买家怎么说
Gigabyte GeForce RTX 5070 GAMING OC 12GB GDDR7 Black
技嘉RTX 5070 Gaming OC总体评价良好,许多用户称赞其在1440p和4K下的强劲性能、在建议零售价下的良好性价比以及高效的散热。然而,一些评论报告了导热垫漏液和间歇性黑屏问题,这削弱了整体的热情。大多数从3060或3070等旧卡升级的用户认为这是一次显著提升,尽管有些人注意到缺乏RGB灯效以及偶尔的驱动或编码问题。
优点
- 1440p和4K下性能强劲
- 建议零售价下性价比高
- 散热高效且温度低
- 运行安静
- 相比旧GPU显著提升
缺点
- 导热垫漏液
- 间歇性黑屏
- 无RGB灯效
- 支持和RMA流程不佳
- 高设置下编码问题
Sapphire Radeon RX 7900 XTX PULSE 24GB GDDR6 Black
Sapphire Pulse RX 7900 XTX 因其出色的性价比而广受赞誉,提供 24GB VRAM 和与 RTX 4080 相媲美的光栅化性能,但成本低得多。用户强调其运行凉爽且安静,尽管有些人指出它在通风不良的机箱中会发热,并且需要高功率电源(最低 800W,推荐 1000W)。一些负面评论提到收到了错误物品(键盘而非 GPU)或驱动程序问题,这些问题通过升级其他 PC 组件得以解决。总体而言,它被认为是游戏和 3D 工作的猛兽,但不适合 eGPU 设置。
优点
- 出色的性价比
- 24GB 大容量 VRAM
- 运行凉爽且安静
- 强大的光栅化性能
- 非常适合游戏和 3D 工作
缺点
- 需要高功率电源(最低 800W,推荐 1000W)
- 在通风不良的机箱中会发热
- 功率峰值高达 400W
- 不适合 eGPU 设置
- 报告了驱动程序问题(通过系统升级解决)
