NVIDIA GeForce RTX 5080 SUPER Could Feature 24 GB Memory, Increased Power Limits

[btarunr]

Hot on the heels of rumored specs of the GeForce RTX 5070 SUPER and RTX 5070 Ti SUPER, rumored specs of the RTX 5080 SUPER emerged on VideoCardz. Apparently, NVIDIA will not tap into the larger "GB202" silicon to build the RTX 5080 SUPER despite maxing out the "GB203" silicon to build the current RTX 5080. It will take a slightly different approach, by giving the card additional memory and power limits. 24 Gbit GDDR7 memory chips are a distinct feature of RTX 50-series SUPER graphics cards, and much like the RTX 5070 Ti SUPER, the RTX 5080 SUPER will feature 24 GB of GDDR7 memory across a 256-bit wide memory bus.

NVIDIA could possibly use 30 Gbps memory speeds for this SKU to end up with at least the same kind of bandwidth as the regular RTX 5080, which is 960 GB/s. The other interesting aspect of the RTX 5080 SUPER is expected to be its increased TGP (total graphics power) value of 415 W, a 15% increase over the 360 W TGP of the RTX 5080. This increase in TGP will not just support the higher density memory chips, but also allow NVIDIA to increase GPU clock speeds. This will likely be necessary, given that NVIDIA has no headroom to increase shader counts on "GB203," and will need something to increase performance for games without heavy memory demands.

While the extra VRAM is much appreciated. We also want faster cards for cheaper.

Always something with Nvidia. You either get this or that. Why can't we have both?

I guess they don't really need to try very hard as AMD keeps shooting themselves in the foot as well.

 

[Chomiq]

Another meh refresh of 40 series.

Usually Super cards have some changes at least on hardware level so they will skip it for the first time ? Extra VRAM and more OC that's a comedy. The same gpu but with different name.

RTX 5080 already is very weak upgrade over original RTX 4080 only +15% boost @4k and now this shit appears on horizon.

Even RTX 4080 Super have some hardware changes more cores and a huge 1.3% boost over RTX 4080 @4k

I wonder if it displaces / replaces 5080 at same price. Surely that would make a few people happy, not the people that come to TPU to pay out on Nvidia of course, I mean actual buyers of their cards Wether they had 'enough' VRAM or not.

It's possible they use binned GPU's for this and can also attain a fairly easy 5-10%+ more performance over a standard 5080 if they actually want to, as virtually anyone overclocking a 5080 already can.

OK, the extra VRAM is nice... but this "Super" upgrade really is pointless.

Checking the latest RTX 5080 review, it looks like the RTX 5080, at 360W, is not power limited (less than a 1% performance increase after bumping the power limit 40W... and this after overclocking).
That means, the extra 55W power limit will be wasted, outside of extreme edge cases, and aside from the power increase due to denser memory chips.
Perhaps the extra VRAM will let you keep the card in service a little longer, but I would argue that it will run out of grunt in new games at 4k (where 16GB VRAM may start to be a limit in the near-/medium-term) well before the VRAM pool becomes an issue.

SO, while we can all happy with larger VRAM numbers, I really expect this card to perform 100% identically to the vanilla RTX 5080, while drawing more power, and very likely costing more as well.
Best case? Maybe they throw in a 'free' 5% overclock as stock on the new cards, and save everyone 5min of overclocking

1st time in Nvidia's history when Ti/Super model has compute units configured same way as base model.

RTX 5080 was supposed to have >16 GB VRAM to begin with.

 

[wolf]

RTX 5080 was supposed to have >16 GB VRAM to begin with.

Was it? I don't remember reading that from any tech press or nvidia themselves.

 

[LittleBro]

Was it? I don't remember reading that from any tech press or nvidia themselves.

It was supposed/estimated by users, given the performance uplift and of course the price uplift.
RTX 4070 Ti S had 16 GB of VRAM ... Just like RTX 5070 was supposed to have 16 GB VRAM.

 

[Krit]

1st time in Nvidia's history when Ti/Super model has compute units configured same way as base model.

All depends on consumers and it's definitely consumers fault not nvidia's fault. If consumers right now will allow this to happen then next time nvidia will downgrade RTX 60 Series even more.

Don't buy that piece of shit to get a better future performance/cost it's very simple.

Nice VRAM for those wanting to play with AI LLMs. Or running multiple 4K screens. Or NV vPC. Not a gamers upgrade, but a choice for those wanting multitalented cards at a mid-budget. I'd certainly choose the 24GB over the 16GB version even if it makes zero different to gaming FPS.

 

[Krit]

I'd certainly choose the 24GB over the 16GB version even if it makes zero different to gaming FPS.

That's a smart choice but what if it's costs 200$ more or at the end the same performance for more money.

Your what-if might be right on the mark in reality ;-)

 

[Rightness_1]

The performance of the 5080 is not good enough for the money they ask. Too much perf difference between the 5080 and the 5090 this gen. The 5080 should have come with 24GB in the first place, and is not worth investing in one unless you have money to burn. There is absolutely no longevity in a 16GB card in 2025, and as soon as the next gen consoles get released 16GB cards will not be enough.

6-8GB - Budget basement cards for 1080p and old and retro gaming with obsolete grade consumer AI
12GB - Low end 1440p gaming and very low end consumer grade AI
16GB - Midrange 1440p+ gaming and low end consumer grade AI
24GB - High end 4K gaming, with texture mods, mid range consumer grade AI
32GB - Enthusiast 4K+ gaming with texture mods, high end consumer grade AI
48-64GB - Enthusiast 5K+ gaming with texture mods and very high end consumer grade AI

16GB - Midrange gaming and low end AI
24GB - High end gaming, mid range AI
32GB - Enthusiast gaming, high end AI

For gaming zero difference at 1440p!!!

12GB, 10GB, 8GB will be to short now or little later.

16GB is enough but gpu itself is too weak..... 24gb will change nothing.

 

[b1k3rdude]

So still massivly slower than a 4090 -

5080 super

• Cores 10275
• TMUs 336
• ROPs 112
• Memory Size 24 GB
• Memory Type GDDR6X
• Bus Width 256 bit

Versus (4090)

• Cores 16384
• TMUs 512
• ROPs 176
• Memory Size 24 GB
• Memory Type GDDR6X
• Bus Width 384 bit

It needs to match or beat the 4090 at a lower power and lower price, otherwise whats the point.

You are wrong. Many games have mods that will not work on a 16GB card, and will make a 24GB suffer! OOTB gaming is not a challenge to a 16GB card, but many games are already struggling on a 12GB card at 4K.

Remember we are talking about this in mid 2025. A year from now and things will be different, and your $1600 card will be struggling. 16GB cards will be obsolete in 2 years time.

 

[Krit]

You are wrong.

Show me where 16GB of VRAM is not enough for 1440p gaming. Better GPU horsepower will be way, way better improvement over more VRAM and by far!!!

 

[Rightness_1]

Show me where 16GB of VRAM is not enought for 1440p gaming. Better GPU horsepower will be way, way better improvement over more VRAM and by far!!!

Cyberpunk with a 4K texture pack, 24GB is a challenge with that mod.. many, many other games with mods.

The 5080's performance effectively lands smack in the middle between the 4080 and 4090, making it a fancy 4080Ti, this (iirc) is the first -80 class GPU to not outperform the previous -90 halo model

I respectfully disagree with some of the scaling presented here : I have a 9070XT, I can crank 80% of my games to 1440p high/ultra and get 60 to triple digit FPS (depending on the title of course) it'll show TBP drawing 450W and raise my room's temperature by 4-8°C but hey, it'll crank out those frames ! (and yes, that's without FSR/FG, I barely tolerate upscaling, you'll never catch me dead using FG) so 16GB's range quality really depends on the GPU being used here : a 5060 16GB ? yeah, low-mid range 1440p, 5070Ti/9070XT ? absolutely high/ultra 1440p no issues

And all that while multistreaming AND playing VR, doesn't hit 16GB (only ever maxxed out around 14GB when really pushing it) so if 16GB really doesn't have longevity, something TERRIBLY WRONG has happened in the game industry.

So still massivly slower than a 4090 -

Point's to upsell you into buying a refresh or the twice-as-expensive halo model.
Wait, it's getting GD6X ? not GD7 ?

The vanilla 5080 is less than 15% slower than the 4090 in games, at half the price. The difference would be even smaller for the Super, if it has higher clocks and the higher power budget helps it.

NVIDIA GeForce RTX 5080 Founders Edition Review

The NVIDIA GeForce RTX 5080 is out now. Priced at $1000 it includes all the new GeForce RTX 50 features and offers good gaming performance. On the other hand, the gen-over-gen performance increase is smaller than expected, but NVIDIA didn't raise their pricing either.

www.techpowerup.com

The point is it'd be a similar performing card for a heck of a lot less money, now with no memory deficit if you want to use it for AI or whatever.

Where are you getting your information from, got links..?

The 5080 can't output a constant 60fps at 4k with RT, much less with mods

 

[N/A]

Almost 4090, it would be nice to just give it 12288 shaders this generation, and call this a 5070 Ti. If not 60 series.

That's why i'm saying that vram is enough but gpu itself it too weak.
