After Effects on HP

Not a great choice for After Effects because its CPU clock speed, even at maximum sustainable turbo boost, is on the low side. And most 15t's come with only a 1366x768 display, so you will not be able to run any video editing programs properly unless you pay extra money for an upgrade to a Full HD (1920x1080) display. You see, Intel has artifically restricted its 10nm CPU performance to below that of the weakest 14nm tweaked-over-and-over-again-from-Skylake parts. And in some video editing programs, the critical portions of the desktop interface, such as the Export button, becomes permanently buried and inaccessible unless you go for a higher-rez display because the sizing of the desktop windows within such a program cannot be adjusted smaller than the default no matter what.

And this is all because After Effects still cannot fully utilize a multi-core CPU. In fact, After Effects performance begins to flatline out above a 4-thread CPU (the 10nm Ice Lake low-power i7 CPUs have 4 cores and 8 threads, and then, combined with the relatively slow sustainable clock speeds, make for very lackluster performance in After Effects). Plus, the fact that the Pavilion 15t does not offer a choice of a decent GPU even at extra cost is a deal-breaker: You either get integrated Intel Iris Plus graphics or a discrete GeForce MX250 GPU - neither of which is good enough for a video editing laptop. And HP always permanently disables the integrated Intel graphics when its laptops are ordered with a discrete GPU; thus, you cannot use Intel QuickSync decoding and a discrete GPU together (and the MX250 has absolutely no hardware encoder at all due to the GP108 GPU that the MX250 uses, permanently locking such a configuration to software-only encoding).

Simply put, it is a mediocre at best choice for Creative Cloud, and it is too expensive for what it offers.

What are the complete specs?

16gb should work fine for most circumstances.
