Intel Ice Lake Gen 11 Graphics 15W Vs 25W Performance Comparison
So, we got an opportunity to try out Intel's upcoming Ice Lake Gen 11 graphics and we noticed a convenient looking menu showing 15W and 25W TDP buttons. As you may know, Ice Lake will be shipping in 25W and 15W variants and here we had the opportunity to try out the effect of configurable TDP on a first hand basis. So we whipped out the camera and fired up the most easily accessible game: CS: GO.
Intel's Ice Lake Gen 11 GPU nets 43% more FPS in 25W mode, configurable TDP comparison
The 15W configurable TDP is what is likely going to end up in very thin ultrabooks, while the 25W option is going to end up in notebooks. If this single data point from CS:GO is to be believed, then you are looking at roughly a 40% performance improvement over the 15W part. The tests were running at 1080p resolution on an async panel and the game play was buttery smooth in both cases. Here is the average fps we saw during the session (both frames are the same):
As you can see, in 15W mode, the Ice Lake GPU is able to output a constant stream of fps hovering at around 67-69 while as when we shift it to 25W mode, it instantly jumps to stabilize around 97-100 fps. This was a static scene with the player standing still so any variation is likely the result of dynamic clocking of the GPU according to the ambient temperature and airflow. All in all, this is pretty great performance for an integrated GPU.
Considering the fact that Ice Lake's GPU supports adaptive sync, low refresh rates are going to look much smoother than a traditional display and the ample amount of horsepower (for an iGPU) will allow it to get by in gaming situations where most traditional iGPUs would have been a stuttering mess. The company is shipping 10nm Ice Lake processors right now and they should be on the shelves as soon as partners are able to integrate them into laptops.
Ice Lake's Gen 11 graphics are based on the 10nm process and are designed using the 2x strategy where Intel expects to double the integrated performance on a regular cadence. The eventual aim is to capitalize on the fact that Intel's iGPUs own the majority of the GPU market. You can read more about our coverage of the Ice Lake architecture and Gen 11 graphics over here.
