At CES 2023 earlier this year, Nvidia unveiled its RTX 40 series mobile graphics card. Recently, foreign media were tested against RTX 4080 and RTX 4090 under different power consumption, and the results were unexpected.
It is known thatBoth the RTX 4080 and RTX 4090 have a full power consumption of 150W, and both have a dynamic power consumption of 25W.The game in question was Shadow Samurai 3 at 1440P. The results showed that the RTX 4080 at full power at 150W achieved the same performance as the RTX 4090 at 125W, while between 80W and 150W, the performance of the two cards increased almost in parallel.
It should be noted that the RTX 4080 only needs to increase power consumption by about 20W to achieve a similar level of performance to the RTX 4090 before reaching maximum power consumption.Considering that the notebook equipped with these two graphics cards basically does not exist power bottleneck, there will be no running power consumption, so the ultimate performance of RTX 4080 can be close to or even reach the level of RTX 4090.
This generation of RTX 40 series graphics card, the biggest improvement is energy efficiency. In terms of parameters,The RTX 4080 Mobile has 7,424 cores, 1350-2280 MHZ acceleration, and 12GB of GDDR6 video memory.
The video memory bandwidth is 192bit. With 9,728 cores and 16GB of high-speed Micron GDDR6X video memory, the RTX 4080 desktop Edition delivers up to twice the performance of the GeForce RTX 3080 Ti in modern games; At lower power, performance is more powerful than the GeForce RTX 3090 Ti.
As you can see from the parameters, the RTX 4080 Mobile is not the specifications of the RTX 4080 desktop, but the specifications of the RTX 4070 Ti. The RTX 4070 Ti is identical to the 12GB version of the RTX 4080 that was withdrawn from release by Nvidia.
Equipped with 7,680 CUDA cores and 12GB of GDDR6X RAM, it has 35.8 billion transistors, nearly 8 billion more than the RTX 3090 Ti's 28 billion, but still a far cry from the RTX 4080's 45.9 billion transistors. So the RTX 4080 mobile version is more like the RTX 4070 Ti on a laptop, with the same 192bit video bandwidth.
The RTX 4090 is more like the RTX 4080 desktop version of the mobile graphics card, and in actual testing,Some people control the power consumption of RTX 4070 Ti from 280W to 150W, still can get 90% of the performance, also can see this generation of RTX 40 series graphics card in the energy efficiency of the great progress.
That's why games with RTX 4080 and RTX 4090 are getting so much attention. For this generation of games, the performance will be a leap forward.
In terms of actual performance, the RTX 4090 and RTX 4080 mobile offer a performance improvement of more than 50% over the previous RTX 3080 Ti and RTX 3080 mobile,Thanks to DLSS3.0 and a new generation of optical tracking technology, these two flagship graphics cards are expected to show performance gains.
But compared to the flagship game, some positioning dessert game in the graphics card will choose RTX 4070/60/50 this kind of more cost-effective graphics card, at the same time due to power control and other reasons, resulting in graphics card run power consumption, which may appear users to buy a graphics card with RTX 4070.
However, it can only run to 2/3 power consumption, and the performance of the game is even less than the power consumption of the RTX 4060. Such a situation requires additional attention from consumers.
