Tiger Lake vs. Renoir Intel gave us the possibility to check the brand new high-end CPU for slim notebooks. Intel’s new Tiger Lake chip runs on the new and better integrated graphics card, therefore the gap to AMD could be closed. We’ve a closer look at a development notebook computer from Intel and test the capacities of the brand new chip in various benchmarks and with different TDP configurations.

We tested an “Intel Reference Design System”, that was build for Intel. It really is predicated on the MSI Prestige 14 (in review with Comet Lake) barebone notebook, that may not be accessible for retail. This is a comparatively slim 14-inch laptop, which is slightly raised when you open the lid and sucks in air from underneath. The fan noise was moderate during our benchmark tests. The aluminum chassis did get pretty warm, nonetheless it had not been too bad. We are sadly not allowed to create any pictures of the internals.

We’re able to select three different performance levels for our benchmarks:
Better Battery: 15 Watt PL1 (sustained load, HWInfo: 14.8 W during Blender) and 54W PL2 (28s peak load, HWInfo 54.5W during Blender)
Better Performance: 28 Watt PL1 (sustained load, HWInfo: 27.9 W duirng Blender) and 54W PL2 (28s peak load, HWInfo: 54 W during Blender)
Best Performance: 28 Watt or 36 Watt with Dynamic Tuning (sustained load, HWInfo 35.3W during Blender) and 54 W PL2 (HWInfo 54.7 W duirng Blender)
Intel recommended the mode “Better Performance”, since it is going to be the most representative for production units. We therefore performed nearly all our tests with 28W and only checked individual tests with 15W and 36W (Dynamic Tuning). Dynamic Tuning maintains the 36W PL1 given that the inner temperatures and the “skin” temperatures aren’t getting too much, otherwise it’ll drop right down to 28W.
The tested Core i7-1185G7 may be the high-end model for the launch of the Tiger Lake U generation and will be offering four processor cores (Willow Cove micro architecture), that may run at up to 4.8 GHz. This implies the peak clock is a lot higher in comparison to Ice Lake and really should cause higher single-core performance. In comparison to AMD’s current top models, Intel still uses four cores and prefers to utilize the chip die for a far more powerful graphics unit and (partially) integrated Wi-Fi along with Thunderbolt 4.
If we only consider the processor performance, there can be an impressive advantage over the old Core i7-1065G7 (like in the Dell XPS 13 9300, for instance). When compared to fast AMD Renoir processors, the test system is sitting between your two 8-core chips Ryzen 7 4700U and 4800U – impressive. The high single-core performance really makes the difference here. The i7-1185G7 can beat all of the rivals in the Cinebench Single-Core tests. A good desktop Core i9-10900K or Ryzen 7 3800XT are slightly slower. In the event that you go through the multi-core benchmarks, just like the frustrating Blender test, AMD’s 8-core chips still have a major advantage. However, Intel can close the gap to the Ryzen 5 4500U 6-core CPU, which once more shows the performance potential of the four Tiger Lake cores.
As we’ve already reported through the launch, Tiger Lake will not use fixed TDP limits anymore, but manufacturers can select from 15 and 28W (based on the cooling solution). Including Dynamic Tuning, the CPU may also consume up to 36W for longer periods. Our benchmarks evidently show these TDP settings have an enormous influence on the performance. The single-core performance isn’t influenced that much, as the 15W limit has already been satisfactory for high clocks, however the CPU performance will stop by 27 % or 31 %, respectively, when compared to maximum setting. This implies there it’s still significant performance distinctions from notebook to notebook. You cannot just consider the model designation like i7-1185G7 for the performance you’ll get.
