Hi, need info to help in deciding..

Yesterday I phoned a local computer store.. and they finally have stock of GTX 1660 and also 1660 Super. The 1660 is 400 USD, while the Super is 530 USD.

questions.. does the GDDR6 of the super have a large advantage over the GDDR5 of the 1660? Is it worth paying an additional 130 usd for the GDDR6 of the Super?

Generally the performance of a new generation of "supporting" equipment does not have a huge affect on the true performance. GDDR6 is better, but it is not the only reason the Super varient is going to be faster. Same with PCIe generations, and regular DDR3/4 RAM. PCIe Gen 3 is not saturated, so Gen 4 should not be a deciding factor (yet). DDR3 is worse than DDR4, but the performance change is seen when comparing the CPUs directly, not in the RAM alone. For both GPU and CPU, the RAM will affect the performance, but not on its own. The rest of the part needs to be able to take advantage of the upgraded RAM.

You can just compare the raw performance numbers of those two GPUs, like benchmark FPS in games, and use that to decide if you want to spend the extra $130 for the better GPU. You do not have to particularly worry about the supporting specs, like GDDR5/6, CUDA core count, or even base clock speed, because these differences will be reflected in the performance changes as a whole, so you do not have to compare those specific differences. Certain models of GPU might be clocked faster, and will perform better, but you compare those models to the same GPU in stock form. IE, not 1650 vs 1650 Super at higher clock, you would compare the base speed 1650 Super to an upgraded 1650 Super, to see how the clock speed boost changes the performance of the card over its stock clocks.

TL: DR, Dont bother with the details too much, just use benchmarks/average FPS to decide if the extra performance is worth the extra money.

The Super is 15-20% faster. If value scales linearly for you, then the 1660S may be worth $60-80 extra.

$300 for old-gen stuff that used to retail for $300 or less in some cases is simply out-of-bounds for me.

At $500, you can try your luck getting an RX6600XT or RTX3060/3060Ti, a handful of place occasionally have them on sale around that price.

thanks for the replies. Have read them.

I'm from the Philippines, gpu prices are abysmal over here... and gpu are rare as well. Sure, there are plenty on local online sellers with lower prices than physical stores, but the chance of being scammed is so high - when you see a 200$ 1660 sup (I converted the peso to usd), then it's too good to be true. So it's better to get at mall stores... the store where I purchased a 1050 ti even have a promotional 3 day replacement warranty - they will replace if it breaks down or does not work within 3 days, on top of the basic gpu warranty. Why am I getting a second gpu? It's because have two pc. Always good to have a backup.

my monitor is 19 inches, only 900P. The only graphically demanding games I play are Genshin Impact and Valorant.. the rest are PS4 titles like KOF XIV and Soul Calibur VI.
