Nvidia's GB202 and GB203 GPUs Tape-out and Related Predictions

TapTechNews June 1st news, the source @kopite7kimi tweeted on May 29th, indicating that Nvidia's GB202 and GB203 GPUs have tape-out (TapeOut), and it is estimated to be equipped on Nvidia's GeForce RTX 5090 and RTX 5080 graphics cards.

TapTechNews note: Tape-out (tape-out) refers to manufacturing chips on an assembly line through a series of process steps, and it is the final step in integrated circuit design, that is, submitting to manufacturing. Tape-out is also known as trial production. Simply put, after designing the circuit, first produce a few dozen pieces for testing. If the test passes, then start mass production according to this appearance.

The source previously revealed that Nvidia is considering downsizing the size of the GeForce RTX 5090 Founders Edition graphics card to a dual-slot dual-fan design.

Currently, Nvidia's GeForce RTX 4090 and RTX 4080 Founders Edition GPUs use a three-slot and dual-axis technology fan design. If the news is true, it is not clear what kind of design the GeForce RTX 5090 Founders Edition will adopt.

There are two possibilities:

A dual-slot design means that Nvidia has completely changed the heat dissipation solution so that it can dissipate more than 400 watts in a smaller package.

Nvidia's Blackwell GPU is a very excellent chip that can achieve high performance without generating high heat.

In addition, the source Panzerlied posted on the Chiphell forum stating that GB2020 adopts 16 modules with a 448-bit width.

If 5090 is equipped with 28GB GDDR7 VRAM as rumored, with a speed of 28 Gbps, then it may only need to use 14 memory modules of GB202. Theoretically, the 448-bit bus will provide about 1.5 TB/s of memory bandwidth for this flagship GPU, which is 50% higher than 4090.
