Recently Intel presented mobile processors Tiger Lake-U. They have preserved the 10-nanometer process, but it has become better, they have preserved a maximum of four cores, but the frequencies have increased significantly. In addition, they are based on new architectures, both processor and graphics.
So what are these processors capable of? Today, the first tests have appeared on the Web, which allow you to form an idea of the top CPU line – Core i7-1185G7. Recall that it contains four cores with frequencies 3.0-4.8 GHz and GPU Xe with 96 computing blocks.
But before reading the results it should be noted that, like many other modern mobile processors, Tiger Lake in each specific notebook can provide significantly different performance due to different power limits. Below you can see the results for the Core i7-1185G7 with TDP of 15W, 28W and even 34W, and the performance is different CPUs. It’s also worth noting that the tests were performed on a reference notebook provided by Intel itself, as there are no serial models with Tiger Lake on the market yet.
So, we can definitely say that Intel has succeeded. The Tiger Lake is really the new generation of processors that should be available on the market. With its four cores, the Core i7-1185G7 is 15-20% behind the eight-core Ryzen 7 4800U, but 15-20% ahead of the six-core Ryzen 5 4500U. It’s true that the latter doesn’t support SMT, but the consumer doesn’t really care – the result is important. At the same time, the Core i7-1185G7 manages to bypass even a high-performance six-core Core i7-9750H, but this is more of a problem of the latter than achieving the first. We can also note that the Core i7-1185G7 is 65% faster than its predecessor, the Core i7-1065G7!
However, these are all results for the Core i7-1185G7 in TDP 28W mode. But if you limit this CPU to 15 watts, and this will obviously be a frequent occurrence, the performance drops significantly. In this mode, the new CPU is only slightly ahead of the Core i7-1065G7 (with TDP 25W) and sometimes even lags behind it and the 15-watt Core i7-10710U. Thus, when buying a notebook with the Core i7-1185G7 or another Tiger Lake-U processor, you should be careful when choosing a model if you want to get maximum performance. Otherwise, it is easier to take something with Ryzen.
As for GPU performance, in 28-watt mode the top Xe kernel performs great, bypassing Vega 8 in Ryzen 7 4800U by 20-40% depending on the game (although there are games with almost no difference). But when the power limit drops to 15W, Xe’s advantage disappears and Vega 8 gets a little ahead. Compared to the same Core i7-1065G7, however, it’s up to twice as fast in 15W mode, while in 28W mode it’s up to three times faster! Considering that Ice Lake is the previous generation of Intel mobile processors, which has the same process, this is a phenomenal result.
One of the sources also notes that in 28W mode the Core i7-1185G7 actually consumes up to 36W, while the eight-core Ryzen 7 4800U consumes 30W. But, again, in each particular notebook, the power limits and cooling system capabilities will still be different, so here you can chew the new Intel product only conditionally.
Taking into account such impressive results of Tiger Lake-U, the upcoming Rocket Lake desktop processors with the same architecture, but on a 14-nanometer process, may well compete with AMD solutions, but, of course, only with the right pricing policy.
