Nvidia's RTX 4090 mobile GPU looks seriously quick, 55% faster than RTX 3080 Ti mobile

[AaronK]

Rumor mill: BenchLeaks on Twitter has shared a Geekbench 5 score of an i9-13900HX laptop equipped with a mobile version of the GeForce RTX 4090. The OpenCL benchmark results are awe-inspiring, with the 4090 outperforming the previous generation flagship -- the RTX 3080 Ti mobile by a staggering margin. In fact, the 4090 mobile is so fast in Geekbench 5, it was able to match a desktop RTX 3090 in the same test.

According to the Geekbench 5 listing, this yet-to-be-released RTX 4090 mobile GPU features nearly identical specifications to a desktop RTX 4080, with both GPUs sharing the same core configuration of 76 CUs, 9728 CUDA cores, and the same 16GB memory capacity. The only difference is the maximum boost clock on the mobile 4090 which peaks at 2040 MHz instead of 2505 MHz, but that is to be expected from a mobile implementation of the 4090.

No additional details of the RTX 4090 mobile specs have been disclosed, but if history repeats itself, all Nvidia is doing here is turning a desktop RTX 4080 into a laptop GPU. This is something Nvidia has been doing for the past few generations of mobile parts, it will use the same GPU dies found in its desktop GPUs and reduce power consumption to fit inside the power and thermal constraints of a notebook chassis.

Regardless of its mobile form factor, the GPU performance appears to be stellar in Geekbench 5's OpenCL benchmark with a score of 210,290 points.

This puts it up there with the fastest desktop graphics cards from the RTX 30 series, including the desktop RTX 3090, beating it by a slim but still noteworthy 2.4% margin. The RTX 4090 mobile also would appear to do well against the desktop RTX 3090 Ti, undershooting it by 8%.

If we were to compare apples to apples, the RTX 4090 mobile also beats Nvidia's 30 series mobile flagship by miles at 55% faster than an RTX 3080 Ti laptop GPU. Although this is still based on an unconfirmed leak, if this GPU is coming out soon we would expect Nvidia to tease it or fully release it at CES in the next few days.

Let's imagine for a second this is indeed a pretty fast mobile GPU... how much are those laptops going to cost now?

Given the ever rising prices of CPUs, motherboards, and GPUs, with the speed of 4000 mobile perhaps gaming laptops are the future as opposed to desktops......If you gotta psend $3k for a midrang ePC why not get a laptop instead?

"This is something Nvidia has been doing for the past few generations of mobile parts, it will use the same GPU dies found in its desktop GPUs and reduce power consumption to fit inside the power and thermal constraints of a notebook chassis."

Hey, who wants to tell aaron that this has been the standard in the mobile space for 15+ years with only a handful of exceptions?

Yeah bs .. how loud? hot hot? how heavy? .. what happens when you game for 45 minutes and then retest.. betcha it slows right down. I'm sure this is a DTR and not anything anyone would call a laptop. more like a luggable.

The L5P has 2 GPUs and one is the 3070m at 130W, the second one is used in power savy mode. The laptop has a 16 inches screen and is very thin and is the lightest gaming laptop I've ever had (I've had 4 in total). I have never had an issue with temperature. The MacBook Pro I use for work usually makes more noise than my gaming laptop. I can play a whole day without issue on recent games, I use laptop supports so my laptops don't run hot and connect them to my ultrawide display. I am happy with my current gaming setup, I could buy a gaming rig but I had to travel a lot during the last few years so this was the most convenient for me. Also if you tell me that for the price of the last gen deskop GPU I can get a laptop that has a GPU that performs as well as a 3090, I will buy that everytime.

It's a 4080 in all but name, how is it a 4090???????

Among this horrendous pricing situation, their laptop GPU speed in rtx 4000 looks simply amazing.
But then again, the prices...
