Last time we checked how the 8th gen Kaby Lake G member – namely the Intel Core i7-8705G, performs against the 8th Generation Kaby Lake Refresh Intel Core i7-8550U and our final judgment was in favor of the former. So today we decided to compare it to Intel Core i7-8650U and see if it manages to keep its superior position.
Visit our Top Laptop CPU Ranking to check these two and many more CPUs.
We start off with Intel Core i7-8705G which is based on the Kaby Lake G architecture (8th gen) featuring a total of 4 cores and 8 threads. In addition, manufactured through a 14 nm process, the chip operates at 3.10 GHz base frequency and a maximum speed of 4.10 GHz. The specs sheet is complemented by 8MB last level cache, a dual-channel memory controller supporting DDR3L-1600 or DDR4-2400 and a TDP of 65 W. As for the iGPU, here you are presented with AMD Radeon RX Vega M GL (Vega 870, 4GB HBM2) clocked at 931- 1011 MHz.
Now let’s cover the specs sheet of its opponent briefly. Intel Core i7-8650U is part of the 8th Generation (Kaby Lake Refresh) and features 4 instead of 8 cores and 8 threads. Additionally, the base frequencies go up to 1.90 GHz, while the turbo speed can reach up to 4.20 GHz. Other specs include support for dual-channel DDR4-2400/ LPDDR3-2133 memory, 8MB last level cache, 14nm FinFET manufacturing process, as well as TDP of 15W. When it comes to iGPU, you are presented with Intel UHD Graphics 620 clocked at 300-1050 MHz.
Results are from the Cinebench 15 CPU test (the higher the score, the better)
Results are from the Fritz chess benchmark (the higher the score, the better)
For the purposes of this comparison, we have decided to compare the performance of the two chips found in Dell XPS 15 9575 and Dell Latitude 15 5590 respectively. Looking at the charts above, Intel Core i7-8705G shows around 20% better results when it comes to 3D rendering (tested with Cinebench 15). However, the performance of both chips in our Photoshop benchmark test is pretty similar with Intel Core i7-8650U being 6% faster.
To sum things up, both processors deliver quite similar performance, but if we have to name a winner it would be the Intel Core i7-8705G. However, due to the tight battle, we also suggest considering other criteria such as price, battery life, and GPU performance based on your priorities.
