Another day, another Blackwell performance leak. As we inch closer to their official release, more and more benchmark results keep popping up on the internet. Now, a fresh Geekbench OpenCL listing seemingly sheds light on the performance brought to the table by the RTX 5090 Laptop GPU, housed in a Razer Blade 16 alongside a Strix Point APU. However, be warned - the following results depict the RTX 5090 laptop running at only 1515 MHz, which makes it significantly slower than what it is capable of when allowed to run at full tilt, likely to be somewhere around 2100 MHz.
As such, the RTX 5090 Laptop managed a score of only around 91,000 points - almost half that of its predecessor's typical score of 179,000 points according to Geekbench. This likely indicates that the laptop was running on battery power, which would make sense considering the abysmal result. At least, thanks to this listing, we do get to confirm the specifications of the RTX 5090 Laptop GPU - 82 SMs, which means a total of 10,496 CUDA cores, and 24 GB of GDDR7 VRAM. The RTX 4090 Laptop, on the other hand, packs 9728 CUDA cores, putting the RTX 5090 Laptop ahead by around 7.87%. The 150-watt RTX 5090 Laptop also clocks at 1455 MHz at an 80-watt TGP, and 2040 MHz at 150 watts. This does align with what we are witnessing from the aforementioned RTX 5090 Laptop listing, confirming that it is indeed in some kind of low-power mode.
