Nvidia GeForce RTX 4090: two minute review

Well, the Nvidia GeForce RTX 4090 is finally here, and there's no question that it delivers on many of the lofty promises made by Nvidia ahead of its launch, delivering stunning gen-on-gen performance improvement that is more akin to a revolution than an advance. 

That said, you won't find four times performance increases here, and only in some instances will you see a 2x increase in performance over the Nvidia GeForce RTX 3090, much less the Nvidia GeForce RTX 3090 Ti, but a 50% to 70% increase in synthetic and gaming performance should be expected across the board with very rare exceptions where the GPU runs too far ahead of the CPU.

On the creative side of things, this card was made to render, completely lapping the RTX 3090 in Blender Cycles performance, which makes this the best graphics card for creatives on the market, period, hands down.

On the gaming side, this is the first graphics card to deliver fully native 4K ray-traced gaming performance at a very playable framerate, without the need for DLSS, showing the maturity of Nvidia's third-generation ray tracing cores.

Even more incredible, Nvidia's new DLSS 3 shows even more promise, delivering substantially faster framerates over the already revolutionary DLSS 2.0. And while we did not test DLSS 3 as extensively as we did the RTX 4090's native hardware (for reasons we'll explain in a bit), from what we've seen, Nvidia's new tech is probably an even more important advance than anything having to do with the hardware.

On trhe downside, the card does require even more power than its predecessor, and when paired with something like the Intel Core i9-12900K, you're going to be pulling close to 700W of power between these two components alone. Worse still, this additional power draw requires some very strategic cable management to practically use, and for a lot of builders, this is going to be a hard card to show off in a case with a bundle of PCIe cables in the way.

The price has also increased over its predecessor, though given its incredible performance and the price of the previous graphics card champ, the RTX 3090 Ti, the RTX 4090 offers for more performance for the price than any other card on the market other than the Nvidia GeForce RTX 3080 and Nvidia GeForce RTX 3080 Ti. So even though the Nvidia RTX 4090 is a very expensive card, what you are getting for the price makes it a very compelling value proposition if you can afford it.

In the end, the Nvidia GeForce RTX 4090 is definitely an enthusiast graphics card in terms of price and performance, since the level of power on offer here is really overkill for the vast majority of people who will even consider buying it. That said, if you are that enthusiast – or if you are a creative or a researcher who can actually demonstrate a need for this much power – there's isn't much else to say but to buy this card. 

It is more powerful than many of us ever thought it could be, and while I'd definitely argue that the Nvidia GeForce RTX 4070 Ti or AMD Radeon RX 7900 XTX is the better purchase for gamers given their price, the RTX 4090 was always going to be a card for the early adopters out there, as well as creatives who are out to spend the company's money, not their own, and the RTX 4090 will give you everything you could want in an enthusiast graphics card.

Nvidia GeForce RTX 4090: Price & availability

  • How much is it? MSRP listed at $1,599 (about £1,359, AU$2,300)
  • When is it out? It is available October 12, 2022.
  • Where can you get it? Available in the US, UK, and Australia.

The Nvidia GeForce RTX 4090 goes on sale worldwide on October 12, 2022, with an MSRP of $1,599 in the US (about £1,359/AU$2,300).

This is $100 more than the MSRP of the RTX 3090 when it was released in September 2020, but is also about $400 less than the MSRP of the RTX 3090 Ti, though the latter has come down considerably in price since the RTX 4090 was announced.

And while this is unquestionably expensive, this card is meant more as a creative professional's graphics card than it is for the average consumer, occupying the prosumer gray area between the best gaming PC and a Pixar-workstation.

Of course, third-party versions of the RTX 4090 are going to cost even more, and demand for this card is likely to drive up the price quite a bit at launch, but with the crash of the cryptobubble, we don't think we'll see quite the run-up in prices that we saw with the last generation of graphics cards.

Finally, one thing to note is that while this is an expensive graphics card, its performance is so far out ahead of similarly priced cards, that it offers a much better price to performance value than just about any other card out there, and it is far ahead of its immediate predecessors in this regard. Honestly, we don't really see this kind of price-to-performance ratio outside of the best cheap graphics cards, so this was definitely one of the biggest surprises coming out of our testing.

Ray tracing cores: 128
Power draw (TGP): 450W
Base clock: 2,235 MHz

Power connector: 1 x 16-pin

The Nvidia GeForce RTX 4090 features some major generational improvements on the hardware front, courtesy of the new Nvidia Lovelace architecture. For one, the AD102 GPU uses TSMC's 4nm node rather the Samsung 8nm node used by the Nvidia Ampere GeForce cards.

The die size is 608mm², so a little bit smaller than the 628mm² die in the GA102 GPU in the RTX 3090, and thanks to the TSMC node, Nvidia was able to cram 76.3 billion transistors onto the AD102 die, a 169% increase in transistor count over the GA102's 28.3 billion.

The clock speeds have also see a substantial jump, with the RTX 4090's base clock running at a speedy 2,235 MHz, compared to the RTX 3090's 1,395 MHz. It's boost clock also gets a commesurate jump up to 2,520 MHz from 1,695 MHz. 

It's memory clock is also slightly faster at 1,325 MHz, up from 1,219 MHz, giving the RTX 4090 a faster effective memory speed of 21.2 Gbps versus the RTX 3090's 19.5 Gbps. This lets the RTX 4090 get more out of the same 24GB GDDR6X VRAM as the RTX 3090.

When it comes to the number of cores, the RTX 4090 packs in 56% more streaming multiprocessors than the RTX 3090, 128 to 82, which translates into nearly 6,000 more CUDA cores as the RTX 3090 (16,384 to 10,496). That also means that the RTX 4090 packs in 46 additional ray tracing cores and an additional 184 Tensor cores, and next-gen cores at that, so they are even better at ray tracing and vectorized computations than its predecessor.

This is immediately apparent when cranking up ray tracing to the max on games like Cyberpunk 2077, and especially when running DLSS 3, which makes the jump to full-frame rendering rather than just the pixel rendering done by earlier iterations of DLSS.

Nvidia GeForce RTX 4090: design

  • Yeah, that 16-pin connector is a pain to work with
  • A little bit thicker, but a little shorter, than the RTX 3090

The Nvidia GeForce RTX 4090 Founders Edition looks very much like its predecessor, though there are some subtle and not-so-subtle differences. First off, this is a heavier card for sure, so don't be so surprised that we need to start adding support brackets to our PC builds. It might have been optional in the last generation, but it is absolutely a necessity with the Nvidia RTX 4090.

The Founders Edition does not come with one, but third-party cards will likely include them and manufacturers are already starting to sell them separately so we would definitely suggest you pick one up.

Otherwise, the dimensions of the RTX 4090 around that much different than the RTX 3090. It's a bit thicker than the RTX 3090, but it's a bit shorter as well, so if your case can fit an RTX 3090 FE it will most likely fit an RTX 4090 FE.

The fans on either side of the card help pull air through the heatsink to cool off the GPU and these work reasonably well, considering the additional power being pulled into the GPU.

Speaking of power, the RTX 4090 introduces us to a new 16-pin connector that requires four 8-pin connectors plugged into an adaptor to power the card. Considering the card's 450W TDP, this shouldn't be surprising, but actually trying to work with this kind of adapter in your case is probably going to be a nightmare. We definitely suggest that you look into the new PSU's coming onto the market that support this new connector without needing to resort to an adapter. If you're spending this much money on a new graphics card, you might as well go hog and make your life – and cable management – a bit easier.

Nvidia GeForce RTX 4090: performance

  • Unassisted native 4K ray-traced gaming is finally here
  • Creatives will love this card

So here we are, the section that really matters in this review. In the lead up to the Nvidia GeForce RTX 4090 announcement, we heard rumors of 2x performance increases, and those rumors were either not too far off or were actually on the mark, depending on the workload in question.

Across our synthetic benchmark tests, the Nvidia RTX 4090 produced eye-brow raising results from the jump, especially on more modern and advanced benchmarks like 3DMark Port Royal and Time Spy Extreme, occasionally fully lapping the RTX 3090 and running well ahead of the RTX 3090 Ti pretty much across the board.

This trend continues on to the GPU heavy creative benchmarks, with the Nvidia RTX 4090's Blender performance being especially noteable for more than doubling the RTX 3090 Ti's performance on two out of three tests, and blowing out any other competing 4K graphics card in Cycles rendering.

On Premiere Pro, the RTX 4090 scores noticeably higher than the RTX 3090 Ti, but the difference isn't nearly as dramatic since PugetBench for Premiere Pro measures full system performance rather than just isolating the GPU, and Adobe Photoshop is a heavily raterized workload, which is something that AMD has an advantage in over the past couple of generations, which is something we see pretty clearly in our tests. 

Gaming is obviously going to see some of the biggest jumps in performance with the RTX 4090, and our tests bear that out. Most gaming benchmarks show roughly 90% to 100% improved framerates with the RTX 4090 over the RTX 3090, and roughly 55% to 75% better performance than the Nvidia RTX 3090 Ti.

These numbers are likely to jump even higher when you factor in DLSS 3. DLSS 3 isn't available in any commercially available games yet, but we were able to test DLSS 3 on a couple of special builds games that will be available shortly after the release of the RTX 4090. A few of these games had in-game benchmarks that we could use to test the performance of DLSS 3 using Nvidia's FrameView tool and the results showed two to three times better performance on some games than we got using current builds on Steam with DLSS 2.0.

Since we were using special builds and Nvidia-provided tools, we can't necessarily declare these results representative until we are able to test them out on independent benchmarks, but just eyeballing the benchmark demos themselves we see an obvious improvement to the framerates of DLSS 3 over DLSS 2.0. 

Whether the two to three times better performance will hold up after its official release remains to be seen, but as much as DLSS 2.0 revolutionized the performance of the best PC games, DLSS 3 looks to be just as game-changing once it gets picked up by developers across the PC gaming scene. Needless to say, AMD needs to step up its upscaling game if it ever hopes to compete on the high-end 4K scene.

Now, there is a real question about whether most gamers will ever need anything coming close to this kind of performance, and there is such a thing as diminishing returns. Some might find that the native 4K ray tracing is neat, but kind of redundant since DLSS can get you roughly the same experience with an RTX 3090 or even an RTX 3080 Ti, but that's a judgment that individual consumers are going to have to make. 

Personally, I think this card is at least approaching the point of overkill, but there's no doubt that it overkills those frame rates like no other.
