Nvidia RTX A2000 vs NVIDIA RTX A3000 Laptop GPU vs NVIDIA RTX A4000 Laptop GPU

The Nvidia RTX A2000 Desktop GPU is a professional graphics card for small workstation PCs. It is based on the GA106 graphics chip, which is used in the GeForce RTX 3050 or GeForce RTX 3060 consumer graphics cards, among others. However, the GA106 only works with 3,328 active shader units, as well as 26 RT cores and 104 tensor units. The VRAM comprises 12 GB GDDR6 and communicates via a 192-bit memory interface. This results in a memory bandwidth of 288 GB/s.

The professional graphics cards from Nvidia offer certified drivers that are optimized for stability and performance in professional applications (CAD, DCC, medical, prospecting, visualization applications). This results in many advantages over consumer graphics cards.

Compact design and flexibility:

The RTX A2000 is designed in a low-profile form factor, making it ideal for smaller workstations or systems where space is a limited resource. Despite its compact size, the Nvidia RTX A2000 offers considerable computing power.

The graphics card is ideal for 3D modeling, CAD applications, video editing and visual effects where high precision and speed are paramount. Thanks to the combination of CUDA, Tensor and Raytracing cores, the Nvidia RTX A2000 offers significant performance improvements in the areas of real-time rendering and AI-supported image processing.

Energy efficiency and power consumption:

The NVIDIA RTX A3000 Laptop GPU or A3000 Mobile is a professional graphics card for mobile workstations. It is based on the GA104 Ampere chip and offers a similar performance to the consumer GeForce RTX 3060 Laptop GPU. However, it offers 256 more CUDA cores (4,096 versus 3,840) and is based on the bigger GA104 chip. The A3000 also supports PCIe 4.0 and integrates 32 RT-cores and 128 Tensor cores of the Ampere generation. It is available in different variants from 60 - 130 Watt (TGP) with different clock speeds (and performance). The GPU supports eDP 1.4b to connect the internal monitor and DisplayPort 1.4 and HDMI 2.1 for external connections.

In 2022 Nvidia released a slightly improved version of the RTX A3000 with more and faster graphics memory. The original 6 GB with 11 Gbits has been doubled to 12 GB GDDR6 clocked at 14 Gbits.

There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, WhisperMode).

The raw performance should be similar to the GeForce RTX 3060 for laptops at the same TGP level. Both GPUs depend heavily on good cooling and a high TGP for good performance. At a similar power consumption level the RTX A3000 should be clearly faster than the old Quadro RTX 3000 and 3000 Max-Q. 

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The A3000 only uses 4,096 of the 6,144 CUDA cores. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA104 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip).

The NVIDIA RTX A4000 Laptop GPU or A4000 Mobile is a professional graphics card for mobile workstations. It is based on the GA104 Ampere chip and similar to the consumer GeForce RTX 3080 Laptop GPU. It offers the same 5.120 graphics cores, 40 RT cores, 160 Tensor cores and 8 GB GDDR6 graphics memory with a 256 Bit memory bus. It supports PCIe 4.0 and will be available in different variants from 80 - 140 Watt (TGP) with different clock speeds (and performance). The GPU supports eDP 1.4b to connect the internal monitor and DisplayPort 1.4 and HDMI 2.1 for external connections.

There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, WhisperMode).

The raw performance should be similar to the GeForce RTX 3070 for laptops at the same TGP level. Both GPUs depend heavily on good cooling and a high TGP for good performance. At a similar power consumption level the RTX A4000 should be clearly faster than the old Quadro RTX 4000 and 4000 Max-Q. The desktop variant of the A4000 however, is a lot faster.

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The A4000 only uses 5,120 of the 6,144 CUDA cores. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).
