After entries on Nvidia’s upcoming GeForce RTX 3070 for notebooks, a result for the mobile one can now be found in Geekbench’s online database Find GeForce RTX 3080. The benchmark has 48 read out shader multiprocessors from the graphics chip, i.e. 6144 Shader cores. Added to this are 16 GByte graphics memory.

The Geekbench run was made by a user with a ROG Zephyrus notebook, which on the CPU side was running on AMD’s not yet announced Ryzen 9 5900 H sets – presumably a Zen 3 combo processor with eight CPU cores and integrated Vega graphics unit (code name Cezanne). Found the entry of the Twitter user “TUM_APISAK”.

Behind the desktop RTX – 3080 With 6144 shader cores, the mobile GeForce RTX 3080 close to the desktop RTX – 3070, which uses 5888 shader cores. 6144 can be fully expanded with the ampere graphic chip GA 104 to which also GByte RAM on 256 data lines would fit. The desktop RTX – 3080 with GA 102 – GPU, 8704 shader cores, 320 – Bit interface and usually higher clock frequencies should be significantly faster.

Geekbench data for the mobile GeForce RTX 3070 already suggested that the graphics chips should be trimmed more than with desktop PCs. The notebook model therefore has 5120 shader cores. The reason for the limitation could be the power consumption, because the RTX – 3000 – graphics cards for desktop PCs are significantly more power hungry than their predecessors . In (tower) cases this can be compensated for by space for cooling and powerful power supplies, not with notebooks.

Back to the old days In recent years, Nvidia has relied on largely similar GPUs in desktop PCs and notebooks. The GeForce RTX 2080, for example, used in both cases 2944 Shader cores that GeForce GTX 1080 previously 2560. Only the GPU clock frequencies were reduced in favor of efficiency.

The 3000 generation, however, reminds us earlier years – the last was the gap between desktop and mobile in the year 2013 with the 700 series so big. At that time the GeForce GTX 700 came with 2304 Shader cores therefore, the GeForce GTX 780 M with 1536.
