AMD Radeon Pro W5700 - Navi And RDNA For Creative Professionals
In addition to using its latest GPU design with the Radeon Pro W5700, AMD is using the opportunity to somewhat simplify its naming convention. Workstation-class, pro-vis GPUs still carry the Radeon Pro moniker, but the WX designation is being nixed and model numbers unified. The Radeon Pro W5700 and Radeon RX 5700 are based on the same GPU design, hence the similar model numbers. Got it? Cool.
Navi is a major departure from AMD’s previous-generation Vega and Polaris GPUs, as you’ll surmise if you carefully inspect the spec table below. If you’d like more of a deep-dive on Navi, however, we’ve got you covered too. This piece covers the GPU architecture in-depth. For now though, let’s dig into the new Radeon Pro W5700 and see what makes the card tick...
The Radeon RX 5700, the new Radeon Pro W5700 is built around AMD's Navi 10 GPU. The GPU at the heart of the card is manufactured using TSMC’s 7nm process node and is comprised of approximately 10.3 billion transistors. And its die size is roughly 251 square millimeters, which makes it a fraction of the size of the Vega-based GPU powering the previous-gen Radeon Pro WX 8200.
AMD’s current flagship, Navi-based GPU, the Radeon RX 5700 XT, features a fully-enabled Navi 10 GPU with 40 Compute Units, each with 64 Steam Processors, for a total of 2,560. The AMD Radeon Pro W700’s GPU is scaled back though and is more in-line with the non-XT Radeon RX 5700. The Radeon Pro W5700 has the same memory and ROP configuration as the top-end Navi 10, but four CUs have been disabled. The Radeon Pro W5700 has 36 CUs, a total of 2,304 stream processors, with typical GPU clocks hovering between 1630-1880MHz. Max board power is 205 watts, but note, that takes into account 15W+ for the USB port. If that port is unused, typical power is around 188 watts.
GDDR6 memory over a 256-bit interface with an effective data rate of 14Gbps, which equates to peak memory bandwidth of 448GB/s. At it default clocks, the Radeon Pro W5700 doesn’t quite match the previous-gen Radeon Pro WX 8200 in terms of compute performance or memory bandwidth, but Navi, which is based on a more efficient architecture, does improve IPC and its peak pixel fillrate is much higher.
Radeon Pro WX 8200, with similar coloring and boxy, blower-style cooler. There is a hefty array of heatsink fins under the gorgeous blue shroud, that sits directly atop the GPU and RAM, with the barrel-type fan offset towards the back of the card, pumping air out of the system, through vents in the card’s mounting bracket.
The Radeon Pro W5700 features 8-pin and 6-pin PCIe power feeds, which provide plenty of headroom to the card – it might even be a bit of overkill. Between the PCIe slot and the supplemental feeds, 300W will be available to the Radeon Pro W5700 series cards (150 + 75 + 75), which is nearly 100W higher than its max board power rating.
VR HMD applications. The remainder of the case bracket is essentially one large vent, for exhausting warm air.
Now, let's get her plugged into the test rig and see how she performs...
