苹果最新款iMac外观与上一代几乎相同，但该公司为其24英寸一体机台式电脑搭载了全新的M6芯片，承诺带来更快的图形处理能力、更强的运算性能，以及设备端AI性能的大幅提升。
Apple’s latest iMac looks much like the previous one, but the company has packed a new M6 chip into its 24-inch all-in-one desktop, promising faster graphics, more processing power and a substantial boost in on-device AI performance.
新款iMac于周三在35个国家开启预售，11月6日起开始发货并在门店上架。
The new iMac is available to pre-order from Wednesday in 35 countries, with deliveries and in-store availability starting on November 6.
熟悉的设计保持不变，包括纤薄机身和七种配色：蓝色、绿色、粉色、黄色、紫色、橙色和银色。大部分变化都在内部。
The familiar design remains intact, including the thin body and seven colour options: blue, green, pink, yellow, purple, orange and silver. Most of the changes are under the hood.
M6芯片最高配备12个CPU核心和12个GPU核心，比上一代机型所用的M4各多出两个核心。苹果根据自身测试声称，它提供了所有电脑中最快的单核CPU性能。
The M6 chip comes with up to 12 CPU cores and 12 GPU cores, two more of each than the M4 in the previous model. Apple claims it delivers the fastest single-core CPU performance of any computer, based on its own tests.
更大的变化在于芯片处理AI的方式。每个GPU核心现在都内置了一个神经加速器，旨在加速AI工作负载，并与16核神经引擎协同工作。
The bigger change is how the chip handles AI. Each GPU core now includes a Neural Accelerator designed to speed up AI workloads, working alongside a 16-core Neural Engine.
苹果表示，这一组合使设备端AI任务的速度比搭载M4的iMac快至多五倍。照片编辑中的图形性能提升至多两倍。
Apple says this combination makes on-device AI tasks up to five times faster than on the M4 iMac. Graphics performance in photo editing is up to twice as fast.
苹果的其他性能宣称包括：Microsoft Excel中的电子表格运行速度提升至多1.5倍，光线追踪游戏运行速度提升至多两倍，存储读写数据的速度提升至上一代的两倍。
Apple’s other performance claims include spreadsheets in Microsoft Excel running up to 1.5 times faster, ray-traced games running up to twice as fast, and storage reading and writing data at up to twice the previous speed.
该公司还瞄准了仍在使用旧款台式电脑的用户。它表示，M6 iMac比最受欢迎的英特尔芯片iMac快至多18倍。
The company is also targeting people still using older desktops. It says the M6 iMac is up to 18 times faster than the most popular Intel-based iMac.
与2021年发布的M1机型相比，苹果声称Excel性能提升至多2.5倍，设备端AI性能提升至多12倍。
Compared with the M1 model released in 2021, Apple claims up to 2.5 times the performance in Excel and up to 12 times the on-device AI performance.
24英寸4.5K显示屏没有变化，最大亮度为500尼特。选择12核配置的买家可以选配纳米纹理玻璃，以减少眩光。
The 24-inch 4.5K display is unchanged, with a maximum brightness of 500 nits. Buyers choosing the 12-core configuration can opt for nano-texture glass, which reduces glare.
新款iMac在连接性方面获得更大幅度的升级，支持Wi-Fi 7和蓝牙6，而12核版本还增加了2.5千兆以太网和四个雷雳4端口。它还可驱动两台外部6K显示器。
Connectivity gets a more substantial update as the new iMac supports Wi-Fi 7 and Bluetooth 6, while the 12-core version adds 2.5 Gigabit Ethernet and four Thunderbolt 4 ports. It can also drive two external 6K displays.
此外，该公司保留了1200万像素的人物居中摄像头、六扬声器音响系统和三麦克风阵列。产品附带配套键盘以及鼠标或触控板，12核机型配备带触控ID的键盘。
Moreover, the company has kept the 12-megapixel Center Stage camera, six-speaker sound system and three-microphone array. A matching keyboard and either a mouse or trackpad are included, with the 12-core model getting a keyboard with Touch ID.
“iMac再次提高了标准，”苹果硬件工程副总裁雪莉·戈德堡表示。
“iMac raises the bar yet again,” said Shelly Goldberg, Apple’s vice president of hardware engineering.
这款台式电脑搭载macOS 27出货，该操作系统将苹果全新的AI驱动Siri引入Mac。该助手可以回答问题、搜索信息、邮件和照片，并跨应用执行操作。
The desktop ships with macOS 27, which introduces Apple’s new AI-powered Siri to the Mac. The assistant can answer questions, search through messages, emails and photos, and perform actions across apps.
Siri AI仍处于测试阶段，支持六种语言，并设有每日使用次数限制。苹果计划稍后提供付费的额外访问权限。该助手最初随iOS 27.2登陆iPhone。macOS 27还包含写作工具以及按主题整理Safari标签页的功能。
Siri AI remains in beta, supports six languages, and comes with daily usage limits. Apple plans to offer additional access for a fee later. The assistant first arrived on the iPhone with iOS 27.2. macOS 27 also includes writing tools and a way to organise Safari tabs by topic.
这些价格与M4 iMac在发布前夕的售价一致，但高于该机型的原始价格。
Those prices match what the M4 iMac cost immediately before launch, but they are higher than the original prices for that model.
据EveryMac报道，由于AI数据中心带来的需求推动内存和存储成本上升，苹果在6月将iMac价格上调了200美元。在涨价之前，最便宜的机型售价为1299美元。
Apple raised iMac prices by $200 in June as memory and storage costs climbed amid demand from AI data centres, according to EveryMac. Before that increase, the cheapest model cost $1,299.
苹果还表示，新款iMac的支架采用100%再生铝，其磁体采用100%再生稀土元素。
Apple also said the new iMac’s stand uses 100% recycled aluminium, while its magnets use 100% recycled rare earth elements.
iMac并非唯一获得更新的Mac：苹果还发布了M6 MacBook Pro。与此同时，其新款折叠屏手机因屏幕开裂问题引发抱怨。
The iMac was not the only Mac to get an update: Apple also unveiled an M6 MacBook Pro. Meanwhile, its new foldable phone has attracted complaints about cracked screens.
