Nvidia Ada Lovelace GPUs Are Twice As Fast and Power Hungry

As many people still struggle to get their hands on one of Nvidia’s RTX 30-Series graphics cards, preparations for the next generation of GPUs are well underway. The next line of Nvidia graphics, code-named Ada Lovelace, is said to release in 2022.

According to rumors, the new cards may turn out to be twice as fast as the current generation, placing them firmly at the top of any list of the best graphics cards. The dramatic increase in performance comes at a price, though: Nvidia 40-Series graphics cards may also be twice as power-hungry as the current models.

The rumor comes from a well-known leaker on Twitter, @Greymon55, who has a long track record for revealing information about the upcoming releases of both Nvidia and AMD. Previous rumors about the upcoming Nvidia release also come from Greymon55 and Kopite7kimi. Put together, all the leaks are starting to form a fairly clear picture that shows us what to expect from Ada Lovelace GPUs.

According to various rumors, GeForce RTX 40-Series GPUs will run on the new AD102 chip, also referred to as ADA GPU. The new cards may offer a massive step-up in terms of the number of CUDA cores. Rumored to have 18,432 CUDA cores, Ada Lovelace GPUs will have almost twice as many as the current generation of Ampere cards.

According to Kopite7kimi, the new RTX GPUs will run on TSMC’s 5nm process node and might have an astounding clock speed of up to 2.2GHz. There may also be a serious jump in teraflops (TFLOPs). Nvidia’s top card, the RTX 3090, currently has 36 TFLOPs of FP32 compute power. Ada Lovelace cards are rumored to pack up to 81 TFLOPs, which is over twice as much as the RTX 3090.

Some users were wondering whether Nvidia will utilize a multi-chip module (MCM) architecture in Ada Lovelace. Nvidia’s upcoming Hopper GPU, made for data centers and working with AI, is supposed to release fairly soon, and it will feature MCM. However, it’s more likely that Nvidia will not use MCM in Ada Lovelace GPUs and will stick to the traditional design.

Although the cards are almost certain to be massive upgrades to the current generation, the power comes at a certain price. Nvidia’s current RTX 3090 is already a power-hungry card, and the rumored RTX 3090 Ti is said to have a TGP of 450W. This means that Ada Lovelace cards may have a TDP of up to 600W. Such high-power requirements will force the use of the best power supply units available.

No release date for Ada Lovelace GPUs has been confirmed yet, but all signs point to 2022. With the ongoing graphics card shortage, it’s possible that many users won’t get their hands on the new cards right away.

Nvidia RTX 40 Series GPUs Might Be Even More Power Hungry

A flurry of recent rumors suggests that Nvidia’s upcoming RTX 40-series graphics cards will be even more power-hungry than what’s currently available. Leakers peg the power consumption in the range of 400W to 500W for the flagship card, which is higher than even the obscenely powerful RTX 3090.

3DCenter, who has previously covered the roller coaster of GPU prices in Europe, nailed down multiple leakers claiming the card will use at least 400W of power. That’s certainly not out of the question, as the RTX 3090 already requires 350W of power. Assuming Nvidia wants to push even more power out of the upcoming range, a 400W+ power requirement could be possible.

Nvidia hasn’t announced anything about the RTX 40-series yet, so it’s likely that developers are still tweaking the final design. Kopite7kimi, one of the leakers who claimed a 400W+ power limit and is known for Nvidia leaks, said the upcoming range will be built on chipmaker TSMC’s 5nm node, breaking from the 8nm Samsung process Nvidia used on RTX 30-series graphics cards.

The next-generation architecture, tentatively named Lovelace, is rumored to arrive in late 2022 or early 2023. The rumor mill suggests that the graphics core powering the range will be capable of housing up to 18,432 CUDA cores, which is nearly 8,000 more than the RTX 3090.

AMD’s upcoming cards are rumored to require equally as much power. The RDNA 3 range is also rumored to consume between 400W and 500W of power with TSMC’s 5nm process. During a recent investors call, AMD CEO Lisa Su confirmed that 5nm is the goal and that the GPUs are on track for a 2022 launch.

Unlike Lovelace, RDNA 3 cards are rumored to use a multi-chip-module (MCM) GPU package. Essentially, the upcoming range is rumored to utilize multiple dies on the same package, unlike the RTX 40-series’ traditional monolithic design.

Nvidia is rumored to be working on its own MCM design, currently named Hopper. Originally, rumors pegged Hopper as the successor to the current Ampere range, though recent speculation suggests Nvidia is locked on delivering Lovelace sooner.

Both new generations are rumored to offer up to a 2.5x improvement over the current generation. As for where they’ll fall in relation to each other, it’s too soon to say.

As is the case with all early rumors and speculation, you shouldn’t take this information as law. We’re still far out from launch, so AMD and Nvidia are more than likely still finalizing the design and tweaking specs to meet their price, power, and performance targets.

Based on what we know so far, however, a higher power draw will likely be something PC builders need to deal with. Nvidia pushed past the 250W ceiling with the RTX 3080, RTX 3080 Ti, and RTX 3090, surpassing even the most powerful cards from the generations that proceeded them. It’s too soon to say for sure, but you might need to invest in a new power supply when these cards finally arrive.
