Dell has found themselves in hot water yet again as poor laptop consoomers have sadly discovered that their Alienware M15 R5 laptops with the NVIDIA GeForce RTX 3070 “Laptop GPU” come with fewer than specified CUDA cores.
For those who don’t know, the GeForce RTX 3070 Laptop GPU is supposed to come with 5120 CUDA cores, of course ranging wildly from 80-125 TGP which differs between OEM machines resulting in dramatically inferior performance between what would essentially be identical hardware.
However it would seem that Dell are taking this sort of artificial segmentation to the next level as users discovered that their Alienware M15 R5 laptops featuring the RTX 3070 reported incorrect CUDA core values in GPU-Z.
With GPU-Z reporting the GeForce RTX 3070 featured inside these Alienware M15 Ryzen Edition R5 laptops coming with just 4608 CUDA cores or more rather 36 SM’s as opposed to the 40 SM’s on the actual RTX 3070 Laptop GPU.
Not only does it just end with total CUDA cores but a wary HWINFO screenshot showcases incorrect values comparative to the standard RTX 3070 Mobile GPU as having 36 RT Cores in total, as compared to 40.
Tensor cores are also being reported incorrectly with this nerfed M15 R5 reporting 144 while it should be reporting 160.
Hilariously enough the total ROP count is actually higher than what a standard RTX 3070 Mobile actually has with the nerfed card reporting 96 ROPs while it should have only 80, while TMUs are inline with everything else reporting 144 whereas there should be 160.
Overall this would mean that Dell have essentially lobbed off 10% of your CUDA cores and probably close to that in terms of actual performance compared to a traditional RTX 3070 Laptop GPU featuring the same TGP value.
And of course this sort of issue just so happens to occur for the recently release AMD Ryzen variants of these laptops, honestly Dell’s quality control is a fucking joke but such a travesty like this honestly begs to question whether Dell are taking “kickbacks” from Intel like the good old times meaning that this would’ve been intentional making Intel variants of the M15 R5 seem better by comparison?
Now could this be the result of a rogue VBIOS limiting the effectiveness of the RTX 3070 Laptop GPU which now reports 512 CUDA cores less than standard, or perhaps does the M15 R5 feature slightly cucked GA104 cores to increase yields?
Various other gullible goyim suckered into buying a M15 R5 featuring this nerfed RTX 3070 wish to find an answer to that very question.
Notebookreview user, EepoSaurus decided to answer the call by flashing his Alienware M15 R5 with the VBIOS of the M15 R4 resulting in the lost shaders making their long awaited return back home reporting the correct figure of 5120 CUDA cores once again.
So, the answer has been made clear that Dell have seemingly fucked over Alienware M15 R5 owners with this artificial vBIOS limiting performance, however EepoSaurus reported system instability since performing the flash which is most likely caused by power restrictions considering that OEM manufacturers essentially make gorillions of different BIOSes tailormade for individual machines with various TGP values.
Majority of users who’ve purchased an Alienware M15 R5 aren’t going to be tech savvy enough to understand that there’s even an issue with their RTX 3070 let alone how to actually flash and fix the issue resulting in regaining lost performance.
“We have been made aware that an incorrect setting in Alienware’s vBIOS is limiting CUDA Cores on RTX 3070 configurations. This is an error that we are working diligently to correct as soon as possible. We’re expediting a resolution through validation and expect to have this resolved as early as mid-June. In the interim, we do not recommend using a vBIOS from another Alienware platform to correct this issue. We apologize for any frustration this has caused.”
Since it has now become public knowledge that their machines feature dodgy software, Dell will be releasing a fix for this issue in the coming month or so, but once again majority of users wouldn’t be all that savvy enough to actually go through with a BIOS flash on their own accord.
I suspect as a result of that customers will be wanting to either return or file for an RMA for this clearly defective machine.
