Pretty new to this forum so I don't know if I'm wording this correctly.
I recently received a Lenovo Z51-70 with specs including a 5th generation Intel Core i7-5500U Processor and AMD Radeon R9 M375 4GB GPU, as well as 8 GB for its Ram.
For a while I've been doubting the websites saying that the R9 M375 has 4 gigabytes of video card memory due to some disappointing performance when gaming. I know the laptop's strange features such as performance becoming significantly slower when the power adapter is plugged off as well as the GPU not recognizing some older games, but I managed to find solutions to those.
I've only recently managed to try and figure out the amount of memory both the display devices the laptop had using CPU-Z. The results were pretty strange.
The memory size is far from 4 GB.
Even stranger is how Intel Graphics seems to have the said 4 GB Vram.
Can anyone clarify what's this about? I've seen multiple websites say that the R9 M375 GPU does indeed have 4 GB of memory, although there is a common variant that has 2 GB but that's still twice the amount I'm seeing here.
