In the leadup to the launch of a new graphics chip from one of the two big vendors, rumors swirl like storm clouds above Kansas in the spring. Right now, AMD's upcoming RX Vega is the unreleased chip the rumor-mongers can't stop talking about. Today's dose of Vega rumors pertains to an entry in FutureMark's benchmark database that's believed to have come from a system with an AMD Ryzen 7 1800X and some type of Vega card. The system in question scored 5950 points overall, with a graphics tally of 5721 and a CPU score of 7699. Grab the salt jug for this one.
The graphics score of 5721 puts the tested chip roughly in line with Nvidia's GeForce GTX 1070, though we have to warn people about concluding that a single unconfirmed benchmark from an unknown source with early drivers is representative of the final product. Our editor-in-chief Jeff Kampman is also suspicious of the low score, given that he spent time with an actual Vega system during CES.
The "Generic VGA" card in question has 8 GB of memory and runs at a reported 1200 MHz, a figure that's in line with previous alleged leaks of Vega performance potential. Earlier rumors suggested that AMD will ship Vega with 4 GB and 8 GB HBM2 memory configurations. AMD fans and shareholders may be unimpressed with the rumored performance figures, but clock speeds of engineering sample cards tend to be somewhat lower than final retail models—never mind the fact that whatever drivers exist are probably in an early stage of development.
If one were to assume that Vega has 4096 stream processors and that each SP can perform a pair of floating-point operations per clock cycle, the 1200 MHz card on display would deliver a theoretical 9.8 TFLOPs. This figure is substantially higher than the 6.5 TFLOPS of Nvidia's GeForce GTX 1070 and a bit higher than the computing power of the GeForce GTX 1080. For reference, the all-conquering GeForce GTX 1080 Ti can execute a whopping 11.3 TFLOPS. Of course, this discussion all revolves around assuming that the benchmark scores and figures actually came from a Vega graphics card.
