And performed better than the "Original" 3080 nvidia had planned on the GA103 chip... Like the current 4080 on the AD103.
Only reason the 3080 was on a GA102 chip was because of AMD had better performance on the 6800xt and the pricing. The real 3080 on AD103 I bet was priced the same as the current 4080 and had 16GB VRAM too or 12GB and the 3080ti real one may have had 16GB on GA102.
The whole 3080 prices was forced on Nvidia by AMD and people forget that and the whole card had to be changed and Nvidia was not going to just give people a GA102 chip without some cutbacks somewhere and we saw where the 10GB VRAM at $700/£650 msrp and the 12GB version had no real MSRP but was selling for $1000/£1000 and the 3080ti 12GB $1200/£1200.
That is why it was crippled to 10GB VRAM as Nvidia was clearly unhappy about giving such a chip for that price and made sure planned obsolescence will kick in quickly and make people update later to the 4080 that they knew would be priced at $1200/£1200 as the original 3080 was planned to be but AMD made sure to mess that up for them, but this generation AMD and Nvidia were clearly working together to hit these price points after what they saw happen with street prices at the time thanks to mining and lockdowns. The greed finally kicked in for AMD too and why we are where we are now.
The £650 price for the 3080 wasn't good considering the cutbacks on it. It just seemed good at the time and as we also know many never got them at MSRP and even to this day they are above msrp almost 3 years later ... which says enough.
The real 3080 chip GA103 ended up in very expensive laptops as 3080ti chips with 16GB VRAM. They were not sold for £650 in laptops..more like £1500 just for the 3080ti gpu in the laptops as could easily be worked out from the price differences from same models to higher gpu versions. From the 3070ti laptop gpu to the 3080ti there was on average a £750-850 difference in price for the same laptop model.
The same 4080 AD103 is the same chip in 4090 laptops .. so you can see what was planned with Ampere GA103 chips .. basically desktop 3080 and laptop 3090 versions but they called it 3080ti instead and this time called it 4090 laptop gpu just to raise the naming tier and the price again.. but really same chips used for the same thing with a sprinkle of Nvidia naming games.
