It looks like one of AMD's upcoming Navi graphics cards have appeared on the 3DMARK Time Spy database, coming user genesis_surge . The graphics card is unknown at this time, but given its listed boost clock of 1,878MHz, our guess is that this is AMD's Radeon RX 5700 XT.This benchmark listing was first uncovered by WCCFTech's Keith May , who notes that the benchmarked PC was similar to his own test system, albeit with a stock i7-8700K, with his system featuring an all-core 5GHz overclock. 3200MHz DDR4 memory was also used with this hardware setup.In all, this system offered a final score of 8575 points, 8719 GPU points and 7843 CPU points, placing it higher than May's Radeon RX Vega 64 and Nvidia's GTX 1080. This placed the unknown Radeon graphics card, which is thought to be a Radeon RX 5700 XT slightly under Nvidia's RTX 2070 Founders Edition (which achieved a Graphics score of 8901), though this could be due to his test system's higher CPU clock speeds.What this shows is a significant performance boost when compared to AMD's existing Vega series graphics cards in 3DMARK's DirectX 12 test suite. That said, similar performance to Nvidia's RTX 2070 will place Radeon in a tough position if they don't get their pricing right.
