At CES earlier this year, Nvidia announced that just like the preceding GTX 10 series of laptop GPUs, their 20 series RTX laptop GPUs would be slightly cut down from the desktop variants (along with the Max-Q variants for ultra-thin notebooks). The specifications weren’t made public, but it was however announced that the laptops with RTX 20 series GPUs would be available from the 29th of January. Today, two days away from launch, Nvidia has finally announced the specifications for the mobile variants of the RTX 2080, RTX 2070 & RTX 2060.
To kick things off, all 3 GPUs sport the exact same number of CUDA cores as their desktop equivalents. This means that the mobile RTX 2060 has 1920 CUDA cores, the RTX 2070 2304 & the RTX 2080 tops out with 2944 CUDA cores. No downgrades here. The memory speed also remains the same across all three cards at 14GB/s. However, this is mostly where the similarities stop. The clock speeds (base & boost), Giga-rays/s, RTX-OPS & most importantly (and expectedly) the TDP have been reduced.
|RTX 2060 DESKTOP||RTX 2060 LAPTOP|
|BASE CLOCK (MHz)||1365||960|
|BOOST CLOCK (MHz)||1680||1200|
|RTX 2070 DESKTOP||RTX 2070 LAPTOP|
|BASE CLOCK (MHz)||1410||885-1215|
|BOOST CLOCK (MHz)||1620||1185-1440|
|RTX 2080 DESKTOP||RTX 2080 LAPTOP|
|BASE CLOCK (MHz)||1515||735|
|BOOST CLOCK (MHz)||1710||1380|
As expected, the RTX mobile series, while having the same names, core count and memory speeds, will be slower than their desktop equivalents. This is due to their reduced TDP, clock speeds and other reductions that come along with them. What’s interesting though is that Nvidia hasn’t announced the specifications for any of the Max-Q variants. The Max-Q designs usually feature a reduced core count along with further tuned down frequencies.
Laptops featuring the GeForce RTX 2080, 2070, & 2060 hit retail shelves this Tuesday.
