![]() When you look at Kaby Lake G in the context of portable laptops, it does quite well. But those designs come with weight and battery costs. Portability limits you to a maximum of a GeForce GTX 1080 Max-Q laptop.Ĭlearly, when you’re looking at a GTX 1080 Max-Q or GTX 1070 Max-Q laptop, it’s a ton more performance. Let’s turn back to 3DMark Sky Diver, where we tallied up pure graphics scores from various laptops that are actually “portable.” By portable, we mean laptops that are around five pounds, not beefy six- and eight-pound monsters. We could run through a few more gaming benchmarks, but you get the gist: It stacks up nicely against the GeForce GTX 1050 in most games. The Core i7-8705G Kaby Lake G is slightly slower than the GeForce GTX 1050 Ti In fact, in Rise of the Tomb Raider, it’s actually slightly slower than a GeForce GTX 1050. We again see the Kaby Lake G in the Spectre x360 15 in the same ballpark as the GTX 1050 and GTX 1050 Ti.Īlthough Kaby Lake G does well in Tomb Raider and Sky Diver, the reality of modern gaming is that sometimes it may not beat the competition. Middle-earth also tells us it ain’t no GeForce GTX 1060. Middle-earth: Shadows of Mordor also agrees that the Radeon RX Vega M GL in the Kaby Lake G is a pretty decent chip. ![]() In some game loads, the Radeon RX Vega M GL punches well out of its class. The results here speak well for the Core i7-8705G Kaby Lake: It easily outpaces a Core i5-7300HQ with GTX 1050 Ti and a Core i7-7700HQ with GTX 1050 GPU. We’ve found the circa-2013 Tomb Raider, like many older games, can be particularly sensitive to CPU performance. The first is the venerable Tomb Raider at 1080p resolution and set to the Ultimate preset. Going up against more typical workhorse laptops isn’t quite as fun as seeing how the Core i7-8705G stacks up against gaming laptops, so we ran a few games on the Spectre x360 15 as well. With its CPU performance and the Radeon RX Vega M GL, the Spectre x360 15 has a slight edge over GTX 1050 laptops. Intel just spiced up Polaris with Vega elements, including high-bandwidth cache and HBM2 memory. Intel officials declined to comment. We reported earlier this year that although Intel branded Kaby Lake G with AMD’s newest and best graphics “Vega” brand, it appears to be based on AMD’s older stock of Polaris graphics cores used in the RX 580 series. Is it Polaris or Vega? It probably doesn’t matter Kaby Lake G is instead based on an “H” part, which is rated at 45 watts and can run at 56 watts until it heats up. That initially led many to assume that Kaby Lake G was paired with a lower power 15-watt “U” series chip. If the CPU is under a heavy load, the GPU can back off. If the module’s under a heavy graphics load, the CPU can back off. With Kaby Lake G, the power and thermal needs of the CPU, GPU, and the RAM for the GPU are all managed as one. Like Darth and Luke working together to bring order to the galaxy, Kaby Lake G allows for far control ![]() It’s really up to the laptop maker to manage it all. With a traditional separate CPU and GPU, one part doesn’t know what the other is doing. Kaby Lake G also offers more fine-grain power control of the components. The resulting module is a whole lot smaller and thinner than a traditional setup. Inte’s new EMIB is used only to connect the the HBM2 memory with the custom Radeon graphics. Intel uses its EMIB to connect the custom Radeon graphics core with 4GB of HBM2 memory. On Kaby Lake G, a conventional x8 PCIe 3.0 connection joins the CPU to the GPU. ![]()
