When Intel took the lid off of Ice Lake, we noted that the performance data for the CPU was complex. On the GPU side of things, Ice Lake is a huge leap forward, with substantially higher performance than anything we’ve seen from Intel integrated graphics before. The CPU, however, was a rather mixed bag. When restrained to a 15W TDP, Ice Lake CPUs weren’t necessarily faster than the Coffee Lake chips they are intended to replace and were often somewhat slower. If you give the CPU additional headroom, this problem resolves — but of course, giving the chip more power to play with has a negative impact on heat and battery life.
When Intel invited reviewers to test Ice Lake, the test systems it offered had a toggle switch to flip from 15W to 25W envelopes. That’s how PCMag and other publications were able to test the laptop in both modes, as shown below:
Users don’t usually have this kind of option. TDP ranges are typically pre-defined by the OEM and are not something that the end user can modify, for obvious reasons — cranking up laptop TDP is a good way to overheat the system if you don’t know what you’re doing and if the laptop isn’t specifically designed to run at the higher power level. To the best of our knowledge (until today), no consumer laptop could actually change its TDP values on the fly. At the Ice Lake testing event, Intel told reviewers that the Ice Lake laptops sold at retail wouldn’t have this option, either.
There appears to be at least one exception to this rule, however. The Razer Blade 13 will have an adjustable TDP that can be configured through Razer’s Synapse software. Supposedly this capability has always existed, going back to the original Razer Blade. If this is true, it’s not something the company previously seems to have highlighted — Google doesn’t bring up any results referring to an adjustable TDP on previous versions of the Razer Blade, unless you count the fact that the laptop would down-clock under load in some circumstances. To be clear, the ability to run the CPU in a lower power envelope under load isn’t the same thing as being able to voluntarily put it in a higher TDP mode and operate it with additional power headroom.
Given that Intel had already told reviewers not to expect adjustable TDP ranges as a major laptop feature, this raises the question: Is this specific to Razer, or will we see more laptop manufacturers taking advantage of these new capabilities? Will Intel make adjustable TDPs a feature that high-end customers can shell out for if they want the option?
Razer’s website for the new Blade states that the system will use a 25W Ice Lake CPU, but does not mention anything about the system being adjustable within a 15W versus a 25W power envelope.
