Total War: Warhammer II (DX11)

Last in our 2018 game suite is Total War: Warhammer II, built on the same engine of Total War: Warhammer. While there is a more recent Total War title, Total War Saga: Thrones of Britannia, that game was built on the 32-bit version of the engine. The first TW: Warhammer was a DX11 game was to some extent developed with DX12 in mind, with preview builds showcasing DX12 performance. In Warhammer II, the matter, however, appears to have been dropped, with DX12 mode still marked as beta, but also featuring performance regression for both vendors.

It's unfortunate because Creative Assembly themselves have acknowledged the CPU-bound nature of their games, and with re-use of game engines as spin-offs, DX12 optimization would have continued to provide benefits, especially if the future of graphics in RTS-type games will lean towards low-level APIs.

There are now three benchmarks with varying graphics and processor loads; we've opted for the Battle benchmark, which appears to be the most graphics-bound.

Total War: Warhammer II - 3840x2160 - Ultra Quality

Total War: Warhammer II - 2560x1440 - Ultra Quality

Total War: Warhammer II - 1920x1080- Ultra Quality

Wrapping things up for games is Total War: Warhammer II, and this title is one that is less than ideal for the matchup between the Radeon VII and its competitors. Much like GTA V, the card is able to make substantial improvements over its predecessor; at 4K, this is an astounding 47% increase over the RX Vega 64. Nevertheless, given the starting point of the RX Vega 64, the Radeon VII is still somewhere around 15% behind the reference RTX 2080, meaning that it performs a shade faster than the reference RTX 2070 at 4K/1440p. That's not where the Radeon VII ideally wants to be, despite being respectable way to iterate on the RX Vega 64.

    So FP64 is 1:4 and not 1:8 or 1:2 as previously known? Reply

    Yep, looks like they changed the cap in vBIOS based on feedback.

    Which also means they could have uncapped it, but it's still cool that they did that.

    Does that mean it could be potentially unlocked by some bios mod? Reply

    I hope so! Reply

    I don't think it was ever reported or assumed to be 1/2 - that best possible ratio is only for the pro MI50 part. Early reports said 1/16. Reply

    For what it's worth, when we first asked AMD about it back at CES, FP64 performance wasn't among the features they were even throttling/holding back on. So for a time, 1/2 was on the table. Reply

    So it was *your* fault! ;-p Reply

    Asrock just posted vBios: is this with the FP 1:4 or newer?

    We're not currently aware of any Radeon VII cards shipping with anything other than 1/4 rate FP64. Reply

    So maybe it's new bios with some fixes?
    Did you tried it since all cards are the same reference design?
