AMD finally unveiled its first Vega graphics card, but much to the chagrin of gamers, it turned out to be a professional part for data scientists and the like. Drats! The good news, however, is that Vega presumably will be launching to consumers soon, and some of those cards will be faster than the Frontier Edition.
In a Reddit AMA, AMD’s Radeon boss Raja Koduri said he wasn’t able to divulge a specific launch date or pricing information, but did want to address some of the “rumors and innuendo” floating around. One of those pertained to performance.
When asked if consumer variants of Vega would be as fast as the Frontier Edition, Koduri did not dodge the question or offer a canned response. Instead, he said that “consumer RX will be much better optimized for all the top gaming titles, and flavors of RX Vega will actually be faster than Frontier version!”
As a refresher, the Frontier Edition boasts 64 compute units, which works out to 4,096 stream processors, the same as AMD’s Radeon Fury X. It also has 16GB of HMB2 memory on a 2,048-bit bus, clocked at around 1,865MHz for 480GB/s of memory bandwidth.
AMD is claiming that its Frontier Edition card can deliver 25 teraflops (TFLOPS) of half-precision FP15 compute performance and 13 TFLOPS of single-precision FP32 compute performance. Based on the 13 TFLOPS figure, that would give some Vega cards a clockspeed in the range of 1550-1600MHz.
As a point of comparison, Nvidia’s Titan Xp delivers 12 TFLOPS of FP32 compute power. It’s not all TFLOPS, as Nvidia has traditionally delivered more gaming performance per theoretical TFLOPS (eg, 1070 is 7.3 TFLOPS compared to 8.6 TFLOPS on Fury X), but with 50 percent more compute compared to Fury X, Vega is shaping up to be very competitive. 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.
We don’t officially know how many Vega SKUs there will be for consumers but…
