Alleged NVIDIA GeForce RTX 4090 Ti Founders Edition graphics card cooler pictured: Massive cooling design with huge heatsink, baseplate with GPU cover and memory

NVIDIA GeForce RTX 40 'Next-Gen Gaming' Graphics Cards Featuring Ada Lovelace GPUs Rumored For Early Q3 Launch

An alleged NVIDIA GeForce RTX 4090 Ti Founders Edition graphics card cooler has been leaked at Chiphell Forums. The cooler might give us a very first look at the updated Founders Edition design featured on next-gen Ada Lovelace GPUs.

NVIDIA GeForce RTX 4090 Ti Founders Edition graphics card cooler leaks: massive heatsink, larger baseplate for GPU/memory coverage

Recently, it was reported that NVIDIA’s GeForce RTX 40 series graphics card might launch as early as mid-July. This would suggest that we are only 2-3 months away from the first unveiling of the next-gen lineup based on the Ada Lovelace graphics architecture. Designed to be both powerful and power-hungry, the GeForce RTX 40 series lineup will require strong cooling and it looks like NVIDIA is giving a major upgrade to its existing Founders Edition design to meet the 450-600 watt specs.

NVIDIA finally launches the GeForce GTX 1630, the successor to the GT 1030: faster than the GTX 1050 Ti in terms of performance

The alleged ‘GeForce RTX 4090 Ti’ images show us three different segments of the FE cooler. First up we have the silver metal skeleton that wraps around the heatsink to give it a nice finish. Currently, the metal plate features a small logo of the card it is equipped on. The leaked plaque suggests it will likely continue on the flagship NVIDIA GeForce RTX 4090 Ti graphics card. But, one thing to point out is that the positioning of this logo has been changed from right to left. This part will only be visible on the bottom side of the graphics card, so it doesn’t really mean much where the label is positioned, but from a marketing perspective it might look weird.

The most interesting part is the radiator itself. It looks like NVIDIA will now use a larger baseplate which will not only cool the GPU but also the memory. Currently, NVIDIA uses thermal pads to dissipate heat from the memory dies to the heatsink of its RTX 3090 and 3090 Ti Founders Edition graphics cards.

This new heatsink layout will allow NVIDIA to cool at least twelve GDDR6X memory chips. It is likely that the same layout as the RTX 3090 Ti PCB will be used here with 4 GDDR6 chips on the right/left side, three on the top and 1 on the bottom. Since NVIDIA is expected to use higher spec GDDR6X chips on its next-gen cards, the extra cooling will be really essential for the AD102’s flagship components. There is also a large aluminum heatsink for the VRMs and two thermal pads for various components. The heatsinks on the sides also appear to have gone from 23 fins to 24 fins on the leaky design.

The overall design of the NVIDIA GeForce RTX 40 Founders Edition graphics cards is very similar to existing RTX 30 FE cards, but larger in general. (Image credits: Chiphell Forums)

We can also see heat pipes running from the main heatsink to the one at the back. Heat is going to be dissipated from the heatsink and out of the card thanks to a flow-through cooling design similar to that of existing FE cards. That said, the map seems to have 3 or even 4 slots this time around. It now remains to be seen if the RTX 4090 Ti cooler leaks much sooner or if it will be part of the lineup itself.

So far, there are only reports that the RTX 4090 will be released first with the RTX 4090 Ti coming later. This could be an early design for the “Ti” cooler or it’s likely that NVIDIA made a few prototype coolers and decided to go with the “non-Ti” variant first. Again, this is a purported photo of what could be the next-gen NVIDIA GeForce RTX 40 series cooling design, but we can’t say for sure, so treat it as a rumor for the moment.

Here’s everything we know about the NVIDIA GeForce RTX 4090 series graphics cards!

The AD102 “Ada Lovelace” GPU is expected to feature 144 SMs, a 71% increase over the existing GA102 GPU and house a massive 18,432 CUDA cores. The GeForce RTX 4090 GPU SKU is rumored to feature 16,128 CUDA cores, which is a 50% increase in core count over the RTX 3090, but 14% fewer cores than the full AD102 configuration that might be coming. later as RTX 4090 Ti. It’s the same situation this generation where the “Ti” variant of the 3090 got the full GA102 GPU and the non-Ti variant, although launched earlier, came with a reduced configuration.

In addition to SM count, Ada Lovelace GPUs will also feature increased L2 cache sizes. Starting with the AD102 GPU, the flagship is said to be equipped with up to 96MB of L2 cache, a crazy 16x increase from the 6MB L2 cache featured on GA102. This cache still isn’t as large as the Infinity Cache featured on AMD’s RDNA cards, but it’s still a huge leap forward for NVIDIA’s own graphics cards.

The NVIDIA GeForce RTX 4090 graphics card will also rock 24GB of GDDR6X memory clocked at 21Gbps on a 384-bit bus interface and delivering over 1.0TB/s bandwidth. The final details also tone down the overall TDP numbers to 450W, meaning the RTX 4090 can’t go crazy with the clocks the full-fat variant with a 600W would have to go with.

As we saw with the GeForce RTX 3090 Ti, there are some models that go beyond the 450W TBP (reference) and up to 516W (custom). The same goes for cards based on Ada Lovelace. And while it will take a lot of cooling, it looks like the AIBs are well on their way. We will likely see the use of more hybrid style GPU coolers rather than traditional air coolers once we get past the 600W TBP limit. This will mark a 33% increase in TBP over the RTX 3090 Ti. According to the latest rumors, NVIDIA is expected to announce its next-gen GeForce RTX 40 series by mid-July, meaning we’ll be receiving a new generation of cards in early Q3 2022.
