(The GeForce RTX 3090 is about ready to make the 3080 FE look puny, though, with its massive three-slot cooler.) It’s also about 2cm longer than the previous generation cards and uses the typical two-slot width. It’s actually about 100g heavier than the previous RTX 2080 design, and as far as I’m aware, it’s the heaviest single-GPU card Nvidia has ever created. Personally, I think the new card looks quite nice, and it feels very solid in the hand. There’s no RGB bling if that’s your thing, and the only lighting consists of a white GeForce RTX logo on the top of the card with subtle lighting around the ‘X’ on both sides of the card (but only half of the ‘X’ is lit up on the side with the “RTX 3080” logo). We’ll see the fruits of the design later.Īesthetics are highly subjective, and we’ve heard plenty of people like the new design, while others think it looks boring. Nvidia says the new design delivers substantial improvements in cooling efficiency, while at the same time lowering noise levels. T he new design still includes two axial fans, but Nvidia heavily redesigned the PCB and shortened it so that the ‘back’ of the card (away from the video ports) consists of just a fan, heatpipes, radiator fins, and the usual graphics card shroud. Nvidia has radically altered the design of its Founders Edition cards for the RTX 30-series. Let’s take a closer look at the Ampere SM found in the GA102 and GA104.

Meanwhile, the GA102 drops most of the FP64 functionality and instead includes ray tracing hardware, plus some other architectural enhancements. The GA100 focuses far more on FP64 performance for scientific workloads, as well as doubling down on deep learning hardware. If you’re wondering, that’s 52% more transistors than the TU102 chip used in RTX 2080 Ti, but in a 17% smaller area.Īmpere ends up as a split architecture, with the GA100 taking on data center ambitions while the GA102 and other consumer chips have significant differences. Regardless, GA102 is still a big and powerful chip, boasting 28.3 billion transistors packed into a 628.4mm square die. But they might have cost more, only been available in limited quantities, or maybe they would have been delayed a few more months. Could the consumer Ampere GPUs have been even better with 7nm? Perhaps. The general consensus is that TSMC’s N7 node is ‘better’ overall, but it also costs more and is currently in very high demand - including from Nvidia’s own A100. The GA102 is the first GPU from Nvidia to drop into the single digits on lithography, using Samsung’s 8N process. But here’s the highlight reel of the most important changes:

If you want the full rundown of everything that’s changed compared to the Turing architecture, we recommend starting there.
We have a separate article going deep into the Ampere architecture that powers the Nvidia GeForce RTX 3080 and other related GPUs.
Nvidia has thrown down the gauntlet, clearly challenging AMD’s Big Navi to try and match or beat what the Ampere architecture brings to the table. After months of waiting, we finally have independent benchmarks and testing data.
Nvidia’s GeForce RTX 3080 Founders Edition is here, claiming the top spot on our GPU benchmarks hierarchy, and ranking as the best graphics card currently available - provided you’re after performance first, with price and power being lesser concerns. Nvidia GeForce RTX 3080 Founders Edition: Hail to the King!
