As you can see, the RTX 3090 and 4080 are very similar, which makes sense since they’re only a generation apart. However, there are some key differences, so let’s discuss them.

RTX 3090 vs. 4080: What’s the Difference?

In general, both the RTX 3090 and 4080 are top-of-the-line graphics cards that can deliver excellent performance in a wide variety of applications. However, there are a few key differences to be aware of.

One of these is the amount of memory: the RTX 3090 has almost 10 more gigs of memory, which can give it an advantage in tasks such as 4k or 8k gaming and heavy video editing. 

You should also remember that the RTX 3090 uses the slightly faster GDDR6X memory instead of GDDR6. However, this difference is pretty small and may only be noticeable in some situations where the card is tested to the extreme.

So, the RTX 3090 will probably perform slightly better for some particular uses. Only considering raw performance, the RTX 3090 and 4080 are very similar, despite their difference in clock speeds. Those only noticeably impact performance for most tasks when boosted to the max, as then the RTX 4080 has an advantage of almost 1000 MHz.

So, in most cases, the performance of these graphics cards will be almost identical, but they could both be bottlenecked by a comparatively less powerful CPU. Let’s get into the details.


When it comes to high-end graphics cards, the specs are what truly make each generation shine. So let’s take a look at how the RTX 3090 and the RTX 4080 compare in terms of core count, clock speed, and other specs.

Clock Speed and Cuda Cores

The RTX 3090 features 10496 CUDA cores, while the RTX 4080 has 9728 CUDA cores, making the RTX 3090 the clear winner in terms of core count, but not by that much. The RTX 3090 also has a base clock speed of 1395 MHz and a boost clock speed of 1695 MHz, while the RTX 4080 has a base clock speed of 2205MHz, and a boost speed of 2505MHz. This makes the RTX 4080 the winner in terms of clock speed.


The RTX 3090 uses GDDR6X memory, while the RTX 4080 uses GDDR6 memory. GDDR6X memory is faster and more efficient than GDDR6 memory, which means that the RTX 3090 will have an advantage when it comes to some intensive tasks like high-resolution gaming or heavy video editing. Additionally, the RTX 4080 only has 10GB of VRAM, whereas the RTX 3090 has a much bigger 24GB. The RTX 3090 is the clear winner.

TDP and Cooling

The RTX 3090 has a TDP of 350W, which is pretty high for a graphics card. To handle this power, it features —and frankly requires— a triple-slot, triple-fan cooling solution. On the other hand, The RTX 4080’s TDP is a lower 320W, but it also needs three fans and a similar build.

Pricing and Availability

The RTX 3090 and 4080 are both high-end models, so you should expect to pay a premium price. The RTX 3090 has a suggested retail price of $1,499, while the 4080 has a suggested retail price of $699.

Both graphics cards are highly demanded, so they can be challenging to find in stock. Some retailers may have small quantities available for pre-order, and demand may skyrocket with sales or discounts.

It’s also worth noting that the prices of graphics cards can fluctuate over time due to various factors, but in recent years cryptocurrency mining has disrupted the market, so you should check back regularly to see if more units become available.

Frequently Asked Questions

Which card consumes more power?

The RTX 3090 has a higher power draw than the RTX 4080. The max TDP of the RTX 3090 is 350W, and the max TDP of the RTX 4080 is 320w. While the RTX 4080 is more energy-efficient, the recommended size of your PSU doesn’t vary, so don’t worry too much about this point.

Which card is better for video editing?

In general, higher VRAM is better for video editing, as that’s a task that requires the graphics card to process a lot of information in high quality in a very short period. If you’re looking to edit 4k or 8k videos, the RTX 3090 will allow you to do so more efficiently.

Is the RTX 4080 more future proof than the RTX 3090?

This largely depends on what you intend to use your graphics card for. If you enjoy gaming or video editing at the highest resolutions and framerates, you’ll generally always need the best. For now, if you have to choose between the RTX 3090 and the RTX 4080, that’s probably the RTX 3090, as it has more VRAM. However, if you only care about framerates and don’t tend to play in 4k or 8k, the RTX 4080’s higher maximum clock speeds will serve you better in the long run.

When was the RTX 3090 released?

The Nvidia RTX 3090 was released in September 2020, making it over two years old.

When was the RTX 4080 released?

The RTX 4080 launched in November of 2022, so it’s the latest generation of GPUs released by Nvidia.
