RTX-30-Mobile: There are no longer any dedicated Max-Q variants
Source: Hardware Luxx added 21st Jan 2021NVIDIA confirmed that they will only offer three notebook graphics chips in the future, namely the GeForce RTX 3080 Laptop GPU, the GeForce RTX 3070 laptop -GPU and the GeForce RTX 3060 laptop GPU . In contrast to previous generations, NVIDIA deliberately dispensed with a Max-Q and Max-P variant. Although this gives notebook manufacturers greater freedom in designing their own laptops, it makes the purchase much more opaque for customers.
The dedicated Max-Q and Max-P versions of earlier generations were always equipped with a specific TGP. For example, the GeForce 2080 RTX Max-Q had a TGP between 80 and 90 W and that regardless of the configuration of a particular notebook manufacturer. The GeForce 2080 RTX Max-P, on the other hand, came with a TGP of 150 W therefore. With the GeForce RTX 3080 laptop GPU, however, there are no TPG numbers prescribed by NVIDIA, which is why some manufacturers have a TGP of 80 W, while in other gaming laptops RTX 3080 Laptop GPUs with a TGP of more than 150 W are used. The confusion for customers is great, as many companies do not give any reference to the TGP in the data sheet of the respective notebook, which is why it is difficult to find out whether a certain device meets your own requirements until detailed tests are published.
The table summarizes the specifications known from NVIDIA for the laptop GPUs.
NVIDIA GeForce RTX 3080 Laptop GPU | NVIDIA GeForce RTX 3070 Laptop GPU | NVIDIA GeForce RTX 3060 Laptop GPU | |
CUDA arithmetic units | 6. 144 | 5. 120 | 3. 840 |
TGP | 80 – 150 + Watt | 80 – 125 Watt | 60 – 115 Watt |
Boost clock (MHz) | 1.245 – 1.710 MHz | 1. 290 – 1.620 MHz | 1. 283 – 1. 703 MHz |
Memory size | 16 GB or 8GB GDDR6 | 8 GB GDDR6 | 6 GB GDDR6 |
NVIDIA calls it however, four technologies that the company itself describes as the third generation Max-Q. These should be integrated in all GeForce RTX 290 laptop GPUs and include, for example, Dynamic Boost 2.0, which enables the card to distribute the available TGP between the processor and the graphics chip depending on the requirements. Another feature is Whispermode 2.0, which should always offer the best possible performance at a certain fan volume. Resizable BAR and is designed to allow the CPU to access all of the graphics memory to improve performance. DLSS is supposed to increase the performance by the fact that only part of the pixels are actually rendered, the rest is to be supplemented by an artificial intelligence.
