The divergent performance between the two graphics subtests are reflective of the particular workloads. The RX 580 was never intended for 4K gaming, and so is expectedly unsuitable. And despite its 4GB frame-buffer, the Fury X is able to hold its own despite having the bare minimum required VRAM. The results are largely unsurprising as we noticed historically and in our RX Vega review, AMD's graphics performance benefits more from DX12 environments than DX11. For the RX Vega cards, the default power profile (primary BIOS and 'Balanced'' profile) was used. NVIDIA’s 385.69 drivers and AMD’s Radeon Software Crimson ReLive Edition 17.9.3 were the drivers used. We also checked the effect of enabling 11.6GB of HBCC on the Vega cards. Overall, on our 8-core Skylake X GPU test bench, we looked at 9 cards with and without async compute disabled: the Titan Xp, GTX 1080 Ti, GTX 1080, GTX 1070, GTX 980 Ti, RX Vega 64, RX Vega 56, RX 580, and R9 Fury X. In general, the Time Spy and Time Spy Extreme benchmark scores do not relate to one another. With that in mind, we are only reporting graphics subscores and framerates. In other words, the score/measurement is not dependent at all with the graphical rendering work. To preface, Time Spy Extreme’s CPU test is a simulation, and the benchmark measures average simulation time per frame. For the time being, an advance release has been made available to the press, and we’ve taken a quick look at the benchmark with a selection of modern cards. Time Spy Extreme will be released to the public on October 11. Like the original, Extreme was developed with input from Futuremark’s Benchmark Development Program, a group that includes AMD, Intel, and NVIDIA. Ultimately, Time Spy and Time Spy Extreme engine was built for DX12 from the ground up, and incorporates marquee DX12 features: asynchronous compute, explicit multi-adapter, and multi-threading. We’ve covered the technical aspects when Time Spy was first released, and the underlying details are likewise the same. Otherwise, the sequence remains the same: the Time Spy explores a museum with artifacts and terraria of Futuremark’s other benchmarks, past and present. While the benchmark does not require a 4K monitor, the typical video memory demands are still present: Time Spy Extreme has VRAM minimum of 4GB, a step up from Fire Strike Ultra’s 3GB. Where the original Time Spy scaled poorly on 10+ threads, Time Spy Extreme’s CPU test was redesigned for CPUs with 8 or more cores, and is additionally able to utilize AVX2 and AVX512 instruction sets. The original Time Spy was already more intensive than Fire Strike Ultra, and Time Spy Extreme brings that graphical punishment to 4K. Slotting into the 3DMark suite, Time Spy Extreme is available under the Advanced and Professional Editions on Windows, focusing on DX12 functionality on contemporary high-end graphics cards as well as high-core count processors. This week, Futuremark unveiled Time Spy Extreme, a 4K version of the DX12 gaming benchmark released last July.
