Nvidia’s RTX 4000 GPUs are getting closer to the elusive 3GHz mark

New rumors about the coming Nvidia GeForce RTX 4000 generation of cards is becoming more and more tempting. With intensely high clock speeds, the GPUs may be able to deliver unprecedented performance.

The RTX 4090, in particular, is likely to blow its predecessor out of the water, but that kind of power certainly comes at a price.

Today, well-known Twitter leaker Kopite7kimi once again delivers more information about the upcoming Nvidia GeForce RTX 40 series, also known as Ada Lovelace. While we’ve seen some of it from various sources before, there’s a new major piece of gossip that’s especially exciting, and that’s the clock frequency on the new flagship RTX 4090.

According to the leaker, the Nvidia GeForce RTX 4090 may have a base clock speed of 2235MHz that can be bumped up to 2520MHz. Even those speeds alone give him an edge over his older sibling, the RTX 3090 Ti, which provides 1670MHz and 1860MHz respectively. Of course, these speeds only apply to the Founders Edition, so modified versions of the card can and will beat the base version prepared by Nvidia itself.

Kopite7kimi also claims that the actual speed of the GPU may exceed the 2.5GHz limit. By overclocking the graphics card itself, even higher numbers can be achieved, and in this case kopite7kimi expects the RTX 4090 to be able to reach as much as 2.75GHz when boosted. As PCGamer points out that this could mean we could finally see an Nvidia GPU hit the 3GHz clock speed mark, or at least get closer to it than ever before.

There’s still the rumored RTX 4090 Ti to consider, and that will likely take performance to an even higher level. When the RTX 4090 Ti is released, it is rumored to have the full 18,432 CUDA cores, which is an upgrade from the RTX 4090’s 16,384. Unsurprisingly, this is almost guaranteed to result in an increase in power consumption. .

Of course, all that performance has to come from somewhere, and that brings us to a topic that’s been discussed many times in relation to next-gen Nvidia GPUs – the power consumption. This time, Kopite7kimi predicts a 450-watt TDP for Nvidia’s new flagship. We can safely expect that number to increase with modified versions of the card, which will probably bring the frequency even closer to 3GHz, but as a result they will also require an even more powerful power supply.

Thermals of such a GPU will also be a consideration. The graphics cards will likely be huge and generate a lot of heat, requiring an airy, large case with a lot of consideration for temperatures.

While the RTX 4090 will be a high-end GPU that many users aren’t planning to buy, it will be followed by the (hopefully more reasonably priced) RTX 4080 and RTX 4070, both of which have interesting specs. Especially the RTX 4080 will be one of the best graphics cards for gamers if it delivers the rumored specs at a decent price.

According to Kopite7kimi – and this is in line with several previous leaks – the RTX 4080 would ship with 10,240 CUDA cores. It is also said to deliver 16GB of 21Gbps GDDR6X memory over a 256-bit memory bus. The TDP is expected to be around 420 watts, which is strangely close to the RTX 4090. In terms of specifications, the GPU is very similar to the RTX 3090.

The RTX 4070 continues to look less exciting than its siblings. According to the previous rumors, it is rumored to have only 10 GB of memory over a 160-bit memory bus. However, Kopite7kimi also predicts that it will come with 7,168 CUDA cores and 18 Gbps GDDR6 memory. In a way, it’s a rather odd GPU, but it can still hold its own when priced competitively.

We’re getting closer to the rumored release dates for a lot of exciting PC hardware and for graphics cards it’s going to be a real battle. With AMD slated to launch RDNA 3 GPUs soon, and Nvidia getting Ada Lovelace poised to emulate AMD, the rumors will only get more juicy as we get closer to the real deal.
