Intel Kaby Lake Core M3-Y730 – How much are you really getting?

This year, Kaby Lake is to dethrone last year’s fastest Tablet Chipset Skylake. But how much are you really getting in terms of performance and value?

This article aims to answer the following questions:

  1. How much improvement is the new Chipset compared to the Skylake?
  2. How is the Gaming Performance?
  3. Price to performance, which offers the best value

Short description:

The Intel Kaby Lake Core M3-Y730 is the successor to Skylake Chipset and comes with three several upgrades. The Table Below summarizes the specs

Gen7 0.9 - 2.6GHz Dual Core 14nm

GPUIntel HD515 (300-850MHz)Intel HD615 (300-850MHz)
MemoryDual Channel 1866MHz, 1600MHzDual Channel 1866MHz, 1600MHz

The Intel Kaby Lake Chipset has a much faster boost clock, up to 2.6GHz, instead of 2.2GHz on the Skylake Chip. This translates to roughly 10% performance boost and you can clearly see it on the benchmark test below. Also, both chips support the same memory module, Dual Band and up to 1866MHz.

The GPU on the other hand, just gets a 50MHz boosts, which is a bummer. Similar performance? Yes, identical even, the high clock much less a meager one, doesn’t really translate to more fps, but you can still game on it, as the old Intel HD515 is still a great integrated GPU and can play most Mainstream games at native resolution and adjusted details.


Both chips have the same TDP and thus, it does have similar power consumption as well as maximum temps. I can’t compare thermals in here because, it wholly depends on the thermal design of the tablet or Ultrabook. For example, the Xiaomi Mi Air 12 has very good thermal dissipation, meanwhile the Cube i7 Book and Cube Mix Plus does not. So it would not be a great comparison. All you need to know is that both chips are identical when it comes to power consumption and thermal threshold.

Thermal Throtting?

So far, I have not yet encountered Skylake or Kaby Lake powered Tablets that had issues with this performance. Although it does get hot, around 88°C, in particular the Cube i7 Book/Cube Mix Plus. Performance is still 100%.

Skylake sample was based on the Xiaomi Mi Air 12 Benchmark scores and the Kaby Lake Chipset was based on the Cube Mix Plus. It can be seen that there is an obvious increase in performance. And frankly, you do notice that the Kaby is slightly faster. When you go through the menus, opening apps, and multitasking. I think it is a good 10% better than the Skylake Chip. The extra boost clock I think definitely helps in Single Core and Multi Core Tasks.

However, in terms of GPU, the 50MHz increase on the Intel HD615 seems to have little effect on gaming. As gaming experience is relatively identical. The fps average remain the same. Also worthy to mention, that the Intel HD515/615 isn’t a gaming GPU, so you should not expect it to max out games. Mostly, you can play low to mid-end Games, and mostly Mainstream games work fine. Such as Dota 2, LOL, CSGO, BF4, COD. Other games more 3D intensive games like GTA V, Tomb Raider will struggle. The target is 60 or at least it doesn’t dip 30. And in this case, you will probably run all the games at the lowest setting possible for the best results.

So what are you getting with the new Intel Kaby Lake Chipset?

The faster clocked gives it around 10% improvement, which isn’t really much, but you do notice it when using the tablet. This upgrade however is only on the CPU, because the GPU performance is about the same, no real benefits. So, in terms of price to performance, I think Skylake still has the upper hand on this one. Simply because it is cheaper. If Kaby prices will go down, to $300 or less, then this would be the better choice. But you should note, that Skylake is about to be phased out, and more Tablets and Ultrabooks will be coming out soon, and hopefully with bargain prices.
