Spotlight on the NVIDIA RTX A4500

The launch of the NVIDIA RTX™ A4500 professional graphics card last November was met with some bemusement, if not outright scepticism, by some reviewers.

Why, with the RTX™ A4000 (16 GB) and RTX™ A5000 (24 GB) already on the market, was there a need to plug a gap for which there didn’t appear to be a ready market? But they hadn’t reckoned with a global semiconductor shortage which made accessibility of both cards sporadic, thereby pushing up the price of both.

Supplying a truncated version of the RTX™ A5000, using silicon and components already at its disposal, was a smart move by NVIDIA which was, simultaneously, able to provide customers with improved performance and availability of supply.

With a twin slot PCIe form factor, the A4500 looks indistinguishable to the A5000 and is much closer in spec to it than to the single slot RTX™ A4000. With 4GB less memory, it features the same GA102 graphics processor, albeit with some cores disabled, a slower clock speed and slightly lower power draw – 200 vs 230 Watts via a single, eight-pin PCIe power connector.

Similar to the A5000, it has four DisplayPort 1.4a connectors, 3D stereo and NVLink, allowing two A4500 GPUs to be connected to scale performance and double memory to 40 GB in supported applications.

Like it’s bigger brother, the A4500 combines high performance, enterprise reliability, and the latest RTX technology to help designers achieve optimum performance from their workstation.

Combining 56 second-generation RT Cores, 224 third-generation Tensor Cores, and 7,168 CUDA® cores with 20GB of graphics memory, it operates across a 320-bit bus interface at pin speeds of up to 16 Gbps, Providing the GPU with 640 GB/s of bandwidth.

All this firepower turbo boosts ultra-high-resolution rendering, artificial intelligence, graphics, and a range of other memory-intensive tasks including computer aided design, virtual reality, and multi-display. The core count makes the Ampere GPU featured on the A4500 the most cut-down workstation configuration of the GA102 GPU, with 66% active cores. The graphics processor has die area of 628 mm² and 28,300 million transistors.

Unlike the GeForce RTX 3090 Ti, which uses the same GPU but has all 10752 shaders enabled, NVIDIA has disabled some shading units on A4500 to reach the product’s target shader count. It features 7168 shading units, 224 texture mapping units, and 96 ROPs.

The GPU operates at 1050 MHz, which can be boosted to 1650 MHz, with memory running at 2000 MHz, 16 Gbps effective. Being dual-slot, it draws power from 1x 8-pin power connector, with power draw rated at 200 W maximum. Display outputs include: 4x DisplayPort 1.4a. RTX A4500 is connected to the rest of the system using a PCI-Express 4.0 x16 interface. The card measures 267 mm in length, 112 mm in width, and features a dual-slot cooling solution.

Designers have the reassurance of knowing that the cards are certified with a range of professional applications, tested by leading independent software vendors
(ISVs) and workstation manufacturers, and backed by a global team of support specialists.

Built on the NVIDIA Ampere architecture it is now available for inclusion in all G2 Digital’s rackmount builds from a 2U Nano or larger.
