The trailer for Intel’s amazing success Rocket Lake aroused some curiosity yesterday. SemiAccurate studied the details carefully, and a very interesting detail emerged about what Rocket Lake really is.
7;s article, we discussed bright spots (singular) and low lights (plural). One of the interesting things we noticed is the performance or lack of GPU performance. As you can see below, Intel claims that the older 14nm Gen 9 graphics cards found in these two generations of older devices are 50% ahead of graphics performance. This is disadvantageous compared to the> 2x GPU performance achieved by 10nm Tiger Lake on the same GPU with a fraction of Rocket’s 125W TDP.
Rockets have nowhere to go
This can be easily explained by the back porting process, which brings the worst of the architecture and process. Although SemiAccurate cannot explain why Intel did this instead of using the adjusted 14nm core, we did point out why they were mistaken for even trying to do this. While considering the above slide and some other figures and vague wording, some important clicks were made on the Xe graphics in Rocket Lake.
