The Nvidia GTC 2022 Keynote occasion revealed the most recent batch of next-generation GPUs with the RTX 4000 Series, alongside the flagship Nvidia RTX 4090.

After a protracted wait, Nvidia has lastly introduced its next-generation graphic playing cards, with two releases: the Nvidia RTX 4090 and the Nvidia RTX 4080.

The newest GPUs include a brand new structure, often known as Ada Lovelace, and boast new options like DLSS 3 and Third-generation ray tracing.

But with a brand new batch of GPUs, it calls into query whether or not the final era continues to be price shopping for. If you’re desirous about seeing how this years flagship scores in opposition to the Nvidia RTX 3090, preserve studying, as we’re going to be breaking down the specs and efficiency claims.

The Nvidia RTX 3090 got here out in September 2020 with a beginning worth of £1399/$1499. Since it’s been out there for 2 years, it could possibly now be discovered on third-party websites, like Overclockers and eBay, for below £1000.

The RTX 4090 will probably be in the stores from 12 October 2022. The beginning worth for this GPU will probably be £1679/$1599, making it the most costly possibility out of the 2.


The Nvidia RTX 3090 makes use of Ampere structure, which has since been taken over by Lovelace. Ampere makes use of Samsung’s 8nm course of, with the RTX 3090 coming with 10,496 CUDA Cores. It additionally packs Micron’s 24GB GDDR6X video reminiscence.

It additionally requires a 12-pin PCle energy adaptor, with the GPU that includes a 350W energy draw.

The Nvidia RTX 4090 is available in only one configuration – in contrast to the Nvidia RTX 4080 – and has a CUDA Core depend of 16,384. We can see that it packs much more cores than its predecessor.

It’s constructed upon Lovelace structure, which options TSMC’s 4nm course of node. Nvidia was in a position to embody 76 billion transistors on the GPU, which is leaps and bounds greater than the 26 billion that characteristic on Ampere. Generally, extra transistors lead to quicker efficiency, because the information might be processed and transferred at a quicker charge.

The RTX 4090 comes with an enormous quantity of reminiscence at 24GB GDDR6X, placing it on par with the RTX 3090. This makes each of those graphic playing cards an awesome possibility if you happen to’re craving tons and many reminiscence.

However, the RTX 4090 requires much more energy than its predecessor, at 450W. This is likely one of the highest necessities for GPUs and requires 100W greater than the RTX 3090 – it could be time to improve your PSU.


Since we’ve not been in a position to assessment both of those graphic playing cards simply but, we are able to’t make any claims on which is extra highly effective proper now. Despite this, we are able to use the specs offered by Nvidia to get an concept of ​​which GPU has probably the most energy.

The newest flagship comes with much more CUDA Cores than its predecessor, which ought to lead to a quicker card. CUDA Cores are developed by Nvidia and they’re primarily the GPU equal of CPU cores, with extra cores permitting for extra information to be processed directly, which is good for graphically intensive video games.

Moreover, Lovelace appears to massively outpace Ampere by way of its efficiency. The smaller node and the massive quantity of transistors on the RTX 4090 imply that processing might be achieved quicker and extra effectively. The graph beneath reveals how a lot energy the Lovelace chip has in comparison with Ampere, additional suggesting that the newest GPU will be capable to massively outpace the RTX 3090.

Plus, the RTX 4090 comes with options which can be unique to the RTX 4000 Series. Two of crucial options are DLSS 3 and Third-generation ray tracing. The former will assist to push up frets charges to new heights, whereas the latter will allow even higher visuals with superior lighting results.

Until we get the chips in for testing, we can’t positively declare that the RTX 4090 gives improved energy efficiency over the RTX 3090. But, wanting on the up to date structure and the added CUDA Cores, it appears doubtless that the RTX 4090 will massively outpace the RTX 3090, and can most likely be the most suitable choice for anybody on the lookout for probably the most highly effective Nvidia graphics card.

Nvidia additionally claims the RTX 4090 is between 2x and 4x quicker than the RTX 3090 Ti, relying on the sport. If correct, this implies we are able to count on a sizeable efficiency improve for the RTX 4090 in comparison with the usual RTX 3090.

Make certain to go to Trusted Reviews quickly, as we hope to assessment these graphics playing cards over the approaching weeks and months to see which one gives the most effective efficiency.
