Nvidia has unveiled several new models for its RTX line of cards aimed at design and video professionals, which has replaced the Quadro line. On the one hand, Nvidia supplements the RTX A6000, which has been available for a short time, with the two cheaper (and less powerful) desktop models RTX A5000 and A4000. On the other hand, there are the new models RTX A2000, RTX A3000, RTX A4000 and RTX A5000 with Ampere architecture and the two models T1200 and T600 with Turing architecture especially for laptops. ;)
Desktop GPUS RTX A5000 and RTX A4000. The desktop version of the  RTX A4000 has 16GB of GDDR6 memory connected via 256-bit interface and a GA106 GPU with 6,144 CUDA and 48 Tensor cores, while the RTX A5000 has 24GB (with either GDDR6 or ECC memory) connected via 384-bit bus interface and a GA102 GPU with 8,192 CUDA cores and 64 Tensor cores. The RTX A5000 can be expanded to 48 GB via Nvidia NVLink with two RTX A5000 GPUs. Like the RTX A6000, both use PCIe Gen4, which doubles the available bandwidth, as well as Nvidia&s new Ampere architecture. The new RTX desktop graphics cards thus feature 2nd generation RT cores, whose data throughput is up to twice as fast as that of the previous generation and can execute ray tracing, shading and denoising tasks in parallel. In addition, they have 3rd generation Tensor cores with up to 2x throughput as well, and CUDA cores whose FP32 throughput is up to 2.5x higher. ;) Nvidia RTX A5000 Both feature active cooling via fan to dissipate the waste heat of the 230W (A5000) or 140W (A4000) TDP and four DisplayPorts version 1.4. For comparison, the top-of-the-line RTX A6000 features a GA102 GPU with 10,752 CUDA and 336 Tenosor cores, as well as 48GB of GDDR6 memory (96GB via NVLink) and a tDP of 300W. RTX A5000, RTX A4000, RTX3000 and RTX A2000 for notebooks. The notebook versions of the RTX A4000 and RTX A5000 are somewhat slimmed down compared to the desktop versions: thus, the mobile RTX A4000 has only 8GB and 5,120 CUDA cores and the A5000 16GB and 6,144 CUDA cores - in return, the TDP has been lowered in each case to 80 to 140 watts (A4000) and 80 to 165 watts (A5000) for mobile operation - depending on the OEM&s implementation. The RTX A3000 comes with 6GB and 4,096 CUDA cores and the RTX A2000 with 4GB and 2,560 CUDA cores. Availability. The new NVIDIA RTX desktop GPUs will be available from global channel partners and OEMs starting later this month, and the new NVIDIA RTX laptop GPUs are expected to be available in mobile workstations from global OEMs in Q2 of this year.  more infos at bei nvidianews.nvidia.comdeutsche Version dieser Seite: Nvidia bringt neue Profi-Grafikkarten für Workstations: RTX A5000 und RTX A4000 |
