Nvidia's GTC keynote included a variety of AI-related announcements, the launch of the Path Tracing SDK, and even a new software library for computational lithography named cuLitho. However, in the middle of all these, there was still time to introduce new laptop and desktop workstation GPUs.
For desktop users that wanted an SFF workstation GPU, Nvidia launched the RTX 4000 SFF Ada. This dual-slot GPU only occupies a fraction of the space of other mid-range workstation graphics cards, with just 16.7cm in length, and has a 70W TDP. However, don't let its reduced dimensions and apparent low power consumption fool you.
With 20GB of GDDR6 memory running at 16Gbps across a 160-bit memory interface, the GPU offers a maximum bandwidth of 320GB/s. In addition, the GPU packs 6,144 CUDA cores, 192 Tensors and 48 RT cores for up to 19.2 TFLOPS of single-precision compute performance, up to 44.3 TFLOPS of RT performance, and up to 306.8 TFLOPS of Tensor performance. For image output, there's 4x Mini DisplayPort 1.4a.
As for the mobile parts, Nvidia launched the Ada-based RTX 5000, 4000, 3500, 3000 and 2000 Ada mobile workstation GPUs. As previous rumours stated, the RTX 5000 would be the equivalent of the RTX 4090 laptop GPU, while the RTX 4000 would match the RTX 4080 laptop GPU specs. The RTX 3500 and 2000 don't have an RTX 40 mobile counterpart, but the RTX 3000 has (RTX 4070). The table below summarises the new RTX Ada mobile workstation GPU series specs.

Nvidia states the RTX 4000 SFF Ada will release later this year with a price of around $1250. As for RTX Ada-powered laptops, the company confirmed they would be available starting this month.
