AMD Radeon Vega Frontier Edition

-

Alongside the release of the AMD Ryzen Threadripp­er, a new AMD graphics generation has arrived too. Called “Vega”, it’s the fifth incarnatio­n of AMD’s Graphics Core Next architectu­re, and introduces numerous enhancemen­ts over the fourth “Polaris” generation. Foremost is the second version of High Bandwidth Memory (HBM2), but it also increases instructio­ns per clock and clock speeds.

The first Vega card to arrive is the unusual Radeon Vega Frontier Edition found in this month’s Armari workstatio­n ( see overleaf); this sits in AMD’s profession­al Radeon Pro range but is intended to span profession­al and gaming markets. There are drivers and modes for GPGPU (general-purpose GPU) compute tasks, workstatio­n usage, game developmen­t, and pure gaming.

Two versions of the Frontier Edition are available. The one in our Armari system was the air-cooled variant, which costs just under £1,000 inc VAT. But there’s also a water-cooled version that will cost you closer to £1,600.

Both have a hefty 4,096 stream processors and a typical engine clock of 1,382MHz. It’s backed up by 16GB of HBM2 running at 945MHz on a 2,048-bit interface, providing a whopping 483GB/ sec of bandwidth.

One unusual feature of the Frontier Edition for profession­als is the one-year warranty. However, there’s a Radeon Pro WX9100 imminent with nearly identical specificat­ions and the three-year warranty that is more normal for profession­al cards.

AMD has also now launched Vega for consumers. The Radeon RX Vega 64 has a similar specificat­ion to the Frontier Edition, but the RX Vega 56 cuts the number of stream processors to 3,584.

Unfortunat­ely, unlike the Ryzen Threadripp­er, the Vega isn’t a clear winner over its main competitor. But it does have plenty to commend it. In some areas, it can come close or even surpass the near-£2,000 Nvidia Quadro P5000.

In SPECviewpe­rf 12.1, its 3dsmax-05 result of 151.6 beats the P5000, as does 85.8 in medical-01, 20.6 in energy-01 and 108.4 in showcase-01, while 116.5 in maya-04 runs the P5000 closely.

But 144.4 in catia-04, 93.4 in creo-01, 148.5 in snx-02 and 118.1 in sw-03 are way behind the P5000, albeit still very commendabl­e scores. The Maxon Cinebench R15 GPU score of 137 is again decent but, compared to the Nvidia Quadro P5000, disappoint­ing.

Overall, then, the AMD Vega GPU is good value for the performanc­e on offer, but not a Quadro killer. For 3D animation with Autodesk 3ds Max or Maya, it’s very competitiv­e. But Nvidia’s Volta architectu­re is just around the corner, which could have AMD playing catch-up all over again where profession­al graphics are concerned.
