GDDR7? Yes, please!

[EarthDog]

Not sure if this was covered anywhere and I'm mobile now...

...but here's some info on the new vram (rumor!) in upcoming graphics cards courtesy of Techradar.

If you’re not excited about Nvidia’s RTX 5090 and 5080 yet, you will be after seeing Micron’s new VRAM that’s rumored for these GPUs

Micron VRAM revelation turns up the anticipation dial to 11

www.techradar.com

Micron’s GDDR7 will facilitate speeds of up to 32Gb/s and up to 1.5TB/s of bandwidth, which as the manufacturer points out is 60% more bandwidth than GDDR6, so it’s quite a leap.

We’re also told to anticipate a better than 50% improvement in power-efficiency with GDDR7 video RAM compared to GDDR6, so that’s good news, too (especially for next-gen mobile GPUs inside the best gaming laptops, of course).

Micron specifically calls out the benefits to gaming GPUs in its announcement, too, indicating that GDDR7 should hit a better than 30% improvement in frames per second for gaming, both ray tracing and rasterization, as an average across 1080p, 1440p and 4K resolutions.

Boosts in the latter department, 4K, will be more pronounced, and ray tracing at 4K (maxed out with ultra details) should see a huge leap of 3x over GDDR6 according to Micron (and indeed a hike of 50% over GDDR6X, the faster spin on current-gen video RAM).

I like the speed as well and the 50% improvement in power-efficiency. I wonder how high you can Overclock them.

I guess some other websites have the same news, but more or less described with their words. They put wccftech as a source. Sometimes they are right, and sometimes, they just spread rumors. If all the slides are true (it seems like they are), then it looks pretty good. I still wait for ~100W 1440p/4k card

You are right that it could be just crap that floating around.

I mean, recently, fake news with edited slides has been appearing more often around the web, and wccftech is known to be the first leaker on many news or new product releases. Sometimes it's hard to say from where they have all that info. Most other websites just repost everything they find, without checking the source.
I'm not saying that this news is fake as it looks real, especially when you check the wccftech article with all those slides (I think I saw something from that earlier). We have still a couple of months until premiere of new Nvidia cards, so some things may change. Especially in mid/low series it may look totally different than we expect.

Haven't found the original source of the slides but it is happening.

Rumours/leaks of it were already floating around earlier this year so the speed isn't a surprise. Standard has headroom to go even faster in future.

Yeah, I looked at the Micron release to validate things, but since I was mobile, didn't link it up and just used the techradar article I ran into (thanks mac!).

Memory bandwidth and power efficiency are always welcome, but I question the real world results until we get GPUs in hand. Most memory generation upgrades don't yield their full potential for a while. Are we choked for bandwidth on current mid and high end GPUs?

i am pretty sure there was a bigger splash about GDDR7 with Samsung then micron. here are articles from earlier this year, first link is from last year.

Samsung debuts the industry’s first GDDR7 memory chips

The company claims its first GDDR7 DRAM offering can deliver 1.5TBps of bandwidth — 40 percent higher than the previous GDDR6 generation.

GDDR7 from Samsung up to 32 Gbps, 28 Gbps for RTX 50 series There is no gaming Blackwell at GTC, except for Samsung’s GDDR7 memory, which should come with the new series. Samsung is gearing up for the release of next-gen gaming cards, with plans to supply memory for the upcoming RTX 50 series...

Just found, SK Hynix is joining in as well. I do not recall the last time a video card came with their IC's. last time i recall seeing Hynix IC's was on DDR2/DDR3 ram.

its heating up!

*edit*
i had to go read up a about "PAM3", dude, i swear someone read one of my old posts. well since all the old ones have been purged now. I said something to the effect of what PAM3 is doing but i said it would be 4bits vs 3bits. All it takes is time and engineering to get there. Does this mean "PAM4" is going to be in GDDR8 spec?

They are clearly trying to be leaders in this market.I wonder how Micron will react to these achievements of Samsung. Will they have something equally impressive in the near future?

Samsung can show whatever they want, but afaik, Micron is leading because they have already signed deals with Nvidia for the next-gen cards and some other brands for mass delivery of new chips. They also delivered most memory chips for the RTX3000/4000.
GDDR7 is the same as any previous memory. I mean, it's JEDEC specs, so no matter what brand delivers it, it needs the same specs. The only difference is that one brand can have higher frequency chips than others. As long as AMD/Nvidia specifies something, then it doesn't matter if others have faster chips or not. It doesn't matter as AMD/Nvidia partners will release graphics cards that are close to the reference specs. Who cares if someone has 2x faster memory when it won't be used anywhere in the upcoming generations, and later the competition will catch up.
