An unknown AMD GPU (66AF:F1) has appeared on CompuBench, and some believe it could be a Navi part. GFXBench scores allude to a card that exceeds the Radeon RX Vega 64 in graphics capability but falls behind in certain compute tests, even against the Vega 56. Notebook Check advises this could actually be a Vega 20 GPU (“we've seen Linux drivers listing 0x66AF as Vega 20”). A comparison of the GFXBench scores of the AMD 66AF:F1 with the Radeon RX Vega 64 shows that the purported Navi variant leads significantly in the Aztec Ruins Normal Tier (1080p) and High Tier tests 1440p). This could imply that GCN6 in Navi is tailored more towards raw graphics than compute. We aren't exactly sure about the specs of this particular entry but expect to see variants with anywhere between 20 to 40 higher clocked CUs when Navi launches.
