AMD unveils Radeon Pro W6400

AMD has announced a new entry-level graphics card, based on the RDNA2 architecture, aimed at the workstation market and with very low power consumption: Radeon Pro W6400. The product completes the line-up of RDNA 2 professional video cards, ranging from the W6800 and W6600, up to the new W6400. Radeon Pro W6400 has 12 CUs for a total of 768 Stream Processors, coupled with 4GB of GDDR6 memory with a maximum effective bandwidth of 128GB / s. To help boost performance, the GPU will also be equipped with a small 16MB Infinity Cache.

This shouldn't be a problem for motherboards that support PCIe 4.0, as four PCIe 4.0 lanes should be perfectly adequate. However, if you intend to use it in a motherboard limited to PCIe 3.0 - or lower - you may suffer from reduced performance due to the lower bandwidth. AMD promises up to 3.52 TFLOP FP32 single precision and 7.07 TFLOPS FP16 half precision for the W6400. Compared to the WX 3200 and older competitors like the NVIDIA T600, the W6400 offers a substantial increase in performance, at least when it comes to FP16 and FP32 synthetic computing.

However, the W6400 only supports a maximum of two DisplayPort 1.4 connections instead of the traditional four we're used to seeing. Versions of this GPU will also arrive on the laptop market in the form of the W6300M ​​and W6500M. In terms of specs, the W6300M ​​will be slightly less powerful than the W6400 and will only have 2GB of RAM. However, the W6500M will be significantly faster, with official throughput of 10.61 TFLOP FP16 half-precision and 5.3 TFLOP FP32 single-precision. Finally, all GPUs support AV1 encoding / decoding and H.265 decoding.

At the moment, the prices and availability of the Radeon Pro W6400 remain unknown, but we will surely know more over the next few weeks.

AMD Radeon Pro W6400 Flexes 6nm RDNA 2 Muscle For Budget And Mid-Range Workstations

AMD is fleshing out its current-generation Radeon Pro lineup with RDNA 2 underneath the hood with the introduction of the Radeon Pro W6400. It slides into the lineup beneath the existing Radeon Pro W6600 for medium to high-level workloads, and the Radeon Pro W6800 designed for high to extreme workstation workloads. So what does that mean for the Radeon Pro W6400?A more affordable path into RDNA 2 territory for workstation builds, for one. It also ranks as AMD's first workstation graphics card to feature a GPU built on a 6-nanometer manufacturing process. This is still the same underlying architecture, so you can consider the shift from 7nm to 6nm as more of a tune-up. Same goes for the just-launched Radeon RX 6500 XT we reviewed today.

AMD is shipping the Radeon Pro W6400 in a half-height, single-slot form factor measuring 6.6 inches (168mm) long. The GPU packs 5.4 billion transistors and wields 12 compute units, 768 stream processors, and 12 Ray accelerators. According to AMD, it pumps out 3.54 TFLOPs of single-precision (FP32) throughput and 7.07 TFLOPs of half-precision (FP16) throughput.

The card also features 4GB of GDDR6 memory running at 16Gbps, linked to a 64-bit memory interface for 128GB of memory bandwidth. L3 Infinity Cache checks in at 16MB.

Similar to the Radeon RX 6500 XT and RX 6400 (both consumer cards), the Radeon Pro W6400 leverages PCIe 4.0 x4 rather than x8 or x16. That shouldn't be an issue, though, as there's little chance it is going to be bandwidth-starved. To that point, AMD claims its latest Pro model beats out NVIDIA's T600 in a variety of workloads. Here are a couple of benchmark charts the company shared...

We can't speak to AMD's results from its internal testing, at least not quite yet. However, we will have a review of the Radeon Pro W6400 very soon (possibly later today or by tomorrow at the latest) with our own collection of benches and accompanying analysis, so stay tuned for that.

As for AMD's testing, it was performed on a machine configured with an Intel XeonW-2125 processor, 32GB of RAM, and Windows 10 Pro with a pre-production sample of the Radeon Pro W6400. The data is over a month old, so it's possible that updated drivers and finalized hardware could boost performance further. We'll see.

AMD also added a couple of mobile solutions to its Radeon Pro W6000 series. They include the Radeon Pro W6500M (1,024 stream processors, 4GB GDDR6, 64-bit bus width, 16MB Infinity Cache) and Radeon Pro W6300M (768 stream processors, 2GB GDDR6, 32-bit bus width, 8MB Infinity Cache).

The Radeon Pro W6400 will be available this quarter starting at $229. Then later this year, pre-built OEM systems will begin employing the aforementioned mobile GPUs.
