首批酷睿至尊 7 355 基准测试结果出炉，其性能远不及酷睿至尊 X7

Panther Lake-U Core Ultra 7 与 Core Ultra X7 相比，速度和效率都明显较低

到目前为止，Panther Lake-H 已经证明了自己令人印象深刻的性能，但较低级的 Panther Lake-U 系列却失去了很多前代产品的独特之处。

Review Snippet Laptop / Notebook XPS Ultrabook Panther Lake

2026 款戴尔 XPS 14现已出货，可选择 Core Ultra 7 或 Core Ultra X7 Panther Lake 处理器。我们最近查看了这两款系统不过，价格较低的酷睿 Ultra 7 配置在性能上存在相当大的差距，潜在买家可能需要警惕。

正如我们下面的对比图所示，新的 U 系列酷睿至尊 7 355XPS 14 比酷睿 X7 358H 慢 30% 到 50%。酷睿至尊 7 358H在多线程负载方面要慢 30% 到 50%。由于酷睿 Ultra X7 比 U 系列处理器具有更高的 Turbo Boost 潜能，因此在 CPU 承受压力的最初一分钟左右，较高的性能差距最为明显，但即使考虑到任何节流因素，30% 的差距仍然很明显。

因此，酷睿至尊 7 355 处理器的整体性能更接近于上一代的 Lunar Lake 酷睿至尊 7 258V但 NPU TOPS 性能稍弱。

由于 Panther Lake-U 比 Panther Lake-H 慢，又比 Lunar Lake 新，人们可能会认为酷睿至尊 7 355 的功耗会低于酷睿至尊 X7 或酷睿至尊 7 258V。遗憾的是，事实似乎并非如此。例如，在外接显示器上运行 CineBench R23 xT 时，一旦 Turbo Boost 速度稳定下来，酷睿至尊 7 XPS 14 与酷睿至尊 X7 XPS 14 和联想 ThinkPad T14 Gen 6 对电源的需求几乎相同。因此，当酷睿 Ultra 7 355 和酷睿 Ultra X7 358H 进行比较时，上述 30% 的性能差距并不意味着每瓦性能明显降低的 30% 功耗。
