Well GDDR7 will be faster Ram which will mean you won't need asmuch. But I do like the sound of 16gigs over 12gigs. Yeah I understand to make up the power output would take awhile but that could also lead to the Nvidia card running cooler meaning it most likely have a longer life span ontop of being cheaper to run. It's still a neat advantage. |
Faster ram just effects memory bandwidth.... not how much of it is needed (to play a game at certain resolutions).
This is why people say don't buy the 5070.... because it has to little ram on it.
GDDR7 means the ram can run faster, and use less power (earning nvidia some performance (from memory bandwidth) and some power savings).
However it costs more than GDDR6 (I think?).
So it comes with a trade off... however, it doesn't mean you need less ram pool (in size) because it moves faster.
This just means, you suffer less performance at higher resolutions where memory bandwidth play a bigger role.
Ironically, at 4k the margins close in AMD's favor with these cards.
This means you miss understood what ram is and does, which is fair enough.... that is why I'm pointing this out for you in this post. The it runs cooler because of this is also kinda faulty logic.
The cooling has to do with the power comsumption/heat generated AND how good the cooler is.
Running at less power, you can trade off your advantage, for a smaller cheaper cooler = money saved = more profits.
Which is what NVIDIA choose to do.
This is the same with the GDDR7, by using faster and less power hungry RAM, they can use a smaller bit bus with their chip, while still having good enough memory bandwidth. Thus allowing them to make a smaller cheaper chip (size is smaller as a choice of this = cheaper = more profits).
Everything is just design choices with trade offs, that nvidia usually take for profit margins sake.
Nvidia could choose to not gimp their cards with poor video card ram pools, but choose not too, to force people to buy higher priced cards, and to have better profits on selling the cards. Its all by design, that way. "most likely have a longer life span ontop of being cheaper to run. It's still a neat advantage." Just like there is "designed to fail" concepts that design hardware to last until a bit after warranty lasts, so they can sell you another, when it breaks.
There is something called "Planned obsolescence" where a product loses performance and becomes slower and slower as time goes on.
This is something that plagues Nvidia cards more than AMD ones.
Typically some of this is due to AMD drivers improving more over time, than nvidia ones, that launch closer to prefection (compaired to possible performance you can squeeze out of the card).... however some also think, nvidia actively purposefully make changes that hurt older cards in drivers and such, to force you to upgrade.
This is why there is the expression "...AMD ages like fine wine" when it comes to GPUs.
They give more video card ram (which typically means future proofing) and AMD don't do any of this "planned obsolescence" stuff.
When a generation or two, passes by and you "re-test" (benchmark) these old cards again, against one another, you typically see AMD ones performing better, than they did at launch against nvidia ones. Ei. AMD ages better in terms of performance. |
