NVIDIA is preparing to launch its next-gen RTX 40 series graphics cards next quarter. According to a well-reported source on the matter, Team Green is aiming for an early Q3 launch. Considering this timeline, you’d think that the reveal would come at Computex later this month. However, that’s not gonna happen, at least not in my opinion. (messinascatering) Jensen has personally announced every new generation of gaming and data center GPUs for as long as I can remember. Since he won’t be presenting at this year’s Computex, I just don’t see a major launch happening this or the next month. An August or September launch is much more likely.
The GeForce RTX 4090 is expected to more than double the performance of its predecessor using a combination of high core and boost clocks, faster memory, and architectural improvements. The AD102 die will feature 12 GPCs, a 70% and 50% increase over the RTX 3090/3090 Ti (GA102), and the GA100/H100, respectively. The overall FP32+INT32 ALU or core count per SM is rumored to grow by 50% over Ampere, resulting in a 33% boost in warp and thread counts. The ROP count per GPC too is slated to double while the L1 cache will be extended to 192KB (+50%). Finally, the L2 cache is set to get a massive upgrade, going from just 6MB on the RTX 3090/3090 Ti to 96MB on the RTX 4090/4090 Ti.

AMD’s Radeon RX 7700 XT/7900 XT launches have also been preponed. The RX 7700 XT featuring the Navi 33 die is now expected to launch in Q3 as well, followed by the Navi 31-based 7900 XT in early Q4.
