NVIDIA has finally unveiled and officially announced their new 2nd generation RTX graphics cards, the NVIDIA GeForce RTX 30 Series Family. Powered by NVIDIA’s Ampere architecture, the graphics cards are said to offer “the greatest-ever” generation leap; twice the performance over Turing. The NVIDIA GeForce RTX 3080 graphics card is the flagship card starting at $699. Also, NVIDIA announced the RTX 3070 and the RTX 3090 “BFGPU”, which I’ll discuss in their respective articles. In this article, let’s learn more about the new flagship RTX 3080.

NVIDIA GeForce RTX 3080 Founders Edition Graphics Card
Let’s start this article with a short FAQ since it’s easier to digest and get the gist out of this new release.
How many CUDA cores and what’s the memory size of the new RTX 3080?
How fast is the GeForce RTX 3080 graphics card?
Is the GeForce RTX 3080 faster than RTX 2080 Ti?
How much power does the RTX 3080 consume? Is it power-hungry?
What is the recommended PSU for the RTX 3080?
How much is the GeForce RTX 3080?
Will the GeForce RTX 3080 fit inside my casing?
When will the RTX 3080 become available?
Should I upgrade if I own a GTX 10 series graphics card? Is the RTX 3080 worth it?
In addition, the GeForce RTX 3080 has three DisplayPort 1.4a out and an HDMI 2.1. NVIDIA removed the USB-Type C for VR headsets and there is no NVLink or SLI bridge. Yes, that’s right. SLI / multiple-GPU is pretty much dead.
At this point, I don’t think that the RTX 3080 is the direct replacement of the RTX 2080 Ti. I don’t think that the RTX 3090 is the direct successor of the RTX 2080 Ti as well, since the RTX 3090 succeeds the TITAN RTX.
I also noticed that there is a huge price gap between the RTX 3080 and RTX 3090, $699 vs $1499. So, perhaps, NVIDIA may release a certain “RTX 3080 Ti” in the future or when AMD releases the Big Navi. Who knows? Don’t quote me on this as I am just speculating as well.
NVIDIA RTX 30 Series Features
Below are the “cutting-edge” technologies that the new RTX 30 Series GPUs and NVIDIA Ampere architecture have to offer:
- New streaming multiprocessors: The building block for the world’s fastest, most efficient GPU, delivering 2x the FP32 throughput of the previous generation, and 30 Shader-TFLOPS of processing power.
- Second-gen RT Cores: New dedicated RT Cores deliver 2x the throughput of the previous generation, plus concurrent ray tracing and shading and compute, with 58 RT-TFLOPS of processing power.
- Third-gen Tensor Cores: New dedicated Tensor Cores, with up to 2x the throughput of the previous generation, making it faster and more efficient to run AI-powered technologies, like NVIDIA DLSS, and 238 Tensor-TFLOPS of processing power.
- NVIDIA RTX IO: Enables rapid GPU-based loading and game asset decompression, accelerating input/output performance by up to 100x compared with hard drives and traditional storage APIs. In conjunction with Microsoft’s new DirectStorage for Windows API, RTX IO offloads dozens of CPU cores’ worth of work to the RTX GPU, improving frame rates and enabling near-instantaneous game loading.
- World’s fastest graphics memory: NVIDIA has worked with Micron to create the world’s fastest discrete graphics memory for the RTX 30 Series, GDDR6X. It provides data speeds of close to 1TB/s system memory bandwidth for graphics card applications, maximizing game and app performance.
- Next-gen process technology: New 8N NVIDIA custom process from Samsung, which allows for higher transistor density and more efficiency.

Are you planning to get an RTX 3080? What brand will you be getting? Or do you plan to get the “Big Ferocious GPU” RTX 3090 instead?
