micron has the details on the datasheet about g5's timings that samsung wont provide it.
i may check the timings of these two version of g5 from micron to see whether there is any real improvement or just lossening the timings on new g5 for more frequency oc headroom.

the new g5 from micron has significant headroom for oc. unlike on pascal eg 1070 the micron g5 in general can oc ~150mhz only.
samsung highest g5 version is native 9gbps. while micron has 8gbps only. i was disspointed about nvidia not choosing the 9gbps from samsung but the new micron g5 shows it is capable to do 9gbps or even 10gbps although timings may be worse on micron g5.

revro so quick looking at the reviews and my local central eu prices and 1660 is cca 260eur and 1660ti is 300eur including VAT.

difference in performance seems cca 20% so those 40 eur more are very good value

gt86 The problem is just... Where is the competition for the 1660?

Lets hope the best for Navi.

RX 590 Nitro down to $219 :-), long live competition!

It's one thing to have some "excessive" GDDR5X laying about that can be redirected to a card that's on the tail end of its lifespan and going EOL within a few months, it's another thing to commit to using GDDR5X on a new $219 GPU that will be sold by the hundreds of thousands if not millions over the next couple years.

fwiw i've never seen the issue for years using vga/hdmi/dvi connections w/570,780,780ti,980ti. though i have always set color range to full in the NVCP for color banding in movies but never seen the "washed out" claims many have made.

but last night i connected to the DP port (first time ever for DP) and oh boy! until i set the NVCP to 32/8/RGB/full it looked like my cheap TN panel TV (via igpu hdmi) was the IPS screen. i have no idea why DP was so worse . .but it was. i had though it was more "user perception" until then.

again, never used DP and never saw it before and the NVCP settings corrected it, but it was shockingly bad.

The pricing of 1660Ti vs 1660 is very close each other this time.
I think the GTX 1660 Ti is a better buy as memory bandwidth gets utilized more. There's a few times where the GTX 1660 is only 10% faster than GTX 1060. These happen to be the titles where the GTX 1660 Ti is on par with Vega 56 due to the memory bandwidth and DCC (Delta color compression).

By increasing the GDDR5 memory speed by 22% this helped to boost frame rates by 11% in Apex Legends. Not bad considering how small the core overclock was. Clearly the GTX 1660 is memory limited and squeezing the most you can out of the GDDR5 is an easy way to boost frame rates.

It's a similar situation on GTA V , The Division 2 (DX12) , Shadow of the Tomb Raider (DX12) , Dirt Rally 2.0 and such

If it had 9Gbps GDDR5 it might have been better but in its current state it exists only to kill off RX 590 / RX 580 and GTX 1060 6GB and 3GB.
