noted.
The latest sanctions would affect a broader range of countries, industries and firms. They will not only draw wider opposition from the international community, but also boomerang on the interests of US‑owned enterprises, he added. 
Fewer levers left 
"We are launching an economic onslaught against Iran's financial connections around the globe," Bessent claimed at a press conference. "Our objective is to sever every economic lifeline" that sustains the country, he said, according to a Treasury release. 
The US Treasury Department said in a release that the new sectoral sanctions determinations target five critical sectors - digital assets, technology, gold, aviation and shipping - that the US claimed Iran has relied on to support its economy.
US Treasury claimed that "any entity that facilitates money laundering or sanctions evasion on behalf of Iran risks being cut off from the US financial system."
OFAC also suspended several general licenses that previously authorized certain remittance payments to Iran and Iranian access to the US cultural and academic system. The office also issued additional guidance on the so-called sanctions risks of bowing to Iranian demands related to shipping in the Strait of Hormuz.
Mohammad Mokhber, an aide to Supreme Leader Mojtaba Khamenei, said in an X post on Monday that Iran's response to US sanctions and pressure will be "more decisive than before."
Iranian Economy Minister Ali Madanizadeh said that Tehran "is and was ready," with a two-year plan to counter Washington's new sanctions. He told state television that "it seems they wished to suffer yet another defeat," per an AFP report. 
Iranian Parliament Speaker Mohammad Bagher Ghalibaf responded in an X post that "the Americans know no one will believe their nonsense," noting that the US is not in a position economically to restrict its relations with other countries. 
Alan Eyre, a distinguished diplomatic fellow at the Middle East Institute, told NBC News that after six months of combat, the US government "has few remaining levers it can use to convince Iran's major trading partners to materially reduce their economic ties."
While Washington's maximum‑pressure campaign may deliver short‑term shocks to Iran's economy, it can hardly "strangle" the country completely, said Liu Zhongmin, a professor at the Middle East Studies Institute of Shanghai International Studies University.
He added that Iran's economic resilience cannot be underestimated. Having borne decades of crippling sanctions from the US and Western nations, Tehran has built substantial experience in sanction‑busting and developed coping mechanisms ranging from basic‑industry self‑reliance and regional trade networks to oil‑for‑goods swaps and non‑US dollar‑denominated trade. Furthermore, the Strait of Hormuz remains a source of strategic leverage for Iran to push back against US pressure.
The expert said that Tehran and Washington are encountering "a battle of wills," and Iran believes the economic costs the US would suffer from a Hormuz blockade would outweigh the damage inflicted on Iran by sanctions.
Washington's "economic strangulation" policy risks ending in failure unless it yields short‑term outcomes, particularly securing the opening of the Strait of Hormuz, Liu added. 
Self-created dilemma
As the US ramps up pressure on Iran, Americans are growing averse to a protracted war.
According to a Reuters/Ipsos poll that closed on Monday, US ‌public approval of the war with Iran fell to its lowest level since the conflict's early days, with just 31 percent of Americans supporting US military action.
On June 18, the US and Iran signed an MoU, under which the two were scheduled to hold negotiations within a period of 60 days, which ended on August 17, to reach a final agreement. However, the talks' fate remains unclear following renewed escalation between the two countries.
Iranian political analyst Mostafa Khoshcheschm told Al Jazeera that the new US sanctions intended to create an "economic onslaught" were a "political show" of intimidation. 
Liu said that by resorting to an "economic strangulation" tactic after miring itself in a fruitless military quagmire over Iran, the US has laid bare its practical predicament and strategic dilemma, and seemingly running out of cards.
Citing sources, CNN reported earlier this month that the US military has exhausted nearly 80 percent of its interceptors for a key missile defense system as senior US military commanders are warning that the Pentagon's munitions stockpile is "dangerously low."
Faced with depleted ammunition stockpiles and insufficient military‑industrial capacity, and amid growing domestic criticism of its Middle East policy, the White House has opted for tough economic measures against Iran, Liu said. "Less costly than military coercion, such moves help Washington strike a tough posture before voters and shun political risks from further military escalation," said the expert.
There is, however, an increasingly obvious paradox in Washington's economic warfare against Iran: the tighter the sanctions, the tighter global energy supplies become, and the higher costs borne by American consumers and businesses, the expert added. 
。而最近的一条消息，终于让小弟 4080 也露了个脸，但很可惜，这是一条坏消息。简单来讲，由于被大家口诛笔伐， NVIDIA 决定取消 4080 12GB 显存版本显卡的发售，4080 16GB 发售日期不变。这可不是我说的，人家官方用的就是 Unlaunching 这个词，好好的一个显卡就这么没了。根据多年的搞机经验，撤销发售已经公布的产品这种情况很少见，差不多一只手就能数得过来。但这个事情，只能说是 NVIDIA 自作自受。事情是这么回事儿，上个月 NVIDIA 不是开了个 GTC 大会嘛，会上那叫一个风风火火，不仅讲了一大堆商用领域的内容，也发布了 4080 和 4090 显卡。

B | 其中的 4080 又有 12GB 和 16GB 两个显存版本，售价分别为 7199 元和 9499 元。怎么说呢，你给显存来一刀我没有意见，毕竟这也不是老黄第一次这么干了，而且显存更低就意味着价格也更低，虽然托尼觉得这次的定价都挺贵的。

C | 因为要知道，上一代 3080 的售价可是 5499 元。既然老黄把 40 系吹的这么厉害，而且还换了新架构，没准这 3080 和 4080 之间 1700 块的差价还真不是随便涨的呢？但问题恰恰就出在这上面，因为一个惨痛的事实是：4080 12GB 和 4080 16GB 不仅显存不同，它们可能压根就不是同一块显卡。

D | 4080 12GB 也许只是一个换了名字的 4070 或者 4070 Ti。想要证明这个说法也很简单，只要把它俩的参数拉出来比较一下就行了。其中最重要的一点就是 GPU 核心不同，4080 16GB 采用 AD103 核心，而 4080 12GB 则是更小的 AD104。我说停停，你俩不是都叫 4080 吗？怎么 GPU 核心都换了？除此之外，无论是缓存、内存带宽还是吞吐量， 4080 12GB 的数值都要比 4080 16GB 要低。4080 12GB 的 CUDA 核心数量就更不用看了，7680 比 4080 16GB 的 9728 个 CUDA 核心数少了 21% 。作为对比， 3080 12GB 的 CUDA 核心数量是 8960。更离谱的是，4080 12GB 的显存位宽也低得可怜，只有 192bit。通常来讲，一块显卡的位宽越大，它一次能传输的数据量就越多。而 192bit 是啥概念呢？RTX 2060 的位宽也是 192bit。

E | 但凡你舍得多掏几百块钱上 2060 Super，那么位宽就能来到 256bit。而它的两个大哥，4080 16GB 和 4090 的显存位宽分别是 256bit 和 384bit，我不理解，但我大受震撼。所以，这次没法拿一个旧款的显卡直接去和 4080 12GB 对比，因为老黄这次的刀法属于是翻车了，各个地方刀的有点参差不齐。至于你要问性能怎么样，其实 NVIDIA 官方有放出过一些对比图。比如在《 微软飞行模拟 》中不开启 DLSS 3 的情况下，4080 12GB 的帧率表现会稍微低于 3090Ti。开启 DLSS 3 后，4080 12GB 的表现有了大幅度提升，帧数超越了 3090Ti，但和 4080 16GB 还是有很大差距。所以你要说 4080 12GB 是新显卡也没错，毕竟采用了新的 Ada Lovelace 架构和台积电工艺，还有 DLSS 3 的加持。但托尼最多只能认为它是一款新显卡，而并非 4080 显卡。

F | 4080 12GB 的性能定位不仅很尴尬，更尴尬的是它 7199 元的价格有点高的离谱了。上一代 3080 的定价是 5499 元，而 3070 也就 3799 元。你说它是 4080 吧，那和 16GB 版本的性能有点不匹配，你说它是 4070 的话，那这价格是不是有点高得看不懂了？最终， NVIDIA 在官网发了个开头提到的帖子，说我们要撤销 4080 12GB，因为我们自己也发现这个名字不对，有两个 4080 是非常让人困惑的。NVIDIA 终于发现这事儿不地道了，这波属于是自己打自己的脸。

G | 而各大显卡供应商傻眼了，我包装都做好了结果你说取消就取消？所以最终的最终， NVIDIA 宣布将会报销 4080 12GB 的显卡包装盒费用。到此为止，4080 12GB 就像从未公布过一样，大概率将会消失在人们的视野里。至于以后怎么办，要么改个名字降价再拿出来卖，要么回炉重造，把刀掉的部分补回来。而对于大多数普通消费者来说，30 系显卡仍然是目前为止的首选，至少在价格上大家都负担得起。
