It’s always a bit of fun to speculate about the relative performance of high-end GPUs. There’s a new leak that suggests that AMD’s next-generation Navi 33 GPU, which is reputed to be used in the RX 7600 or 7700, could run out faster than the current flagship RX 6900 XT, with much lower power consumption.
The rumor comes from @greymon55 (by hardware times). This suggests that the Navi 33 GPU is likely to feature FP32 performance that surpasses the 6900 XT. FP32 is a floating point performance measure. It’s far from the only relevant measure of graphics card performance, but it’s a good sign that AMD has the foundation of a powerful architecture on its hands.
The source goes on to state that the first batch of GPUs are being tested internally by AMD, a process known as ‘bring up‘ which follows the initial tape-out chip. It is believed to be a monolithic array built on TSMC’s 6nm node. Greymon further believes that the GPU will end up consuming between 220 and 250W.
Again, we emphasize that this is just a rumor, but if AMD is able to beat the 6900 XT while maintaining similar power to a 6700 XT, that bodes well for performance per watt for next-gen mid-range GPUs.
As we head into 2022, we get closer and closer to the launch of next-gen GPUs. Rumors indicate that both ada lovelace and RDNA 3 cards can provide big performance boosts. Nor can we forget Intel with its Arc Alchemist cards.
It’s not all rosy though. Other rumors indicate that high-end cards may come with very steep TDPs and require new power supplies with 12 pin power connectors. Whatever the shape, performance levels, and power efficiency of next-gen cards, if we can afford them, it’s a step in the right direction!
