Massive RTX 4000 info dump from prominent YouTuber reinforces incredible performance claims for Nvidia's next-gen GPUs
YouTuber and serial leaker Moore’s Law is Dead has revealed some new information and confirmed some old leaks about Nvidia’s upcoming RTX 4000 series GPUs codenamed “Lovelace”. In his video, MLID presents a detailed overview of the seemingly confirmed power draw numbers and memory speeds for Nvidia’s AD102 Lovelace chip.
According to MLID’s sources, Nvidia’s top-of-the-line AD102 GPU will be featured in the RTX 4090 and maybe the RTX 4080. AD102 was, at first, a 400 – 450 W chip with a target of 60 – 80% better performance than Nvidia’s current flagship Ampere cards. However, because AMD’s RDNA 3 GPUs are reportedly powerful enough to beat Nvidia’s Lovelace in rasterization performance, Nvidia allegedly increased the TDP target of AD102 from 400 – 450 W to 450 – 550 W. One of MLID’s sources even went as far as to say,”500 – 600 W is the current expectation.”
Moving on, MLID revealed that the memory controllers of the RTX 4000 series GPUs are quite a lot better than RTX 3000. Reportedly, Nvidia has designed the AD102 GPU to handle GDDR7 memory speeds. It may even support GDDR7 down the line. Per one MLID source, GDDR7 may not be ready to make it into Nvidia Lovelace for the launch but the company will use the fastest GDDR memory chips available.
According to the same source, Nvidia can even refresh the lineup and launch RTX 5000 series with GDDR7 sometime in 2023 to avenge a possible defeat from AMD’s RDNA 3.
When it comes to Lovelace’s performance, MLID expects ray tracing performance to get a 25 – 50% higher boost than the rasterization performance. While the leaker is confident in this number, he reiterates that it can change, and we can see a better or worse RT performance differential.
Aside from AD102, MLID estimates that the midrange RTX 4060 reportedly performs similar to an RTX 3080 in rasterization and like an RTX 3090 Ti in ray tracing. Upper midrange and higher-end cards like the RTX 4060 Ti and the RTX 4070 allegedly perform up to 30% better than an RTX 3090.
MLID expects Nvidia to hold a “paper launch” for the RTX 4000 GPUs by the end of Q3 2022.
