In a Reddit AMA yesterday evening Raja Koduri, Senior VP and Chief Architect of Radeon Technologies Group at AMD, answered questions about the upcoming RX Vega line. One of those pertained to performance. Vega FE “employs two stacks of HBM2”, according to Koduri, offering speeds of up to 480GB/s.
AMD promised more details on its 14nm FinFET Vega architecture-which debuted earlier this week in the form of the compute-focused Radeon Vega Frontier Edition-at Computex in May. In comparison, the GTX 1080 Ti and Titan Xp from NVIDIA top out at 11.3TFLOPS and 12TFLOPS respectively. AMD also showed how their High-Bandwidth Cache Controller (HBCC) improved performance, with Rise of the Tomb Raider running 35 percent faster with HBCC on vs. HBCC off. The bad news is that this consumer version of the Vega chipset will – most probably – be delayed. Those same rumors put the Nova as superior to the Frontier Edition, the Eclipse as slightly inferior, and the Core likely as a compact Nano replacement.
Elsewhere in the AMA, Koduri confirmed a few other Vega titbits, including that it’s possible to run Vega FE with 8-pin and 6-pin PCIe power connectors, rather than the two 8-pin connectors that made it onto production boards for “extra headroom”.
This launch is squarely aimed at the mass adoption market, where games like “Overwatch” or “Battlefield” are carefully balanced for performance on a wide range of PC platforms.
This bodes well for Vega. The AMD Radeon Vega Frontier Edition will be available to purchase from “late June“.
Bugfixes include a NieR: Automata crash, long Forza: Horizon 3 load times, an issue with CrossFire systems where the main display adapter could appear disabled in Radeon settings, and a system hang when entering sleep or hibernate with the RX 550.
“[The] primary vision with Vega was to establish our next generation architecture that is capable of dealing with large data-sets (tera, peta, exa, etc.) From a gaming perspective we wanted to build a product that tackles the challenging 4K@60Hz for AAA gaming”.
