联想军团 7i 蒸汽室冷却 – 已测试热性能!
空气从下面朝后侧的通风口进入，从后角和左右两侧朝后侧排出。, 里面有几个风扇和一个蒸汽室. 冷却 器, 虽然, 似乎更便宜的 7i, 同 2060 graphics and below just has standard heatpipes., 联想Vantage软件允许您在不同性能模式之间进行选择, 其中, 从低到高, 安静, 平衡和性能模式。. 您也可以通过按函数和 Q 在它们之间交换, and the light on the power button will change to reflect this.. 不幸, its not possible to change, 风扇, 速度, manually and undervolting is disabled, which seems to be the case with many 10th gen laptops.. 虽然RTX 2070 是最大 Q, 其使用 Nvidias 新的动态提升, 这意味着功率限制, 可以提升更高， 具体取决于. 如果有可用的电源。, 我看到一个 105 仅 Gpu 压力测试中的瓦特平均值, 但它将更少与 Cpu 活动. 热敏测试与 21 摄氏度. 环境室, 温度. 空闲结果降低. 底部正常. 最坏情况. 使用 Aida64 CPU 应力测试进行了压力测试, CPU 只选中，并且在最大设置下使用天堂基准. 同时, 而游戏测试与看看狗 2, 我发现它使用, a good combination of processor and graphics. Quiet mode was the coolest on the CPU, 虽然, 游戏时, the GPU temperature was higher than others, but no GPU thermal throttling was Observed.
The CPU, 另一方面, was thermal throttling any time it was listed at 94 摄氏度, and this was happening in the highest performance mode with highest fan, speed and only removed while gaming with the cooling pad.. 这些是运行相同测试时的平均时钟速度. 一般. The GPU speeds were better in performance mode and we see the CPU speeds increase as we step up through the modes., 即使使用冷却垫, 虽然, were seeing 3.6GHz over all 8 核心. 在此工作负载中, so not amazing, though Id expect better results with the 6 core CPU configuration as there are fewer cores to power. Quiet mode limits. The processor to 25 瓦. PL1 raises up to 45 watts in balanced mode, but as thermal limits were hit in this stress test were not reaching that.. Pl1 then raises up to 55 性能模式下的瓦数, 但再次, for the same reason: its not being reached.. The GPU results were a bit all over the place. I think this might be due to dynamic boost, as the stress test was running it at 80 瓦. 然后 90 and above in performance mode. With the CPU being smashed, 虽然, were not seeing the GPU run at its 105 功率限制. In a CPU, only stress test with the GPU now idle quiet mode, still caps, the CPU to 25 瓦. 然而, balanced mode now boosts this to 60 瓦。. Although performance mode boosts this up to 85 watts in this long term, stress test thermal limits were being hit.
This would be less of an issue for shorter burst style workloads, though so its still useful to have those higher power limits in place.. Even in this CPU only workload, the all core 4.3GHz turbo boost speed of the i7 isnt being hit due to thermal limitations. Ive used Cinebench to show you how these different modes, perform., 单, core performance, doesnt change too much and then performance mode isnt much higher than Balanced for multicore due to thermal limits., When we look at how this stacks up against others well its the lowest multicore result. I have for an 8 core laptop so far, so those thermal limits really seem to be holding it. 返回. 有, not that much difference in a game when comparing the different performance modes, though the cooling pad still did help out a little. Presumably as temperatures are still a limitation in this test.. 同时, 当, compared to other laptops, the performance appears to stack up ok.. If you want to see more gaming benchmarks from the Lenovo 7i check the card in the top right or link in the description where Ive tested 20 游戏在所有, 设置级别。. 至于外部温度, 在那里， 你实际上会把你的手在安静模式下空闲, 它是在低 30 年代相当标准。, 随着压力测试的运行， 它得到到 40 年代中期在中心. Wasd 仍然很酷, 虽然。, 逐步进入平衡模式, 中间现在只是暖和一点.
在性能模式下. 其类似, 但只是凉快一点 – 这是由于球迷越来越响亮 – 让 – 听一听. 空闲时. 球迷只是听到. 压力测试在安静模式下运行, 与其他游戏相比， 它不是太响亮, 笔记本 电脑. 平衡模式更响亮一点. 然后，最高性能模式增加了风扇更多的把总系统噪音接近大多数其他. I test in their maximum performance mode., Although for the most part, the performance in games is pretty good, when both the CPU and GPU are being hit. The processor seems subject to more thermal throttling when compared to many other laptops, Ive recently tested. 但再一次, this would probably differ with the 6 core config.. I did think it would be a bit better due to all the hype of the vapor chamber, 冷却 器. 在 CPU 中, only workloads where the processor is consistently being loaded. The thermal throttling takes its toll, as this is the lowest multicore result from an 8 core laptop Ive tested.. Its unfortunate that further tweaking cannot be made in the way of undervolting, as that could give it the extra edge needed, but that was locked down with the latest version of BIOS.. I think the power higher limits are good, but the thermal throttle cap is still being hit and limiting performance in multicore workloads, which is why using a cooling pad helps in many cases.. This should at least mean that shorter burst style workloads still see good processor performance.
As they can run at higher power levels up until things heat up.
