Nvidia’s RTX 4000 get new specs, and it’s not all good news

Nvidia’s upcoming Ada Lovelace graphics cards just got another set of rumors, and this time it’s a bit of a mixed bag.

While the news is good for one of the GPUs, the RTX 4070 actually got a cut when it comes to its specs – but the leaker says it won’t translate to a lower price.

And TBP, 450/420?/300W.

The information comes from kopite7kimi, a well-known name when it comes to PC hardware leaks, which has just unveiled an update to the specs of the RTX 4090, RTX 4080, and the RTX 4070. the specifications of the RTX 4090 and the RTX 4070, this is the first time we get predictions about the specifications of the RTX 4080.

Let’s start with the good news. If this rumor is true, the flagship RTX 4090 seems to have gotten a slight bump in core count. The previously reported number was 16,128 CUDA cores, and this has now increased to 16,384 cores, which translates into an upgrade from 126 streaming multiprocessors (SMs) to 128. As for the rest of the specs, they remain unchanged – current expectation is that the GPU gets 24 GB of GDDR6X memory via a 384-bit memory bus, as well as 21 Gbps of bandwidth.

The RTX 4090 includes the AD102 GPU, which can hit up to 144 SMs, but it seems unlikely that the RTX 4090 itself will ever reach such heights. The full version of the AD102 GPU will likely be found in an even better graphics card, be it a Titan or just an RTX 4090 Ti. It is also rumored to have monstrous power requirements. This time, kopite7kimi hasn’t revealed anything new about that map, and so far we’re still not sure if it even exists.

Moving on to the RTX 4080 with the AD103 GPU, it is said to come with 10,240 CUDA cores and 16 GB of memory. However, according to kopite7kimi, it would rely on GDDR6 memory rather than GDDR6X. Since the leaker predicts it to be 18 Gbps, that would actually make it slower than the RTX 3080 with its 19 Gbps memory. The number of cores is exactly the same as in the RTX 3080 Ti. So far, this GPU doesn’t sound very impressive, but it is said to come with a much larger L2 cache that could potentially offer an upgrade in its gaming performance over its predecessors.

When it comes to the RTX 4070, the GPU was rumored to have 12 GB of memory, but now kopite7kimi predicts only 10 GB over a 160-bit memory bus. It is said to offer 7,168 CUDA cores. While it’s certainly an upgrade over the RTX 3070, it may not quite be the generational leap some users are hoping for. It also wouldn’t get a price discount based on the reduction in specs, but we still don’t know the MSRP of this GPU, so it’s hard to judge its value.

Finally, the leaker has provided an update on the power requirements of the GPUs, which has certainly been much speculated in recent months. The predicted TBP for the RTX 4090 is 450 watts. It’s 420 watts for the RTX 4080 and 300 watts for the RTX 4070. Those numbers are a lot more conservative than the 600 watts (and higher) we’ve seen floating around.

What does all this mean for us – the end users of the upcoming RTX 40 series GPUs? Not too much yet. The specs are subject to change, and while kopite7kimi has a proven track record, they could also be wrong about the specs. As things stand, only the RTX 4090 appears to be a massive upgrade over its predecessor, while the other two are a much more modest change. It remains to be seen whether the pricing will reflect that or not.
