![]() ![]() ![]() The RTX 3090 comes with an all-time high TDP for a single GPU of 350W (that doesn't count the A100, obviously), while the RTX 3080 has a 320W TDP. GeForce RTX 2080 Ti was a 250/260W part, and the Titan RTX was a 280W part. The V100 was a 300W part for the data center model, and the new Nvidia A100 pushes that to 400W. Nvidia is taking the middle route and offering even more performance at still higher power levels. While 7nm/8nm does allow for better efficiency at the same performance, it also allows for much higher performance at the same power. The consumer GPUs also increase in transistor counts while greatly reducing die sizes. That's a massive 156% increase in transistor count from the GV100, while the die size is only 1.3% larger. GA100 for example has 54 billion transistors and an 826mm square die size. Instead, Nvidia is taking all the extra transistors and efficiency and simply offering more, at least at the top of the product stack. With the shift from TSMC's 12nm FinFET node to TSMC N7 and Samsung 8N, many expected Ampere to deliver better performance at lower power levels. Of course, third party designs are free to deviate from Nvidia's designs. As an Nvidia video notes, "Whenever we talk about GPU performance, it all comes from the more power you can give and can dissipate, the more performance you can get." A reworked cooling solution, fans, and PCB (printed circuit board) are all part of improving the overall performance story of Nvidia's Ampere GPUs. Besides the underlying GPU architecture, Nvidia has revamped the core graphics card design, with a heavy focus on cooling and power. ![]()
