详细释义
处理器配置:联想G460笔记本的核心处理单元基于Intel的Arrandale平台,常见型号包括Intel Core i3-350M和Intel Core i5-430M。i3-350M为双核心四线程设计,基础频率2.26GHz,支持Intel Hyper-Threading技术,提升多任务处理效率;而i5-430M则具备更高的2.26GHz基础频率和Turbo Boost技术,可动态超频至2.53GHz,适用于更 demanding applications such as photo editing and light video encoding. 这些处理器集成Intel HD Graphics,提供基本的图形处理能力,并支持64位计算,确保与 modern software compatibility. 功耗方面,TDP为35W,平衡了性能与能耗,搭配联想独有的散热系统,确保长时间运行稳定。
内存规格:内存模块采用DDR3 1066MHz类型,标准配置为2GB单条或双通道设计,最大支持升级至8GB(通过两个SO-DIMM插槽)。这种内存速度足以 handle everyday computing tasks, and the upgradability allows users to enhance performance for memory-intensive applications like virtual machines or large spreadsheets. 延迟时序典型为CL7,提供 responsive data access, and the non-ECC design ensures cost-effectiveness for consumer use.
存储设备:硬盘选项包括320GB或500GB SATA II接口的机械硬盘,转速5400RPM,提供 adequate storage for OS, programs, and user files, though slower compared to SSDs. 部分高端变体可能配备7200RPM硬盘 for faster read/write speeds. 光驱为内置DVD±RW刻录机,支持CD和DVD media, useful for software installation and data backup. 存储扩展可通过USB外部驱动器或更换内部硬盘实现,但原厂不支持mSATA或SSD直接安装,需用户自行改装。
显卡信息:图形处理部分,基础型号集成Intel HD Graphics,共享系统内存,性能 sufficient for HD video playback and basic gaming at low settings. 可选独立显卡为NVIDIA GeForce 310M,拥有512MB DDR3显存,支持DirectX 10.1 and NVIDIA Optimus technology for dynamic switching between integrated and discrete graphics to save power. This GPU enhances performance for titles like World of Warcraft or older games, but it is not suited for modern AAA games at high resolutions. 输出接口包括VGA和HDMI,支持 external monitor connections up to 1080p.
显示屏特性:屏幕采用14英寸LED背光TN面板,分辨率1366x768 pixels, aspect ratio of 16:9, offering decent viewing angles and color reproduction for its class. 亮度约为200 nits, with anti-glare coating to reduce reflections in well-lit environments. 该显示屏适用于文档处理、web browsing, and media consumption, though it lacks the vibrancy of IPS panels. 整体设计为 matte finish, minimizing fingerprints and enhancing durability.
网络与连接:无线连接基于Atheros或Intel WiFi适配器,支持802.11b/g/n standards, providing reliable internet access with speeds up to 150Mbps. 有线网络通过10/100 Ethernet port, suitable for stable LAN connections. 物理端口包括3个USB 2.0 ports for peripherals like mice and external drives, a VGA port for analog display output, an HDMI port for digital audio/video transmission, a multi-format card reader (SD/MMC), and a headphone/microphone combo jack. 缺少USB 3.0 and Bluetooth in standard models, but these can be added via dongles. 此外,内置 microphone and webcam with 0.3MP resolution, adequate for video conferencing.
电池与便携性:电源系统使用6-cell lithium-ion battery, capacity around 48Wh, delivering approximately 3-4 hours of usage under typical conditions (web browsing and office work). 重量约为2.2kg with battery, and dimensions are 345mm x 235mm x 32.5mm, making it moderately portable for its era. 充电器为65W adapter, supporting quick recharge. The build includes a spill-resistant keyboard and a sturdy hinge design, enhancing longevity for mobile use.
