The 80 sequence has develop into the favored alternative, however will that keep the identical within the new era?
For one more cross-generational comparability, we take a look at the Nvidia RTX 4080 vs 3080. Though they share the identical mannequin there are fairly a number of variations.
Popping out in September 2020 it was the favored alternative. Though stricken by a scarcity with no inventory and excessive costs meant many couldn’t get one.
So it could be doubtless that the 4080 will come on the finish of 2022 and likewise succeed. Bringing the facility with out the top-end worth. So we now have a better take a look at what to anticipate.

For the brand new era, there’s an improve within the structure. The 40 sequence might be primarily based on the Ada structure as a substitute of Ampere.
With Nvidia optimizing and bettering the bottom structure you’ll be able to anticipate additional efficiency for a similar playing cards. Particularly with the change within the foundry course of between them.
Wanting on the chips, the RTX 3080 makes use of the GA102-200 GPU variant. Primarily based on Samsungs 8nm course of, it creates a dies 628mm² in measurement. Managing to carry 28.3 billion transistors.
While the RTX 4080 is rumored to characteristic an AD103-300 chip. Transferring again to TSMC it now might be constructed on a 5nm course of. So it can have a die measurement of 380mm² with an unknown transistor rely.
Though it’s a a lot smaller die measurement it’s potential it’d characteristic extra transistors with a extra compact measurement. Though it can additionally enhance the effectivity of the structure.
|RTX 4080||RTX 3080|
|GPU course of||TSMC N4||Samsung 8nm|
|Reminiscence||16GB GDDR6X||10/12GB GDDR6X|
|Reminiscence clock||21 Gbps||19 Gbps|
|Bandwidth||676 GB/s||760.3 GB/s/912.4 GB/s|
For the brand new card, we solely have the rumored specs to go off. So these are more likely to change additional down the road nearer to launch however we’ll replace it with time.
However for now, it may give us a way of what to anticipate. With a deep dive into what every part is accountable for and what they do.
CUDA cores are Nvidia’s parallel processor structure. It permits for extra environment friendly processing of graphics to carry to your display.
It’s the Compute Unified Gadget Structure and is a well-established system. With every era additional bettering how properly they work.
So though we are able to examine the numbers on the playing cards, they might not work the identical. And the ultimate specification might change earlier than the discharge of the cardboard.
The 3080 holds 8,704 CUDA cores inside its chip. While for now the RTX 4080 is claimed to sport 9,728 cores.
Subsequently there is a rise of round 12% within the cores. With an anticipated effectivity enchancment too, there’s ought to be a superb enchancment within the efficiency.
Though the efficiency per watt is what might matter within the next-gen. As there are some hungry playing cards anticipated to be popping out.
The video random entry reminiscence is there for a body buffer and pixel retailer. It permits a smoother expertise with higher framerate and latency.
It’s particularly helpful for bigger resolutions. As they’ve increased pixel counts to refill many gigabytes. And requiring increased speeds to maneuver that knowledge.
For the RTX 4080 vs 3080 comparisons, we see a possible enhance within the VRAM. With 16GB of GDDR6X up from 10/12GB of GDDR6X reminiscence.
Together with the capability, the clock can be growing. Up by 2 Gbps to 21 Gbps with the newer reminiscence chips.
Nonetheless, the reminiscence bus is supposedly lowering. Right down to 256-bit from 320/384-bit. This decreases the bandwidth to 676 GB/s, beneath what the present one provides.
Though it’s a lower it doesn’t instantly imply decrease efficiency. Because it won’t have utilized it beforehand whereas saving prices.
Thermal design energy is the entire quantity of power the GPU will eat at full utilization. With extra power-hungry playing cards working up your power invoice.
This energy can be transformed to thermal power. Which then is given off into your rig and room so it may be a consideration in your heating in Winter but additionally Summer season.
Between these two playing cards, there’s a large enhance in power consumption. With the 4080 supposedly rated at 420W. While the 3080 10GB began at 320W and the 12GB model at 350W.
RTX 4080 vs 3080 efficiency
There aren’t any official benchmarks but for the 4080. However there’s some preliminary 3DMark Time Spy Excessive knowledge we are able to take a look at.
The utility is helpful for evaluating the graphics scores. Though the ultimate rating might range with drivers and closing specs.
From rumors, we see the brand new card can attain a 15,000 graphics rating within the software program. Though they don’t seem to be closing so it may be exhausting to place them up in opposition to one another.
However as a baseline, we discover the 3080 averaging 8,046 on TSE. While the 12GB variant achieves a mean of 8,588.
If the rating holds up that’s an enchancment of 75%-88%. So there’s a whole lot of efficiency achieve however at the price of energy.
When taking a look at how a lot it can price you to purchase the brand new card there isn’t lots to go on. Value is a risky spec that may doubtless change proper till launch.
However there’s some foundation to go on. The 3080 got here out with an MSRP of $699USD/£649. Which then informally elevated to $799/£749 with the 12GB model.
So trying again on the pattern we anticipate a baseline of the present card with a possible enhance. So it can doubtless be within the vary of $699-850USD/£649-800.
Which is more likely to enhance over rising prices and inflation. However the enchancment in efficiency that’s anticipated might make it higher off and value the additional.

Is the 4080 value it over the 3080?
Wanting on the RTX 4080 vs 3080 is at present not sure. With no particular specs and benchmarks, there’s a whole lot of hypothesis.
However from the leaks and rumors, we do anticipate an enormous enhance in efficiency and TDP is a probable huge change.
Nonetheless, this might be at a value so now we have to see whether it is comparatively good. Seemingly pushing the 80 playing cards up additional in direction of high-end decisions.
RTX 4080 vs 3080 FAQs
How a lot better is 4080 than 3080?
If the Time Spy Excessive benchmarks are correct, the 4080 might be 75-88% higher than the 3080 10/12GB. However this isn’t closing and will change up till the cardboard is launched with correct benchmarks.
Is the 3080 nonetheless good?
Sure, the 3080 continues to be a robust and succesful card. Simply because one other card has come to interchange it doesn’t make the outdated card futile. And even enables you to purchase the outdated one for a deal if not battered. It could nonetheless obtain all the pieces chances are you’ll want right now.
How a lot quicker is 4080 than 3080?
When it comes to reminiscence clock speeds, the 4080 is claimed to be at 21 Gbps, two Gbps or 10% greater than the 3080.
When it comes to clock fee, there isn’t a particular reply but, however it’s more likely to enhance considerably. With it doubtlessly growing pace by 40-60%.
