Dell has trimmed the GeForce RTX 3070 in notebooks with AMD processors; version with Intel no

All owners of the model who contributed to the discussion on reddit encountered an identical problem, so it is practically not a matter of several pieces, but the widespread use of GeForce RTX 3070 with 4608 stream processors instead of 5120 Nvidia specifications. Of course, these users were looking for a solution, so they turned to the technical support of a company that at first could not answer them and offered only princely advice such as driver updates. Some bolder mobile graphics have flashed the BIOS of the Dell Alienware M15 R4, a notebook that also features the GeForce RTX 3070, but with 5120 stream processors. After all, the GPU worked (without artifacts) and the performance increased, so it was obviously not just a matter of erroneous detection.

Afterwards, Jarrod’s Tech YouTube channel got a statement from Dell that Nvidia’s OEM partners have the ability to adjust the number of mobile GeForce stream processors to achieve the necessary goals, it was a design choice (and so on, we will forgive the following marketing agreement). This statement probably did not satisfy the user too much, as a class action lawsuit against Dell began to take shape.

But then Dell turned around and “design choice” became “incorrect setting”:

We have been notified of an incorrect setting of the Alienware graphical BIOS limiting the CUDA kernel to the RTX 3070 configuration. This is a bug that we are working hard to fix as quickly as possible. We are rapidly preparing a validated solution and expect to resolve the situation in mid-June. In the meantime, we do not recommend using BIOS from another Alienware platform. We apologize for the frustration caused.

— Alienware spokesperson

So what do we know about the situation:

  • the specifications on the manufacturer’s website do not specify the number of stream processors
  • Alienware first stated that a lower number (4608) of stream processors is the intention
  • users who used BIOS from another model and increased the number of stream processors to 5120 do not report any issues that could indicate that inferior GPUs were used on the M15 V5; very likely there was an intentional shutdown of otherwise functional stream-processors (Nvidia has no version with 4608 stream-processors in the specifications; it probably only supplies models with 5120)
  • the problem concerns the Dell Alienware M15 R5, ie a laptop with AMD Ryzen processors
  • The problem does not affect the Dell Alienware M15 R4, a laptop with Intel Core processors
  • Due to the lower number of stream processors, the Dell Alienware M15 R5 has lower gaming performance at a higher TDP than other notebooks with the GeForce RTX 3070:

According to Jarrod’s Tech, with this change, the notebook lost up to 10% of gaming performance compared to a properly configured version of the GeForce RTX 3070.

It is particularly interesting that notebook models equipped with AMD processors, namely the Ryzen 7 5800H and Ryzen 9 5800HX (R5 models), have experienced this comb, while notebooks equipped with Intel processors, namely the Core i7-10870H and Core i9k-10980HK (R4 models) have GPUs. with 5120 stream-processors. In this context, it is worth noting that Intel’s laptops are popularly used by Intel-based and AMD-based platforms to compare gaming performance, claiming as “The Generation IntelĀ® Core” is the world’s best gaming laptop processor. A total of eight such comparisons based on Dell notebooks were made in presentations at the current Computex, and although they did not specifically address this pair of model lines, it would be worth checking to what extent the “GeForce” configuration in other AMD and Intel notebooks which Intel builds marketing comparisons vary.
