Excitement builds as new RTX 4090 specs emerge

It was just yesterday that a new rumor surfaced suggesting that Nvidia’s RTX 40 series launch would take place at the beginning of the third trimester. Kopite7kimi it has since shortened the release deadline to ‘mid-July’, which would put the release just a few weeks from now. But now the serial leaker goes further, causing a updated set of specs for the high-end RTX 4090, and they even give a performance estimate.

First, it’s important to note that these are rumored specs. But if launch is just a few weeks away, the final specs have certainly been set and the first batches of cards will be in production. So, let’s take a look at the latest potential specs provided by Kopite7kimi.

Shader count has decreased from previous leaks. 16,128 shader cores is still a dramatic increase over the RTX 3090 Ti, but this is not unexpected given the much higher transistor density provided by TSMC’s N4 process. It is expected to include 24GB of 21Gbps GDDR6X memory, the same amount and speed that the 3090 Ti comes with.

Perhaps the most interesting specification is the new 450W TDP. After all the talking and rumored 600W or more, this is very welcome news. This means that the current designs of the RTX 3090 Ti likely resemble their RTX 4090 counterparts. We were surprised at how quiet the fans of the Asus TUF RTX 3090 Ti were and if that TDP ends up being carried over to the RTX 4090 (and therefore certainly less than 450W for a 4080), I’m sure the RTX 40 cards will be manageable and be able to run at relatively cool temperatures without the need to resort to the fans screaming with banshee.

RTX 4090 RTX 3090 Ti
GPU AD102 GA102
CUDA cores 16,128 10,752
Memory 24GB GDDR6X at 21Gbps 24GB GDDR6X at 21Gbps
Energy consumption 450 W 450 W

Then there’s the performance estimation. Doubling the 3D performance of the RTX 3090 would be nothing short of spectacular. Again, this is just a rumor, but even 50% or more would be a very impressive generational lift, and it would mean that the Ada Lovelace SKUs can actually deliver improved performance per watt over their RTX 30 predecessors. This is not something I expected . If Nvidia can pull this off, it would be a dramatic shift in narrative.

There don’t seem to be any tech or trade fairs in mid-July, but that doesn’t mean anything. Nvidia is perfectly capable of hosting its own launch event, and in fact that means it can handle the news cycle, unlike a program like Computex where the stage is shared, so to speak. If Nvidia plans a launch event in July, we can expect to see teasers or a countdown in the days and weeks ahead. It’s worth keeping an eye out for Nvidia’s Computex keynote next week.

The other nugget of Kopite7kimi’s tweet is that they are disappointed with the RDNA 3. Whether this is relative as a result of the RTX 4090 2x performance claim or something with the RDNA 3 itself is unknown, but whether or not AMD would invent a hypothetical RX 7900 XT with 50% or more performance over a 6950 XT wouldn’t be enough if these latest Nvidia rumors were accurate.

It’s all getting closer folks. Start saving. We’re all very excited to see how the GPU battle unfolds.
