NVIDIA GeForce RTX 3070 Mobile tested on GeekBench – card specification for laptops has been confirmed
Source: Pure PC added 04th Jan 2021Yesterday we informed about the possible specification of three NVIDIA GeForce RTX graphics cards 3000, which as the first ones will appear in laptops next year. I am talking of course about GeForce RTX 3060, GeForce RTX 3070 and GeForce RTX 3080. However, the said specification was not confirmed in any way and we did not know if there would be such noticeable differences between desktop and mobile systems. It seems that in the case of the middle card – RTX 3070 – we already have confirmation of previous reports. It is about using the GA core 104 with 5120 CUDA cores instead of 5888 as is the case with a desktop graphics card. The entry for the HP OMEN laptop 15 in the GeekBench database confirms this information.
HP OMEN laptop appeared in the GeekBench database 15 refreshed with NVIDIA GeForce RTX 3070 (Max-Q?). The disclosed specification confirms the use of GA core 104 with 5120 CUDA cores.
GeekBench may not be the best tool to measure performance, but in this program you can often come across interesting information about the specifications of upcoming processors or graphics cards. There are two entries in the benchmark database regarding the new version of the HP OMEN laptop 15 with 8- Intel Core i7 – 10870 H processor and NVIDIA GeForce RTX graphics card 3070. The reported core clock is 1290 MHz, but we don’t know if this is for the Max-Q variant or the regular GPU version.
Interestingly, GeekBench reveals that the mobile GeForce RTX 3070 actually equipped with 40 Streaming Multiprocessors blocks (SM), which in the case of the Ampere architecture translates to 5120 CUDA FP cores 32. The mobile counterpart will therefore have a total of 8 SM blocks disabled from the GA core 104 – full has 48 blocks, while desktop RTX 3070 has active 46 SM blocks. The laptop version of the card will also have 160 Tensor cores, 40 RT units, 160 texturing units and 84 rendering units. In the GeekBench test alone, the mobile GeForce RTX 3070 achieves results between desktop GeForce RTX cards 2020 and RTX 2080 SUPER. Due to the lower clock speed of the laptop versions, the mobile RTX 3070 in the same test should get a result slightly better than the RTX 2080 SUPER, used in notebooks. The official presentation of the Ampere architecture for laptops will take place on 12 January.
