No matter what you’d do, you probably wouldn’t launch a new flagship by burying the announcement at the bottom of a blog post focused on a new GPU driver, three days after the card launched. And you certainly wouldn’t launch the card a week after the biggest tech event of the year without any day one reviews.
That’s what Nvidia did with the RTX 3080 12GB, and people are justifiably confused. It’s a graphics card that doesn’t need to exist with Nvidia’s current offerings, and it shows a worrying trend for where GPU prices may be headed in 2022. The 12GB RTX 3080 is a bastardized version of one of the best graphics cards you can buy — and that’s a shame.
Price and availability
Our reviews normally start with a discussion of design, specs, and performance, but don’t forget: It’s impossible to talk about a graphics card apart from price. Performance doesn’t matter on its own. Performance based on the price is what makes the difference.
And in this case, it’s the most crucial element of the 12GB version of the RTX 3080.
Nvidia never set a list price for this graphics card, and although list price doesn’t mean much, it still serves as a point of comparative value. Even in the midst of the GPU shortage where prices ebb and flow, cards still stack in the way the list prices suggest — the RTX 3080 costs more than the RTX 3070, and so on.
So, what is the price of the 12GB RTX 3080? On the low end, it’s about $1,249 — $50 more than the RTX 3080 Ti. The EVGA XC3 Ultra version, for example, is listed at that price. That’s $40 more expensive than the RTX 3080 Ti version of the same model and $440 more expensive than the 10GB version. I’m not comparing high-end cards, either. These are EVGA’s most basic versions.
You’ll pay an inflated price no matter where you get your card.
Up the stack, the Asus ROG Strix version is $1,600, which is $400 more expensive than the 10GB ROG Strix model. It’s cheaper than the RTX 3080 Ti version, technically, but that’s only because that card is out of stock and Asus doesn’t offer list prices on its website.
Even with inflated prices, you’re looking at a much more expensive graphics card. On eBay, the 12GB model is selling for about $300 more than the 10GB one, which is actually closer than the prices listed at retailers. The prices at retailers and on the secondhand market are closer now, sure, but that just means you’ll pay an inflated price no matter where you get your card.
There are a number of speculative reasons why the 12GB RTX 3080 is so expensive, but it boils down to this: The 12GB RTX 3080 will continue to sell for scalper prices once the market calms down. I’m not against Nvidia or board partners profiting off of their products, but I am against releasing a marginal upgrade to a GPU for a significantly higher price when most people still can’t even buy the base model.
Design
If it isn’t already clear, I’m not a fan of the 12GB RTX 3080. I have to give credit where it’s due, though, and that credit goes to MSI.
MSI was kind enough to send me a 12GB RTX 3080 Suprim X, which is great considering Nvidia doesn’t have a Founders Edition model of the 12GB RTX 3080. Regardless of what Nvidia is up to with this card, the Suprim X remains a wonderful design.
It’s technically a dual-slot card in that it only takes up two slots on the back of your machine, but the extra cooler height almost takes up enough space to occupy a third. As with other Suprim X models, this one includes a dual BIOS switch to toggle between Silent and Gaming modes, but even with the Gaming mode set, the card was never loud enough to become a problem.
Despite the silicon underneath, MSI has created an excellent graphics card.
Similarly, it comes factory overclocked with a 180MHz bump over Nvidia’s official spec, as well as a 50W boost on the power. To help with the increased power draw, the card uses three 8-pin connectors for power. To help with the massive cooler size, MSI includes a GPU support bracket in the box.
Despite what I think about the silicon underneath, MSI has created an excellent graphics card here. I particularly like the RGB MSI shield on the backplate, which accompanies an RGB strip running the length of the card.
Even in 2022, graphics card makers design cards that look great when viewed from the front. The Suprim X looks great from the front, but MSI went through the effort to make it look great while it’s installed in your computer. This might be the first time I like the backplate design more than the cooler.
All of this is to say that MSI made a great graphics card, but Nvidia made a mediocre GPU. The Suprim X makes the most of a bad situation, and if you find yourself able to choose between 12GB RTX 3080 models, this should be the one you reach for.
Specs
The 12GB RTX 3080 is just an RTX 3080 with 2GB more video memory, at least on the surface. The extra VRAM is the most striking change, but there’s a little more going on with the specs, especially compared to the RTX 3080 Ti.
| RTX 3080 12GB | RTX 3080 10GB | RTX 3080 Ti | |
| CUDA cores | 8,960 | 8,704 | 10,240 |
| Boost clock | 1.71GHz | 1.71GHz | 1.67MHz |
| Memory | 12GB GDDR6X | 10GB GDDR6X | 12GB GDDR6X |
| Memory bus | 384-bit | 320-bit | 384-bit |
| Effective bandwidth | 912.4GB/s | 760.3GB/s | 912.4GB/s |
| Tensor cores | 280 | 272 | 320 |
| RT cores | 70 | 68 | 80 |
| Power draw | 350W | 320W | 350W |
This is almost an RTX 3080 Ti, but with a big emphasis on “almost.” Over the 10GB RTX 3080, the 12GB model bumps up the memory bus to 384-bit and the power draw to 350W — both specs of the RTX 3080 Ti. It also has a slightly lower base clock speed, though that makes no difference in gaming when the boost clock is almost always active.
The key difference is that the 12GB RTX 3080 comes with a 3% bump in core count over the 10GB model, which is significantly lower than the RTX 3080 Ti. Here’s how to think about the card: It’s an RTX 3080 Ti, but with the core count of an RTX 3080.
It’s clear that the 12GB RTX 3080 doesn’t need to exist.
You should think about it as an RTX 3080 Ti, too. The 2GB bump in VRAM may seem insignificant, but when paired with the larger 384-bit memory bus, the 12GB model has much higher memory bandwidth: 912GB/s compared to 760GB/s on the 10GB model.
Even before getting to performance data, it’s clear that this is a graphics card that doesn’t need to exist. It doesn’t meet a need that’s not already met by the base or Ti model, and it illustrates a breaking point of granularity in Nvidia’s lineup where the minute differences between models become irrelevant.
Of course, the first question you ask about a new graphics card is: “What are the specs?” In the case of the 12GB RTX 3080, where specs matter more than they do with most other GPU releases, the specs don’t paint a clear picture. They’re insignificant in some areas and not practical in others. The only way to know what the 12GB RTX 3080 is trying to do is to see it perform in action.
Gaming
An extra 2GB of memory doesn’t matter for gaming — or at least, that’s what you’ll hear ad nauseum in comments sections and forums around the internet. It’s true that video memory doesn’t play a big role in performance past a certain point, but the increased memory bandwidth is relevant.
I ran all of my tests with 32GB of memory, an Intel Core i9-10900K, and the latest version of Windows 10. My comparison GPUs are Founders Edition cards, so I downclocked the Suprim X and limited the power to meet Nvidia’s spec. You can expect higher average performance with this particular card. Here are my results at 4K with the highest graphical preset.
| 12GB RTX 3080 | 10GB RTX 3080 | RTX 3080 Ti | RTX 3090 | |
| 3DMark Time Spy | 17,071 | 16,108 | 17,634 | 18,341 |
| Red Dead Redemption 2 | 65 fps | N/A | 72 fps | 77 fps |
| Fortnite | 76 fps | 95 fps | 93 fps | 78 fps |
| Assassin’s Creed Valhalla | 61 fps | 62 fps | 55 fps | 63 fps |
| Battlefield V | 103 fps | 100 fps | 104 fps | 121 fps |
| Civilization VI | 212 fps | 255 fps | 259 fps | N/A |
There’s nothing too surprising from my results. In 3DMark Time Spy, the 12GB RTX 3080 is about 3% slower than the RTX 3080 Ti and about 6% faster than the 10GB model. Battlefield 5illustrates this point further, with only a single frame separating the 12GB RTX 3080 and RTX 3080 Ti.
Fortniteonly brought a two-frame difference between the 12GB RTX 3080 and the RTX 3090. My middle two benchmarks were run on a different patch of the game, so you shouldn’t compare those results with the others. The difference between the 12GB RTX 3080 and RTX 3090 paints the picture clearly: The 12GB RTX 3080 isn’t offering a big performance benefit.
Red Dead Redemption 2andCivilization VIare redundant. The trend is clear here. Intentionally handicapped or free to run at full speed, the 12GB RTX 3080 is a slight upgrade over the 10GB model and sits below the RTX 3080 Ti. The RTX 3080 Ti was already a marginal upgrade over the base model; this 12GB variant just splits the difference.
Content creation
I hoped the extra bandwidth of the 12GB RTX 3080 would provide an uplift in content creation performance, but that wasn’t the case. Even without limiting the power or clock speed, the card functioned around the same level as the 10GB model and a decent margin away from the RTX 3080 Ti.
| 12GB RTX 3080 | 10GB RTX 3080 | RTX 3080 Ti | RTX 3090 | |
| PugetBench for Premiere Pro | 799 | 821 | 855 | 855 |
| Blender BMW (lower is better) | 19 seconds | 23 seconds | 19 seconds | 17 seconds |
| Blender Classroom (lower is better) | 100 seconds | 71 seconds | 56 seconds | 79 seconds |
| Blender Koro (lower is better) | 65 seconds | 75 seconds | 63 seconds | 57 seconds |
The chart above shows diminishing returns in action. There are only minor differences between the 10GB RTX 3080 and the RTX 3090, with the latter only offering an advantage in dedicated workstations. On the whole, the 12GB RTX 3080 falls in between the 10GB model and the RTX 3080 Ti like it should, but the results are so tight here that it hardly matters.
For content creation, it’s about what you need the graphics card for. There isn’t enough of an advantage to justify the 12GB RTX 3080 over the 10GB version, even if all you’re concerned with is content creation. Given the prices, which I’ll dig into next, the RTX 3080 Ti is the better pick overall, and the RTX 3090 takes the crown.
Our take
The 12GB RTX 3080 doesn’t need to exist. Even the RTX 3080 Ti was a disappointment considering how much more expensive it was than the RTX 3080, and this 12GB variant just splits the difference between those two. It’s unnecessary product segmentation that only serves the purpose of increasing the base price of the RTX 3080.
Nvidia says that the 10GB model will live on, but I find that hard to believe. There’s no reason to pick the 12GB RTX 3080 over the 10GB version or the RTX 3080 Ti, and Nvidia is aware of that. There’s a reason we didn’t have many day one reviews or a public launch like we did with the RTX 3050 and RTX 3090 Ti.
With the GPU shortage how it is, you should buy almost any graphics card you can get for decent price. There’s a chance that’s the 12GB RTX 3080, and in that case, the card is a great performer. If the price trends I’m seeing continue, though, the 12GB RTX 3080 will remain a bad buy compared to the 10GB and Ti models, even at inflated scalper prices.
Are there any alternatives?
Yes. The 10GB RTX 3080 and RTX 3080 Ti are so close to this model that they serve as viable alternatives. On the AMD side, the RX 6800 XT is the most direct competitor, though it struggles with ray tracing.
How long will it last?
Although the 12GB RTX 3080 is a disappointing graphics card, it’s not a bad one. Like the 10GB base model, this one will last you at least the next few years at 4K and likely several years at lower resolutions.
Should you buy it?
No. The 12GB RTX 3080 would be among the best graphics cards if the 10GB version and RTX 3080 Ti didn’t exist. They do, and they hit a much better balance between price and performance.
