With prices starting at $1,000, the new Nvidia ray tracing GPUs – the RTX A4000 and Nvidia RTX A5000 – should hit the sweet spot for engineers and designers


Nvidia has expanded its professional family of desktop workstation GPUs, with the launch of two new Nvidia RTX cards based on its ‘Ampere’ architecture.

The Nvidia RTX A4000 (16 GB) and the Nvidia RTX A5000 (24 GB) will join the flagship Nvidia RTX A6000 (48 GB), which we reviewed earlier this year.

These are mid-range ‘Quadro’ GPUs in everything but name, as Nvidia is in the process of retiring that long-serving workstation brand. They offer more memory than their consumer GeForce counterparts and come with pro drivers with certification for a wide range of CAD/BIM and other 3D applications.

As with all ‘Ampere’ Nvidia RTX GPUs, the new models feature new RT Cores, Tensor Cores and CUDA cores – all of which can be used concurrently for ray tracing, shading and denoising tasks in RTX-enabled software such as Unreal Engine, Enscape, Autodesk VRED, Chaos Vantage and Nvidia Omniverse.

Nvidia RTX GPUs can also be used with non RTX software, such as 3D modelling, VR and AI. Both GPUs support PCIe Gen 4, which offers double the bandwidth of PCIe Gen 3, so data can move from CPU to GPU much quicker.

Nvidia is also addressing the mobile workstation market with four new ‘Ampere’ Nvidia RTX laptop GPUs – the Nvidia RTX A2000 laptop (4 GB), Nvidia RTX A3000 laptop (6 GB), Nvidia RTX A4000 laptop (8 GB) and Nvidia RTX A5000 laptop (16 GB).

In addition, Nvidia continues to cater to users of 3D CAD tools that don’t necessarily need RTX ray tracing capabilities.

It has launched two new entry-level laptop GPUs, the Nvidia T1200 and Nvidia T600, which are based on Nvidia’s previous-generation Turing architecture. Expect to find these in ultra slim mobile workstations.

This is an important launch for Nvidia as it gives architects, engineers and product designers – some of the key target users for these types of GPUs – a much more affordable entry into the significantly enhanced Nvidia RTX ‘Ampere’ family. The estimated street price of the Nvidia RTX A4000 and RTX A5000 is $1,000 and $2,250 respectively.

On paper, the single slot Nvidia RTX A4000 looks to be a substantial upgrade to the Turing-based Nvidia Quadro RTX 4000 it replaces, which impressed us greatly when it launched in 2019.

With 16 GB of GDDR6 ECC memory, twice that of the Quadro RTX 4000, it should be able to handle most datasets used for real time visualisation or GPU rendering in product development.

It also has more than double the number of CUDA cores, and a significant uplift in single precision performance and Tensor performance. And as it’s a single slot GPU with a max power consumption of 140W, it will be available in a huge range of desktop workstation form factors, including the new HP Z2 Tower G8 also launched today.

Similar things can be said of the dual slot Nvidia RTX A5000, which Nvidia says offers the same levels of performance as a Turing-based Quadro RTX 6000 but is less than half the price.

With 24 GB of GDDR6 ECC memory it’s only a 50% uplift on the Quadro RTX 5000 it replaces but the RTX A5000 is expandable to 48 GB by connecting two GPUs together using Nvidia NVLink. The RTX A5000 also supports Nvidia RTX vWS (virtual workstation software) so the GPU can deliver multiple high-performance virtual workstation instances that enable remote users to share resources.

It’s interesting to note that Nvidia has not released a replacement for the CAD-focused Quadro P2200 (5 GB), which was a small improvement over the Quadro P2000, which we reviewed way back in 2017. However, we expect there to be a second wave of Nvidia RTX GPUs released later this year that cater more to entry-level users.

Nvidia Ampere pro laptop GPUs

Nvidia has launched a wider spread of professional Nvidia RTX laptop GPUs, from the entry-level to the high-end, which should be available in Q2 this year in mobile workstations from all the usual suspects including HP, Dell, and Lenovo.

This includes the Nvidia RTX A2000 Laptop (4 GB GDDR6), RTX A3000 Laptop (6 GB GDDR6), RTX A4000 Laptop (8 GB GDDR6), and RTX A5000 Laptop (16 GB GDDR6).

It’s good to see Nvidia giving these new GPUs a Laptop suffix. In the past there has been some confusion as to whether or not these are the same GPUs found in desktop workstation.

However, in addition to having a smaller power budget than their desktop counterparts, the new laptop GPUs also have fewer CUDA, Tensor and RT cores
