One of the ways to see if a processor architecture, whether general purpose or special purpose, is to see how it performs in low power and temperature scenarios. Since the performance per watt is not constant. For NVIDIA, having their GTXs first and RTXs hit their ratings later was key to dominating the gaming laptop market with a market share that could literally be considered a monopoly. Unsurprisingly, such a lucrative business will continue for another year, this time using Lovelace architecture GPUs.
RTX 4080 portable specs have been leaked
With the controversy of the RTX 40 and its high consumption, but paradoxically with better performance per watt than its AMD rivals, we were curious to know what NVIDIA would bet on the RTX 40 for portables. Well, in the Geekbench 5 results database, a laptop appeared, which we know from the fact that its processor is an Intel Core i9-13900HX, with an NVIDIA graphics card which is mentioned in the benchmark as the RTX 4080 laptop.
The bone 12 GB of memory, which will be GDDR6 because GDDR6X with its high power consumption is not viable in laptops, this indicates that the chip used is the AD104. This is the same chip from the also confirmed RTX 4070 Ti that we will see in desktop graphics card form and which is none other than the “cancelled” RTX 4080 12GB that was showcased a few years ago. month. However, although it is the same chip, it is a variant with less capabilities, since there are 58 active units instead of 60 there a boost clock speed of 2010 MHzinstead of 2610 MHz.
Obviously, due to power consumption limitations, laptop graphics cards will always perform worse, as they typically operate at lower voltages, which also limits their maximum clock speed. In any case, we should not only see models based on the AD104 chip, but also on the AD106, the currently unreleased RTX 4060. More than anything due to the fact that although NVIDIA has dropped the price of the RTX 4070 Ti slightly, they are still off the consumer market price.
How is your gaming performance?
Well, in games we don’t know, because OpenCL only measures compute capacity and not the whole when generating graphics. However, for things like Ray Tracing performance, the computing power outpaces the RTX 3070 by more than a quarter, a generational leap that we can consider small, so we’ll have to wait and see how this portable RTX 4080 performs.
It won’t be the most powerful portable RTX 40
Finally, we know that there is a portable RTX 4090, based on the AD103 chip, since it will have 16 GB of graphics memory. Which will have a TDP of up to 175W.
