I hadn't really paid attention to this, but since it was brought up because Navi 24 doesn't have any HW encode or decode enabled, the mx line doesn't appear to either. The 2050L does so that's another difference between it and the mx590.

Videocardz claims that the 3080 12 GB will be announced tomorrow.

Weird that they wouldn't have announced it at CES. It's not as though they had so many better things to cover.

On the GPU front, NVIDIA is actually using a slightly better version of their venerable GA102 GPU, which now is used across 5 different desktop video cards. The version of the GA102 used here has a slight increase in the number of SMs enabled versus the OG RTX 3080, with 70 SMs as opposed to 68 on the original card. Clockspeeds have also changed a bit; while the official boost clock rating is still 1.71GHz, the base clockspeed for the new SKU is 1.26GBz, 180MHz below the more basic 3080. Ultimately this seems to be a function of TDP, as the additional memory and additional transistors being lit up on the GPU will increase the power needs of the card, especially in a maximum-load scenario.

As for the memory, the increase to 12GB of GDDR6X comes with a matching increase in the width of the memory bus. The RTX 3080 12GB sees GA102’s full 384-bit memory bus enabled, reflecting the addition of 2 more GDDR6X memory chips (64-bits) to the memory bus, bringing the total to 12 chips/384-bits. According to NVIDIA’s specifications, they’re using the same 19Gbps GDDR6X chips here as on the classic RTX 3080, so memory clockspeeds have neither been dialed up or dialed down. So the expansion of the memory bus brings with it both an additional 2GB of VRAM – which will come in handy at 4K – as well as a 20% increase in memory bandwidth. Compared to the 10GB RTX 3080 and its 760GB/second of memory bandwidth, the 12GB RTX 3080 offers 912GB/second of bandwidth.
Looks like there's a price to pay for the larger memory bus and extra VRAM... and it ain't just the MSRP.

The 3080 12GB is in a confusing spot. It has the same memory and TDP as the 3080Ti, but in some cases may be slower than a 3080 due to the lower clock speeds. But than faster in cases where memory bandwidth or capacity is the bottlekneck.

Not that this will matter because the chances of a gamer ending up with one of these cards is nil.

12GB also has more active cores as well, so chances of it being slower in any cases is quite low.

It mainly exists to increase the official MSRP so NVidia gets a bigger cut of the scalping.
And then when the next generation of cards come out, the perf/$ comparison looks better.

Say goodbye to 3080 10 GB price comparisons. The 4080 will be compared to the 3080 12 GB.

If that was the only reason nVidia would have done this a long time ago. We're at 16 months now from the 3080's release.
- They just have to be less blatant about it.

In normal times this chip would have likely been cut down to a standard 3080 10GB a long time ago, but NV has to be inventive with product segmentation to avoid blatantly appearing to be increasing costs when there is so much customer outrage about prices.

What is really mind blowing is that we're still getting product releases for this gen 16 months in. Still don't have the whole stack on either side either.

AMD/NV might be starting to realize that its pointless rushing their next gen of cards into a supply constrained environment and just trickling stuff out to stay in the headlines now and again.

The already did the 3080 ti and 3070 ti.

If not another MSRP booster, what do you think the point of the 3080 12 GB is?

3080 10GB is $699 MSRP
3080 12GB appears to be $1299 MSRP

The cards are going to perform basically the same. You can barely find 10% average performance delta already between 3080 10GB and 3090.

3080 12GB is obviously to cash in. Why would they keep selling 3080 at $699, when it is selling for twice that.

This GPU crap is getting right out of hand. Screw this mining crap, it literally produces nothing and adds nothing tangible. It's as worthless as all the rest of the stock, finance speculation garbage. Just a way yo move money from one place to another, producing nothing useful in the process.

Well here is a quick and dirty review. Pretty much between the 3080 and 3080 Ti and uses very slightly more power and runs hotter than the 3080 Ti.
